Frequently Asked Questions

We start by laying drop cloths around the firebox and setting up a vacuum with a HEPA filter so dust doesn't enter your living room. Then we run brushes from the top of the flue down, or from the firebox up, depending on access and roof pitch. After the mechanical brushing, we do a camera scan of the flue to check for cracked tiles, gaps in mortar joints, or hidden creosote pockets. You get a written summary with photos before we leave. The whole process takes one to two hours for a standard Pomona fireplace.

A standard sweep and Level 1 inspection takes between 60 and 120 minutes on most single-family homes in Pomona. If we're doing a Level 2 camera inspection, replacing a cap, or the flue has heavy creosote buildup, plan for closer to two hours. We book in a time window and call when we're on our way. You don't need to be home the entire time, but we do need access to the firebox and a clear path to the chimney from outside.

The National Fire Protection Association says annual inspection, with sweeping as needed. For Pomona homeowners who burn wood more than once a week during the November-to-February season, that usually means a sweep every year. If you burn only occasionally, every other year is often enough, provided the camera inspection shows a clean flue. Gas fireplaces need less frequent cleaning but still benefit from an annual check of the venting and damper. Our report tells you exactly when to schedule the next visit.

Yes. Gas fireplaces in Pomona homes still accumulate dust, debris, and occasionally nesting material in the venting, and the damper needs to be checked for proper operation. We inspect gas logs, the pilot assembly, and the venting path. Gas chimneys don't produce creosote, but they can still develop blockages that create carbon monoxide risk. If you've never had your gas fireplace checked in a Pomona home built before 1990, it's worth a visit.

No. We lay full drop cloths around the firebox and use a HEPA vacuum to control dust at both the firebox and the top of the chimney. Creosote is sticky and fine, so containment matters. In 13 years of sweeping chimneys across Pomona, Claremont, and La Verne, we've learned that the customers who worry about mess are the ones who notice if we miss a speck, so we treat the interior of your home like we'd want ours treated. If you see dust after we leave, call us and we'll come back.

Clear the area around the fireplace by moving furniture, rugs, or decor at least six feet back. If you have a screen or glass doors on the fireplace, leave them as is; we'll remove what's needed. If you burn wood, please don't use the fireplace the day of the appointment. Give the firebox time to cool completely before we arrive. If there are pets, having them in a separate room helps us work faster and keeps them calm while we're on the roof.

We install caps from Famco and Copperfield, both of which hold up well in Pomona's dry, sunny climate and the occasional hard rain. Famco caps are known for their stainless and copper construction, which resists the rust and UV degradation we see on cheaper galvanized caps after a few summers. Copperfield makes a reliable multi-flue option for the wider chimneys common on mid-century Pomona homes. We'll recommend the right size and material for your flue, not whatever's left on the truck.

Yes. When a camera scan shows cracked tiles, missing mortar, or gaps that expose the masonry to heat and moisture, we'll recommend a liner system. We work with DuraFlex and HeatShield products, both designed for the specific challenges of Southern California masonry chimneys: earthquakes, dry heat, and occasional heavy rain. DuraFlex is a flexible stainless liner suited for most Pomona fireplaces. HeatShield is a ceramic coating system that can repair damaged terra cotta liners without a full teardown. The right option depends on what the camera shows.

It depends on your chimney's condition. A stainless liner like DuraFlex is the stronger long-term choice for chimneys with severely cracked tiles or missing mortar joints. HeatShield bonds to the existing terra cotta and can be a good fit for minor-to-moderate cracking where the structure is still sound. We'll show you the camera footage, explain what we're seeing, and give you both options in writing. You decide. We don't push one system over the other unless the condition of your flue makes the choice obvious.

Yes. For prefabricated and factory-built fireplaces, the chase cover is the metal top that seals the framed chimney chase. Pomona's sun and occasional heavy rains rust out chase covers faster than people expect, and once water gets inside the chase, it travels down and damages ceilings and walls. We measure and install a properly fitted replacement, typically galvanized or stainless depending on your budget. Most chase cover replacements can be scheduled within a week in the Pomona area.

Every pro working under our name is required to hold the license and insurance their state requires. That means general liability coverage for property protection and workers' compensation for the team on your roof. Before you hire any chimney company in Pomona, ask for proof of insurance. An uninsured crew on your roof is a risk you don't want. We're glad to provide documentation when you book.

We handle the full range of chimney work, from sweeping and camera inspections to cap replacement, liner installation, crown repair, waterproofing, and masonry work. If your chimney needs a repair beyond our scope, we'll say so plainly and point you in the right direction. In Pomona, we regularly see cracked crowns on older homes in the historic districts, and that's work we do directly. You get one call for the entire chimney, not a list of subcontractors.

