Door Frame Repair

Door Frame Repair is what we do before a new door goes in, when the surrounding wood or steel has rotted, split, or pulled away from the rough opening so badly that a replacement door can’t be hung square. In San Antonio’s heat and humidity, especially in neighborhoods like Alamo Heights and Terrell Hills where older homes have original wood jambs, we routinely find frames that look fine from the outside but crumble when you tap them with a screwdriver. Juniper Windows San Antonio replaces rotted sections with kiln-dried lumber or composite material that won’t absorb moisture the way the original framing did, then re-shims the opening so the new door sits plumb and level. Frame repair on its own usually runs $200 to $600 depending on how much material we’re cutting out; when it’s part of a full door replacement, it’s often absorbed into the job price we put in writing before starting.

Rot and Moisture Damage

Bottom corners of door frames are the first place water gets in, and once rot starts, it spreads behind the brick or siding faster than most homeowners expect. We cut back to sound wood, treat the remaining material, and rebuild with rot-resistant stock so the repair doesn’t fail in two seasons.

Misaligned or Sagging Openings

Foundation settlement is common across San Antonio’s clay-heavy soil, and it shows up as a door that scrapes the threshold or won’t latch. We re-shim and re-anchor the frame to the rough opening, correcting the geometry so the replacement door operates without binding.

Interior Door Replacement

Interior Door Replacement means pulling out an existing interior door and hanging a new one in the same opening, whether you’re matching original millwork in a Castle Hills mid-century home or upgrading hollow-core slabs to solid-core panels for better sound control. Homes in Scenic Oaks and Fair Oaks Ranch tend to have wider, taller openings than older San Antonio stock, so we verify every measurement before ordering. A standard interior door replacement runs $350 to $750 per door including the slab, hinges, hardware, and labor; pre-hung units with brand-new frames run $500 to $950. Juniper Windows San Antonio carries pre-finished options so you don’t have to live with primer doors while you schedule a painter.

Matching Existing Trim and Hardware

We match hinge finishes, backset dimensions, and trim profiles to what’s already in your home, so a replaced door doesn’t look like an afterthought. When an exact profile is discontinued, we’ll tell you before ordering and show you the closest match.

Solid Core Upgrades

Builders cut corners with hollow-core doors because they’re cheap, not because they’re good. Solid-core replacements make bedrooms and home offices noticeably quieter, and they weigh enough to hang straight without that flimsy rattle when someone walks past.

Interior Door Installation

Interior Door Installation covers new openings as well as first-time doors in rough-framed spaces, which is more involved than swapping an existing slab because we’re setting the jamb, casing, and stops from scratch. This comes up a lot in Converse and Kirby where owners are finishing out garages, adding pantry walls, or converting a flex room into a bedroom. Expect $500 to $950 per pre-hung door installed, including the frame, hinges, hardware, and casing; custom-sized openings or doors wider than 36 inches push toward the top of that range. We shim every jamb in three places per side and check reveal gaps with a gauge before we call it done, because a door hung even 1/16 inch out of square will find a way to remind you.

Pre-Hung Versus Slab Install

Pre-hung doors arrive with the slab already mounted in a new frame, which is the right call when the existing jamb is damaged or the rough opening is new. Slab installs reuse your existing frame and save money, but only make sense when that frame is still perfectly square and solid.

Closet and Bypass Systems

We also install interior closet door systems, including bifold and bypass configurations, with track hardware rated for daily use. A mirrored bypass door in a narrow Leon Valley hallway is the kind of small upgrade that changes how a room feels, and it usually installs in under two hours.

Door Installers

Door Installers on our team are the ones who show up at your San Antonio home with a live arrival time already sent to your phone, wearing a uniform and carrying the right shims, levels, and flashing tape for the job. Not every contractor who says they install doors actually handles the full scope: cutting back rotten framing, setting the sill with proper slope for drainage, and flashing the opening to keep wind-driven rain out. Our crew has been doing this in San Antonio since 2001, and every installer is background-checked before they ever walk through your door. Installation labor runs $150 to $400 per interior door and $400 to $1,200 per exterior door, depending on complexity, and it’s included in every written quote we give you.

