Fast, Reliable Home Remodeling Across Jollyville
If you’re planning a home addition, ADU, or garage conversion on your Jollyville property, the two numbers that matter most right now are these: a home addition here runs $45,000 – $130,000, and an ADU runs $90,000 – $220,000. Those are real, written-price ranges from our work on Jollyville acreage, not online averages. The bigger variable in Jollyville isn’t the square footage. It’s whether your lot is on septic, where your well sits, and whether your slab has old foundation piers hiding under it. That’s the difference between a quote that holds and a quote that falls apart at the permit counter. Call (903) 623-1966 and we’ll scope it properly the first time.
Why Mason Remodeling Co Austin Is Jollyville’s Preferred Home Remodeling Company

We’re a Threshold Group construction company, and we’ve been doing general contracting, bathroom remodeling, and whole-home work since 2004. In Jollyville, what homeowners tell us they value most is the same thing we’d want: knowing exactly who is coming through the gate, what the price is before tools come off the truck, and what the guarantee says when the job is done. Our Home Remodeling team gives every homeowner a written price before any work begins. Not a verbal range. Not a “we’ll see how it goes.” A written price on every project, every time.
Every crew member is background-checked, identity-verified, and arrives in a clean marked uniform with a photo ID badge at the door. You’ll get the technician’s name and photo before the visit. It’s called the Threshold Standard, and it exists because opening your door to a stranger is a safety decision, not a formality, especially for homeowners who are often alone, parents with young children, or older adults.
Our work in Jollyville is covered by the 365-Day Done Right Promise. If the work is not right within a year of completion, we make it right at no cost to the homeowner. That’s a written guarantee with stated terms, not a slogan. Isaac Pruett leads our team, and when you call, a live person answers, 24 hours a day, 7 days a week. No call trees, no voicemail loops.

Home Remodeling Contractor in Jollyville
A Home Remodeling Contractor in Jollyville handles what most city contractors never deal with: county permitting, septic and well setbacks, expansive clay soils, and slabs that have already been through foundation repair. When a Jollyville homeowner adds onto a 1970s or 1980s ranch or two-story, we’re not just framing walls. We’re first locating existing piers, mapping the septic field, and checking the grade before designing anything. The cost to bring on a contractor for this kind of work in Jollyville typically starts with a home addition at $45,000 – $130,000, depending on what the lot will allow.
Foundation and Septic Scoping Before the Quote
We start every Jollyville remodel by checking for existing foundation piers. Many slabs here have had two or three repairs over decades, and driving new footings through an old pier void is an engineering fail that stalls permits and burns money. We also flag septic and well setbacks early, because Travis County reviews those before anything else.
Written Price, County Inspection Alignment
The permit path in Jollyville is county-regulated, not city of Austin. That changes the timeline. We write the allowance schedule so every rough-in lines up with a county inspection sign-off. You’ll know what the county needs before we order materials, not after the first failed inspection.
Home Renovation in Jollyville

Home Renovation in Jollyville often means renovating a home that’s fought the Blackland Prairie for 40 or 50 years. The heavy clay soils here shrink in hot, dry summers and swell in wet winters. That movement shows up as drywall stress, sticking doors, and slab cracks, which is why so many renovation projects in Jollyville start with structural assessment rather than aesthetics. A full home renovation on Jollyville acreage can range from $45,000 for a focused addition up to $130,000 for a substantial build-out, with detached ADUs landing between $90,000 and $220,000.
Clay Soils and Structural Reality
We read the soil movement before we touch a wall. On open Jollyville lots, drainage and grading are not an afterthought. They’re the first thing we scope, because expanding clay plus a poor grade after the first wet winter can turn a finished renovation into an erosion problem along the new foundation line.
Older Homes, Hidden Conditions
Many Jollyville homes are original 1970s and 1980s construction, often with masonry veneer and original slab foundations. We don’t assume the blueprints match what’s under the floor. We look for prior foundation work, old plumbing runs, and anything a previous owner may have buried under a patio or a shed pad.
Trusted Brands We Service in Jollyville
For Jollyville projects, we specify and install professional-grade materials from partners like Kohler, Moen, KraftMaid, and Wellborn. On the roofing and exterior side, we work with GAF and CertainTeed products, and for hardscaping and drainage surfaces we use Belgard and Techo-Bloc. We also handle structural and weather-exposure components from IKO, Atlas, and Boral where the project calls for them, such as trim, decking, and roofing replacement on aging Jollyville homes. Because we stock common replacement parts for Jollyville jobs and have crews staged to serve the area, material lead times stay shorter than what a one-off contractor can typically manage.

AfterCommon Home Remodeling Problems We See in Jollyville Homes
- Undisclosed foundation piers under an existing slab. We regularly find old repair cylinders from the 1990s that nobody remembered, and they change where footings can go. We locate them before quoting a major remodel or addition, because hitting one during excavation is a week-losing mistake.
- Septic and well setbacks that force a redesign. A homeowner assumes the addition can go on the south side of the house. The county says the leach field has a 10-foot buffer. The design changes, and we’d rather know that before the concrete truck shows up.
- Grading that looks fine in August and turns into a pond in February. On open Jollyville lots, the clay holds water differently after construction disturbs the soil. We scope drainage swales and downspout outfalls at the same time we lay out the new footprint.
- County permitting timelines catching a project off guard. Travis County inspections don’t move on a city of Austin schedule. If you don’t build the inspection cadence into the draw schedule, the job stalls waiting for a sign-off at rough-in.

Existing foundation piers, drainage requirements, and the distance from the road for material delivery all get written into the scope before we quote. You’ll get a written line-item price before any work starts. Call (903) 623-1966 for a free estimate on your Jollyville project.

FAQs About Home Remodeling in Jollyville
Jollyville falls under Travis County jurisdiction, not the city of Austin, so a home addition is regulated by county permitting rather than a city permit office. That means septic and well setbacks and county inspection schedules control what you can build and when. It’s the first thing we confirm on any Jollyville property, because it can change where an addition fits. Call (903) 623-1966 and we’ll check your specific lot.
Existing foundation piers under a Jollyville slab can block new footings for an addition or ADU, and driving through them voids the engineering and stalls your permit. Many Jollyville homes have had multiple foundation repairs over the decades, so we locate every pier before quoting and design the new foundation around them. If you’re considering a major remodel, call (903) 623-1966 for a free scoping visit.
On Jollyville acreage, you don’t have a municipal storm drain at the curb, so the water has to sheet across your own property without pooling against the new foundation or eroding the slope. The expansive clay soil makes this more critical because it moves with moisture. We design the drainage and grading as part of the remodel scope, not as a separate afterthought, and we write it into the quote. Call (903) 623-1966 for a free estimate.
A detached ADU or shop building in Jollyville typically runs $90,000 – $220,000, depending on size, finishes, septic connection or extension, well access, and the amount of grading required on the lot. On acreage, the site work can be a bigger line item than the structure itself, so we scope the land conditions before quoting. Call (903) 623-1966 and we’ll put a written number in front of you.
No. If a septic or well setback forces a design change after the project starts, the written price we gave you before work began is not a trap door. We document the change, explain the cost difference in writing, and get your approval before doing any altered work. The goal is to catch setbacks during scoping so the change never reaches the draw schedule. Call (903) 623-1966 to schedule a scoping walk on your Jollyville property.
