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 know Gilroy’s particular mix of housing stock because we work it every week during burning season. Tract-built prefab fireplaces from the 1980s and 1990s east of Highway 101, the older brick chimneys near downtown and around Monterey Street, and the freestanding wood stoves that heat rural homes west toward the Santa Cruz foothills each fail in different ways. Our Chimney Inspection team is trained to spot all three before they become a fire or carbon monoxide problem.
Why Alcott Chimney Sweep Is Gilroy’s Preferred Chimney Inspection Company
We have been inspecting chimneys since 2002, and we built our reputation in cities like Gilroy on something simple: you know exactly who is pulling into your driveway before they arrive. Every Alcott technician is background-checked and identity-verified through the Threshold Standard, and we send you their name and photo before the appointment. When they ring the bell, they show a photo ID badge. No exceptions, every visit.
Gilroy homeowners regularly tell us the same thing in follow-up calls: the inspector showed up when we said he would, explained what the camera found without pushing a repair, and handed over a written price before any work was quoted. That is not an accident. Ruben Castellano built this company on the principle that a homeowner who can see proof of a problem, with their own eyes on our camera screen, will make a sound decision. We do not sell repairs that the camera does not show.
Response time to Gilroy is typically 2 – 4 business days during the fall rush, and often faster outside the October – December peak. Every phone call is answered by a live person, around the clock. If something smells wrong tonight, someone picks up. No voicemail tree, no callback queue.
Fireplace Inspection in Gilroy
Fireplace Inspection in Gilroy means something specific here: a large share of the homes east of Highway 101 and through the newer subdivisions near Christopher Ranch were built between 1985 and 2005 with prefabricated, zero-clearance fireplaces. Those units are now 25 – 40 years old, and many have never had their interior panels or gaskets looked at. A fireplace inspection on one of these homes includes checking the firebox panels for hairline cracks, testing door gasket seals, verifying the flue pipe connection, and running a camera up the chase to look for animal debris or panel separation. Gilroy pricing for this runs $199 – $299 when it is part of a standard cleaning visit.
Prefab Panel and Gasket Checks
Factory-built fireplaces do not fail the way masonry chimneys do. The refractory panels inside the firebox crack from repeated heating cycles, and when they do, heat reaches the metal shell behind them. Door gaskets flatten over time and lose their seal, which changes how the fire draws and can let combustion byproducts into the room. We check both on every prefab inspection in Gilroy.
Downtown Masonry Fireplace Checks
The older homes around downtown Gilroy, particularly near Monterey Street and along Sixth Street, often have original brick masonry chimneys from the 1910s through the 1940s. Many lack tile liners entirely, and decades of seasonal fires plus summer heat stress have taken a toll on the mortar joints. We inspect these with a camera to confirm liner condition before anyone lights a fire in them for the season.
Chimney Inspection Services in Gilroy
Chimney Inspection Services in Gilroy cover the full range from a basic Level 1 visual check to a full Level 2 camera inspection of the entire flue interior and exterior. A Level 1 inspection, which is appropriate when nothing has changed about how you use the fireplace or stove, runs $149 – $199. A Level 2 inspection, which includes camera work and is required for real estate transactions, after a chimney fire, or when you have made a fuel or appliance change, runs $249 – $399 in most of Gilroy.
Real Estate Inspections
Selling a home in Gilroy means the buyer’s inspector will usually flag the chimney. A Level 2 inspection with camera documentation gives you a written report you can hand to the buyer, or use to negotiate what is actually needed versus what their agent worries about. We perform these regularly across Gilroy, including rural sales off Santa Teresa Boulevard where wood stoves are common.

Wood Stove Flue Inspections
On Gilroy’s rural fringe, the appliance doing the heating is usually a freestanding wood stove, not a decorative fireplace. These are workhorses that run November through March, and the flue liner inside them builds creosote far faster than a suburban fireplace. Our inspectors ask how many cords you burn each winter before quoting anything, because the answer changes what kind of inspection and treatment you actually need.

