"We hired Century Masonry & Waterproofing several years ago after suffering through several flooded basements. At a time when some contractors are out there trying to sell unnecessary services and products, Sean is an honest, consultative, helpful professional. He was able to identify problems with our existing sump pit and corrected them. He also identified the fact that the sump pit was not in the lowest point of our foundation and installed a second sump pit and pump there. Thankfully, and knock on wood, we haven't had an issue in years. Thank you Sean and Century Masonry & Waterproofing!"

"Arid did an amazing job! The sales rep, Mike who came out to give us an estimate was very knowledgeable and explained how the whole process worked. He was very patient answering my three pages of questions! The work they did and the equipment they installed was exactly as promised. I stressed out for so many years about getting French drains because I heard it was so messy and you get dust throughout the whole house. I followed their printed recommendations and there was virtually no dust in the floors above the basement. The Foreman, also named Mike, brought a crew of seven men and ran the job like clockwork. The job was completed in just 5 1/2 hours. They cleaned up every piece of debris and even washed down my driveway! Mike explained how the system works and left me all the manuals. I went with their backup pump and battery system, which they designed, for extra peace of mind. I would recommend Arid to anyone thinking about getting French drains. Thank you Arid!"

"As I did the first time I used Bob Lindsay's company, I waited six months to write my review. After withstanding nearly 13" of water from Henri and Ida, I cannot recommend this company enough. We used Bob at my first house and decided to use him again when our final walkthrough of our house revealed a wet carpet in the finished basement. Bob's guys replaced the shallow existing window wells with much deeper, galvanized ones, backfilled them with stone and piped them into a perimeter channel drain that was then flashed and cemented to the basement floor height. The sump pump pit was installed and a battery backup system was provided and wired in. The outside grading around the window wells was also redone to slope any surface water away from the foundation. Due to our Radon mitigation system, a polyurethane caulk was also used to seal the system. We remained absolutely bone-dry these last few weeks despite rain falling at 2-3" per hour in some cases. The work is efficient, his guys are extremely friendly and skilled, and despite the messiness of the job, they do a fabulous job cleaning up. There is a certain peace of mind that having this type of work done provides, and you cannot put a price tag on it, especially if you plan on finishing (or refinishing) a basement. At the end of the job, Bob was even kind enough to have one of his guys tie in a 2" piece of PVC from the floor with a cap (which I then drilled a hole in) so I can run my dehumidifier constantly without ever having to empty the bucket. We have since refinished our basement to our liking and know for certain that this was the best home investment we could have possibly made. A friend of ours has also done her entire basement with Weather-Tite and had an equally wonderful experience. Thanks Bob for saving us not once, but twice."

"I am beyond impressed with Blue Umbrella, the company that installed a French drain in my crawl space. They were professional from start to finish, yet charged thousands less than many other companies. They installed top quality products and completed the job in just one day. Each member of the uniformed team was polite, hard-working, and completely respectful of my home. They used plastic sheeting to enclose the job area and then worked together flawlessly and efficiently for the rest of the day. Blue Umbrella is astonishingly good at what they do, and I am so very glad I found this gem of a company for my installation. Blue Umbrella beats the competition by a mile - I highly recommend them!!!"

"They explained their system and the installation process in detail. They were very flexible and worked with our schedule to finish installation of French drain system before sale of house. Extra foundation work was needed, and they did that as fast as possible"

"Roland contacted us promptly and set up an appointment to evaluate within a few days. We described the water problem we were having and he looked into possible causes. After ruling out a couple of things he said that French drains were the way to go. He accommodated our schedule when setting up a date for the work to begin. Work was started on schedule and was completed over three days. The work crew was pleasant and communicative. On some days the number of people working was pretty large. The project consisted of digging a perimeter trench along the basement wall; installing filler fabric, stone, and perforated PVC pipe to exit into a sump pump; installing a sump pump and a battery backup; connecting the sump pump drainage to our municipal storm drain; drilling out the bottom foundation blocks and mounting drain board to the foundation; re-cementing the concrete floor; reconstructing a concrete platform at the foot of our basement stairs that needed to be removed for the trench to be dug; clean up and removal of debris. All of these things were done expertly. The construction area was curtained off to keep dust and debris isolated. In order to run the drain out to the municipal storm drain it was necessary to dig under a section of sidewalk. The workmen targeted a section of sidewalk that was in need of repair already, so we got the benefit of a repaired sidewalk as well! We knew at the outset that this company does not do electrical work. A power line for the pumps had to be installed by another contractor after the drain was completed."

Foundation Drain Installation FAQs, answered by experts

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

Your sump pump will discharge water through a discharge line or pipe. The discharge line should be placed at least 10–20 feet from the foundation to avoid any issues.

A sump pump battery backup can typically run for 6 to 24 hours. The factors that affect its runtime include the battery capacity and pump usage. 

When purchasing your backup system, take these factors into consideration to determine which system is best for your home. If you live in an area with frequent and long-lasting power outages, consider a longer-lasting backup battery.
