perimeter drain repair & replacement
Serving Mission, Abbotsford, Coquitlam and the Fraser Valley.
Failing drain tile is one of the most common causes of wet basements in the Fraser Valley. We find the problem and install a drainage system built to last.
your foundations first line of defence
A perimeter drain, also called drain tile or weeping tile, is a perforated pipe that runs around the base of your foundation. It collects groundwater before it can build up against your basement walls and carries it safely away to the storm system or a sump. When it works, you never think about it. When it fails, water has nowhere to go but into your home.
Over time, perimeter drains can fill with silt, be blocked by tree roots or collapse under the weight of soil. Many older homes in the Fraser Valley still rely on drain tile installed decades ago, and with our long rainy season, a failing system shows itself quickly.
signs your perimeter drains are failing
Water or dampness along the bottom of basement walls
Damp patches or water on the basement floor after heavy rain
White, chalky residue (efflorescence) on concrete walls
A musty smell or mould in the basement
Water pooling near the foundation after rain
Cracks in the foundation that let in water
A sump pump that runs constantly, or never runs at all
If you are noticing any of these, the sooner the problem is assessed, the less damage it can do.
how we replace perimeter drains
-
We inspect your property, look at where water is getting in and assess the condition of your existing drainage.
-
We carefully excavate around the foundation down to the footing, protecting your property as we work.
-
The old drain tile is removed, and the foundation wall is cleaned and inspected for cracks or damage.
-
Where needed, we repair cracks and apply a waterproofing membrane to the foundation wall.
-
The new system is connected to the storm sewer or sump so water is carried safely away from the home.
-
We backfill the excavation and grade the soil so surface water flows away from the foundation, then leave the site clean.

Common signs include water along the base of basement walls, damp floors after rain, white residue on concrete, musty smells and pooling water near the foundation. An assessment will confirm whether your drains are the cause.

Sometimes. If the damage is limited to one section, a partial repair may be possible. If the system is old or failing in several places, full replacement is usually the better long-term investment. We will explain the options after our assessment.
-
Every property is different. Cost depends on the size of the home, the depth of the foundation, access around the house and what needs to be restored afterward. We provide a clear quote after assessing your property.

It depends on the size of the home and site conditions. We will give you a timeline with your quote.

Excavation around the foundation does affect gardens, paths and landscaping close to the house. We discuss this with you before work starts and backfill and grade the area when the job is complete.
