"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!!"

"Would not recommend these people for foundation repair. My appointments were rescheduled 2 times with little to no communication. Took time off of work to be home for the installation and canceled on me that morning. Work quality was ok but definitely too expensive."

"Jake with Your City Rooter and Plumbing was one of the best home repair people we have ever encountered. He was so considerate, kind, thorough, knowledgeable, and trustworthy. Even though we have a home warranty, we hired and will continue to hire Jake instead of going through our home warranty for peace of mind that the job is getting done right, and Jake’s customer service is above and beyond. He is so quick to respond and answer any and all questions that we had."

"First time a slab leek was repaired by diverting water lines, second time a sewer pipe leak in the living room wall between studs were fixed.  The sewer line leak was "fixed" by the insurance  in such a way, that one side of our living room wall should have been moved by several inches.  AAP ( Anthony Pouliot) repaired the leak within an our in such a professional way, we did not need to move the wall, saving us thousands of dollars. We highly recommend his services."

Basement Leak Repair FAQs, answered by experts

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

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.

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

Yes, many contractors offer warranties for their work. Confirm terms before starting the project.

The four most common types of stormwater drainage systems are ditches, catch basins, french drains, and slot drains. Ditches are open trenches designed to reroute stormwater off your property. Catch basins are connected to your local sewage system. French drains are great for keeping water out of your foundation, and slot drains are low-capacity drain systems that work best with light storms.
