"Jeff, Rob and his crew were exceptional They answered all of my questions even took the time to show me how things worked. They installed a water catch basin and sump pump to replace our smaller 25 year old equipment. Jeff suggested a better pump They were meticulous in their work and cleanup except for the new pump you would not even know they're there. I would recommend ONCE&DONE for any of your waterproofing needs Thank you ONCE&DONE"

"My husband passed away a month ago unexpectedly. Fortunately, he had a Post It note on a wall that said the septic tank needed to be emptied in Sept 2020. So I called Environmental Service Corp. Someone actually answered the phone and got me a soon appointment for the work to be done. When the serviceman came, I had no clue where the septic tank was. He showed me where it was. He also said that the tank only needed to be emptied every 3 years, instead of what another company had told my husband - every year. I thanked him for his honesty and was very pleased with their service. They are honest and hard workers. Would hire them again!!"

"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."

"I signed up to have a modular log home built on an existing foundation. The builder had a number of specifications that needed to be met to get the foundation ready for the new house. I contacted 8 other companies, but no one could help me with my long list of tasks. When I finally got ahold of Highlander Waterproofing, I started by telling them I was a problem child. I listed all the work that needed to be done and Mike told me that nothing on my list sounded sounded scary. I got a couple of visits from Mario, the manager, and Mike, the senior engineer, and one of their senior job bosses. They were all knowledgeable, helpful, positive, and suggested that I use steel supports instead of concrete to save space. Work started in August when Dewey and JT started knocking off the top 2 courses of block. "The Gents" - Dewey (the job boss) Devon, Jimmy, Matt, and Dave - did wonderful work. Because of Murphy's Law, we had to knock some walls down and rebuild them because of bowing, and we ended up adding an internal French Drain. They set rebar, poured tons of concrete, dug footers, put up steel support beams, installed glass block windows, put down sill plates, and rebuilt the front where the garage doors will be. I cannot even begin to say how pleased I am with the work they did. And they were a lot of fun to boot! They let me video them daily, tease them mercilessly, and they had the good grace to laugh when my dog made off with their breakfast jerky. There is still some work to do when the house actually gets here in April - insulating the outside wall, backfilling, putting the sump pumps in, rebuilding the center wall, and digging footers for the porch. I have absolute confidence in Highlander Waterproofing and "The Gents." I would recommend them highly and with no reservations to anyone who needs foundation work. I will add to this post with the final pictures in April."

"The crew was efficient and answered all our questions. The only reason I didn't give them a 5 rating in customer service is because the sales rep didn't communicate clearly enough with the work crew about no large equipment on our drain field."

French Drains FAQs, answered by experts

Start by pouring hot—but not boiling—water down the drain. The heat of the water may be enough to break down the clog. You can also try ½ cup of dish soap or 1 cup each of white vinegar and baking soda. If you choose a chemical unclogging product, ensure it’s appropriate for toilets to avoid damage.

You can often unclog a garbage disposal in less than 10 minutes, though sometimes you might need longer if you’re unsure what’s causing the clog. For minor clogs, consider plunging the drain, flushing the drain with baking soda and vinegar, or using an Allen wrench to free the clog. If the clog is more severe, contact a local plumber.

Unlike regular cleanings, snaking your sewer line should be done as needed. There’s no reason to snake your sewer line if you don’t have any noticeable issues, like slow drainage or plugged drains. You can add it to your regular sewer cleaning checklist as a prevention method (on the same 18- to 22-month schedule), but it’s not always necessary. 

Yes, flushing a clogged toilet can make it overflow. While flushing the toilet may push enough pressure through the system to dislodge the clog, this is unlikely. Your best bet is to use a plunger and hope the suction can break up whatever is blocking the pipe. If this doesn’t work, use a plumbing auger or call a pro to help.

There are a few reasons your snake won’t go down the floor drain. One common reason is a large obstruction in the drain that is causing a blockage. You can remove any debris you see in the drain before trying to snake it. In addition, the snake might not be long enough to reach the clog, or it might be the wrong diameter.
