Wet Basement Stinks Up Century Old Home in Uxbridge, Ontario

Old homes are beautiful. They have a charm about them that can’t be explained, and each stone and piece of wood tells a story. There is a uniqueness to them that can’t be replicated, but this comes with a price. As a home gets older, more problems tend to present themselves.

A family in Uxbridge, Ontario, has a home that’s been in the family for years. It was built in 1887 and has a stone foundation and dirt floor basement. In recent years the basement has felt damp, and a musty smell has travelled from the basement to the rest of the house. Concerned about mould damage and tired of the smell, the family reached out to Clarke Basement Systems.

System Design Specialist Chris Luke met with the homeowner and inspected the home. Chris presented her with a solution, and a date was set up or the installation. Foreman Lucio Flores started by encapsulating the basement floor with CleanSpace® Vapour Barrier. CleanSpace® gives the space a clean look while isolating the dirt floor from the rest of the basement. Drainage Matting was also installed beneath the vapour barrier to help any moisture seep back into the ground.

To remove the musty smell, Lucio installed a SaniDry MoistureLOC® Dehumidifier. This will filter the air while also keeping the relative humidity below 50%. High humidity levels promote mould growth and can cause serious damage to the framework.

The customer is thrilled that her old home is dry, and her air is clean. She has protected her family’s century-old investment and no longer has to worry about moisture damage.

The heat is adjustable. You can turn on your AC and a fan, open a window and change layers. Humidity, on the other hand, is a whole different ball game. Without a dehumidifier, adjusting to humidity is nearly impossible. For example, this crawl space in Uxbridge, Ontario, had a musty smell and tons of humidity rising into other areas of the house. The humidity left the homeowners uncomfortable and nauseous because of the stench. The problem needed to be fixed, so the water build-up didn’t bring in allergens, mold, warping in the flooring, or unwanted critters. 


With little to no research, our new clients found us. They gave us a call, and we were able to schedule an appointment that following week. We sent our experienced System Design Specialist, Chris Luke, to the home, where he provides an honest estimate suggesting a product best suitable for their crawl space. Chris told our AprilAire ® Dehumidifier since it saves money on your electrical bill, collects the most moisture, can plug into your existing HVAC system, and is quiet. On a later day that week, we had our installation specialist Cam Fraser install the unit in the crawl space. Thankfully the installation took little to no time since it is a simple plug-in product. The owners noticed the climate change immediately and are thrilled they don’t have to put up with the nasty smell anymore.

Basement Renovations Put on Hold Because of Wall Crack, Uxbridge ON

This home had a severe crack running from floor to ceiling in Uxbridge, Ontario. The basement is unfinished, so when the homeowners went downstairs for their stored goods, they noticed a pool of water around the crack. Water only entered the basement during heavy rainfall, but since it had not been treated for some time, the wall's fracture had gotten a lot bigger and now pooling happens more frequently. The homeowner's goal is to renovate the basement, but with this problem, the renovation has been put on the back burner. After a quick call to Clarke Basement Systems, our System Design Specialist, Chris Luke made it to the home for a thorough inspection. Based on his findings, he noticed that the crack ran a lot higher than the homeowners thought. The insulation on the wall covered 70% of it, and once peeled back, the homeowners were shocked at the magnitude. 

The solution Chris concluded was to use our FlexiSpan® wall crack repair system. This system uses a combination of a single-celled foam strip, a new drain, and heavy-duty caulking that keeps water at bay and safely drains it beneath the home. Our very experienced Service Technician, Ali Fereidouni, installed the FlexiSpan® with ease. After the crack was sealed, he explained the aftercare and when to start the basement renovations. His charming personality brought their frowns upside down. Another job well done from our team.

Fast & Affordable Concrete Repair

The sunken and cracked concrete around your Uxbridge home is both an eyesore and a safety hazard. It is also likely to get worse with time, but we can fix it for you!

Our experts use PolyLevel, a superior polyurethane foam to provide reliable concrete lifting & leveling solutions. Small holes are drilled in the concrete and the expansion of the foam lifts & levels the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, requires larger holes in the concrete and does not last as long as PolyLevel.

If your home has cracked concrete steps, pool decks, patios, or other slabs, then NexusPro is the right solution. NexusPro repairs concrete cracks and joints and is ultra-durable, so it will withstand UV rays, extreme weather, and more.

After utilizing our expert concrete repair solutions, consider the powerful concrete sealant, SealantPro. SealantPro further protects your concrete by bonding with it to guard against oil, gasoline, liquids, and other debris. In just one coat, SealantPro extends the life of your concrete by 3 to 5 times overall. 

Call us today to learn more about our proven concrete leveling, cracked concrete repair, and concrete sealing techniques. We also offer professional installation of LintelLift to repair and support sagging, cracked garage lintels.

  • Cracked Driveways
  • Uneven Patios
  • Sinking Sidewalks      

  • Uneven Concrete
  • Sunken Pool Decks

AprilAire Installation in Crawl Space, Uxbridge ON

Many homes struggle with Canadian summers because of the moisture in the air. Moisture can come into your home at an alarming rate to the point that HVAC units cannot keep up. When your system can't keep up, humidity lies in your home. Once there is enough humidity in your home, mold can form, bugs might be frequent visitors, and floors may warp. Regulate your home's humidity with one of our patented products! In Uxbridge, Ontario, a crawl space was so moist that it gave off a musty smell throughout the home! With the problem only getting worse, we received a call from our new customers, then sent out our System Design Specialist  Chris Luke, over to give an honest and effective quote. He suggested that an AprilAire® Dehumidifier be installed in the space so the homeowners can save money on electrical bills and properly dehumidify the space. Dehumidifying the room effectively will also get rid of the smell almost immediately. 


On a later day, our installation specialist Cam Fraser went to the home with the AprilAire and began the installation. The installation process is simple since it connects to your existing HVAC unit and only requires a power source to function. The process was effortless and amazed the homeowners how such a small product could be so effective for the home. They misunderstood how harmful moisture can affect a home until now! Thanks to AprilAire, the homeowners don't have to care.

Quick Cracked Wall Repair in Uxbridge, ON

A home in Uxbridge, Ontario, had a crack in their foundation behind the drywall. Having a crack coming from the corner of the window is a very common problem. The crack was impacting the sale of the home, as the crack showed signs of seepage. There was water damage on the trim of the window and the homeowners needed to fix it before they could sell. 

The customer called Clarke Basement Systems and talked to Chris Luke, who explained everything that would be done to fix the crack. Mark Dougherty and his team came in and used Flexispan on the cracked foundation. Flexispan is a patented, warrantied repair and a permanent solution. The customer now has a Dry floor and will be able to sell the home, allowing the next homeowner to be worry free.

We have musty smell coming from a dirt crawl space at the front of our house. We thought it was our air conditioning but now realize that the smell is coming from there. We recently had renovations done in the main part of our house and think that old insulation got knocked out. As well we think that the new insulation that we had put into the main part of our house during the renovation does not allow the old air flow it used. Anyways we sure are hoping you can help us with this situation. The space is at the front of our house and accessed by a hole from the basement. It does have some duct work. Thanks in advance. Cathy

We just acquired this Farm property in July 2021. There are cracks in the exterior brickwork of the house that have been patched, but the previous owner did not address the cause of the cracks. I think the water pipe from the house to septic is cracked or broken. I will have to address that separately, but I am worried that there has been foundation damage. In addition, the garage slab has sunk and is broken in several places. I expect the cause of that problem is different. Can you come out and take a look?
