Why Mason Remodeling Co San Antonio Is Castle Hills’s Preferred General Contractor Company
Castle Hills runs its own permitting and inspection department, separate from San Antonio. That is not a bureaucratic footnote. It means every structural change, window replacement, and addition gets a second, more demanding approval layer, and inspectors who enforce wind-load tables and foundation movement provisions that other contractors never see coming. We handle that process start to finish, so you’re not stuck correcting someone else’s expired San Antonio permit mid-job.
Isaac Pruett, our owner, has built Mason Remodeling around the Threshold Standard: every crew member is background-checked, identity-verified, and introduced to you by name and photo before they arrive. At the door, they show a photo ID badge and wear a clean, marked uniform. No strangers, no surprises. That matters in a place like Castle Hills, where letting someone into your home is a real decision, not a formality.
We also deliver a written price before any work begins, every time. That is not a promotion. It is how we run every Castle Hills project, from a bathroom remodel on a 1960s ranch to a full addition on a custom 1980s home. And every completed job is covered by our 365-Day Done Right Promise: if the work is not right within a year of completion, we return and make it right at no cost to you.

Hire a General Contractor in Castle Hills
Hire a General Contractor in Castle Hills when the project touches structure, windows, roofing, or any system your home depends on. This is where the local code gets real. Castle Hills requires its own permit for work that San Antonio would pass through under a different review, and inspectors here check wind-load ratings, foundation details, and drainage paths with more scrutiny. A general contractor who knows the Castle Hills process saves you weeks of rework and keeps the inspector sign-off moving.
Here is what that looks like in practice: if you’re replacing windows on a mid-century home, the Castle Hills permit review will ask for the impact rating against the local wind-load tables for your lot’s exposure category. A quote that skips that step is the one that stalls at inspection.
Permit-Heavy Projects
Additions and whole-home remodels in Castle Hills run $45,000 to $130,000, and the permit is a real line item, not an afterthought. We pull the Castle Hills permit, schedule inspections, and document every sign-off so your project is compliant from day one.
Structural and Window Work
Impact window installation runs $8,000 to $25,000 in Castle Hills. Standard window replacement with impact-rated units runs $4,500 to $15,000. Both require wind-load documentation that Castle Hills inspectors will actually review.
General Contractor Services in Castle Hills
General Contractor Services in Castle Hills cover kitchen remodels, bathroom remodels, whole-home renovations, room additions, garage conversions, and deck construction. On a pier-and-beam 1950s home, that often means working with the original cast iron plumbing and single-pane aluminum windows that are past their useful life. On a 1980s custom build, it means respecting the larger floor plan while correcting the same expansive clay soil movement that affects every foundation in this city.
Our General Contractor team coordinates the structural work, the finishes, and the permit trail together. You get one point of contact and one written price before any work starts.
Bathroom and Kitchen Renovation
Bathroom remodels in Castle Hills typically run $9,000 to $28,000 depending on scope. Kitchen remodels start at $14,000 and can reach $45,000 for a full gut renovation. We provide the line-item breakdown up front, so the final invoice matches the first number you saw.
Additions and Conversions
A garage conversion in Castle Hills runs $30,000 to $80,000. A separate ADU starts at $90,000. Both require the Castle Hills building department’s own permit and structural review, which we handle as part of the written scope.

Trusted Brands We Service in Castle Hills
Mason Remodeling works with specification-grade product lines including PGT impact windows, Tamko and Atlas roofing systems, and Boral building products when the job calls for them. For Castle Hills homes facing wind-load requirements, PGT’s impact-rated windows meet the documentation threshold inspectors check. For roofing, Tamko and Atlas both carry wind-rated options that satisfy Castle Hills code. We do not stock these brands in a Castle Hills warehouse; we order per project and stage locally so the materials arrive when the permit clears, not before the inspector is scheduled.
Common General Contractor Problems We See in Castle Hills Homes
- Expansive clay foundation movement. Castle Hills sits on the Blackland Prairie, where clay soils shrink and swell with moisture. Pier-and-beam homes from the 1950s and 1960s shift with every wet-dry cycle, and remodel plans that ignore the foundation get flagged at inspection.
- Single-pane aluminum windows that fail wind-load review. Most original windows in Castle Hills homes were never rated for current wind-load tables. The Castle Hills inspector will catch an underrated window spec on a remodel or addition that touches the building envelope.
- Cast iron plumbing at the end of its lifecycle. Original cast iron drain lines from the 1950s and 1960s corrode from the inside. A bathroom remodel that opens a wall often reveals pipe that has to be replaced before the inspector will pass the rough-in.
- Drainage problems around slab foundations. Flash flooding and clay soil combine to push water against foundations. Castle Hills inspectors often require drainage correction as part of the permit scope when an addition or patio changes the lot’s runoff pattern.
Pricing for General Contractor in Castle Hills, TX
Homeowners in Castle Hills ask what the real cost is, so here it is in writing. Window replacement with impact-rated units runs $4,500 to $15,000. Impact window installation, when the project is window-only, runs $8,000 to $25,000. A wind-rated roof replacement runs $8,000 to $20,000. A permit-heavy home addition runs $45,000 to $130,000.

