"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.

"I was very worried about my foundation since my sidewalks were tilted in toward the foundation after sinking in from their original position. My foundation is styrofoam, and I was afraid we would gouge the foundation since flashing had been glued to the foundation. Roger Webb was here on the date written on his proposal. I was amazed that the work was completed in 3 days. He removed and hauled away my original sidewalks. He installed french drains to re-route rain water going toward my house. New sidewalks were poured. A deck was removed, and reinstalled on the new sidewalks. Finally, gravel was applied next to the new sidewalks, and all extra gravel was applied to the gravel driveway. RW Construction is a reliable and talented group. They were friendly, and glad to accommodate all my special requests. I will use them for other projects in the future, and I highly recommend them for a variety of construction projects as they build complete homes from start to finish."

French Drains FAQs, answered by experts

Professionals use snakes, hydrojetting, or chemical cleaners to clear blockages effectively without damaging pipes.

Using less toilet paper is the easiest way to prevent future clogs. Also, avoid flushing sanitary products, thick paper towels, or hair down the toilet. If you’ve been using a brick in the tank to reduce the water used to flush the toilet, take it out immediately. Bricks will eventually fall apart and clog your toilet drain. Keeping your toilet lid closed also helps avoid future clogs.

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.

Yes, you can pour water down the toilet to help it flush. For each flush, you’ll need 1 to 2 gallons of water for newer toilets or 3 to 5 gallons of water for older toilets. Rather than dumping the entire bucket in all at once, pour the water in slowly for the best results. If you’re pouring water down the toilet to help it flush after a clog, only use 1 gallon of hot water.
