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.

Why Level Two Chimney Fairfax Is Chantilly’s Preferred Chimney Repair Company
Chantilly’s housing stock is not like the older brick neighborhoods you find in Fairfax or Reston. The majority of homes here were built between 1982 and 2005, and almost all of them use factory-built, zero-clearance fireplaces inside wood-framed, vinyl-sided chases rather than true masonry chimneys. That changes how a repair gets done, and it changes what a sweep needs to know. Our team has inspected and cleaned more than 38,000 chimneys since 2009, and the Chantilly jobs we see week after week are prefab chases, Class-A metal flues, and refractory panels, not brick-and-mortar stacks. We know where local builders cut corners, which subdivision layouts trap moisture, and what a failing chase cover off Route 50 looks like before it becomes a $3,000 rebuild.
Corrine Halstead, who leads Level Two Chimney Fairfax, insists on one thing above all: a written price before work starts. No tech climbs a ladder in Chantilly without a documented scope and a written warranty ready for you. That’s Haven Standard Clause 1, and it’s been the rule since 2009. We also answer the phone with a live person 24/7, not a voicemail and not a web form. When you call about a chimney issue in Chantilly Highlands or Westfield, you’ll talk to someone who can actually schedule the visit, not someone who promises to pass along a message.
Our Chimney Repair Services in Chantilly
Chantilly is a Chantilly market where chimney repair usually means working on prefab systems, flashings, and chase enclosures. Here’s what we handle most often for homeowners in this area, and what each service actually involves when we find the problem in a Chantilly home.
Mortar Repointing
True masonry chimneys are rarer in Chantilly than in older communities, but they exist, mostly in the pre-1980s pockets and a few custom builds along Bull Run Post Office Road. When the mortar joints between bricks start to erode, rainwater gets behind the brick and freezes, pushing the structure apart. Repointing in Chantilly runs $12 to $25 per square foot for average joint depth. We cut out the old mortar to the right depth, pack in new mortar matched to your existing color, and document the repair with photos before and after. If the damage goes deeper than the mortar, we’ll tell you that in the written scope, not after the job starts.
Spalling Brick Repair
Spalling is what happens when brick faces flake off or pop loose, usually because moisture inside the brick freezes and expands. In Chantilly, where freeze-thaw cycles hit hard from November through March, spalling shows up on the exterior brick veneers of chimneys that face the worst of the wind. Repairing spalled brick in Chantilly typically runs $300 to $900 per affected area depending on how many units need replacement and whether the crown is involved. We’ll replace the damaged bricks, check what let the water in to begin with, and fix that too. A brick repair that ignores the water source is a repeat visit waiting to happen.
Chimney Waterproofing
This is one of the most cost-effective services in Chantilly, and it’s the one we recommend to most homeowners after any exterior chimney work. Waterproofing a chimney with a breathable siloxane-based sealant costs $250 to $600 depending on chimney size and access. The sealant keeps liquid water out while letting the masonry breathe, so moisture doesn’t get trapped inside the brick. Given how aggressively the freeze-thaw cycle attacks Chantilly’s wood-framed chases and brick veneers, waterproofing after a repointing or flashing repair extends the life of the work by years. We apply it with a low-pressure sprayer and document the coverage area. It’s not a substitute for fixing a leak, but it prevents the next one.
Flashing Repair
Flashing is the metal strip system where the chimney meets the roof, and it fails in Chantilly more often than people expect. A typical flashing repair in Chantilly runs $350 to $800, depending on the roofline complexity and whether we’re replacing one section or the full system. The reason it fails so often locally comes down to construction. Many of our Chantilly jobs involve caulked seams on vinyl-sided chase enclosures that fail after repeated freeze-thaw cycles, letting water seep behind the siding and into the framing. We replace the flashing, seal the joints properly, and check the chase interior with a camera to see if moisture already got in. If your chimney cap looks fine but you’re still getting water, the flashing is usually the culprit.

