Gerard Whelan grew up in the trade. His family ran a construction business, and after years working in it, he started Three Hills to build something of his own, with his own crew on every job from start to finish. He has a soft spot for older homes and historical work, the brick and stone that carries a piece of the area’s history. The name nods to the three hills Boston was first built on. Fitting, for a company that’s about leaving solid work behind for the towns and families it serves.

There’s no flat rate for masonry or foundation work. The price depends on the size of the job, the materials, and the condition of what’s already there. The only way to give you a real number is to see it in person, which is why we start with a site visit.
Yes. Three Hills is a registered Home Improvement Contractor (HIC #219738) and carries workers’ comp and liability insurance.
Often, yes. Many chimneys only need repointing or a new crown rather than a full rebuild, especially if the damage is limited to the mortar or the top. A rebuild becomes necessary when the structure itself is leaning, cracked through, or pulling away from the house. We’ll tell you which one you’re looking at after we see it.
It depends on the crack. Hairline cracks are common in New England homes from normal settling and freeze-thaw, and usually aren’t urgent. Cracks that are widening, horizontal, or stair-stepped through the block are worth a closer look, since they can point to a structural or water issue. When in doubt, have it inspected.
Yes, both. We handle new masonry as well as repairs and restoration on existing brick and stone, including matching the original materials so the work blends in.
