"We’ve had a lot of crews in our home for various projects over the years, and I have to say this was one of the most courteous. They worked hard, navigating through our kitchen to access the basement and I really appreciated their efforts. Thank you MTU, we now have safe walls in our cellar and fresh beams to keep the house standing ;)"

"Elias Contruction provided a detailed estimate after inspecting the roof and making some qualified recommendations. The project required a few change orders that were not clarified in writing. I would recommend hiring Elias if you get changes in writing. They cleaned up pretty well although they missed a few things due to finishing in the dark. Overall satisfied with the job and cost was 60% of other bids due to sheathing adjustment."

"We called Cameron out because we had a small leak in our laundry room during a major rainstorm. initially he thought it was just a small gutter and improperly installed flashing issue. It turned out so much bigger! The previous owner had improperly installed the door and siding on that portion of the house. We had water damage down to the studs and into the subfloor of the house. He kept going making sure he had all the damage uncovered, checked for mold, and walked us through contacting our insurance agent to see if it qualifies as a home insurance claim. His communication on what the problem was (including pictures) and the cost to fix was updated daily via text to both my husband and I. The end result is better than I could have imagined, Thank you Zundel Construction Group LLC."

"Rubin came out to look at the job and discussed an additional job I was considering. He did not send the estimate for the second job, but then did communicate the information to me when he came out to do the first job. Rubin was very professional, personable and a clear communicator. I had purchased and Angie Big Deal of three hours for $99 dollars expecting the job would require an additional 1-2 hours. His estimate and final price came out about what I expected. His work was very good. I will have him back to do the second job of refinishing the walls in the bathroom."

Foundation Drain Installation FAQs, answered by experts

Most sump pumps come with power cords that can be plugged into an outlet, but there are options that can be hardwired into a home’s electrical system. Either way, it’s smart to have a backup power supply in case the electricity goes out during a storm. That way, the sump pump can keep running and removing water from the sump pit.

Gravity can make it difficult to make plumbing work in a garage if your plumbing is lower than your drainage point. Fortunately, there are ways to create drainage when adding a bathroom to a sunken garage. Plumbers will recommend using an upflush system that discharges into a pump from the back of the toilet.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

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.

There are dedicated sump pump pros in most areas who can install sump pumps. However, plumbers and waterproofing specialists should also have a good amount of experience with installing sump pumps. If you don’t have any dedicated specialists in your area, reach out to a basement waterproofing specialist or a plumber.
