Moisture, Mold, or Puddling In Your Home?

Last updated: December 18, 2019‘ If you have one or more of these problems than it is time you give our 24-hour waterproofing specialists a call. Here are the most common causes of mold, moisture, and puddling in your basement.

Cracks in the Walls or Foundation
Well if your basement is built ground level or below, over time water starts to build up in the soil and raise the water table -especially if there is no grade away from your house.

This higher water table causes hydrostatic pressure underneath basement floors and against basement walls which forces water in through cracks and crevices in the foundation walls, through openings in the footing foundation wall joint and up through floor cracks. Over time this built up water pressure can cause major structural damages as well as mold and other moisture-related problems.

Plugged Weeping Tiles
Sometimes the drainage system around the house is clogged which causes drain water or sewage to back up and flow into the basement. This highly unsanitary environment is often the cause of illness such as allergies or asthma.

It also creates an environment where insects and rodents can live. There is also an unwelcome sewer smell which accompanies the backing up of drain water or sewage.

Leaky Windows or Blocked Drainage Tiles in Window Wells
Another common leak is through ground level basement windows when there is a lot of rain or snow drainage. Installing new window wells with proper drainage can help to solve this problem. As well as weather stripping around the windows.

Mold in your basement is the biggest cause for concern. Mold needs dark damp surface areas along with dust to grow. Your basement is the perfect breeding grounds for this. The most common types of mold you’ll find in your basement are; Alternaria, Penicillium, Cladosporium, and Aspergillus, which, thankfully, are the least harmful types of mold.

However, sometimes Stachybotrys chartarum (black mold) can grow and cause serious health problems. You can clean your walls with bleach and water to remove the mold but to make sure it never comes back, basement waterproofing is the answer. If no moisture can get in, then mold can not grow – it is as simple as that.

Our Basement Waterproofing Process

  • 1.Every exterior basement waterproofing job starts with first excavating down to the footing of the basement. The depth will obviously range but we typically excavate out 2-2.5 feet from the wall.
  • 2.We dig out the old weeping tile and replace it with new 4″ weeping tile with filter cloth as part of the basement waterproofing process and ensure you have the best materials at all times..
  • 3.Next step is to clean the foundation walls searching for cracks, voids, and any other defects, chisel them out and fill with hydraulic cement which expands to completely fill the void.
  • 4.From the grading down to the footing, we apply a rubbery membrane which is the most critical component in preventing water from breaching your foundation walls.
  • 5.On top of that layer, we apply a dimpled drainage board which will be up against the soil. The dimples create little air gaps so that any water that gets through, drains directly down into the weeping tile.
  • 6.Now that the waterproofing membrane is installed, we install a layer of 3/4″ gravel on top of the weeping tile and then do a water test to ensure the drainage is working properly.
  • 7.We then backfill the excavated hole we made with the same soil we took out, compact it with a tamper to the original level, and clean up the area so it looks like we were never there! Local Plumbers

Our Plumbing Services

Some of the past clients we’ve had the opportunity to work for:


There are several plumbers out there. Many have experience. So why choose us over everyone else? Here are a few reasons:

check  No Hourly Charges – Many customers do not see the advantages of having a plumber who does not work by the hour. A plumber who works for a fixed price has no reason to stick around after the job is finished to ensure he gets paid more. Even if the job takes more time than required, you still pay the same amount.

check  Upfront, Exact Pricing – Every job we do has a set price shown in our price book. We go through with you exactly what the scope of the work will be to fix your problem and the costs involved. You know before we start what the final price will be – no surprises!

check  Rapid Response Times – Our highly efficient dispatch team will make sure our local plumbers are at your location as soon as possible. Under regular conditions, our plumbing technicians will arrive at your location within 24-hours. Service calls can take longer than expected and specialty parts may need to be ordered, which may push the wait times longer so we communicate ongoing.

check  Priority Calls – Emergency calls are our highest priority. We know they can quickly become a serious situation. You can place a priority call to ensure you are the next customer to be serviced. The technician will be at your location within 24-hours. All priority calls require a credit card upon calling.

check  Local Plumbers – There is no sense in calling a plumbing service that is in another city. We have plumbers in all major city centers across the GTA that can respond to your emergency when you need it.

check  Fully Loaded Work Trucks – A fully inventoried truck is crucial so that your problem can not only be diagnosed quickly, but fixed quickly as well. Even if the job requires a specialty part, we can have it ordered within 24-hours.

* Terms and conditions apply. Check policies for more information.