We write the price after we know the scope, and that price is in writing before any work starts. Call (254) 269-5071 for a free estimate.

Wind-Load Compliance: What Castle Hills Actually Requires
Castle Hills enforces its own building code, and the wind-load provision is the one that separates a compliant quote from a cheap one. When a project touches the building envelope – windows, roofing, an addition – the Castle Hills inspector checks the product rating against the wind-load table for your lot’s exposure category. A San Antonio permit does not carry over. A verbal assurance that “it’s fine” does not pass inspection. The documentation has to be in the permit file.
On a 1960s ranch off Honeysuckle Lane, our crew replaced an original pier-and-beam foundation section and single-pane aluminum windows after the Castle Hills inspector flagged wind-load underrating on the planned sunroom addition. We pulled the separate Castle Hills permit, upgraded to impact-rated windows meeting local wind-load tables, and documented the load-bearing beam changes in the scope of work. Final inspection sign-off came through on the first pass. That is what local familiarity looks like in practice.
Here is why this matters beyond the inspector: your homeowner’s insurance carrier wants to see documented wind-mitigation upgrades. If you replace windows or a roof but cannot show the Castle Hills permit and inspection sign-off, the insurance adjuster has no record of the upgrade, and you likely paid for a premium reduction you will never receive. A compliant quote includes the permit, the inspection scheduling, and the documentation packet. A cheap quote leaves all three out.

FAQs About General Contractor in Castle Hills
Castle Hills requires your roof system to meet the wind-load rating for your lot’s specific exposure category under the city’s own building code amendments. For most Castle Hills homes, that means a wind-rated roof system with documentation from the manufacturer, not just a standard shingle upgrade. The inspector verifies the rating against the permit file before final sign-off. For an exact rating for your home, call (254) 269-5071 and we will check your lot’s exposure category as part of the free estimate.
Castle Hills requires its own permit for window replacement. San Antonio permits do not carry over, and the Castle Hills review is stricter on wind-load and structural documentation. We pull the Castle Hills permit, specify impact-rated windows that meet the local tables, and schedule the inspection so the sign-off is on file when you need it for insurance purposes. Call (254) 269-5071 for a free estimate that includes the permit line item.
A garage conversion in Castle Hills typically triggers structural, electrical, plumbing, and final building inspections, plus a wind-load review if the conversion touches the building envelope. The structural inspection is the one that catches most out-of-town contractors, because the original garage slab and framing were never designed as living space. Expect the inspector to check moisture barriers, insulation values, and the new foundation connection details. We schedule every inspection and stay on site through final sign-off. For a written scope for your garage conversion, call (254) 269-5071.
Yes, but only if the upgrade is documented with the Castle Hills permit and inspection sign-off. Insurance carriers apply wind-mitigation discounts when they can verify the impact-rated windows or wind-rated roof were installed and passed inspection. Unpermitted work gives the adjuster nothing to verify. We provide the full documentation packet with every window and roof project so you can submit it to your carrier. Call (254) 269-5071 for a free estimate that includes the compliance documentation.
Expansive clay movement is the issue Castle Hills inspectors look for first on older slab homes. If the remodel touches load-bearing walls or changes the foundation footprint, the permit review will ask for a foundation assessment and may require drainage correction as a condition of approval. We include that assessment in the written estimate so you are not surprised by a change order. Call (254) 269-5071 and we will walk your specific foundation condition before the first permit is pulled.
