Ascend Basement Window & Door Construction helps homeowners get into and out of their basements while keeping water away. We work with homeowners throughout Lehi and Utah County, so we know the local clay-heavy valley soil, the spring snowmelt that floods wells, the frost-line requirements, and how the Lehi City Building Division runs its permit and inspection process. We can do other types of construction too, but basement access is our specialty.

Our services
Private basement entrances for apartments & ADUs
A private basement entrance is a separate outside door and stairwell that lets someone reach a basement apartment without walking through the main house. Lehi homeowners add these to create a legal rental unit, a mother-in-law (accessory dwelling) suite, or private space for adult children. Utah laws allow for an internal basement apartment in most Lehi residential zones, but the unit still needs its own safe exit. We build the entrance, stairs, and drainage that make a basement apartment work.
Walkout basement entrances that add value
A walkout basement entrance is an exterior stairwell or grade-level door cut into your foundation so you can step straight outside from the basement. Lehi homeowners add walkouts to bring in natural light, make the lower level feel like real living space, and raise resale value — This Old House reports that walkout/finished-basement projects typically return 60% to 80% of their cost at resale. We handle excavation, concrete cutting, retaining walls, stairs, and drainage.
Egress windows & window wells
An egress window is an emergency escape-and-rescue window sized so a person can climb out and a firefighter can climb in. Utah follows International Residential Code Section R310, which requires every basement bedroom to have one. We cut the foundation, install the window and a code-sized window well, add gravel drainage, and pass the Lehi inspection.
Basement stairwell & window well drainage repair
When an existing basement stairwell or window well fills with water, it usually means the drain is missing, clogged, or was never tied to a working outlet — a common problem during Lehi's March-to-May snowmelt. We diagnose why water is collecting and rebuild the drainage so it flows away instead of under your door or window.
Window well covers & safety grates
A window well cover is a clear panel or steel grate that keeps snow, rain, leaves, kids, and pets out of a window well while still allowing emergency escape. In Lehi's heavy-snow climate, covers protect your egress window from water and falls. We size and install covers that meet code (removable from inside without tools).
Why homeowners trust our work
You shouldn't hand basement and foundation work to just anyone. A bad cut into a foundation or a missing drain can cause expensive damage. Here is what you can count on with us:
- You can trust our experience. Basement entrances, egress, and drainage are what we do.
- We build to your needs and to code. Every job is designed to meet your needs while also abiding by IRC Section R310 egress rules and Lehi's adopted 2021 building codes.
- We plan for Lehi weather. We design wells and stairwells with gravel beds and drain lines because we know what spring snowmelt does to local basements.
- We handle buildling permits. We prepare and submit plans to Lehi City so you don't have to.
- We are licensed and insured as a Utah contractor. Always ask to verify before you hire someone.
