Why BCI Group

A tighter, quieter Grafton home with spray foam

Unlike loose insulation that can settle, spray foam bonds to the framing and stays in place for the life of the building. For Grafton homeowners, that means one job that keeps paying off in comfort and lower energy bills.

In older homes with irregular rafters and balloon framing, spray foam fills odd-shaped cavities and seals the open framing paths that let air move between floors.

Because Grafton is close to our Westborough office, we can usually see your property within days.

Local homes

Know your Grafton home

Grafton has historic homes around Grafton Common and in villages such as North Grafton and Fisherville, plus newer subdivisions built over the last few decades.

Grafton's villages, including North Grafton, South Grafton, Fisherville, Farnumsville and Saundersville, grew around mills on the Blackstone and Quinsigamond rivers, while newer neighborhoods spread out from Grafton Common. That mix means we often see antique homes and newer colonials on the same street.

Worcester County homes heated with oil or propane often see the fastest payback from sealing air leaks, because every gallon saved is money that stays in the house.

Recommended plan

How we would spray foam a typical older home in Grafton

Step 1

Find the bypasses

Balloon framing leaves open paths from basement to attic that we seal first.

Step 2

Foam the rim and sill

Old sill plates and band joists are sealed and insulated in one step.

Step 3

Treat the slopes and kneewalls

Finished attics and cape-style kneewalls get foam where batts never fit.

Step 4

Protect the structure

We check for moisture and ventilation so the old framing stays dry.

In newer homes, spray foam is most often used on roof decks, in bonus rooms over garages and at rim joists, where batts rarely seal well.

Climate & code

Climate zone 5A targets

Homes in Grafton sit in climate zone 5A, where ENERGY STAR suggests R-49 to R-60 in the attic. Settled or missing insulation is common in older buildings. 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

Spray Foam questions in Grafton, MA

Can you spray foam the walls of an existing home?

Open walls are easy to foam. For finished walls, dense-pack cellulose is usually a better choice, and we can recommend it.

Will spray foam make my house too tight?

A tighter house is more efficient, but it needs proper ventilation. We look at your ventilation and can recommend options when needed.

How long does a spray foam job take in Grafton?

Most residential projects take one to two days. We give you a timeline with your free estimate.

Do I need a fire-retardant coating over spray foam?

In many areas, exposed foam needs a thermal or ignition barrier to meet code. We tell you when it is required and can apply an intumescent coating.

Is spray foam safe once it cures?

Yes. Once the foam has cured and the area has been ventilated for the re-occupancy time the manufacturer specifies, it is inert. We keep people and pets out of the work area until then.

Open-cell or closed-cell spray foam in Grafton?

Closed-cell is denser, adds rigidity and resists moisture, which suits basements and roof decks. Open-cell costs less and absorbs sound in interior walls and attics. We recommend one after inspecting the space.

How soon can you start a spray foam project in Grafton?

Grafton 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 Grafton?

Yes. Besides Grafton, we serve nearby communities such as Millbury, Upton and Westborough, along with the rest of Worcester County.
