One-of-a-kind custom stonework — fireplaces, veneers, columns, mailboxes, water features and architectural details crafted to your vision. Proudly serving Hopkinton and the surrounding Metro West area.
When Hopkinton, Massachusetts residents need custom stonework done right the first time, they call YellowStone Masonry Group. With 50+ years working throughout the Metro West, we build for local conditions — harsh New England winters with repeated freeze-thaw cycles, heavy snow, and humid summers that crack, heave, and erode masonry over time.
That is why every custom stonework project we build in Hopkinton is engineered for our climate, using the right materials and proven techniques so it stays strong and beautiful for decades. From the first free estimate to the final cleanup, you work directly with a team that takes pride in every stone laid.
A plain exterior or yard with no focal point or character to set your home apart from the neighbors
Big-box, cookie-cutter kits that look fake and never quite fit the space you actually have
A dated brick fireplace or column that clashes with the rest of your updated home
Ideas you love online but no skilled mason to design and build them to last in New England
True custom design — we build to your space, your stone and your vision, not a one-size kit
Master craftsmanship in natural stone, granite and veneer that reads as authentic, not applied
Signature features: stone fireplaces, chimneys, veneer facades, columns, pillars, mailboxes and water features
Details engineered for New England weather so they hold up to freeze-thaw and moisture
A unique focal point that raises curb appeal and the perceived value of your home
Built by a 50+ year masonry team that takes pride in every stone laid
We talk through your vision, the space and your stone preferences, and sketch the concept together.
We measure, check the structure and substrate, and plan how the feature integrates with your home.
You receive an itemized estimate covering design, materials and build — clear and upfront.
Our masons handcraft the feature stone by stone, with proper backing and flashing, and finish spotless.
Stone fireplaces and chimneys, veneer facades, columns and pillars, mailbox surrounds, water features, outdoor kitchens, signage and architectural accents — if it can be built in stone, we can craft it.
Yes, when installed correctly. We use proper backing, moisture barriers, flashing and weeps so veneer sheds water and survives freeze-thaw for decades — the install matters as much as the material.
In most cases, yes. We source natural and manufactured stone and blend it to your existing masonry so the new feature looks original to the home.
