General Contractor & Damage Restoration | New Amsterdam Construction, Putnam Valley

For sump pump failure flooding or sewage backup water damage, we start with a site inspection to gauge the extent of water intrusion. We extract standing water, set up industrial drying equipment, and treat affected areas to prevent mold and bacteria. For sewage backups, we follow strict biohazard protocols. We also assess underlying causes, such as drainage issues around the home or aging sump pumps, and can install a backup system or recommend repairs to prevent future floods. Our goal is to restore your home quickly and safely, coordinating with your insurance company throughout the process.

Yes, we construct guest houses and accessory dwelling units (ADUs) throughout Putnam Valley. We handle the full process, from permitting and site planning through foundation work, framing, and finishing. Whether you want a one-bedroom cottage for a family member or a larger detached structure near Oscawana Lake, our team has the experience to design and build a functional, code-compliant space that fits your property's layout and your budget.

For historic homes in areas like Peekskill Hollow, our fixture refinishing restores old hardware, light fixtures, and doorknobs to their original luster using techniques like stripping, polishing, and lacquering. Our plaster mouldings and castings are done by hand, matching period details for crown mouldings, ceiling medallions, or wall trim. We use traditional methods and materials to preserve the character while ensuring durability. This service is ideal for owners who want to maintain the historic integrity of their home during a remodel or after water damage repair.
