Looking for masonry waterproofing & sealing in Lexington, MA? Ultimate Boston Masonry is a licensed, insured, family-owned masonry contractor serving Lexington and the rest of Middlesex County from our Boston base. Lexington's colonial homes and stone walls need repairs that look like they were always there.

Housing in Lexington includes granite stoops, brick chimneys, and stone garden walls, and road salt and plow damage every winter 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 Lexington: Estimates within 24 hours · Typical range $500 – $4,000

Local FAQ

Masonry Waterproofing & Sealing in Lexington: questions answered

How much does masonry waterproofing & sealing cost in Lexington, MA?

Most masonry waterproofing & sealing projects in Lexington 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 Lexington?

Estimates within 24 hours in Lexington. Most projects are scheduled within one to three weeks, and safety hazards are prioritized.

Do I need a permit for masonry waterproofing & sealing in Lexington?

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 Lexington building department and pull permits when required.

Which areas near Lexington do you also serve?

Besides Lexington Center, East Lexington, Countryside, we regularly work in nearby Waltham, Framingham, Natick, and every community within 45 miles of Boston.

Are you licensed and insured to work in Lexington?

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.
