Quick and Professional Chimney Crown Repair in Boston
Reasons for crumbling masonry in a chimney vary, but one of the most common causes is a damaged crown. We repair damaged chimney crowns using high-quality tools and effective techniques.

Small Cracks in Your Chimney Crown? Let Our Professionals Repair It Fast!
The crown rests at the top of the chimney structure, acting as a protective shield against weather damage. It essentially prevents rain, water, and snow from entering the flue. This is important because water intrusion is highly destructive to a chimney’s structure and overall functionality. Complications begin when the crown itself gets damaged from general wear or freeze-thaw cycles.
If your chimney crown is deteriorating or missing entirely, we’re here to address the problem. We provide highly affordable yet effective chimney crown repair in Boston, ensuring that our clients have a chimney that’s well-maintained, efficient, and protected. Whether your entire crown needs to be replaced or there’s a small crack that needs to be sealed, you can count on us to do it the right way.

From Stainless Steel Crowns to Concrete Crowns, We Fix Them All!
Chimney crowns come in different configurations, each requiring different repair techniques.
We have the expertise to fix all kinds of crowns, whether they are made from stainless steel, stone, concrete, or clay tile. This is important as each material responds differently to high temperatures, weather changes, and age-related damage.
Using an incompatible kind of repair method can do more harm than good. This is also the reason why we always recommend reaching out to a professional like Bob’s Chimney for crown repair. A DIY approach by a beginner may fail to take these nuances into account and end up damaging the chimney further.


Signs You Need to Repair Your Chimney Crown ASAP
It’s not always obvious when chimney crowns are damaged. This often causes people to neglect them altogether. Here are the signs to look out for when it comes to crown damage:
01
Hairline Cracks
These cracks are caused by the natural expansion and contraction cycle. This causes thin fissures in the masonry.
02
Pieces of Masonry
Extensive spalling and masonry damage can cause large chunks of the bricks to fall out, leaving gaps in the structure.
03
Staining and Discoloration
Water damage often leaves behind stains not just on the chimney walls but your interior walls as well.
04
Water Leakage
Water drops leaking from your chimney are often a sign of severe moisture intrusion inside the chimney flue.
05
Improper Installation
A crown is supposed to have a slight slope to divert rainwater. If it’s rather flat, it needs to be reinstalled.
06
Aged Chimney Crown
The lifespan of a typical chimney crown is 20-50 years, after which it begins to deteriorate fast.

Why It's Important to Repair or Replace Old Crowns?
01
Sealing the top of your chimney and preventing moisture from making its way into the firebox, damper, and fireplace.
02
Protecting the chimney flue liner from getting damaged by redirecting water before it has the chance to infiltrate.
03
Increasing the overall lifespan of your chimney system by protecting it from weather and environmental damage.
04
Improving the performance of your chimney. A clean, unobstructed chimney is more efficient than a clogged chimney.
05
Maintaining a chimney crown is more cost-effective as compared to dealing with the hassle of costly repairs in the future.

Our Step-by-Step Process for Chimney Crown Repair in Boston, MA
STEP 01
Initial Chimney Inspection: We inspect the signs of chimney crown damage, like hairline cracks, moisture intrusion inside the chimney, or water damage to the brickwork.
STEP 02
Pre-repair Preparation: Before repairing, we perform a chimney sweep to prepare the surface. We use wire brushes or stiff poly brushes to remove dirt, debris, and creosote.
STEP 03
Minor Crack Repair: For filling small cracks, we apply a thick first coat of crown sealer. Once the drying time has passed, we apply a second coat to reinforce the protective layer.
STEP 04
Chimney Cap Repair (if needed) :Sometimes, water damage happens not because of a crown but a damaged cap. We replace worn-out caps and seal any exposed areas with caulk or refractory cement.
STEP 05
Final Chimney Inspection :Once we’ve fixed your chimney, we perform a final safety inspection to identify if the crown has been secured properly and if additional parts need to be repaired.

Chimney crown and cap difference?
A chimney crown is a sloped concrete slab that is located on top of the chimney stack. A cap, on the other hand, is a metal cap installed on the flue opening to keep rain, animals, and debris out of the flue.
How much does fixing a chimney crown cost?
The cost of chimney crown repair in Boston, MA, depends largely on the extent of the damage and the specific repair method required. Minor cracks may need simple sealing, while more severe deterioration could call for a full rebuild.
How often should a chimney crown be inspected?
We recommend inspecting and servicing your chimney at least once a year, depending on how often you use your fireplace or heating devices.
