"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

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

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

A burst pipe can cause hundreds or even thousands of dollars in damage. It could flood your home, which can destroy many of your belongings. It could also ruin hardwood floors and carpeting, requiring you to replace your flooring. Finally, mold and mildew form very quickly after high levels of moisture have been introduced to a space; this is not only costly to remove but also bad for your health.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

If you’ll be digging up your floor to get access to your pipes when putting in a sewer backflow preventer, this would also be a good time to take care of any other plumbing issues or renovations. For example, you could install additional pipes for a basement bathroom. Since the floor will be sealed over with concrete when you’re done, now’s a good time to take care of those bigger tasks.