Common Chimney Inspection Problems We See in Gilroy Homes
- Third-degree creosote glaze in rural wood stove flues. Properties off Hecker Pass Road and in the foothills that burn wood as primary heat produce a hard, shiny tar glaze that a standard brush cannot remove. This requires a chemical treatment, and it is the single most common finding on rural Gilroy inspections.
- Missing or rusted spark arrestors on wildland-interface parcels. Gilroy is ringed by dry grassland and chaparral. A chimney cap without a functioning spark arrestor turns every fire you light into a potential ignition source for the open land around you. We flag this on every inspection, not as an upsell, but as a fire-safety issue.
- Cracked refractory panels in 1980s – 2000s prefab fireplaces. The tract homes built during Gilroy’s rapid expansion east of Highway 101 are now hitting the age where prefab firebox panels fail. Homeowners do not notice because the cracks are inside the firebox, behind the glass or screen, where nobody looks during a routine cleaning.
- Unlined or deteriorated flues in pre-war downtown homes. The older brick chimneys near Monterey Street frequently lack tile liners, and where liners exist, decades of thermal cycling in Gilroy’s hot summers and cold winter nights have cracked them. A camera inspection is the only way to confirm liner integrity before the burning season starts.

FAQs About Chimney Inspection in Gilroy
A rural Gilroy wood stove used as primary heat should be inspected every 6 burning months, not every 12. Most stove manufacturers recommend an inspection at the start of each season and a cleaning after every 1 – 2 cords burned. Since a foothill property off Hecker Pass or Frazier Lake Road routinely burns 3 – 5 cords per winter, that means a mid-season check is often warranted for safety. Call (336) 863-3889 and we will help you figure out the right interval for your actual burn rate.
Most Gilroy homes getting a routine pre-season check only need a Level 1 inspection, which is a visual examination of the accessible chimney interior and exterior with no special equipment. You need a Level 2 inspection, which includes a camera scan of the full flue, if you are buying or selling the home, if you have changed fuel type or appliance, after a chimney fire, or after an earthquake or major storm. A Level 3 inspection is reserved for cases where hidden damage is suspected inside the chase or structure. Call (336) 863-3889 and describe your situation; we will tell you honestly which level applies.
Your Gilroy chimney needs a spark arrestor inspection because much of the city sits at the edge of wildland-urban interface terrain, where dry grassland and chaparral within feet of your chimney cap can catch from an errant ember. A missing or rusted-through spark arrestor is a direct wildfire ignition risk on rural parcels, and it is one of the cheapest problems to fix. We check every arrestor on every visit and replace them when they have rusted or blown off. Call (336) 863-3889 to have yours looked at before the next burn.
Your 1980s prefab fireplace inspection should cover the firebox refractory panels for cracks, the door gasket seal, the flue pipe connection at the top of the unit, the chase cap and spark arrestor, and a camera scan of the interior flue to check for panel separation or animal debris. These zero-clearance units from the mid-1980s through early 2000s tract expansion in Gilroy are now 25 – 40 years old, and many are past their manufacturer-rated service life. Call (336) 863-3889 to schedule a prefab-specific inspection, and we will walk you through exactly what the camera shows.
Third-degree creosote is a hard, shiny, tar-like glaze that forms when wood smoke condenses on a relatively cool flue liner, especially in stoves that run hot for long stretches as primary heat. No, a standard brush cannot remove it, and attempting to scrape it will damage the liner. It requires a chemical treatment, often applied in stages over one or two visits, to break the glaze down so it can be safely swept. On Gilroy’s rural fringe, we see this constantly on wood stoves burning 3 or more cords a season. Call (336) 863-3889 and we will tell you whether chemical treatment is necessary for your flue, with a written price before any treatment starts.
We were called to a rural property off the Hecker Pass corridor where the homeowner ran a freestanding wood stove as their only heat through the November-to-March season. Our tech found third-degree creosote glazed across the flue liner, that tar glaze a brush cannot touch, and a missing spark arrestor on the chimney cap. Given the dry chaparral and grassland surrounding the parcel, that missing arrestor was a genuine wildfire liability. We treated the glaze, replaced the arrestor, and walked the homeowner through burn practice to slow the next cycle of buildup.
