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.

Call (571) 946-2300 for a written estimate before anyone starts work.
Why Level Two Chimney Manassas Is Great Falls’s Preferred Chimney Repair Company
Great Falls isn’t like McLean or Reston when it comes to chimneys. The lots are bigger, the tree canopy is denser, and the houses routinely have three, four, even six fireplaces. Our repair crews have walked more Great Falls rooftops than we can count, and we understand what the Potomac River gorge does to masonry over a decade. The humidity that settles into the river corridor accelerates mortar deterioration, and the mature oaks and tulip poplars that shade these properties drop debris that clogs caps and holds moisture against crowns. That’s not a generic chimney problem; that’s a Great Falls chimney problem, and we’ve been diagnosing it here long enough to know the difference.
Every Great Falls job includes a camera-scan inspection, a written price before work starts, and a documented photo record when we’re done. That’s Clause 4 of the Haven Standard, and it’s been our practice since 2009. If a repair isn’t done right, our 365-Day Done Right Promise means we make it right. That’s the whole point of putting it in writing.
We answer the phone with a live person, 24/7. We text you when the tech is on the way, and the tech’s license number is on the page before they arrive. No call-center runaround, no “call for a quote” nonsense. A written price, written scope, written warranty. That’s Clause 1 of the Haven Standard: have it in writing.
Our Chimney Repair Services in Great Falls
Great Falls chimneys take more abuse than most. When we arrive for a repair call, we’re usually looking at a multi-flue masonry chimney that hasn’t been touched since the 1980s. Here’s what we handle most often.
Mortar Repointing
Great Falls’s older brick chimneys lose mortar joints over time, especially on the upper sections exposed to gorge humidity and freeze-thaw cycles. We rake out deteriorated mortar and repoint with a color-matched mix that blends with the original brick. On a typical Great Falls Colonial, repointing runs $400-$1,800 depending on how much of the stack is involved.
Spalling Brick Repair
Spalling is when the brick face flakes or pops off, usually because water got in and froze. On Mill Run Drive, we repaired a 1980s brick Colonial where two of four flues had spalling clay tile liners and a cracked crown from raccoon damage. We installed a DuraFlex stainless steel liner in the primary flue, repointed the smoke chamber, and fitted a Copperfield chimney cap with wildlife screening, then completed a Level 2 inspection to confirm draft on all remaining flues. That’s a standard Great Falls repair, not an unusual one. Spalling repair here typically runs $500-$2,500.
Chimney Waterproofing
Water is the root cause of most chimney damage, and Great Falls gets more of it than nearby cities because of the river gorge microclimate. We apply a vapor-permeable waterproofing treatment to the masonry so water stays out but the brick can still breathe. Trapping moisture inside the chimney is worse than letting it in. Waterproofing a typical Great Falls chimney costs $350-$900.
Flashing Repair
Flashing is the metal where the chimney meets the roofline, and on Great Falls estate homes with steep rooflines and custom dormers, it takes a beating. Failed flashing shows up as water stains on the ceiling near the fireplace or damp drywall in the attic. We replace flashing with proper step and counter-flashing rather than just caulking over the old stuff, which never holds. Flashing repair around Great Falls runs $500-$1,400.
We also handle Chimney Repair work that goes beyond the masonry itself: crown rebuilds, smoke chamber parging, and liner resurfacing with HeatShield, which can buy a cracked clay liner another 15-20 years without a full teardown.

