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 Lakewood Homeowners
A chimney can look fine from the living room and still hide a cracked flue, a failed crown, or a heavy creosote load that turns a cozy evening into a chimney fire. That gap between what you can see and what’s actually safe is why we inspect before we sweep, and why we show you the camera footage instead of just telling you what we found. Our technicians have up to 14 years of experience reading Lakewood flues, from the older brick chimneys near Belmar to the newer inserts climbing toward Green Mountain. A standard inspection and sweep can often be booked the same day. Call (888) 320-6023 to get on the schedule.
Fireplace Inspection
Fireplace Inspection covers the firebox, damper, smoke chamber, and the visible flue above the fire, so you know the whole assembly is safe to light. You need one when you’ve just moved into a Lakewood home, when the fireplace has sat unused for a season, or when smoke has started drifting into the room instead of up the flue. Oasis Chimney Sweep checks clearances, looks for cracked firebrick and deteriorated mortar joints, tests the damper, and confirms the smoke chamber isn’t stepped or rough enough to slow draft. A fireplace inspection in Lakewood typically runs $99-$250, depending on how much of the firebox needs close attention; the written estimate sets the final price.
What the Firebox Reveal Tells Us
Cracked firebrick and crumbling mortar let heat reach the masonry behind the firebox, which is where hidden damage starts. We tap and probe the joints rather than just glancing at them, because a hairline crack at the surface often hides a wider gap behind it. What we find there decides whether a simple repoint will do or whether the firebox needs relining.
Damper and Smoke Shelf Checks
A damper that won’t seal or open fully changes how the whole fireplace drafts. We test the plate, the pivot, and the frame, then look at the smoke shelf for soot buildup that can push smoke back into the room. If the shelf is warped or the damper is seized, that’s a repair we can quote on the spot.

Chimney Inspection Services
Chimney Inspection Services give you a documented picture of the entire venting system, not just the parts you can reach with a brush. You want one before your first fire of the season, after any chimney fire or earthquake-style settling, and whenever you’re buying or selling a Lakewood home. Oasis Chimney Sweep handles the sweep, the inspection, and any repair under one contractor, so nothing gets handed off and no finding gets lost in a referral. Chimney inspection services in Lakewood generally run $99-$350, with the range reflecting whether you need a basic visual check or a full video-assisted inspection.
Exterior and Crown Assessment
The crown, flashing, and brickwork above the roofline take the brunt of Colorado’s freeze-thaw cycles. We check for spalling brick, separated flashing, and a crown that’s cracked enough to let water in. Those are the defects that turn into interior leaks months later.

Venting and Appliance Connections
We confirm that the flue serving your fireplace or wood stove is the right size and that the connector pipe fits tightly. A loose connection or an undersized flue is a draft problem and a safety problem at the same time, and it’s one of the findings homeowners most often miss.

