"Fantastic! Still so happy about how everything went and how professional and knowledgable Sean was and what a pleasure he was to work with. We have been busy transforming a dank, disgusting old fieldstone foundation basement that had a variety of water issues into usable space. Between creating a lapidary work area for our son, an art area for me and some play area for our grandkids, we have been busy and so glad we called Century. Not only did Sean do the job right, well and fairly, he was flexible and ____ when we discovered we had an issue with the lobby columns. We were also very impressed with the people who worked for Century, such hard workers, polite and efficient. I have referred Sean and Century to many people already and would use his services again if the need arises."

"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."

"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"

"We recently had the pleasure of hiring Dawson Mechanical to have a new Navien tankless water heater installed. This was a little more than a straightforward job since the water heater was being relocated from a utility closet to the garage which was about 20 feet away. From the time I made the first call to Dawson, I had a good feeling about this company. Dave came over within a few days on a Saturday to look the job over and give me an estimate. He is very knowledgeable and took the time to answer any questions we had. When the day came for the installation, a crew of 3 workmen arrived around 9:00 AM and did not stop until the job was finished around 5:00 PM. They did an excellent job, were very good about keeping everything clean and neat, and the workmanship was top notch. In short, we were very happy with everything and would not hesitate to use Dawson for our future plumbing/HVAC needs."

"I hired NJ Pro Plumbing for a clogged drain that I just couldn't clear. Brady arrived on time to fix the clog and had the problem solved within minutes. He was friendly and professional and explained where the clog was located in detail. The price was reasonable and I recommend them for anyone searching for a reliable plumber."

"We have worked with Quality First Basement for 20 years. First job was the triple sump pump which has been excellent. Next was the refinishing of our basement. Another superb product and experience. Today we had new flooring installed. Once again, the product and workers were excellent! They were on time and so respectful. The floor is so attractive. This is a company that has only gotten better over the years! I highly recommend it! Rachel Padian"

"John & his crew did an excellent job repairing my foundation & also cleaned & painted using epoxy on my basement walls...no more musty smell! Without me asking, John did other small repairs unrelated to what I hired him for. John & his men did a very neat job in a timely fashion. I would highly recommend him."

Foundation Drain Installation questions, answered by experts

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

DIY is possible for small systems like French drains. Professional installation ensures proper grading and long-term effectiveness.

Heavy rain can affect a leach field because the extra rain can cause the groundwater level to rise. This leads the soil around the leach field to become saturated with rainwater, so it’s no longer able to take in effluent from the leach lines for final treatment. Heavy rainfall can cause the leach field to flood.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.
