Masonry Waterproofing & Sealing in Unionville, Franklin, MA
Looking for masonry waterproofing & sealing in Unionville in Franklin, MA? Ultimate Boston Masonry is a licensed, insured, family-owned masonry contractor serving Franklin and the rest of Norfolk County from our Boston base. Franklin patios and walls go up on newer subdivisions where drainage planning is critical.
Housing in Unionville in Franklin includes a mix of Victorian, colonial, and mid-century homes, and wind-driven rain from nor'easters is what wears this masonry down. That is why our masonry waterproofing & sealing work starts with understanding what your building is made of — brick type, stone, mortar hardness, and drainage — before we price anything. Most masonry leaks are a joint, flashing, or crown problem first. We find and fix the entry point, then apply breathable silane/siloxane repellents that shed wind-driven rain without trapping moisture inside the wall.
Response time in Franklin: Estimates within 72 hours · Typical range $500 – $4,000

Local FAQ
Masonry Waterproofing & Sealing in Unionville, Franklin: questions answered
How much does masonry waterproofing & sealing cost in Unionville, Franklin, MA?
Most masonry waterproofing & sealing projects in Franklin fall between $500 – $4,000. Chimney sealing and small wall areas are at the low end; full-elevation repair plus sealing is higher. We give a free written, fixed-price estimate after an on-site look.
How quickly can you start masonry waterproofing & sealing in Unionville, Franklin?
Estimates within 72 hours in Franklin. Most projects are scheduled within one to three weeks, and safety hazards are prioritized.
Do I need a permit for masonry waterproofing & sealing in Franklin?
Minor repairs usually don't need a permit, but rebuilds, new structures, and tall retaining walls often do under the Massachusetts building code. We check with the Franklin building department and pull permits when required.
Which areas near Unionville, Franklin do you also serve?
Besides Franklin Center, Unionville, City Mills, we regularly work in nearby Brockton, Taunton, Attleboro, and every community within 45 miles of Boston.
Are you licensed and insured to work in Franklin?
Yes. Ultimate Boston Masonry is licensed, fully insured, and family-owned with 5 years of experience on Greater Boston brick and stone.
Should I waterproof my brick house?
Only after repairs. A breathable repellent helps exposed walls and chimneys shed rain, but it will not fix cracked joints or bad flashing.
What is the white powder on my brick?
That is efflorescence — salts carried out by moving water. It means water is getting into the wall and should be traced to its source.
