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.

We’ve been dispatching crews to Dunn Loring from our Washington, DC office for decades, and the phone calls we get here follow a pattern. Homeowners along Gallows Road and Prosperity Avenue notice a smoky smell on the first cold morning. Someone in a brick colonial off Cedar Lane spots crumbling mortar after another freeze-thaw winter. A seller near the Dunn Loring-Merrifield Metro station needs a camera inspection report before closing. These chimneys are old, the housing stock turns over fast, and the weather here is hard on masonry. We know what to look for because we’ve looked at hundreds of them.

Why Dunn Loring Homeowners Choose Hearthstone Chimney Co.
Russell Haines founded this company in 1984, and we’ve spent the last 42 years building a reputation one chimney at a time. Dunn Loring homeowners aren’t looking for the cheapest bid - they’ve been through enough contractor headaches to know that a low estimate often hides a bigger invoice later. They want someone who shows up when promised, explains what they found, and puts the guarantee in writing.
Our 90-Day Done Right Promise works exactly that way. If something isn’t right, we come back and make it right. No paperwork to dig up, no argument about whether the problem existed before. It’s governed by our K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it. That promise has been in force since long before most Dunn Loring chimneys were due for their first relining.
We serve homes throughout the Dunn Loring Heights and Williamsburg Village neighborhoods regularly, along with the ranchers and split-levels near Merrilee Drive and the older colonials closer to Marshall Road. Our technicians are background-checked, uniformed, and trained to complete most jobs in a single visit. The price we quote upfront is the price on the invoice.
A live person answers our phones 24 hours a day, 7 days a week. Not a callback queue, not an app, not “press 3 for scheduling.” Someone who can actually book your appointment or answer a question about what that smell might mean.

Why Dunn Loring’s Climate & Housing Affect Chimney Cleaning
Dunn Loring sits in a peculiar spot, climate-wise. We’re not cold enough for sustained deep freeze, but we get dozens of freeze-thaw cycles each winter - temperatures swing above and below 32 degrees repeatedly from December through March. Water seeps into hairline cracks in mortar joints and terra cotta flue liners, expands when it freezes, and widens those cracks incrementally. By spring, a chimney that looked sound in October may have spalling brick faces, deteriorated crown concrete, and liner segments that have shifted or cracked.
This matters for cleaning because creosote and debris hide in those cracks, and because a damaged liner changes how we approach the job. In a sound chimney, a standard sweep clears the flue. In many Dunn Loring chimneys - especially the 50-70 year old originals in neighborhoods like Dunn Loring Heights - we find liner damage that makes a basic sweep insufficient and potentially unsafe. The flue may be oversized for the gas appliance now venting through it, or the separation between fireplace and utility flues may have compromised, creating a carbon monoxide pathway.
We’ve also learned to check for a specific Dunn Loring problem: chimneys originally built for oil-fired furnaces that were never properly relined when homeowners converted to gas. Fairfax County code now requires proper liner sizing for gas appliances, and this deficiency surfaces constantly in home inspections around the Dunn Loring-Merrifield Metro station, where real estate turnover runs higher than you’d expect for such a small community. When we sweep a chimney here, we’re also assessing whether the system as configured meets current safety standards - not just whether it’s clean.
Pricing for Chimney Cleaning in Dunn Loring
We don’t quote over the phone without asking some questions, because a 1962 rancher with a sealed fireplace and a 1974 colonial with a wood-burning insert and double flue are different jobs. But Dunn Loring homeowners deserve honest numbers to plan around. Here’s what our appointments typically run:
| Service | Typical Range |
|---|---|
| Standard chimney sweep with Level-1 inspection | $189 - $349 |
| Level-2 camera inspection (real estate, suspected damage) | $425 - $595 |
| Chimney cap installation (standard stainless) | $285 - $495 |
| Crown repair or rebuild | $485 - $1,250 |
| Fireplace smoke chamber parging | $650 - $1,100 |
| Stainless steel liner installation (single flue) | $2,800 - $4,500 |
We offer a $89 Seasonal Tune-Up for standard fireplaces during our shoulder-season booking windows. Seniors and veterans receive a standing 5% discount on all services. If you’ve received a written estimate from another company for repair work over $250, we’ll beat it by $50 and provide a free second opinion with photos you can compare.
The estimate we give before booking is the number on the invoice. No surprises, no “we found something else” add-ons without discussion.

FAQs About Chimney Cleaning in Dunn Loring
A standard sweep with Level-1 inspection typically costs between $189 and $349, depending on flue condition, accessibility, and whether the system has been maintained regularly or neglected for years. Level-2 camera inspections, which we recommend for any Dunn Loring home sale or when liner damage is suspected, start around $425. Call (571) 489-4365 for an exact quote - estimates are free.
The National Fire Protection Association recommends annual inspection for all chimney systems, with cleaning frequency determined by use and fuel type. Wood-burning fireplaces used regularly during Northern Virginia’s heating season should be swept annually. Gas appliances vented through masonry chimneys need yearly inspection for liner integrity, especially in Dunn Loring’s older housing stock where original flues were often not properly resized for gas conversion. Call (571) 489-4365 to schedule - we’ll tell you honestly whether your system can wait or needs immediate attention.
We won’t recommend a liner replacement without camera evidence you can see for yourself. In Dunn Loring’s 1950s-1970s homes, we frequently find terra cotta liners that have cracked from decades of freeze-thaw cycling, or flues that are oversized for modern gas appliances. A cracked liner cannot be swept safe - creosote penetrates the masonry, and combustion gases can leak into wall cavities. An oversized gas flue causes condensation that deteriorates the chimney from the inside. We’ll show you the camera footage, explain what the code requires, and tell you plainly when work can safely wait versus when it cannot. Call (571) 489-4365 to schedule a Level-2 inspection.
Neglected chimneys accumulate creosote, a flammable byproduct of wood combustion that ignites at approximately 451 degrees. A chimney fire can reach 2,000 degrees, cracking liners and damaging adjacent framing. In Dunn Loring’s older homes with original construction, that risk compounds because decades of deferred maintenance often mean hidden liner damage already exists. Gas systems pose a different hazard: blocked or deteriorated flues can force carbon monoxide back into living spaces. The cost of prevention is modest; the cost of remediation after a fire or CO event is not. Call (571) 489-4365 to book before the fall rush.
The Dunn Loring-Merrifield Metro station drives unusually brisk real estate turnover for a community this size, and Fairfax County inspectors are thorough. Most homes here were built with masonry chimneys designed for oil heat or wood fireplaces, and many were never properly modified when systems changed. A 60-year-old unlined flue venting a modern gas furnace, combined with a cracked crown from years of freeze-thaw exposure, routinely generates deficiency notices that must be cleared before closing. We perform these pre-sale inspections regularly and can often coordinate timing with your closing schedule. Call (571) 489-4365 to discuss your timeline.
Ready to get your chimney looked at? Call (571) 489-4365 any time - day, night, weekend. A live person will answer, ask what you’re seeing or smelling, and get you scheduled. We’ll bring the camera, take the photos, and give you a straight answer about what your chimney needs and what it doesn’t. Done right - and we stand behind it.

- Rashad Jackson"The liner was cracked in two places. He walked me through the options honestly, including the one that was cheaper for him and better for me."
- Xavier Freeman"Second property I have had them at. Both times the tech showed me photos from inside the flue before quoting anything."
