Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Trusted Chimney Inspection for Arlington Homeowners
A chimney can look perfectly sound from the living room and still be hiding a cracked flue, a failing crown, or a creosote buildup dense enough to ignite. That gap between appearance and reality is exactly what an inspection closes. At Sentry Chimney Sweep, our technicians have up to 11 years of experience reading the parts of a chimney nobody sees, and we bring that knowledge to homes across Arlington. We work with professional-grade materials from brands like HeatShield and DuraFlex, so if the inspection turns up a problem, the fix meets trade standards rather than masking it. Same-day service is often available, and a formal inspection gives you a written record of your chimney’s condition. Call (833) 309-7302 to book.
Fireplace Inspection
Fireplace Inspection is the assessment of the firebox, damper, hearth, and surrounding masonry – the parts you actually use every time you light a fire. You need one when you’ve just moved into a home with a fireplace, when the fire draws sluggishly or smokes into the room, or when it’s simply been a few seasons since anyone looked. Sentry Chimney Sweep checks the firebox for cracked brickwork, tests the damper to confirm it seals and opens fully, and examines the hearth for heat damage. Most fireplace inspections run roughly $99-$189 for a straightforward open fireplace, though the written estimate always sets the final price. Call for an exact quote.
Firebox and Damper Assessment
We look at the mortar joints between firebox bricks and test the damper door for a tight seal. A damper that won’t close means warm air escapes all winter; one that won’t open lets smoke back into the room.
Hearth and Surround Check
The hearth and the masonry around the opening absorb heat and take the brunt of any spillage. We check for cracks and heat spalling that could let embers reach combustible material nearby.

Chimney Inspection Services
Chimney Inspection Services cover the whole stack, not just the fireplace: the flue, the crown, the flashing, the exterior masonry, and any attached appliance venting. You need them when a home changes hands, after a chimney fire or a strong storm, or on a routine schedule if you burn regularly. Sentry Chimney Sweep runs sweeping, repair, and inspection under one company, so you don’t have to coordinate three contractors to get one chimney sorted. Standard inspections typically run $99-$189, while a more involved Level 2 assessment climbs toward $199-$349 depending on access and how much camera work is needed. We use HeatShield resurfacing when the flue interior needs rebuilding rather than a simple cleaning. Call (833) 309-7302 for an exact quote.
What Inspectors Examine
We check the flue for cracks and gaps, the crown for crumbling, the flashing at the roof line, and the firebox for damage. Each area gets noted so you have a complete picture instead of a single alarming sentence.

Choosing an Inspector
Ask whether the company does both inspection and repair. When the same specialist can clean, fix, and report, there’s less incentive to overstate a problem to close a job.

