Brownstone & Landmark Restoration in Brooklyn & Manhattan

Brooklyn and Manhattan's brownstones are among the most beautiful — and most demanding — buildings to renovate in America. Plaster moldings, marble mantels, brownstone facades, and 150-year-old framing require a contractor who knows historic construction, not just new construction. M&M GC Contractor Inc has been restoring brownstones across Park Slope, Brooklyn Heights, Bed-Stuy, Harlem, and the Upper West Side since 2001.

We handle both sides of a brownstone project: meticulous exterior restoration — facades, cornices, stoops, and areaways — and complete interior renovations that bring the systems and layouts into the modern era while keeping the character intact.

Restoring 19th-century craftsmanship

Brownstone facades deteriorate from water, salt, and a century of patch repairs. We repair and repoint brownstone and masonry, restore cornices and window surrounds, rebuild stoops and areaway walls, and match historic profiles and details. On interiors, we preserve what's worth saving — plaster moldings, medallions, original doors and mantels — and rebuild everything else to modern standards.

The result is a home that reads as historic but lives as new: straight floors, quiet rooms, modern electrical and plumbing, and efficient heating, all behind restored original details.

Landmarks Preservation Commission approvals, handled

Many of our brownstone neighborhoods sit in historic districts, which means exterior work needs Landmarks Preservation Commission approval. We've prepared LPC applications many times and know what the commission looks for: appropriate materials, matching profiles, and historically sensitive methods.

We also coordinate the DOB permits that typically run alongside landmark approvals. One contractor managing both tracks keeps the project moving instead of bouncing between agencies.

Why homeowners and businesses choose M&M

• Licensed & insured general contractor operating in New York City since 2001 — over two decades of finished jobs, not promises.
• Big jobs only. We do full renovations, kitchens, bathrooms, brownstones, waterproofing, roofing, commercial and exterior work. We don't do handyman calls, which means your project gets a real crew and real project management.
• In-house crews for demolition, framing, drywall, flooring, electrical and plumbing — fewer subcontractors, fewer delays, one accountable team.
• NYC building know-how: DOB permits, co-op and condo board packages, Landmarks Preservation Commission approvals, occupied-building logistics — we've done it hundreds of times.
• Direct line to the owner. Call (917) 251-9318 and you talk to the people actually running your job.

How your project runs, start to finish

1. Consultation & site visit. We walk the space, listen to what you want, and flag anything structural, code-related, or permit-related up front.
2. Detailed scope & estimate. You get a clear written scope and a firm price — no allowances hiding the real number, no surprise change orders later.
3. Construction. Our in-house crews handle demolition through final finishes. The site stays clean, protected, and on schedule, with one point of contact throughout.
4. Final walkthrough. We go through every detail together before sign-off. If something isn't right, we fix it. That's the "built on trust since 2001" part.

Common questions

Does exterior work on my brownstone need LPC approval?

If your building is an individual landmark or in a historic district, most visible exterior work does. We assess your building's status and prepare the application with the documentation the commission expects.

Can you match my existing brownstone facade?

Yes. We repair deteriorated brownstone, repoint masonry, and match existing profiles, textures, and colors so repairs blend with the original facade.

Do you do full interior gut renovations of brownstones too?

Absolutely — many of our brownstone projects combine facade restoration with a complete interior gut: new systems, reconfigured layouts, and restored historic details.