Most Pomona chimneys are swept from the roof, so yes, we'll be up there. We use roof ladders and take care not to damage tiles or shingles. For steep-pitch roofs or chimneys with difficult access, we adjust the approach, sometimes cleaning from the firebox up. Roof safety is a genuine concern for anyone working on a chimney, and we'd rather take the time to set up correctly than rush. If your roof has brittle tiles, let us know when you book so we can plan for it.

Yes. We work with property managers and landlords across Pomona, Montclair, and Ontario. A camera inspection with a written report gives you documented proof that the chimney was maintained, which is helpful for insurance and tenant relations. If you're turning over a rental, we can schedule the sweep and inspection between tenants and send the report directly to whoever manages the property. Call (855) 341-8132 and let us know it's a rental.

A chimney fire, smoke backing into the house, water visibly leaking through the ceiling near the chimney, or a strong gas smell from a gas fireplace are emergencies. If you see flames in the flue or hear a roar like a freight train from the chimney, call 911 first, then call us once the fire is out and the chimney has cooled. We cannot rush to an active fire, but we can assess the damage afterward and tell you whether the chimney is safe to use again.

Sweeps are booked, not dispatched by the hour. In the busy fall and early winter season, we're often scheduling a week or more out. In spring and summer, we can sometimes fit you in within a few business days. Our hours are Monday through Friday 7:00 AM to 7:00 PM, and Sunday 7:00 AM to 7:00 PM. We're closed Saturday. Call (855) 341-8132 and the coordinator will find the earliest slot that fits your schedule.

Water around the chimney usually means a cracked crown, failed flashing, or a damaged cap. In Pomona, the dry summers can mask a leak until the first heavy rain of winter, when it suddenly shows up as a stain on the ceiling. Until we can inspect it, put a bucket under the leak and, if safe, avoid using the fireplace. Don't assume the flashing is the problem without an inspection. We'll do a camera scan and an exterior check, then show you exactly where water is getting in and what it will take to stop it.

We stand behind every sweep with a straightforward satisfaction guarantee. If you're not happy with the work, call us and we'll make it right. For parts like caps and liners, manufacturer warranties apply, and we'll explain exactly what's covered and for how long before you approve any installation. We want you to feel confident that the money you're spending on your Pomona home's chimney actually solved the problem.

DuraFlex and HeatShield both carry manufacturer warranties that we'll walk you through at the time of the estimate. The warranty comes from the manufacturer, not from us, and we'll register the installation so the coverage is active. The honest truth is that a liner warranty is only as good as the installation, which is why we take photos before, during, and after so you can see the work yourself. If a warranty claim ever comes up, we help you file it.

Call us and we'll come back and look. If the repair was ours and it failed, we'll fix it under our workmanship guarantee. If it's a new issue, we'll show you the camera evidence and give you a straight answer about what's happening and what it will cost. Nothing about chimney work in Pomona should be a mystery. You get photos, a written report, and a company that answers the phone when you call.

You can, but climbing onto a Pomona roof with brushes and a shop vac is risky, and a homeowner-grade cleaning rarely removes the creosote that actually causes fires. Glazed creosote behind the smoke shelf, cracked flue tiles you can't see, and loose mortar joints go unnoticed without a camera. And chimney work means ladder work, which is where most DIY injuries happen. If you're going to burn wood through fall and winter, a professional sweep is the safest way to know your flue is actually clean.

Yes. Creosote is a flammable byproduct of wood combustion that builds up on flue walls. It ignites at around 450 degrees Fahrenheit, and a chimney fire can reach 2,000 degrees, cracking tiles, melting mortar, and spreading to the roof structure. In Pomona, where many homes are close together, a chimney fire becomes a neighborhood fire quickly. The good news is that a yearly sweep removes the fuel. It's the single most effective thing you can do to prevent a chimney fire.

Smoke entering the room instead of going up the flue, a strong campfire smell even when the fireplace isn't in use, visible black flakes falling into the firebox, or animals scratching in the chimney all mean it's time to call. In Pomona, squirrels and birds are particularly active in spring, and they love uncapped chimneys. Any one of these signs is enough to warrant a camera inspection. You don't need to wait for the annual visit if something feels off.

Yes, and a Level 2 camera inspection is the right call for a real estate transaction. Pomona's housing stock ranges from 1920s bungalows to 1980s tract homes, and chimney conditions vary wildly. A standard Level 1 inspection won't catch hidden liner damage or firebox cracks that a Level 2 camera scan will. For a few hundred dollars, you'll know whether the chimney is safe to use, what repairs are coming, and whether you want to ask the seller to address them before closing.
