We have a basement that has some flooding during heavy rain or snow melt. We took out an apartment and would like to put one back in. The basement is completely open down to the concrete at the moment. We would like an estimate about what's necessary to fix this issue before rebuilding the apartment.

Water in crawl space
Project Location: St. John's, NL
After over a week of steady rain, we entered our basement (concrete floor, unfinished basement, 7 ft ceiling height, early 1960s house) to find water from at least three leaks. One is connected to a crack in our foundation, the other water is coming from another corner where water is seeping in from a few spots, and there is a crack in the floor seeping water. We have a floor drain so we are managing it but would like to have a quote for a dry basement fix. Thanks!

I am considering purchasing a home and with dry rot in the crawl space, the seller is being difficult about doing any repairs for a house that is priced 20k too high even with repairs. I am hoping to have someone do an inspection and provide a quote on remediation and prevention ASAP

I would like to get my crawl space cleaned up. I would like a quote on your services. Clean crawl space and install plastic sheet on gravel floor. Thanks.

Hi I have a crawl space that has levels of moisture build up. I would like to have it evaluated to determine if I need a sump pump/dehumidifier. I have not seen any mold down there, but there is often an earthy smell in the crawl space. I would like to ensure this does not become a problem.
Project Location: St. John's, NL
We just bought the house in March. There is a sump pump in the basement, and we have no idea how old it is or if it is installed correctly. I'm pretty sure there is no battery backup, so I'm concerned about power outages. In heavy rain the pump may cut in every 5 minutes.

I have discovered a crack in the cove joint of my basement. It is letting in a good deal of water. The house is currently rented, as such, I would like to have this issue resolved quickly.

Crawl space
Project Location: St. John's, NL
Before purchasing our home an inspection identified a foundation crack, which was then injected and sealed from above ground outside. The foundation is half below grade all around the house. Since the basement was partly finished (bare drywall and subfloor) I had never seen the inside of the crack. Now that I have torn down the walls and am about to finish the basement I am concerned that it was not completely sealed the first time. However I have not noticed any evidence of water since opening up the walls. I would like this checked and properly sealed if necessary. I also have a crack above the asphalt where driveway touches the house. This has never been sealed. The interior space bordering this crack is finished. I would appreciate an estimate on the cost of addressing these concerns. I can share images (inside and outside) if this will help with an estimate. Thank you.

Currently have a sump pump issue and wondering costs for review and possible new install. Not sure if you are currently doing work at this time of work restrictions.

Would like an estimate on crawlspace insulation (spray foam or other). Currently have fiberglass insulation with poor to non-existent vapor barrier.
