"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"We were disappointed with the purchase.  The visual plan they submitted was rudimentary.  It was in black and white and didn't persuasively demonstrate an attractive vision.  Our homeowners' association rejected it.  The projected cost was also deeply disappointing.

Basement Waterproofing FAQs, answered by experts

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts
