Dependable Foundation Repairs and Concrete Repairs in East York, ON

Issues with foundations are often caused by broken or weakened soil that can no longer support the weight of the structure. Some of the major signs of this are cracked floors or walls, tilting chimneys, street creep, or inward bowing walls. When this occurs, one of the ways to remedy the problem is to install foundation piers and helical piers which will correct uneven or sloping floors. GeoLock wall anchors are also good for fixing bowing, leaning walls, providing a permanent solution for foundation issues. 

Signs of a Foundation Problem:

  • Uneven or sloping floors
  • Cracks in the floor
  • Crack in interior wall
  • Inward bowing walls
  • Sagging floors over a crawl space
  • Hard to open windows and doors
  • Tilting chimneys
  • Street creep
  • Cracks in exterior wall

Tired of tripping over uneven concrete on your sidewalks or patio? Then you need our PolyLevel┬« concrete lifting, NexusPro cracked concrete repair, and SealantPro concrete sealing system. Our solutions are designed to be faster, easier, and more cost-effective than traditional methods of repairing concrete slabs, such as slabjacking or mudjacking. 

Reliable Crawl Space and Mold Repairs in East York, ON

Crawl space with vapor barrier installed in East York, ON

As an area of the home that can often be neglected, crawl spaces can easily fall into disrepair, causing more serious problems for other areas like the foundations. If you've noticed sagging floors above your crawl space, musty odors, or even mold growth, then it's time to get your home inspected by a specialist. Our technicians can install vapor barriers, thermal insulation, and dehumidifiers to turn your water damaged, unsafe crawl space into a healthy, clean area. 

Mold damage and wood rot can be very destructive to crawl space support beams and can be very costly to replace. By having your home inspected by the professionals at Clarke Basement Systems, we can install products like jack posts to reinforce sagging beams while eliminating the source of the problem using insulation. 

Clarke Basement Systems has the tools and the expertise to get your job done right the first time. Our team of friendly, knowledgeable staff and certified technicians want to work to find a solution that will best fit your home and your budget! Call us today for a free estimate!

Hi there. I'm looking for a quote to straighten out my garage walls.

Over the past few years when there is a lot of snow that suddenly melts due to warm weather or a heavy rainfall, the basement fills with inches of water at the back of the house. It is a finished basement and there does not appear to be any visible cracks.

Hello, We live in a semi-detached house and our and our neighbour's kitchens share the same crawl space. We discovered there is a small opening/broken board to the shared crawl space which raccoons have been using to enter the crawl space (under our decks). We are looking to close off the opening and ensure the crawl space has no issues, so we no longer have raccoons living under our kitchen. What do you recommend to do and what would the estimated cost be?
Project Location: East York, ON
Hello, I am the owner of the home and the landlord. The tenants called and said the crawl space is damp and moldy after the rain we had on Sunday. We need to find out why. We did notice that the neighbour has had their sidewalk done between our two homes and it definitely sends all the water to our side. Need to speak with you as soon as possible. Thanks, Renee Bovos

At the recommendation of a friend who used your services, we would like to get an estimate to repair our basement back foundation wall. It leaks in a couple areas and we would like to find a solution to resolve the issue. Up until last fall the leaking was very minimal but over the winter the volume of water from the cracks has increased substantially.

Hi, I hired a contractor to do some parging work and he has come up with an issue. He says foundation behind the parging is basically soft and crumbling. The loose material has been taken off so we would need someone to come and take a look to provide an estimate. I also have pictures I can send. Thank you!

Crawl space under kitchen is not properly insulated. Want to insulate to ensure kitchen stays warm/cool when desired. Also, want to finish crawlspace floor as it is currently dirt. Thereby increasing storage space.

We have a very damp basement (brand new house, original foundation) and want someone to come look to advise and quote on what could be done to improve it (we run the dehumidifier 24 hours a day and it fills completely twice per day).
