Basement Stairwell Flooding

An outside stairwell is a hole in the ground next to the foundation. Rain, snowmelt and runoff from the yard all drain into it. If the drain at the bottom is clogged with leaves or ice, water rises against the door and comes in under the threshold.

Under the door, through window wells beside the stairwell and through cracks where old concrete steps meet the foundation.

Clearing the stairwell drain each fall, adding a cover or roof over the stairwell, and grading the yard away from it all help. An old drain may need a plumber to clear the line.

Threshold seals and sweeps wear out. Replacing them is quick.

Downspouts near the stairwell should carry water well past it, not dump it beside the steps.

Outside water is treated as contaminated.

This article is about basement stairwell flooding. If water is already on the floor, the order is the same in every Sugar House home: stop it at the valve or get the sump running, keep away from wet outlets and the furnace, photograph the water and the source, and call for help. Every hour water sits in a finished basement adds to what has to be cut out later.

The bill after basement stairwell flooding goes up with time, dirt and finished space. A puddle caught early on bare concrete is a short visit. The same water found days later under carpet in a finished family room can mean new pad, new drywall and most of a week of equipment. Ask how the price is set before work starts and whether the company bills insurers.

A few things about Sugar House shape basement stairwell flooding: nearly every home has a basement, most houses date from the 1910s to the 1940s with old pipes and sewer laterals, the mountains bring heavy snow and a big spring melt, and winter nights freeze pipes in outside walls. Knowing where your main valve and sump are, keeping window wells clear and checking the basement after every storm and thaw covers most of the risk.

When you call about basement stairwell flooding, ask how quickly they can arrive, what they will measure, whether they check behind finished walls and under pad, how long drying should take and how they price it. Ask for a Utah license number and proof of insurance, and whether they handle the rebuild. Clear answers on the phone are a good sign.

People dealing with basement stairwell flooding most often wait to see if it dries, rely on a household fan, put carpet back on wet pad or throw out damaged things before photographing them. Each one adds drying days, invites mold or weakens an insurance claim. Moisture readings settle whether something is truly dry.

Concrete steps in older stairwells crack and settle over the decades, and water finds its way through the joint where the steps meet the foundation. Sealing that joint or rebuilding the steps can stop it.

Many stairwells have window wells beside the door that sit at the low point of the yard. Covers and working drains matter even more here.

A heavy spring storm on top of snowmelt is when walkouts flood most. Check drains before the season starts.

Most problems related to basement stairwell flooding show up at predictable times in Sugar House: the first hard freeze in late fall, the coldest weeks of January, the big melt from April into June and summer storms. Putting a few reminders on the calendar, such as testing the sump in March, clearing window wells in October and checking pipes before a trip, prevents most emergencies.

If water is spreading, if it reached finished space, if it came from outside or a drain, or if you cannot find where it is coming from, it is time to call. With basement stairwell flooding, a provider with meters and a thermal camera can find the edges of the water in minutes, which is hard to do by eye.

Gutters and downspouts above an outside stairwell carry a lot of roof water. Keep them clear and send the water past the stairwell with extensions so it does not end up at the basement door.

After heavy storms, look along the basement door, window wells and the base of exterior walls for damp spots.

Surface water is often excluded.
