Chimney Repair & Rebuilds in Beaverton, OR — Built for Clay Soil & Heavy Rain
Expert masonry solutions for Washington County’s toughest chimney challenges.
At Portland Chimney & Masonry Inc., we repair and rebuild chimneys engineered specifically for Beaverton’s conditions. The region receives 41 inches of annual rainfall, nearly double the U.S. average, combined with Beaverton Series soil containing 25-35% clay. This combination creates a perfect storm: water intrusion from above, foundation heave from below.
Many chimney repairs fail because water intrusion and foundation movement are treated as separate issues. We treat them as one structural challenge that requires deep footings, premium waterproofing, and techniques proven across 40 years in this exact climate. The result: chimneys that don’t leak, don’t lean, and don’t fail.

The Beaverton Chimney Problem: Water From Above, Heave From Below
Most Beaverton homeowners don’t realize their chimney is fighting two enemies simultaneously. The first is obvious: 41 inches of annual rain, concentrated October through January, finds every crack and weak mortar joint. Water intrusion causes interior staining, accelerates mortar erosion, and can lead to structural failure within 5-10 years if left unaddressed.
The second enemy is invisible: Beaverton Series soil contains 25-35% clay. Clay expands when wet (winter) and contracts when dry (summer). A chimney foundation set at standard depth (12-18 inches) will heave and shift within 3-5 seasons, leaving you with a leaning chimney and cracked mortar.
The solution isn’t choosing between water defense and foundation stability. It’s engineering both.
We set every structural footing a minimum of 24 inches deep—well below the frost line—using reinforced concrete. We use premium masonry waterproofing, custom-fitted chimney caps, and specialized crown repairs designed to shed Beaverton’s heavy rain. This is why chimneys we rebuild in West Beaverton, Cedar Hills, and Murrayhill stay stable and dry for 30+ years.
Chimney Services For Beaverton Homes
Chimney Repairs & Rebuilds
For: Homeowners with visibly leaning chimneys, interior water stains, or mortar that’s crumbling faster than it should.
Read More
Why Beaverton makes it urgent: Beaverton’s clay soil expands and contracts with seasonal moisture, causing foundations to heave. A chimney that was plumb five years ago may be leaning now. Waiting another season means the problem gets worse—and more expensive. A leaning chimney is also a structural liability if you’re selling.
What we do: We don’t just replace bricks or patch mortar. We remove inadequate footings, auger to proper depth below the frost line (24+ inches), and rebuild with reinforced concrete and mortar matching. This stops the heave at the source.
Why it matters: A chimney rebuilt to proper foundation depth won’t lean again, even as Beaverton’s clay soil cycles through wet winters and dry summers. That’s why the chimneys we rebuilt 10+ years ago are still plumb today.
Chimney Inspections (Level 1 & Level 2)
For: Real estate buyers and sellers in Beaverton’s competitive housing market, and homeowners who haven’t had their chimney inspected in 3+ years.
Read More
Why Beaverton makes it urgent: A failed chimney inspection can derail a sale in Beaverton’s active market. Lenders require NFPA-compliant inspections before closing. Sellers who discover chimney problems late in escrow lose negotiating power. Buyers who skip inspections inherit expensive problems.
What we do: We use video scanning and full-flue evaluations to identify hidden damage—cracks, missing liners, creosote buildup, water intrusion—before they become deal-breakers. We provide NFPA-compliant reporting that lenders and title companies accept without question.
Why it matters: A Level 2 inspection costs $300-400 and takes 90 minutes. A chimney fire or structural failure costs $5,000-15,000 and can delay a sale by months. In Beaverton’s market, that’s the difference between closing on time and losing the deal.
Chimney Cleaning & Sweeping
For: Homeowners with wood-burning fireplaces or stoves who use them regularly (or plan to this winter).
Read More
Why Beaverton makes it urgent: Beaverton’s cool, damp climate causes creosote to build up 30-40% faster than in drier regions. Creosote is flammable. A chimney fire can reach 2,000°F and cause structural damage, roof fires, and code violations. Annual cleaning is the only prevention.
What we do: We sweep out soot, ash, and creosote buildup, then inspect for damage. We recommend scheduling before October (before the rainy season and before you need the fireplace).
Why it matters: A chimney sweep costs $150-250 and takes 1-2 hours. A chimney fire costs $5,000-10,000 in repairs, plus potential home damage and insurance complications. If you use your fireplace, this is non-negotiable.
Chimney Liner Installation & Relining
For: Homeowners in HOA-restricted neighborhoods (like Murrayhill, Westbrook, Cross Creek) who need chimney reinforcement but can’t do a full tear-out and rebuild.
