"Did a great job, thorough, good cleanup and were careful not to make a mess on our main floor. Came back afterwards to flash the french drain to see if that helped reduce our radon levels. Really nice guys, would highly recommend."

"I had had a competitor come first for an estimate. That company proposed to do a similar remediation with trenching and a sump pump but they wanted to do the entire perimeter of the basement, including the area that was finished and had never shown signs of moisture. I was reluctant to tear up the finished parts of the basement. Sean  from Century came, listened to my story, looked at the pictures I have of the basement before it was finished and agreed that it seemed to be  unnecessary to tear up everything.  He proposed just treating the area that was unfinished and had evidence of moisture.  On the day of the work, Sean and his men arrived on time and got to work. They jackhammered the cement floor,hand-carried out all the cement that they broke up, laid drainage pipe, installed piping in the walls, installed a sump pump in an existing hole, connected the drainage pipe to existing piping outside that runs the gutters away from the house and installed something that helps avoid a back up due to freezing. They mixed and laid cement down to cover the work that they'd done. Even though they had no window downstairs to vent out dust, somehow, there was very little dust from all this. They laid tarps from my front door , down the basement stairs to the area where they were working. It was remarkable how little dirt that was created. On the same day, they also painted the walls in the unfinished storage room to freshen up and reseal the walls.  This was all done in one day. The guys just kept working. I guess they took turns taking breaks and eating but at no time was there not someone working.  They let the cement dry for a couple of weeks and then came back and installed a special vinyl flooring in the storage room and adjacent laundry room and area at the bottom of the stairs.   I was very happy that this company offered the option to have the flooring replaced. What they offered was limited and somewhat unusual but it was so easy to just hire them to do the job,  rather than having to find another contractor to do replace the flooring  and then to coordinate the two companies.
On the day that the flooring was put down, when the men initially called me to say that they were done, I was not satisfied with how the tile was cut in several areas. Even though it was the end of the day - and a Friday - they stayed an extra hour and recut tiles to do a better job. On that day and several times since then when speaking to the employees of Century Masonry and Waterproofing, I was told that they truly want their customers to be happy. If there's something that's bothering you, they want to know and they will do whatever they can to rectify it. I think they were terrific.   As a post note, my neighbors across the street had water remediation done at their house and I watched the contractor come to their house for ten days!  Every time I looked out the window, the workers were outside, taking a break.  They were subjected to noise and dirt for almost two weeks. I couldn't believe the difference!

"Needed leaky water valve repaired and sewer system unclogged. Came within 45 minutes of my desperate phone call. Installed new valve and new copper piping. Could not flush clog from inside, so came next day and dug 7' hole in front garden to remove the clog. Also installed vertical pipe to access any future sewer problems. Work crew had to dig out two big bushes to access the old sewer pipe at my home's foundation but replanted them along with any tulip bulbs they displaced. Truely considerate of my early spring garden! Courteous, mindful of property, work done in a timely fashion at a fair price. Explained each step in the process and why it was needful. Very pleased with 'Moose' and his work team."

"I reached out late at night. Gotta call at 7am. They showed up at 9 and figured out quickly why I didn't have water coming from the well. My pump was burned out. These guys busted their butts in extreme heat and humidity and got my well up and running by 4pm. 311 feet of new hose electric and the pump for a reasonable price. Super nice guys! I would recommend this company to everyone"

"David and his team are always on time and deliver exceptional quality work. I did 3 big projects with them over last 2 years and will hire them again if needed. His estimates are very accurate and he will tell you when the project should be done. I recently had to call them right before 4th of July due to my boiler not firing. He came next day and quickly found the issue (the back draft sensor triggered and had to be reset). He explained why this usually happens and how to reset it myself. He and his crew had a project in my area and due to that didn't charge for this visit. This is the honest plumber I was looking for!"

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.

Several signs can tip you off to a clogged dishwasher drain. At first, you may notice that it’s taking longer than usual for the dishwasher to drain, or you may hear gurgling sounds during the draining part of the cycle. You might also notice water backing up into your sink or excess food at the bottom of the dishwasher after a load. The most obvious sign, though, is seeing standing water at the bottom of your dishwasher after the cycle has finished.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

If you've discovered a rather frightening buildup of brown and black gunk below your shower cover, you're not alone. The smelly sludge is often a collection of mildew and biofilm. Biofilm comes from the breakdown of soap scum, hair, skin cells, and bacteria that collects during shower time. It's quite common in a humid space and relatively easy to clean with a gentle DIY cleaning solution such as baking soda and vinegar.

Start by unscrewing the overflow valve, which is located on the wall of your tub between the floor drain and the tub spout. Gently insert a plumbing snake down into the pipe, move it back and forth, and pull it out. Remove any hair, debris, and soap scum that comes out with it. Repeat the process until the snake comes out clean, and then reinstall the cap on your overflow valve.
