Brick and Mortar Chimney Repairs

Fixing bricks in chimney

The bricks and mortar that make up your chimney’s exterior naturally wear down with age. Rain and moisture cause the mortar to weaken, which leads to shifting bricks or open gaps. Tuckpointing and brick replacement are common repair solutions.

These repairs restore both function and appearance.

Tuckpointing: removes and replaces old mortar

Brick replacement for broken or spalling bricks

Surface sealing to resist future water damage

Matching materials for a seamless repair look

Prevents structural instability or collapse

Chimney Crown and Cap Repairs

Bad chimney crown

At the top of the chimney, the crown (concrete surface) and cap (metal cover) serve as your first line of defense. Cracks or deterioration in either of these can allow water to seep into the bricks below.

Repairing these components is a priority in any full exterior chimney restoration.

Fill or resurface cracked chimney crowns

Replace rusted or missing chimney caps

Add mesh to keep out debris and animals

Ensure proper slope to shed water off crown

Improve long-term chimney durability and ventilation

Chimney Flashing and Waterproofing

Chimney lashing and waterproofing

Flashing is the metal barrier where your chimney meets the roof. When this fails, water can seep into your attic or walls. In addition, applying a breathable waterproofing seal to your chimney’s surface can greatly reduce future damage.

These upgrades protect your home’s interior and exterior simultaneously.

Repair or replace step and counter flashing

Seal flashing seams with waterproof caulk

Apply masonry water repellent to entire chimney

Use vapor-permeable sealers that let bricks breathe

Prevent interior leaks and mold growth

Frequently Asked Questions about Exterior Chimney Repair

How do I know if my chimney needs exterior repair?

Look for cracks, missing mortar, leaning structure, or water stains. Annual inspections can catch problems early.

What is tuckpointing and why is it important?

Tuckpointing involves removing damaged mortar and replacing it to strengthen the chimney and prevent water leaks.

Can I repair the exterior of my chimney myself?

Small jobs like caulking or sealing may be DIY-friendly, but brickwork, flashing, and crown repairs should be done by professionals.

Basic mortar repairs start around $300–$800. Full masonry restoration or crown rebuilds can range from $1,000 to $3,000+.

How often should I waterproof my chimney?

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.