Chimney Flue Inspection
Chimney Flue Inspection is the close look at the interior passage that carries smoke and gases out of your home – the part of the chimney you can’t see and shouldn’t guess about. You need it when you burn wood regularly, when you notice soot stains around the flue top, or after any sign that the liner has cracked. Sentry Chimney Sweep examines the flue for cracks, gaps between liner sections, and creosote buildup that has reached the glazed stage, which is the form most likely to fuel a fire. A flue inspection typically runs $149-$329 when camera work is involved, with the written estimate setting the final price. Call for an exact quote.
What the Flue Should Look Like
An intact flue should be smooth, continuous, and free of gaps at the joints. When a section of liner has cracked or separated, gases can slip out of the flue and into the surrounding masonry.
Why Creosote Matters
Creosote builds in layers, and when it thickens and glazes it becomes far harder to remove and far more combustible. Regular inspection catches it before it reaches that stage.
Chimney Fire
Chimney Fire is the combustion of creosote or soot inside the flue, and it can happen without anyone in the house noticing anything louder than a low roar or a shower of sparks from the top. You need an inspection after any suspected chimney fire, because a slow-burning one often cracks the liner and leaves a gap that only a camera can find. Sentry Chimney Sweep assesses the full flue after a fire, checks for cracked tiles or a failed liner, and recommends whether a DuraFlex liner system is needed to bring the chimney back to a safe standard. Post-fire inspection and any repair work typically start around $199-$349 for the assessment, with liner work quoted separately. Call (833) 309-7302 for an exact quote.
Signs a Fire Has Happened
Look for warped damper parts, puffy or discolored creosote, cracked flue tiles, and scorching around the top of the chimney. A fire can smolder quietly for a while before it’s noticed.
Carbon Monoxide Risk
A cracked flue lets carbon monoxide escape into the home instead of up the chimney. That’s the reason a post-fire inspection isn’t optional, and the reason a working carbon monoxide alarm belongs near any wood-burning appliance you use.
Level 2 Chimney Inspection
Level 2 Chimney Inspection is a more involved assessment that adds camera work and a check of accessible portions of the chimney, and it’s the standard inspection when a home is being sold or after an event that might have damaged the flue. You need one when you don’t know the chimney’s history, when the chimney has changed use, or when a Level 1 visual check turned up something worth a closer look. Sentry Chimney Sweep performs these with a flue camera so the findings are documented, not guessed at. A Level 2 typically runs $199-$349 in Arlington, depending on roof access and how much of the flue needs filming, with the written estimate setting the final price. Call for an exact quote.
When Level 2 Is Required
Real estate transactions, a change of fuel or appliance, and post-fire or post-storm situations all call for a Level 2. Some municipalities also require it when a home is sold.
What Makes It Different
Where a basic inspection is visual, a Level 2 adds a camera run through the flue and a look at accessible parts of the chimney interior. It catches what the eye alone can’t.
Chimney Leak
Chimney Leak is water getting in through the crown, the flashing at the roof line, or the masonry itself, and it’s one of the most common reasons a chimney starts to fail from the inside out. You need to address it as soon as you see water staining on the ceiling near the chimney, rust on the damper, or white powdery staining on the exterior brick. Sentry Chimney Sweep traces the source rather than sealing over it, checking the crown, the flashing, and the masonry joints for the actual entry point. Leak diagnosis and crown or flashing repair typically run $199-$449 depending on the extent of the damage, with the written estimate setting the final price. Call for an exact quote.
How Water Gets In
A crown that has cracked allows water to pool and soak into the masonry. Flashing that has pulled away from the roof line lets it run straight down the chimney chase.
Why Small Leaks Get Worse
Water that freezes in a crack widens it, and repeated freeze-thaw cycles over a Northern Virginia winter turn a hairline gap into a real opening. Catching it early saves the masonry.
Chimney Camera Inspection
Chimney Camera Inspection is the use of a video camera run through the flue to see and record conditions that a visual inspection can’t reach. You need it when a standard inspection turns up a possible crack, when a home has an older unlined or partially relined flue, or when you’re weighing the cost of a liner replacement. Sentry Chimney Sweep uses camera work to give you a documented record of the flue interior, so the recommendation comes from what the camera saw rather than what we assume. Camera inspections typically run $199-$329 as a standalone service or bundled with a sweep, with the written estimate setting the final price. Call (833) 309-7302 for an exact quote.
What the Camera Sees
It catches cracks, missing mortar joints between flue tiles, gaps at the liner connection, and any place where the flue lining has separated. It also lets us measure how much creosote remains after a sweep.
Getting the Footage
We record the run so you can review it yourself, and we walk through what the footage shows. If nothing is wrong, we say so plainly.
Brands We Service
We work with professional-grade equipment from names that chimney professionals specify on their own jobs. Famco products come up often in crowns and venting components, and we know where those parts tend to wear or fail first. Copperfield liners are another brand we see regularly, and we inspect them the same way we inspect any flue: with a camera and a careful eye on the joints.
DuraFlex liner systems are what we reach for when a flue needs relining, and we know how those systems are built and where they need to be supported to last. HeatShield resurfacing is our choice when the flue interior needs rebuilding rather than replacement. Whether you have DuraFlex, HeatShield, Copperfield, Famco, or any other make, we can help.

AfterSigns You Need a Pro Right Now
- Smoke drifting back into the room. A fireplace that pushes smoke toward you instead of up the flue is telling you something about its draft or blockage. That’s worth a look before the next fire.
- A strong creosote smell. The smell is strongest in humid weather and often means buildup has reached the glazed stage. It’s a fire risk, not just an odor problem.
- Water stains on the ceiling or masonry. Staining near the chimney or white powdery bloom on the brick points to an active leak. Water and masonry don’t mix well over time.
- Cracked or loose flue tiles. Even a visible crack in the flue top can mean gaps deeper down. A camera inspection is the only reliable way to know the extent.
- A chimney that hasn’t been looked at in a while. If you can’t remember the last inspection, that’s the reason to schedule one. It’s the cheapest way to find out what shape the chimney is in.
Our Process, Step by Step
- 1
Talk through the symptoms. We ask what you’ve noticed about the fireplace, any smells, drafts, or water intrusion, and whether the chimney has been inspected before. That shapes what we focus on.
- 2
Exterior and interior visual check. We examine the crown, flashing, masonry, firebox, damper, and hearth from the outside in. Anything that looks off gets noted for a closer look.
- 3
Sweep if needed. If creosote has built up, we clean the flue so the interior can be assessed clearly. It’s hard to inspect what you can’t see.
- 4
Camera run through the flue. A video camera goes down the flue to catch cracks, gaps, and failing joints. We record it so you can see what we see.
- 5
Written report and recommendations. You get a plain-language summary of the chimney’s condition, what needs attention now, and what can wait. Nothing is recommended without evidence you can review.
How Much Does Chimney Inspection Cost in Arlington?
Chimney inspection pricing in Arlington depends on which level of service you need and how much access the chimney allows. A typical standard inspection runs $99-$189 for a visual check of the firebox, damper, and accessible parts of the flue. A Level 2 inspection with camera work typically runs $199-$349, and post-fire assessments or leak diagnosis start around $199-$449 depending on what has to be uncovered. Several factors shift the price: whether a sweep is needed first, whether the roof is steep or access is tight, and how much of the flue has to be filmed.
To avoid overpaying, ask for a written estimate before work begins and make sure it separates inspection from any repair. You shouldn’t be told you need a liner without seeing the camera footage that justifies it. Everything we recommend comes with evidence you can review, and if the work can safely wait a season, we’ll tell you that too. Our estimate is free, and the written price sets the final cost.
