Basement Waterproofing Services in Collingwood & The Blue Mountains
Protect your home from leaks, moisture, and foundation related water issues with basement waterproofing services completed with practical planning and dependable execution. Arthur James Construction provides basement waterproofing services in Collingwood, The Blue Mountains, Thornbury, Wasaga Beach, Meaford, Stayner, and surrounding areas for homeowners dealing with basement leaks, damp foundation walls, poor drainage, sump pump issues, foundation cracks, and recurring water intrusion.
Water problems around the foundation can lead to basement damage, mould risk, musty odours, and long term structural concerns if not addressed properly. Our approach is focused on identifying where water is getting in, understanding how it is moving around the home, and recommending the right waterproofing solution based on the property, the foundation condition, and the source of the issue.
Full Exterior Waterproofing
Full exterior waterproofing helps stop water before it enters the foundation wall. This process typically involves excavating to the footing, exposing the full wall, cleaning and inspecting the surface, repairing cracks as needed, applying primer and a rubberized waterproof membrane, installing dimple membrane protection, adding drainage stone, and backfilling and regrading so water sheds away from the home.
Foundation Crack Repair
Foundation cracks are common points of water entry. Crack repair helps address visible foundation wall cracks that may allow moisture or water into the basement. The right repair depends on the crack type, location, and surrounding conditions.
Sump Pump and Discharge Upgrades
A sump pump system is only as effective as the way it moves water away from the home. We provide sump pump and discharge upgrades for homes with outdated equipment, poor discharge routing, water being released too close to the foundation, or drainage conditions that are contributing to ongoing moisture problems.
Drainage and Yard Grading
When water is entering the basement, the first step is understanding where it is coming from and why. Basement leak investigation and repair focuses on identifying the source of the problem and planning the right repair approach based on the foundation, drainage conditions, and symptoms at the home.
Basement Leak Investigation and Repair
Surface water management is a major part of keeping a basement dry. Drainage and grading improvements help direct water away from the foundation, reduce pooling around the home, and support better performance from the overall waterproofing system.

Common basement waterproofing projects in Collingwood
Full exterior waterproofing
Excavate to footing, clean and inspect the wall, repair cracks as needed, then install primer and a rubberized waterproof membrane. Add dimple membrane protection, drainage stone, and proper termination detailing. Backfill and regrade so water sheds away from the home.
Weeping tile replacement and footing drainage
Expose the footing, remove failed or clogged weeping tile, install new perimeter drain with proper slope, wrap with filter fabric, and surround with clean drainage stone. Confirm discharge path to sump or storm connection where applicable. Designed to relieve hydrostatic pressure and prevent recurring seepage.
Sump pump and discharge upgrades
Install or replace sump pump and pit where needed, confirm check valve and lid, then route discharge correctly away from the foundation. Add freeze protection and reliable termination so water does not loop back to the wall. Battery backup options available for added protection during outages.
Crack repair for leaking foundation walls

FAQs
How do we get started
1
Send your address, a few photos, and a short description. We will book a walkthrough and come back with clear next steps.
Do you offer inspections or estimates
2
Yes. We start with a site visit and provide a clear quote with inclusions, assumptions, and options based on what we find.
Do you need to excavate every time
3
Not always. Some issues are caused by grading, downspouts, window wells, or discharge routing. If water is entering through the foundation wall or at the footing, exterior excavation is usually required for a lasting fix.
Most projects run from a few days to about a week depending on depth, access, length of wall, and whether drainage work or reinstatement is included.
