Fast, Reliable Impact Windows & Doors Across Lake Mary
Impact windows and doors in Lake Mary typically run $900-$2,800 per opening installed, with most full-home replacements landing between $18,000 and $45,000 depending on window count, custom sizing, and HOA requirements. That’s the honest range, and it’s what we quote from the start. Our crews work Lake Mary neighborhoods every week, from Heathrow to Timacuan to the Chase Groves corridor. Call (954) 280-4413 and a live person answers, 24 hours a day, every day.
What makes Lake Mary different from Orlando or Sanford isn’t the heat or the storms. It’s the double gate every homeowner has to pass through before a single window gets ordered: Seminole County permits and your HOA’s Architectural Review Committee. We’ve walked enough Heathrow and Timacuan applications through both to know exactly what gets held up, and how to keep a job moving while the paperwork clears.
Why TruePane Windows & Doors Is Lake Mary’s Preferred Impact Windows & Doors Company
We’re not the cheapest bid you’ll get in Lake Mary, and we won’t pretend otherwise. We’re the company homeowners call after a cheaper crew set a window out of true, or registered only one warranty layer, or left a fogged double-hung in a Timacuan great room and stopped answering the phone. Dale Kessler founded TruePane in 2008 on a rule he keeps on the whiteboard to this day: if the pane is not true, the job is not done. We stand behind that in writing.
Our Impact Windows & Doors team knows Lake Mary’s housing stock because we’ve been inside it since 2008 as a company, through a second-generation glazier’s craft tradition. Not a franchise playbook. We hire local, train apprentices into journeymen, and act like a company that plans to be in Seminole County thirty years from now. You don’t build that reputation by dodging callbacks on a corroded sliding door threshold.
Every technician who steps onto a Lake Mary property is background-checked and uniformed. Every opening gets measured twice. Both warranty layers get registered in writing before the truck leaves your driveway. If something’s not done right within 90 days, we make it right. No paperwork fights, no arguing, no fine print that covers neither. That’s The Keystone Standard, and it applies to every job we do in Lake Mary.
Our Impact Windows & Doors Services in Lake Mary
Hurricane Impact Windows
Lake Mary sits inland, but Florida Building Code wind-borne debris requirements still mandate impact-rated glazing or approved storm protection on every new and replacement window here. The UV index in Seminole County runs among the highest in the continental US, which is why builder-grade vinyl frames from the 1990s are failing faster than their manufacturer projections ever anticipated. We replace them with impact units sized to your actual opening, including the arched and palladian shapes that came standard in Heathrow’s two-story great rooms.

Impact Sliding Glass Doors
Homes built in Lake Mary between roughly 1988 and 2005 came with aluminum sliding glass doors that now corrode at the threshold after 20-35 years of Central Florida humidity. Afternoon convective storms push water straight into those failing tracks. We replace them with impact-rated sliding doors set on new thresholds, with insulated glass that stops the seal failure and the water intrusion in one job. On tight lots, we stage everything on your driveway and keep the street clear for neighbors.

Impact Entry & French Doors
Entry doors on Lake Mary’s stucco homes take the same code hit as windows: impact-rated or protected. French doors from the late 1980s luxury era often have original single-pane glass that doesn’t come close to current Florida Energy Code minimums. We quote manufacturer lines side by side on paper so you see exactly what you’re buying, and we register both warranty layers before we leave.

Impact Garage Doors
Garage doors are the most overlooked wind-borne debris opening on a Lake Mary house, and the first to buckle in a storm if they were never braced or replaced. We install impact-rated garage doors that meet Seminole County code, coordinate with your HOA on any exterior appearance requirements, and handle the wind mitigation documentation that can lower your insurance premium.

Wind Mitigation & Code Compliance
This is the paperwork half of the job, and in Lake Mary it’s where projects stall. Seminole County requires permits on window and door replacements. HOAs in Heathrow and Timacuan require Architectural Review Committee approval before work starts. We prepare both applications, attach manufacturer spec sheets for the exact impact units being installed, and keep the process moving even when an arched transom needs a custom insulated glass unit with a three-month lead time. Wind mitigation inspections and the resulting documentation go to your insurer, not into a drawer.

