New England Weather

New England Weather Is Tough on Chimney Masonry

From freezing winters to heavy rain and swinging temperatures, chimneys in Massachusetts and Southern New Hampshire take a beating every year.

Water gets into small cracks in brick and mortar. When temperatures drop, it freezes and expands, pushing the masonry apart. Each freeze-thaw cycle widens the cracks, loosens bricks and wears down mortar joints.

Small cracks today can become major masonry repairs tomorrow. Fixing deterioration early preserves more of your existing chimney and can help you avoid a costly rebuild.

“This past winter the outside of our chimney took a beating — bricks had split, mortar was cracking/falling out, and the flashing was lifting… Dave (the owner) and a member of his crew came out and performed an extensive inspection top to bottom, taking pictures and testing for any potential leaks and areas of weakness.”

Chimney Masonry Repair FAQs

Answers to common questions about chimney masonry repair. Still have a question? Call us at 978-685-0609.

Why do chimneys deteriorate so quickly in New England?

Freeze-thaw cycles. Rain and snow soak into brick and mortar, then freeze and expand when temperatures drop. Repeated every winter, this cracks bricks, loosens mortar and damages the crown faster than in milder climates.

What is repointing (tuckpointing)?

Repointing is the process of removing worn or damaged mortar from between the bricks and replacing it with fresh mortar. It restores the chimney's strength and keeps water out. Tuckpointing is a closely related technique, and the terms are often used interchangeably.

What causes loose or missing mortar?

Age, weathering and moisture are the most common causes. Water that gets into the joints freezes and expands, breaking the mortar down over time. Problems inside the chimney, like moisture buildup from a damaged liner, can speed this up.

Can cracked or spalling bricks be repaired?

Yes. Damaged bricks can be removed and replaced, and we match your existing brick as closely as possible. If damage is widespread, a partial rebuild may be the better long-term fix.

Can you repair just the chimney crown?

Yes. Depending on the damage, we can seal cracks with CrownCoat, CrownSeal or CrownSafe, or build a new crown. We'll recommend the right option during your estimate.

How do I know if my chimney needs to be rebuilt?

A rebuild may be needed if the chimney is leaning, has severe brick deterioration, extensive mortar loss or damage in several areas. We'll give you an honest assessment of whether repairs or a rebuild make more sense.

How much does chimney masonry repair cost?

It depends on your chimney: its height, how much damage there is, the materials needed and how easy it is to access. The best way to get an accurate price is a free repair estimate, where we inspect the masonry and give you a clear breakdown of costs.

How long do masonry repairs take?

It depends on the size of the job and the weather. Small repairs can often be done quickly, while larger repairs and rebuilds take longer. We'll give you a timeline with your estimate.

Do you offer chimney waterproofing?

Yes. We apply a breathable water repellent that keeps rain out of the masonry while letting trapped moisture escape. It's a cost-effective way to protect your chimney after repairs.

Do you remove chimneys?

Yes. If a chimney is no longer needed or is beyond repair, we can safely take it down, partially or completely.
