Trusted Chimney Repair for Arleta Homeowners

Chimney repair in Arleta typically costs $300 – $2,800 depending on the component, and most repairs are completed same-day or within one visit. The most common repairs we handle are chimney cap replacement, flashing repair, crown repair, and liner installation.

Chimney Cap Installation

Chimney Cap Installation means fitting a new protective lid over the flue opening, and it’s the single most effective way to keep rain, birds, and debris out of the chimney. In Arleta, where winters are mild but spring winds can carry seed pods and leaves, an open flue turns into a nesting site or a water entry point fast. We install caps from Copperfield and other professional-grade suppliers, sized to the flue and secured so wind can’t lift them. A typical cap installation here runs $180 – $450 including materials and labor.

What we install

A proper cap does more than sit on top. We use stainless steel or copper caps with a screen mesh that keeps animals out without choking off draft. If your flue has an unusual size, we measure and order to fit rather than bending something generic over it.

When it’s time

If you can see daylight through a missing or damaged cap, or birds have gotten in, the flue is unprotected and acting like a rain catch. In a valley climate like Arleta’s, even a damp flue lining will speed up deterioration and smell musty inside the house.

Chimney Cap Replacement

Chimney Cap Replacement is what you need when the existing cap is rusted, bent, blown off, or otherwise no longer protecting the flue, and it usually costs $220 – $480 in Arleta depending on flue size and material. A worn cap lets rain straight down the flue, which mixes with creosote and turns into an acidic slurry that eats at the liner and masonry. We remove the old cap, inspect the flue opening for damage, and install a correctly sized replacement using Copperfield or Gelco components. If the chase cover underneath is failing, we’ll tell you before we just set a new cap over it.

Rusted caps

Rust isn’t cosmetic. A rusted-through cap means water has been sitting on metal and dripping into the flue for months. We see this often in older Arleta homes where the original cap outlasted its galvanized coating years ago.

Wind damage

High winds in the valley can lift a poorly secured cap. The replacement gets a mechanical fastener, not a friction fit, so it doesn’t end up in the neighbor’s yard the next time wind comes through Van Nuys.

Chimney Liner Installation

Chimney Liner Installation puts a continuous, professionally rated liner inside the flue to contain heat and combustion gases, and for an Arleta home this work typically runs $1,400 – $2,800 installed. A cracked or missing liner is a direct risk: gases can seep into wall cavities, and heat can reach the wood framing around the flue. We install DuraFlex stainless steel liner systems, UL-listed for both masonry and prefab chimneys, sized to the appliance and vented correctly. This isn’t a patch; it’s a structural rebuild of the exhaust path.

When a liner is required

If your home inspector flagged the flue, or a camera inspection shows gaps between tiles, the liner is doing less than it should. Older chimneys in Pacoima and Arleta often have clay tiles that looked fine from the top but separated halfway down.

How we verify the need

We camera-scan before recommending liner work. You get to see the video. If the flue is sound, we’ll say so, and the estimate stays limited to whatever else needs attention.

Chimney Flashing Repair

Chimney Flashing Repair seals the joint where the chimney meets the roofline, and in Arleta it typically costs $350 – $900 depending on access and the condition of surrounding materials. Flashing failures are the leading cause of water stains around the chimney chase and ceiling, and a valley home sees enough seasonal rain for a small gap to do real damage. We remove deteriorating sealant and rusted flashing, inspect the underlayment, and reseal or replace the flashing using step flashing and a weather-rated sealant. The goal is a dry attic and a chimney that doesn’t stain the ceiling below.

Leaks around the roofline

Water running down the outside of the chimney doesn’t always come from the cap. A lifted flashing edge catches runoff and channels it under the shingles. If you see moisture around the chimney after a good rain, that’s the signal to check.

When flashing fails

Years of sun exposure dry out sealant and break the bond between metal and masonry. Arleta’s summer heat ages that sealant faster than people expect. Once it’s cracked, the only fix is removal and a clean reapplication.

Chimney Crown Repair

Chimney Crown Repair addresses the concrete or mortar slab on top of the chimney that sheds water away from the flue, and the usual cost in Arleta is $450 – $1,200. A cracked crown lets water soak into the brick below and degrade it from the inside out, which is how a minor top repair turns into a full rebuild. We remove loose material, fill cracks with a crown-coat system, and when needed, recast the crown with a proper slope and an expansion joint at the flue. That joint matters: without it, thermal movement cracks the crown again in a few years.

