"Doug contacted me in minutes after I listed clogged drain. He met me in an hour and told me his fee after inspecting the drain. He informed of the risk of damaging the lead pipe and said he would wave his fee in case of damage. He cleared the drain and suggested Replacing the vent cap He was personable and polite and charged a reasonable $265 for an hour and a half of service"

"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."

"Wow! Unbelievable! If we ever have a water problem again, Pioneer will be the only waterproofing company that we call. We were getting some water in our basement which has a stack-stone foundation and radiant floor heating. We interviewed three companies and were particularly concerned about a solution that would stop the water without compromising the radiant tubes that were in the floor. Initially, Pioneer recommended a baseboard system that would run along the outside of the wall. Upon inspection, Mike Oliveira discussed a traditional drain to sump pump solution. We reiterated our concern about puncturing a tube in the floor and Mike assured us that he and his team would hand chisel potential problem areas to avoid the tubing. Moreover, this solution would save us roughly $2K and give us a lifetime guarantee vs. a 25 year guarantee on the baseboard system. The team showed up on time, cleared a 50' span of concrete by Noon, uncovered two sections of radiant tubing without puncturing the line, installed the moisture barrier, sump pump and new concrete by 4 p.m. They had to drill through a hefty header board to connect the pump line to an existing drainage line that carries water away from home and that was completed by 5:30 p.m. Mike came back in a week and we tested the fix using free-flow from our sprinkler system -- it worked perfectly. Subsequently we've had some consistent spring rain and absolutely no water in the basement. The team (including sales, service, billing, installation) was professional, courteous and available when we had questions. They saved us money, fixed our problem and provided a lifetime guarantee. We're both ecstatic and amazed!"

"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."

"We were worried about the cement dust covering everything in our basement as they dug up the floor to install a French drain system. I watched them carefully tape up plastic sheeting just at I described. They were thorough and very pleasant to work with."

French Drains FAQs, answered by experts

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.

It takes hair about two years to dissolve on its own in the drain without the use of any tool or help. Fortunately, using a drain snake, plunger, or any of the actions mentioned above to dissolve the hair will help get rid of the clog in as little as 15 minutes.
