When I walked into a home in Cherry Creek last winter, the homeowner pointed to their crumbling brick chimney and asked me a question I hear constantly: “Can this be fixed, or do we need to start over?” The chimney had been neglected for years, with mortar joints deteriorating and the crown badly cracked. But here’s what I’ve learned after years in this business—most chimneys don’t need complete rebuilds. What they need is thoughtful remodeling that addresses both function and appearance.
Chimney remodeling in Colorado isn’t just about aesthetics. Our climate demands it. Between freeze-thaw cycles that crack masonry, high-altitude UV exposure that ages materials faster, and our propensity for adding fireplaces to mountain homes, Colorado chimneys take a beating. I’ve seen beautiful homes with dangerous chimneys, and I’ve helped dozens of families transform failing systems into safe, efficient focal points.
Why Colorado Chimneys Need Special Attention
Our state presents unique challenges for chimney systems. The altitude alone changes how fires burn and how chimneys draft. Add temperature swings of 40-50 degrees in a single day, and you’re asking masonry to expand and contract constantly. Water seeps into tiny cracks during afternoon thunderstorms, then freezes overnight—even in summer at higher elevations.
I’ve inspected chimneys in Highlands Ranch, built just 15 years ago, that looked 40 years old due to weather exposure. The combination of intense sun, sudden hailstorms, and our dry climate, followed by heavy snow, creates a perfect recipe for deterioration. When homeowners call me about remodeling, they’re often addressing damage that has been accelerating for years without a proper chimney inspection.
When Remodeling Makes Sense
Not every chimney problem requires remodeling. Sometimes a simple chimney repair or standard maintenance solves the issue. But I recommend considering remodeling when:
Structural integrity is compromised. If the chimney is leaning, has large cracks running through multiple courses of brick, or shows signs of foundation settling, remodeling (or rebuilding) becomes necessary for safety.
The flue system is inadequate. Many older Colorado homes have chimneys built for wood-burning fireplaces that now house gas inserts or venting for furnaces. The existing flue may be oversized, undersized, or improperly configured. Remodeling allows us to install appropriate chimney liners and ensure proper venting.
Energy efficiency is suffering. Chimneys built before modern building codes were in effect often lack proper insulation or have gaps that allow heated air to escape. Remodeling provides us with the opportunity to seal these leaks and enhance the overall efficiency of our home.
You’re changing heating systems. Converting from wood to gas, adding a second appliance, or installing a gas insert often requires flue modifications that fall under the category of remodeling.
Aesthetic updates are desired alongside repairs. If you’re already addressing functional issues, it makes sense to update the appearance—whether that means re-facing with stone veneer, adding a custom chase cover, or modernizing the hearth area through fireplace repair and installation.
Common Remodeling Projects I Handle
Every remodeling job is unique, but specific projects consistently arise in the Denver metro area and mountain communities.
| Remodeling Service | Typical Cost Range | Timeline |
|---|---|---|
| Tuckpointing (single story) | $1,500 – $2,500 | 2-4 days |
| Crown Replacement | $400 – $800 | 1-2 days |
| Flue Liner Installation | $1,500 – $4,000 | 2-3 days |
| Chase Cover Replacement | $300 – $600 | 1 day |
| Stone Veneer Installation | $2,500 – $6,000 | 3-5 days |
| Complete Remodeling Package | $5,000 – $15,000+ | 1-2 weeks |
Tuckpointing and masonry restoration form the foundation of many remodeling jobs. When mortar joints deteriorate, water penetration accelerates. I carefully remove the damaged mortar and repoint with new material that matches the original. This process stabilizes the structure and prevents further damage. On a recent project in Washington Park, we tuckpointed a 1920s chimney that had been patched poorly years ago. The new mortar not only strengthened the chimney but also returned it to its original appearance.
Chimney crown repair and replacement address one of the most common failure points in chimneys. The crown—the concrete or mortar cap at the top of the chimney—protects the masonry from water. Colorado weather destroys crowns faster than almost anywhere else. I’ve replaced hundreds of badly cracked chimney crowns with properly built, code-compliant versions that include proper slope for drainage and overhangs to direct water away from the brickwork.
