"Outstanding service and value. Prostar Waterproofing and Construction were one of the most responsive and professional businesses I've come across. From start to finish, a pleasure to work with. 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."

"The rooftop of our apartment building had leaks that lasted several years and patchwork repairs from different contractors never resolved the ongoing leak issue. The building board interviewed several contractors, all of whom wanted to entirely replace the roof for a very high price. Atif (owner) was able to isolate the problem area of the roof without replacing the entire roof at a much lower price point with a guarantee. The work was done quickly and efficiently. I highly recommend Atif and his team for their professionalism, dedication and most of all honesty. It’s been 3 years (with severe storms) and we haven’t had a leak since 😃. "

Z Abedin Construction is backed with 32 years of experience! We specialize in high quality workmanship with fair pricing for all Brownstone Restoration and concrete projects. No job is too small or too big! We offer the highest-quality work with the most professional people. Our craftsmanship results in pride for our clients’, meeting their individual needs. At Z Abedin Construction, we pride ourselves on integrity, cleanliness, professional courtesy, timeliness, reliability and having a strong reputation among our clients! Thank you for considering Z Abedin Construction and we look forward to impressing you!

"What we expected to be an 8-week project ballooned into a 16-week project, delayed largely by rainy weather and perhaps some mis-scheduling on the company's end as it juggles multiple projects. Be aware that your project's projected timeframe may very likely be extended; Abedin is in high demand. This was the most frustrating part of the process, having the project at a standstill with a large 3-storey scaffolding out front blocking sunlight and bags of cements and other work items in the courtyard. However, whenever I did call Abedin to find out the status and when work would resume, he was readily accessible and responsive. The craftsmanship is exemplary and it's apparent that the workers are highly skilled and take great pride in their work. I also greatly appreciated that the workers cleaned the site daily after working. This is HUGELY important because the worksite is also my home and not an uninhabited construction site. This meant a great deal to me and Abedin was often on site or sent a supervisor on site to assist and inspect. Abedin is hands-on and has high standards, which keeps the works not only focused and accountable, but motivated. Here's an important tip: where possible, throughout the process, protect your historic fence and railings with a drop cloth because they, like the courtyard's surface, will be battered. Abedin promised to repaint after the work was completed and his guys did, but the repainting job did not match the quality of restoration work we had previously paid for with the ironwork restoration contractor. Despite the setbacks and extended project time, my husband and I are extremely happy with our restoration project and the craftsmanship. Our brownstone looks completely transformed and historic and beautiful! Should we have future brownstone restoration needs, Abedin will definitely be our choice. Thank you."

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

Cleaning your crawl space is a worthwhile investment for several important reasons. A properly maintained crawl space prevents structural damage by eliminating moisture that can deteriorate wood supports and metal components. It also significantly improves your home's indoor air quality by removing allergens like mold spores and pest droppings that can circulate through your living spaces. 

Additionally, a clean crawl space contributes to better energy efficiency by allowing proper insulation installation and reducing humidity levels that force your HVAC system to work harder.

Several warning signs indicate your crawl space needs professional attention. Look for musty odors throughout your home, unexplained increases in allergy symptoms, higher energy bills, visible pest activity, or moisture issues. 

Other indicators include sagging floors, warped wood, visible mold growth, standing water, or damaged insulation. If your crawl space hasn't been inspected in over a year, or if you've recently experienced flooding or severe weather, it's advisable to have professionals assess the space even without obvious symptoms.

Most crawl space cleaning projects take between one and three days to complete, depending on several factors. Simple debris removal in a small, relatively clean space might be finished in a single day. 

More involved projects that include mold remediation, water damage repair, or pest control require two to three days. For large crawl spaces or those with extensive contamination, the timeline might extend to a week, particularly if additional services like encapsulation are included in the project scope.

You can remain in your home during basic crawl space cleaning. However, if the project involves mold remediation or pest extermination with chemical treatments, temporary relocation might be recommended, especially for household members with respiratory conditions or chemical sensitivities. 

Professional cleaning companies use containment procedures to minimize the spread of dust and contaminants into living spaces, but some disruption is inevitable. Discuss your specific situation with your service provider to determine the best approach for your family's needs.
