Why Ashby Chimney Houston Is Nassau Bay’s Preferred Chimney Inspection Company
Nathan Corliss runs our Nassau Bay inspection work the same way we’ve operated since 2002: show up on time, put the price in writing before anything starts, and never recommend a repair without camera footage the homeowner watches alongside us. Homeowners in Nassau Bay have dealt with plenty of contractors who treat a chimney inspection as a sales call. We treat it as a diagnostic. The difference matters when someone tells you a liner needs replacing and you have no way to verify it.
Every technician who arrives at your Nassau Bay door is background-checked and in uniform, so you know exactly who’s walking in. Phones are answered by a live person around the clock, and if a repair we complete fails inside the guarantee period, we come back at no charge.

Level 2 Chimney Inspection in Nassau Bay
Level 2 Chimney Inspection in Nassau Bay is the standard we recommend for most homes here, because the clay tile liners installed when these houses were built in the 1960s and 1970s are now at the age where vertical cracks show up, and a Level 1 visual check can miss them completely. A Level 2 inspection sends a camera down the full length of the flue, checks the smoke chamber, and documents everything with video you can see yourself. In Nassau Bay, we also pay close attention to the metal components: caps, dampers, and flashing all take a beating from Clear Lake salt spray. A typical Level 2 camera inspection runs $249 – $349, depending on roof access and chimney height.
When Nassau Bay Homeowners Need a Level 2
You need a Level 2 inspection if you’ve bought or sold a home, if you’ve had a chimney fire, if you’ve changed the appliance venting into the flue, or if a storm has hit the roof and possibly damaged the stack. Real estate transactions in Nassau Bay almost always trigger a Level 2, and we do those inspections with the same camera documentation so buyers and sellers aren’t left arguing over opinions.
What the Camera Shows Us
The camera reveals what a flashlight can’t: hairline vertical cracks in clay tiles, gaps between tile sections, and corrosion on the metal throat damper. Nathan walks every Nassau Bay homeowner through the footage in real time. If a liner is cracked, you’ll see it. If it’s not, you’ll see that too. We don’t recommend a repair we can’t show you.
Chimney Leak in Nassau Bay
A Chimney Leak in Nassau Bay usually isn’t the flashing; it’s the corroded cap or damper letting water in from the top, and that’s true here more than almost anywhere else in the Houston metro because salt spray off Galveston Bay eats through galvanized components years faster than inland humidity alone. When salty rainwater runs down a clay tile flue, it accelerates the spalling that’s already started from decades of thermal stress. The leak shows up as water stains on the ceiling near the fireplace, efflorescence on the brick, or a musty smell in the firebox. A leak diagnosis inspection in Nassau Bay runs $189 – $289, which typically includes camera verification of the entry point.
Salt Corrosion Failure Pattern
On a 1970s ranch off Upper Bay Road, our tech found a Famco chimney cap rusted through from Clear Lake salt spray, letting rain run down a clay tile flue that was already spalling. We showed the homeowner the camera footage of the cracked liner and the corroded cap before recommending a DuraFlex liner and a new cap. No guesswork, just video proof. That’s the standard we hold for every Nassau Bay leak call.
Spalling Brick and Mortar
Decades of humid, salt-laden air break down the mortar joints and the brick faces around the smoke chamber. As that material drops, it can partially block the draft and push combustion gases back into the house. That’s not a cosmetic issue, and it’s not something we suggest fixing without first confirming the extent on camera.
Trusted Brands We Service in Nassau Bay
We stock and install components from manufacturers whose materials hold up better in a coastal environment: DuraFlex liners, Copperfield caps, HeatShield resurfacing products, and Gelco waterproofing. When a Nassau Bay inspection turns up a failed part, we don’t have to order from a catalog and wait a week, because we keep the common replacement components on hand. You see the brand name, the part, and the written price before any work begins, and the repair carries the Kingswell Guarantee in writing.

AfterCommon Chimney Inspection Problems We See in Nassau Bay Homes
- Corroded metal caps and dampers: Salt spray off Clear Lake and Galveston Bay rusts galvanized caps at a rate you don’t see in inland Houston suburbs. The cap fails first, then water gets in, then the clay tile liner starts spalling.
- Vertical cracks in 1960s-70s clay tile flues: Coastal freeze-thaw cycles, even the mild ones we get in Nassau Bay, put enough thermal stress on aging clay tile to crack it. A Level 1 visual inspection won’t catch this; only a camera will.
- Spalling brick around the smoke chamber: Humid, salty air has been working on these brick faces for half a century. Dropped debris narrows the flue passage and affects draft.
- Gas appliances vented into unlined or undersized flues: Many Nassau Bay homes have gas water heaters or furnaces vented into masonry chimneys never designed for that exhaust chemistry. That condensation is corrosive, and the flue needs to be checked for proper sizing and condition.

FAQs About Chimney Inspection in Nassau Bay
We recommend an annual inspection for Nassau Bay homes, even with light fireplace use, because the salt-air corrosion on caps and dampers happens whether or not you burn. Creosote is a fire risk, but in this climate, water intrusion and spalling are the bigger annual concerns. A Level 1 visual check is enough in most years; a Level 2 with camera is worth doing every three to five years, or sooner if you’ve had a storm. Call (903) 961-6496 to schedule, and we’ll help you set a sensible interval based on your chimney’s age and condition.
Nassau Bay sits closer to the open water of Clear Lake and Galveston Bay, which means more airborne salt getting driven onto your chimney by prevailing coastal winds. League City is farther inland and gets less direct salt spray. The cap on your 1970s chimney has had 50-plus years of that exposure, and once the galvanized coating fails, rust takes over fast. We replace it with a stainless or copper option, usually a Copperfield cap, and we’ll show you the corrosion before we recommend anything.
A Level 2 chimney inspection is a camera-assisted inspection of the entire flue interior, smoke chamber, and accessible exterior, and you need one in Nassau Bay when buying or selling a home, after a chimney fire, after a major storm, or when you’re changing how the chimney is vented. For most Nassau Bay homes built in the 1960s and 70s, we recommend one as the baseline inspection because the original clay tile liners are now at the age where cracks are common and invisible from the top. It runs $249 – $349, and you watch the footage with us.
Yes, and that’s a common setup in Nassau Bay ranches where the original wood-burning fireplace now vents a gas water heater or furnace. You need to make sure the flue is sized correctly for the appliance and that the liner hasn’t been degraded by condensation from the gas exhaust, which is more acidic than wood smoke. We inspect the full path with a camera and tell you exactly whether the venting is safe as-is or needs correction.
We run a camera down the entire flue and record what it sees. Vertical cracks in clay tile show up clearly on the footage, as do gaps between tile sections and spalled debris. You’ll watch the feed with our technician and see the exact crack before any repair recommendation is made. If the liner is intact, we’ll tell you that plainly. No one should tell you a liner needs replacing without showing you the proof. Call (903) 961-6496 to schedule a camera inspection in Nassau Bay.
