They go above and beyond."

"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."

"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!"

"Good job but a little bit pricey. Also, I have my water tank replace and he did dispose of the old tank. Not even, bringing it out of the basement for me to put into street curbside for recycling pickup. I have to hire somebody to bring it up from the basement."

"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."

Basement Waterproofing questions, answered by experts

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they’re tightly laid on top of each other, creating the effect of a firm wall against accumulating water.

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.

The purpose of soffits is to circulate air, so a blocked soffit means the air in your attic becomes stagnant. This can lead to a number of problems, mostly moisture-related, that can cause damage to your health and your home. The good news is that unclogging soffits is relatively straightforward, and if your attic is easy to access, an easy DIY project.
