How long does an automotive install take?
Most vehicles take 2-3 hours for a full vehicle window tint installation. Adding the windshield extends installation by approximately 1-1.5 hours. Specialty vehicles (vans, full-size trucks, anything with complex rear glass) can run longer — we'll tell you up front when you book.
Auto
When can I roll my windows down after tint?
We recommend waiting 2-3 days before rolling your windows down after installation so the adhesive can properly cure.
Auto
Does window tint go on the inside or outside of the glass?
Automotive window tint is installed on the inside of the glass. That protects the film from weather, debris, and car-wash brushes.
Auto
What should I do to prepare my vehicle?
Not strictly required, but helps: remove personal items from the doors and rear deck, clear trunk/cargo of anything blocking glass, and pull out child seats or hanging accessories near windows being tinted.
Auto
Can you tint in the rain or cold weather?
Yes. Window tint is installed indoors in a controlled environment, so weather conditions don't affect the install. The film will take a little longer to cure in colder weather.
Auto
Can window tint be removed?
Yes. Professional removal is the safe path — we use steam and proper solvent. Single-window removal starts at $35; a full vehicle is typically $225.
Auto
Is window tint legal in Missouri?
Yes. Front-side windows must legally let in at least 35% VLT (±3%). Rear-side and back glass have no limit. Windshield tinting beyond a non-reflective top strip is a medical-permit install. We can cut to any VLT you ask for — darker than the limit is for off-road or show use and requires a signed customer-liability waiver at install.
Auto
Is windshield tint legal in Missouri?
Missouri legally allows a non-reflective visor strip above the AS-1 line. Full-windshield tint is normally a prescription / medical permit install; non-medical installs are available on a signed customer-liability waiver for off-road or show use.
Auto
Can police ticket you for tint?
Yes — if your tint is darker than Missouri's legal limit, officers carry handheld meters and can issue a fix-it ticket. Going below the legal limit is your call; we ask you to sign a customer-liability waiver acknowledging the install is for off-road or show use.
Auto
What is ceramic window tint?
Ceramic tint uses advanced ceramic particles to block heat and UV rays. FormulaOne Pinnacle Plus targets up to 88% of the infrared spectrum — the part of sunlight you feel as heat through the glass. The flagship FormulaOne Stratos uses a Hybrid-Matrix nano-ceramic that pushes that IR (heat) rejection up to 97%. Neither contains metal, so cell, GPS, Bluetooth, and key-fob signals pass through clean — and both stay color-stable for the life of the film.
Auto
What's the difference between the three film tiers?
Classic is FormulaOne's dyed entry tier — privacy, UV protection, scratch-resistant, color-stable for life, lifetime warranty. Great look at the lowest install cost.

Pinnacle Plus is FormulaOne's nano-ceramic. Adds significant IR (heat) rejection — up to 88%. IR is the infrared portion of sunlight, the part you feel as heat through the glass on a sunny day. Cabin runs 10-20°F cooler without going darker. Non-metallic, so no signal interference.

Stratos is the FormulaOne flagship — Hybrid-Matrix nano-ceramic with up to 97% IR (heat) rejection (the maximum the catalog ships) and up to 65% Total Solar Energy Rejection (TSER — the holistic heat metric including absorbed-then-re-radiated energy). Same non-metallic, signal-friendly construction as Pinnacle Plus, just dialed all the way up.
Auto
Does tint protect my vehicle interior?
Yes. Window tint blocks harmful UV rays that fade upholstery and crack dashboards. Over the life of a vehicle, this is one of the biggest practical benefits of film.
Auto
Does tint block heat in a car?
Yes. Quality tint reduces heat by blocking infrared radiation — the IR portion of sunlight is what you actually feel as heat through the glass. FormulaOne Pinnacle Plus (nano-ceramic) cuts up to 88% of IR for a 10-20°F cooler cabin. FormulaOne Stratos pushes that to up to 97% IR (heat) rejection — the maximum in the catalog.
Auto
Will tint make my car darker inside?
