Fast, Reliable General Contractor Across San Leon
General contractor work in San Leon, TX looks different than it does fifteen miles inland. The salt air, the storm surge, and the pilings under your house change which materials survive and which ones fail. We plan for that from the first walkthrough, and we write the number down before we touch a tool. Penhallow Remodeling Houston serves San Leon homeowners with kitchen remodeling, bathroom remodeling, and whole-home work, with a live person answering calls around the clock at (254) 527-5340. Trevor Nash leads our team, and he holds every job to the Kingswell standard: a written price up front, a real arrival window, and a 365-day promise to come back and make it right if anything fails.
Why Penhallow Remodeling Houston Is San Leon’s Preferred General Contractor Company

San Leon sits unincorporated in Galveston County, which means no city inspector walks your job. The county checks a few things, but the rest comes down to the contractor’s own standard. That is where most cheap bids fall apart here. A general contractor who learned the trade in the inland suburbs will use electro-galvanized nails and standard deck screws, and those rust through in three to five years from bay salt spray. Our crews know which materials survive on the bay side, and we put it in the scope before work starts.
Homeowners in San Leon call us after other contractors have already burned them. That is the pattern. They had a verbal estimate that doubled after demo day, or a repair that cracked again before the next hurricane season. Our answer is the same every time: a written price, a written guarantee, and a crew that shows up in uniform with background checks already done. The General Contractor team works under the 365-Day Done Right Promise. If the work fails inside the guarantee period, we come back and fix it at no charge. That promise is on every project, in writing, before we pull a single permit.
Styles & brands we work with







Hire a General Contractor in San Leon
Hire a General Contractor in San Leon when the job touches the structure, the electrical, the plumbing, or anything that holds back water. A kitchen remodel here runs $14,000 to $45,000 depending on cabinet line, countertop material, and whether we are reworking load-bearing walls. A bathroom remodel runs $9,000 to $28,000. A home addition starts around $45,000 and can reach $130,000 when you are adding square footage on pilings. Those numbers come with a written scope and no verbal guesswork.
Coastal-spec materials
Near Galveston Bay, the difference between a ten-year job and a three-year job is usually the hardware. We specify hot-dip galvanized or stainless steel fasteners, marine-grade sealants, and pressure-treated or engineered lumber rated for ground contact. The cheap spec costs more within a decade. We would rather you pay for the right clip now than for a whole new deck frame later.
Permit and code reality
Because San Leon has no city building department, Galveston County reviews the structural and flood-related items. We handle the permit submittal, the elevation requirements, and the wind load details, and we tell you up front what the county will ask for. No surprises after the framing is open.
General Contractor Services in San Leon
General Contractor Services in San Leon cover kitchens, bathrooms, whole-home remodels, room additions, and the repair work that bay-side living keeps generating. We also handle deck construction, which in San Leon almost always means rebuilding over salt-exposed pilings with corrosion-resistant framing. Whether you need a new kitchen or a stilt house fixed, we write the full scope, line by line, before any demolition starts.
Kitchen and bath remodels
We install KraftMaid cabinetry and Cambria, Silestone, or Caesarstone countertops, with Kohler and Moen fixtures. Those product warranties stack on top of our own 365-day promise. A small kitchen remodel in San Leon runs $9,000 to $20,000; cabinet installation runs $4,000 to $13,000.

Whole-home and structural work
Whole-home remodels in San Leon frequently involve opening walls and finding salt-corroded framing or old hurricane repairs that were never done right. We address the structure before the finishes. Room additions run $45,000 to $130,000 depending on whether we are building up on pilings or out on grade.

