Frequently Asked Questions

We seal the fireplace opening, run a HEPA-filtered vacuum, and brush the full flue from the roof or firebox with appropriately sized wire or poly brushes. After brushing, we remove the accumulated creosote, soot, and any nesting material from the smoke shelf and firebox. Then we run a camera up the flue so you can see the result. The whole job takes 45 to 90 minutes for a standard Chino Hills fireplace. We leave the hearth cleaner than we found it and take the debris with us.

A straightforward cleaning in Chino Hills takes under two hours from setup to final walkthrough. Heavily glazed flues, animal removal, or difficult roof access can stretch that to three hours. If we're installing a cap or replacing a damper during the same visit, expect to add another 30 to 60 minutes. We book by appointment during our regular hours, Monday through Friday 7 AM to 7 PM and Sunday 7 AM to 7 PM, so you're not waiting around all day.

Yes, gas logs and gas inserts need service for different reasons than wood burners. Gas produces acidic condensation that corrodes flue liners and clogs burner ports with soot and dust. In Chino Hills, gas fireplaces often go years between cleanings because homeowners assume they're maintenance-free. We inspect the log set, clean the burner, check the venting, and look for carbon monoxide leaks at the connection points. If you smell gas or the flames burn yellow instead of blue, call us before running it again.

The National Fire Protection Association standard, which we follow, is that chimneys need cleaning whenever creosote buildup reaches 1/8 inch, and at minimum once per year for wood burners. In Chino Hills, the dry air and occasional Santa Ana winds mean creosote dries quickly and flakes, which is actually more dangerous than sticky buildup. If you burn more than two cords a season or burn unseasoned wood, schedule twice a year. Gas fireplaces can go two to three years between cleanings.

Most Chino Hills chimneys are cleaned from the roof because that gives us access to the full flue length and lets us inspect the crown and cap while we're up there. Some single-story homes with straight flues can be done from the firebox with the right equipment. We'll know after looking at your setup. Either way, we protect the interior with drop cloths and run a HEPA vacuum at the fireplace opening so no soot escapes into your living room.

Clear the area around the fireplace, move furniture back about six feet, and stop burning fires 24 hours before we arrive so the flue is cool. Move lightweight decor off the mantel; vibration can knock things over. If you have pets, keep them in another room while we're working. We bring everything else: drop cloths, HEPA filtration, ladders, brushes, and a camera. If your home is in a Chino Hills neighborhood with an HOA that restricts roof access, let us know when you book.

We install caps from Olympia Chimney and Famco most often because their stainless steel holds up well to the dry heat and occasional heavy rain Chino Hills gets in winter. The right cap keeps rain, birds, and embers out while maintaining proper draft. A galvanized cap from the hardware store will rust through within a few seasons here. We'll measure your flue opening, check the crown condition, and recommend a cap that fits correctly instead of a universal clamp-on that blows off in a Santa Ana wind.

Yes, a damper that won't open or won't seal is one of the most common issues we fix in Chino Hills. Older cast-iron dampers warp and rust, especially in homes where the fireplace sat unused for years. We replace them with top-sealing dampers from brands like Copperfield, which actually seal better than original throat dampers and cut down on the draft that pulls heated air out of your house all winter. If your current damper just needs adjustment or lubrication, we'll do that for a lower cost.

When a liner is genuinely needed, we work with DuraFlex and Olympia Chimney stainless steel systems because they carry the UL listings required by code and they hold up to the heat cycling common in Chino Hills wood-burning fireplaces. The brand matters less than the installation, honestly. A properly sized and insulated liner from any reputable manufacturer will outperform a premium liner that's sloppily installed. We show you the camera footage of why a liner is needed before quoting anything.

Often you can replace just the cap, but in Chino Hills we frequently see crowns that have cracked from years of sun and temperature swings, and a new cap won't fix a failing crown. The crown is the concrete slab that seals the top of the chimney, and when it cracks, water gets into the brick and ruins it from the inside. We'll assess both during the sweep and tell you if the crown can wait or needs sealing now. A cap on a bad crown is a wasted expense.