A darker shade lets less light through, so looking out will read dimmer than untinted glass — most noticeably at night. That comes down to the shade you pick and how bright it is outside, not the type of film. What a quality film like LLumar adds is a crisp, distortion-free view at any legal shade. If night visibility is a priority, we'll steer you to a lighter VLT up front.
Auto
Does tint reduce driving glare?
Yes. Window tint significantly reduces glare from sunlight and headlights. High-quality films retain clarity at night. Cheap dyed film is what gets people in trouble at night.
Auto
Does tint affect GPS or cell signal?
No. All LLumar films we install are designed to allow electronic signals to pass through without interference. Carbon and ceramic films contain no metal.
Auto
How long does automotive window tint last?
High-quality automotive film like LLumar lasts many years — typically the life of the vehicle — when properly installed.
Auto
How do I schedule an automotive install?
Call (314) 400-8428 or use the online quote form. We send a customized quote and a couple of openings via email.
Auto
Can I wait while my car is tinted?
Yes. We have snacks, streaming, and Wi-Fi. Most customers prefer to drop off since installs run 2-3 hours.
Auto
How much does automotive tint cost?
Three 2026 tiers — full-install starting prices: Classic dyed $199 · Pinnacle Plus ceramic $279 · Stratos FormulaOne $449. Final number depends on your vehicle class and which windows. Use the online quote for an exact, posted-public number. We service vehicles model-year 2006 or newer.
Auto
Do you tint windshields?
Yes. Non-reflective AS-1 top strips, factory-spec full windshield tint, and full-windshield tint — typically for customers with a Missouri medical permit, or on a signed customer-liability waiver for off-road / show use.
Auto
Can I tint just my front two windows?
Yes. Common request if the rear glass already came factory-darkened. Starts around the half-price mark of a full install.
Auto
What does residential window film actually do?
It depends on the film. Heat-rejection films cut solar gain up to 80% — south- and west-facing rooms stay 10-15°F cooler all afternoon, your HVAC stops cycling, and your hardwoods stop fading. Privacy films give one-way daytime privacy or full frosted privacy. Safety films hold the glass together during break-in attempts or storms. Most homes get a mix.
Residential
Will film hurt my dual-pane / low-E windows?
We pick films that are approved for dual-pane glass. The wrong film on the wrong glass can cause thermal stress and crack the inner pane — that's why we sample on-site before quoting. Every LLumar residential film comes with a warranty that covers seal failure on dual-pane glass when the right film is matched to your window.
Residential
Does residential film go on the inside or outside of the window?
Almost always the inside — same as automotive. It's protected from weather and easier to clean. Exterior film is only used in rare cases (very specific window types where interior application would void manufacturer warranty).
Residential
How do I clean tinted residential windows?
Wait 30 days after install for the adhesive to fully cure. After that, use a soft cloth + ammonia-free glass cleaner. No abrasive pads, no razor blades on the filmed side. Same care as any high-end interior glass.
Residential
How much does residential film cost?
Installed pricing depends on the film family you pick. Per the 2026 rate schedule:
  • Neutral (entry solar / heat / UV): $9/ft² standard, $7/ft² volume rate (250+ ft²)
  • Dual Reflective (most popular — daytime privacy + solar): $11/ft² standard, $10/ft² volume
  • Reflective (mirrored privacy, strong heat rejection): $11/ft² standard, $10/ft² volume
  • Deluxe (top-tier solar/glare): $14/ft² standard, $12/ft² volume
Per-job minimum is $350 (covers our drive, setup, and a real install — applies if the sq-ft total falls under that). Rates include 15% over net measured glass to cover trimming. Use our residential quote form for an instant price band; we come out and measure for free before locking the final number.
Residential
How long does a home install take?
Most homes are a single-day install. A 350-400 sq ft job (typical south + west exposures on a 4-bedroom house) is 4-6 hours. We work room by room; you can keep living in the house while we work.
Residential
Will residential film change how my home looks from the curb?
