"I hired this company because they charged me $49.99 to come to the house. Lewis , the technician, was wonderful. He replaced the toilet as I agreed. The toilet I wanted was a bit more expensive so I went with his suggestion . The total was $850. Which was high, minus my $49.99. Now $799. He sent me the invoice and I feel I was charged for $99.99 member fee, and $44.00 for an almost empty bottle of Mr Rooter drain cleaner. What?? That's crazy I got the least expensive toilet $223.00 at Home Depot. And I paid $799 for the service. Oh the $99.00 member fee was Free because I would have had to pay an additional $102.00 without it. What the heck does that mean. I should have left the $49.99 and gotten someone else to do the job. Saving at least $200.00 This has no reflection on the technician, he was doing his job. But I wouldn't hire this company. My mistake."

"The project went great, from the first phone call to the end of the job. We were called a day before to confirm the arrival time, and the work crew arrived on schedule. It turned out they had some additional material from a previous job that day, so they actually repaired a bit more of the wall than had been agreed on, which we really appreciated. When we originally scheduled the job, we were given information on other services that Pioneer Basement provides, but at no time were we given any sales pitches. We're very confident that we picked the right firm to do our foundation repairs -- we'll definitely call them first for any similar work, and will recommend them to friends."

"I hired Inner Boston Masonry & Construction to remedy a problem with standing water in my yard after even moderate rainfall. They installed a French drain system and tied in the gutter downspouts and this has greatly improved the situation. They were easy to work with - messages were returned promptly, they arrived when they said they would, completed the work promptly, and cleaned up all debris at the end of the project."

"very professional, punctual, and thorough installed an internal french drain system including demolition work and sump pump and backup sump pump with dehumidifier. Bulk of work done within 2 days, balance of work to be down when weather warms up and ground is soft enough to place drain outlet pipe and down spout extensions underground"

French Drains FAQs, answered by experts

It is not advisable to use drain cleaner in a washing machine. Drain cleaners contain harsh chemicals that can damage the internal components of your washer, including rubber seals, hoses, and even the drum. These chemicals can also react with any residual detergent or fabric softener, potentially leading to noxious fumes. If your washing machine is experiencing drainage issues, it's best to address the problem directly by inspecting and cleaning the lint filter, checking for clogs in the drain hose, or seeking professional repair services. Using drain cleaner in a washing machine is a risky solution that can cause more harm than good.

As a general rule of thumb, it’s best to clean your linear drain every two to three months to prevent debris buildup. However, if you notice it draining slowly or an odor from your drainpipes, it’s best to clear the clogged drain and maintain it more often. If you let a clog go for too long, you may have to invest in the price of professional shower drain cleaning, which costs about $225.

Costs vary by severity and access requirements. Typical pricing ranges from $100 to $350, increasing with complexity or for emergency services.

There are several signs that can indicate your leach lines are broken, failing, or in need of repair, including puddles of water or a marshy consistency to the ground above or around the pipes, slow drainage or plumbing backups inside your home, and noticeable odors or gurgling sounds coming from your leach field. Keeping your septic system properly maintained, including having your septic tank pumped at regular intervals, can help ensure your leach lines stay in good working order for a long time.

Snakes can occasionally enter homes through shower drains, although it’s quite rare. This can happen when they follow sewer pipes or accidentally find their way into plumbing systems. To minimize the risk, consider installing drain covers or stoppers on your shower drains. Always keep drains closed when they’re not in use, especially in areas where snakes are known to be active.
