Fast, Reliable Door Replacement Across Mayfair
Door replacement in Mayfair runs $850 – $4,600 for most exterior units, with interior doors typically landing between $350 – $1,200 installed. The wide range comes down to what’s behind the trim: older Mayfair homes rarely have stock-size rough openings. Our crew measures, orders the right unit, and installs it correctly the first time. Call (682) 281-2168 for a free estimate with written pricing before anything starts.
Mayfair isn’t a swap-and-go neighborhood. Pre-1980 construction, rear-alley setbacks, and tight lot lines mean most exterior doors here get custom-measured rather than pulled from a warehouse shelf. We know that because we’ve opened up enough jambs around Lakewood and the central residential pocket to expect the unexpected. That’s the job. Schedule your free estimate and we’ll scope it properly.
Why Juniper Windows & Doors Is Mayfair’s Preferred Door Replacement Company
Mayfair homeowners call us because we put the price in writing before a single screw turns. Sean Mackey set that standard from day one, and every tech on a Mayfair job follows it. No vague quote, no change order at the door, no “we’ll see what the framing looks like” pricing games. You get a line-item number you can hold us to.
We also answer the phone. Live, 24/7, a real person. When a rear door off an alley fails to latch and you can’t secure the house, that matters. You won’t get a voicemail maze or a callback queue.
Every Juniper tech is background-checked and uniformed. You’ll know exactly who’s walking through your gate. And every completed door carries the 365-Day Done Right Promise: if it’s not right, we make it right, parts and labor, in writing, for a full year.
Dispatch and scheduling for Mayfair are coordinated from the brand’s Los Angeles office, with local crews serving the neighborhood directly. That structure lets us keep the pricing discipline and product access of a larger operation while still showing up with a crew that knows Mayfair’s streets and building quirks.
Door Frame Repair in Mayfair
Door frame repair in Mayfair usually runs $225 – $650 depending on whether we’re shimming and re-securing an existing jamb or rebuilding the rough opening. In older homes near the central residential pocket, we frequently find jambs that were never properly shimmed when the original door went in. The frame pulls away from the studs over time, the deadbolt stops lining up, and the door starts binding at the top or dragging at the base.
A Mayfair homeowner needs frame repair when the door won’t latch, when daylight shows through the gap at the strike plate, or when the jamb has rotted at the bottom from years of sprinkler overspray and no sill flashing. Leaving it just puts more stress on the hardware until the door stops closing entirely.
Resetting an Out-of-Square Opening
Most pre-1980 Mayfair frames are out of square. Not by a little, either. We find half-inch to one-inch discrepancies regularly, especially on rear entries added or modified decades ago. We cut the old jamb free, re-level the opening, shim it tight, and set the new frame so the door hangs true.
Replacing Rotted Jambs and Thresholds
Frame rot at the base is the most common call we get in Mayfair. Moisture wicks up from unsealed concrete and compromised thresholds until the bottom foot of the jamb turns to pulp. We replace the rotted section or the full jamb, then install a new threshold with proper flashing and sealant so the fix lasts.
Interior Door Replacement in Mayfair
Interior door replacement in Mayfair typically runs $350 – $1,200 per door, installed with trim. That covers removing the old slab and hardware, prepping the existing frame if it’s sound, hanging the new door, and finishing the casing. If the frame itself is cracked or the opening is non-standard, count on the upper end of that range.
Mayfair homes with pre-1980 construction often have door openings that don’t match modern slab widths. A door labeled “30-inch” on the spec sheet may not fit a 29-inch rough opening without planing, and some of these older interiors have odd clearances we need to account for. We measure every opening before we order. That step alone eliminates most of the back-and-forth on interior jobs.
Matching Existing Trim and Hardware
Older Mayfair homes often have original casing profiles that are no longer stocked. We can match common profiles or install new trim that blends with the rest of the room. Same with hinges and handles. You don’t have to lose the character of the house just because the door itself is being replaced.
Sightlines and Natural Light
Replacing a solid interior door with a frosted-glass or full-view option changes how a hallway or laundry area feels. We help Mayfair homeowners pick glass that works for privacy and light, and we make sure the slab you choose actually fits the opening before we cut anything.
Trusted Brands We Service in Mayfair
Juniper carries and services eight product lines, and for Mayfair we lean on PGT, Therma-Tru, and ViewLux most often. PGT impact-rated units handle the neighborhood’s mixed exposure, Therma-Tru gives us fiberglass entry doors that won’t warp in heat, and ViewLux is our go-to for bright, modern sightlines on rear and side entries. Because we stock these locally, turnaround for Mayfair orders stays tight. We don’t make compromises on product because of supply chain excuses.
We also work on CGI and CWS doors already installed in Mayfair homes. If the unit was built right but the install was not, we can repair it. If the previous door was the wrong glazing spec, we’ll replace it with the right one and document it properly.
Common Door Replacement Problems We See in Mayfair Homes
- Stock-size assumptions on pre-1980 openings. A 32×80 door is standard, but Mayfair rough openings were often built by hand and are not square. Installing a stock unit anyway means binding at the jamb and a door that never closes right. We measure first. Always.
- Wrong glazing spec on exterior doors. Decorative or non-impact glass in a door here can fail the wind mitigation requirements and the opening’s design pressure rating. That’s not just a code issue. It’s a safety issue during storm season.
- Rotted framing and thresholds left in place. Swapping only the slab while the jamb and sill plate are soft is the fastest way to get a leaking door within one season. In Mayfair’s older homes, the frame is usually the problem, not just the slab.
- Alley-facing rear entries with fire ratings. Several Mayfair lots back onto alleys, which can change fire-rating requirements for the door assembly. We check the setback and the adjacent structure before we spec the unit, so you don’t get a correction notice later.

FAQs About Door Replacement in Mayfair
Yes, most exterior door replacements in Mayfair require a permit, especially when the opening size changes, the frame is rebuilt, or the door is in a fire-rated wall. We pull the permit, schedule the inspection, and walk the job through to final sign-off. Interior door swaps typically don’t need one. Call (682) 281-2168 and we’ll tell you which category your job falls into.
Impact-rated glass is engineered to resist wind-borne debris without shattering. In a door, that means the glazing stays intact under impact, the opening keeps its structural integrity, and you keep wind and water out. In Mayfair, where storm exposure varies by lot orientation, it’s worth confirming whether your opening requires it. We spec it when it’s needed and never install decorative glass where the rating matters.
A standard exterior door replacement takes one day, most of the time. If the frame needs rebuilding or the opening has to be resized, allow one to two days. Custom-ordered doors add lead time for manufacturing, usually two to four weeks. We’ll give you a calendar with real dates at the estimate stage, not vague “whenever the truck shows up” language. Call (682) 281-2168 for a timeline on your specific door.
Because Mayfair rough openings are not predictable. We’d be guessing at the framing, the jamb condition, and the true opening size. A quote over the phone means a surprise invoice later. Instead, we come out, measure everything, and you get a written price before any work starts. The estimate is free, and it’s the only way to give you a number that stays true.
It can, especially in Mayfair homes where afternoon sun hits the rear entries hard. A well-sealed, properly insulated door with low-U-factor glazing cuts the air exchange at that opening. In the central residential pocket, we’ve had homeowners report a noticeably tighter rear room after we replaced a drafty door and re-foamed the rough opening. It’s not a silver bullet for a whole-house cooling bill, but it helps at that opening, and it helps more if the old door leaked.
