"I highly recommend National Pro Waterproofing for all of your basement waterproofing needs. I had a complex job that included over 200 feet of an internal french drain system, several sump pumps, several window drains, several foundation wall repairs, a couple of floor drains, and a discharge line with a pop up drain emitter that was dug as a trench by existing landscaping outside to move water away from the foundation. Such a job can be overwhelming especially with active moisture infiltration, but National Pro Waterproofing made it seamless from start to finish and completed the job in just 2 days, which was very impressive. From the extremely responsive communication to the attention to detail of their craft, I could not be happier with their service and how it was all coordinated. The entire team arrived on time, cleaned all areas, and provided guidance on how to maintain a functional system for years to come. I now have peace of mind that my basement is safe from any moisture."

"The previous owner of our property used his French drain installation as a selling point, but shortly after we moved in we found water in the basement after a storm. It turned out that the "French drains" were a trench at the edges of the basement and a sump pump. The drains were not piped to the sump pump. We had Arid install real French drains with pipe to the sump pump well. Thus was in 2005 and we have not had any water in the basement since. Pat explained the job well and his team performed it quickly. They cleaned up well afterwards. The pump finally gave out last night (after almost 12 years). Arid is going to install new one on Friday."

"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."

"Had a Sump Pump and French Drain installed, Mold Removal and a major repair to a foundation wall. Absolute Waterproofing and Renovations were highly recommended to me by a gentleman that does business with them everyday. Lou and his guys came when he said they would, finished when they said they would. They protected my house from dust and dirt by covering everything with plastic. The price was the most reasonable in comparison. They were professional, clean and trustworthy. They actually found a gold wedding band that was missing for months and were honest enough to return it to us. I'm 100% satisfied with the the work that was done and 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"

"I can't say enough good things about American A-1 Waterproofing. Roland and his team were amazing. I had originally opted to go with another contractor to install a French drain and sump pump, but after exposing the foundation, they got spooked and said they wouldn't perform the work. Roland came by and assured me his team could get the work done and they did not disappoint. Through the initial estimate, permitting, construction and final sign off, Roland and his team were communicative, prompt, clean, and extremely professional. It was an absolute pleasure to work with them!"

"They encountered a problem that did not respond to the standard treatment, so they had to work longer, "figure it out", and bring in other equipment. They did, and they refused to charge me any more than their standard price for drain clearing. Outstanding service."

"From initial call to final installation was impressed all around with professionalism with this company. I have never had work performed in my home that went as smoothly as this did. And when the installers left it was like they were never here... they left it as clean as it was when they got here."

Foundation Drain Installation FAQs, answered by experts

A range of certified professionals can install French drains, from foundation specialists to plumbers. However, you’ll want to make sure that the professional has a breadth of experience installing the specific type of drain you need in or outside your home. Your contractor should also have experience with sump pumps, waterproofing, and flood-proof landscaping.

There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it. 

Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.

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 move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

Yes, professionals ensure proper grading and drainage to prevent water pooling.

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.