Trusted Brands We Service in San Leon
We source materials from brands that carry their own warranties, because our 365-Day Done Right Promise works better when the product behind it is solid. For San Leon projects we regularly specify James Hardie siding and trim, which holds up against the humid, salt-heavy air far better than wood lap siding. On kitchen work we use KraftMaid cabinetry. On outdoor structures and storage we work with Tuff Shed. When we quote these products, we quote the coastal-spec hardware that holds them to the house, not the inland version that rusts out in five years.
Common General Contractor Problems We See in San Leon Homes
- Rotted wood pilings under older stilt houses. Many San Leon homes still sit on original 1970s wood pilings, and shipworm plus rot at the mud line is a failure we see regularly on the bay side. When those posts give way, floors sag and tile cracks.
- Rusted roofing fasteners and flashing. The salt spray from Galveston Bay eats standard electro-galvanized nails fast. Roof replacements in San Leon run $8,000 to $20,000, and the coastal-spec version uses stainless or hot-dip fasteners that hold.
- Deck and stair framing with untreated pine. Humid air wicks moisture into untreated pine at the post base, and the whole structure fails within a decade. We rebuild with pressure-treated posts and stainless hardware.
- Impact windows spec’d wrong or skipped. Hurricane exposure here makes impact-rated windows a real consideration, not an upsell. Impact window installation runs $8,000 to $25,000 depending on opening count and frame material.

FAQs About General Contractor in San Leon
Yes. Galveston County requires a permit for structural foundation and piling work in San Leon, because the county’s floodplain and wind load rules apply even though the city has no building department. We pull the permit, schedule the county inspection, and write the scope so the inspector sees exactly what we do. Call (254) 527-5340 and we will tell you what your specific foundation requires.
Because the materials are different. In San Leon we specify stainless steel or hot-dip galvanized fasteners, marine-grade sealants, pressure-treated or engineered framing, and impact-rated windows that meet the wind exposure along the bay. Those products cost more up front than the inland-spec versions, but the inland-spec job fails in three to ten years from salt corrosion. You either pay for the right hardware now or pay for the repair later, and the later version always costs more.
Check the fasteners first. Every screw, nail, and bolt should be stainless or hot-dip galvanized, not electro-galvanized. Check that the posts are pressure-treated and set above grade with proper post bases. Check the ledger flashing against the house. If any of those details are missing, the deck will not survive the salt air. We include all of them in our written scope and walk the finished deck with you before we call the job done. Call (254) 527-5340 if you want a second set of eyes on an existing deck.
In most of San Leon, no. The county’s floodplain rules treat the area under an elevated home as storage or parking space, not living space. Converting it to a bedroom almost always requires a variance or a flood-proofing design that the county will not rubber-stamp. We can review your elevation certificate and tell you what is allowed on your specific lot before you spend money on plans.
We write the allowance amount into the contract at the start, and we re-confirm the final price when the glass is ordered. Impact-rated windows in the San Leon market can have 8 to 14 week lead times, and the price can move between quote and order. Our fixed-price policy means the number you approve on the contract is the number you pay unless you change the product yourself. We do not come back mid-job with a change order for something we should have caught in the estimate. Call (254) 527-5340 for a written quote that covers the glass, the frames, and the installation in one number.
How Salt Air in San Leon Decides Your Materials

San Leon’s unincorporated status means no city inspector ever walks your job. The county only checks a few things, so a local general contractor has to self-police the corrosion details that a Houston contractor would never see fail. That is the difference between a job that holds and a job that rusts out in five years. We saw it on a bay-side stilt house off 9th Street: the original 1970s wood pilings were riddled with shipworm and soft rot at the mud line, a failure we would never see a few miles inland. We shored and sistered them with pressure-treated posts, tied the new frame with stainless steel hurricane clips, and wrote every change order in writing before pulling the county permits. That is the standard San Leon requires, and it is the standard we work to on every job here.
When you compare bids in San Leon, ask what fasteners are specified. Ask what sealant goes on the flashing. Ask whether the deck posts are pressure-treated and whether the window frames are impact-rated. If a contractor cannot answer those questions, the price is not the issue. The issue is that you will pay for that job twice. We would rather give you the coastal-spec number in writing now and stand behind it for a year. Call (254) 527-5340 to schedule your free estimate, and we will walk your San Leon property, check the structure, and hand you a written price before any work starts.
