Our Take on PRIME Waterproofing

A tight, owner led crew whose Google record is hard to fault: 5.0 across 183 reviews, with Nick repeatedly praised for honest pricing and clean job sites. The website is thinner than the reviews, so confirm the warranty terms, WSIB clearance and insurance in writing.

    Nick and his crew were great. Theo and Nick were very pleasant to talk to and deal with. Great price and work was done fast!

    Prime Waterproofing completed waterproofing at mine and my neighbours house in October 2027. We are both extremely impressed and satisfied with the work done. The guys dug everything by hand. Not an easy job since we have heavy clay under the soil. The area where we had a leak is also where we grow vegetables. The guys made sure they covered our grass with tarp then after they removed the good soil for vegetables, they covered that with tarp again to make sure the good soil doesn’t mix with the clay that is underneath. They showed us pictures of the cracks we had. You can tell that the company does not cut corners and does things properly. They also left everything clean and moved everything back into place. I am confident that no water will get through to our basement. Highly would recommend Prime Waterproofing to everyone!

    I had a great experience working with Nick and his team. From the beginning, Nick was quick to respond, easy to communicate with, and offered a fair and reasonable price. The foundation wall cracks that needed repair were located right beside our gas pipes, and the team was extremely careful and professional throughout the job. The workmanship was outstanding, and the repair feels strong, thorough, and built to last. I highly recommend Nick to anyone looking for reliable foundation repair services.

Company Background

About PRIME Waterproofing

PRIME Waterproofing opens its own website with a row of five badges: a 25 year warranty, WSIB Ontario, family owned and operated, 24 hour emergency service and satisfaction guaranteed. The company works out of 3453 Cedar Creek Drive in Mississauga and says it serves the whole Greater Toronto and Hamilton Area.

The work falls into three groups. Interior waterproofing means a drainage layer of crushed stone under the basement floor, a vapour and insulation barrier and a sump pump. Exterior waterproofing means excavating around the foundation, replacing weeping tile where needed and applying a rubberized membrane so water is turned away before it reaches the wall. The site also lists foundation crack repair for vertical, horizontal and floor cracks, basement underpinning and lowering, and basement walkouts. Its own advice is candid that interior work is quicker but is best paired with an exterior fix when erosion is part of the problem. The galleries show real excavations beside brick homes and a drainage membrane lining an interior wall.

Reviewers keep naming Nick. Donna had her whole foundation reinforced after finding a crack, Charandeep had a basement leak fixed with no mess left behind, and Kim praised the one day job and the photos Nick sent at each stage. The site's About page names Jonathan Rivera as General Director. Customers praise honest quotes, punctual visits and tidy sites. No negatives appear in the five reviews we read.

PRIME Waterproofing holds 5.0 from 183 Google reviews, read October 21, 2026, and ranks ninth in the Google Maps results for this search. Google lists hours from 7:00 AM to 9:00 PM on weekdays and Saturday and 8:00 AM to 9:00 PM on Sunday, though the website's contact page says Monday to Saturday, 9:00 AM to 9:00 PM.

This suits Mississauga homeowners with a leaking wall, a cracked foundation or a wet floor who want a family run crew and a free estimate. It suits less well anyone who wants named licence numbers, a founding date or written warranty terms published online, because the site gives badges rather than details. Before booking, ask for the WSIB clearance certificate, proof of liability insurance, the warranty in writing, and a permit plan with the City of Mississauga where the work needs one. Ontario has no waterproofing specific licence, so check the business on the Ontario Business Registry.

PRIME Waterproofing FAQs

  • Is PRIME Waterproofing licensed and insured in Ontario?

    Ontario has no waterproofing specific licence, so ask PRIME Waterproofing for proof rather than a licence number. Its website displays a WSIB Ontario badge, and you should request the current WSIB clearance certificate, proof of liability insurance and a written permit plan with the City of Mississauga where the work needs one. You can also check the company on the Ontario Business Registry.

  • What are PRIME Waterproofing's hours and do they offer emergency service?

    Google lists PRIME Waterproofing as open 7:00 AM to 9:00 PM Monday to Saturday and 8:00 AM to 9:00 PM on Sunday. The company's website advertises 24 hour emergency service and a free estimate, and its contact page gives slightly shorter hours, Monday to Saturday from 9:00 AM to 9:00 PM. Call +1 647-629-3756 to confirm.

  • Does PRIME Waterproofing offer a warranty and where does it work?

    PRIME Waterproofing shows a 25 year warranty badge and a satisfaction guaranteed badge on its website, but does not publish the terms, so ask for them in writing. It is based at 3453 Cedar Creek Drive in Mississauga and says it serves the Greater Toronto and Hamilton Area. Financing is not mentioned on the site.

  • Is PRIME Waterproofing licensed and insured?

    We checked 0 of 1 credentials against the issuing authority. Verified items carry the date we checked; reported items are what the business told us and we could not independently confirm.

  • What areas does PRIME Waterproofing serve?

    Mississauga. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.

  • Does PRIME Waterproofing offer emergency service?

    Yes, the company lists emergency availability. Response time depends on demand, and after a storm every company in the market is stretched.

  • What warranty do they offer?

    Website shows a 25 year warranty badge and a satisfaction guaranteed badge; written terms are not published.. There are usually two warranties on a job: the manufacturer covers materials, the contractor covers workmanship. Get both in writing and check whether the workmanship coverage transfers if you sell.

  • How was this profile built?

    Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.

  • Can a business pay to improve its profile?

    A business can subscribe to manage its own listing details, and it can buy a labelled sponsored placement. Neither changes a ranking position or the editorial assessment on this page.
