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.

AfterTrusted Chimney Repair for Boulder Homeowners
Chimney repair in Boulder typically costs between $350 for minor mortar repointing and $8,500 for a full chimney rebuild, with most homeowners spending $1,200-$3,800 on common repairs like flashing replacement or spalling brick restoration. Emberly Chimney Cleaners Boulder has completed more than 38,000 chimney inspections and cleanings since 2009, and every repair job starts with a written price, a camera-scan inspection, and a documented photo record before any work begins. Call us at (970) 598-0453 for a free estimate with upfront pricing.
Boulder’s combination of freeze-thaw cycles, intense UV exposure at 5,400 feet, and sudden summer thunderstorms creates unique stress on masonry chimneys. We’ve found that homes in Mapleton Hill and the Chautauqua area, many built between 1900 and 1940, show accelerated mortar deterioration compared to newer construction in Gunbarrel or Martin Acres. Our technicians carry DuraFlex liner materials, HeatShield refractory mortar, and Gelco stainless caps on every truck, so most repairs don’t require a return visit. Corrine Halstead established the Haven Standard in 2009 to eliminate the guesswork and price shock that still plague this trade, and that standard governs every Chimney Repair - Boulder job we perform in Boulder County.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar repointing is the process of grinding out deteriorated mortar between bricks and packing fresh, matched mortar into the joints. In Boulder, we see accelerated mortar failure in homes within two miles of the foothills, where wind-driven snow and rapid temperature swings force moisture deep into the masonry. Our crews use Type N or Type S mortar matched to your chimney’s original composition, and we document the joint depth and coverage with photos before and after, as required by Haven Standard Clause 4.
Spalling Brick Repair
Spalling occurs when water trapped inside bricks freezes, expands, and flakes off the face of the brick, leaving the softer interior exposed to further damage. Boulder’s 30-degree daily temperature swings in spring and fall make this especially common in north-facing chimneys that never fully dry. We remove spalled bricks to solid substrate, source matching replacement brick through our Copperfield supply network, and rebuild the affected courses with proper weep holes and drainage.
Chimney Waterproofing
Chimney waterproofing applies a vapor-permeable silane/siloxane sealant that blocks liquid water while allowing trapped moisture to escape. We apply this treatment after any masonry repair and recommend it for every Boulder chimney over 15 years old, particularly in neighborhoods like Newlands and Whittier where mature trees shade chimneys and slow evaporation. Our waterproofing carries a 10-year performance warranty and includes a written moisture-meter reading taken before application.
Flashing Repair
Flashing is the sheet metal (typically galvanized steel, copper, or aluminum) that bridges the gap between your chimney and roof, and it’s the single most common source of chimney leaks we find in Boulder. The combination of heavy spring snow loads and intense summer sun causes flashing to fatigue, separate, or corrode at the corners. We fabricate custom flashing on-site when possible, use only lead-free solder for copper work, and test every repair with a water hose flood test before we leave.
Chimney Rebuilding
Chimney rebuilding becomes necessary when structural integrity is compromised by widespread spalling, settled foundations, or earthquake damage, which we assess with a Level 2 camera inspection and structural evaluation. In Boulder, we’ve rebuilt chimneys in the University Hill area damaged by the 2011 Virginia Dale earthquake swarm and in Table Mesa homes where expansive soils caused the chimney to separate from the house. Every rebuild includes a written structural warranty, new stainless steel liner sizing, and a final NFPA 211 compliance report.
Tuckpointing
Tuckpointing is a specialized form of repointing where two contrasting mortar colors are used to create the illusion of fine, uniform joints, historically common in Boulder’s Victorian and Craftsman homes. We match both the flush mortar and the narrow “tuck” line to your home’s original aesthetic, using natural pigment rather than synthetic dyes that fade in Boulder’s UV intensity. This is skilled, slow work, and we price it by the linear foot with no surprises.

