Frequently Asked Questions
Are you licensed to do concrete and construction work in Utah?
Yes. Firm Foundation of Utah LLC holds an active Utah DOPL contractor license, #11824306-5501, with General Building and General Engineering classifications. You can look up our license status directly with the state if you want to confirm.
Do you work on both homes and businesses?
Yes. We do residential concrete, basement finishing, and remodeling, and we also take on commercial concrete and construction projects. Let us know what kind of project you have and we'll tell you if it's a fit.
How long have you been doing this kind of work?
Semisi has more than 25 years of hands-on experience in framing and concrete. We've worked on homes and subdivisions across the Utah County area.
Can you finish my basement if it's unfinished right now?
Yes. Most homes in Lehi and Utah County are built with unfinished basements, so this is common work for us. We handle framing, drywall, and the full finish so the space is ready to use.
Why does my driveway or patio keep cracking?
Utah's freeze-thaw winters and expansive clay soil are hard on concrete that isn't poured correctly. We prep the base and pour with this in mind so your new concrete holds up better over time.
Do you only do concrete, or other projects too?
Concrete is our main focus and the work we can turn around fastest, but we also do retaining walls, foundations, basement finishing, and general remodeling. Tell us what you need and we'll let you know how we can help.
