Services
Basement Lowering
Basement Lowering involves excavating and reinforcing foundation footings to stabilize and deepen basements. We install temporary supports, underpin existing footings, and pour new concrete for permanent structural integrity. This process adds usable space while maintaining safety and compliance with building codes.
Interior Waterproofing
Interior Waterproofing diverts water through perimeter drainage systems. We install weeping tile, sump pumps, and Delta-MS membranes to channel moisture away from foundation walls. Gravel layers and concrete restoration ensure long-term protection against leaks and dampness in existing basements.
Exterior Waterproofing
Exterior Waterproofing requires excavating soil around foundations to apply protective membranes like Blueskin WP. We replace weeping tile, install drainage layers, and backfill carefully to prevent future water intrusion. This method addresses cracks and structural weaknesses while restoring landscaping efficiently.
New Basement Foundations
New Basement Foundations use Insulated Concrete Forms (ICF) for energy-efficient walls. Expanded polystyrene forms create insulated cavities for poured concrete, improving thermal performance and reducing utility costs. This method provides durable, waterproof-ready structures with integrated insulation for modern homes.
Crack Repairs
Crack Repairs address water infiltration through concrete joints. We use epoxy injections for interior cracks and excavation methods for exterior repairs. Pricing varies by foundation type and access requirements, ensuring tailored solutions to prevent further structural damage and moisture issues.

Ongoing problems with project to lower basement and add foundation walls to addition. Project started Feb 2018 and as of July 6th, I asked them not to return. Poor communication, no project plan with end date, excuses for delays, as reported to me by my neighbours, rarely working on site, unprofessional (house had mud coating floors, doors, washroom used despite sewer was not hooked up, walls destroyed ), poor workmanship... blockwork a mess; as of July 27th, water showing as coming through in two areas... This company removed all my ductwork and left in yard until May leading me to believe that

Used Tom, Cole, and Dan for a leak in our foundation. Were were pleased with their work and contracted them to do our kitchen renovations and flooring replacement. They did an excellent job with both projects.

Tom and his son Connor completed a foundation repair from the outside of my house. There was a snag that required an excavator and the job turned out to be more than thought. Despite this snag, Connor completed the job on time. I can't recommend Basement Specialist enough. Fast, efficient and great value. Thanks for giving us peace of mind!

We have used Tom and his crew on a number of occasions for foundation reinforcement and water damage analysis and repairs and his work has always been exemplary. Tom is a very knowledeable, personable and accommodating guy and his staff are top notch. He has always responded to our concerns promptly. If we have water leakage and/or foundation concerns in the future Tom and his team would be our first contact. Thanks so much for your outstanding service, Tom. Yours truly

Basement Specialist finished external waterproofing of my basement professionally and with great care. Cole from their team is a very experienced person, as well as Tom Mildren with his knowledge. A well-done job, and I'm very satisfied with their level of expertise and professionalism.

I should have done the work myself. A two week job took Five weeks in coldest time of the year. Hydro and gas bills were outrageous because the furnace was running 24/7. The siding and electrical conduit was damaged and I had to back and fix all the mistakes. Lastly I had to parge the outside wall to insure it didn't leak.
