"It is very hard to find someone who is not only willing to work hard, but get the job done right the first time. Masle and his crew were out working in the rain getting my drains project in on time and under budget! Simply amazing. I am overjoyed at the quality of work, the communication, and the attention to detail. These folks are all you need I assure you."

"I have a walkout basement that has trouble in severe rains that floods my basement under the door. We had a small sump pump installed, but it did not help Memorial weekend when we had Biblical rains hit the area. My sump and shopvac were working overtime as the ground was so saturated. I called four contractors for estimates. Falcone was the first to show up three days later. Chris spent a great deal of time talking with us on our concerns and inspecting our property. He gave us a fast and fair quote. Our job was able to be completed within three weeks of scheduling it. It took four days for Chris, Kenny and their crew to install an internal french drain system in my basement and crawl space as well as a door drain along with a sump and backup. They were kind, respectful, and efficient. They did a great job and cleaned up the basement work area and my property when they were done. Maryl in the business office was great to work with. Everyone I was in contact with at Falcone was communicative and very nice to deal with. I would definitely recommend and would call on them again in a heartbeat. Thanks!"

"The representative who initially came to the house to explain BDry's procedure was very courteous and professional. I received a quote on the spot. I had two other companies come out (one company did not even bother to get back to me with an estimate). Each company had a different opinion of what needed to be done and BDry's procedure was the least invasive and made the most sense. The team who actually did the work was very courteous and stayed until the job was done - a 12 hour process. (That was one question I didn't think to ask - approximately how long would it take) They communicated with us throughout the day, for example they asked where we wanted the sump pump to drain, instead of just making the decision. Overall, I am very happy we chose BDry.!"

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.

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.

Yes, frozen pipes can cause a toilet to stop working correctly. If the pipes are frozen, water cannot flow, which can lead to two main problems. First, the supply line to the toilet tank may be frozen, which prevents the tank from refilling with water after you flush. Second, the drain pipe itself can freeze, blocking water from flushing away. As a temporary solution for a non-refilling tank, you can manually add water, but this is not a long-term fix. To clear a frozen drain pipe, you can try pouring warm water into the toilet bowl or tank and then flushing, as the warm water may help thaw the ice blockage. Ultimately, the best course of action is to unfreeze the affected pipes to restore your toilet to full functionality.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

There are a couple of things you can do to help prevent your French drain grate from clogging. First, keep yard debris clear so it doesn’t wash into the drain and clog the grate. You can also install a screen or filter over the grate to prevent large pieces of debris from entering the access point.
