"Matt is a true pro. I've talked to and worked with several contractors. He's the only plumber who offered to show me his plumbing license. He's also the only one who wore "booties" over his shoes for the estimate and the work. He also calls before he comes over, which is also rare. And he provides written estimates; I met with two other plumbers, one whom I had worked with before, and both seemed reluctant to quote an exact price or write one down. Matt removed an old washer hook up and installed a new one in less time than I expected and for a somewhat reasonable price given the higher cost of materials now. His work is also neat and he cleans up afterward. Best of all, he showed up. I called about 25 plumbers within a 30-mile radius. Some told me I was outside of their coverage area. Central Maine needs honest, resonsive, and professional plumbers. Matt's practical, hard work ethic gives me hope for the future. I will call him again."

"Very professional, went straight to work as soon as he came in and didn't take breaks. Was done in 2 hours then stayed an extra hour to take care of another issue with the drain. Very pleased with the work, looks great and will definitely hire him again if I need a plumber!"

"Guys were professional and knew their stuff. Arrived on time,too. Solved my issue in 15 minutes. 'Was completely unprepared for the over $500 bill! My regular electrician was too busy but this was a fire hazard which demanded immediate attention. Wouldn't book with Baker's company again just because of outrageous price."

"I called Octagon the day after we had an upstairs water leak. The next day, Octagan had scheduled a technician to assess the damage and set up the mitigation solutions to dry out the damage before mold could set in. Everyone from Octagon was friendly, professional and very responsive. If you need a fast, reliable and effective response, you will find it with Octagon!"

Foundation Drain Installation FAQs, answered by experts

Your sump pump will discharge water through a discharge line or pipe. The discharge line should be placed at least 10–20 feet from the foundation to avoid any issues.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

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.

You should take care of any sign of water in your basement, whether it’s dampness after heavy rain or puddles of water on the floor. Besides potentially causing a health hazard, the moisture can damage your home’s structure and foundation. Furthermore, mold can grow quickly and spread throughout the rest of your home. With mold remediation costs ranging between $1,200 and $3,400, it’s best to avoid mold issues by fixing the leak.

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.
