Trusted Houston window installers, free in-home quotes, licensed & insured pros, workmanship warranty.
Window replacement in Houston answers to one thing above all: heat that refuses to quit. Summer highs sit near 95 degrees, the humidity off the Gulf makes it feel heavier, and the cooling season stretches across most of the calendar. Winter lows only dip to around 45 degrees, so your AC works far harder than your heater ever will. Old windows let the sun pour straight into your rooms and let the cool air you paid for leak back out.
Houston is the fourth-largest city in the country and the only major US city with no zoning, so a single block can hold a 1920s bungalow, a row of new townhomes, and a small office building. The housing runs from Craftsman bungalows in Houston Heights and older homes around Montrose to brick ranches in Bellaire and River Oaks, plus miles of newer subdivisions out toward Katy, Sugar Land, and The Woodlands. Plenty of those homes still have their original single-pane glass in thin aluminum frames. You feel it as rooms that never cool down in August, electric bills that spike from May through October, and condensation sweating on the glass.
Vetted local crews: the licensed installers we match you with do your job, so nothing gets handed off to a day-labor sub.
Upfront written pricing: every window, every charge, listed on one page. No change orders once the crew shows up.
Your installer handles any Houston permits: if your opening is being resized or your home sits in a Heights historic district, your installer files through the City of Houston Permitting Center and sees the inspection through.
Lifetime workmanship warranty: if the install ever leaks, sticks, or fails, your installer comes back and makes it right, and your manufacturer coverage stays intact.
Every style, built for the Gulf-Coast climate.
Two sashes ride up and down and tilt in for cleaning, the natural match for Heights and Montrose bungalows.
A side hinge and a crank push the sash wide open, pulling in a breeze and sealing tight when it shuts.
Runs side to side on a track, an easy pick for the wide openings in postwar ranches and suburban builds.
One large sealed pane, no moving parts, and low-gain glass that lets in light without the Gulf Coast heat.
Multi-panel units that step out past the wall, adding usable room inside and real presence at the curb.
Awnings hinge at the top so you can crack them during a Houston downpour, and garden windows give herbs a sunny shelf.
For Houston's hot, humid climate we most often install vinyl or fiberglass frames with Low-E 366 glass.

Houston sits in climate zone 2A, hot and humid on the Gulf Coast. Your windows here need to block sun first and insulate second. These are the specs we put on Houston homes:
| Spec | Recommended for Houston | Why |
|---|---|---|
| Glass coating | Low-E 366 (spectrally-selective) | 3,000 cooling degree-days |
| Frame material | Vinyl or fiberglass | Humid climate, 95°F highs, no rot or warping |
| Gas fill | Argon | Better insulation against the heat |
| U-factor target | ≤ 0.30 | Exceeds the Texas energy code requirement for zone 2A |
| SHGC target | ≤ 0.22 | Beats the code cap, and it is what blocks Gulf-Coast sun |
In Houston, SHGC does the heavy lifting. A low SHGC stops solar heat at the glass before it ever warms the room, which is exactly what you want across a cooling season this long. Houston electricity runs about 17 cents per kilowatt-hour, so a full set of low-gain, argon-filled units save about $563 a year on the ENERGY STAR published figure for this climate zone, or about $373 if you are replacing older double pane. The tighter seal also cuts down the humid air seeping in around worn aluminum frames.
Houston takes direct hits from Gulf hurricanes (Harvey, Ike, Beryl), so impact-rated windows are a smart upgrade for storm protection, and can help lower your home insurance premium. To be clear on code: most of Harris County is not in a state-designated windstorm zone, so impact windows generally aren't required here. Texas Department of Insurance windstorm rules apply mainly east of Highway 146 and in the coastal counties (see the TDI Harris County map). If your home is in that zone, we install TDI-approved impact windows and handle the WPI-8 certification. Ask about impact glass when you book your free quote.
Window installation in Houston usually runs $450 to $750 per installed double-hung window, or $8,000 to $15,000 for a full home. Older pier-and-beam houses in the Heights and Montrose take extra labor, since decades of shifting soil leave openings out of square and the original wood casing needs careful handling. Laminated or impact-rated glass costs more, and it buys you storm protection plus quieter rooms if you back up to a freeway or a busy feeder. With local home values around $325,000, new windows are one of the better returns you can get on a Houston house.

Houston keeps this simpler than most big cities. A like-for-like swap that keeps the same opening size generally does not need a permit. You do need one once you resize an opening, alter structure or a load-bearing wall, or add egress. If your home sits in one of the Heights historic districts, you need a Certificate of Appropriateness from the Houston Archaeological and Historical Commission before any exterior window change, and those design guidelines lean hard toward repairing or matching the original sash. Window performance follows the Houston Energy Code, which adopts the 2021 IECC with local amendments and took effect January 1, 2024, capping climate zone 2 fenestration U-factor and SHGC to the zone limits. Permits and inspections run through the City of Houston Permitting Center, and your installer files the paperwork and handles code compliance for you.

Usually not for a like-for-like swap that keeps the same opening size. You do need one if you resize the opening, touch structure or a load-bearing wall, or add egress. Homes in the Heights historic districts also need a Certificate of Appropriateness first. We pull whatever your job needs through the City of Houston Permitting Center.
For Houston's hot, humid zone 2A climate, we recommend Low-E 366 spectrally-selective glass with argon fill in vinyl or fiberglass frames. We target a U-factor of 0.30 or lower and an SHGC of 0.22 or lower, which beats the code caps.
Most Houston jobs run $450 to $750 per installed double-hung window, or $8,000 to $15,000 for a full home. Older pier-and-beam homes and impact-rated glass push the number toward the top of that range.
Houston electricity runs about 17 cents per kilowatt-hour, and your AC carries most of the year. On a typical home, energy-efficient windows save about $563 a year on the ENERGY STAR published figure for this climate zone, or about $373 if you are replacing older double pane.
It depends on your exact address. Much of Harris County sits inland of the windborne-debris region, so impact glazing is a choice rather than a requirement, while addresses closer to the coast fall under stricter rules. After Harvey and the flood events since, a lot of Houston owners pick laminated impact glass anyway for the storm and burglary protection, and some insurers give a credit for it. We check your address before we quote.
Yes. Every installer we match you with is licensed, bonded and insured in Texas, and their work carries a lifetime workmanship warranty from your installer alongside the manufacturer's warranty on the windows.
