Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterChimney Cleaning in Renton, WA
Chimney cap and crown work in Renton typically runs $285-$1,850 depending on whether we’re sealing surface cracks or replacing a full concrete crown and installing a multi-flue cap. The Boeing-era homes in the Highlands, built from the 1940s through the 1960s, left behind thousands of masonry chimneys now pushing 70-80 years old with original crowns that have never been touched. Our crews serve Renton from our Seattle office, and we carry Gelco and Olympia Chimney caps on the truck so most jobs finish in a single visit. Call (253) 323-5667 for a written estimate before any work starts.
Why Renton Homes Are Different
Renton sits in a valley at the south end of Lake Washington, and that geography traps maritime moisture against chimney masonry for seven months of the year. The Highlands neighborhood was built out heavily after WWII to house Boeing workers, leaving a dense concentration of 1940s-1960s ranch and cape-cod homes with original masonry fireplaces that were rarely relined or properly updated. Those chimneys are now 60-80 years old, and the persistent wet winters push homeowners to burn fires with incompletely seasoned wood, accelerating heavy creosote accumulation and mortar deterioration. The elevation change between the valley floor near the Boeing plant and the hillside Highlands also creates significant wind-pressure variation that can cause downdraft problems and force combustion gases back into living spaces.

Before
AfterChimney Cap & Crown in Renton
Renton’s wet maritime climate and its concentration of 60-80-year-old Boeing-era chimneys make cap and crown work our most frequent repair call in the city. Original concrete crowns on these Highlands homes have endured decades of freeze-thaw cycling and moisture penetration, and without a proper cap, flue liners fill with water that accelerates spalling and mortar decay. We install Chimney Cap & Crown systems using Gelco and Olympia Chimney materials sourced through our Haven buying network.
Crown Repair
Signs you need it
Hairline cracks spreading across the crown surface, pieces of concrete flaking off, or water pooling on top after rain instead of running off.
What it costs in Renton
Crown repair in Renton typically runs $285-$650 for crack sealing and resurfacing, while full crown replacement ranges $850-$1,850 depending on chimney width and access.
How we do it
We grind out cracked areas, apply a bonding agent, and pour new crown mix sloped to shed water, then document the finished slope with photos under Haven Standard Clause 4.
Cap Installation
Signs you need it
Water dripping into the firebox, birds or debris visible in the flue, or rust streaks running down the chimney face from a missing or deteriorated cap.
What it costs in Renton
Single-flue cap installation in Renton runs $180-$340, while multi-flue caps covering the full crown range $320-$580 installed.
How we do it
We measure the flue or crown footprint, select a stainless or copper cap from our Gelco and Olympia Chimney inventory, and secure it with masonry screws and high-temp sealant.
What Chimney Cap & Crown Costs in Renton
| Item | Typical range in Renton |
|---|---|
| Single-flue cap installation | $180-$340 |
| Multi-flue cap installation | $320-$580 |
| Crown crack repair / coating | $285-$650 |
| Full crown replacement | $850-$1,850 |
Can a cracked crown be repaired, or does it always need replacement?
Cracks under 1/8 inch with solid underlying concrete can be sealed and coated; deeper cracks or spalled surfaces require full replacement to prevent water intrusion into the chimney structure. Call (253) 323-5667 and we’ll show you exactly what your crown looks like on camera.
How long does a new chimney crown last in Renton’s climate?
A properly poured crown with correct slope and overhang lasts 20-30 years even in Renton’s wet winters; a cheap patch without proper slope often fails within 2-3 years. We warranty our crown work under the 365-Day Done Right Promise.
Chimney Liner & Rebuild in Renton
The Highlands’ 1950s clay-tile flue liners have spalled and cracked from decades of moisture cycling, and a brush-only cleaning misses damage that a camera inspection almost always reveals. Renton’s combination of wet winters and aged Boeing-era housing stock means we regularly find liners that have failed silently, risking carbon monoxide intrusion or chimney fires. We install Chimney Liner & Rebuild systems using DuraFlex and HeatShield materials.
Stainless Steel Liner
Signs you need it
Clay tile chunks in the firebox, visible cracks or gaps in the flue wall on camera inspection, or a smoky smell in the house when the fireplace is not in use.
What it costs in Renton
Stainless steel liner installation in Renton ranges $1,850-$3,400 for a standard straight flue, with prices climbing for multi-story or offset chimney configurations.
How we do it
We measure the flue with a video scan, drop a properly sized DuraFlex liner down the chimney, and connect it to the appliance or fireplace with a top plate and proper termination.
Partial Rebuild
Signs you need it
Multiple courses of spalled or missing brick above the roofline, a leaning chimney stack, or mortar joints eroded to the point that daylight shows through the wall.
What it costs in Renton
Partial rebuilds in Renton typically run $2,400-$4,800 depending on how many courses need replacement and whether the crown and cap can be salvaged.
How we do it
We scaffold the work area, remove damaged courses to sound masonry, lay matching brick with proper bond, and install a new crown sloped to shed water.
What Chimney Liner & Rebuild Costs in Renton
| Item | Typical range in Renton |
|---|---|
| Stainless steel liner installation | $1,850-$3,400 |
| Flexible liner for offset flue | $2,200-$3,800 |
| Partial chimney rebuild | $2,400-$4,800 |
| Full chimney rebuild | $6,500-$12,000 |
Does every old chimney in Renton need a new liner?
No; a camera inspection determines whether clay tiles are intact and properly sized for the appliance being vented, and we only recommend replacement when we can show you the damage. Call (253) 323-5667 for a free camera inspection and written estimate.
How disruptive is a chimney rebuild?
Partial rebuilds above the roofline keep the fireplace usable; full rebuilds may require temporary shoring and take 3-5 days, but we contain dust and debris with scaffold netting and daily cleanup. We provide a written schedule before starting any rebuild work.

We stock caps, liners, and repair materials from Gelco, Olympia Chimney, Famco, and Copperfield, procured through our Haven buying network to keep customer prices honest. Most cap and liner jobs in Renton finish in one visit because the parts are already on our trucks.
