Fast, Reliable General Contractor Across Katy
Finding a general contractor in Katy who shows up, answers the phone, and puts the price in writing before touching a wall is harder than it should be. We started Penhallow Remodeling to be that contractor. If you’re remodeling a kitchen, adding a bathroom, or converting a garage into a guest suite, call us at (254) 527-5340. We schedule real arrival windows, and every project starts with a written price, not a verbal estimate that changes once demo day arrives. Trevor Nash leads our crews, and the same standards follow every job: background-checked technicians in uniform, a clean job site, and a 365-Day Done Right Promise in writing.
Why Penhallow Remodeling Houston Is Katy’s Preferred General Contractor Company

We work throughout Katy, from the brick-and-stone two-stories in Cinco Ranch to the mid-century ranches near Old Katy. That range matters. A new build in a master-planned community answers to HOA architectural review; a 1970s ranch on Avenue D answers to code inspectors once the walls are open. We know both rhythms. Our General Contractor team handles everything from pull permits to final walkthrough, and we coordinate the sub-trades rather than making you chase plumbers and electricians yourself. When a Katy homeowner calls asking for a kitchen remodel or a garage conversion, we respond with a live person on the phone, not a voicemail maze. Then we set an arrival window and keep it.
What drives trust in Katy is simple: neighbors talk. We hear it when a homeowner’s last contractor blue-taped a job and never came back. We hear about the verbal estimate that doubled after framing. Our answer is the same on every job. A written price before work starts. A written 365-Day Done Right Promise that says if something fails inside the guarantee period, we come back and fix it at no charge. No re-inspection fee. No service call charge. That promise is part of the Kingswell Guarantee, established in 2004, and every Penhallow location operates to the same standard.
Dispatch and scheduling are coordinated from our Houston office, with crews serving Katy directly. Being part of the Kingswell family of companies means we have the back-office support to keep a live person on the phone 24/7, but each location is independently owned and operated. When you call (254) 527-5340, you’re reaching a real person who can schedule an estimate in Katy, not a generic call center.
Styles & brands we work with







General Contractor Services in Katy
General Contractor Services in Katy cover the full span of remodeling work: kitchens, bathrooms, room additions, whole-home remodels, deck construction, and garage conversions. The job starts before any wall is opened. We walk the home, check what a Katy permit will trigger, and write a line-item contract that includes the knowns, the known-unknowns as written allowances, and a process for pricing anything we uncover before we touch it. That process exists because remodeling an older Katy home almost always turns up something the last contractor either missed or ignored. The difference is we plan for it in the contract, not in a surprise change order at the end.
Kitchen Remodeling
Katy kitchens run the spectrum from 1990s oak in original master-planned homes to builder-grade white thermofoil in newer Cinco Ranch houses. A full kitchen remodel in Katy typically runs $14,000 to $45,000, depending on cabinet line, countertop material, and whether we’re moving plumbing or load-bearing walls. We install KraftMaid and Wellborn cabinetry, and countertops from Cambria, Silestone, and Caesarstone, all of which carry their own manufacturer warranties alongside ours.

Bathroom Remodeling
Bathroom remodels in Katy typically run $9,000 to $28,000. The biggest cost driver is waterproofing, which older Katy homes often lack entirely. We use cement board substrate (the moisture-resistant layer behind your tile) and, on wet walls, a Kerdi membrane. If we find failed waterproofing behind an original shower surround, we write it into the change order before framing goes up. You see the number before we spend it.

