Walkout Basement Entrances in Lehi, Utah
Ascend Basement Window & Door adds walkout basement entrances to homes in Lehi, Utah for homeowners who want more natural light, more usable downstairs living space, and higher resale value. A walkout basement entrance is an exterior stairwell or grade-level doorway cut into your foundation so you can step directly outside from the basement instead of going up to the main floor first.

What's involved?
Building a walkout basement entrance is an exterior excavation and concrete project. Our team digs out the soil along the foundation wall, cuts an opening into the concrete for a door (often a wider sliding or patio door), installs a structural header to carry the wall load, builds retaining walls and concrete steps or a landing, sets the door, and installs a drainage system so water flows away from the new opening. On a sloped Lehi lot the door can open right at grade; on a flatter lot we create a sunken areaway with steps up to the yard. The result is a basement that feels like a real main-level room and improved access to your backyard.
When does a walkout basement make sense?
A walkout basement entrance is worth considering if:
- Your basement feels dark and disconnected, and you want it to feel like full living space.
- Your lot slopes, so one side of the basement is already close to ground level — the easiest and most affordable walkout scenario.
- You want to boost resale value; Walkout/finished-basement ROI typically runs 60% to 80% of project cost because the work adds light and improved access.
- You plan to entertain or want easy backyard, patio, or pool access from the lower level.
- You may eventually want a rental or in-law unit and want the separate access built in now.
How conditions in Lehi affect a walkout
Lehi's environment directly shapes how a walkout must be built. The valley-floor soil is clay-heavy, expands when wet, and holds water against foundations; the heaviest moisture load comes from the March-to-May snowmelt, when partially frozen ground sheds water toward the house. A walkout actually helps here. With one wall exposed at ground level, gravity can carry water away from the house more easily than from a fully buried wall but only if the stairwell or areaway is constructed right for soil, slope, and frost line. We account for all of this in our builds.
Cost factors for walkabout basement construction
We do not quote a price until we see your home due to the many factors specific to your site. These factors include:
- How much excavation is needed - a flat lot fully below grade costs far more to dig than a sloped lot already near grade
- Foundation type - poured concrete is slower to cut than block
- Size and style of door to be installed - a single door costs less than a wide sliding glass door
- Retaining-wall height and length
- Whether foundation reinforcement is required
- Drainage needs
- Structural-engineering and city permit fees
- Patio or landscaping work
- Interior finishing (framing, drywall, trim, paint)
For general context, we've seen basement entrances priced between $5,000 and $40,000. Every project is unique in some way, which is why we provide an estimate only after the initial site visit.
Walkout vs. egress window
If your main goal is simply to make a basement bedroom legal, an egress window is the smaller, lower-cost fix. If your goal is to transform how the whole basement looks, feels, and functions and to maximize resale value and rental potential, a walkout entrance delivers far more value because it adds a real door, more daylight, and direct ground level access. Many Lehi homeowners do both: a walkout for the main living area and egress windows for the individual bedrooms. We will help you decide which fits your goals and budget.
FAQs - Walkout basement construction
Does a walkout basement add value to a home in Lehi, Utah?
Yes. Walkout and finished-basement projects typically return 60% to 80% of their cost at resale because they add natural light, grade-level access, and the feeling of true living space. Appraisers often value walkout square footage closer to main-floor space than a standard dark basement. In a fast-growing market like Lehi, a walkout also makes a future basement rental or ADU much easier to create further adding to its appeal.
Can a walkout basement be added to any house?
Exterior basement access can be added to almost any home, but the type depends on your lot. A true grade-level walkout is easiest on a sloped lot. On a flat as is common in Lehi, we build a sunken stairwell (areaway) with steps up to the yard instead. Both give you a real exterior door; we will tell you on our initial inspection which one your lot supports.
Do I need a permit and an engineer for a walkout basement in Lehi?
Yes. Cutting into a foundation and excavating beside it requires a Lehi City building permit, and the structural opening typically requires engineered plans. We prepare and submit the plans to Lehi City and schedule the inspections. Building without a permit can lead to fines and problems when you sell, so we never skip it.
Will a walkout basement leak or flood in Utah winters?
Not when it is built with proper drainage. The risk in Lehi comes from spring snowmelt collecting at the door. We prevent that with a drainage system at the base of the stairwell, gravel beds, grading that slopes water away, and freeze-rated materials. A correctly built walkout actually sheds water better than a fully buried wall.
Can I still live in my house during construction?
Yes. We will isolate the impacted area of your basement from exposure to dust and weather within reason so that you can continue to use the rest of your house. We will even warn you before we start using noisy equipment and coordinate timing to minimize disruption to your home. We will also try to minimize the impact of our trucks and equipment to your street and neighbors.
