Windows in North Texas take a beating that windows in most other parts of the country never see. Between hailstones the size of golf balls, straight-line winds that can gust past 60 mph ahead of a spring squall line, and a summer sun that pushes glass and frame temperatures well past 140°F on a south-facing wall, a window installed here needs to be chosen and installed differently than one going into a mild coastal climate or a snow-belt state. Alpine Exteriors installs and replaces windows across the Dallas-Fort Worth metro with that reality in mind, not a generic national spec sheet.
This is full-service window replacement and new-construction window installation, covering everything from a single failed picture window to a whole-house replacement. That includes removal of existing windows, repair of any rot or damage discovered underneath, installation of new units, flashing and air-sealing, interior and exterior trim work, and haul-away of old materials. We also handle smaller jobs — a bedroom egress window that no longer meets code, a bay window with a failed seal, or matching a single replacement to an existing product line after storm damage. If a hailstorm or wind event took out several windows on one side of the house, we can work directly from an insurance scope, though we'll tell you plainly where our estimate and the adjuster's numbers don't line up rather than just signing off on whatever the claim says.
Vinyl windows are the most common choice in North Texas and for good reason — they're the most affordable option, they don't corrode, and modern vinyl formulations handle UV exposure and heat cycling reasonably well. The trade-off is that vinyl frames expand and contract more than fiberglass with our wide seasonal swings, which over many years can affect how tightly a sash seats, especially on larger openings or dark-colored frames that run hotter in direct sun.
Fiberglass frames cost more up front — often 20-40% above a comparable vinyl unit — but they move far less with temperature, hold paint if you want a custom color, and generally hold up better on large or heavy sash configurations like sliders and bigger picture windows. Wood and wood-clad windows are available for homes where the look matters more than maintenance, but bare wood exposed to our humidity swings and sun needs real upkeep, and we're honest with clients that it's the highest-maintenance option in this climate. Aluminum frames are the least common recommendation from us for this region; they conduct heat efficiently, which is the opposite of what you want on a west-facing wall in July, so we typically steer clients toward vinyl or fiberglass unless a specific architectural requirement calls for aluminum.
On the glass side, dual-pane insulated glass with a Low-E coating and argon gas fill is the standard here, and it's sufficient for our climate zone — triple-pane glass, which makes more sense in northern states with long, brutal winters, is usually not worth the added cost and weight for a North Texas home. Where hail exposure and insurance considerations matter, we offer laminated glass packages rated to UL 2218 Class 4, the industry's highest impact rating; some Texas insurers offer a premium credit for these, though the discount amount and eligibility vary by carrier and you'll want to confirm with your agent before assuming a specific savings figure.
We start with an on-site measurement and a walk of the exterior to check flashing, sill condition, and whether the existing rough openings are square — a real question on many North Texas homes given the region's clay soils, which we cover below. From there we quote either a pocket (insert) replacement, which fits a new frame inside the existing one and is faster and less invasive, or a full-frame replacement, which removes everything down to the rough opening and is necessary when there's water damage, rot, or an opening that's shifted enough that a simple insert won't seal properly.
Once materials arrive — typically several weeks out for special sizes or colors, faster for standard stock sizes — install day involves removing the old unit, inspecting and repairing the framing underneath, setting the new window plumb and level, and sealing it with flashing tape and sealant rated for our temperature range rather than a generic caulk that will crack after a couple of summers. We foam or insulate the gap between frame and rough opening, finish interior and exterior trim, and do a function and water test before we call the job done. Most single-window replacements take a few hours; whole-house jobs typically run one to several days depending on window count and whether full-frame work is involved.
Hail is the single biggest factor driving window decisions here — North Texas sits inside one of the most hail-prone corridors in the country, and it's not unusual for a single storm to crack multiple panes on the same elevation of a house. No window is truly hail-proof, but laminated, impact-rated glass resists cracking and full penetration far better than standard annealed glass, and it's worth discussing even if you don't go with it on every opening. Straight-line wind ahead of thunderstorm lines is the other major load factor; windows here should carry a design pressure (DP) rating appropriate to their exposure, and larger openings on unshielded walls deserve a closer look at that rating than a small bathroom window would.
Thermal cycling is a quieter but real issue — a day that hits 105°F in August and a hard freeze in January (2021's multi-day freeze being the extreme example) put real stress on seals and frame materials over the life of the window, which is part of why we lean toward Low-E coatings and frame materials that handle expansion well rather than optimizing purely for lowest up-front cost. Foundation movement is worth flagging separately: much of North Texas sits on expansive clay soils that swell and shrink with moisture changes, which over years can rack window openings out of square, especially on slab homes with less rigid framing. That's usually cosmetic — a window that sticks or won't latch cleanly — but on older homes with visible foundation issues, it's a reason to favor full-frame replacement over a pocket insert, and it's also a reason no window installer, including us, can promise a lifetime perfect seal on a house that's still settling. Finally, most DFW cities require a permit for window replacement that changes the rough opening size, and bedroom windows have minimum egress size and sill-height requirements under the adopted residential code — we pull permits and confirm egress compliance as part of the job rather than leaving that on the homeowner. Texas homeowner's insurance policies also commonly carry a separate, percentage-based wind/hail deductible distinct from your regular deductible, which is worth knowing before filing a storm claim on window damage.
Alpine Exteriors installs and replaces windows throughout the Dallas-Fort Worth area, including Dallas, Fort Worth, Plano, Frisco, Arlington, Irving, McKinney, and Denton, along with the surrounding North Texas communities in between.
No, and we won't tell you otherwise. UL 2218 Class 4 laminated glass significantly reduces the chance of full breakage compared to standard glass, and it can help with insurance premium credits on some policies, but a large enough hailstone at the right angle can still crack or chip any window. It's a real upgrade in durability, not a guarantee.
It depends on the city and the scope. Straight swaps in the same rough opening often don't require one, while changes to opening size, egress windows, or structural framing typically do. Permit rules vary by municipality across the metro, so we confirm the specific requirement for your address before starting.
Pocket replacement is faster and less disruptive, and it works fine when the existing frame is square, dry, and structurally sound. Full-frame replacement costs more and takes longer but is the better call when there's rot, water damage, or an opening that's shifted from foundation movement — an insert into a compromised or out-of-square frame won't seal well long-term.
Costs vary widely by window size, frame material, glass package, and whether it's a pocket or full-frame install — a single standard vinyl window replacement often falls in a range of roughly $450-$900 installed, while fiberglass frames, impact-rated glass, or full-frame work push that higher. We provide a written itemized quote after the on-site measurement rather than a phone estimate, since opening condition affects price as much as the window itself.
If your windows are original to a home that's a few decades old, showing seal failure or fogging between panes, or you're rebuilding after storm damage, Alpine Exteriors can walk the property, measure openings, and put together a straightforward quote for pocket or full-frame replacement.