Brands We Service for Chimney Repair
We’ve installed and repaired DuraFlex stainless steel chimney liners in more than 4,000 Boulder-area homes since 2009, and we stock their full range of diameters and flex lengths for same-visit liner replacement when inspection reveals deterioration. HeatShield’s cerfractory foam resurfacing system is our standard repair for smoke chamber parging in older Boulder fireplaces, and we’ve been certified installers since 2012. Gelco’s stainless steel chimney caps and chase covers are our default recommendation for Boulder’s hail-prone climate, and we keep their most common sizes in our Louisville warehouse.
Whether your chimney was built with Olympia Chimney’s clay flue tiles, Famco’s venting components, or any other make, we can source compatible repair materials through Haven’s buying network and document the match in your written scope. Our policy is simple: no repair starts until you’ve seen the photos, read the price, and approved the work in writing.
BeforeAfterSigns You Need Chimney Repair Right Now
- White staining (efflorescence) on your chimney exterior means soluble salts are being drawn through the mortar by moisture migration, which indicates water is getting in and minerals are getting out. Left alone, this process dissolves the mortar from the inside, and we’ve repointed chimneys in North Boulder where efflorescence was visible for three years before the owner called.
- Loose or missing bricks, or bricks that sound hollow when tapped signal that the freeze-thaw cycle has already compromised the brick structure. In Boulder’s climate, a single loose brick in October often becomes a dozen by April, and the repair cost multiplies with each freeze cycle.
- Rust stains on your chimney crown or down the face of the brick indicate that your metal flue liner or damper is corroding from the inside, usually due to a leak at the crown or flashing. The rust accelerates the deterioration of both the liner and the surrounding masonry.
- Damp or stained drywall on interior walls adjacent to the chimney means water is already inside your home’s envelope, and the leak has progressed past the point where simple flashing repair will solve it. We’ve opened walls in South Boulder homes where the framing behind the drywall was 40% deteriorated before the stain became visible.
- Your chimney leans, even slightly, or has separated from the house wall indicates foundation settlement, structural failure, or earthquake damage that requires immediate evaluation. Do not use the fireplace. A leaning chimney can collapse without warning, and Boulder County’s expansive soils and seismic activity make this a genuine hazard we assess at every inspection.
Our Chimney Repair Process - Step by Step
- 1
Schedule and confirm. Call (970) 598-0453 and you’ll reach a live person, 24 hours a day. We book a two-hour arrival window, assign a named technician, and text you when they’re en route. No voicemail, no web form black hole.
- 2
NFPA 211 Level 2 inspection with camera documentation. Your technician runs a high-resolution camera the full length of the flue, photographs the crown, flashing, and exterior masonry, and records moisture-meter readings where indicated. You see the footage in real time. This is Haven Standard Clause 4, and we’ve done it on every job since 2009.
- 3
Written diagnosis and price. Before any repair work begins, you receive a written scope with line-item pricing, material specifications (including brand names), and a completion date. Clause 1 of the Haven Standard requires this in writing, and we don’t deviate. If you have a competitor’s written estimate, we’ll provide a free second opinion.
- 4
Repair with photo documentation. Your technician performs the agreed work, photographing each stage for your record. For masonry repairs, we document joint depth, mortar mix, and curing protection. For flashing work, we photo the water test.
- 5
Final inspection, written warranty, and archive. We conduct a post-repair camera scan where applicable, provide your written warranty under the 365-Day Done Right Promise, and archive all photos and documentation to your customer record. If it’s not done right, we make it right.
How Much Does Chimney Repair Cost in Boulder?
| Repair Type | Typical Range in Boulder | What Drives the Price |
|---|---|---|
| Mortar repointing (partial) | $350 - $1,200 | Height, accessibility, mortar type match |
| Spalling brick replacement (per area) | $800 - $2,400 | Brick match difficulty, structural rebuilding needed |
| Chimney waterproofing | $450 - $950 | Surface area, prep cleaning required |
| Flashing repair/replacement | $650 - $1,800 | Roof pitch, metal type, chimney size |
| Chimney rebuilding (partial) | $3,500 - $6,500 | Height, liner replacement, scaffolding |
| Full chimney rebuild | $6,500 - $8,500+ | Foundation work, historic preservation requirements |
| Tuckpointing (decorative) | $12 - $25 per linear foot | Joint width, color matching complexity |
These ranges reflect what we’ve charged Boulder homeowners over the past three years, and they’re current as of our last pricing review. The biggest variable is always what we find after the camera goes down: a chimney that needs repointing from the roofline up costs less than one where deterioration extends below the roof deck. We don’t speculate. We inspect, photograph, and price.
How to avoid overpaying: get the scope in writing before work starts, verify that the price includes materials from recognized brands like DuraFlex or HeatShield rather than generic substitutes, and ask whether the quoted price includes the NFPA 211 inspection and photo documentation or treats them as add-ons. At Emberly Chimney Cleaners Boulder, they’re included on every job. Call (970) 598-0453 for your exact quote - estimates are free, and we don’t charge to look.

Frequently Asked Questions - Chimney Repair in Boulder
Chimney repair fixes structural or functional damage to your chimney’s masonry, metal components, or waterproofing, while a chimney sweep removes combustible creosote deposits from the flue. We perform both services, but we never recommend repair work without first conducting the NFPA 211 Level 2 inspection that reveals whether the problem is cosmetic, functional, or safety-critical. Call (970) 598-0453 to schedule either service.
Most single-element repairs, such as flashing replacement or partial repointing, are completed in one day. Extensive masonry rebuilding or tuckpointing on historic chimneys may require two to three days with curing time between stages. We specify the timeline in your written scope before work begins, and we don’t charge additional labor if weather delays extend the schedule.
Typical chimney repair in Boulder ranges from $350 for minor mortar repointing to $8,500 or more for a full rebuild, with most homeowners paying between $1,200 and $3,800 - here’s how much Chimney Repair costs in more detail. The exact price depends on what our camera inspection reveals about the extent of damage, the materials required, and access difficulty. We provide a written, line-item estimate before any work starts, and our estimates are always free. Call (970) 598-0453 for your specific quote.
Yes. We’ve installed and repaired HeatShield smoke chamber resurfacing systems, DuraFlex stainless steel liners, and Gelco chimney caps and chase covers in thousands of Boulder-area homes. We source these materials through Haven’s buying network to keep pricing honest, and we document the brand and model in your written scope. If your chimney uses another manufacturer’s components, we can typically source compatible repair materials.
Our live phone support operates 24 hours a day, 7 days a week, and we maintain emergency capacity for active leaks, storm damage, and structural hazards that make a chimney unsafe to use. We don’t charge premium rates for after-hours calls, though scheduling priority goes to safety-critical situations. If your chimney is leaning, has suffered impact damage, or is actively leaking into your home, call (970) 598-0453 immediately.
Every chimney repair is backed by our 365-Day Done Right Promise: if it’s not done right, we make it right, with no cost to you for our return. Masonry waterproofing carries a 10-year performance warranty against water penetration. Flashing repair is warranted for 5 years against leakage. Specific warranty terms are written into your scope before work begins, as required by Haven Standard Clause 1.
Clear a path from your driveway to the chimney area, remove vehicles from the garage if scaffolding will extend over it, and cover furniture near the fireplace if interior work is planned. We bring our own drop cloths, HEPA vacuums, and debris containment, but we appreciate access to an outdoor hose for water testing. Your technician will confirm specific preparation needs when they call to confirm your appointment.
