In this blog post, Five Star Chimney Repair will share some tips on how to protect your chimney and keep it in great condition. Read on to learn more!

How To Protect Your Chimney

Protecting your chimney in Portland, Oregon, is an integral part of maintaining your home. Due to the damp climate in the Pacific Northwest, chimneys are susceptible to various issues, including animal infestations, moisture damage, and creosote buildup.

Winterize Your Chimney

Taking the time to properly winterize and care for your chimney can prevent costly repairs and keep you safe from dangerous conditions caused by improper maintenance.

Annual Cleaning and Inspection

One of the most important steps in protecting your chimney is performing a thorough inspection and cleaning each year. It is recommended that certified chimney sweeps be used for this task as they have the expertise necessary to inspect for potential issues and take proper corrective measures.


Five Star Chimney Repair‘s chimney sweep technicians will clear debris and blockages in the flue that could cause smoke or toxic fumes to enter your home. We will also inspect the interior of your chimney for signs of damage, such as crumbling mortar or rusting metal, which may need repair before use.


Our annual inspection also includes checking the firebox and damper for cracks or pitting.

Deter Animals From Your Chimney

Animals such as birds, squirrels, raccoons, and bats are known to build nests inside chimneys. If not addressed quickly, this can lead to clogged vents, smoke problems, strong odors within the home, and even structural damage over time.


A quality spark arrestor can be installed at least eight inches above the top opening of your chimney to prevent animals from entering. Also, an insulated cap or guard can be installed around it for further protection when not in use.

Waterproof Your Chimney

Moisture is another big problem in Portland’s climate that can seriously harm your chimney if not managed properly. Using a waterproofing sealant on both sides of masonry surfaces can protect against water infiltration.


Applying a silicone-based sealer can help keep mortar joints sealed tightly together regardless of sudden changes in temperature or weather conditions outside. 


Additionally, make sure there is no source near your fireplace where water can drip down directly into it, such as an air conditioner condensate line or roof gutter runoff spout that leads onto its roof surface.


There should also be ventilation across its surface so any built-up moisture can escape from the brick material used on its exterior walls.

Remove Creosote Buildup

Creosote buildup is a common issue with wood-burning fireplaces. If left unchecked for too long, it can cause an unpleasant smell inside homes and possibly flash fires.


Have a certified chimney sweep remove any build-up several times each season, depending on how often you burn wood logs inside it. More frequent cleanings might be necessary with heavier usage patterns!

Chimney Sweep in Portland