Most heat-rejection films we install are nearly invisible from the street — they look like clean glass. Dual-reflective privacy films do read as slightly mirrored from outside during the day (and disappear at night when interior lights are on). We bring real samples to your on-site measurement so you can hold them against your glass and see exactly how it'll look from both sides before you decide.
Residential
How much will window film actually save on my cooling bill?
Highly variable, but homeowners with significant south + west glass typically see 10-20% lower cooling costs in summer months — your HVAC simply doesn't have to fight as hard. The bigger win for most St. Louis homes is comfort: rooms that were unusable from 2pm-7pm in July suddenly become livable. Payback on the film is typically 4-7 years on energy alone; the comfort upside is immediate.
Residential
Can I get daytime privacy without losing my view?
Yes — dual-reflective film is built for exactly this. During daylight (when outside is brighter than inside) it reflects the outside back at the viewer, giving you full one-way privacy. From inside you still see out clearly. At night the relationship inverts when interior lights are on, so curtains or blinds are still useful for after-dark privacy.
Residential
Do you do bathroom / shower / decorative privacy film?
Yes. Frosted privacy films, gradient frosted patterns (clear top, frosted bottom for half-privacy), and full decorative patterns. Common applications: bathroom and shower glass, transom windows, office doors, sidelights next to front doors. Goes on existing glass — no need to replace anything.
Residential
Will my HOA approve residential window film?
Usually yes. Most HOAs are concerned with exterior appearance — and the heat-rejection films we install on the inside surface look like clean glass from the curb (no visible color or reflectivity change). Dual-reflective and highly-reflective films can draw HOA scrutiny since they read as mirrored from outside. Bring us your HOA's spec sheet and we'll match a film that passes review.
Residential
Will residential film harm my houseplants?
For most houseplants — no. Standard heat-rejection films still let through 70%+ of visible light, which is what plants photosynthesize on. Darker privacy films can stress sun-loving plants (succulents, citrus, fruiting plants) in already-low-light rooms. If you've got an indoor garden by a specific window, tell us at the measurement and we'll pick a film that preserves the light spectrum plants care about.
Residential
What's the best film for protecting hardwoods + art from fading?
Fading is driven mostly by three things — UV (about 40%), visible light (about 25%), and heat / infrared (about 25%) — with the rest from humidity, age, and the dyes themselves. LLumar architectural films block 99% of UV across the board. To get the maximum fade protection (90%+ reduction in fade rate), you want a film that also cuts visible light transmission and solar heat gain — typically a dual-reflective or ceramic film. For a collector with serious artwork or rare hardwood floors, we'll spec a specialty fade-control film.
Residential
Can residential film slow break-in attempts?
Yes. 4-mil and 8-mil safety film on ground-floor windows and sliding patio doors holds the glass together when struck, turning a 5-second smash-and-grab into a 1-2 minute noisy struggle. Most opportunistic burglars give up and move on. Same film also contains shattered glass during severe weather and protects against flying debris. Looks like clean glass — nobody knows it's there until they need it.
Residential
What kinds of commercial buildings do you film?
Offices, storefronts, medical and dental practices, restaurants, warehouses, schools, and municipal buildings across St. Louis — anything from a single storefront to multi-story office floors. Government contracts and quotes welcome.
Commercial
How thick should our safety / security film be?
4 mil for standard safety (contains glass shards on impact). 8 mil for smash-and-grab resistance — the most popular tier for retail and storefronts. 14-16 mil for severe-impact and blast mitigation (federal facilities, schools, high-target buildings). All LLumar safety films meet ASTM E1886/E1996 standards.
Commercial
What's the ROI on commercial solar film?
Most buildings see payback in 2-4 cooling seasons. For a typical 5,000 sq ft west-facing St. Louis office, LLumar nano-ceramic film cuts roughly $1,200-$3,500/yr in cooling costs (about 25-30% HVAC load drop). That's before factoring in longer-lasting interior finishes and reduced glare complaints from employees.
Commercial
How much does commercial film cost?
