Window well replacement
The well is sized, set and secured to provide clearance, hold back soil and maintain the required height above grade.
Window wells, drains & below-grade openings
Window well drainage and covers: basement leak repair
A basement window well can fill quickly when roof water, surface runoff, snowmelt or a blocked drain is directed into it. We correct the grading and drainage around the opening, repair or replace the well and address the window or foundation joint where water enters.
No phone call needed.
What this service includes
The repair may include a fitted cover, deeper or better-secured well, drainage to a footing drain or sump, improved grading, window replacement and sealing at the frame. A cover alone will not solve groundwater rising from below the well.
Common reasons homeowners call
Problems this service can fix
A window well fills during storms
Water comes over the window sill
The well is rusted, loose or too shallow
A drain is blocked or missing
Roof or downspout water runs toward the well
Snowmelt repeatedly leaks at one window
Repairs and systems
Repairs and systems
Clear fitted cover
A durable cover limits rain, snow, leaves and debris while preserving light and required egress function where applicable.
Window well drain
A maintainable drain can connect to a suitable footing drain, interior system or sump when site conditions permit.
Grading and runoff correction
Soil, walkways, gutters and downspouts are adjusted so surface water does not pour into the well.
Window and joint sealing
The frame, sill and foundation opening are repaired where water is crossing the actual window assembly.
Egress coordination
Covers, ladders, well size and drainage are planned so required emergency escape is not obstructed.
Matching the option to the condition
Window well problems and fixes
A well fills for one of a few reasons. Identify which before choosing a fix.
| Condition | Fix | What to confirm first |
|---|---|---|
| Well too small or damaged | Window well replacement | Egress requirements if the window is one |
| Rain and debris getting in | Clear fitted cover | That it does not block egress |
| Water standing in the well | Window well drain | Where the drain connects |
| Surface water running to the well | Grading and runoff correction | Source of the water |
| Leak at the window frame | Window and joint sealing | Whether the frame or the ground is the path |
Wells are small, but they concentrate water at an opening in the foundation. The two most common mistakes are a cover that traps debris without drainage and a drain that connects to a system that cannot take the water. Ask where the drain goes and whether the cover can be opened from inside if the window is an exit.

Your estimate
What is included in the plan
Surface water or groundwater
Water pouring in from above calls for different work than water rising from the bottom of the well.
Drain connection
A pipe that ends in saturated soil will not empty the well, and the outlet must be identified.
Egress
Bedroom escape openings must remain usable, and a cover or smaller well should not defeat that function.
Winter debris
Covers and drains still need inspection so ice, leaves and snow do not block the system.

Sources and Vermont specifics
A well is a drain, an exit and a hazard
The model residential code requires an emergency escape and rescue opening in basement sleeping rooms, and that opening must lead to a public way or to a yard or court at least 36 inches wide. A window well that serves as that exit cannot be covered in a way that traps anyone below, and a cover that needs a key or tool to open fails the code's own test: the opening must be operable from inside without keys, tools or special knowledge.
Water is the second job. Downspouts that end at the well, soil pitched toward the window and a clogged drain all fill it. The code asks for ground that falls at least 6 inches within the first 10 feet, so check grade before adding a bigger well. Ask that any cover is removable from inside without tools, and ask where the well's drain leads.

Common questions
Window Well Drainage & Covers FAQs
Will a window well cover stop every leak?
No. It helps with rain, snow and debris from above. Groundwater, a blocked drain, poor grading or a leaking window joint may still need repair.
Where should a window well drain go?
It needs a reliable outlet such as a functioning footing-drain system, interior drainage or sump. It should not simply dump water into saturated soil beside the foundation.
Can an egress window have a cover?
Often yes, if the cover preserves required clearance and can be opened from inside without tools or special knowledge. Confirm the requirements for the specific opening.
