"They were very helpful and professional. Glen responded to all of my questions in depth and worked hard to get my business to waterproof and eliminate mold. There have been a few hard rains since they completed their work, and I haven't had any water in the basement so far."

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

"Bobby and his crew answered all my questions, they were respectful and extremely helpful. Bobby and crew went above and beyond what was on the contract. My house looks beautiful, they power washed entire building, pained the sidewall of the building with thorocoat, front of house was pointed where necessary and applied waterproofing sealer, glass block window, painted stoop and stairs, cemented cracks on stoop and sidewalk, painted outside railing and applied cement in basement where needed. I have to say some of what was done wasnâ  t even on the contract, so they went above what was expected and to my surprise Bobby didnâ  t charge extra. Being a single woman who has had bad experiences with contractors and their disgraceful personalities, having Bobby and his crew work on my property was a pleasure and breath of fresh air. I would hire Bobby and his crew again and recommend them in a heart beat. Best work!!"

"Great! John, the owner was super helpful and nice on the phone. Eased all our concerns. The crew, Phil and Tim, showed up right on time and were able to locate the service caps in the lawn in 10 minutes. They showed me clearly how full the tanks were and clearly explained the problem and the solution. The prices quoted were very fair and there were no surprises. It took around 90 minutes. The job was all done outdoors and when they left you would never know it was done. Very neat and professional. The odors, etc we had were gone and we noticed the drains all flowing more freely. Exactly as they said. So glad we had this done before it became a serious and ugly problem inside the house. We highly recommend Priority Cesspool Sewer and Drain. Thank you!"

"Called about a basement sewer backup and couldn't be happier with the service. This guy is the doctor of draining — diagnosed the issue fast and had everything flowing again in no time. Professional, honest, and clearly knows what he's doing. Highly recommend, don't hesitate to call him if you're dealing with a drain or sewer issue!""

"All their work was excellent. Not only did they replace our roof and repair water damage in our dining room, we had them do other jobs too. Replacement basement windows, outdoor lighting, and fencing. I would definitely hire them again."

"Im am so happy with the work that was done on my house. Tyler came and gave a very fair estimate on lifting my concrete side entrance stairs to my basement. He explained every step of the process and did exactly what we wanted with no issues. Everything was done to perfection. No damage was done and you cant even tell the stairs ever needed a repair in the first place. I would highly recommend this company and would hire again for any future jobs."

Basement Waterproofing FAQs, answered by experts

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

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.

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.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

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.
