Door Installation in San Antonio - Written Price Before Anything Is Ordered

Trusted Door Installation for San Antonio Homeowners

Door Installation in San Antonio involves more than swapping a slab and calling it done. Our climate punishes entry doors: summer heat bakes west-facing jambs, spring storms drive water against thresholds, and the humidity swells wood until locks bind. A door installed without accounting for these conditions will fail within a few seasons. Lightwell Windows San Antonio has been part of the Cedarwell network since 2010, and our crews install entry doors, sliders, French doors, and storm doors with a written price before any work starts. If you want to talk through what a new door should cost in your part of San Antonio, call (325) 420-4173 and a live person answers, day or night.

Front Door Replacement

Front Door Replacement is the single highest-impact door project most San Antonio homeowners take on, because the front door is what neighbors see, what guests touch, and what burglars test first. Lightwell Windows San Antonio replaces front doors on homes from Alamo Heights to Helotes, and most jobs fall between $1,800 and $4,500 depending on the door material, glass package, and whether the frame needs remediation. A typical replacement takes one day from removal to final caulk, and the written estimate covers the slab, hinges, lockset prep, weatherstripping, and interior trim work so the number you agree to is the number on the invoice.

Glass and Light Packages

San Antonio’s sun is hard on decorative glass. We recommend double-glazed units with low-E coatings for west-facing entries, and our Therma-Tru and ViewLux lines offer fiberglass doors with factory-installed glass that will not cloud or leak over time. If you want privacy without losing light, patterned glass options let you skip a curtain while keeping the living room out of sight from the street.

Frame and Threshold Repair

A new door in a rotted frame will sag within a year. Before any front door replacement in San Antonio, our technician checks the king studs, jack studs, and sill plate for moisture damage. If the frame shows rot, we quote the repair in the same written estimate so there is no mid-job surprise.

Door Replacement

Door Replacement covers any interior or exterior door that has outlived its function, whether it binds, rattles, leaks air, or simply looks tired against a freshly painted wall. Lightwell Windows San Antonio handles slab-only swaps and full frame-out replacements, with most interior door replacements running $400 to $900 per opening and exterior replacements starting around $1,500 and climbing based on material and hardware. We carry Mr-Glass and ECO Window Systems products, which gives us a broad price ladder from builder-grade hollow core to solid-core and insulated steel.

When a Slab Swap Is Enough

If the existing frame is square, level, and dry, replacing only the slab saves money and keeps your trim intact. We bring pre-hung slabs for interior work and custom-measured slabs for exterior applications, then mortise the hinges and prep the lockset on site. This works especially well in older San Antonio neighborhoods like Terrell Hills, where original trim is worth preserving.

Full Frame-Out Replacements

When the jamb is split, the threshold is rotted, or air moves around the casing, a slab swap will not fix the problem. We remove the old frame to the rough opening, shim the new one to true, and insulate the gap before reinstalling casing. The C.A.R.E. value that applies here is Explain the price before the work: you can see the difference between a slab quote and a frame-out quote in writing before we touch the opening.

Sliding Glass Door Replacement

Sliding Glass Door Replacement addresses doors that stick mid-track, fog between panes, allow water under the sill, or have frames so worn the lock no longer engages. In San Antonio, replaced sliding glass doors most often go in on homes in Timberwood Park and Castle Hills, where large glass openings face hot afternoon sun. A typical slider replacement runs $2,200 to $5,000 installed, depending on glass package, frame material, and whether the existing opening needs resizing. We install thermally broken aluminum and vinyl sliders from ECO Window Systems and CWS, both of which hold up against San Antonio’s UV load better than builder-grade originals.

Roller and Track Upgrades

The rollers are the part that fails first on a slider, especially when pet hair and Hill Country dust collect in the track. When we replace a sliding glass door, we install sealed-bearing stainless rollers and an elevated track profile that sheds debris instead of collecting it. This is the difference between a door that glides for a decade and one that hangs up again in two years.

Glass Spec for West-Facing Sliders

If your slider faces west, standard clear glass will cook the room behind it. We spec low-E glass with a solar heat gain coefficient appropriate for San Antonio’s cooling-dominant climate, which keeps the room cooler without making it dark. Keith Yamada, owner at Lightwell Windows San Antonio, routinely checks the orientation of each opening before recommending a glass package, because the right coating on a west wall pays for itself in lower cooling bills.

