Chimney Cap Installation

Chimney Cap Installation puts a proper weather-tight lid over your flue, and in North Hollywood it’s one of the most cost-effective repairs we do. Without a cap, rain lands directly inside the flue, ash gets wet, and damp creosote turns acidic and eats at the liner. Birds and rodents also build nests in uncapped chimneys, which block draft and can push smoke back into the house. We install Gelco caps and other contractor-specified hardware sized to your flue, not generic covers from a home center. Typical cap installation runs $350 to $750 depending on flue size and roof access.

When a New Cap Makes Sense

A cap should be part of every functional chimney system. If yours is missing, the flue is exposed to every rain event that rolls through the Valley. We install caps on both masonry and factory-built chimneys.

Materials and Fit

The right cap is sized for your flue and installed so it won’t shift in wind. We use durable Gelco components and check that the cap’s mesh is small enough to keep embers in and animals out.

Chimney Cap Replacement

Chimney Cap Replacement is needed when the old cap has rusted through, warped, or pulled loose from the flue. A bent or missing cap lets water pool at the base of the flue, and over time that moisture works its way into the brick and mortar below. In North Hollywood’s mild winters, the damage shows up as staining, musty smells near the fireplace, and deteriorated mortar joints rather than dramatic freeze-thaw cracking. Expect to pay $200 to $500 for a standard replacement, depending on flue size and the condition of the existing crown. We confirm what’s salvageable during the estimate and never recommend work the flue doesn’t need.

Signs the Old Cap Is Done

Rust streaks down the chimney, a cap that’s visibly tilted, or debris inside the firebox all point to cap failure. We’ll assess it as part of a full chimney inspection and show you what we find.

Replacement With an Upgrade

Sometimes a basic cap gets replaced with a multi-flue or custom-fabricated cap for better coverage. We’ll give you a written estimate first, and the price we quote is the price you pay.

Chimney Liner Installation

Chimney Liner Installation restores a safe passage for smoke and combustion gases when the original clay tile liner has cracked or deteriorated. A compromised liner lets heat reach combustible framing and allows carbon monoxide to seep through mortar joints into living space. We install DuraFlex flexible liner systems, a professional-grade product not available at consumer retailers. In North Hollywood, a full stainless liner installation typically runs $1,800 to $4,500 depending on flue height, diameter, and whether the old liner needs to be broken out first. We also offer HeatShield ceramic restorative as a cost-sensitive alternative to full relining when the original liner is still structurally sound.

HeatShield as an Alternative

HeatShield is a ceramic resurfacing system that seals cracked flue tiles without removing the original liner. It’s an option many basic sweep services can’t offer, and it often saves thousands compared to full replacement. We’ll tell you honestly whether your flue qualifies or whether a new liner is safer.

Why DuraFlex

We stock and install DuraFlex liner systems because they’re built for the long haul and spec’d by certified chimney contractors nationwide. The right liner diameter matters for draft, and we size it to your appliance rather than forcing a one-size-fits-all tube in.

Chimney Flashing Repair

Chimney Flashing Repair addresses the metal seal where your chimney meets the roofline, which is where most chimney leaks actually start. Over time, flashing pulls away, corrodes, or was never installed correctly to begin with. Water then travels along the chimney and into the attic or down the interior wall. In North Hollywood, where hillside roofs and valley flat roofs both create odd drainage patterns, we see a lot of flashing that was simply slapped on without proper step flashing underneath. Flashing repair in the area typically costs $500 to $1,200 depending on roof slope and accessibility.

Finding the Real Leak

Not every chimney leak is the flashing. We check the crown, the cap, and the masonry before tearing anything open, then fix what’s actually leaking. You deserve a diagnosis, not a guess.

Roof-Friendly Installation

We cut in new step flashing and counterflashing where it’s needed and reseal with materials meant for your roof type. The work is done from the roof side, and we protect shingles and tiles while we’re up there.

Chimney Crown Repair

Chimney Crown Repair fixes the concrete slab that caps off the top of the chimney structure. A crown that’s cracked, spalled, or was poured too thin lets water enter the chimney chase and work its way down through the brick. Most crowns in North Hollywood were originally built with standard mortar mix, which isn’t meant for that horizontal surface and breaks down within a decade or two. We remove and re-pour crowns with a proper Portland-based mix, sloped away from the flue so water drains off. Crown repair here generally runs $500 to $1,500 depending on chimney size and how much of the old crown must be removed.