BeforeAfterTrusted Brands We Service in Great Falls
When a Great Falls chimney needs a new liner or cap, we use materials from DuraFlex, Copperfield, and HeatShield, sourced through the Haven buying network to keep pricing honest. Our repair crews keep a working inventory of these materials on the truck because Great Falls chimneys rarely need just one thing. A cracked liner and a failed cap usually go together. If you need a stainless steel liner in a 1980s Colonial with four flues, we can usually have parts on-site within days, not weeks.
Common Chimney Repair Problems We See in Great Falls Homes
- Original clay tile liners failing after 30-50 years. Homes built in the 1970s through the 1990s often still have their original clay liner, and repeated heavy burning seasons crack those tiles. Once a liner cracks, creosote and moisture reach the framing, which is a fire hazard.
- Tree-canopy debris clogging caps and trapping moisture. The dense oak and tulip poplar canopy over Great Falls lots drops limbs, leaves, and acorns onto chimney crowns constantly. Clogged caps trap moisture against the masonry, which accelerates spalling.
- Multi-flue chimneys hiding problems in unused flues. A house with four fireplaces and only one in regular use still has three flues that need inspection. We routinely find Class III creosote (the hard, glazed kind) in flues that haven’t been used in years.
- Raccoon and chimney swift nesting causing interior damage. The mature trees around Great Falls are ideal chimney wildlife habitat. Nesting animals bring in sticks and droppings, scratch up clay liners, and sometimes die in the flue. A screened cap ends the problem reliably.
Pricing for Chimney Repair in Great Falls, VA
Great Falls pricing differs from McLean or Reston because the chimneys are larger, there are more flues per house, and the tree canopy means caps and flashing need more frequent attention. Here are the numbers we quote most often:
| Repair Type | Typical Range in Great Falls |
|---|---|
| Mortar repointing | $400 - $1,800 |
| Spalling brick repair | $500 - $2,500 |
| Chimney waterproofing | $350 - $900 |

| Chimney rebuilding (full or partial) | $2,500 - $6,500 |
| Stainless steel liner installation | $2,200 - $4,800 |
| Tuckpointing | $15 - $30 per square foot |
The final number depends on how many flues are involved, how much of the stack is deteriorated, and whether we’re working from a ladder or a lift. Every quote is written, itemized, and delivered before any work starts. Call (571) 946-2300 and we’ll schedule a camera inspection so you can see exactly what we’re recommending.

FAQs - Chimney Repair in Great Falls
Great Falls homes typically have three to six fireplaces, which means three to six flues to inspect, each requiring its own camera scan. A single inspection in McLean might cover one or two flues in an hour; a Great Falls inspection commonly takes two to three hours to document every flue properly. That’s why inspection pricing runs higher here: it’s more flues, more footage, and more time. Call (571) 946-2300 for an exact quote before we come out.
The gorge corridor holds moisture that accelerates mortar joint deterioration and spalling on Great Falls chimneys, especially on the sides that face the river or sit under dense tree shade. Masonry that would last 20 years in drier areas often shows real damage in 10 to 12 years here. That’s why we recommend a waterproofing treatment on every Great Falls chimney repair, and why we push camera inspections hard: many Great Falls chimneys look fine from the ground but are failing at the crown. Call (571) 946-2300 and we’ll show you the footage.
Yes, in most cases. We can repoint mortar joints, replace spalled bricks individually, and parge the smoke chamber without touching the rest of the stack. The original brick on 1970s Great Falls Colonials is usually worth keeping, and we go to some length to preserve it. When the damage is too extensive, we’ll show you photos and explain exactly what needs to come out and why. Get a camera inspection before anyone starts swinging a hammer: call (571) 946-2300.
A stainless steel chimney cap with wildlife screening, sized to the flue and installed properly, stops raccoons, squirrels, chimney swifts, and most debris. We use Copperfield caps with heavy-gauge screening because the raccoons in Great Falls are persistent and the standard hardware-store caps don’t hold up. We’ll also do a camera inspection to check for existing nests or debris before the cap goes on. Call (571) 946-2300 to schedule a cap installation; we can usually get a crew to Great Falls within the week.
Yes. The gas flue still needs checking for blockages and liner condition, and the wood-burning flues need inspection for creosote accumulation, even if they haven’t been used in years. We find third-degree creosote in unused Great Falls flues more often than in active ones, because nobody was looking. The NFPA 211 standard covers every flue, regardless of fuel type or use. Book a multi-flue inspection by calling (571) 946-2300; the price is written before we arrive.