Yes, prefab fireplaces are common in newer Chino Hills and Eastvale construction, and they need different care than masonry chimneys. The flue is typically a metal pipe that requires specific brushes, never a wire brush that can scratch the interior. We inspect the refractory panels, check the termination cap, and verify clearances to combustible framing. Prefab units have shorter lifespans than masonry, typically 20 to 30 years, and we'll tell you honestly if yours is nearing replacement.

Every professional working under our name is required to hold the license and insurance their state and local jurisdiction requires. That means liability coverage that protects your Chino Hills home if something goes wrong, and workers' compensation so you're never liable if a tech is injured on your property. We're happy to discuss coverage specifics when you book. Anyone you let work on your roof or inside your flue should be able to show proof without hesitation.

Routine cleaning and most repairs like cap replacement, damper work, and minor crown sealing don't require a permit anywhere in San Bernardino County. Structural rebuilds, relining with a change in flue size, or converting a fireplace to a different fuel type may require permits through the Chino Hills Building & Safety Division. We'll tell you during the inspection if your project crosses into permit territory. We don't cut corners on code requirements, even when it would save time.

The honest answer is that cleaning a chimney is dirty, physically demanding work that requires roof access most Chino Hills homeowners would rather avoid, but the real value is the trained eye. A professional sweep spots cracked flue tiles, deteriorating mortar, improper clearances, and hidden animal entry points that a homeowner with a brush and shop vac will miss. More importantly, the camera inspection gives you proof of the flue's condition. If you insist on DIY, we'll still inspect it for you afterward, no judgment.

A chimney fire is a house fire until proven otherwise. If you have flames shooting from the top of the chimney or hear a roar like a freight train, evacuate and call 911 first. Once the fire department clears the scene, call us at (877) 358-0941 and we'll inspect the flue for structural damage before anyone burns again. Smoke backup without flames usually means a blockage or a draft problem, and we can usually diagnose that during a normal appointment.

We book by appointment during our regular hours, Monday through Friday 7 AM to 7 PM and Sunday 7 AM to 7 PM. In the fall, right before burning season in Chino Hills, our schedule fills fast, and waiting until the first cold snap usually means waiting longer. If you're planning to burn, book your sweep in late summer or early fall. For non-emergency issues like a bad smell or a small animal in the flue, we'll get you scheduled as soon as an opening lines up.

First, creosote accumulates, and creosote is highly flammable. A chimney fire can reach 2,000 degrees and crack flue tiles, warp the damper, and spread to the framing of your Chino Hills home. Second, small blockages from nests or debris send carbon monoxide back into the living space, and that's odorless and deadly. Third, water intrusion through a cracked crown slowly destroys the masonry, turning a $200 sweep into a $5,000 rebuild. The sweep is the cheap part of owning a fireplace.

If you're not satisfied with the cleaning, call us and we'll make it right. That's the guarantee, plain and simple. We don't hide behind fine print, and we don't charge you to come back and re-clean something we missed. The camera inspection at the end of every job is our proof and yours. If you see soot or creosote we should have removed, point it out before we pack up, and we'll address it on the spot. Your fireplace should be ready to burn safely when we leave.

Manufacturer warranties apply to the parts we install. Olympia Chimney, Famco, Copperfield, and DuraFlex all stand behind their products, typically covering manufacturing defects for 10 years to lifetime depending on the product line. Our workmanship is guaranteed too: if a cap we installed blows off in a Santa Ana wind because we didn't secure it properly, we fix it. Installation errors are our responsibility, and we don't argue about who's at fault. The warranty is only as good as the installer, and we stand behind our installation.

A smell after cleaning usually means one of three things: a downdraft pushing air down the flue, rain or humidity reacting with creosote residue in the porous brick, or a dead animal. In Chino Hills, the most common culprit in fall is a downdraft, especially on homes near the hills where wind patterns push air down the chimney. If the smell persists more than a week after your sweep, call us back. We'll investigate the cause, not just mask it. A return visit for this is covered by our satisfaction guarantee.