What Background-Checked Means Here

Every technician who works under the Juniper Windows San Antonio name passes a criminal background check and wears a company uniform on every job. You’ll know the name of your installer before they arrive, and our office can verify their assignment if you call (903) 488-7019.

Tools and Technique

We set exterior doors with a 6-foot level across the threshold and check the reveal with a taper gauge, not by eyeballing it from across the room. Laser levels, moisture meters on existing framing, and high-expansion foam that won’t bow the jamb are standard on our trucks.

Door Contractors

Door Contractors differ from general handymen because doors sit at the intersection of carpentry, weatherproofing, and security, and getting all three wrong costs more than the door itself. Juniper Windows San Antonio is the door replacement specialist within the Relay Home Co. family, which means we’re not also bidding your kitchen remodel or your roof. Our work is limited to doors and windows, and that focus shows up in the details: the flashing sequence on a Therma-Tru exterior door, the reveal on a ViewLux patio door panel, the latch alignment on a Mr-Glass storm door where the closer tension has to be dialed in. Door contractor work in San Antonio typically runs $1,200 to $4,800 for exterior replacement and $350 to $950 for interior, with commercial-grade steel doors at the higher end.

Why Specialization Matters

A contractor doing ten trades can’t stock parts for eight door brands or tell you which glass package actually meets Texas windstorm requirements. We install doors every week in San Antonio, and that repetition means we’ve seen the failure modes a generalist hasn’t.

Written Pricing, No Change Orders

Our written price covers the door, the frame work, the hardware, the haul-away, and the cleanup. If we find something unexpected inside the wall, we show you photos, explain the fix, and write a change order before any additional work starts, so the number never moves without your signature.

Brands We Service

We work with Therma-Tru exterior doors more than any other brand because their fiberglass line handles San Antonio heat without the warping you see in cheap steel and without the swelling that plagues wood in humid months. We’ve installed hundreds of Therma-Tru entry systems across San Antonio, and we know their hinge prep, threshold profiles, and adjustability quirks well enough to set a reveal gap correctly on the first pass.

ViewLux patio and storm doors are a favorite in Windcrest and Alamo Heights where homeowners want glass that doesn’t fog between panes or rattle in a gust. We also stock and service Mr-Glass storm door hardware, including closers, sweep replacements, and retractable screen assemblies. If you have a PGT impact-rated door and you’re within San Antonio’s higher-wind zones, we can spec replacement glass and hardware that preserves the rating. Whether you have one of those brands or something else entirely, we’ll give you a straight answer about whether replacement makes more sense than repair.

Signs You Need a Pro Right Now

• You can see daylight around the door edge. That gap isn’t just an energy leak; it means the weatherstripping or the frame itself has failed, and water is likely getting in during San Antonio’s downpour season. We fix the sealing surface or replace the door and frame before the wall cavity takes on more moisture.
• The door scrapes the threshold or won’t latch. A door that suddenly stops latching is a settlement symptom, common in older San Antonio homes built on expansive clay. Left alone, the misalignment stresses the hinges and the strike plate until something gives.
• The bottom corner of the frame feels soft. Press a thumbnail into the jamb near the floor. If it sinks in, rot has started, and cutting out the bad wood now beats replacing wall studs later.
• Your exterior door is original to a home built before 2000. Those older units often lack the foam core and thermal break modern doors have, and their single-pane glass bleeds cooling dollars from May through October. Replacement pays back faster than most homeowners expect.
• You have to shoulder the door open. A door that binds means the frame has moved or the hinges have worn to the point where the geometry is off. Forcing it open every day accelerates the damage and is a sign you need professional attention before the next hard rain.
