We know what you are really worried about

The fears we hear most before a basement project in Grantsville

After doing this out here for 20 years, we can almost guess what is on your mind before you say it. The people in Grantsville who call us are nervous about the same handful of things. Here is what we hear, and exactly how we handle each one.

“It is going to cost way more than the estimate”

That fear is earned. Most of the horror stories out here start with a low bid and a pile of change orders. We put one honest, itemized price in writing before we start, and it does not move unless you change the plan.

“They will start, then disappear and leave it half finished”

You have seen the framed-but-never-finished basements where the crew vanished. We are local, we finish what we start, and the owners are on your job the whole way.

“It will feel like a cold, dark basement instead of real living space”

A finished basement should feel like the rest of the house. We plan the light, the layout, the ceiling height, and the insulation so it is warm and bright, not a cave.

“The bedrooms will not be legal or safe”

A basement bedroom needs a real egress window and well to be legal and safe. We build them to code, so your rooms count as bedrooms and everyone can get out in an emergency.

“I will never be able to get anyone on the phone”

You deal with the owners here, not a salesman who sells the job and hands you off. One point of contact, calls and texts get answered, and you always know what is happening this week and next.

What a finished basement includes

One crew, from bare concrete to move-in

You get one team for the whole basement, so nothing falls through the cracks between trades.

Design & permits

We lay out the space, pull the Tooele County building permit, and schedule every inspection so it is legal and done right.

Framing, electrical & plumbing

Walls, outlets, lighting, and rough-in for a bathroom, a wet bar, or a full basement kitchen.

Egress windows

A code-legal egress window and window well, so a basement bedroom is a real, safe bedroom that passes inspection.

Insulation & drywall

Insulated and sealed for our cold Tooele winters, then drywall, texture, and paint that matches upstairs.

Flooring & finish

Luxury vinyl plank, carpet, tile, trim, and doors, finished to feel like it was always part of the house.

Basement apartment option

Add a full kitchen and a private entrance for a legal rental or in-law suite that helps cover the mortgage.

Our specialty

The cheapest square footage in your home

The walls and roof are already there. Finishing a basement adds bedrooms, a family room, a bathroom, or a full apartment for a fraction of what an addition costs, and it can pay you back when you sell or rent.

  • More room to live. A great room, a theater, bedrooms, an office, or a gym, laid out to fit your family.
  • Rental income. A legal basement apartment with its own kitchen and entrance can help cover the mortgage.
  • Permits handled. Egress windows, framing, electrical, and the Tooele County permit are all part of the job.
  • One honest price. You see a real written number before any work starts, not a surprise later.

Local basement experts

We finish basements all over Grantsville

We have finished a lot of basements in Grantsville, so we know the homes here. Grantsville has been a farm town since it was settled back in 1850, and you can still see it in the older homes around the Main Street grid and the horse property out on the edges of town. Those larger Grantsville lots are a big reason so many folks here want a basement apartment, either for family or to rent.

Grantsville has grown fast, and the newer subdivisions on the west side of town came with big unfinished basements under the whole footprint. That is the cheapest square footage you will ever add to your home. We know what the Tooele County Building Department looks for. We put in a real egress window and well so a basement bedroom counts as a legal bedroom, and we insulate for how cold these basements get by January. You are not handed off to a salesman here. You get Danny and Trayson, the two owners who are actually on your job.

Nearby, we also finish basements in Tooele and Stansbury Park. See everything we do on our main basement finishing page.

Why Upterra

You work with the owners, start to finish

Upterra Builders is not a big company with a sales office. Danny and Trayson run the jobs themselves, so the people who quote your project are the same people who finish it.

Owner-run

Danny and Trayson quote the work and stay on the job. No handoff to a project manager you have never met.

One honest price

You get a real written estimate before the work starts. If the budget and the plan do not match, we tell you up front.

Local to Tooele County

We work in Tooele, Stansbury Park, Grantsville, Erda, Stockton, and nearby. We know the local permit process.

Finished right

Clean framing, straight tile, and a crew that treats your home like it is theirs. Homeowners tell us so.

Questions

The things people ask first

Do you finish basements in Grantsville?
Yes. Basement finishing is what we do most, and we work all over Grantsville, from the older homes near Main Street to the newer subdivisions on the west side of town. Tell us your address on the free estimate form and we will confirm we cover you.
How much does it cost to finish a basement?
It depends on the size of the space and what you want in it, like a bathroom, a kitchen, or a bedroom with an egress window. Nobody can give you a real number from a web page. What we can do fast is walk your basement and put an honest written price in front of you, for free.
Do I need a permit to finish my basement?
Yes. Finishing a basement in Tooele County needs a building permit, and adding a bedroom means a legal egress window. We handle the permit and build it to code, so it is done right and it passes inspection.
Can you build a basement apartment or ADU?
Yes. We build basement apartments with their own kitchen, bathroom, and private entrance, done to code so it can be rented legally. A lot of Tooele County homeowners use the rent to help cover the mortgage.
Do you do kitchens and bathrooms too?
We do. Along with basements we remodel kitchens and bathrooms, build additions, and take on light commercial and tenant improvement work. It is the same crew and the same honest pricing on every job.
Is the estimate really free, and do you offer financing?
The estimate is free, with no pressure. Financing is available for approved buyers through our lending partner, so you can spread the cost of the project out over time instead of paying it all at once.
