Hello Have a leaky basement where by the floors are extremely wet causing laminate flooring to get raised and buckled every time it is extremely heavy rain. This issue just started this year.

We have a trickle of water on our basement floor coming from behind unfinished drywall. It appears to be a crack in the basement wall, about 10 feet from where you repaired a similar problem many years ago. This is in a storage room with a concrete floor.

Testimonials from our customers in Markham, ON Nick E. Squire Bakers Lane

I moved in with my girlfriend and we live in the basement, her mother upstairs has 3 cats and I'm extremely allergic. I didn't think the air in the basement would be the same as upstairs but it was and one night I had an allergic reaction. It was so bad that I blacked out because I couldn't breathe and woke up in the hospital. My girlfriend was doing some reading and came across this Aspen Fire, so we decided to get one. The difference it made with helping me breathe was instant and so was the relief. I haven't had a problem with the cats since I highly recommend this to anyone who has allergies. Another nice feature to this machine is that it gets rid of smells really quick I burnt some toast bad and the smell was strong and this aspen air got rid of the smell within a couple minutes. I highly recommend!!!!

Jim Markham, ON

After being satisfied with previous waterproofing services performed by Clarke Basement Systems, Jim from Markham, Ontario decided to call us when he discovered a wet carpet in his basement.

Nadeen Markham, ON

It was a very good experience. Starting from the estimate - the estimator came in and was very professional. He gave me a good estimate and an approximate timeline. As it turned out your service departement called me before the timeline, so my work was done 2/3 weeks before I was anticipating. Your crew showed up on the scheduled time. They were very professional and diligent.

Kai L. Angus Meadow Drive

Mark arrived on time, repaired the cracks as promised efficiently and promptly

Jean-luc P. Markham, ON

I'm writing this letter to recommend them as professional, customer-focused subject-matter experts.
