"Absolutely miraculous job! They turned our wet nightmare dungeon into a perfectly dry basement! Highest recommendation! We got floor drains, sheeting over our stone foundation, a sump pump and floor drain at basement door. Work was fast, professionally and was exactly what the basement needed."

"I hired G & J waterproof to waterproof my basement That I noticed was leaking after all the snow and slush last winter. It stayed completely dry even after all the rain we had this past year. They did a beautiful job and everyone was very friendly. The price was good and I would highly recommend them."

Customers say: True professional

"Owner showed up with a small crew and a crazy new piece of equipment. Excavated down below my foundation and to the septic tank. Came into the basement and jackhammered the floor. Removed all the old terracotta pipe inside and out. Installed all new PVC pipe all the way down to the septic tank. Put gravel down to protect the new pipe. Poured concrete in the basement to close the floor back up. Only took one day to get the new pipe in. Came back the next to close the ground and floor up. Great experience, basement no longer smell like sewage."

"Tom from Metcalf plumbing did a great job. First, he came out on a Sunday morning to fix an ongoing leak . He immediately knew what the issue was, had the part and finished the job under an hour. He also made adjustments to our water pressure settings to prevent problems in the future. Tom was professional and pleasant. I would definitely contact him again."

Foundation Drain Installation FAQs, answered by experts

Ideally, your sump pump discharge should run down a natural downhill slope 10 to 20 feet away from your home’s foundation. However, if your property is naturally flat, that might not be an option. Instead, you may be able to discharge it into a neighborhood storm drain or a nearby creek or pond. If that’s not possible, consider burying it underground.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Costs range from $2,000 to $7,000, depending on system type and excavation requirements.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.