Installed pricing per the 2026 rate schedule, by film family:
  • Neutral (entry solar / heat / UV): $9/ft² standard, $7/ft² volume rate (250+ ft²)
  • Dual Reflective (most popular commercial solar — daytime privacy + heat): $11/ft² standard, $10/ft² volume
  • Reflective (mirrored privacy, strong heat rejection): $11/ft² standard, $10/ft² volume
  • Deluxe (top-tier commercial — specified for demanding buildings): $14/ft² standard, $12/ft² volume
  • Security / safety film: $12-20/ft² depending on mil thickness
  • Decorative / frost / branded: $10-23/ft² depending on complexity
Per-job minimum is $500 for commercial. Building type can shift the number 5-10% (medical/restaurant slightly up for careful staging; warehouse slightly down). Use our commercial quote form for a price band; we follow up to schedule a free on-site walk and put the exact number in writing.
Commercial
Will the install shut my business down?
Almost never. We schedule around your operating hours — early mornings, evenings, weekends. Most retail and office installs are room-by-room with the business open. Heavy industrial jobs sometimes need a short closure window; we'll tell you up front.
Commercial
What is anti-graffiti film and how does it work?
A clear sacrificial layer applied to the outside of high-exposure glass (storefronts, bathroom mirrors). When it gets tagged, scratched, or acid-etched, we peel it off and replace it — instead of replacing the glass. Each glass replacement avoided saves the building owner thousands and a week of downtime.
Commercial
Can you do branded / decorative film?
Yes. Frosted privacy, custom patterns, logo cutouts, gradient frost, full printed designs. We can match your brand colors and produce graphics in-house. Goes on existing glass in a single visit, removable when you rebrand or move out.
Commercial
Do you write quotes for property managers / building owners?
Yes — multi-building and portfolio quotes are routine for us. We'll come walk the property (or all of them) and write a consolidated proposal with per-building and total line items. Volume pricing kicks in past ~10,000 sq ft of glass. We carry full commercial liability insurance and can provide a COI for whichever entity needs to be named.
Commercial
Can you film a multi-floor office building?
Yes. We install interior film on glass up to any height a building's interior allows — multi-story dental, medical, and corporate office glass included. For exterior glass on tall buildings, we coordinate with property management for boom-lift or swing-stage access.
Commercial
How does commercial film hold up against severe weather and hail?
Safety film doesn't stop the glass from breaking — it stops broken glass from going anywhere. During severe weather or hailstorms, an 8-mil safety film holds shards in the frame, protects interior occupants from flying glass, and keeps the building envelope sealed long enough to get a board-up or replacement scheduled. For high-target weather zones we recommend 8-mil minimum on every pane of single-pane glass.
Commercial
Will commercial film void our window manufacturer's warranty?
Not when we spec it right. Major commercial window manufacturers (PPG, Vitro, Guardian, Cardinal) publish approved-film lists for their glass — we pull from those lists, document the install for your records, and the LLumar dual-pane warranty kicks in as backup if anything ever goes sideways. Before quoting, we ask for your window manufacturer info; if it's not on file we contact them directly.
Commercial
Do you bid for government / municipal / school contracts?
Yes. We're set up for public-sector work — school districts, municipal buildings, and government facilities. We can match your procurement process — sealed bids, RFP responses, COOP buying programs, prevailing wage requirements. We carry the insurance, certifications, and LLumar authorization that public-sector contracts require.
Commercial
Can commercial film be removed or replaced if we rebrand or relocate?
Yes. Decorative and branded film is designed to come off cleanly when you change your look or move out — we can do the removal and prep the glass for whatever's next. Solar and safety film typically stays for the life of the building, but is also removable if a future tenant wants different optics.
Commercial
What financing or terms do you offer on commercial jobs?
Commercial jobs run on a 50% deposit at scheduling, with the balance invoiced net-30 after install. We accept card, ACH, and check.
Commercial
Will employees notice we installed film?
For solar / heat-rejection film: barely. Most modern architectural films are nearly clear from inside — employees might notice the glare is gone, but won't see the film itself. For dual-reflective or decorative film, the change is more visible. We bring samples to the walk-through so leadership knows exactly what the space will look like before signing.