BeforeAfterTrusted Brands We Service in Chantilly
Because Chantilly’s fireplaces are overwhelmingly factory-built, parts availability matters. We stock and source components from Olympia Chimney, DuraFlex, and Famco specifically because those manufacturers produce the Class-A metal flue systems, chase covers, and termination caps used in Chantilly’s 1980s and 1990s subdivisions. When a prefab flue section rusts through in a Chantilly Highlands chase, we don’t want you waiting two weeks for a back-ordered part from a distributor who doesn’t know this market. Having the right components on hand means faster turnaround on repair approvals and fewer return visits. And every repair using these materials is covered by our written warranty and the 365-Day Done Right Promise.
Common Chimney Repair Problems We See in Chantilly Homes
Here’s what our Chimney Repair team sees most often when we work in Chantilly specifically.
- Moisture intrusion through failing chase covers. Most Chantilly chases are wood-framed boxes covered in vinyl siding with a metal cap on top. When that cap rusts or the caulk fails, water gets inside and rots the framing while rusting the metal flue above the roofline. We find this in nearly every Chantilly home where the fireplace hasn’t been inspected in five or more years.
- Cracked refractory panels in zero-clearance fireboxes. Homeowners assume a newer chimney needs no inspection. But refractory panels in factory-built fireplaces made in the 1980s and 1990s are now at or past their rated service life. A crack lets heat reach the firebox walls, and that’s a fire hazard.
- Caulked seam failures on vinyl-sided chase enclosures. Northern Virginia’s freeze-thaw cycles are brutal on caulked seams. When caulk loses its bond, water seeps behind the siding and into the chase framing. You won’t always see it from the ground, which is why our camera inspection goes into the chase, not just up the flue.
- Accelerated creosote buildup from wind-driven drafting. Cold northwest winds funneled down from the Bull Run Mountains create strong updraft conditions in Chantilly, pulling unburned creosote higher into flue liners before it condenses. That accelerates Stage 2 and Stage 3 creosote buildup, especially in homes where the fireplace is used only occasionally. Dense creosote in a prefab metal flue is a chimney fire risk, and it needs to be removed by a professional.
Pricing for Chimney Repair in Chantilly, VA
Here are the ranges we typically quote in Chantilly, written plainly so you can budget before you pick up the phone.
- Mortar repointing: $12-$25 per square foot
- Spalling brick repair: $300-$900 per affected area
- Chimney waterproofing: $250-$600
- Flashing repair: $350-$800
- Chase cover replacement: $400-$1,200 depending on size and material
- Full chase rebuild (framing and siding): $1,500-$3,500 when rot is extensive
What moves your price within these ranges comes down to access, material condition, and how far the failure has progressed. A simple flashing replacement on a one-story colonial in Westfield is very different from a chase rebuild on a three-story transitional near Route 50 where the framing has been absorbing water for a decade. That’s why we don’t quote over the phone. We inspect first, show you the camera footage, tell you what can wait and what can’t, and hand you a written price. That’s the whole point of Level Two’s approach. For an exact quote on your Chantilly home, call (571) 443-8256. Estimates are free, and we’ll bring a second opinion on any competitor’s written estimate if you have one.

FAQs - Chimney Repair in Chantilly
Yes. A factory-built fireplace in Chantilly needs the same annual inspection as a masonry chimney, because the failure modes are different but just as real: rusted metal flues, cracked refractory panels, and rotted chase framing. Homeowners often skip inspection on newer-looking chases because nothing looks old from the outside, but by the time you see rust or a water stain, the repair bill has usually doubled. Call (571) 443-8256 and we’ll put a camera down the flue and give you a written report.
The most common chimney repair issue in Chantilly’s Westfield or Chantilly Highlands neighborhoods is moisture intrusion through a failing chase cover on a wood-framed, vinyl-sided chase. Those chases are 25 to 40 years old now, and the metal caps rust through or the caulked seams fail, letting water rot the framing and rust the Class-A metal flue. We’ve seen hidden rot that only becomes visible when the chase cap is removed during a cleaning. For a camera-scan inspection that shows you exactly what’s happening inside your chase, call (571) 443-8256.
A wood-framed chase with hidden rot usually pushes a Chantilly chimney repair from a $500 flashing job into a $1,500 to $3,500 chase rebuild, because the rotten framing has to be replaced before the siding and cap can be reinstalled. That’s why we inspect the chase interior with a camera on every visit, not just the flue. When we found a Chantilly Highlands home where moisture had been trapped behind vinyl siding for years, the metal flue from Olympia Chimney had rusted through at the termination and the repair required replacing framing, flashing, and the damaged flue section. The sooner the moisture is caught, the smaller the bill. Call (571) 443-8256 for a written inspection report.
Yes, third-degree creosote can be removed from a prefab metal flue, but it requires chemical treatment and special rotary tools designed for Class-A metal systems, not the wire brushes used on masonry flue tile. Chantilly’s wind-driven drafts accelerate creosote buildup in infrequently used fireplaces, and dense creosote is the fuel for a chimney fire. This is a job for a trained professional with the right equipment, and it’s always followed by a camera inspection to confirm the liner is safe. Call (571) 443-8256 and we’ll document what we find before and after the cleaning.
Chantilly chimney repairs often involve flashing even when the chimney cap looks fine because water enters at the roofline seam, where the flashing meets the roof deck, not at the cap. Caulked seams fail after repeated freeze-thaw cycles, and the water travels behind the siding and into the chase framing before you ever see it inside the house. The cap can be perfectly intact while the flashing fails below it. That’s why our written inspection covers the roofline, not just the visible chimney. For a free estimate, call (571) 443-8256.
