We’re growing the Abacus crew!

We’re currently hiring for two field positions:
• Lead Carpenter
• Site Supervisor

Both roles are based on our projects around Boston. We’re looking for people who know the work, take pride in doing it right, and can keep a job moving.

That’s some of our crew outside the shop on Old Colony Ave. We’ve been building in Boston for more than 20 years, and we’re looking for a few good people to join us.

Interested? Email [email protected] or call 617-922-9971.

Winter problems usually don’t start in winter.

A loose hose connection, a downspout sending water toward the foundation, a draft around a pipe or a stain under a roof deck can all be easier to deal with now than once Boston temperatures drop.

We put together 5 things worth checking around your house before the first freeze. Most of them you can check yourself in an afternoon.

And if you find something that doesn’t look right, give Abacus Builders a call. We work on Boston homes every day and can help you figure out what needs attention before winter.

Save this one for your fall weekend checklist.

A custom home doesn’t have to lose what makes it special just because the budget needs adjusting.

At 109 Old Rutherford Ave in Charlestown, we worked closely with the homeowner and architect to value engineer the original plans — preserving the standout design features while creating a more predictable budget and timeline.

The result: a ground-up new construction project with an open layout, thoughtful details, and a finished home that stayed true to the original vision.

Good planning early makes all the difference.

Taking advantage of the last good stretch of August from a South Boston roof deck.

And the view isn’t the only thing worth showing off. We worked with Viewrail on a custom floating stair leading up to a Dayliter roof hatch, making the access to the deck feel like part of the design, not an afterthought.

Because if you’re building a roof deck like this, getting there should look just as good.

Built with Boston families in mind.

This thoughtfully designed development transformed an underused 18,000-square-foot lot into six spacious condominiums, each featuring three to four bedrooms, open living spaces, generous storage, rear decks, off-street parking, and convenient access to the T.

From a complex zoning process to the final finishes, this project reflects what is possible when smart design, community collaboration, and experienced construction come together.

When one renovation quote comes in $60,000 lower than another, it is tempting to assume you have found the better deal.

But before you compare the totals, make sure you are comparing the same job.

A lower bid may include smaller allowances, more exclusions, no contingency for hidden conditions, or assumptions about the property that another contractor has already accounted for. Those costs do not necessarily disappear—they often return later as change orders.

Swipe through for six parts of a contractor’s proposal to review before choosing the lowest bid.

Save this for when you are collecting estimates—and send it to someone planning a renovation.

After a devastating fire gutted this corner three-decker on Columbia Road in South Boston, little remained beyond the structure itself. The windows were blown out, the openings boarded up, and the sidewalk surrounded by cones and fencing.

Abacus Builders brought the property back from the studs up—rebuilding the structure, exterior, windows, mechanical systems, interiors, and finishes. Completed in 2021, all three units were restored to condo-quality standards, including a roof deck off the top floor.

These three photos tell the story of the same corner: how the building once stood, what the fire left behind, and what stands there today.