Chimney Flue Inspection
Chimney Flue Inspection is a close look at the inside surface of the flue, the passage your smoke actually travels. You need it whenever there’s been a chimney fire, a change in how the fireplace burns, or a liner of unknown age, and it’s the step that tells us whether the flue is sound enough to keep using. Oasis Chimney Sweep runs a camera down the flue to check for gaps, cracks, and separated liner sections that a visual check from the firebox can’t reveal. A flue inspection in Lakewood typically runs $150-$400 when combined with a sweep, depending on flue length and access; the written estimate sets the final price.
Liner Condition and Gaps
Clay tile liners crack, and a stainless liner can pull apart at a joint. Either one lets heat and gases reach framing or masonry that was never meant to see them. We photograph every gap we find so you can judge the repair for yourself.
Creosote Buildup Levels
Creosote comes in stages, from light soot to a glazed, tar-like layer that’s hard to remove and easy to ignite. We rate what we find and tell you plainly whether a standard sweep clears it or whether glazed creosote needs a different approach. That rating also sets how soon you should schedule the next sweep.
Chimney Fire
Chimney Fire damage is often invisible from the room, which is why a post-fire inspection matters even when the flames never reached the roof. You need one after any chimney fire, even a small one you think burned itself out, because the heat can crack tiles, warp a damper, or scorch framing without leaving obvious marks. Oasis Chimney Sweep inspects the full flue after a fire, documents the damage with camera footage, and tells you what’s safe to use and what isn’t. Post-fire inspection and assessment in Lakewood typically runs $150-$400, and any repair is quoted separately on a written estimate.
Assessing Heat Damage
A chimney fire can reach temperatures high enough to spall brick and crack clay tiles. We look for those cracks and for any distortion in the liner, because a compromised flue is the path heat takes toward the house. We show you the evidence before recommending anything.
When the Fireplace Must Stay Dark
If the flue is cracked or a liner section has failed, the honest answer is to stop using the fireplace until it’s repaired. That’s not an upsell, it’s the finding the camera supports. We’ll tell you exactly what needs fixing and what can safely wait.
Level 2 Chimney Inspection
Level 2 Chimney Inspection is the thorough, camera-based inspection you need for real estate transactions, after a chimney fire, or when you’ve changed the appliance or liner. It goes past the basic visual check and inspects every accessible part of the flue and the chimney exterior. Oasis Chimney Sweep performs Level 2 inspections with video equipment and gives you a written report with photos you can share with a buyer, seller, or insurer. A Level 2 inspection in Lakewood generally runs $250-$500 depending on the chimney’s complexity and access.
Real Estate and Sale Transactions
Buyers and their agents expect a documented inspection before closing, and a Level 2 report gives them a clear picture. We list what’s sound, what needs repair, and roughly what that repair involves. It’s the same report we’d want if we were the ones buying.
Video Report With Photos
Every Level 2 inspection ends with a report you can keep and read at your own pace. The photos show the actual condition of the liner, crown, and flashing. You’ll have the evidence in hand when you decide what to do next.
Chimney Leak
Chimney Leak problems usually start at the top, where a failing crown, cracked flashing, or open mortar joint lets water into the masonry. You need an inspection when you notice water stains on the ceiling near the chimney, rust on the firebox or damper, or a musty smell after rain. Oasis Chimney Sweep traces the leak to its source rather than sealing everything in sight, then repairs the crown, flashing, or masonry with the right materials for the job. Leak diagnosis and repair in Lakewood typically runs $300-$500 for the diagnosis and minor sealing, with larger masonry repairs quoted separately on a written estimate.
Flashing and Crown Repairs
Flashing is where the roof meets the chimney, and it’s the most common leak point on a Lakewood roof. We reseal or rebuild it with proper counter-flashing rather than a smear of caulk. A cracked crown gets repaired or replaced so water sheds away from the flue instead of into it.
Water Stains and Rust
Rust on the damper or firebox means water is already getting in, and a stain on the ceiling near the chimney usually means it’s been happening a while. Those signs point to masonry that’s absorbed moisture and needs to dry and be sealed correctly. We check the whole path before we recommend a repair.
Chimney Camera Inspection
Chimney Camera Inspection puts a video scope down the flue so you can see what the technician sees, joint by joint. You need one whenever the flue’s condition is unknown, after a fire or a liner repair, or when a basic visual check turns up something worth a closer look. Oasis Chimney Sweep records the run and walks you through the footage, pointing out cracks, gaps, and offsets that a flashlight can’t reach. A camera inspection in Lakewood typically runs $150-$350 on its own or is included with a Level 2 inspection.
What the Scope Sees
The camera shows the full interior surface, including the smoke chamber and the top of the flue. That’s where cracks and separated tiles hide. Seeing the footage yourself takes the guesswork out of the recommendation.
Recording and Documentation
We record the inspection so you have a reference for next season and a record if you sell the house. Photos from the run go into your written report. That documentation is what separates a real inspection from a quick glance.
Brands We Service
We work with professional-grade product lines because the brand matters when a repair has to last. DuraFlex flexible liner systems are what we reach for on older or irregular flues, where a rigid liner won’t follow the shape of the chimney; the flexibility lets the liner fit the flue you actually have instead of asking it to fit a standard shape. HeatShield is our repair-first option for a liner that’s worn but not failed, a ceramic resurfacing system that restores the flue from the inside when full relining isn’t necessary.
Copperfield and Famco are part of the same roster, covering the masonry and component side of chimney work, so the repair matches the diagnosis. Recognizing where each brand’s products wear and how they’re installed is what lets us recommend the right fix rather than the easiest one. Whether you have a DuraFlex liner, a HeatShield-restored flue, or any other make, we can help, and if the right answer is one of these brands, it’s the one we’ll quote.

