Frequently Asked Questions

A proper sweep covers more than shoving a brush up the flue. We start inside your home, protecting the hearth and floor, then brush the flue from the rooftop, working the creosote and soot down into a sealed vacuum. After the brushing we run a camera down the flue to inspect the liner, the smoke shelf, and the damper, and we check the cap, crown, and masonry from above. You get a photo report of what we found. Every recommendation after that is based on what you can see for yourself in those pictures.

Most North Hollywood sweeps take between 45 and 90 minutes from arrival to cleanup. A straight prefab chimney in a Sherman Oaks condo might go quicker. An older masonry chimney in a 1920s Studio City bungalow with heavy creosote can push the longer end of that range. The camera inspection and the report add a little time, but that's the part that shows you the real condition of the flue. We protect the flooring and furniture around the fireplace and sweep up all dust before we leave. The home looks like we found it, minus the soot that mattered.

For most North Hollywood wood-burning fireplaces, once a year is right, and the National Fire Protection Association standard is that a chimney should be cleaned when creosote reaches 1/8 inch thick, which in practical terms for regular fireplace users is about one burning season. Gas fireplaces can go longer intervals because they don't produce creosote, though an annual check for blockages and vent issues is still smart. If you use the fireplace every week in the cooler months, call us once a year before the heavier burning months. Call (833) 589-9860 to book your annual sweep.

Creosote is the tarry residue that forms when wood smoke cools as it rises through the flue and condenses on the liner walls. Around North Hollywood, the bigger factor isn't cold weather, it's the kind of fire people build: smaller, quick afternoon or evening fires that burn at lower temperatures. Those cooler fires produce more condensation and deposit creosote faster than a hot, full fire would. The resin content of the wood matters too. Oak and hardwoods are better than pine and other soft woods for keeping creosote lower, but even good wood creates some.

Yes, we service gas fireplaces and gas log sets across North Hollywood, Burbank, and Glendale. Gas doesn't produce creosote, but it does leave a fine white residue on the glass and the logs, and the venting still needs checking for blockages, nesting, and proper drafting. A blocked gas vent is a carbon monoxide issue, not a fireplace issue. We check the venting, the logs, the pilot, and the termination cap, and we note anything that affects how safely the unit operates. Annual service on a gas unit is less involved than a full wood sweep, and the estimate is per job.

It's more common in North Hollywood than people expect. The neighborhoods with old masonry chimneys, especially Toluca Lake and the older parts of Van Nuys, see nesting birds and raccoons in uncapped flues. We can't remove live animals, but we do find and remove nesting material, and we'll show you the blockage with the camera before and after. The real fix is a properly fitted cap with a screen, and we'll recommend one once the chimney is clear and cleaned. Blockages like this are also a reminder why a flue should be checked by someone who can see the entire length.

Almost always, yes. A flue that hasn't been cleaned in many years will have heavier creosote stages, possibly a tar-like glaze in the worst spots, and it will take longer to brush. But the process is the same, and the camera inspection after the brushing is even more important on a long-neglected chimney because years of creosote hide liner damage underneath it. If the flue was uncapped, there may be debris and animal nests too. We'll show you what was in there and what condition the liner is in once it's clean.

We install stainless steel liners like the DuraFlex system where a new continuous liner is the right call, and we use HeatShield as a resurfacing option when the original clay tile liner is still structurally sound but has small cracks and spalling. Which one fits your chimney is a judgment based on what the camera inspection shows, the age of the existing liner, and the chimney's intended use. No liner gets recommended or quoted until you have seen the inside of your flue and understand why the work matters.

Copper caps from a maker like Copperfield are popular on North Hollywood homes with architectural character, especially in the NoHo Arts District where homes have more decorative roof treatment. Copper holds up well, it develops a distinctive patina over the years, and it's a strong choice for long-term performance. A good cap matters more than the material though. The main job is keeping rain, debris, and animals out of the flue. The best cap is the one sized correctly for your chimney, with proper screening, and we'll fit it to your flue rather than selling you a universal piece.

