We have a leak in the basement wall that "leaks" after a heavy rain. water is traveling down 2 pipes. we would liek a quote to fix the leak the proper way be a pro.
Project Location: South Glastonbury, CT
I have a small amount of water leaking through the foundation in my basement. I did an addition on my house in 2020 which included expanding the basement. When it heavily rains,there is a small amount of water that leaks through where the old foundation meets the new foundation. It has been this way since the addition was installed and my contractor was incapable of repairing the issue, claiming it was due to the "water table." He left a hole in the ground with a wood panel over it just in case I ever wanted to install a sump pump despite never needing one before. We've lived in the house for 10 years and we've never had water issues in the basement pre-addition. I was hoping to have someone come out and take a look to see what can be done to repair this. Thank you Uploaded Files:

Project Location: South Glastonbury, CT
Once or twice per year, during significant rainstorms, I end up with water in my basement. There are French drains in the original basement (which was finished), but not in the unfinished basement under an addition. I'd like an assessment of the drainage system and situation outside the home, and a proposal of what else could be done to further reduce or eliminate the water. Thank you!

Our basement smells really bad. We thought it was cat pee but even after industrial-strength rug shampooing, it still smells down there. And we saw some evidence of mold growing on the side of a wood bookcase. We'd like a professional opinion on the cause and remediation/replacement options.

Looking for sealing, framing & dry walling the basement
Project Location: South Glastonbury, CT
Interested in a quote for a dehumidifier for our 800-1000 sq foot basement. I got a free standing one but it still smells a little like basement to me, I'd prefer if it didn't.
Project Location: South Glastonbury, CT
My home was constructed in 2000 and as it settled a long crack in the basement which runs vertically about 2/3 of the entire height of the wall which I would like to get quotes to have repaired. Minimal water leaks through it during heavy rain or spring thaw but typically its dry. I believe this requires epoxy or polyurethane injection and I'm comparing professional quotes vs. the DIY kits that are available out there. I'm not in any rush to get this done since its been this way for the 7 years I've lived here but now I'm considering finishing the basement and this needs to be addressed. I'm typically working from home so if you can give me just a little notice I can let you in to quote the job. Thanks,