Storm Door Installation

Storm Door Installation puts a second door on the outside of your primary entry to catch wind, rain, and UV before they reach your main door. In San Antonio’s storm season, a storm door also lets you keep the main door open for air while keeping pets and kids inside. Lightwell Windows San Antonio installs storm doors from ViewLux and Therma-Tru, with most jobs running $600 to $1,400 depending on the door size, glass, and hardware package. Installation typically takes two to three hours, and the price includes removal of the old storm door if one exists.

Pet and Kid Considerations

Storm doors with glass full-height are a hazard for a running toddler, which is why we walk through your household’s daily patterns before recommending a panel layout. A mid-rail door with a solid lower panel keeps small hands from pushing through glass, and a self-closing hinge prevents pets from slipping out when the door drifts open. For homes with big dogs, we recommend the reinforced lower panel and a pneumatic closer with an adjustable speed so the door never slams.

Hardware and Color Matching

Most stock storm doors come in white or almond, but your house may not. We match the storm door finish to your existing entry hardware and trim color, and we can order through ViewLux in darker bronze and clay tones that sit quietly next to San Antonio’s limestone and stucco facades. The written estimate includes the color-matching fee, so there is nothing on the back end.

Sliding Glass Door Installation

Sliding Glass Door Installation is for openings where a swinging door would eat floor space, typically a patio, balcony, or a side yard connection off a kitchen or den. Lightwell Windows San Antonio installs new sliders in existing openings and in newly framed openings, with installed pricing typically $2,200 to $5,200 depending on the panel count and glass specification. Products from ECO Window Systems and PGT give us access to impact-rated glass for homes near Lackland AFB and multi-panel configurations for wide openings in newer Door Installation in New Braunfels and Selma builds.

Impact-Rated Options

For homes in wind zones or on exposed ridgelines like Helotes, our Door Installation in Helotes includes impact-rated sliding glass doors that are worth the upgrade. These units use laminated glass and reinforced frames that hold together even if the outer pane fractures. The price difference is real, but so is the protection when a stray branch or hail stone hits the glass at speed.

Multi-Panel and Pocket Configurations

Some San Antonio homes have wide openings that single-panel sliders cannot span. We install two-panel and three-panel sliders, including pocket configurations where panels disappear into the wall. These jobs require more framing work, and the written estimate reflects that upfront, including drywall repair around the pocket if the opening is being widened.

Door Repair

Door Repair covers the mechanical and weatherseal problems that make a door hard to use: sticking edges, failed hinges, worn thresholds, misaligned strikes, and frozen locks. Lightwell Windows San Antonio repairs doors throughout San Antonio, and most repairs run $150 to $600, with the written estimate based on the specific problem found during inspection. Not every sticky door needs replacement; in many cases, the fix is a hinge adjustment and a new sweep, and we would rather quote you the smaller number and earn your trust for the next job.

Alignment and Hinge Repair

A door that rubs at the top corner usually has a hinge problem, not a door problem. We pull the hinge screws, plug with hardwood dowels, and reset the leaf so the door hangs true. On doors with sagging top corners from years of use, this is often a one-hour fix that saves you the cost of a full replacement.

Weatherseal and Threshold Work

In San Antonio, failed weatherseals show up as dust on the sill and a room that never holds temperature. We replace compression sweeps, raise or lower thresholds, and add corner pads where air sneaks around the hinge side. If the existing threshold is still sound, we resurface it rather than replace it, which keeps the repair bill low.

Exterior Door Installation

Exterior Door Installation includes front entries, side entries, garage man doors, and patio access doors, any door that separates conditioned space from San Antonio’s outside air. Lightwell Windows San Antonio installs exterior doors from Therma-Tru, ViewLux, and PGT, with typical pricing between $1,500 and $4,200 installed depending on material, size, and hardware. Every exterior door installation includes new weatherstripping, a sill pan or threshold flash, and shims that set the door square so the deadbolt engages cleanly.

Energy and Air Sealing

An exterior door is only as efficient as its perimeter seal. We install sill pans under every exterior door in San Antonio, because wind-driven rain will find any gap at the threshold and migrate into the subfloor. The exterior trim is caulked with a sealant rated for our UV exposure, and the interior casing is insulated before the trim goes back on.

