Fast, Reliable General Contractor Across Kirby
Hiring a general contractor in Kirby means finding someone who understands what hides inside 1950s and 1960s homes built on clay. Most Kirby houses sit on pier-and-beam foundations over soil that shifts with every drought and rain cycle, and that movement cracks walls, throws doors out of square, and compromises framing long before you see the first visible sign. Our crews serve Kirby regularly and know the streets, the housing stock, and the surprises that come with opening up an older home. Call (254) 269-5071 for a free estimate, and we’ll send someone who has worked on Kirby homes like yours.
Why Mason Remodeling Co San Antonio Is Kirby’s Preferred General Contractor Company

Kirby homeowners tend to ask the same question before they sign anything: who is actually coming to my door? We answer it plainly. Every technician is background-checked, identity-verified, and arrives in a clean marked uniform with a photo ID badge. You get the crew member’s name and photo before the visit, so the person who shows up is the person you expected. That is the Threshold Standard, and it applies on every job, in every Kirby neighborhood, without exception.
Our reputation in Kirby comes from doing the work the way older homes demand. We inspect before we quote. We write allowances into the contract for the things we know we will find: outdated wiring, cast-iron plumbing, damaged sills. And we do not start a project until you have a written price in hand. Kirby customers have told us that is the difference between a remodel that stays on budget and one that creeps by thousands of dollars.
When you call, a live person answers. Not a voicemail tree, not an answering service that passes along a message. 24 hours a day, 7 days a week, including holidays. That matters when a foundation shift has left your back door jammed shut and you need to know what you are dealing with before the weekend ends.

General Contractor Services in Kirby
General Contractor Services in Kirby cover the full scope of work a homeowner needs when renovating, repairing, or adding to an older home. In a city where most houses date from the post-World War II boom, the job usually starts with an honest look at what is behind the drywall and beneath the floor. A kitchen remodel in Kirby runs $14,000 – $45,000. A bathroom remodel runs $9,000 – $28,000. A home addition runs $45,000 – $130,000, depending on foundation work, framing, and the finish level.
Those are real numbers for this market. They include the surprises we expect to find in Kirby: undersized beams, rotted sills, outdated two-wire electrical, and original cast-iron plumbing with root intrusion. If you get a quote that seems dramatically lower, it usually means the contractor is not pricing the work a Kirby home will actually require.
Kitchen and Bath Remodeling
A kitchen remodel in Kirby typically means opening walls that have not been touched since Eisenhower was in office. Once the drywall is down, we find what we find: undersized framing, no insulation, wiring that cannot support modern appliances. We price the allowance for that work before we start, and we write any change order in plain language before we touch the unexpected item. No verbal surprises. No invoice that grows without your written approval.

Whole Home and Additions
Whole-home remodels and additions on Kirby lots require a contractor who understands how clay soil moves under a pier-and-beam foundation. We level before we build. We check the crawl space before we quote. That is the difference between an addition that stays square and one that develops a crack at the ceiling line within two years.

Construction Company in Kirby

Choosing a Construction Company in Kirby means choosing a firm that has seen what happens when older homes get renovated without proper inspection and permitting. We are Mason Remodeling, part of the Threshold Group family of home-service companies, and we have been doing this work since 2004. Every project starts with a real inspection of the structure, not just a walkthrough with a measuring tape.
We hold to a written-price standard on every job. That is not a promotion or a favor. It is how we work. Before a single tool is unpacked, you have a line-item written price that covers what we can see and what we expect. If we find something we did not expect, we write a change order, you approve it in writing, and then we proceed. That protects your budget.
Permitted Work and Inspection
We pull permits on every job that requires one. The permit triggers a third-party inspection, and that inspection is your protection. It catches undersized beams, incorrect wiring, and improper plumbing before the drywall goes back up. Skipping the permit saves a few dollars on paper and can cost tens of thousands when a hidden defect surfaces later.
Foundation and Structural Repair
Kirby’s expansive clay soils make foundation repair a near-universal concern. We check sill plates, joists, and subfloor alignment before we recommend any remodel. If the house has shifted, we address that first. You cannot install level cabinets on an unlevel floor.
Trusted Brands We Service in Kirby
We install and service the brands Kirby homeowners already trust, and we keep our relationships with manufacturers strong so our crews can get materials fast. We regularly work with Tamko roofing products, PGT impact-rated windows, and Boral siding and trim. When your remodel calls for a product we do not stock locally, we order it through our specification-grade partnerships and keep you informed on lead times. No vague promises about “sometime next month.” You will know when the materials arrive and when the crew is scheduled.

AfterCommon General Contractor Problems We See in Kirby Homes
- Pier-and-beam floor deflection: Decades of clay soil movement have shifted the beams, so floors slope toward the center of the house. We measure before we quote, and we do not install tile or cabinetry over a moving structure.
- Original cast-iron plumbing: Many Kirby homes still have their original cast-iron drain lines, and tree roots from mature oaks and pecans have been working on them for 60 years. When we open a floor or wall, we inspect the pipes and write a change order for repair before they leak.
- Outdated two-wire electrical: 1950s-era homes were wired for a world without microwaves, HVAC, or modern appliances. We price panel upgrades and re-wiring as a written allowance, not a surprise line item.
- Rotted sills and rim joists: Crawl space moisture and poor ventilation have been eating away at the wood for decades. When we find it, we show you photos, explain what it means, and price the repair in writing.

FAQs About General Contractor in Kirby
Yes, a crawl space inspection is necessary before any remodel on a pier-and-beam Kirby home. The shifting clay soils under Kirby have been moving the beams and joists for decades, and you cannot install level cabinets, tile, or framing over a structure that has shifted. We inspect the crawl space before we write the quote, and we include any foundation or framing repairs as a written line item, not a surprise later. Call (254) 269-5071 and we will schedule the inspection at no cost to you.
We write a change order for it, in plain language, before we touch the pipe. Cast-iron plumbing under Kirby homes is often compromised by root intrusion from mature oaks and pecans, and when we find it, we document it with photos, explain the repair, and give you a written price. You approve the change order in writing, and only then do we proceed. There is no scenario where we repair something and surprise you with the bill later.
A permit protects you by triggering a third-party inspection that catches undersized framing, incorrect wiring, and improper plumbing before the drywall hides it. It can add a few days to the schedule, but that delay is the cheapest insurance you will ever buy on a Kirby remodel. We pull permits on every job that requires one, and we schedule inspections as part of our project timeline, so you are never waiting on a surprise.
We write the allowances into the contract before we start. We know that a 1950s Kirby home will expose outdated wiring, cast-iron plumbing, and framing damage once walls are open, so we price those as written allowances up front. You will see the numbers before you sign. When we find something unexpected, we write a change order, you approve it in writing, and then we proceed. Your budget never moves without your signature. That is our General Contractor standard on every Kirby project. Call (254) 269-5071 to walk through the numbers.
The biggest difference is foundation type and the failure profile that comes with it. Kirby’s post-WWII homes sit almost uniformly on pier-and-beam foundations over shifting clay soils, so any remodel must assume framing, subfloor, and rough-in alignment have already moved. Central San Antonio has a mix of slab-on-grade and pier-and-beam on varying soil types, so a contractor who works mostly there may not price for the crawl space inspection, sill repair, and re-leveling that a Kirby job requires. That is the difference between a quote that holds and one that grows by thousands. Call (254) 269-5071 for a free estimate, and we will price your Kirby home the way it actually needs to be priced.
