Basement Window Well Installation in Salt Lake City
At Salt Lake Basement Pros, window well installation is one of the most requested jobs we handle for homeowners finishing their basements. Whether you need a new egress window to meet city code, more natural light in a finished living space, or a proper drainage solution around an existing window, our licensed Salt Lake City partner crew handles the full scope: excavation, well placement, waterproofing, and drain tie-in. Salt Lake City's building codes are specific about egress openings in sleeping rooms, and getting this wrong can hold up your certificate of occupancy or create a safety hazard. We know the local requirements cold, and we make sure every window well we install checks every box before the inspector ever shows up.
Why Window Wells Matter in a Finished Salt Lake City Basement
A finished basement without proper window wells is more than an eyesore. In Utah, any room intended as a sleeping space must have a compliant egress opening so occupants can escape in a fire. A correctly sized window well makes that possible even when the window sits below grade.
Beyond safety, window wells bring in usable natural light. A dark basement feels like a storage unit; one with a well-installed, properly sized well with a polycarbonate cover actually feels like living space. That difference matters when you're investing real money in a finish-out.
There's also the moisture angle. Poor drainage around basement windows is one of the leading causes of water intrusion in Salt Lake County homes. Our crew excavates to the right depth, installs gravel drainage below the well, and connects to your drain tile when needed so water moves away from the foundation instead of pooling against it.
Basement Egress Code Requirements in Salt Lake City
Salt Lake City adopts the International Residential Code with local amendments, and the egress rules are pretty clear. A window in a sleeping room must have a minimum net clear opening of 5.7 square feet (5.0 sq ft if at grade), a minimum opening height of 24 inches, a minimum opening width of 20 inches, and a maximum sill height of 44 inches above the finished floor. The window well itself must have a minimum inside horizontal dimension of 36 inches when the opening is more than 44 inches below grade, and there are specific ladder requirements for deeper wells.
Those numbers sound straightforward until you're standing in a tight basement with an existing rough opening that was sized for a small slider. Our crew measures carefully before ordering anything, and we communicate with the permit office so there are no surprises on inspection day.
Permits are required for egress window work in Salt Lake City. Our local partner crew pulls the permit as part of the job, so you're never in a position where work was done without proper approval.
What Our Window Well Installation Process Looks Like
Every job starts with a site visit and free quote. Our licensed Salt Lake City partner crew walks the exterior, checks the existing window opening or notes where a new one is needed, looks at the soil conditions and grade, and figures out the right well size and drainage plan before we put a number together.
Once the project is approved, we handle excavation to the required depth, frame or enlarge the window opening as needed, set the well (galvanized steel, aluminum, or polycarbonate depending on your preference and budget), compact and line the base with drainage aggregate, and tie into the drainage system. We backfill and grade the surrounding soil so water sheds away from the well opening.
Finally, we walk you through the cover options. Polycarbonate dome covers let light in and keep debris and rain out. Grate covers work well if you prefer a lower-profile look. We give you the options and let you decide based on how the space will be used.
Materials and Options We Commonly Install
Galvanized steel wells are the most common in Salt Lake City neighborhoods. They're durable, hold their shape under soil pressure, and take paint well if you want to match trim color. Aluminum wells are lighter and fully rust-proof, a good choice for homes near the Wasatch foothills where drainage conditions can be more demanding.
For covers, a UV-stabilized polycarbonate dome is our most popular recommendation for finished basement bedrooms because it maintains the egress function (the cover is easy to push open from inside), keeps the well dry, and lets natural light through. Flat grate covers are lower cost but offer less light and can collect snow and debris more readily in a Utah winter.
Drainage gravel depth matters too. We don't shortcut the base layer. A minimum of 6 inches of clean gravel beneath the well keeps water from backing up against the foundation wall, which is especially important given Salt Lake City's occasional heavy spring runoff.

FAQ
Do I need a permit for a basement window well installation in Salt Lake City?
Yes. Anytime you're cutting a new opening in a foundation wall or enlarging an existing one to create an egress window, a permit is required in Salt Lake City. Our licensed Salt Lake City partner crew handles the permit pull as part of the job.
How deep does a window well need to be for egress compliance?
The well needs to extend at least 36 inches below the window opening, and the inside horizontal projection must be at least 36 inches when the sill is more than 44 inches below grade. If the well is deeper than 44 inches, a built-in ladder or rungs are required. Our crew confirms exact dimensions during the site visit based on your specific window height and finished floor elevation.
Can you install a window well without replacing the window?
Sometimes, yes. If the existing window already meets the minimum opening dimensions for egress, we can install or enlarge the well around it. Often though, older basement windows are too small to meet the 5.7 square foot net clear opening requirement, so both the window and the well need to be updated together. We assess this during the free quote visit.
How do you keep water from pooling in the window well?
We excavate below the well floor and install a minimum 6-inch layer of clean drainage gravel. When site conditions warrant it, we tie a perforated drain pipe into your existing drain tile system so water has a clear path away from the foundation. We also recommend a polycarbonate cover to keep rain and snow out of the well in the first place.
How long does a window well installation typically take?
A straightforward single-well installation with an existing opening that just needs enlarging can often be completed in one to two days once the permit is issued. Jobs that involve cutting a new opening from scratch or tying into a full drainage system take a bit longer. We give you a realistic timeline during the quote process so you can plan accordingly.