Security Hardware Prep

We prep every exterior door for a deadbolt with a reinforced strike plate anchored into the framing, not just the jamb. This matters in San Antonio neighborhoods where door kick-ins are a common entry method. Our technicians follow the C.A.R.E. values here: Ask before drilling, Respect the family’s schedule by minimizing noise, and Explain the hardware options in the written estimate before any work starts.

French Door Installation

French Door Installation brings in a pair of hinged doors that swing open for a wide passage, usually onto a patio, courtyard, or back porch. Lightwell Windows San Antonio installs exterior French doors and interior French doors, with exterior units typically running $2,800 to $6,000 installed and interior units between $900 and $2,400 depending on glass and material. We carry French doors from Therma-Tru and ViewLux in fiberglass and wood, and every exterior French door installation includes the weather sealing and sill flashing described in the exterior door section above.

Exterior French Doors and Water Management

Exterior French doors have a seam where the two leaves meet, and that seam is the failure point in a San Antonio rainstorm if the astragal is not set perfectly. We install interlocking astragals with a drip cap, and we seat the fixed leaf so the active leaf compresses the weatherstrip evenly along the full height. The write-up detailing our clean-up is part of the job too: drop cloths under the saw, shoe covers through the house, and a photo of the finished threshold before we leave.

Interior French Door Installations

Interior French doors open up a study or dining room without a full wall removal. We hang both leaves on ball-bearing hinges so they swing with one hand and stay where you leave them. If you have a dog that scratches at doors, we can spec a solid lower panel or a glass pattern that hides paw prints between cleanings, and the recommendation goes in the written estimate so you know what you are buying.

Brands We Service

Lightwell Windows San Antonio services and installs doors from eight manufacturer lines, and we have deep familiarity with Therma-Tru fiberglass entry doors, which we spec for their resistance to rot and their factory-finished colors that do not fade under San Antonio sun. We also install ViewLux storm doors and French doors, and we stock their common hardware kits for faster repair turnarounds. ECO Window Systems supplies us with vinyl and aluminum sliders that handle our climate’s thermal swings without warping.

Whether your door is a Therma-Tru, a ViewLux, an ECO Window Systems unit, or another make entirely, our techs can diagnose and fix it. We order parts direct from the manufacturer when needed, and we do not push a replacement when a repair is the honest answer.

Signs You Need a Pro Right Now

• You can see daylight around the door perimeter. If light passes through, so does air, dust, and water. This is a weatherseal failure that will get worse with each rain and each summer.
• The door scrapes the floor or sticks at the top. This usually means hinge wear or frame settling. Forcing the door open damages both the door and the floor finish, and a pro can typically fix the alignment in under an hour.
• Water stains appear on the interior floor near the threshold. Water entry at a threshold moves under flooring and into the subfloor, where it rots silently. Repairing the sill flash now costs far less than replacing subfloor later.
• The deadbolt will not fully engage without lifting the handle. A misaligned strike plate is a security issue, not a nuisance. If you have to lift or pull the door to lock it, the house is not secured against forced entry.
• Condensation fogs between slider glass panes. This is a failed seal on an insulated glass unit. The door still slides, but the glass has lost its insulating value, and in San Antonio’s heat that shows up directly on your cooling bill.

Our Process, Step by Step

1. 1
   Call and talk to a person. When you call (325) 420-4173, a live person answers and records your address, the door in question, and your availability. No voicemail maze.
2. 2
   On-site measurement and inspection. A background-checked, uniformed technician arrives with shoe covers on before stepping inside. We measure the opening, check the framing and threshold, and talk through what you like and dislike about the current door.
3. 3
   Written estimate. You get a line-item price in writing that covers materials, hardware, installation labor, and clean-up. The number on that page is the number on the invoice, always.
4. 4
   Installation day. The crew lays drop cloths to every work path, asks before moving any furniture or decor, and uses quiet tools during nap windows if you have small kids. For exterior doors, we install a sill pan and re-flash the threshold as part of the standard scope.
5. 5
   Walk-through and clean-up photo. Before we leave, we walk the door with you, show you the clean-up, and take a photo so the condition of your home is documented. The 365-Day Done Right Promise stays on the job: if something is not right, we make it right.
