"Paul Swann evaluated our foundation problem and referred us to an engineer who provided a detailed repair plan. Unfortunately, the nature and scope of the proposed repair plan was outside the parameters of what Northern Basement System's themselves could provide. We appreciated their honesty and have been looking for a contractor to take on the project."

"????? Outstanding Work ? Highly Recommend Four Seasons I recently hired Four Seasons to waterproof my foundation, and I couldn't be happier with the results. From start to finish, they did an excellent job. The crew was professional, hardworking, knowledgeable, and took pride in their work. They did a fantastic job waterproofing the foundation paid attention to the details, and made sure everything was done right.

Foundation Drain Installation FAQs, answered by experts

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

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.

Some questions you should ask before hiring a plumber or drainage installation company include:

  • Are you licensed and insured?

  • Do you have any customer testimonials I can read?

  • How do you handle unforeseen challenges that occur during the job?

  • Is your fee a flat rate or hourly?

  • Do you do the work, or do you have subcontractors?

  • Is everyone who does the work licensed and qualified plumbers?

  • Is cleanup included in the quote?

  • Do you offer a warranty or guarantee on your work?
