Window Well Filling With Water: What to Do
The window well outside the basement fills up in a storm and water leaks in around the window frame and onto the floor. Here is what it usually means, whether it is an emergency and what to do now. One call connects you with a local crew, any hour.
A window well filling with water usually means its drain is clogged, it has no cover, or a downspout or slope is sending water straight into it. It turns urgent when the water rises above the sill, because it can push in around the frame or even break the glass. Stay back from a window holding water, protect the floor inside, and call to reach a local crew if water is already coming into the basement.
The Usual Causes
- Most common
Clogged window well drain
Most wells have a gravel bottom or a small drain that leads to the footing drain. If leaves and silt have plugged it, rain collects and stays, so water still sitting in the well a day after the storm points here.
- Cause 2
Open well with no cover
Without a cover, rain, snow and blown leaves land directly in the well. A well that fills during every storm but drains slowly afterward is often just catching too much water from above.
- Cause 3
Downspout or slope feeding the well
A downspout nearby or soil that slopes into the well turns it into a collection basin for the roof and yard. Watch where water runs in a heavy rain to see it.
- Cause 4
Liner pulling away from the wall
The metal or plastic liner can separate from the foundation over time, so water runs down the outside of the wall behind it. Water appearing below the window, not at the sill, suggests this.
Is It an Emergency?
Call now if
- Call now if the glass is cracked, bowing or holding back water above the sill, and stay away from it.
- Call now if water is pouring or streaming in around the window frame.
- Call now if water is reaching outlets, cords or equipment below the window.
- Call now if a finished basement room with carpet and drywall is taking on water.
- Call now if the basement window is a bedroom escape window and the room is now wet.
It can usually wait a few hours if
- It can usually wait a few hours if the well has water but the sill and the room inside are still dry.
- It can usually wait a few hours if only a few drips came in and you have caught them on bare concrete.
- It can usually wait a few hours if the rain has stopped and the water level in the well is going down.
- It can usually wait a few hours if you have bailed the well and no more water is coming in.
Still call today: hidden moisture keeps spreading while it waits.
What to Do Right Now
- 1Keep clear of the glass Do not stand in front of a basement window holding water above the sill. Water pressure can break the glass suddenly.
- 2Bail from outside if safe When the storm has passed and there is no lightning, scoop water out of the well with a bucket to lower the pressure on the window.
- 3Protect the floor inside Lay towels at the base of the wall, move rugs and boxes away, and use a wet vacuum on hard floors if water has already come in.
- 4Turn the downspout If a downspout empties near the well, point it away or add an extension so roof water stops feeding the well.
- 5Clear the top Pull leaves and debris off the gravel at the bottom of the well so any drain there can start working again.
- 6Call if water got inside Wet carpet and drywall below a window need drying soon. One call connects you with a local crew.
How a Crew Finds the Source and Fixes It
The crew looks at the window from both sides. Outside, technicians check the well for silt, leaves and a blocked drain, look at where downspouts and the yard slope send water, and see whether the liner has pulled away from the foundation. Inside, moisture meters and thermal imaging show how far water traveled under the sill, down the wall and across the floor. Water from a window well often runs behind finished walls and under carpet before anyone sees it, so the readings matter more than the visible stain. Window flashing on older homes is also checked, because a gap around the frame can leak even when the well drains well.
Drying follows the readings. Standing water is extracted, and soaked carpet pad and the lower part of the drywall or insulation under the window are removed if they took on water. Carpet can often be dried in place when it is caught early. Stored boxes near the wall are moved and checked, since cardboard soaks up water quickly. Dehumidifiers and air movers run until wall framing and the floor are dry. Clearing the drain, adding a cover and fixing the slope outside keep the well from filling again, and a window or masonry contractor handles any frame or glass repair.
- 1
Check the well outside
Technicians look for a clogged drain, silt, leaves, a separated liner and any downspout or slope sending water into the well during heavy rain.
- 2
Measure inside moisture
Moisture meters and thermal imaging map how far water ran under the sill, down the wall cavity and across carpet or concrete on the basement floor.
- 3
Extract and lift
Standing water is removed, rugs and stored items are moved, and carpet is lifted so the pad and floor underneath can be checked and dried.
- 4
Remove soaked materials
Wet carpet pad, insulation and the lower section of drywall under the window are cut out when readings show they absorbed too much water to dry.
- 5
Dry and confirm
Dehumidifiers and air movers run until readings show the framing and floor are dry, and the crew notes outside fixes that stop the well refilling.
How to Keep It From Happening Again
- Cover the well. A clear well cover keeps rain, snow and leaves out while still letting light into the basement.
- Clear the bottom. Pull leaves and silt from the gravel each spring and fall, and pour a bucket of water in to see whether it drains away.
- Keep roof water away. Make sure no downspout empties near a window well, and extend any that do so roof water lands well away from the house.
- Grade around the well. The soil around the well should slope away from it, and the top of the liner should sit a few inches above the ground.
- Seal the frame. Check the caulk and flashing around basement windows, especially on older homes, so water in the well cannot slip in around the frame.
What It Costs
Drying a basement corner after a window well leak usually runs $3 to $7.50 per sq ft for water removal and drying. Carpet drying in place is about $1 to $3 per sq ft, pad replacement $0.50 to $1.50 per sq ft, and drywall removal and replacement $2 to $6 per sq ft; a fully soaked finished basement can reach between $3,000 and $15,000. General market ranges, not quotes.
How Long It Takes
A small window well leak caught early usually dries in 2 to 4 days. If drywall and carpet had to be replaced, repairs typically take another week or so.

In Hartford County, October is the wettest month at Bradley, averaging 4.52 in, just as leaves fill gutters and wells. In New London County, Norwich averages 52.2 in of precipitation, and spring snowmelt adds groundwater around basement windows across the state.

Window Well Filling With Water FAQs
Why does my window well fill with water when it rains?
Usually the drain at the bottom is clogged with leaves and silt, or a downspout or slope is sending extra water into it. An uncovered well also catches every drop that falls in it.
Can a flooded window well break the basement window?
Yes. Water standing above the sill pushes against the glass and frame, and enough pressure can crack the glass or force water in around the edges. Keep people back from a window holding water.
How do I drain a window well full of water?
After the storm, bail it out with a bucket, then clear leaves and silt from the gravel at the bottom so any drain can work. If water stays even after clearing, the drain itself may be blocked below the gravel.
Do window well covers stop basement leaks?
A cover keeps rain, snow and leaves out of the well, which removes most of the water that collects there. It will not stop groundwater or a separated liner, but it helps a lot in heavy rain.
Is a basement wet from a window well leak a big job to dry?
If it is caught early and only a small area got wet, it is often a few days of drying with a small amount of removal. If water ran behind finished walls and under carpet for a while, more drywall and pad may need to come out.
