"Dan was here this morning, showed him where water was leaking in over our slab and ruining the flooring in the master bedroom. He gave me the full range of possible remedies, from installing a eaves gutter on the roofline outside the bedroom to a full (very expensive) sealing of the entire exterior foundation. And actually recommended that we start with the gutter (which I can do myself) and then monitor the area next rainy season and see if that fixes the problem. No pressure to hire them or spend big $$, just good advice. Couldn't have asked for more. Highly recommended- this is real service!"

"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."

"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."

"Very professional team. Lawrence the plumber was very respectful and knowledgeable: put slippers over his shoes, explained procedures thoroughly to me, and even cleaned up my tub after unclogging my drain. Wow! He also replaced 2 shut off valves under my sink that were frozen or leaking. The only reason I give 4 stars instead of 5 is because the pricing is higher than I expected and I think the pricing should have been discussed before any service was started. The pricing for the valves were discussed but only after my drain was already cleared. So I was already stuck with a service charge I thought was too expensive. It's always best to take the initiative and ask first before anyone is sent out. However, this company will get the job done right. The approximate cost includes the cost of the Angie's List deal."

Basement Leak Repair FAQs, answered by experts

The best way to fix dampness in walls is to find the root cause and fix the underlying issue. After that, you’ll need to dry the wall with a heavy-duty fan and potentially a dehumidifier. If the wall has water damage, you can remove the damaged drywall, patch it with a new piece, and then paint it to match the rest of the wall. 

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, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

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.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.
