Trusted By Our Community

Onyx miraculously saved the original 1897 floral tiles in my South End brownstone. They matched missing pieces so perfectly even the historical commission approved. Two winters later, no cracks from freeze-thaw cycles.

Our Cambridge triple-decker's tiny bathroom is now a spacious shower with built-in seat and grab bars that look like art deco decor. The waterproofing held up when our upstairs neighbor's pipe burst last winter.

The radiant heated floors in our Newton Colonial's new bathroom make Boston winters bearable. Onyx sourced stunning blue granite that echoes our backyard pond and stands up to our kids' splashing.

After my father's stroke, Onyx transformed our Quincy ranch's bathroom into an accessible space that doesn't feel clinical. The curbless shower and motion-activated lighting have prevented several falls.

Our Beacon Hill condo's awkward 1980s bathroom is now a period-appropriate masterpiece with modern function. They replicated original molding details while adding hidden storage we desperately needed.

The glass shower enclosure Onyx installed in our Brookline Arts and Crafts home stays crystal clear despite hard water. Their ventilation solution finally stopped the peeling paint we'd battled for years.

FAQ

Your Questions, Our Expert Advice

How do you handle plumbing in older Boston homes?
We carefully evaluate existing systems and recommend either preservation or replacement with freeze-resistant PEX piping. For historic properties, we maintain original layouts while upgrading functionality.
What's your timeline for a typical Cambridge renovation?
Most complete renovations take 3-5 weeks. Victorian homes may require additional time for custom millwork replication and historic commission approvals.
Do you work with small Back Bay bathrooms?
Absolutely. We specialize in space-maximizing designs for compact bathrooms, using features like wall-mounted vanities and recessed storage to maintain historic proportions.
