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.

Why Alcott Chimney Sweep Is Redwood City’s Preferred Chimney Inspection Company
Redwood City homeowners keep calling us for one reason above all: we show you the camera footage before we recommend anything. Ruben Castellano and his team came up through an industry where a $189 sweep too often turned into a $4,000 liner pitch backed by nothing you could see. We changed that rule. Every Level 2 chimney inspection includes video of the flue interior, shown to you on the spot, before any repair conversation starts.
You’ll know who’s coming before the truck turns down your street. Every technician is background-checked and identity-verified under the Threshold Standard, and we send the technician’s name and photo to your phone in advance. When they ring the bell, they show a photo ID badge. No exceptions. That matters in Redwood City, where a lot of us answer the door for service workers without knowing much about who’s standing there.
Every inspection comes with a written price before work begins and a written guarantee on any repair we do. If a repair fails within the guarantee period, the second visit is free. That covers the full year under our 365-Day Done Right Promise. We’ve operated since 2002 as part of the Threshold Group family of home-service companies, and our Redwood City customers get the same standard on every visit: verified tech, written price, written guarantee.
Chimney Camera Inspection in Redwood City
A chimney camera inspection in Redwood City is how we see what’s actually inside your flue liner, and it’s the backbone of our Chimney Inspection approach across the city. We run a high-resolution video camera up the flue and record the entire run: liner condition, mortar joints, blockages, animal nesting, and any hidden cracking. In Redwood City, this matters more than most people expect, because the flatland ranch homes built in the 1940s through 1960s often still run the original clay tile liner. On camera, the joints between those tiles are where cracks show up first. You watch the footage with us in real time.
When Flatland Clay Tile Flues Hide Problems
Homes near downtown Redwood City and along Stambaugh Hurst don’t burn fires often enough to build up dangerous creosote. What they do build up is worse in its own way. Birds and raccoons find uncapped clay tile flues and settle in. A camera inspection shows exactly how much debris is packed in there, where it sits, and whether the liner has cracked behind it. Without the camera, a technician is guessing from a flashlight and a mirror.
When a Hillside Chimney Needs a Closer Look
In Emerald Hills and Farm Hill, the camera tells a different story. Fog pushes in off the coast and saturates exposed brick for months, and moisture works into the mortar joints. The camera catches flue-side cracking before it becomes a full chimney rebuild. We don’t recommend liner work on fog-damaged masonry until we’ve inspected the entire stack first.
Fireplace Inspection in Redwood City
A fireplace inspection in Redwood City examines the firebox, damper, lintel, and smoke chamber, plus the visible masonry around the firebox opening. This is a separate step from the flue inspection itself, and in Redwood City’s older housing stock, it’s often where the most expensive silent problems live. Cracked firebrick in the firebox back wall, a damper rusted open from decades of fog-side exposure, a smoke chamber with gaps that let heat reach the framing behind the wall. You don’t see these from the living room couch.
Firebox Deterioration in Older Ranch Homes
The postwar tract homes around Redwood City were built fast, with fireplaces that used standard brick and clay flue tile. Sixty to eighty years on, the firebrick in the firebox has gone through decades of heating and cooling cycles plus whatever moisture wicked through the mortar from outside. A fireplace inspection maps the damage and tells you whether it’s cosmetic or structural. If you see cracks running diagonally through brick rather than along mortar lines, that’s a red flag we flag for a Level 2 camera look.
Dampers, Crowns, and the Fog Belt Factor
On an Emerald Hills or Farm Hill home, a fireplace inspection often finds a damper rusted in the partly-open position because moisture got to it year after year. That’s not cosmetic. An open damper lets conditioned air escape and lets fog-wet air keep the flue damp. The chimney crown also takes a beating on hillside homes, and when the crown cracks, water travels down the exterior masonry and eventually into the firebox itself. Our inspection reports note the crown condition even when you only called about the firebox, because around here, the two fail together.
Trusted Brands We Service in Redwood City
When repairs come out of a Redwood City inspection, we install what the trade specifies, not what a box store stocks. We carry DuraFlex liner systems, Olympia Chimney components, Famco caps and dampers, and Copperfield accessory parts on our trucks when we head out to Redwood City jobs. That means if your inspection finds a cracked clay tile that needs a liner or a failed damper plate, we’re often able to quote and schedule the fix on the same visit, without ordering parts from a distributor and coming back in two weeks. For the fog-belt homes on the hills, we keep stainless caps and weather-rated crowns in stock locally, because those accounts for a disproportionate share of Redwood City repair work.