Read More
Why Beaverton makes it urgent: Many Beaverton neighborhoods have strict HOA guidelines that prohibit exterior modifications. A full chimney rebuild requires architectural approval and often gets rejected. A chimney liner solves the problem invisibly—from the inside—without triggering HOA review.
What we do: We install stainless-steel liners and offer HeatShield® resurfacing to reinforce chimneys against water intrusion and improve draft. The work is done entirely inside the chimney, so no exterior changes trigger HOA review.
Why it matters: If you’re in an HOA neighborhood and your chimney needs reinforcement, a liner is often your only option. Trying to do a full rebuild without approval wastes time and money. A liner solves the problem in 1-2 days without HOA drama.
Masonry Restoration & Waterproofing
For: Homeowners with chimneys that are structurally sound but showing signs of age: stained mortar, efflorescence (white powder on bricks), or visible water damage inside.
Read More
Why Beaverton makes it urgent: Beaverton receives 41 inches of annual rain. Water finds every weak mortar joint and hairline crack. Once water gets inside the chimney structure, it accelerates deterioration exponentially. A chimney that looks “just old” today will be structurally compromised in 3-5 years if water intrusion isn’t stopped.
What we do: We repoint mortar joints (replacing old, weak mortar with new, strong mortar), seal the crown, and apply premium waterproofing to block water at the source. This stops deterioration and extends your chimney’s life by 20-30 years.
Why it matters: Waterproofing costs $1,500-3,000 and takes 2-3 days. Ignoring water intrusion costs $8,000-15,000 in structural repairs 5 years later. In Beaverton’s climate, waterproofing isn’t optional—it’s insurance against the rain.
Beaverton Chimney Permits: What You Need to Know
Navigating the permit process in the City of Beaverton can be confusing, but we handle it for you. Here’s what you need to know about the rules for chimneys and fireplaces in Beaverton, which are governed by the Oregon Residential Specialty Code (ORSC) and NFPA 211 standards.
The 3-2-10 Rule (Oregon Residential Specialty Code Section R1003.9)
Chimneys must extend not less than 2 feet higher than any portion of a building within 10 feet, but shall be not less than 3 feet above the highest point where the chimney passes through the roof. A minimum 2-inch clearance is strictly required between masonry chimneys and combustible materials. If your home is located on forest-zoned lands near the edges of Beaverton, a spark arrestor is legally required.
The Permit Process
For new chimney construction or full removal, a building permit is required. We submit the application through the Beaverton Building Division’s Electronic Permitting System (BEPS). Typical approval time is 5-10 business days. Once approved, we coordinate all inspections to ensure your chimney is built to code.

Frequently Asked Questions
Do I need a permit for a chimney repair in Beaverton?
It depends on the scope. A building permit is required for new chimney construction or full removal. Minor repairs above the roofline may not require a permit. If your property is part of an HOA, you’ll likely need architectural approval regardless. Contact the Beaverton Building Division at 503-526-2403 to confirm requirements for your specific project.
How do you handle the clay soil in Beaverton when building a new chimney foundation?
We set all structural footings a minimum of 24 inches deep, well below the frost line. This ensures the foundation is anchored in stable soil and won’t heave or shift during the seasonal expansion and contraction of Beaverton’s clay-heavy soil. The Beaverton Series soil contains 25-35% clay, which requires this deeper setting to prevent the post-heave issues common in the region.
My roof has a steep pitch. What is the chimney height limit?
According to the Oregon Residential Specialty Code (Section R1003.9), chimneys must extend at least 2 feet higher than any portion of a building within 10 feet, and at least 3 feet above the roofline. We handle all calculations to ensure your chimney meets these safety standards while providing an optimal draft.
What is the typical permit approval time for a chimney rebuild in Beaverton?
The typical approval time for a residential building permit from the Beaverton Building Division is 5-10 business days. We handle the submission through their electronic portal and manage follow-up to keep your project moving.
How often should I have my chimney swept in Beaverton’s climate?
We recommend an annual sweep and inspection for most homes using wood-burning systems. In our damp Pacific Northwest climate, creosote builds up faster because fires often run cooler. With Beaverton’s 41 inches of annual rainfall, regular maintenance is your best defense against chimney fires and water damage.
How do you handle HOA approval in communities like Westbrook or Cross Creek?
We review your HOA’s specific architectural guidelines and help prepare necessary documentation, including details on materials, mortar colors, and design. We are experienced in meeting the strict aesthetic requirements of Beaverton’s established neighborhoods. Many HOAs require submissions 30 days in advance, and we manage this timeline for you.
