Fast, Reliable Impact Windows & Doors Across Houston
Impact windows and doors in Houston must meet Harris County wind pressure ratings, period. You also need glazing that will not fog from our humidity, and if your house sits in a historic district like the Heights, the Houston Archaeological and Historical Commission adds a second layer of approval most contractors never mention. We work those requirements every week. TruePane Windows & Doors serves homeowners across Houston with impact-rated glazing, documented compliance, and a Done Right Promise on every job. Call (888) 635-0804 for a free estimate.
If you have priced impact windows before and walked away confused, you’re not alone. A quote that leaves out the permit path, the HAHC submittal, or the warranty registration is not a quote. It is a problem waiting for you to discover it. We put everything in writing before you sign. Both manufacturer warranty layers registered, durations stated, and the workmanship guarantee covers 90 days with no paperwork fights. That is how we do every window and door in Houston.
Why TruePane Windows & Doors Is Houston’s Preferred Impact Windows & Doors Company
We are not a franchise. TruePane was founded in 2008 by second-generation glazier Dale Kessler, and the company’s craft tradition runs many years deep. Dale keeps one rule on the whiteboard: if the pane is not true, the job is not done. Our Impact Windows & Doors team works to that standard on every Houston install, from a single replacement sash in Montrose to a full-home hurricane package in Woodland Heights.
Houston homeowners tell us the same thing after we finish: nobody else explained the wind-load code, the historic district rules, and the insurance paperwork in plain English. We measure every opening twice. We quote manufacturer lines side by side on paper, including CGI, CWS, and ES Windows, so you see exactly what you are buying. Background-checked, uniformed technicians handle the work. A live person answers our phone 24 hours a day, seven days a week. Not a voicemail tree.
Our Impact Windows & Doors Services in Houston
Hurricane Impact Windows
A compliant impact window in Houston carries an ASTM E1886/E1996 rating that meets or exceeds Harris County’s minimum design pressure for your home’s exposure category. Many homes inside the Loop, particularly in 77006 and 77008, fall into Exposure B or C depending on surrounding structures, and the required pressure rating changes accordingly. We specify the right glass package for your block, not a generic template. Impact-rated units with laminated glass, low-SHGC coatings below 0.25, and argon fill handle wind load, UV load, and Houston’s dew points in one spec.

Impact Sliding Glass Doors
Sliding glass doors in Houston take a beating from both sides: Gulf wind-driven rain against the exterior and 75% relative humidity pressing on the interior. Cheap tracks flex, rollers bind, and the door starts sticking in July. We install impact-rated sliding doors with reinforced interlocking stiles, stainless steel rollers, and properly flashed sills that shed water the way Houston requires. Most sliding door replacements in Houston run $2,800 to $6,500 installed, depending on width, glass package, and whether the rough opening needs reframing after years of moisture exposure.

Impact Entry & French Doors
Entry doors in Houston fail where you cannot see it: the threshold, the jamb flashing, and the seal behind the casing. After Hurricane Harvey, we replaced scores of water-damaged door frames in low-lying inner-loop blocks where the original installers had skipped flashing tape and jamb sealing. An impact-rated entry door with a reinforced frame and multi-point lock starts around $3,200 and runs to $8,000 or more for wider French door configurations with sidelights. We pull the permit, pass the inspection, and leave you the paperwork.

Impact Garage Doors
Your garage door is the largest opening in the house, and in a Houston windstorm it is also the most common point of structural failure. A non-rated door that blows in pressurizes the garage, and then the ceiling and roof want to leave too. Impact-rated garage doors with reinforced tracks and struts typically run $2,400 to $5,800 for a standard two-car opening. We also verify the door’s pressure rating against your home’s wind zone so the whole opening meets code, not just the panels.