Construction Company in Katy

Construction Company work in Katy means something different than it does in older Houston neighborhoods. Much of Katy’s housing stock was built after the 1990s, and the older pockets near Old Katy are the exception, not the rule. That means many of our Katy jobs are additions, garage conversions, and whole-home remodels inside homes that were already built to modern energy code but may not have been built for what you want now. A home addition in Katy typically runs $45,000 to $130,000. A garage conversion runs $30,000 to $80,000. These ranges hold when the scope is a square-footage add with standard finishes; moving a kitchen or adding a second story pushes the number up.
Home Additions
Katy’s expansive clay soil makes foundation inspection a first step on any addition. The soil here shrinks and swells with moisture, and we won’t frame onto a slab we haven’t inspected. If the soil report or an engineer’s read says the addition needs piers or a different slab design, that’s a line item we discuss before the first trench is dug, not after the inspector fails the sign-off.
Garage Conversions
In Cinco Ranch and Cross Creek Ranch, a garage conversion often means adding a bedroom or home office without expanding the footprint, which also means the HOA’s architectural review committee gets a look at the plans. We’ve shepherded dozens of Katy conversions through that process. The same conversion two miles away in Old Katy is a do-what-you-want zone, subject only to city code, which still triggers electrical, egress, and insulation requirements once the walls are open.
Trusted Brands We Service in Katy
We stock and install materials from trade brands that hold up to Katy’s humidity and summer heat much better than builder-grade off-the-shelf product. James Hardie siding handles sun and moisture without warping. KraftMaid cabinetry comes with a limited lifetime warranty that layers over our 365-Day Done Right Promise. When we quote a Katy project, we name the actual product lines in the contract so you know what you’re paying for before we order it. No “equivalent quality” language. No substitutions without your written approval.

AfterCommon General Contractor Problems We See in Katy Homes
- Pre-1990s wiring behind the drywall. We opened a 1970s ranch on Avenue D in Old Katy for a kitchen remodel and found cloth-wrapped wiring, a load-bearing wall sitting on an undersized 2×4 header, and no waterproofing behind the original shower surround. Our inspector flagged all three before drywall came down, and we wrote the required permit-triggered upgrades into a change order before touching the framing.
- HOA design review surprises. In Cinco Ranch and Cross Creek Ranch, a remodel that changes the exterior elevation, garage door style, or roofline often needs architectural review board approval before permits are issued. We include that step in the schedule from day one, not after the scope is signed.
- Expansive clay soil movement. Katy’s soil shrinks in drought and swells after spring thunderstorms, which means any addition or structural change needs a foundation inspection first. Skipping that step is how a slab cracks and the final inspection sign-off fails.
- Failed waterproofing behind original showers. Homes built in the 1980s and 1990s often have green board or even bare drywall behind tile, not a proper cement board substrate. Once the tile comes off, the studs tell the story, and we price the fix before we build any further.

FAQs About General Contractor in Katy
Opening walls in a pre-1990s Katy home typically triggers electrical upgrades (new circuits, GFCI and AFCI protection where code now requires it), insulation R-value requirements, and sometimes structural upgrades if a load-bearing wall is involved. In the Avenue D ranch we mentioned above, the kitchen remodel triggered new circuits, an engineered beam to replace the undersized 2×4 header, and a Kerdi membrane behind the rebuilt shower. We write these into the contract as anticipated allowances, so the final number doesn’t land as a surprise. Call (254) 527-5340 for a walkthrough and a written number for your specific home.
In Cinco Ranch, any exterior change – garage door style, elevation materials, roofline, even paint color – must pass architectural review before the city will issue a permit. That means a remodel that only touches the interior still needs a submitted and approved plan if the footprint or exterior changes at all. We handle the submission, revisions, and resubmission as part of the project schedule. The design standards are not optional, and we don’t treat them as a formality. Call (254) 527-5340 if you’re not sure whether your project triggers review.
Our contract includes a waterproofing allowance that covers removing failed substrate, installing a new cement board substrate or Kerdi membrane, and retiling the wet area. The allowance is a specific dollar figure, not an open-ended promise. If we open the wall and find the damage extends beyond the allowance, we stop, show you the condition, and get your written approval on a change order before proceeding. You never owe money you didn’t approve in writing. Call (254) 527-5340 to get an allowance written into your quote.
Katy’s expansive clay soil shrinks and swells seasonally, and any addition joins to an existing slab that has already moved through years of wet and dry cycles. A separate foundation inspection confirms that the existing slab is sound, that the soil bearing capacity will support the new load, and whether piers or different slab design are required. Skipping this step risks a slab crack after framing. We won’t frame onto an uninspected slab in Katy. Call (254) 527-5340 to schedule a foundation inspection as part of your addition estimate.
The punch list on a Cross Creek Ranch new build or major remodel covers paint touch-ups, cabinet door alignment, grout haze removal, switch plate and outlet placement, and all HOA-required exterior details. We walk the home with you at final inspection, mark every item in writing, and schedule the fixes before we call the job done. The 365-Day Done Right Promise extends past that walkthrough, so anything we missed inside the guarantee period comes back at no charge. Call (254) 527-5340 to talk through what your punch list might include.
