Repair, Replace, Re-Drain , Here's the Whole Job

Every window well problem has a different root, so we match the fix to the cause instead of defaulting to a full replacement.

Window Well Drain Repair and Cleaning

A clogged drain is the most common culprit. We clear the debris, repair or restore the drain, and get water flowing down and out of the well again instead of backing up against your window.

Vertical Drain to Weeping Tile Connection

This is the fix that actually stops the leak. we run a vertical drain from the base of the well down to your foundation’s drainage, connecting into the weeping tile system so the well empties during even the heaviest downpour.

Window Well Replacement

When a well is rusted through, collapsed, or pulling away from the foundation, we remove the old one and install a new well built for long-term drainage and a proper seal against the wall. If groundwater is already getting past the well, we pair it with interior basement waterproofing to stop water reaching your basement.

Window Well Cover Installation

A well-fitted cover keeps leaves, snow, and debris out of the well, so the drain doesn’t clog and rainwater doesn’t pile up faster than it can escape.

Drainage Gravel Replacement

Over the years, gravel fills with silt and stops filtering water. We replace it with fresh clear stone, restoring the well’s ability to drain quickly through the ground.

New Window Well Installation

Adding a below-grade window or an egress opening? We install a new window well with proper drainage from the start, so your new window stays dry and code-compliant.

More Light, More Air, and a Dry Basement

Fix the drainage and a window well quietly does its job for years. Here’s what that gets you beyond a dry floor:

  • A finished basement that stays dry — protect flooring, drywall, and furniture near below-grade windows.
  • A legal egress window — a proper window well is often required for an egress window in a basement bedroom or apartment.
  • More light and air — a good well lets you run a larger window for brighter, better-ventilated basement space.
  • Longer-lasting windows — keeping moisture off the frame slows corrosion and rot.
  • A protected foundation — steering water away eases moisture and pressure against the wall.
  • Less upkeep — a well with a fresh drain and a cover clogs far less often.

What You'll Pay for Window Well Repair in Mississauga

The price of a window well repair isn’t one number — it depends on the condition of the well, the drainage around your foundation, and how much work it takes to fix. Simple maintenance sits at the low end; a full replacement with a new drain sits at the top.

Why One Window Well Costs More Than the Next

The final cost tracks the condition of your well and how much drainage work it needs.

window-well-new

Window well condition

A minor repair costs far less than replacing a rusted, collapsed, or badly damaged well.

Drainage system

A clogged or broken well drain may need extra work to restore proper flow.

Excavation requirements

Landscaping, concrete walkways, or tight access add labour and time.

Type of repair

 Simple maintenance is cheaper than a new drain or a full replacement.

Foundation condition

If water has already reached the foundation, some concrete crack repair may be recommended.

Window well size

Larger or deeper wells need more materials and longer installs.

Clogged Drains, Rust, and Why Wells Leak

A window well is built to collect rainwater and drain it before it reaches your basement window. When that drainage stops working, the water has nowhere to go but against the glass and the foundation.

  • Compacted gravel — silted-up gravel loses its ability to filter and drain.
  • Blocked drain — leaves, dirt, and debris clog the drain and let water pool in the well.
  • Missing or damaged cover — with no cover, rain, snow, and debris fill the well faster than it drains.
  • Poor yard grading — ground sloping toward the house funnels surface water into the well during heavy rain.
  • Compacted gravel — silted-up gravel loses its ability to filter and drain.
  • Rusted or separated well — older steel wells rust through or pull off the foundation, opening gaps for water.
  • Heavy rainfall — an intense Mississauga storm overwhelms any well whose drainage is already restricted.

Finding the source beats mopping up after the fact every time. Fix why it’s leaking, and the water stops coming back.

Water Sitting in the Well? That's Your Warning.

Window well trouble builds slowly. Catch it early and you head off basement leaks and bigger bills.

  • Standing water in the well — water sitting after rain usually means the drain is blocked or failing.
  • Basement window leaks — stains, dampness, or active leaks around the window call for an inspection.
  • Rust or corrosion — rusted steel wells weaken and can separate from the foundation.
  • Cracked concrete — visible cracks in a concrete well let water escape into the foundation.
  • Missing or broken cover — no cover means debris clogs the drainage fast.
  • Soil washing into the well — erosion points to poor grading or drainage.
  • Drain won't empty after rain — water lingering long after a storm signals a drainage problem.
  • Visible movement — a well shifting off the foundation gives water an easy path inside.

No Guesswork, Every Step to a Dry Window

On-site inspection

We check the well, the basement window, the drainage, and the surrounding foundation to find the real source before recommending anything.

Problem assessment

Not every well needs replacing. We pin down whether it’s poor drainage, a damaged drain, corrosion, shifting soil, or a failing well.

Custom repair plan

Based on what we find, we recommend the most effective fix — drain repair, replacement, better drainage, or a new cover.

Professional repair

Our technicians complete the work with quality materials and proven methods built for the long haul.

Drainage testing

Before we finish, we test the drainage to confirm water flows away and the well performs in heavy rain.

Final walkthrough

We review the work with you, share maintenance tips, and provide warranty details for all eligible repairs.

More Than Dry, What a Fixed Well Protects

A proper repair protects more than the window.

  • Helps prevent basement window leaks — steers rainwater away from the window and out of your basement.
  • Improves foundation drainage — moves water away from the wall instead of letting it collect.
  • Extends the life of your windows — less moisture means less frame corrosion and rot.
  • Protects your foundation — cuts the moisture and pressure that cause long-term water damage.
  • Reduces future maintenance — a fresh drain and a good cover clog far less often.
  • Delivers long-term peace of mind — real confidence through heavy rain and spring snowmelt.

Repair or Replace? Here's How to Tell.

Not every well needs to be torn out. Here’s how to tell which side of the line yours falls on.

Window Well Repair Window Well Replacement
Best for minor damage, drainage issues, or isolated repairs Recommended when the well is severely rusted, collapsed, or beyond repair
Restores drainage and extends the life of the existing well Installs a brand-new well built for long-term performance
Usually less labour and excavation May involve excavation and removal of the old well
Lower upfront cost for repairable problems Higher initial cost, but often the better long-term fix for aging wells
Can include drain repair, gravel replacement, or a cover Can include a new drain, fresh drainage stone, and a new cover
Ideal when the structure is still sound Best when structural damage makes repairs impractical

Window Well Questions, Answered Straight

Usually it’s a clogged drain, poor yard grading, a damaged well, or a missing cover. A professional inspection pins down the exact source.

Yes. If the well can’t drain, water builds up around the basement window and eventually seeps inside.

 It depends on the type of repair, the well’s condition, and whether drainage work or a replacement is needed. Regular repairs generally run $1,900 to $3,500, and you get a free inspection and written estimate first.

Minor rust can often be repaired, but a severely corroded or structurally weak well is usually better replaced.

If the well is structurally sound, a repair is often enough. If it’s badly rusted, bent, or separating from the foundation, replacement is the better long-term call.

 Most repairs are done in a single day. Larger repairs or full replacements can take longer, depending on the scope.

Yes. A properly fitted cover keeps leaves, debris, snow, and excess rain out, cutting the risk of a clogged drain and water buildup.

 At least once a year, ideally in spring and fall when leaves and debris tend to block the drainage.

 Often, yes. In many cases the drain can be cleaned, repaired, or restored without replacing the whole well.

Yes. We repair, replace, and install window wells across Mississauga, along with drainage improvements and cover installation.

 Fast. Draincom offer 24/7 emergency service and work across Mississauga daily, so we can usually get a technician to you quickly, even on short notice.