AfterSigns You Need a Pro Right Now
- Smoke rolling back into the room. A fireplace that smokes when it used to draft cleanly usually has a blockage, a failed damper, or a flue that’s lost its seal. Smoking is your first warning that the venting system has changed, and it’s worth an inspection before the next fire.
- A strong creosote smell or visible glaze in the flue. Glazed creosote is the stage that ignites most easily, and it doesn’t come off with a standard brush. If you smell it or see it, the flue needs a closer look before you burn again.
- Water stains, rust, or a musty smell after rain. These point to a chimney leak getting into the masonry or the firebox. Water and heat don’t mix well in a chimney, and the earlier the source is found the smaller the repair.
- Cracked or crumbling brick on the chimney exterior. Spalling brick and loose mortar let water in and weaken the structure over time. A chimney that’s shedding its surface needs an inspection before another freeze-thaw winter works it further.
- You’ve just moved in or the fireplace has sat unused. An unknown flue is an unknown risk, and a short inspection settles it. It’s the cheapest way to know what you actually bought.
Our Process, Step by Step
- 1
Book the visit and note the symptoms. We ask what you’ve noticed: smoke, smell, water, or nothing at all. That history shapes where we look first. Then we schedule the visit, and a standard inspection and sweep can often be booked the same day.
- 2
Protect the room and sweep first. We lay drop cloths and set up containment before any brushing starts, so soot stays in the flue and not on your floor. Sweeping first means the camera sees the actual liner surface, not a layer of soot.
- 3
Run the camera and check the components. The video scope goes down the flue while we check the damper, firebox, crown, and flashing. We photograph what we find at each point. That’s how a finding becomes evidence rather than a guess.
- 4
Walk you through the footage and the report. We show you the footage and explain what it means in plain terms, including what can safely wait. You get a written report with photos you can keep. Nothing is recommended without the camera evidence to back it up.
- 5
Quote the repair and finish the job. If a repair is needed, we quote it on a written estimate using the right material, whether that’s HeatShield ceramic resurfacing or a DuraFlex liner. Oasis handles the sweep, the inspection, and the repair, so there’s no handoff mid-problem. The written estimate sets the final price.
How Much Does Chimney Inspection Cost in Lakewood?
A typical chimney inspection in Lakewood runs $99-$350, with the range depending on whether you need a basic visual check with a sweep or a full video-assisted Level 2 inspection. A camera inspection on its own typically runs $150-$350, a fireplace inspection runs $99-$250, and a Level 2 inspection runs $250-$500. Those are estimates for planning; the written estimate sets the final price.
Several things move the number. Flue length and access matter, since a tall chimney or a steep roof takes longer to inspect. So does condition: a flue with heavy glazed creosote or visible damage needs more camera time and a longer report. A real estate transaction calls for a Level 2, which is more involved than a standard check. Adding a sweep to an inspection doesn’t usually add much, because the sweep is what lets the camera see the bare liner.
To avoid overpaying, ask for the written estimate before work starts and ask what level of inspection you’re getting. A quote that doesn’t specify Level 1, 2, or 3, or one that recommends a repair before anyone has run a camera, is worth a second look. Our estimates are free, and the report you get includes the camera evidence behind every recommendation, so you can see for yourself what needs fixing and what can safely wait. If the honest answer is that the flue can hold for another season, that’s what we’ll tell you.

Frequently Asked Questions About Chimney Inspection in Lakewood
A chimney inspection is a check of the firebox, damper, smoke chamber, flue, crown, and flashing to confirm the whole venting system is safe to use.
