How do I know if my chimney needs repointing vs full rebuild?

If the brick itself is sound and only mortar joints are eroded, repointing is the right call. If brick is spalling, leaning, or significantly displaced, a partial or full rebuild is needed. We assess in person — no guessing.

Do you pull the permits?

Yes. We pull all required building permits, coordinate with the local building inspector, and provide certificates of completion.

How long does the chimney work last?

A proper rebuild with quality brick and mortar lasts 60–100+ years. Repointing extends life by 25+ years before the next service.

Chimney in Stow, MA

A chimney contractor that knows Stow

Stow sits in MetroWest (Middlesex County), and projects here near Honey Pot Hill Orchards need to handle a specific blend of weather and soil. Stone walls outline original colonial farmland parcels. We've built chimneys throughout Pompositticut, Lower Village, and the rest of town with that local knowledge baked in.

JL Masonry has been serving Stow homeowners for over 15 years. Our crews understand the 1700s colonials and orchard-country farmhouses aesthetic that dominates Pompositticut, and we stock material samples that match Stow's historic vocabulary.

Common chimney problems in Stow

Mortar joints are crumbling and bricks are loose
Chimney crown is cracked, allowing water into the structure

Chimney is leaning or shows visible structural failure
