What this listing says
Long Island and NYC property owners dealing with water damage, fire, or mold who want one general contractor to handle remediation and full reconstruction under a single insurance claim.
Best for
- Long Island homeowners who need water damage, mold, or fire restoration handled from emergency response through full reconstruction without coordinating multiple contractors.
- Property owners with insurance claims who want the contractor to document the loss and communicate directly with the adjuster from day one.
- Pre-1980 building owners in Nassau, Suffolk, or NYC who need mold remediation and asbestos abatement handled by the same contractor before a renovation.
- Commercial property managers and landlords across Long Island and the five boroughs who need 24/7 emergency response with NYC DOB permit capability.
About this company
Madison Ave Construction is a general contractor based in Deer Park, Long Island, that built its business around emergency restoration and expanded into a full-service operation covering water damage, fire and smoke cleanup, mold remediation, roofing, plumbing, asbestos abatement, demolition, and commercial construction. They hold IICRC certifications in water restoration (WRT), mold remediation (AMRT), and fire restoration (FSRT), and they handle the entire scope from emergency mitigation through reconstruction under one contract. The owner, Bob Chiarello, is the primary point of contact and runs the insurance coordination side personally.
What stands out is the single-contractor model. Most restoration companies hand off the rebuild to a separate general contractor, which creates gaps in accountability between the mitigation team and the construction crew. Madison Ave keeps both phases in-house. Their website describes psychrometric monitoring during drying, negative air pressure containment for mold work, HEPA air scrubbing, and post-remediation clearance testing through independent labs. They also hold a NYS DOL asbestos contractor license, which is unusual for a restoration company and means they can handle pre-renovation asbestos surveys and abatement without bringing in a third party.
They claim 25+ years in business, operating since 1999 from the same Deer Park location. The email on their website goes directly to Bob. Multiple reviews reference him answering calls personally, including late-night emergencies. The operation reads as owner-operated with field crews rather than a franchise model.
A 5.0 rating across 110 Google reviews is statistically unusual. It places them at the ceiling of what Google's review system produces at any meaningful volume. The negative reviews that do exist are minimal in number and detail.
Services
Service area
Based in Deer Park, Suffolk County. Serves all of Nassau and Suffolk County on Long Island, all five NYC boroughs (Manhattan, Brooklyn, Queens, the Bronx, Staten Island), and Westchester County. Claims 60-minute emergency response across Long Island and NYC, though properties at the edges of this coverage area should confirm response times.
Review consensus
Bob (the owner) is named repeatedly for fast personal response to emergency calls, calm explanations of the process, and hands-on insurance claim management. Multiple reviewers say he answered the phone late at night and had crews on-site within the hour. Bobby is praised by Yana Iskhakova and David Taylor for direct involvement. Ray is named by Felix Adamkiewicz for a kitchen rebuild, described as meticulous with craftsmanship and detail. Hector is named by Richard Morello as part of an excellent flood rebuild crew. Bill (Billy) is named by Jeffry Petracca for managing a sewage backup restoration and by Edward Gomez for water damage work. Reviewers consistently highlight insurance coordination as a major strength, with several noting that Madison Ave got them significantly more from their carrier than the initial adjuster offer. Repeat customers include a property manager (Thomas P.) who has used them twice and a family (Chenne Bailey-Cox) who used them on two properties.
2 found across 110 total reviews at 5.0★. James Connor left a 1-star review in November 2025 calling it the "worst experience" and saying he regrets using them, but provided no specifics about what went wrong. A second negative, a 2-star review from a zero-review account, contains no text at all. Neither review received an owner response.
The review profile has notable clustering patterns. Seven reviews from single-review accounts appeared on July 28, 2025. Five reviews appeared on a single day, February 22, 2026, including two from Kenny De Bruycker (same name, both single-review accounts). A block of reviews from late March 2026 comes from accounts with names suggesting a shared demographic (Md Mahadi, Md Emon Khan, Md Robin, md mamun) and all are single-review accounts with generic restoration narratives. These patterns do not confirm inauthenticity, but the clustering is worth noting. The established reviewers (Local Guides with review histories, like Erica Boni at 54 reviews, Shakira Alston at 178, Philip Bailey at 50, and Jessica C at 18) are uniformly positive and provide detailed, specific accounts. The 0% owner response rate on negatives is also notable for a company actively managing its online presence.
Bob / Bobby (owner — praised repeatedly for emergency response, insurance coordination, and personal accessibility). Ray (rebuild crew — praised for craftsmanship on kitchen rebuild). Hector (field crew — praised for quality work on flood rebuild). Bill / Billy (project management — praised for sewage backup restoration and water damage work).
If you hire Madison Ave, ask for Bob directly and get his cell number. The reviews strongly suggest the quality of the experience is tied to Bob's personal involvement in the project. For mold specifically, request that a separate independent hygienist handle post-remediation clearance testing, and get the scope of the moisture source repair in writing before remediation starts.
Keep in mind
- They do both mold testing and mold remediation. When the same company tests and remediates, they have a financial incentive to find mold. Ask whether they will accept a third-party test result, or request that post-remediation clearance testing be performed by an independent hygienist.
- Their service area spans Long Island, all five NYC boroughs, and Westchester County. That is a large territory. If your property is on the far end of that range, confirm realistic response times for your specific location before signing.
- Mold remediation is one of many services they offer alongside water damage, fire restoration, roofing, plumbing, asbestos, demolition, and commercial construction. They are a general contractor that does mold work, not a mold-only specialist.
- The owner did not respond to either of the two recent negative reviews. No owner response on negatives means you cannot gauge how they handle complaints publicly.