Commercial
What is LLumar?
LLumar is the flagship window-film brand of Eastman Performance Films, a division of Eastman Chemical Company (Fortune 500 specialty-materials company). They engineer and manufacture every roll — automotive, residential, and commercial — and back every install through their authorized installer network with a manufacturer limited warranty.
AutoResidentialCommercial
What does "LLumar authorized installer" mean?
It means we're trained in Eastman's install standard, we're vetted to carry the LLumar brand, we have access to the entire LLumar catalog (not just a couple of films), and Eastman empowers us to honor the manufacturer's limited warranty on every install we ship. Authorized installers are also the ones Eastman backs up if a warranty claim ever needs to be made.
AutoResidentialCommercial
What warranty comes with the tint?
Every install is backed by an Eastman / LLumar manufacturer limited warranty against peeling, bubbling, cracking, adhesion failure, delamination, and color/fade defects. Automotive (FormulaOne) film carries a lifetime limited warranty for as long as you own the vehicle. Architectural film (residential + commercial) carries a limited warranty — the exact term depends on the film line and application. If anything covered fails, bring it back and as an authorized installer we replace it. It doesn't cover damage from accidents, vandalism, or razor-blade scraping on the filmed side.
AutoResidentialCommercial
What if my tint bubbles or peels?
Bring it back. Anything covered by the manufacturer warranty gets replaced at no cost to you per the warranty terms.
AutoResidentialCommercial
Does tint turn purple over time?
Cheap films do. LLumar's modern dye stack and ceramic films are color-stable. If yours discolors, that's a warranty issue and we'll replace it.
AutoResidentialCommercial
Will my tint have bubbles after installation?
Small water bubbles are normal post-installation — residual moisture between the film and the glass. These typically disappear within a few days to a couple of weeks. Anything still bubbling after that, bring it back.
AutoResidentialCommercial
Does tint block UV?
Yes. Every LLumar film we install blocks up to 99% of harmful UV rays — both UVA and UVB. That's true across the entire catalog: automotive, residential, and commercial. It's the cheapest sunscreen you'll ever buy.
AutoResidentialCommercial
How far in advance should I book?
Appointment availability varies by season. We recommend at least a few days in advance. Cooler months sometimes have same-day; mid-summer (June–August) can book weeks out for auto. Residential and commercial typically lead 1–2 weeks from quote to install.
AutoResidentialCommercial
What's your service area?
Both shops serve a 25-mile radius from the shop — that covers basically all of St. Louis County and the inner metro at no travel charge. Beyond 25 miles: 26-40 mi adds a $60 flat trip fee; 41-60 mi adds $120; over 60 mi bills at $1.25/mi round trip. Multi-day or out-of-state jobs factor lodging/per-diem into the written quote.
AutoResidentialCommercial
What are your payment terms?
Residential: 50% deposit at scheduling, balance on completion. Material deposit is non-refundable once your film is cut.

Commercial: 50% deposit at scheduling, balance invoiced net-30 after install.

We accept card, ACH, and check. Quotes are valid 30 days from the written estimate.
ResidentialCommercial
Why is the billable square footage higher than my measured glass?
Industry-standard 15% cutting/waste factor. Every pane is cut from a roll, which leaves trim strips and seam offcuts that can't be reused. We measure each pane at its widest and tallest points (glass only, not frame), total it up, then add 15% to cover real material loss during install. It's baked into the per-square-foot rates on our estimator — you don't get charged extra for it, but it's why your billable sq ft on the written quote is slightly higher than the bare measurement.
ResidentialCommercial
Is residential / commercial LLumar film different from the automotive films?
Yes — different product lines optimized for the application. Architectural film (residential + commercial) is engineered for flat glass at building scale: dual-pane compatibility, larger sizes, and a focus on solar heat gain coefficient (SHGC) reduction. Automotive film is engineered for curved automotive glass: dye + adhesive stack designed to heat-shrink to compound curves. We carry both.