Cracks That Matter

Hairline cracks in a crown are normal, but cracks wider than a credit card are a problem. We’ll tell you when a crown can be sealed and when it needs a full re-pour.

Slope and Overhang

A proper crown should slope away from the flue and overhang the chimney edge. We build crowns that way, because a flat crown with no overhang is just a water collection basin.

Chimney Repair Companies

Chimney Repair Companies in the San Fernando Valley range from one-person sweep operations to full-scale masonry contractors, and they don’t all do the same work. Many only clean and inspect, then hand you a referral when they find damage. Ashford Chimney Sweep is a repair-capable sweep: inspection findings get fixed in the same relationship, not passed off to someone you’ve never met. We work with trade brands like Copperfield, Olympia Chimney, and DuraFlex, which signals a level of parts sourcing you won’t find with a generalist handyman. For most North Hollywood repair work, expect $350 to $4,500 depending on what’s actually wrong with your chimney system.

What to Look For

Ask whether the company repairs what they find, or just reports it. Ask whether they use professional-grade materials or whatever is on the shelf. A repair company should be able to fix the flue, the cap, the crown, and the flashing, not just sweep and refer.

Our Approach

We’re a single-trade contractor focused on the full chimney system: flue, liner, cap, crown, and venting. No generalist dabbling. No inspection report and a wave goodbye. We repair what we find.

Chimney Masonry Repair

Chimney Masonry Repair rebuilds the brick, block, or stone structure of the chimney itself. In North Hollywood’s mild climate, masonry failure usually comes from water absorption over years, not freeze-thaw cycles. You’ll see spalled brick faces on the ground, crumbling mortar joints, or a chimney that’s leaning slightly. We repoint joints with mortar matched to the existing profile, replace damaged brick, and rebuild sections when necessary. Typical masonry repair in this area runs $800 to $2,500, though a full top-to-bottom rebuild costs more. The estimate is always free, and we’ll show you photos of exactly what needs work.

Repointing vs. Rebuilding

Repointing removes deteriorated mortar and replaces it with new, which is appropriate when bricks are still solid. When the brick itself is spalling or the structure has shifted, we’re honest about the need for a rebuild. You can see every problem we see in the camera report.

Matches That Look Right

Nothing looks worse than a patch of bright new mortar on an older chimney. We match the mortar color and joint profile so the repair blends with the home instead of announcing itself.

Brands We Service

We work with DuraFlex flexible liner systems on a regular basis, and we know where they wear and how to install them correctly for your specific flue dimensions. A DuraFlex liner isn’t a one-size-fits-all product, and sizing it wrong kills your draft and your appliance’s performance. We also work extensively with HeatShield ceramic restorative, the industry standard for resurfacing cracked flue tiles without a full reline. We know which flue conditions make a HeatShield application the right call and which ones call for new steel.

Our parts sourcing runs through professional supply channels like Copperfield and Olympia Chimney, which means the hardware we install is what certified contractors across the country trust. Gelco and Famco components round out our cap and venting work. Whether you have a DuraFlex liner, a HeatShield-treated flue, or any other make, we can assess it and repair it properly.

Signs You Need a Pro Right Now

• Smoke backing up into the room. This means the draft has failed, usually from a blocked flue, a damaged liner, or negative air pressure. It’s not something to live with: a blocked flue pushes carbon monoxide into the house.
• Water stains on the ceiling or wall near the chimney. Water is getting past the flashing, crown, or cap, and it’s been doing it for a while. The longer it runs, the more masonry and framing damage it does.
• Crumbling brick or mortar on the ground below the chimney. This is spalling, and it means the masonry has absorbed enough water to start breaking apart. Left alone, the chimney can become structurally unsound.
• A cap that’s missing, tilted, or rusted through. An uncovered flue is an open invitation to rain, animals, and embers. The cap is the cheapest repair with the biggest protective payoff.
• Smell of smoke or damp creosote when the fireplace isn’t lit. That odor means the flue isn’t venting properly, even at rest. It’s a sign to get an inspection before burning season.