Common Chimney Inspection Problems We See in Redwood City Homes
- Raccoon and bird nesting in uncapped flatland flues. The mild weather means fireplaces go unused for years, and the original clay tile flues in Stambaugh Hurst and downtown-adjacent ranches are open invitations. We remove the debris, camera-verify the flue is clear, then quote a proper cap.
- Spalling brick and cracked mortar on fog-exposed hillside chimneys. Emerald Hills and Farm Hill sit under marine fog for months, and the moisture cycling cracks mortar joints and pops brick faces. This shows up on inspection as surface spalling that will keep getting worse without repointing.
- Clay tile liners cracked at the joints in 60 – 80 year old homes. The original clay tiles in postwar Redwood City chimneys aren’t failing from overuse. They’re failing from age and thermal cycling. A Level 2 camera inspection shows the joint cracks clearly, and we walk you through what’s safe and what should wait.
- Modern furnaces vented into old flues never sized for them. We see this routinely across Redwood City: a high-efficiency furnace or water heater was installed in the 1990s or 2000s and vented into a masonry chimney built for an old open fireplace. The drafts don’t match, and the problem hides until a camera inspection reveals the mismatch.
Pricing for Chimney Inspection in Redwood City, CA
A Level 1 chimney inspection in Redwood City runs $189 – $249 for homes with a straightforward, accessible flue and no known problems. A Level 2 inspection, which includes the full camera scan of the flue interior, runs $289 – $389 and is what we recommend for any Redwood City home that hasn’t been inspected in years or has changed ownership, changed appliances, or survived a chimney fire. Level 3 inspections, which involve opening a wall to access hidden portions of the flue, are quoted case by case and rarely needed. What affects the price most in Redwood City is height and access: a custom hillside home on Farm Hill with a steep roof pitch costs more than a single-story ranch off Woodside Road. Call (336) 863-3889 and we’ll give you a firm written price before anything is booked.

FAQs About Chimney Inspection in Redwood City
Yes, and in Redwood City, rarely-used fireplaces often need inspection more than heavily used ones. Flatland homes that rarely burn fires sit uncapped for years, which invites raccoons and chimney swifts into the clay tile flue. That nesting material is a fire hazard and a carbon monoxide blockage risk even though you barely use the fireplace. A Level 1 inspection confirms whether you have a problem; a Level 2 camera scan shows exactly what’s in there. Call (336) 863-3889 to schedule, and we’ll walk you through what we find with footage, not just talk.
A Level 1 inspection checks the readily accessible parts of the fireplace and chimney with no special tools. A Level 2 inspection adds interior camera scanning of the flue and is required for any Redwood City home changing ownership, changing fuel type, replacing an appliance, or recovering from a chimney fire. A Level 3 inspection involves opening building structure to access concealed flue sections and is only needed when a serious problem is suspected. Most Redwood City homeowners need a Level 2 if it’s been more than a few years, because camera evidence is the only way to see clay tile joint cracks. We’ll tell you which level fits your situation and give you a written price before we book it.
The fog does it, not the fires. Emerald Hills and Farm Hill sit in a marine fog belt that keeps masonry damp for months at a time, and the repeated moisture cycling cracks mortar joints and pops brick faces even when the fireplace is rarely used. Spalling mortar on a fog-exposed Redwood City chimney is progressive; the damage compound each winter. Repointing now stops it from becoming a rebuild later. If you already have an inspection report from us, call (336) 863-3889 and we’ll walk you through exactly what the report showed and what a repair scope would look like.
No. Age alone is not a reason to replace a clay tile flue in Redwood City. We recommend a liner only when the camera footage shows cracks at the tile joints, gaps that allow heat transfer to adjacent framing, or a sizing mismatch with a modern appliance. If the flue is old but intact and properly sized, we’ll tell you that plainly and write it in the inspection report. We don’t sell liner replacements on fear, and we show you the footage before we discuss any repair. That’s exactly why our Chimney Inspection process starts with video evidence, not a sales conversation.
Sometimes, but not reliably. A flatland ranch home in Redwood City may have a clay tile flue that’s meant to have a cap but lost it to wind years ago, or it may have been built without one. From the ground, you can often see whether a cap is present on the flue tile, but you can’t see whether the cap is properly seated or whether the other flue tile was never capped at all. Our inspection includes a check of every flue tile opening from the roof or with a camera, not just a glance from the driveway. Call (336) 863-3889 for an exact inspection quote, and we’ll include the cap check as part of the written scope.
