French doors are one of the most requested upgrades we see across Dallas, Fort Worth, Plano, Frisco, Arlington, Irving, McKinney and Denton — and for good reason. They open up a back patio, brighten a dark dining room, and read as a genuine architectural upgrade rather than just a door swap. But North Texas isn't a gentle climate for exterior doors, and a French door that looks great in a showroom in Michigan can struggle here if it isn't specified correctly. This page covers what French doors actually are, how they hold up against our hail, heat and wind, and where they make sense versus where a sliding door is the smarter call.
A French door is a pair of hinged, mostly-glass doors that swing open from the center, usually out onto a patio, deck or courtyard. Unlike a single hinged door with a sidelight, both panels (or "leaves") of a French door are typically the same size and function, though many installations use one active panel and one fixed panel for practicality. Frames come in wood, wood-clad aluminum, vinyl, and fiberglass, and glass is almost always insulated dual-pane (sometimes triple-pane) with a low-E coating. In North Texas, the frame material matters more than almost anywhere else in the country, because it has to survive both 100-plus degree summer days and the occasional hard freeze without warping, swelling, or losing its seal.
The biggest single risk to a French door in this region isn't wind or heat — it's hail. Large-glass doors present a big, mostly-unprotected surface, and a severe hailstorm rolling through Collin, Denton or Tarrant County can crack or shatter an unprotected pane in seconds. Impact-rated glass (often the same laminated glass used in impact-rated windows) costs more up front but meaningfully reduces the odds of a mid-storm glass failure, and it can also factor into how insurers rate your Texas windstorm and hail coverage. If you're in an area that sees frequent hail events, this is worth discussing before you pick a door, not after one breaks.
Straight-line wind is the second consideration. Gusts ahead of a spring or summer line of storms can hit French doors broadside, and a door that isn't properly rated and installed can flex at the meeting rail, blow water past the weatherstripping, or in worst cases, pull away from the frame. Look for doors with a documented design pressure (DP) rating appropriate for an exposed patio location, and make sure the multi-point locking hardware — not just a single deadbolt — is actually engaging top and bottom, not just at the handle.
Then there's the heat. North Texas summers put exterior doors through daily thermal cycling: surface temperatures on a south- or west-facing door can swing more than 50 degrees between early morning and late afternoon. Over years, that cycling is what causes vinyl frames to warp, wood frames to check and crack at the joints, and cheap weatherstripping to go brittle and stop sealing. Fiberglass and wood-clad aluminum frames generally handle this expansion and contraction better than budget vinyl. A low-E, argon-filled glass package also matters more here than in milder climates — it's doing real work keeping west-facing summer heat out of the room behind the door.
Finally, foundation movement is a fact of life in this region's clay soils, and it shows up first at door and window openings. A French door that was installed perfectly plumb can develop a rubbing panel, a gap at the strike side, or a lock that no longer aligns as the house settles or shifts seasonally with soil moisture. This isn't unique to French doors, but because they're a paired, hinged assembly, even small frame racking is more noticeable than it would be on a single door — the two leaves stop meeting cleanly in the middle.
Pros:
Cons:
A well-built, properly installed French door in fiberglass or wood-clad aluminum will typically perform well for 20 to 30 years before major components need replacing, though the glass seal (the insulated unit) can fail sooner — 10 to 15 years is common — if it's a lower-tier product or was installed in a full-sun exposure. Solid wood French doors can look spectacular but need the most upkeep: expect to re-stain or repaint every few years to keep the wood protected from UV and moisture cycling, or the finish will fail well before the door itself does.
Maintenance that actually matters here: cleaning and lubricating the multi-point lock hardware once or twice a year so it keeps engaging correctly as the house shifts; checking and replacing weatherstripping when it goes stiff or cracked, usually every 5 to 8 years; and keeping an eye on the threshold and sill for gaps that let water or dust in during wind-driven rain. If a panel starts dragging or the two leaves stop meeting flush in the middle, that's usually foundation-related settling and worth having checked before it turns into a bigger air-and-water-seal problem.
The most common alternative homeowners weigh against French doors is a sliding patio door, and the comparison isn't close to one-sided. Sliding doors have fewer moving seals (no separate meeting-panel hinge system), a lower profile that's easier to fit into tight patio spaces, and they're generally less expensive to buy and install. They also tend to handle high wind loads slightly better in testing, since the panel rides in a track rather than swinging on hinges.
Where French doors win is the opening itself and the look. A slider only ever opens to half its total width, since one panel is usually fixed; a French door can open its full width, which matters if you move furniture, grills, or a wheelchair through that opening regularly. French doors also tend to look more custom and can be dressed up architecturally in ways a slider's aluminum track just can't match. If hail exposure and budget are the top priorities, we usually point homeowners toward a well-rated sliding door. If the opening is protected somewhat (a covered patio, a recessed entry) and the look and functionality matter more, French doors are worth the extra cost.
It's not required by code the way it is in coastal hurricane zones, but given how often this region sees severe hail, we recommend it for any French door that isn't under a covered patio. It's an upfront cost that can pay off the first time a storm rolls through.
It can go either way. Impact-rated glass and a documented wind/hail rating can sometimes help with premiums or claims history, while a large expanse of standard glass may be flagged during underwriting in hail-prone counties. Ask your insurer directly and keep the door's rating documentation on file.
Most replacements fit into an existing patio door opening without structural changes, though if you're converting a single door or a window into a French door opening, that does involve framing work. Alpine Exteriors evaluates the opening on-site before quoting, since foundation movement common in this area sometimes means the opening isn't perfectly square anymore.
For a mid-range fiberglass or wood-clad aluminum French door with insulated low-E glass, installed pricing in this market commonly falls somewhere in the $3,000–$7,000 range depending on size, hardware, and glass package; impact-rated glass and premium wood options push that higher. Get a few in-person quotes rather than relying on a national average — local install complexity and current material costs move the number.
French doors can be a genuinely great fit for a North Texas home, but the right glass package, frame material and hardware make the difference between a door that looks good for two years and one that performs for two decades through hail season, summer heat, and everything else this region throws at it. Alpine Exteriors installs and services French doors across Dallas, Fort Worth, Plano, Frisco, Arlington, Irving, McKinney and Denton, and we'll walk your specific opening, sun exposure and storm history before recommending a spec — not just sell you the door in the showroom.
