Frequently Asked Questions

We start by protecting the area around your fireplace with drop cloths, then run brushes through the flue from either the roof or the firebox depending on your setup. After the mechanical sweep, we use a camera to inspect the interior of the flue for cracks, gaps, or buildup we couldn't reach. You'll see those images yourself. We finish by vacuuming everything out and leaving the firebox clean. The whole process usually takes 45 to 90 minutes for a standard Irvine home.

Most sweeps in Irvine take between 45 and 90 minutes from start to finish. That includes setup, the actual sweeping, the camera inspection, and cleanup. If we find issues like a cracked flue liner or excessive creosote that needs a second pass, the appointment may run longer, but we'll tell you that at the start. Homes with steep roof pitches in areas like San Joaquin Hills or Turtle Rock can add time since roof access takes longer and requires extra safety setup.

The National Fire Protection Association recommends a chimney inspection at least once a year, and a sweep whenever creosote reaches 1/8 inch thick. For Irvine homeowners, the practical answer is this: if you burn wood more than twice a month during fall and winter, schedule a sweep every year before the season starts. If you use your fireplace rarely, every two years is often fine. Homes near the coast in Newport Beach or Corona del Mar can experience faster creosote buildup because damp ocean air causes soot to stick to flue walls more readily.

Yes, we clean and inspect gas fireplace vents and chimneys. Gas fireplaces don't produce creosote like wood fires do, but they can accumulate debris, dust, and even bird nests in the venting. More importantly, gas appliances can develop blockages or venting issues that create carbon monoxide risk, which is invisible and odorless. An annual inspection of a gas fireplace chimney in Irvine is a low-cost way to confirm everything is venting properly, especially in newer gas-log installations in homes around Woodbridge and University Park.

No, a professional sweep should leave your home exactly as we found it. We lay drop cloths around the fireplace, use vacuums with HEPA filters to capture dust at the source, and seal off the firebox opening with a specialized barrier before running the brush. The old image of soot pouring into the living room is from a different era of chimney work. Modern equipment, properly used, contains virtually all the debris. You shouldn't need to clean anything after we leave.

It depends on the chimney design and the type of buildup. Many Irvine chimneys can be swept entirely from inside the house using rotary brushes that run up from the firebox, which means no roof access at all. For chimneys with flat caps, spark arrestors, or heavy glazed creosote, roof access may be required. If we do need to go up, we use roof ladders and harnesses, and we're trained for steep-pitch and tile roofs which are common in communities like North Tustin and San Joaquin Hills.

Yes, inserts and wood stoves are actually where annual sweeping matters most. These appliances burn hotter and longer, and when they're connected to an older masonry chimney, the combination can accelerate creosote formation in the flue. We sweep the connector pipe and the full flue run, then inspect the liner for damage with our camera. In Irvine, many homes built in the 1970s and 1980s around Northwood have masonry chimneys retrofitted with inserts, and we work on those regularly.

We work with HeatShield and Gelco products for chimney liner repair and restoration. HeatShield is a ceramic coating system that seals cracks and gaps in existing flue liners without requiring a full rebuild. Gelco offers similar reinforced coating solutions. We also install and service components from Olympia Chimney and Famco where the job calls for caps, dampers, or accessory parts. The brand we recommend depends on your chimney's condition, which we document with camera images before making any suggestion.

HeatShield has a strong track record for restoring clay tile flue liners that have cracked or separated, which is a common problem in older Irvine homes. The process applies a ceramic material to the inside of the flue, creating a smooth, insulated surface that restores structural integrity and improves draft. It's often faster and less invasive than a full stainless steel reline, and it can be the right solution when the existing liner is still mostly intact. We'll show you the camera footage before recommending it, so you can see exactly why it's needed.

Olympia Chimney makes well-built chimney caps, dampers, and flashing components that hold up well in Irvine's coastal climate. We use their products on many jobs, especially where salt air from the coast accelerates rust on cheaper components. A quality chimney cap from Olympia can prevent rain intrusion, keep birds and rodents out, and stop downdrafts that push smoke back into the living room. If your cap is rusted through or missing, we can source and install the right Olympia part for your flue size.

Every professional working under our name is required to hold the license and insurance their state requires, and we carry liability coverage for the work we perform in your home. We're happy to provide documentation of insurance before any work begins. We've been serving Irvine and surrounding Orange County communities since 2014, and maintaining proper credentials is just part of how we operate. If you're comparing chimney companies, always ask for proof of insurance before anyone steps onto your roof.

Our technicians receive ongoing training in chimney sweeping, inspection, and repair, and every pro working under our name is required to meet the licensing and insurance standards for their state. We don't send untrained helpers to do chimney work. Chimney sweeping involves real skill: understanding draft mechanics, recognizing fire hazards, and operating on complex roof structures. In Irvine, where many homes have tile roofs and second-story fireplaces, that training matters. Ask any company you're considering who exactly will show up at your door and what training they've completed.

Look for three things: proof of insurance, a clear flat-rate price before the work starts, and a willingness to show you what they're seeing inside your chimney. Any company that won't provide insurance documentation or that prices by the hour without a cap should give you pause. In Irvine, you'll also want someone familiar with the specific roof types in your neighborhood, whether that's Spanish tile in Turtle Rock or composition shingle in Northwood. We've been working on Orange County chimneys since 2014, and we know the local housing stock well.

Smoke backing into your home, a visible chimney fire, or the smell of gas near your fireplace are all genuine emergencies that need immediate attention. For a chimney fire, call 911 first, then call us once the fire is out for an inspection before you use the fireplace again. If you smell gas, leave the home and call your utility company. For smoke drafting problems or water leaking around the chimney during rain, those are urgent but not immediate emergencies, and we'll schedule you as quickly as our calendar allows.

Our regular hours are Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. We're closed on Saturdays. If you have a chimney issue on a Saturday, leave us a message and we'll call you back first thing Sunday. For true emergencies like a chimney fire, call 911 directly, and for gas smells, call your utility provider. We handle non-emergency issues like leaks, draft problems, and smoke backing up during our normal business hours.

During fall and early winter, which is peak chimney season in Irvine, we're typically booking one to two weeks out. Outside of peak season, we can often schedule within the same week. If you're trying to get a sweep done before you start using your fireplace for the season, the best move is to call in late summer or early fall, before the rush hits. Call (855) 341-5439 and we'll find the earliest available slot that works for you.

Yes, repair work we perform comes with a warranty on both materials and workmanship. The specific terms depend on the type of repair, whether that's a liner restoration with HeatShield, a cap replacement, or masonry work. We put the warranty terms in writing before any repair begins, so you know exactly what's covered and for how long. We don't hide behind fine print. If something we fixed isn't holding up, call us and we'll make it right.

We stand behind our work. If you're not satisfied with the cleanliness of your chimney after we've swept it, call us and we'll come back to address it. The same goes for the inspection report. If you have questions about anything in the photos or the written findings, we'll walk you through them until you understand what you're looking at. Our goal is straightforward: when we leave your Irvine home, the chimney should be clean, the report should be clear, and you should know exactly what condition your system is in.

The price we quote for a sweep is the price you pay, period. We quote a flat rate over the phone before scheduling, and we confirm it in writing before work begins. If we discover something during the sweep that needs attention, we'll show you the camera evidence and give you a separate written estimate for that additional work, but we won't perform it without your approval. No surprise invoices, no "while we're here" upcharges. That's been our approach since 2014, and it's why Irvine homeowners keep calling us back.
