Building an outdoor fireplace is structural masonry work, not a kit assembly. We start with a reinforced concrete footing sized to the fireplace's weight, then lay concrete block or brick up to grade. From there we build the firebox with firebrick and refractory mortar, set the damper and smoke shelf, and run the chimney to the correct height above the roofline. Every outdoor fireplace builders Milwaukie OR project we take on follows IBC chimney clearances and ASTM masonry standards so the unit drafts properly and passes inspection.
Milwaukie's wet winters and clay-heavy soil are hard on backyard masonry. Water infiltration into mortar joints, spalling brick, and settling footings are the three failures we see most often on older fireplaces around Lake Road and Hector Campbell. If you've been searching for outdoor fireplace construction in Milwaukie that accounts for our actual climate, we design with a raised hearth, a proper crown, and a stainless cap. We also flash the chimney where it meets any structure and seal the firebox surround against driving rain.
A standard build covers everything from the footing to the cap. Add-ons like a pizza oven, gas log set, or matching seating wall are priced separately so you can see exactly what each upgrade costs before you commit.
Excavation below the frost line, reinforcing steel, and a poured concrete footing sized to the fireplace and chimney load. This is the part you never see and the part that decides whether the fireplace stays level for 30 years.
Concrete block laid with Type S mortar, a firebrick-lined firebox set in refractory mortar, and a properly built smoke shelf and damper. We size the firebox to your intended log length, typically 24 to 30 inches.
Your choice of natural stone veneer, cast stone, or brick, cut with a wet saw and set over a drainage plane. We tool the joints for a clean finish and match the mortar color to your home's existing masonry where possible.
A flue run to IBC code height above the roofline, a stainless steel cap with spark arrestor, and flashing where the chimney meets any structure. This is what keeps rain out and smoke moving up instead of into your face.
We pull the masonry permit with the city and coordinate the inspection. You don't have to chase paperwork or schedule the inspector. We build to code, we pass, and we hand you the signed-off documentation.
We tarp your landscaping, stage material on plywood, and sweep the site at the end of every workday. When we're done, the only thing left behind is the fireplace. No mortar splatter on the patio, no brick scraps in the grass.
We walk your yard, check setbacks against Milwaukie zoning, and mark the footprint with stakes and string. You'll see exactly where the hearth, chimney, and any seating wall will sit. This visit takes about 45 minutes, and we leave you with a written scope and a fixed price before any material is ordered.
Day one on site is excavation and forming. We dig below the frost line, typically 18 to 24 inches here, set reinforcing steel, and pour a concrete footing sized for the fireplace's dead load plus a chimney. The pour cures 48 to 72 hours before we lay the first block. This is the step that keeps the fireplace from settling.
We lay concrete block for the core, then build the firebox with firebrick and refractory mortar rated to 2,000 degrees. The smoke shelf and damper go in at this stage, and we set the firebox dimensions to match your intended log length, usually 24 to 30 inches. This is where a mason's level and mason's line earn their keep.
Once the core is up, we apply the finish: natural stone veneer, cast stone, or brick to match your home. We cut each piece with a wet saw and set it with a jointing tool for clean, consistent mortar lines. Veneer work adds three to five days depending on the pattern and the square footage of the face.
We run the flue to code height, install a stainless steel cap and spark arrestor, and flash the chimney against water intrusion. Then we let the mortar cure seven days before the first burn. We walk you through damper operation, ash cleanout, and the seasonal check you should do each fall before lighting up.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Used on every course of block and brick to keep the fireplace plumb and the joints consistent. A fireplace that's out of level by a quarter inch at the base will be visibly off at the chimney.
The wet saw cuts stone veneer and brick cleanly without chipping the face. The angle grinder with a diamond blade is what we use to grind out failed mortar joints during repointing work.
The trowel spreads mortar, the jointing tool finishes the joint profile, and brick tongs let us carry six to ten brick at a time without dropping them. Basic tools, used well, on every job.
We use these for block core and general masonry. For the firebox itself we switch to refractory mortar rated to 2,000 degrees, which is a different product entirely and not interchangeable.
Our primary suppliers for brick, block, and natural stone veneer in the Portland metro. Sourcing locally means faster delivery and a better color match when we're repairing existing masonry.
When the fireplace ties into a patio or seating wall, these are the paver lines we specify. They're rated for wet climates and hold their color through freeze-thaw cycles.
A 12-year-old brick fireplace that pushed smoke into the house on every burn. The smoke shelf was built flat instead of angled, and the flue was two courses short of code height. The owner had stopped using it entirely.
We rebuilt the smoke shelf, added two courses to the chimney, and installed a stainless cap. Draft measured correctly on the first test fire. Total job took three days and cost less than a third of a full replacement.
A bare concrete patio with a rusted steel fire pit that had survived two winters. The homeowner wanted a permanent fireplace with wood storage and a stone face that matched the house's existing brick trim.
We poured a footing at 24 inches, built the block core, and faced it in natural stone veneer with a wood storage alcove. The build took 16 working days. It passed inspection on the first visit and has been through two rainy seasons without a crack.
A fireplace that had settled about an inch and a half on one side, cracking the hearth and pulling away from the patio. The original footing was only 10 inches deep and sat on un-compacted fill.
We excavated around the footing, underpinned it with new concrete and reinforcing steel, and re-leveled the fireplace. The hearth was re-set and the crack repaired. Total cost was roughly 40 percent of a full rebuild.
Most of the fireplaces we're called to repair failed for one of four reasons. Here's what we see and how we correct it.
Ask a pro →We inspect the firebox, measure the flue against IBC height requirements, and check the smoke shelf geometry. In most cases we rebuild the shelf, raise the chimney, or add a cap that improves draft. The fix usually takes one to two days.
We grind out the failed mortar with an angle grinder, match the original mortar hardness, and repoint the joints with a jointing tool. Spalled brick gets cut out and replaced with a color match. Then we seal the veneer against further water infiltration.
We excavate around the footing, underpin it with new concrete and reinforcing steel, and re-level the fireplace. If the core has cracked, we rebuild the affected section. It's a bigger job than repointing, but it saves the fireplace.
We install a stainless cap with a spark arrestor, flash the chimney at the roofline, and treat the masonry with a breathable water repellent. If the damper is rusted, we replace it while we're on the roof. Most of these fixes are done in a single visit.
Most outdoor fireplace construction in Milwaukie Oregon runs $6,500 to $18,000 in 2026, with a simple brick hearth at the low end and a full stone fireplace with wood storage and a pizza oven at the top. Footing depth, veneer material, chimney height, and gas or wood-burning configuration drive the number. We give you a fixed price after the site visit, so there's no guessing.

Yes. Every fireplace we build is drawn to your patio, not pulled off a shelf. We've built angled fireboxes facing a seating wall, two-sided hearths, fireplaces with built-in wood storage, and units faced in stone veneer matched to the house. If you want a specific brick, a particular stone, or a gas log set, we'll spec it and build around it.
Plan on two to three weeks of on-site work for a standard fireplace, plus a week of cure time before the first burn. The footing needs 48 to 72 hours to cure, the veneer adds three to five days, and weather can push the schedule. We give you a start date and a finish date before we break ground, and we hit them.
