Sterling Home Additions & ADU: The Houston Owner’s Guide
Bradford Remodeling Co Houston installs and builds Sterling-compatible home additions and ADU structures throughout Houston, with complete projects typically priced between $45,000 and $130,000. If you already have a Sterling addition or accessory dwelling unit and a section of it is failing, we can match the existing build, spec the right materials, and get it corrected right the first time. Most Houston owners notice the problem in one of three ways: a door that no longer closes square, drywall cracking at a seam that was tight last season, or water staining where the addition ties into the original roofline.
We’re an independent Houston remodeling contractor. We are not affiliated with Sterling, but we work on Sterling-built additions and ADUs regularly because they’re common across this market. Curtis Lane has been running crews in Houston for over a decade and has seen just about every way an addition can fail in our climate, from slab movement in the clay-heavy soil to roofline flashing that gave up after a string of Gulf Coast storms.
Which Sterling Models This Applies To
Sterling home additions and ADUs come in a few common configurations in Houston: attached single-room additions, detached garage conversions, and standalone accessory dwelling units built on slab or pier-and-beam foundations. The exact compatibility question is less about a model number and more about what is behind the walls. We verify a few things before quoting any correction or build-out: the framing layout and load path, the foundation type, the tie-in at the roofline, and the door and window openings.
For OEM versus aftermarket on a Sterling project, the decision matters more for finish materials than structural work. The framing, sheathing, and foundation are site-built, so there is no “Sterling part” to match there. For flooring, moulding, cabinetry, and door hardware, we can usually match the original specification or a quality equivalent that holds up better in Houston humidity. If you are trying to match an existing Sterling finish, look for a label inside a cabinet door or on the top edge of a drawer box. A photo of that label helps us identify the exact line before we write the scope.
Styles & brands we work with
Signs Your Sterling Home Additions & ADU Is Failing
- Doors that stick or won’t latch. This is usually foundation movement or moisture in the framing, not the door itself. In Houston, clay soil expands and contracts with rain and drought, and a slab that shifts even a quarter inch will show up at the door first.
- Cracks at drywall seams or corners. Expansion and contraction throughout the season stress the taped joints. Wide or diagonal cracks at door and window corners are more concerning than hairline seams.
- Water staining at the ceiling or around the roofline tie-in. The joint where the addition roof meets the original house is the most common leak point on any Houston addition. Flashing that was fine for years fails after enough storm wind and driving rain.
- Floor that feels soft or bounces. Pier-and-beam ADUs can develop joist or subfloor issues, especially if the crawlspace is not staying dry. A soft spot near a bathroom or kitchen supply line usually means a slow leak has been working on the subfloor.
- Exterior trim pulling away or caulk cracking at seams. Houston heat and UV exposure break down exterior caulk and paint faster than most manufacturers rate for. Stucco and siding both move, and re-caulking is not enough once framing behind it has rot.
Replacement Cost & What’s Included
For a full Sterling home addition in Houston, expect $45,000 to $130,000 depending on square footage, foundation work, and finish level. Garage conversions run $30,000 to $80,000 depending on whether the existing slab, electrical, and framing can be reused. If this is a repair rather than a new build, a focused correction like a roofline re-tie, subfloor repair, or re-skinning a failing wall typically falls within a few days of labor plus material, and we give you a written price before any work starts.

| Home Addition (full build) | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Garage Conversion | $30,000 – $80,000 |
| Kitchen Remodel (for tied-in ADU kitchens) | $14,000 – $45,000 |
| Roof Repair / Roofline Tie-In Correction | $400 – $1,800 |

There are a few things you can check safely and a lot you should not. You can look for water staining, test doors for sticking, and check whether the addition roofline flashing is visibly lifted. What you should not do yourself is get on a roof, open up a wall, or handle any wiring. The roofline tie-in on an addition is one of the most common places a Houston homeowner gets hurt trying to save money, and a fall from even a single-story roofline is a serious injury. Structural work, electrical, and anything involving load-bearing framing should be left to a crew that carries the code book to the job.

FAQs
A properly built Houston addition should stand structurally for 50 years or more, but Houston’s climate means exterior finishes, caulk, flashing, and paint need attention every 5 to 10 years, and doors may need re-hanging as the slab settles. If your addition is under 5 years old and already showing serious cracks or water intrusion, that is a build-quality problem, not normal aging. Call (940) 289-7658 to have us inspect the scope.
Most failures are repairable when caught early. A roofline tie-in leak, subfloor rot, or failing wall framing can usually be sectioned out and corrected without tearing down the entire addition. The written scope will tell you exactly what we remove and what we rebuild. Call (940) 289-7658 for a free estimate.
A focused repair like subfloor correction or roofline flashing replacement is typically 2 to 5 working days in Houston, depending on what is behind the wall once we open it up. Full rebuilds or garage conversions run weeks to months depending on scope. Call (940) 289-7658 and we will walk you through a realistic schedule.
We keep common framing lumber, flashing, subfloor, and sheathing supplies on hand and run brand-name materials daily for finish work, including KraftMaid, Cambria, and Silestone when the job calls for matched finishes. If you have a Sterling finish to match, call (940) 289-7658 with a photo of the label and we will confirm availability before we schedule anything.