Flue liner installation or replacement often becomes necessary during remodeling. Clay tile liners crack from thermal stress or chimney fires. Many older chimneys lack liners entirely. I install stainless steel liners that meet current safety standards and work properly with modern heating appliances. These liners handle high temperatures, resist corrosion, and significantly improve draft performance.
Chase cover replacement is essential for factory-built fireplaces, which are standard in newer construction. The metal chase cover at the top of these chimneys corrodes quickly in Colorado weather. Rusted covers leak, staining walls and damaging the chimney structure. I replace them with stainless steel or copper chase covers that last decades instead of years.
Stone or brick veneer installation transforms the appearance of a chimney. A homeowner in Stapleton wanted their plain brick chimney to match their home’s modern aesthetic. We installed stacked stone veneer that complemented their exterior while maintaining the chimney’s structural integrity. The project took three days and dramatically improved their home’s curb appeal.
Waterproofing should accompany most remodeling projects. I apply breathable water repellents that keep moisture out while allowing water vapor to escape from within the masonry. This treatment extends the life of remodeling work and prevents freeze-thaw damage.
The Remodeling Process: What to Expect
When someone calls me at (720) 207-9232 about remodeling their chimney, we start with a thorough inspection. I need to understand what’s failing and why before recommending solutions. You can learn more about our services and what to expect during the process.
During the inspection, I examine the chimney from foundation to cap. I inspect for structural issues, assess the condition of mortar joints, analyze the flue liner, evaluate the crown and cap, and look for signs of water or fire damage. I use a camera to inspect the interior of the flue when necessary. Our chimney sweep services start at $150 for inspections that provide a clear picture of the work needed.
After inspection, I provide a detailed estimate that breaks down the remodeling work by component. You can check our pricing page for general cost guidelines. Prices vary widely based on scope. Tuckpointing may cost $1,500-$4,000, depending on the chimney’s size and access. Crown replacement typically costs between $40 and $800. Complete flue liner installation ranges from $1,500 to $4,000. Extensive remodeling projects, which often include multiple repairs, relining, and aesthetic updates, can cost $5,000-$15,000 or more for large chimneys.
The actual work timeline depends on the project scope. Simple jobs, such as crown replacement or chimney cap installation, typically take one to two days. Extensive tuckpointing and relining projects might require a week or more. Weather plays a huge role—we can’t apply specific mortars or sealants in freezing temperatures, and we avoid working in high winds or during storms.
A Story from Greenwood Village
Last spring, a family in Greenwood Village contacted me about their two-story chimney. They’d noticed interior water stains and pieces of brick in their yard after a hailstorm. Upon inspection, I found multiple issues: the crown had broken apart, the flashing was failing, numerous mortar joints required tuckpointing, and the clay flue liner had developed cracks throughout.
They’d gotten quotes ranging from “tear it down and rebuild” to “just patch the crown.” I explained that remodeling could save them money while making the chimney safe and functional for years to come. We developed a plan that addressed all the issues without complete demolition.
We started by carefully removing the damaged crown and several courses of brick at the top. We repointed every deteriorating joint on the exterior of the building. We installed a new stainless steel liner rated for their gas fireplace. We rebuilt the top courses with matching brick, added new flashing, and cast a properly designed crown with adequate overhang and a drip edge. Finally, we waterproofed the entire structure.
The project took six days and cost significantly less than rebuilding would have. The family now has a chimney that looks great and will serve them reliably for many years to come. They sent me photos last week—two Colorado winters later, and the chimney still looks perfect.
Colorado Code Requirements
Colorado has adopted the International Residential Code with state amendments, but local jurisdictions add their own requirements. Denver, Aurora, Colorado Springs, and mountain towns all have specific rules about chimney construction and remodeling. We serve all these areas and stay current on local codes—check our service areas to see if we cover your location.
Generally, any remodeling that affects the structural integrity or flue system requires permits. This includes relining, crown replacement involving masonry removal, and significant tuckpointing work. Simple repairs, such as replacing a chase cover or applying waterproofing, typically don’t require permits, but rules vary by location.
