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.

AfterFast, Reliable Chimney Inspection Across Portola Valley
Chimney inspection in Portola Valley typically runs $189 – $549 depending on the level of inspection your chimney needs, with Level 2 camera inspections most common in this town because of the San Andreas Fault. We schedule most Portola Valley inspections within 3 – 5 business days, and unlike most chimney companies, you’ll know exactly who is coming before the truck turns onto Portola Road.

Call (336) 863-3889 and a live person will answer, day or night.
Why Alcott Chimney Sweep Is Portola Valley’s Preferred Chimney Inspection Company
We’ve been inspecting chimneys since 2002, and Portola Valley presents a set of conditions we don’t see in neighboring communities. The fault trace, the marine fog, the heavy tree canopy over most lots, and the custom masonry work on older estate homes all combine to make a Portola Valley chimney inspection a genuinely different job than the same service in Menlo Park or Palo Alto. Our techs understand what a displaced flue tile looks like on camera after a moderate shake, and they know how salt-laden marine air eats through galvanized caps along the Portola Road corridor faster than anywhere else in the area. That local knowledge matters.
Every customer gets a written price before any work begins, and every inspection includes a written report with photos you can actually see. We don’t recommend repairs without showing you the camera footage first. That’s the Alcott standard: you see what we see, and you decide with real information in front of you. You’ll also get something most chimney companies in Portola Valley won’t offer: a 365-Day Done Right Promise on any repair we complete, which means if something fails within a full year, we come back free. Not a prorated credit. A second visit at no charge.
When you book with us, you’ll receive the technician’s name and photo before the visit. They’ll show a photo ID badge at the door, every time, no exceptions. That’s the Threshold Standard, and it’s not an optional upgrade. For homeowners in Portola Valley who often work from home or have young kids in the house during the day, knowing exactly who is arriving before you open the door isn’t a nice-to-have. It’s the reason many of our Portola Valley customers call us in the first place.
Chimney Camera Inspection in Portola Valley
A Chimney Inspection with a video camera is the only reliable way to see what’s actually happening inside the flue of a Portola Valley chimney. We run a high-resolution camera down the flue from the top and also up from the firebox when needed, capturing every inch of the liner, the smoke chamber, and the crown from inside. The camera shows us cracks, offsets, missing mortar, creosote glazing, and the hidden fire channels that routine sweeps miss entirely. In Portola Valley, where a shifted flue tile can sit invisibly behind a clean-looking firebox after any quake above M4.0, the camera isn’t a luxury add-on. It’s the only thing standing between you and a chimney fire you can’t see coming.
A camera inspection in Portola Valley typically runs $229 – $489 when bundled with a sweep. What drives the price is the height of the flue, the condition of the cap, and whether we need to access the roof from a steep grade or work around tree limbs hanging over the crown. Most estate homes here have two or three masonry fireplaces, so by the time we’ve scoped all of them, the cost is toward the upper end of that range.
Level 2 Camera Inspection After Seismic Activity
Any time the Bay Area experiences a quake stronger than M4.0, we recommend a Level 2 inspection, which includes the full camera scope. The San Andreas Fault runs directly through Portola Valley, and the Portola Road corridor sits right on the trace. A moderate shake can displace flue tiles enough to create a fire channel while everything still looks fine from the hearth. That’s the failure mode that scares us, and it’s the one a camera catches.
Camera Evidence Before Any Repair Recommendation
We never recommend a liner, a crown rebuild, or anything else without camera footage you can review yourself. You’ll see the crack, the offset, the rust-through. If the camera shows a flue in good shape, we’ll tell you that too, and you’ll save money. No scare-selling, no invented hazards. Just the actual condition of your chimney, documented.
Fireplace Inspection in Portola Valley
A Portola Valley fireplace inspection covers more than the flue. We check the firebox, the damper, the smoke chamber, the hearth extension, and the exterior chimney structure from the crown down to the flashing. Homes in Portola Valley, especially those built between the 1960s and 1990s, often have multiple masonry fireplaces with original dampers that have warped from decades of use and flue tiles that were never designed for the seismic reality of this town. A fireplace inspection costs $189 – $349 depending on how many fireplaces you have and whether we’re doing a visual-only check or adding camera work.
Firebox and Damper Evaluation
We measure clearance to combustibles, examine mortar joints for spalling, and test the damper to make sure it opens and seals correctly. A warped damper on a fog-belt night lets cold marine air pour down the chimney, dropping flue-gas temperatures and accelerating creosote glazing. That’s the cycle we see constantly on properties along Alpine Road and throughout the western hills.
Crown, Cap, and Flashing Assessment
Salt-laden air from the coast gets funneled through the mountain saddle Portola Valley sits in, and it settles on the metal components at the top of your chimney first. We check the cap, the flashing, and the crown for corrosion, pitting, and rust-through. Galvanized components fail fast here. Stainless holds up. We’ll show you the difference and tell you honestly whether your cap can wait or needs replacement now.
Trusted Brands We Service in Portola Valley
We install and service components from Olympia Chimney, Copperfield, and DuraFlex, and we keep common parts stocked for faster turnaround on Portola Valley jobs. When a rusted cap or failed flashing needs replacement, we don’t order from a box store. We use stainless components from the same manufacturers chimney professionals specify, because the marine air and fog pattern here will eat a galvanized replacement within a few seasons. If your existing system uses any of these brands, our techs know the product lines and can match components correctly the first time. Call (336) 863-3889 and we’ll tell you what we have on hand for your chimney.
Common Chimney Inspection Problems We See in Portola Valley Homes
- Displaced flue tiles after seismic activity. The San Andreas Fault trace runs through the Portola Road corridor, and moderate shakes shift masonry flue tiles out of alignment. A camera inspection from above is the only way to find the offset before it becomes a fire channel.
- Corroded caps and flashing from marine air. The cool, moisture-laden air that funnels through Portola Valley each evening accelerates rust on galvanized chimney components. We see caps rusted through in five to seven years here where the same part would last fifteen years in Atherton.
- Stage 2 and Stage 3 creosote glazing. Low flue-gas temperatures on foggy nights create the exact conditions for tar-like creosote that hardens and can’t be brushed away. This glazed creosote is a fire hazard that requires professional removal, often with a chemical treatment or rotary chain system.
- Debris-blocked flues and squirrel damage. The oak, madrone, and redwood canopy over Portola Valley lots drops organic material onto chimney crowns constantly, and the crowns double as squirrel and bird habitat. We regularly pull nests and debris out of flues that haven’t been inspected in years.

