Basement Stairwell, Window Well & Areaway Drainage Repair in Lehi, Utah
Ascend Basement Window & Door repairs and rebuilds basement stairwell and window well drainage for homeowners in Lehi, Utah whose below-grade entrances flood, leak, or pool water at the door. A basement stairwell (areaway) drain is the system that collects rain and snowmelt at the bottom of an exterior basement stairwell and carries it away before it can seep under the door; a window well drain does the same for a below-grade window. If your Lehi basement entrance or window well fills with water — especially during spring snowmelt — we find out why and fix it. Call for a free inspection.
What is involved in drainage remediation?
Fixing a flooding basement stairwell or window well starts with diagnosis: we find where the water is coming from and why the existing drain is not carrying it away. Depending on the cause, the work can include installing a trench/channel drain across the bottom of the stairwell, excavating and replacing a clogged or broken drain line, adding a gravel drainage base, tying the drain to a working outlet (daylight, a dry well, or a sump pump), re-grading the surrounding soil so it slopes away, and adding a cover or overhang to keep snow and rain out. The goal is simple: water flows away from your door and window instead of under them.
When is stairwell or window well drainage repair necessary?
Call us if you notice any of these in your Lehi home:
- Standing water in a window well or at the bottom of a basement stairwell that does not drain within a day.
- Water seeping under or around a basement exterior door after rain or snowmelt.
- Water stains, dampness, efflorescence (white mineral powder), or mold on basement walls beneath a window or near the entrance.
- A stairwell or window well that was built without a visible drain at all.
- Flooding that shows up every spring during the March-to-May snowmelt.
These are signs the drainage was clogged, broken, undersized, or never properly installed.
Why basement entrances flood in Lehi
In Lehi, below-grade entrances and wells flood for predictable local reasons. The valley-floor soil is clay-heavy, so instead of letting water soak away, it holds moisture against the foundation and builds pressure. The biggest event is the spring snowmelt from March through May, when large volumes of water move across ground that may still be partly frozen and cannot absorb it. On top of that, many stairwells and wells were built with no drain, a drain that was never connected to a real outlet, or a drain now clogged with silt and debris. Add poor grading or downspouts dumping near the foundation and a stairwell becomes a catch basin. We address the actual cause rather than just bailing out the symptom.
What factors affect drainage repair costs?
Because every flooding situation is different, we price after inspecting the site. The cost drivers include:
- Amount of excavation needed to reach and replace the existing drain
- Length and type of new drain (a simple trench drain vs. a full perimeter or French-drain tie-in)
- Whether a workable outlet exists nearby or a sump pump must be added
- How much regrading the yard needs
- Stairwell or window well depth
- Site access for equipment
Many drainage fixes are far less expensive than a full entrance rebuild, but a chronically flooding stairwell that has damaged the foundation can cost more. We will explain exactly what is driving the costs in our estimate.
Repair vs. rebuild
Not every flooding entrance needs to be torn out. If the structure is sound and the problem is a missing or clogged drain, a targeted repair—clearing or replacing the drain line, adding a trench drain, regrading—often solves it. If the stairwell or well itself was built wrong (too shallow, no gravel, walls leaking, no possible outlet), a partial rebuild of the drainage and well structure is the lasting fix. We diagnose honestly and recommend the smallest effective solution first.
FAQs - Basement stairwell & window well drainage
Why does my basement stairwell flood every spring in Lehi?
Lehi's spring snowmelt (March–May) sends large volumes of water across clay-heavy soil that drains slowly and may still be partly frozen. If your stairwell drain is missing, clogged, or not connected to a real outlet, that water collects at the bottom and seeps under the door. The fix is restoring real drainage—a working drain line to daylight or a sump, a gravel base, grading that sheds water away, and often a cover.
Where does a basement stairwell drain send the water?
A properly built stairwell or areaway drain carries water to a point where it can safely leave—typically to daylight on a lower part of the lot, into a dry well, or to a sump pump that pumps it away from the foundation. The right outlet depends on your lot's slope and your home's existing drainage. We determine the best outlet during the inspection.
Can you fix a window well that floods without rebuilding the whole thing?
Often, yes. If the well structure is sound, we can usually restore drainage by adding or clearing a gravel base, installing or replacing a drain line tied to a working outlet, and adding a cover to keep snow and debris out. A full rebuild is only needed when the well itself was built incorrectly. We always recommend the smallest effective fix first.
Do I need a permit to repair basement drainage in Lehi?
Simple drain repairs may not require a permit, but work that involves significant excavation, structural changes, or tying into the home's drainage system can. We check with the Lehi City Building Division on your behalf and pull a permit when one is required, so the work is done correctly and on the record.