I always check local requirements before starting work. Permits might seem like a hassle, but they ensure the work meets safety standards and protects your investment. Inspectors have caught issues on my jobs that we corrected before they became problems. The permit process also provides documentation if you ever sell your home.
Working height matters too. OSHA regulations apply to chimney work, and many jurisdictions require specific fall protection measures for work above certain heights. This affects project cost and timeline, but keeps everyone safe.
Material Choices for Colorado Climate
Material selection significantly impacts how well remodeling holds up to our weather. I’ve tested various products over the years and learned what works in Colorado conditions.
| Material Category | Recommended Options | Why It Works in Colorado |
|---|---|---|
| Mortar | Type N or Type S with air entrainment | Flexibility handles thermal movement; air entrainment resists freeze-thaw damage |
| Flue Liners | 316L stainless steel | Superior corrosion resistance; handles temperature extremes and moisture |
| Crowns | Portland cement with plasticizers | Strong yet workable; proper drainage design prevents water pooling |
| Waterproofing | Vapor-permeable masonry sealers | Repels water while allowing interior moisture to escape; prevents spalling |
| Chimney Caps | Stainless steel or copper | Won’t rust in our weather; lifetime durability compared to galvanized steel. |
For mortar, I use Type N or Type S, depending on the application. These mortars provide good strength while remaining flexible enough to accommodate thermal movement. I match mortar color to existing work when possible, using pigments that resist UV fading.
For flue liners, stainless steel outperforms all other materials in Colorado. The alloy matters—316L stainless steel resists corrosion better than 304 in our climate. I size liners carefully based on the appliance and fuel type. Proper liner sizing affects draft, efficiency, and safety.
For crowns, I construct them using Portland cement-based mixes that incorporate plasticizers for enhanced workability and air entrainment for improved freeze resistance. The crown needs a proper slope (minimum of one-quarter inch per foot) and should overhang the chimney by at least two inches on all sides.
For waterproofing, I use vapor-permeable sealers specifically formulated for masonry. These products repel water while allowing moisture vapor to escape. Cheaper sealers trap moisture and cause spalling—I’ve repaired too many chimneys damaged by improper waterproofing.
For chimney caps, we offer several options, including adjustable safety caps and stainless steel caps, which provide lasting protection.
DIY vs. Professional Remodeling
Homeowners occasionally ask if they can tackle chimney remodeling themselves. Some aspects are manageable for experienced DIYers, but most remodeling work requires professional skills and equipment.
Tuckpointing may seem simple, but it requires proper technique, correct mortar mixing, and an understanding of joint profiles. Poor tuckpointing fails quickly and can damage masonry. The Crown building requires knowledge of concrete work and proper reinforcement. Liner installation must follow the manufacturer’s specifications and local codes—mistakes can create serious safety hazards.
The height factor alone makes most chimney work dangerous without proper equipment. I use scaffolding, fall protection, and safety gear that most homeowners don’t own. Working on roofs and at heights requires experience and training. We have specialized tools designed specifically for chimney work, ensuring both safety and high-quality results.
That said, homeowners can handle some maintenance that prevents the need for extensive remodeling. Applying waterproofing every few years, keeping the cap in good condition, and addressing minor mortar issues before they escalate are all within the DIY capabilities of people comfortable working at heights with proper safety measures. For detailed guidance, visit our chimney and fireplace blog, where I share maintenance tips and industry insights.
Cost Considerations and Value
Chimney remodeling costs vary significantly based on the scope, but I can provide realistic ranges for common projects in the Denver area.
| Project Scope | Cost Range | What’s Included |
|---|---|---|
| Minor Remodeling | $1,000 – $3,000 | Crown repair, cap replacement, minor tuckpointing,and waterproofing |
| Moderate Remodeling | $3,000 – $7,000 | Full tuckpointing, liner installation, crown rebuild, new cap, flashing repair |
| Major Remodeling | $7,000 – $15,000+ | Extensive masonry work, complete relining, stone veneer, multiple system updates |
Basic tuckpointing for a single-story chimney typically costs $1,500 to $2,500. Two-story chimneys can cost $2,500-$4,000 or more, depending on access and the extent of the damage. Crown replacement alone costs $400 to $800 for most residential chimneys. Flue liner installation ranges from $1,500 for simple straight runs to over $ 4,000 for complicated installations with multiple bends or long runs.
