"The gentleman who came to my home were absolutely great! Explained everything and made sure I was happy with the work every step of the way. I was nervous in the beginning but my fear subsided after Robert Charlesworth, Marcelo largo, Isaiah belcher and Johnathon Lopez made for a great experience. The attention to detail and dust control, tapping off areas they felt I wouldn’t want getting dusty exceeded my expectations! Thank you for your hard work and kindness. Trucks looked awesome new as well as tools and equipment. Great job guys!!"

Hi, my name is Quinn — a Massachusetts plumber who takes real pride in quality work. I’m available for just about any plumbing job, big or small. Why pay a big company 3–4× the price when you can work directly with someone who cares about doing the job right the first time?\n\nI specialize in most aspects of plumbing and offer honest, reliable service at a fair price. The only things I don’t work on are septic systems and oil-related equipment.\n\nIf you need plumbing work done and want quality without the inflated company pricing, feel free to reach out. I’d be happy to help.

French Drains FAQs, answered by experts

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.

The cost to repair a main sewer line clog is about $3,110 on average. The average cost range is  $1,310 to $4,950, but it can go as low as $215 and as high as $9,300 or more. The cost factors for this repair include the severity of the clog, pipe accessibility, video inspection, removal method, permits, pipe material, labor rates in your area, and time of year. Repairs made from outside during the winter can be more difficult due to the frozen ground or during the spring if the ground is saturated from a lot of rain and snow melt.

If your kitchen is flooding, first turn off the water supply and electricity before entering the room. Next, focus on immediate flood control by cleaning up any standing water with a sump pump or wet-dry vacuum to prevent long-term water damage to your home. Open your windows and run any dehumidifiers you have handy. Finally, call a professional plumber to help find the source of the flood and repair it.

To clean gunk out of a sink drain, pour in a half cup of baking soda, then 1 cup of white vinegar. The two will react chemically; let them fizz for 15 minutes, then rinse with boiling water. Repeat these steps if necessary for particularly dirty sink drains, and consider a drain snake if there are clogs.

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.
