Why BCI Group
Insulation and air sealing for Shrewsbury properties
Insulation is one of the few home upgrades that pays you back every month. We help Shrewsbury homeowners, builders and commercial owners plan work that lowers bills and makes rooms comfortable year-round.
Newer homes often have decent wall insulation but thin attics, leaky rim joists and cold rooms over garages, and those are the areas we target first.
Shrewsbury is minutes from our Westborough, MA headquarters, so estimates and follow-up visits are easy to schedule.
- Every major insulation type under one roof
- Fewer drafts and cold rooms
- Lower heating and cooling bills
- Air sealing before insulation, every time
Applications
Where Shrewsbury buildings need insulation most
Every area of a building has a different job, so each gets the material that suits it.
New construction
Spray foam, fiberglass and mineral wool installed to pass code and inspection.
Fireblocking and coatings
Code-required fireblocking and fire retardant coatings over exposed foam.
Rooms over garages
We seal and insulate the floor and kneewalls so bonus rooms stop running cold.Local homes
Shrewsbury homes and what they need
Shrewsbury mixes older homes near the town center and Lake Quinsigamond with large neighborhoods of mid-century capes and ranches and newer colonials built since the 1980s.
Shrewsbury runs from Lake Quinsigamond and the town center to newer neighborhoods off Route 140 and Route 20, so homes vary from early-1900s lake cottages converted to year-round use to large colonials. Converted cottages often need insulation added where there was none.
Central Massachusetts winters are colder and snowier than on the coast, and Worcester County's higher elevations add wind exposure, which makes attic air sealing and insulation especially valuable.

Insulation targets and incentives in Shrewsbury
Climate & code
Climate zone 5A targets
In climate zone 5A, which includes Shrewsbury, recommended attic levels are R-49 to R-60, well above what most homes built before the 1980s were given. Many Massachusetts towns have adopted the Stretch Energy Code or the Specialized Opt-in Code, which raise insulation and air-sealing requirements for new construction and major renovations.

FAQ
Insulation questions in Shrewsbury, MA
How long does an insulation job take?
Most homes take one to three days, depending on the areas involved. We give you a timeline with your estimate.
Do I need to leave home during the work?
Usually not for cellulose or fiberglass. For spray foam, we keep people out of the work area until it is safe to return.
Can insulation cause moisture problems?
Not when it is installed correctly. We check ventilation and moisture before recommending materials.
Where should I insulate first?
Usually the attic and the basement or crawl space. These areas often have the biggest air leaks and are the easiest to reach.
Do you work with builders?
Yes. We quote from plans and schedule around your inspections.
Will insulation help in summer too?
Yes. A well-sealed, well-insulated attic keeps upstairs rooms cooler and reduces air-conditioning costs.
How soon can you start a insulation project in Shrewsbury?
Shrewsbury is close to our Westborough, MA office, so estimates are usually easy to schedule. You'll get a start date with your written quote.
Do you also work in towns near Shrewsbury?
Yes. Besides Shrewsbury, we serve nearby communities such as Northborough, Westborough and Worcester, along with the rest of Worcester County.