Complete remodeling projects that address multiple issues simultaneously may cost $5,000-$10,000 for typical chimneys or exceed $ 15,000 for large, complex jobs. While these numbers seem high, they’re significantly less than complete rebuilds, which often exceed $20,000.
The value returned varies. Necessary repairs and remodeling protect your home from water damage, improve safety, and maintain structural integrity. These projects prevent much more expensive problems down the road. Aesthetic improvements add curb appeal and can increase home value, although probably not dollar-for-dollar in relation to the remodeling cost.
Seasonal Timing in Colorado
Timing matters for chimney remodeling in Colorado. I stay busy year-round, but certain seasons are more suitable for specific projects.
Spring and fall offer ideal conditions for most remodeling work. Temperatures are moderate, precipitation is relatively light, and we can work without extreme heat or cold affecting materials. These seasons book up fast, so planning helps secure your preferred schedule.
Summer works well, but brings challenges. Afternoon thunderstorms can interrupt work, and extreme heat affects mortar curing times. We start early and work around the weather. Mountain properties become accessible, so summer is often the only option for high-elevation homes.
Winter remodeling is possible but limited. We can handle certain repairs on mild days, but many materials require temperatures above freezing for proper curing. Emergency repairs happen regardless of weather, but planned remodeling often waits until spring.
I recommend scheduling inspections for late summer or fall. This gives us time to plan remodeling projects for the following spring before the chimney faces another harsh winter. Early planning also helps homeowners budget for necessary work.
Maintenance After Remodeling
Proper maintenance protects your remodeling investment and extends its life. I provide specific maintenance instructions based on the work performed, but general guidelines apply to all remodeled chimneys.
Schedule annual inspections even after remodeling. These checkups catch minor issues before they become significant problems. I offer yearly inspection packages that include cleaning and minor maintenance for a flat Fee.
Keep the chimney cap in good condition. The cap prevents animals from entering and shields the crown from direct weather exposure. Replace damaged caps promptly—we stock a variety of Master Flow caps and custom multi-flue caps for quick replacement.
Clean the chimney regularly, depending on its use. Wood-burning fireplaces need annual cleaning with proper chimney sweep services. Gas appliances require less frequent service, but they still need periodic inspections to ensure appropriate venting. We also offer dryer vent services, as these systems are often overlooked during home maintenance.
Monitor for water stains or efflorescence (white mineral deposits) on the eexteriorof the cchimney These signs indicate water penetration that needs immediate attention.
Trim tree branches away from the chimney. Falling branches damage crowns and caps, and overhanging vegetation holds moisture against masonry. Speaking of wildlife, we also handle animal removal from roofs and chimneys—squirrels and raccoons often nest in chimneys, causing significant damage.
Reapply waterproofing every 3-5 years, depending on weathethe level of r exposure. This simple maintenance step prevents extensive damage and extends the life of tuckpointing and masonry work.
Finding the Right Professional
Choosing someone to remodel your chimney matters enormously. This isn’t work you want to hire out based solely on price. Learn more about our company and our approach to chimney services.
Look for contractors with specific experience in chimney work, not just general masonry work. Chimneys have unique requirements that general masons may not understand. Ask about certifications—many chimney professionals hold certifications from the Chimney Safety Institute of America (CSIA) or the National Fireplace Institute (NFI).
Request detailed written estimates that break down the work by component. Vague estimates often lead to disputes and change orders. Good contractors explain what they’re doing and why.
Check references and review past work if possible. Ask specifically about how the work held up over time, whether the contractor communicated well, and if the final cost matched the estimate.
Verify insurance and licensing. Chimney work is a hazardous activity, and you need to have protection in place in case someone gets hurt on your property. Colorado requires contractors to be registered with the state, and many municipalities have additional licensing requirements.
Be skeptical of extremely low bids. Quality materials and skilled labor cost money. Rock-bottom prices usually indicate shortcuts, inexperience, or incomplete work scope. I’ve remodeled too many chimneys that were “fixed” cheaply just months before.