Trusted Brands We Service in Lake Mary
We’re an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. For Lake Mary’s impact-specific work, we regularly quote CGI, CWS, and ECO Window Systems side by side on paper so you can see the price difference, the design pressure ratings, and the warranty terms before you commit. We keep local inventory moving for common Lake Mary sizes, and for custom arched units from ES Windows we order the templated insulated glass the day the HOA approves the submittal. No second appointment left hanging.
Common Impact Windows & Doors Problems We See in Lake Mary Homes
- Fogged double-hungs in Heathrow and Timacuan. Builder-grade double-hung windows from the 1990s lose their argon gas and fail their seals after two decades of humidity. The fog between the panes means the insulated glass unit is dead, and on non-standard shapes that’s a custom order, not a shelf pull.
- Corroded aluminum sliding door thresholds. Late 1980s and early 1990s stucco homes have aluminum frames that corrode at the threshold line. Lake Mary’s afternoon storms drive water through those pinholes and into the floor framing.
- Arched and palladian windows that no standard impact unit fits. The era’s luxury construction made non-standard shapes a signature feature. Today they’re a sizing problem: standard impact windows don’t come in eyebrow transom dimensions, and the custom insulated glass units take weeks to manufacture.
- HOA and permit deadlocks. A Heathrow homeowner with a fogged arched transom can wait months while the ARC holds the application and the custom IGU is being made. We’ve seen HOAs reject impact window styles because the frame profile didn’t match the original builder spec.
Pricing for Impact Windows & Doors in Lake Mary, FL
A standard impact window in Lake Mary runs $900-$1,400 per opening installed for common sizes. Impact sliding glass doors run $2,200-$4,800 depending on width and whether the frame needs full replacement or pocket retrofit. Arched transoms and palladian shapes push $1,800-$3,200 per unit because the insulated glass is templated and custom-made. Full-home replacements on a typical 2,200-square-foot Heathrow home land between $18,000 and $38,000. What moves the number: window count, custom shape count, frame condition, second-story access, and whether your HOA requires a specific frame color or profile. We give written line-item quotes with fixed pricing. The quote we hand you is the price you pay. Call (954) 280-4413 to schedule your free estimate.

FAQs - Impact Windows & Doors in Lake Mary
Yes. Heathrow’s Architectural Review Committee requires written approval before any exterior window or door work begins, and they hold the application until your impact window submittal matches the community’s design specs. We prepare the ARC package with manufacturer spec sheets and frame profile details at the same time we file the Seminole County permit, so the two approvals run in parallel instead of back to back. Call (954) 280-4413 and we’ll walk you through what your specific HOA requires before you spend a dollar.
A custom arched or palladian impact window in Lake Mary takes 6-12 weeks from order to install. The insulated glass unit is templated specifically to your opening, manufactured, then set into a custom impact-rated frame. HOA approval can add 2-4 weeks on top of that if the submittal goes back for revisions. We submit the ARC package the same week you sign, before the truck even parks, so the clock is running on both the approval and the manufacturing at once.
You can replace just the insulated glass unit on many Lake Mary double-hungs and fixed windows if the frames are still square and the seals between frame and wall are intact. Fog between the panes means the IGU failed, not necessarily the frame. On corroded aluminum frames from the 1980s and 1990s, we usually recommend full frame replacement to impact-rated units because the frame itself is the weak point and won’t meet current Florida code. Call (954) 280-4413 for an exact assessment, and we’ll quote both options side by side.
Lake Mary’s municipal code restricts construction noise to daytime hours, generally 7:00 a.m. to 7:00 p.m. on weekdays, with tighter limits or outright bans on Sundays and holidays. HOAs in Heathrow and Timacuan often narrow those hours further. We schedule Lake Mary installs to start no earlier than 8:00 a.m. and finish before 6:00 p.m. unless your HOA allows otherwise, and we keep sawing and cutting to designated areas on your property so we don’t push sound toward shared walls or neighboring lots.
Some will, some won’t. Heathrow and Timacuan ARCs are strict about maintaining the community’s original architectural character, which means frame color, profile width, and glass tint have to match or closely approximate the builder spec. We quote impact lines that offer custom frame colors and narrow sightlines specifically because we have seen HOAs reject standard impact windows for looking too thick or too white. We bring the manufacturer’s finish samples to the estimate so you can hold the exact color against your stucco before the ARC even sees the submittal.