Trusted Brands We Service in Houston
We are authorized installers for more than a dozen manufacturer lines, and on Houston jobs we commonly quote CGI, ES Windows, and ECO Window Systems because their glass packages handle our humidity and UV loads without giving up the wind ratings. We stock local parts for these brands near Houston, which means a replacement latch or a new sash for a blown seal does not sit in a warehouse in another state for two weeks. When you call us about a repair, we can usually tell you on the phone what we carry and what we have to order.
Common Impact Windows & Doors Problems We See in Houston Homes
- Blown IGU seals from dew points: Houston’s dew points sit among the highest of any major U.S. city, so between-pane fogging shows up years earlier here than in Phoenix or Dallas. A fogged impact window still meets wind-load code, but the visible failure becomes a problem on a resale inspection and an insurance claim after a storm.
- Big-box vinyl units failed HAHC review: A standard impact-rated vinyl double-hung meets Harris County wind code but gets rejected in Houston’s historic districts because the divided-lite pattern, sight lines, and frame material do not match the original. The homeowner already paid for the windows, then pays again for the rework.
- Non-rated sashes on pre-Harvey replacements: Some windows replaced after Harvey were single-glazed or non-impact units that do not meet current Harris County wind pressure ratings. They are non-compliant, and a diligent insurance adjuster will flag them after the next storm.
- Rot behind the flashing: When a cheap install skips flashing tape and jamb sealing, wind-driven rain wicks into the rough opening. Within two years the wood framing is rotting behind the trim, and by the time you see it, the repair is a structural job, not a window swap.
Pricing for Impact Windows & Doors in Houston, TX
A typical impact window replacement in Houston runs $1,100 to $2,400 per opening for a standard double-hung with a laminate glass package. Impact sliding glass doors average $2,800 to $6,500. Impact entry doors start around $3,200, and impact garage doors run $2,400 to $5,800 for a two-car opening. The main cost drivers are the required design pressure rating, glass package (low-E, argon, SHGC below 0.25), frame material (vinyl versus historically compatible wood), and whether the rough opening needs reframing after moisture damage.

FAQs - Impact Windows & Doors in Houston
Houston homes must meet the design pressure requirements set in the Harris County building code, which follows the International Residential Code with local amendments. The exact required rating depends on your home’s exposure category, building height, and location relative to the coast. A home inside the Loop with surrounding structures may fall under Exposure B, while a house on an open block or closer to Galveston Bay may be Exposure C, which carries higher pressure ratings. In practice, most Houston homes need impact units rated to DP 50 or higher, but we determine the required number for your specific address and put it in writing before you buy. Call (888) 635-0804 and we will verify the rating for your block.
In most cases, no. The Houston Archaeological and Historical Commission mandates that replacement windows in locally designated historic districts match the original divided-lite pattern, sight lines, and frame material. A standard vinyl impact double-hung fails HAHC review even if it meets Harris County wind code. Your options are historically compatible wood frames with impact-rated glazing, or specific vinyl lines that replicate the original sight lines closely enough to pass review. We have worked the HAHC submittal process in the Heights and Woodland Heights enough to know what passes and what triggers a rejection. On a 1920s craftsman bungalow in Woodland Heights, our crew replaced rotted original single-pane wood windows with impact-rated glazing in wood frames that matched the original 6-over-1 divided-lite pattern and sight lines. The old sashes had blown seals from Houston’s dew points, so we specified low-E glass with argon fill and a U-factor below 0.30 to handle both the wind-load code and the subtropical humidity.
A blown seal does not reduce the impact rating of the laminated glass itself. The laminate interlayer still holds, and the wind-load rating on the frame and glass package is unchanged. However, a fogged impact window raises questions on an insurance claim because the adjuster cannot see the glass condition clearly, and it will be flagged as pre-existing damage on a resale inspection. If you have a fogged unit, replace the IGU before storm season. Call (888) 635-0804 for an exact quote on a replacement sash or glass package.
A compliant Houston quote includes the specific design pressure rating for your home’s exposure category, the permit and inspection path, the HAHC submittal if you are in a historic district, flashing tape and jamb sealing in the scope, and both manufacturer warranty layers registered in writing with durations stated. A cheap quote gives you a per-window price and a handshake. The difference shows up six months later when the permit was never pulled, or the first wind-driven rain wicks into the rough opening, or the HAHC sends a violation notice. We put every compliance item in the written quote so there is no argument later.
Many Houston homeowners see a premium credit on the windstorm portion of their policy after installing impact-rated windows and doors, but the insurer requires documentation of a compliant install. That means the product rating certificate, the permit, and the passed inspection. Keep all three. We hand you the full compliance trail after every install: manufacturer rating documents, warranty registrations, permit paperwork, and inspection sign-off. Call (888) 635-0804 and we will walk you through what your insurer is likely to ask for.
