They are extremely responsive, and will always follow through to ensure the customer is being taken care of. Calls, questions, estimates - all of this is done on time, as promised. Paul, who did the consultation, was extremely knowledgeable and did not try to upsell anything. The crew that came out were professional, and maintained a clean working area. Dust control was excellent. Their prices are very reasonable, and they will not nickel and dime. They will work with you throughout the project. Quality work, honest people. So far the system they put in place has been working as advertised. Would highly recommend this company."

"I dealt with the owner Paul from start to finish. We had purchased all of the materials for the renovation of our bathroom as well as our master bedroom, halls and entire first floor ceiling. Paul and his crew made our entire plan come alive and completed the project in the time span they had promised. We are thrilled with how well every thing went. We had them do an additional project on the exterior of our house after completion of the interior work and this was handled as well. the few minor problems that occurred were rectified with no delay, and to our complete satisfaction."

Patzan Home Improvement is your go to team for all of your home needs. We work tirelessly to meet and exceed your expectations and constantly strive for perfection. Give us a call today and lets get started!

"I can't say enough about these people! They exceeded every expectation. We hired them to replace our kitchen cabinets and replace the lights in four rooms and paint those rooms, as well as wallpaper a bathroom and install a lighted mirror in it. They worked hard, every day, full days, until the job was complete. They did it in under three weeks! And every detail is perfect. Geovanni offered to address features we hadn't thought of. And they charged a fraction of the amount of money that another contractor quoted us. The crew was professional and pleasant. We felt comfortable having them in our home even on days when we were not in the house. You can't do better than to hire Patzan."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Ronkonkoma, NY

Standing water in your crawl space won’t disappear on its own. Keep the drainage clear, ensure the vents are working properly, and run a dehumidifier to control moisture levels. If dampness lingers, mold, wood rot, and foundation cracks can follow. Act quickly and call a pro to protect your home’s structure and indoor air quality.

Disinfecting a crawl space requires a methodical approach. First, clear all debris and remove old liners and insulation to eliminate contaminants. Then, apply a strong bleach solution or borate spray to eradicate mold spores and mildew. Ensuring complete surface coverage and allowing ample drying time establishes a sanitary environment and prevents future infestations.

A crawl space serves vital functions by providing access to essential systems, including electrical wiring, plumbing, and HVAC ducts. It also offers a buffer zone that aids in moisture control and protects underlying structural components. 

Yes, crawl space encapsulation is a worthwhile investment in protecting your home. Crawl space encapsulation locks out moisture, controls humidity, and blocks pests and harmful pollutants like radon gas. Those benefits boost indoor air quality and protect beams, joists, and insulation, giving your home long‑term structural stability and safeguarding your family’s health.

Prevention is the best way to keep water out of your crawl space. A dehumidifier and sump pump can help control moisture levels, but grading the landscape to redirect water away from the foundation is most important. Additionally, seal foundation cracks and install reliable drainage systems such as a French drain to maintain a consistently dry environment.

Yes, repairing your crawl space foundation is critical, regardless of how minor the issue may seem. Foundation problems arise from enduring moisture, water intrusion, and unstable soil, which can lead to significant structural damage if left unaddressed. Hiring a licensed structural engineer or foundation repair professional guarantees your home’s long-term stability and safety while preventing escalating repair costs.
