SERVING LEOMINSTER, MASSACHUSETTS
Home additions, ADUs, kitchens, baths, and multifamily renovation. A city built by manufacturing, with the housing stock to match, and that is the kind of building we know.
Leominster is the second largest city in Worcester County, with a population north of 43,000, and it has a history unlike anywhere else in our service area. It was the Comb City through the nineteenth century, with two dozen comb factories running by the 1850s. When natural horn ran short, celluloid replaced it, and the city pivoted into plastics. Samuel Foster brought modern injection molding here in 1931 and Foster Grant went on to sell twenty million pairs of plastic sunglasses in 1937. Earl Tupper founded Tupperware in Leominster in 1938. The city still carries the name Pioneer Plastics City, and the state has designated it a Gateway City.
All of that industrial history built houses, and those houses are what we work on.
Andrew Mercurio is a fourth-generation builder who came up in masonry and grew ARM Construction into a full general contracting company. He holds Massachusetts Construction Supervisor License #CS-093044, issued in 2011, and the company holds Home Improvement Contractor Registration #153199. Both are active and verifiable through the Commonwealth.
Kitchen and bathroom remodels are the largest share of the work here, and in the older parts of the city they are usually full gut renovations rather than updates. Home additions and ADUs and in-law suites are common in the residential neighborhoods where lots allow it. Garage, basement, and attic conversions come up frequently on the tighter lots closer to the center of the city. We also take two and three family and other multifamily work, which is covered further down.
We also build sunrooms and four season rooms, home remodels, custom masonry and stonework, decks and patios, siding, and flooring. One company, one point of contact, from the first walkthrough to the final inspection.
This is the practical thing to understand before planning any project that adds a bedroom.
The developed parts of Leominster, to the north, south, and east, are served by city water and sewer. The western side of the city is a different story entirely. It is largely protected open space, and it does not have public water and sewer connections, which means properties out there run on private wells and septic systems.
That single distinction changes what is possible. On a sewered lot, an addition or an ADU is a straightforward construction project. On septic, Massachusetts sizes systems by bedroom count under Title 5, so the existing system has to be measured against the added load before a design is finalized. If it will not carry it, the project becomes a septic upgrade plus an addition, which is a materially different budget.
There is a second layer on the western side. Leominster maintains a Water Supply Protection District as a zoning overlay, and properties within it face additional land use requirements. The city also sits within the Wachusett Reservoir watershed, where state rules can apply near tributaries and surface water.
None of this is unusual for this part of the county. It is simply the kind of thing that costs weeks if it turns up at permitting rather than at the first site visit.
A manufacturing city builds a lot of housing, and Leominster built a great deal of it. Much of the older stock near the center and along the older streets went up between the 1870s and the 1930s, during the comb and plastics eras, and a substantial share of it is multifamily, two-family and three-family rather than single.
We work on those buildings, and we take multifamily projects. That is worth stating plainly, because a lot of remodeling companies will not. Multifamily renovation is not simply larger single-family work. Fire separation between units, means of egress from upper floors, and the code requirements that apply to rental dwelling units all change the job, and doing it correctly requires a Construction Supervisor License and someone who understands what shifts when a building holds three units instead of one. Whether you live in one unit and rent the others, own the building outright, or own several, the conversation starts the same way.
Those houses are solid and they are also a century old, which means opening a wall here produces a familiar list. Knob and tube wiring. Electrical service sized for a household with a radio and an icebox. Cast iron waste lines at the end of their service life. Galvanized supply pipes narrowed by corrosion. Plaster over lath rather than drywall. Framing on irregular spacing that will not line up with a modern cabinet run. Little or no insulation in the exterior walls, which is why a re-side is such a good opportunity here.
Two legal considerations come with housing this old, and they matter more on rental property. Federal lead-safe work practices apply to renovation disturbing more than six square feet of painted surface indoors or twenty square feet outdoors in pre-1978 housing, which covers essentially all of it. And Massachusetts requires that a pre-1978 property occupied by a child under six be deleaded or brought under interim control, an obligation that sits with the owner on rental property regardless of who lives there. A new owner has 90 days from taking title to comply. There is also a state deleading tax credit, up to $1,500 per unit for full compliance and up to $500 per unit for interim control, carrying forward up to seven years. Per unit is the operative phrase on a three-family building, and a lot of owners never find out about it.
Old flooring deserves the same care. Nine-inch vinyl tile and the black mastic beneath it, standard from roughly 1948 through the 1970s, frequently contains asbestos, and Massachusetts regulation requires anyone removing floor tile and mastic to presume it does unless testing says otherwise. Our flooring page covers what that means before a demo day starts.
Any project that changes the footprint or the structure of a house in Leominster needs a building permit from the city, plus electrical, plumbing, and mechanical permits depending on scope. Work near wetlands goes to the Conservation Commission. Properties on septic involve Board of Health review of wastewater capacity, and properties in the Water Supply Protection District carry additional requirements.
We handle all of it. We pull the permits, coordinate the inspections, and deal with the city and any state review the project requires, so you are not the one filling out applications or tracking down a sign-off.
Sterling borders Leominster to the south and shares much of the same septic and watershed picture. Princeton sits southwest and is where we are based. We also work in Holden, Worcester, West Boylston, Boylston, Shrewsbury, Westborough, Northborough, Southborough, and Grafton.

Here is what Leominster homeowners ask us most. If your question is not here, call us at (774) 249-0221.
It depends on where in the city you are. Leominster's developed areas in the north, south, and east are served by city water and sewer. The western side of the city is largely protected open space and does not have public water and sewer connections, so properties there rely on private wells and septic systems. That distinction matters more than almost anything else on a project that adds a bedroom, because on septic the system has to be measured against Title 5 bedroom-count capacity before design is finalized. It is the first thing we check.
In most cases yes. Since February 2, 2025, Massachusetts allows one accessory dwelling unit by right on lots in single-family zoning districts statewide, up to 900 square feet or half the gross floor area of the main house, whichever is smaller, with no special permit and no zoning hearing. In Leominster the practical questions are whether your property is on city sewer or private septic, whether it falls within the city's Water Supply Protection District, and whether the lot has room after setbacks. On a sewered lot in a single-family district, an ADU here is straightforward.
Leominster grew as a manufacturing city, first as the Comb City and later as the birthplace of modern injection molding and the plastics industry, and much of its older housing went up during that period. Those homes are frequently more than a century old, often multifamily two-family or three-family, and typically carry knob and tube wiring, cast iron waste lines, plaster over lath, and little or no wall insulation. None of that prevents a good renovation. It does mean the walls should be opened by someone who has seen it before, and because the stock predates 1978, federal lead-safe work practices apply to most of it.
Yes. A large share of Leominster's older housing was built during the comb and plastics eras, and much of it is multifamily, two-family and three-family rather than single. We handle unit renovations, kitchens and baths, structural and foundation work, exteriors, and code compliance on those buildings. Multifamily renovation is not simply larger single-family work. Fire separation between units, means of egress from upper floors, and the code requirements that apply to rental dwelling units all change the job, and doing it properly requires a Construction Supervisor License. Andrew holds Massachusetts CSL #CS-093044.
Yes for most projects. Any addition, structural change, or conversion of unfinished space into living space requires a building permit from the City of Leominster, along with electrical, plumbing, and mechanical permits depending on scope. Properties in the city's Water Supply Protection District face additional land use requirements, and work near wetlands requires Conservation Commission review. Leominster also sits within the Wachusett Reservoir watershed, where state watershed rules can apply near tributaries and surface water. ARM Construction handles the permitting and the inspection schedule as part of the project.
