"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."

"Aaron was very professional and easy to work with. He clearly described what needed to be done along with the cost for the fix. He was able to fix our problem the same day he contacted us. He was very knowledgeable and provided multiple options for the service. The issue was fixed properly and he had all of the necessary parts on hand. He also guaranteed the work. I would definitely recommend Drip Drop Plumbing and Drains."

"Drytech contacted me about my inquiry for a drain system in my driveway. We set up a date and time. The company called the day before â to confirm the time. The representative arrived on time. We discussed the issues w/ my driveway, and my concerns. After discussions he told me that I probably did not need a drain system. While he did not complete any work for based (because of his honesty) I was impressed with his questions, the time he spent with me and how pleasant he was. He left me his card and informed me what issues to look for."

Foundation Drain Installation FAQs, answered by experts

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.

The type of stormwater drainage system you need depends on your area’s storm severity and frequency. Your property’s location should also be considered, including the surrounding soil type, nearest roads, existing drainage systems, and slopes and hills. Your property’s structure, such as decks, walkways, crawl spaces, and foundation, also affects what drainage system will work the best.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

Gravity can make it difficult to make plumbing work in a garage if your plumbing is lower than your drainage point. Fortunately, there are ways to create drainage when adding a bathroom to a sunken garage. Plumbers will recommend using an upflush system that discharges into a pump from the back of the toilet.

In most cases, standard homeowners insurance policies do not cover damage from a sump pump failure or overflow. Coverage for water damage is often limited to sudden, unexpected events like a burst pipe that was not caused by negligence. To be covered for sump pump issues, you will likely need to purchase a specific rider, endorsement, or additional water backup insurance. If your insurer offers this type of coverage, they may require proof that your sump pump is regularly maintained.
