Existing Crawl space under my home has a possible sealed entrance. Want advice and also want spray foam insulation in crawl space

Water coming from basement walls

Project Location: Massapequa Park, NY

I bought my home 9/2016. I have a front/black split. My crawl space was a mess. I personally cleaned it up (owners left belongings that I did not see during walk through). Last winter it was very cold. I do believe the crawl needs to be insulated. Need help!

Project Location: Massapequa Park, NY

Mold issue in basement. Would like to rectify the root of the problem, not just use a dehumidifier. Goal is to make it another functional living/gathering space once corrected.

We recently found a vertical crack in the concrete foundation. We purchased this house in August and this crack was not there.

Dear Danny, Elizabeth, Brenda, Juan, Carlos, and everyone at Complete Basement Systems,

We do not know how to thank you for your consideration and help during a very trying time on Long Island. Hurricane Irene could have been a tragedy for us and our home, but because of your competence, we had a job well done and it saved us not only great heartache, but great expense. We will definitely recommend your company very highly, not only because of your competence and courteous manner, but also because of your humanity towards Long Islanders.

Thank you and may God bless you always!

Sincerely, Carol and John

Basement Waterproofing in Massapequa Park

We make sure you never have to fear from floods, groundwater seepage, or heavy rain again by properly installing our life-time warranted basement waterproofing system. We install a nearly invisible drainage system and sump pump that includes backup and battery-powered pumps.

Crawl Space Repair

Neglected crawl spaces can lead to moisture problems that result in mold damage, musty odors, rot, and poor insulation making your floors cold, diminishing your home’s value, and risking your health. Our crawl space encapsulation system completely seals the crawl space preventing these problems and comes with a 25 year warranty.

Expert Spray Foam Insulation

Improper insulation, especially in cracks and holes can diminish the comfort of your home and increases your monthly utility cost. Our highly trained technicians will install closed-cell polyurethane spray foam sealing these gaps preventing air flow and heat loss.
