Old Denver Chimneys,Done RightChimney repair, relining and masonry for Victorians, Denver Squares and bungalows across the city
Denver's older neighborhoods were built with soft local brick and fireplaces designed to burn coal. Over a century later, those chimneys often have no liner, crumbling joints and tiny fireboxes that smoke when you try to burn wood. We restore them, convert them, or take them down safely during a remodel, and someone at Denver Chimney & Masonry picks up whatever the hour.

What century-old Denver chimneys need
Gentle mortar for soft brick
Early Denver brick is soft and porous. Repointing with hard modern mortar damages it, so we use softer lime-rich mixes.
A liner where there isn't one
Many chimneys from this era were built without flue tiles. A stainless or cast-in-place liner makes them usable again.
Decorative tops kept intact
Stepped and patterned brick crowns are relaid one row at a time so the street view stays the same.
Historic district review
Exterior work in Denver's landmark districts may need design review. We help with photos and specs.

Small fireplace, big smoke?
Is your fireplace really a coal fireplace?
Many Denver homes from the 1880s to the 1920s were heated by coal. Their fireplaces look charming but were built for a small basket of coal, not a stack of logs.
Shallow, narrow firebox
Often only 8–14 inches deep, too shallow for wood to burn cleanly.
Decorative tile or cast-iron surround
Ornate tile, a cast-iron insert or a small arched opening.
Smoke rolls into the room
Log fires push smoke out because the opening and flue were sized for coal.
The fix
A gas coal basket or compact insert keeps the antique look and works safely.

How we take a chimney out of an old house
Removing a chimney from a 100-year-old home takes planning. Here's the order we follow.
01 CHECK
What's venting?
We confirm the furnace, boiler or water heater doesn't still need the flue, or plan a new vent.
02 PLAN
Permits & support
We coordinate with your GC on permits, joists and any structural support.
03 REMOVE
Top down, by hand
Brick comes down in sections, with dust control and debris haul-away.
04 CLOSE
Patch & cap
Roof decking and shingles patched, or the remaining stack capped below the roof.

Is there really someone to talk to at night?
Yes. The line rings through to a person 24/7, holidays included. Loose bricks at the top, smoke inside, or water coming through gets a tech out without waiting for morning.
Will logs work in a fireplace built for coal?
Usually not well. Coal fireboxes are shallow and their flues are small, so wood fires tend to smoke. A gas coal basket, gas logs or a small insert paired with a correctly sized liner works far better.
Our flue was built without tiles. Should we worry?
It can be. Without a liner, heat and flue gases can reach wood framing through gaps in the brick. The NFPA 211 chimney standard expects a liner, and stainless or cast-in-place systems can be installed from the top in most chimneys.
What mortar should go on old Denver brick?
A softer, lime-rich mortar. Hard Portland cement mortar is stiffer than old soft brick, so over the years the old brick spalls instead of the joint.
Can you remove a chimney during our remodel?
Yes. We check that nothing still vents through it, coordinate permits and structural support with your contractor, take it down by hand with dust control, and patch the roof.
Do I need approval for chimney work in a historic district?
Visible exterior changes in Denver's designated landmark districts may need design review. Like-for-like repairs are often simpler. We can prepare photos and specs for the city.
Which neighborhoods do you serve?
All of Denver, including Capitol Hill, Highlands, Washington Park, Baker, Platt Park, Congress Park, Park Hill, Berkeley, Sloan Lake and Ruby Hill, plus Englewood and Lakewood.
