"French drains were put in my yard from one end to the other and around the side -- a big area that was holding water and ruining my lawn. Dani was very knowledgeable and accessible. He and his crew were professional and courteous. The crew cleaned up everything as they went along. It looks great but more importantly, it works great. I highly recommend them for yard drainage problems."

"The job went great! They were able to remove a very large drainpipe that was 5 feet below the road. Additionally they installed a larger pipe for us, and did an excellent job getting it seated in place and covering it up. The road going into our farm doesn't flood anymore and the water is able to drain nicely on the sides where they helped dig the angle much better than any piece of farm equipment we had on hand. Mr. Lozy was kind enough to help us dig a really small pond for the deer as well. With his excavator it took 3 minutes, what would have taken me 18 hours and a broken back to do with a shovel."

"Having owned four different houses the past 16 years, this was hands down the best experience with a plumber... ever. We hired WyattWorks to install a laundry sink (the stainless over cabinet kind) which required drilling through the floor to tie-in with supply and drain pipes in our basement. Jeremy performed the work flawlessly and was a true pro: measure and recheck, plan and dry fit, and clean up the work area during and after. The whole process from start to finish was painless!"

"Scrubbed mold from wooden support members under concrete porch. More than willing to retouch areas that I felt needed fine tuning. Allowed to dry & double coated with antimicrobial sealer. Hand dug in different area down to French Drain in attempt to cap off & re-route. Owner of Falcone drilled several weep holes in concrete blocks that were allowing slight seepage into crawl. Water tested area of concrete patio & bricks that I had installed recently above seepage area in series to correct. Even though he brought his trenching equip for substantial dig that was quoted, Fred felt that I had solved the seepage problem & did not need the modification to french drain. Saved me a bunch of money by not doing this & by not fabricating additional expenses related to trailering equip to the site. Note: Most contractors would have proceeded with the dig needed or not, out of greed. I felt that Fred was very knowledgeable, competent, honest and that he &  his crew were quite focused on making sure that I was a satisfied customer. I would highly recommend his services to friends &/or family. Pleasure doing business with Falcone Crawl Space & Repair

"Brian returned my phone call within an hour and was able to do my repairs the same morning! I am aware this might not always be the case, but I had been trying for 2 weeks to get a plumber to take or return my calls or show an interest in doing my repairs! Brian was extremely polite and professional... he will be getting all my plumbing business from here on out!"

French Drains FAQs, answered by experts

If you've discovered a rather frightening buildup of brown and black gunk below your shower cover, you're not alone. The smelly sludge is often a collection of mildew and biofilm. Biofilm comes from the breakdown of soap scum, hair, skin cells, and bacteria that collects during shower time. It's quite common in a humid space and relatively easy to clean with a gentle DIY cleaning solution such as baking soda and vinegar.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

To clean gunk out of a sink drain, pour in a half cup of baking soda, then 1 cup of white vinegar. The two will react chemically; let them fizz for 15 minutes, then rinse with boiling water. Repeat these steps if necessary for particularly dirty sink drains, and consider a drain snake if there are clogs.

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.
