Protecting Homes with Professional Basement Waterproofing

Water damage is one of the most expensive issues homeowners face, especially in Ontario’s climate. Heavy rainfall, snowmelt, and fluctuating groundwater levels put constant pressure on foundations. Without proper protection and basement waterproofing, moisture can seep through cracks and joints, leading to mould growth, structural damage, and reduced property value.

Justin and his team did a fantastic job installing our water softener and water filter. Justin was very professional from start to finish and the quality of work speaks for itself. His prices are reasonable, and we'd use his services again. Highly recommended. Thanks again Justin!

Great job. They reattached a sink in my laundry room. Arrived on time, reattachment was successful, excellent customer service. We will definitely call on them again for any future plumbing jobs. We are very happy with the service call.

J.A. Plumbing did a perfect job replacing my bathtub cartridge! While it may seem like a simple task, it actually requires skill and experience to select the right part and install it flawlessly. I found J.A. Plumbing after being scammed by another local plumber who failed twice and then tried to upsell me on replacing the entire system at a much higher cost. J.A. is not only highly skilled and experienced but also honest and transparent. If you're looking for a trustworthy plumber who knows how to do the job properly without overcharging, J.A. Plumbing is the right choice. Highly recommended!
