"Excellent all around experience!!!!!!!! After a series of storms and gradual water soaking our basement carpet several times, I finally called Waterproofing One in April, 2017 after seeing their ad several times on our St. Basil's church bulletin. I spoke initially with the owner-Joe who was helpful and he dispatched Dave Cook who came over within an hour. Dave Cook has been in this business and related utility engineering previously for over 30 years and really knows his stuff. Dave was extremely thorough, spending time in the basement, looking at some pictures I took of the damage and spent a considerable amount of time walking around the exterior of my property and reviewing the landscaping where most problems start. Dave wrote up a report of what work was needed including extending downspouts, recommending we have our contractor add a louvered door at the top of the steps for aeration (a great idea given no windows in basement) , waterproofing the well water closet walls, spraying impacted area for potential mold, and installing a new French drain and sump-pump system with battery backup. Gene and his crew then came over on May 17, 2018 and performed the construction and installation work and did a great job. Those guys worked extremely hard in what is inherently a muddy line of work and were very courteous, professional and left the basement very clean. Gene took extra time to show us exactly what they were doing as they drilled holes into the lower cinder block walls, laying of the perforated pipe and some of the damp mold on the wooded studs he extracted at the impacted area. We paid exactly what Dave originally quoted! Dave Cook came back checked on things and made some other recommendations including adding stones around the foundation outside and in holes to avoid soil erosion and soften the acceleration of rain water into the ground. Once the work was finished and our carpenter redid the walls and painting, We had subsequently refinished the basement with high end vapor/mold resistant padding from Mohawk and a quality polyester carpet. 15 months later and here we are on September 30, 2019 after 50+ rain storms since installation and NO WATER nor Mold issues in the basement!!! We are really enjoying our basement again thanks to WATERPROOFING ONE!!!! 5-STARS!!!!!!!!"

"The job was to put a sump pump and French drain into a crawl space off my basement. It was completed in a timely fashion. They removed all material in the crawl space and also sprayed an anti mold solution. When I called company to ask questions Jason kindly explained the answer."

"Really professional and friendly, were able to complet the work way faster than I expected and showed up on time, and finished a day early. I'm very happy and as they were able to fix structural issues as well as put in a french drain at the same time, they took a lot of heartache out of the organisation. The crew were skilled and experienced and happy to share project knowledge. I'm recommending them to my neighbour."

French Drains FAQs, answered by experts

As a preventative measure, hydro jetting should be done every one to two years. However, the best practice is to hydro jet your sewer line once per year. The ideal frequency depends on several factors, including the age and condition of your pipes, how prone they are to clogging, how often the sewer line is used, and the type of waste disposed of in the system. If you frequently experience clogs or are unsure, it's best to ask a licensed plumber for a recommendation specific to your plumbing system.

Air gaps get clogged by a few different means. Over time, food and grime can collect in the air gap, leading to a blockage. Mineral deposits from hard water are a common problem. Mineral buildup creates a film in the air gap and tubing, which can cause flow issues, as well as attract debris. Homeowners with hard water may want to remove mineral deposits regularly to keep the air gap clean and clear.

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.

Liquid drain cleaners are harsh chemicals that can erode your pipes. To treat a slow drain or for preventative maintenance, pour hot water down the drain to break up gunk and help move it along. Make sure the water isn’t boiling hot (keep it under 140 degrees Fahrenheit) if you have plastic pipes. However, you’ll need to pull the clog out for bigger backups. 

Even if the shower drain doesn’t seem clogged or dirty, plan to clean it out about once per month—or more frequently if you or your family shed a lot of hair. It’s a good practice to remove any hair from the drain on a daily basis, as hair can accumulate fast and cause clogs in no time. You may also want to have a plumber thoroughly clean the drains in your home once every six months.
