Customers say: Terrific value

"Mr. Brady was great to work with. I couldnâ t really explain over the phone what needed to be done. He offered to come to the house and talk to us. It was so easy because he knew exactly what the problem was. We didnâ t need a new window, but a new window well! Thatâ s what you get when you hire an expert! He also waterproofed the walls around the basement greenhouse. He and his crew did a great job and I would work with them again if we needed more work to be done."

"We wanted to finish our basement but was hesitant bc of our flooding problems. Home healthy homes solved that for us. They came in waterproofed and removed all mold. We have had heavy rainstorms since and no more floods! Glen and the team are so professional and could not be more helpful. They are reasonable and worth every dime! Highly highly recommend!! They go above and beyond."

"James, his brother Mike and their crew were all you would be looking for in a company. Very polite and respectful. They did all the work as per contract in the time specified. Their workmanship and attention to detail was exceptional. We had other estimates for the same scope of work which came in much higher. We would definitely recommend them for anyone considering basement waterproofing."

"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."

"Had a backup a few days before and wanted to determine if it was a simple clog or cesspool related. They sent out a tech (Jimmy) the same day. He located both cesspools and walked me through my options. He was honest and patient, answering all my questions along the way."

"Lorenzo and his team did an excellent job of building a replacement concrete footing wall to support our stairs going down to the water. They did an excellent job under tough conditions. They were both on time and very neat."

"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

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there’s a lower chance of dust mites breeding and causing allergic reactions in your home.