FAQs About Chimney Inspection in Portola Valley
Because the San Andreas Fault runs directly through Portola Valley, specifically along the Portola Road corridor, while Palo Alto sits on flatland geology that doesn’t experience the same ground movement. A quake above M4.0 can shift flue tiles in a Portola Valley chimney without leaving any visible damage from the outside, and a displaced tile creates a hidden fire channel into your framing. Your Palo Alto friend’s chimney sits on stable ground. Yours sits on the fault trace. That’s the difference. Call (336) 863-3889 after any Bay Area quake above M4.0 and we’ll scope the flue.
Yes, and the reason isn’t how often you burn, it’s what’s happening to your chimney when you’re not burning. The marine fog that settles over Portola Valley each evening condenses inside the flue and mixes with creosote from even light burning, creating acidic deposits that eat away at masonry. The tree canopy drops debris and invites squirrels and birds into the crown. And the seismic risk means a once-a-year check with a camera is the cheapest insurance you can buy against a five-figure chimney rebuild. A standard annual inspection runs $189 – $249 for a visual check and $349 – $489 with camera. That’s a small number compared to the alternative.
The marine air that funnels through Portola Valley’s mountain saddle carries salt and moisture that corrodes metal chimney components much faster than in inland communities. Galvanized caps, flashing, and spark arrestors rust through in five to seven years here where the same parts would last fifteen years in Los Altos. The crown starts spalling as salt-laden moisture freezes and thaws in the masonry. Stainless components hold up against this exposure, which is why we install stainless caps and flashing on Portola Valley chimneys and recommend checking galvanized parts every single year. Call (336) 863-3889 for a free estimate on replacement components.
A Level 1 inspection is a visual check of the accessible portions of the chimney, including the firebox, damper, and exterior, and it’s appropriate when nothing about the system has changed since the last inspection. A Level 2 inspection adds a full camera scope of the flue interior and is required whenever you’re selling the home, after any seismic event, after any chimney fire, or if you’ve made changes to the appliance or fuel type. A Level 3 inspection involves removing portions of the chimney structure to access concealed areas, and we only recommend it when a Level 2 camera inspection shows evidence of hidden damage that requires a closer look. In Portola Valley, most homes we inspect need a Level 2 because of the fault and the fog-belt conditions.
If the cap is rusted through, it needs to come off and be replaced, and we’ll show you the corrosion before we touch anything. A rusted cap isn’t just an eyesore. It lets rain and fog directly into the flue, which accelerates masonry damage and creates the damp conditions that make creosote glazing worse. We can sometimes clean around a rusted cap for a short-term solution, but leaving it in place is false economy. Replacement caps for Portola Valley chimneys typically run $150 – $400 installed depending on the size and material. We’ll give you a written price before any cap work starts, and we recommend stainless for this location. Call (336) 863-3889 and we’ll tell you what you need.
