Question Answers

How does B & A Property Preservation handle water damage from a sewage backup in an Amherst home?

Sewage backup water damage requires immediate containment and sanitization. Our team first stops the source and safely removes contaminated water and materials. We then dry, disinfect, and restore affected structural elements—such as subflooring, wall framing, and baseboards. Depending on the extent, we may rebuild damaged sections and replace trim or cabinetry to return your home to a safe, clean condition.

Can you manage both the architectural design and construction for a new room addition?

Yes. We offer architectural design and project management as part of our services. For a room addition, we'll work with you on layout, permitting, and then handle all construction—including foundation, framing, roofing, siding, finish carpentry, flooring, and painting. This single-point coordination simplifies the process for homeowners.

Do you build modular or manufactured homes, and what does that process look like?

We do build modular and manufactured homes. The process involves site preparation, foundation work, coordinating delivery and assembly of the factory-built modules, then completing all on-site finish work: stairs, decks, trim, plumbing and electrical connections, and interior finishes. We handle everything from permits to final walkthrough.
