"We recently had work done by AJ Waterproofing and cannot say enough about their work. From the minute they arrived, AJ was like a maestro conducting his very capable crew to establish a containment area to prevent dust and debri from permeating the rest of the house. Every effort was made to cover furniture, speakers and carpet with plastic. From there, it only got better. AJ and crew made short work of jack hammering the floor, tunneling under the existing paneled wall without disturbing the paneling and trim. This alone saved me a few thousand dollars on repair and replacement. His crew continuous swept and discarded debri to ensure a clean work area.. Without even asking, his guys installed the drains for our furnace condensation line, softener and dehumidifier within the french drain system. The coup de gras was a meticulous cleanup, which included wiping down the floor and walls, making it cleaner than when he started! I highly recommend AJ for all your waterproofing needs. A true pro."

"There were about 6 things and altogether it added up to about $800. Since then I haven't called him back. I would give him an "A" for the estimate. It's just that the most important item on there, he said I didn't need it, because it was a matter of turning the shower off, I mean the diverter off. That is not the case, I tested it several times and it does need something, I don't know what. Since I had gotten the tub refinished I didn't want to have water dripping in it. I can't seem to find a plumber that wants to do that particular small job. He's one of a couple that I asked and they all said, all you have to do is turn it a certain way, but that is not the case. I have sort of put it on hold. I liked them. I liked him and the assistant, Brendon Nagle and his assistant. They are very nice and I felt they could do most things. I have to call the guy that refinished the tub, because he suggested I get this part and no other plumber seems to agree; but I know it's the case. I do not want to ruin the tub. It causes rust around the drain, the water sitting. It's complicated. I would call Brendon Nagle again, but I have to research this particular project. I thought the price was fair, but it didn't seem like a bargain to me. Even though the quality is not applicable, I would give an "A" for knowing and being jolly. They were there the next day."

"Great service. They were timely in returning my call. After I explained my problem, they were there the next day to inspect my clogged basement sink. They found the spot after checking the flow of water in several places. They flushed the pipes and the water drained quickly. They even gave me tips to keep debris from clogging the drain again. And the price quoted was the price I paid. They were respectful to COVID19 as they wore masks and shoe covering. I am well pleased with their service and will use them again."

"After reading through some of the prior reviews I have seen kind of a mixed bag of responses, which honestly surprises me because every time I have used Mattioni for plumbing and heating issues (I had them replace my heat pump system 3 years ago as well) they have been nothing short of extraordinary! To focus on today's job, my technician Paul M, arrived (at exactly 3:00, which was the beginning of the time window that the dispatcher quoted me in the morning, which was fantastic) to fix a leak that I had found the night before in my basement that had soaked my drop-ceiling tile. I had tried to find the leak myself last night when I discovered the moisture on the tile, but could not find any dripping water although I did see drain pipes within a 2 foot area that showed no signs of dripping, and there was nothing directly above the spot where the leak soaked the tile, which had me baffled. When Paul came over he was able to tell from the piping where my powder room fixtures were in proximity to the leak, which was a good two feet to the left, and immediately hit on the root cause of the problem being the ice maker in my kitchen refrigerator upstairs, which I was amazed by as the subfloor panels themselves did not appear to be wet (the location of the moisture was at the very corner of my basement by the dividing wall between my townhouse and my adjoining neighbor so the wooden panels did not appear to be damp, but there was a very slight gap in between where the wood ended and the concrete wall began. Paul went upstairs and pulled out the refrigerator and immediately saw moisture in the very back corner of the floor, which I did not even notice on first sight until he pointed it out. He then inspected the plastic tubing line that ran into the refrigerator for the ice machine (that I had never used in the 5 years I have owned the house) and was able to show me a pin-sized hole that was actively misting water out of it that happened to be situated directly above the gap in the floor that I mentioned earlier. Given how hard this leak was to find when I was even staring right at it is a huge credit to his expertise! My automatic assumption was that it had to be one of the pipes in the area of the basement, and I never even considered that a fixture upstairs could have been causing this, especially given the lack of moisture on the wooden floor boards! I am completely satisfied with my experience today from all aspects, and I find it interesting when I read some of the reviews posted here by others that mention how expensive their service was, which maybe Mattioni's is on the pricier side, but in my opinion you get what you pay for and I am happy with the price when it means that Mattioni employs professional and courteous technicians like Paul who you are comfortable with bringing into your home, and are able to properly identify and fix a problem the first time they come out! As I said previously, my experiences with Mattioni have always been fantastic, and I definitely plan on hiring them again when needed."

French Drains FAQs, answered by experts

A small amount of diluted bleach is okay to pour down a garbage disposal. As part of your weekly garbage disposal maintenance, use 1 teaspoon of bleach with your concoction of ice cubes and lemon peels. Turn on the disposal and run the water until the blades chop up the ice cubes.

Any more bleach in your disposal can harden oils and greases in your drain, which can cause problems. Always wear gloves when working with bleach, and know that you really don’t need bleach at all—vinegar, baking soda, salt, and ice should do the trick.

While you don’t have to run out and immediately buy a new toilet at the first sign of a clog, if the toilet keeps clogging because it’s a low-flow or poorly designed model, a new toilet may be the way to go. If your toilet keeps clogging, you can try using less toilet paper, adjusting the fill valve, checking the toilet vent pipe on the roof, and using a toilet auger to make sure nothing is stuck in the pipe or trap.

To unclog the drain pipe, remove the machine's drain hose from the pipe or sink drain, being careful to contain any water in it. Next, use a plunger for sink drains or a plumbing snake for a wall drain. Test the repair by pouring a small amount of water into the pipe before trying it with a laundry load.

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups. 

If the drain pump on your washing machine is continuously draining, it could be that the control board is damaged and requires repair, or there’s a clogged or kinked drain hose. If you can’t locate the problem, you’ll want to have a plumber or appliance repair expert come take a look.
