Exterior Painting across Blackstone, Massachusetts.

Blackstone's houses come from very different periods, and their exteriors show it. Mill-era housing came first: the Blackstone Manufacturing Company opened its cotton spinning mill in 1809, and the worker housing it built was mostly wood-framed tenements of two to six units, originally sided in clapboard. Much later, the town's 2019 Housing Production Plan records rapid population growth in the 1980s, and Census estimates count about as many surviving homes from the 1960s as from the 1980s. Each period brings its own exterior painting problems.

Clapboard in the National Register districts

Four National Register historic districts touch the town. The Blackstone Manufacturing Company district runs roughly along Main, County, Canal, Church and School Streets, and the National Park Service lists its styles as Greek Revival, Italianate and Queen Anne. The East Blackstone Village district along Elm Street holds fourteen residential buildings, mostly Greek Revival or Federal, with the oldest, the Seth Kelly House, dating to about 1760. Farnum's Gate and the multi-town Blackstone Canal district round out the list.

Wood clapboard of that age can carry many coats. Thick, old paint stacks crack across the grain and lift in sheets, and the wood underneath can be dry, split or soft at the bottom edges where water sits. Proper prep means scraping to a sound edge, feathering the transitions, replacing rotted boards with matching profiles, and priming bare wood the same day so it does not weather. Ornament on Italianate and Queen Anne houses, such as brackets and turned porch parts, takes the most hand work.

Do historic districts limit paint colors?

National Register listing on its own does not control what a private owner does. The National Park Service states that listing places no restrictions on what a non-federal owner may do with a property unless federal money is involved, and that it does not automatically create local historic district zoning. The town has a Historical Commission, which runs the historical museum at 23 Main Street. If you live in one of the listed districts and want to confirm whether any local rule applies to your project, the commission is the place to ask before choosing colors.

Mid-century and 1980s houses

Units built in the 1960s and the 1980s each make up about 17% of local housing. Depending on the house and on any re-siding since, a home from either decade might have wood clapboard, wood shingles, or a manufactured product such as hardboard, and each one fails differently. Shingles weather and cup, hardboard swells where its edges get wet, and wood clapboard peels where moisture moves through from inside. A walkaround before the estimate identifies the siding type and the cause of any failure, because painting over a moisture problem shortens the life of the new coat.

Residential lots in the town's R1, R2 and R3 zones start at 35,000, 65,000 and 120,000 square feet. Where a wall faces woods or sits under branches, it stays damp longer and grows mildew. Those sides get a mildew wash and a thorough rinse before priming, and trimming back branches that touch the house helps the new paint dry and last.

Lead-safe scraping and the painting season

About 62% of housing units here were built in 1979 or earlier, so many exteriors may carry lead in older layers. Scraping and sanding outside spreads chips into soil and garden beds unless the ground is covered and the debris is collected each day. Our lead-safe painting page outlines how that work is contained.

Most exterior paints need surface and air temperatures above a minimum, often around 35 to 50 degrees depending on the product, and dry conditions through curing. In central Massachusetts that confines exterior work to roughly spring through fall. Our post on painting a house exterior in November covers the late-season limits.
