"I walked into my basement on Saturday afternoon to discover a pool of water on the floor.  Looking at the walls I traced it back to right above the window that sits below my kitchen sink.  I popped the paneling off the top of the window box and immediately saw that the galvanized pipe leading from the sink drain to the stack had corroded and a hole had formed.  Frantic because it was 4pm on a Saturday and I knew I couldn't use my kitchen sink or dishwasher until I got this fixed (no easy task with two toddlers to keep up with), I jumped onto Angie's List looking for a plumber with Saturday hours and a good rating. 
I called McDonagh and was told they could have someone at my place in an hour.  Todd showed up at 5:30 and immediately got to work.  Patrick (the owner) showed up with his son Nolan shortly thereafter to take a look and get Todd some parts off of his truck.  We gave Nolan a piece of the pizza my kids were having for dinner as an apology for interrupting his Saturday too.  Patrick came back with a price estimate that seemed fair to me for emergency short-notice service on a Saturday night.  Todd replaced the entire section of pipe from the sink drain to the stack and was finished and out the door by 7:30, leaving us with a fully functional kitchen again. 
Huge thanks to Patrick and Todd (and Nolan) who really saved the day for us.  These guys are absolute professionals and really saved us from some major inconvenience.  Would absolutely recommend and use them again.

"This review is well over due. Now that we have the drain tile system we have not received any flooding The day he began Brian's team came to our house promptly in the morning at 8am. They immediately started jack hammering the floor around the perimeter of the basement. While two men jack hammered on opposite ends the rest of the team followed behind them clearing debris and bringing the large pieces to a truck to be hauled away. They then installed the drain pipe, sump pumps, and poured cement. They were able to compete the project within 8 hours. I was definitely impressed! Now that it is a year later with 3 seasons behind us we cannot complain about his installation of the drainage system. Furthermore, one year later he still provided us with exceptional customer service. Oddly enough our pipes connected to our sump pump that takes the water from the drain tile to the backyard became detached. He responded asap with putting the detached pipes from the sump pump back together and making sure what happened will not happen again. What I liked about him in comparison to the other companies was his approach. No sales techniques, nothing gimmicky just genuine and straight shooter type of guy. He believes in his service, no thrills and whistles to the product. Just common sense solutions with quality service. It's your house your investment. Call this guy, no "BS" to it. He won't let you down.

"Rardins has merged with Mattex Plumbing, but Oscar Rardin is still with them. Very professional, both over the phone and kept me updated through texts on the phone. Showed up as promised and was done within 3 hours. Only real difference was in how prices have inflated since 2014 (last time pump was replaced) $1400 vs $500 The pump accounted for over $1200 of that total. Oscar did a excellent job!"

"I was very pleased with the service Agape provided.  I used the special deal provided by Angie's List and Agape.  I informed Agape the leaves were down.  I could not even tell they had been here....there were no leaves left on the sidewalks or any other signs.  I could see the limb had been pruned and water at the end of my long drain.  Communication was fine and people were pleasant.  I will definitely ask them to come back in spring when the seedlings grow in the gutters. Way to go, Agape.

French Drains FAQs, answered by experts

To keep your toilet from clogging, you can use less toilet paper. You can also use a liquid toilet plunger to break up any clogs and keep the toilet drain and pipes clear. When it comes to a clogged toilet, the best route is prevention by using less toilet paper and making sure the mechanisms are all working properly.

If you don’t have a sewer cleanout, clearing out clogs can be extremely difficult. You would need to try to clear the clog from sink drains, but it can be harder to reach the clog all the way in the drain line. A sewer cleanout makes it much faster and easier for pros to clear clogs from your main sewer line.

A liquid drain cleaner can sometimes make a clog worse over time if you use it improperly or too much. The chemicals in drain cleaners can corrode and damage pipes, causing cracks and leaks that may cause further blockages. If the clog is more than the liquid drain cleaner can handle, the cleaner will simply add chemicals to a bigger overall problem.

Yes, you can use vinegar to unclog a dishwasher. To do so, combine 4 tablespoons of white vinegar with 4 tablespoons of baking soda and pour the mixture down your dishwasher’s drain. Let it sit for 15 minutes, then pour a cup of hot water down the drain to flush everything out. Finally, run a rinse cycle on your dishwasher to see if the clog is gone.

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.
