"Chris G and John did an excellent job! DB’s Plumbing and Drain is an outstanding company. This job may seem a bit expensive but I ordered 2 higher end toilets and they had to deliver, install, and haul away old toilets. I have also hired them in the past to fix my water heater. All the technicians I’ve met are very professional and punctual! I will definitely hire for any future work!"

""After 15 years of enduring water and flooding damage to our yard and the foundation of our house, and after trying various 'solutions' from well-intentioned landscapers that never truly resolved the issues, we ultimately decided to engage Drainage and Erosion Solutions. We required comprehensive flood control and damage mitigation, and their expert team skillfully implemented swales, dry creeks, catch basins, and channel drains in areas where water management was critical. They also replaced a water-damaged window well, removed a flagstone patio to install drain basins and drainage pipes, and flawlessly reinstalled it. The supervisor and crew displayed remarkable knowledge, professionalism, and an unwavering commitment to detail throughout the entire project. This system has been operational for several months now, and even during the most intense rainfall, which historically led to road flooding, my house and foundation remain dry. We enthusiastically endorse this company without reservation.""

"My experience with this company was great. I was able to tell them my issues and they gave me several options. Ultimately we went for the full French Drain system. Everything was done on time and the estimates were very fair. Warranty on the work is great. I would call them again if needed."

"Terence came out today for my slow kitchen drain. We have had problems with it in the past and discussed the previous issues with him. He gave me my options from snaking the current setup to replacement of different sections. We went with replacement of larger segments of our older pipe and Terence included clean outs for easier access if we ever have problems further down the drain in area that we didn’t replace. He came out right away and did a great job. I’m very happy."

"Clifton Contracting does outstanding work. The drainage and water erosion solution installed by Clifton Contracting at our home gives us peace of mind, no matter how heavy the rainfall. After a neighbor on ground higher than us installed yard drains for his gutters that were directed at us, we were inundated with water every rain event. Since Clifton's drainage solution, we have no problems. Their work was efficient, professional and well worth the reasonable cost."

"It was fine. They did the job in two days. We questioned if the length of the drain pipe was enough - we didn't think it was actually long enough to go around the house but they said it would be fine. That's where the problem occurred. They didn't go further around the house. They put in box drains, but now there's flooding that comes around the house from the box drains. I'm having problems with my downspout now too. There's no enough length for it to drain out to the side out the house and it's backing up and flooding at the corner of my house and on the side of my house by the last box drain. I asked them to come out and take a look. They sent out a quality control person to take a look. He told me that it's doing the job that it's supposed to do, but it would need to be extended towards the front of the yard. He gave me a quote of $4,000. We already paid $8,000 for the work. I was shocked. We had asked them 3 times if they thought the length would have been enough. The quality control person talked to his boss and brought the price down to $3000, but that's ridiculous. I went with them because of good reviews on Angie's List, but when there's a problem they won't work with you. If they would have figured it out in the first place- it would have made their estimate a lot higher and I may not have worked with them. I had gotten estimate from other people but choice them. UPDATE: 8/11/2017 The contractor has resolved the issue with the drain system. He was responsive and he resolved the issue quickly to how we wanted it fixed. He responded quickly and it says a lot for his company. He took the reviews seriously and he wanted to make sure that the customer was satisfied and it is very important to him to keep up his good reputation being in Angie's List. This says a lot about their customer service!"

"Overall, very nice job and finished look. Removal of old grout raised significant amounts of dust that got into just about everything near by. Perhaps use of a water slurry or some form of better dust control during grout removal would cut down on the amount of dust/clean-up."

French Drains FAQs, answered by experts

For disposal clogs with standing water, use a sink plunger and place it over the garbage disposal drain. Push the sink plunger up and down the drain about six to eight times before lifting. If the sink drains, the clogged food particles are dislodged from the drain. If there’s still standing water, repeat the steps until the standing water clears out. 

In some cases, operating a snake can damage your drain and pipes. This depends on the overall condition of your pipes and how gently you operate the auger. For instance, older galvanized pipes covered in zinc are susceptible to scratches when using a drain snake. Additionally, it’s common for newbies to apply too much force when extending the snake, leading to scratches and related damage. You can also crack the porcelain with an electric auger if you’re snaking a toilet drain. If you’re using a manual snake or auger, the risk is minimal.

Applying drain cleaner is a common DIY solution to clogged drains, but it can be extremely harmful to your pipes and lead to corrosion and leaks. It is almost always better to try snaking a clog than using a drain cleaner, but the best solution is to hire a professional plumber. They can locate the clog and gauge the severity using a camera system and then decide if using a plumber’s snake, auger, or drain cleaner is the best option to remove the clog and limit damage to your plumbing system.

To unclog a plumbing vent, you first need to locate it. Look at your home's roofline. The plumbing vent will be a vertical pipe sticking straight up from the roof. Since this pipe runs all the way to the main drain underneath your house, you should also be able to find it in the attic.

To prevent drain clogs, perform regular maintenance and cleaning. Avoid disposing of substances like grease or coffee grounds down the sink. Additionally, installing and routinely using drain strainers can help catch debris and prevent blockages from forming.
