Chimney Crown Repair

Chimney Crown Repair

When a crown is damaged, water can seep in and cause serious internal damage. Repairing a chimney crown may involve sealing surface cracks, resurfacing the crown, or replacing it entirely if the damage is severe.

A well-repaired crown redirects water away from the flue and masonry, keeping the system dry and safe.

Filling hairline cracks with crown sealant

Resurfacing with a waterproof concrete coating

Rebuilding sections with crumbled edges

Re-sloping the surface for better drainage

Adding a protective chimney cap on top

Metal Chimney Crown Repair

Metal Chimney Crown Repair

Some chimney crowns are built from metal, particularly on prefabricated fireplaces. These metal crowns can rust or pull away from the chimney structure, creating gaps for water to enter.

Proper repairs often involve replacing the metal or sealing seams to restore a watertight fit.

Repairing seams with high-temp caulk

Replacing rusted or bent metal flashing

Anchoring loose edges to prevent leaks

Painting or coating to resist corrosion

Installing proper overhang for water runoff

Fireplace Crown Repair

Fireplace Crown Repair

The fireplace crown is often confused with the chimney crown, but both serve similar functions depending on the design of the chimney system. A fireplace crown repair focuses on sealing cracks, restoring edges, and ensuring the top of your fireplace remains protected.

This repair helps maintain airflow, safety, and the structural integrity of your fireplace setup.

Inspecting for deep cracks or erosion

Applying masonry repair mix to fill gaps

Smoothing surface and adding water sealant

Adjusting slope to shed water efficiently

Installing drip edge to direct rainwater away

Frequently Asked Questions about Chimney Leaking Water

Why is my chimney leaking water when it rains?

Most likely due to damaged flashing, a cracked crown, or a missing chimney cap that allows rainwater in.

Can a leaking chimney cause mold?

 Yes, consistent moisture creates an ideal environment for mold to grow inside your walls or attic.

How much does it cost to repair a leaking chimney?

Costs vary but usually range from $200 for minor flashing fixes to over $2,000 for major masonry repairs.

 What is chimney flashing and why is it important?

Flashing is the metal seal between your chimney and roof. It prevents water from entering the joint area.

How do I know if my chimney cap is damaged?

Look for visible rust, dents, or missing pieces. You may also notice increased moisture or pests inside the flue.

Can a chimney leak be fixed from inside the house?

Not usually. Most chimney leaks require exterior repairs to flashing, masonry, or the crown.

Should I waterproof my chimney?

Yes, applying a breathable waterproof sealant can help prevent future leaks.

Will insurance cover chimney leak repairs?

It depends on your policy and the cause of the leak. Gradual wear is often not covered.

How often should I inspect my chimney?

At least once a year, ideally before winter. Inspections can catch leaks before they cause serious damage.

These guys are pros.The people in the office pick up the phone (unlike many other contractors) and are straightforward and friendly. The crew explained my options and were very clear about everything they were doing. The boss (over the phone) cleared up any issues I had and did everything to have me as a happy customer.

How we work:

Step#1
Contact us
You're not sure if you need chimney services, or what to expect if you do. It's normal to have a lot of questions about chimney services- after all, it's not a service that most people need on a regular basis. That's why we offer free estimates and consultations so that you can get all your questions answered before moving forward with any work. We understand that your satisfaction is our number one priority, which is why we work hard to provide quality chimney services that meet your needs and expectations. We want to make the process as easy as possible for you, from start to finish!
Step#2
Proposal
You have a problem that needs to be fixed but you're not sure how or where to start. It can be tough to know where to start when it comes to fixing a problem, especially if you're not familiar with the topic. We're here to help. We'll do a full evaluation of what needs done and how it can be accomplished. We'll give you our proposal including plans, timelines for completion as well as the guarantee that if any issues arise during this process we have an answer or solution at hand!
Step#3
Construction
It's stressful to have people in and out of your house all the time. And it's even more stressful when you're not sure what they're doing or when they're going to be done.  It's hard enough keeping your sanity with construction going on day and night, but then to have to worry about the clean-up crew coming? Ugh. We take care of everything for you so that you can relax and enjoy your new space without any stress. You don't have to lift a finger except to tell us what you want. We'll work around your schedule, do all the dirty work, and leave your home just as clean (or cleaner) than when we found it.
