Chimney Inspection

We've used three different chimney companies over the years. Seattle Chimney Pros is by far the best. They showed up on time, explained everything, and the creosote removal was thorough.

Had an emergency leak during a rainstorm. Called Seattle Chimney Pros and they were at my house within 2 hours. Fixed the crown and flashing the next day. The real deal!

Our gas fireplace hadn't been serviced in years. They did a full maintenance check, replaced a faulty valve, and now it runs perfectly. Fair pricing with no upselling.

Gas Fireplace

The team rebuilt the top section of our 80-year-old chimney. The brickwork is flawless — you can't even tell which part is new. True craftsmen.

We had our chimney waterproofed before the rainy season. No leaks all winter — first time in 10 years. Wish we'd found them sooner. Highly recommend!

Our old clay liner was crumbling. They installed a stainless steel liner and the difference in draft is incredible. Job done right the first time.

Frequently Asked Questions

Why is chimney moisture worse on Mercer Island? +
Mercer Island is completely surrounded by Lake Washington, creating constant elevated humidity from all directions. Unlike mainland properties that may have a dry side, Mercer Island chimneys absorb moisture from every direction year-round. This makes marine-grade waterproofing and premium materials essential — not optional — for every chimney on the island.
How much does chimney service cost on Mercer Island? +
Given the premium expectations and multi-fireplace homes, Mercer Island chimney services range from $149 for a single-system inspection to $799-$1,200 for comprehensive multi-fireplace assessment. Custom copper cap installation runs $800-$2,500. Premium masonry restoration ranges from $2,000-$15,000 depending on scope. Marine-grade waterproofing runs $500-$1,000 per chimney.
Can you install copper chimney caps on Mercer Island? +
Absolutely — copper caps are one of our most requested items on Mercer Island. Copper develops a beautiful patina over time that complements luxury architecture, and it offers exceptional corrosion resistance in the island's humid environment. We custom-fabricate copper caps to fit your specific chimney dimensions.
My Mercer Island home has 5 fireplaces — can you service all of them? +
Yes, this is our specialty. We regularly service Mercer Island homes with 3-5 fireplace systems in a single visit. Each system gets a full independent assessment — whether wood-burning, gas insert, linear gas, or outdoor fireplace. You receive one comprehensive report covering every system in your home.
What materials do you use for Mercer Island chimney repairs? +
Only premium materials: hand-selected matching brick, custom-colored mortar, copper or marine-grade stainless steel flashing and caps, breathable marine-grade waterproofing sealant, and high-performance crown coatings. Every material is chosen for longevity in Mercer Island's demanding moisture environment and aesthetic compatibility with your home.
Is marine-grade waterproofing really necessary on Mercer Island? +
Essential. Standard waterproofing products are inadequate for Mercer Island's year-round lake humidity. We use marine-grade breathable sealants that block liquid water penetration while allowing trapped moisture vapor to escape. This prevents the freeze-thaw damage cycle that destroys unprotected masonry. Reapplication every 5-7 years maintains protection.
Do you provide pre-sale chimney inspections on Mercer Island? +
Yes, and they're especially important given Mercer Island's high property values. A comprehensive multi-fireplace inspection report demonstrates to buyers that every system has been professionally assessed and maintained. In Mercer Island's premium market, a clean chimney report supports your asking price and prevents last-minute negotiation over chimney concerns.
Can you work on outdoor fireplaces and chimneys on Mercer Island? +
Yes. Many Mercer Island homes feature outdoor fireplaces and fire pits as part of their outdoor living areas. These systems face even more direct weather exposure than interior chimneys and need regular maintenance. We service outdoor fireplaces, pizza ovens, and chimney structures throughout Mercer Island.

Mercer Island's unique geography as an island in the center of Lake Washington creates chimney conditions unlike anywhere else in the region. With water on all sides, the humidity level is consistently elevated — masonry absorbs moisture from the ambient air year-round, not just during rainstorms. This persistent moisture exposure demands the highest quality waterproofing, premium materials, and expert craftsmanship. At Seattle Chimney Pros, we bring the specialized knowledge and materials that Mercer Island's luxury homes require, from marine-grade waterproofing sealants to custom copper chimney caps.
The homes on Mercer Island represent significant investments — often $2-5 million or more — and chimney work must match the quality of the property. A poorly executed repair doesn't just look bad; it can reduce property value and create long-term moisture damage. Our chimney repair and restoration work on Mercer Island uses premium materials: hand-selected matching brick, custom-colored mortar, copper flashing, and marine-grade stainless steel components. Every repair is designed to be invisible and lasting.
Many Mercer Island homes feature 3-5 fireplace systems — from a grand masonry fireplace in the great room to gas fireplaces in the master suite, guest rooms, and outdoor living areas. Each system requires independent inspection and maintenance. We provide comprehensive multi-system service during a single visit, with a detailed report covering every fireplace and chimney in your home — the thorough, efficient approach that Mercer Island homeowners expect.