If the cap is rusted through, bent beyond repair, missing its screen, or letting rain into the flue, replacement makes more sense than trying to clean around a failing part. Rain entering an uncapped or damaged chimney accelerates liner wear and can rust out dampers in older North Hollywood masonry fireplaces. We'll check the cap on every sweep, and if it needs replacing, we'll show you the condition and recommend a properly fitted replacement from a maker like Famco, sold as part of the free written estimate.

Every technician working under our name is required to hold the license and insurance their state requires, and we carry the coverage a homeowner in North Hollywood rightly expects when a contractor steps onto the roof. Ask if the company you're calling can say the same up front. Reputable chimney work in California should always involve a properly credentialed contractor, and we encourage you to verify it before any service. A professional sweep protects your home, your roof, and everyone who goes near the flue.

The technicians who serve the San Fernando Valley through Ashford Chimney Sweep are trained chimney professionals who work to the same standards you'd expect anywhere in the country, and they're required to have the proper state licensing and insurance. Chimney work isn't a trade where you want to take a verbal claim at face value. We're happy to have you ask about credentials when you call, and we will tell you plainly what applies to your job in North Hollywood, Sherman Oaks, or the surrounding area before anyone arrives at your home.

Yes, same-day service is possible when the schedule has an open slot. Call (833) 589-9860, let the coordinator know what you need, and we'll check the board for an opening that day. We answer 24/7, and fast dispatch runs from 7am to 7pm, Sunday through Friday. Same-day availability depends on the work being booked ahead of you, so the earlier you call, the better the odds. We'll confirm a window before anyone heads your way, and the estimate stays free whether we come that afternoon or later in the week.

A live coordinator answers, asks where the home is and what the chimney is doing (or not doing), then books your sweep into the next available opening. We answer 24/7, so the phone doesn't go to voicemail when you call. Fast dispatch runs from 7am to 7pm, Sunday through Friday. A call outside dispatch hours is answered and booked into the next opening. Before we arrive, you'll know the flat price for the sweep we agreed to. No surprises, no hidden trip charge, and the quote comes from the work we actually see, not a generic menu.

We're closed on Saturday. Dispatch runs Sunday through Friday, from 7am to 7pm, and the phone line is answered 24/7. So if you call on a Saturday, you'll still get a person who can book you into a Sunday slot or the next opening that works. If you need a sweep before the heavier burning season and the weekends are your only free time, Sunday is on the schedule. Call (833) 589-9860 and we'll find the first opening that fits.

Yes. If you're not satisfied with the sweep, tell us, and we'll make it right. The work we do in North Hollywood is backed by a satisfaction guarantee. That means the brush work, the inspection, and the photo report are all things we stand behind. We also never recommend a liner, a cap, or any other repair without showing you the camera evidence that supports it, so you never have to wonder if the recommendation was honest. If the work isn't done to your standard, we want to hear about it.

The liner products we install, including DuraFlex stainless systems and HeatShield resurfacing, carry their own manufacturer warranties, and the scope of what's covered depends on the specific product and the condition of the chimney it's going into. We'll walk you through what the warranty covers at the time of the estimate, before you sign anything. No one should bury warranty details in fine print after the fact. Call (833) 589-9860 and we'll talk through the product options for your North Hollywood chimney with real specifics, not a flashy promise.

Honestly, we don't recommend it. Climbing onto a roof in the San Fernando Valley with a brush from a big-box store and trying to properly scrub a flue is both physically risky and far less effective than a professional sweep with proper rods, brushes sized to your flue, and a camera to verify the result. If the chimney turns out to have a cracked liner, a partial blockage, or a failing cap, you won't know it because you won't be able to see it. A professional sweep in North Hollywood starts at a few hundred dollars, and it comes with a full inspection, a photo record, and insurance if anything goes wrong. The ladder work alone is a reason not to do this yourself.
