A door does more work in North Texas than most homeowners realize. Between hailstorms that can pit a steel slab in minutes, summer afternoons that push exterior surface temperatures well past what the material was designed for, and clay soils that shift a house's frame season to season, the door assembly is one of the first things to show wear. Alpine Exteriors installs and replaces entry doors, patio doors, storm doors, and service doors across the Dallas-Fort Worth area, and we build every installation around the conditions this region actually produces rather than a generic national spec sheet.
Doors fail or underperform for different reasons depending on where they sit on the house, so we treat each opening on its own terms. That includes front entry doors and the sidelights or transoms around them, rear and side patio doors (both sliding and French/hinged pairs), storm and security doors layered over an existing entry door, and the service doors used on garages, mudrooms, and side entrances. The work covers the full opening — slab, frame, threshold, flashing, and hardware — not just swapping a door panel into an old frame and hoping it fits. If the existing jamb is rotted, out of square, or improperly flashed, that gets addressed as part of the job, because a new door hung in a bad frame will fail the same way the old one did.
There isn't one correct door material for this region — there's a set of trade-offs, and the right call depends on sun exposure, budget, and how much maintenance a homeowner actually wants to do.
We start with an in-person assessment and measurement, checking not just the rough opening size but whether the frame is actually square — a meaningful number of older DFW homes have door openings that have racked slightly out of square from years of foundation movement, and that changes how a new unit needs to be fit. From there we go over material and hardware options and set expectations on lead time; stock steel doors can often be installed quickly, but custom-sized or wood doors typically run several weeks on order.
On install day, the old door and, when needed, the frame are removed, and we inspect the sill and jamb framing underneath for water damage or rot before anything new goes in — installing a new door over a compromised sill just moves the problem down the road. The new unit is set, shimmed, and leveled, the threshold is flashed to shed water away from the framing, and the gap around the jamb is insulated rather than just caulked over. Exterior trim gets reset, hardware is installed and adjusted so the multi-point lock actually engages cleanly, and we finish with a full operational check and a walkthrough with the homeowner before cleanup and haul-away.
This is the part of the job that actually separates a door that lasts from one that doesn't in North Texas.
Hail. DFW sits inside one of the more hail-active corridors in the country, and it's common for a single storm to leave visible dents in steel doors and cracked or pitted glass inserts. If hail exposure is a real concern for a given opening, fiberglass slabs and impact-rated glass packages are worth the added cost — and if a storm does cause damage, photographing it promptly matters for any insurance claim.
Straight-line wind. Spring and early-summer storm systems here frequently produce straight-line wind gusts rather than sustained hurricane-force wind, but a strong outflow boundary can still rack a lightly built door or blow a poorly latched French door pair open. Multi-point locks and a solid astragal between double doors matter more here than in calmer climates.
Extreme heat and thermal cycling. A dark steel or wood door on a south- or west-facing wall can reach surface temperatures well above the surrounding air temperature on a summer afternoon, and that heat cycles down to near-freezing on winter nights. That daily swing is hard on finishes, adhesives, and weatherstripping, and it's a big part of why fiberglass tends to outlast wood or steel on unshaded exposures here.
Foundation movement. Much of the Dallas-Fort Worth area sits on expansive clay soils that shrink and swell with moisture changes through the year, and that seasonal movement is a well-known cause of sticking doors, gapped thresholds, and frames that go slightly out of square over time. A fresh door install can correct existing misalignment, but it doesn't stop future foundation movement — homeowners on active clay soils should expect occasional adjustment down the road, and that's a maintenance issue, not necessarily an installation defect.
Insurance. Most Texas homeowners policies, including in the DFW area, carry a separate wind/hail deductible that's often a percentage of the dwelling coverage rather than a flat dollar amount — that's different from the coastal windstorm pool (TWIA), which doesn't apply here, but it still means wind/hail claims on doors and glass can carry a higher out-of-pocket cost than other claims. Keeping receipts and product documentation for impact-rated materials can help both with claims and, on some policies, with modest premium credits.
Permits and code. Most DFW-area cities follow International Residential Code with local amendments, and a like-for-like door swap in the same opening typically doesn't require a permit, while resizing an opening or altering a load-bearing header usually does. Requirements differ by city, so we check the specific jurisdiction — Dallas, Fort Worth, Plano, and the surrounding suburbs don't all handle this identically.
Alpine Exteriors installs doors throughout the Dallas-Fort Worth metroplex, including Dallas, Fort Worth, Plano, Frisco, Arlington, Irving, McKinney, and Denton. If a property falls outside this list but nearby, it's still worth asking — service radius depends on current scheduling more than a hard boundary.
Do I need a permit to replace a door in North Texas?
Usually not for a straight swap into an existing opening of the same size. If the opening is being resized, or the header/framing is being altered, most DFW cities will require a permit. Requirements vary by city, so we confirm with the local building department before work starts on anything beyond a like-for-like replacement.
What's the best door material for a hail-prone area like DFW?
Fiberglass slabs generally hold up best against hail impact and won't dent the way steel can. For patio doors, laminated or impact-rated glass packages reduce the chance of a cracked pane during a hailstorm. No door material is completely hail-proof, but the difference in resistance between materials is real and worth discussing before ordering.
How long does a door replacement actually take?
The installation itself is usually a matter of hours per opening for a straight swap, sometimes longer if the sill or framing needs repair. The bigger time factor is often lead time on the door itself — stock units can be quick, while custom sizes, wood doors, or specific glass packages commonly take several weeks to arrive before installation can even be scheduled.
Will new doors lower my insurance premium?
Sometimes, modestly, if a carrier offers a credit for impact-rated products, but it's not guaranteed and varies by insurer. What's more consistently useful is having documentation of what was installed if a hail or wind claim ever comes up, since Texas policies commonly carry a separate wind/hail deductible that applies regardless of the door's condition beforehand.
Doors in North Texas take a real beating — hail, heat, wind, and shifting foundations all show up in how they perform over time, and the right material and installation details make a measurable difference in how long a door lasts here. Alpine Exteriors offers on-site assessments to look at your specific openings, sun exposure, and framing condition before recommending a material or product line, so the recommendation is based on your house rather than a generic sales sheet.