Cracked or spalling crowns

Hairline cracks are an early warning. They widen with every hot-cold cycle, and in Arleta’s warm climate, that cycle runs on a fast loop during winter burning season. By the time pieces flake off, water has been entering the masonry for a while.

Precast vs. poured

Most older crowns around Arleta were slathered on flat, which is wrong. A correct crown has a slight slope and an overhang to drip water away from the chimney face. We pour to spec, not to match what was already failing.

Chimney Repair Companies

Chimney Repair Companies in the Arleta area range from one-man sweep outfits to full-service contractors, and the difference matters when the repair goes beyond brushing the flue. You want a company that installs and repairs using brand-name materials, gives you camera evidence for any big recommendation, and stands behind the work. We clean, inspect, and repair under one roof, which means you’re not getting passed off to a subcontractor for the liner or the crown. Harold Lawson runs Chimney Sweep Arleta with that approach: show the homeowner the problem, name the material, and fix it correctly.

What separates one company from another

The single biggest gap is whether the company can actually install what they recommend. We stock and install DuraFlex liners, apply HeatShield resurfacing, and work with Copperfield and Gelco components, so a repair recommendation is backed by the ability to do the work. Many sweep-only companies can’t say that.

Questions to ask any repair company

Ask what material they plan to put in, whether they camera-scan before recommending a liner, and whether the estimate includes cleanup. If they won’t show you the damage, treat that as a red flag, wherever you are in the valley.

Chimney Masonry Repair

Chimney Masonry Repair covers the brick, mortar, and stonework of the chimney itself, and the cost in Arleta depends heavily on scope: tuckpointing a small area runs $500 – $1,200, while rebuilding a leaning or badly spalled chimney can pass $2,800. The masonry is the structure, and when it starts to soften or shift, the entire system loses integrity. We repoint crumbling mortar joints, replace loose bricks, and if the flue interior has thinned, we’ll recommend HeatShield resurfacing instead of jumping straight to a full rebuild. You get an honest recommendation based on what the brick and the camera show.

Spalling brick

Spalling is when the face of the brick pops off and crumbles away. It means moisture has gotten inside and is expanding and contracting, pushing the surface apart. In Arleta’s dry heat, spalled brick won’t heal itself; it only gets worse.

Mortar joints that crumble

Old mortar turns to sand over time. You can test it with your finger in many cases. If the joints are eroding, water gets behind the brick and works on the structure every time it rains. Repointing puts solid mortar back and keeps the wall whole.

Brands We Service

We work with HeatShield resurfacing on a regular basis, and we know where that system performs best: mid-stage flue deterioration that hasn’t yet compromised the full structure. Applying HeatShield means building a ceramic coating inside the existing flue rather than tearing out masonry. It’s a real repair method that returns a smooth, insulated surface to the flue, and it’s one of the reasons we can often save a chimney that another company would write off.

DuraFlex liners and Copperfield components are our standard for installs and cap work. DuraFlex gives us a UL-listed stainless liner that fits both masonry and prefab fireplaces, and Copperfield supplies the caps and chase covers that hold up in a valley climate. Whether you have one of these brands already or any other make, we can help.

Signs You Need a Pro Right Now

• Water inside the firebox. Dampness or puddles after rain mean the cap, crown, or flashing has failed. Each rain event pushes more water into the masonry, and the repair cost climbs as the water works deeper.
• Crumbling brick on the chimney face. That’s spalling, a sign water has been inside the brick for a season or more. It doesn’t stop on its own; it spreads.
• Pieces of clay tile at the bottom of the flue. When a flue tile breaks and falls, the chimney has lost its exhaust path in that section. Gases can reach places they shouldn’t.
• White staining on the masonry. Efflorescence means water is passing through the wall and leaving salt deposits behind. It’s the visible record of a hidden moisture problem.
• A metallic or musty smell around the fireplace. A musty chimney smell often points to a failing liner or a water-soaked flue. If it smells like a basement, something inside the chase is wet and shouldn’t be.

Our Process, Step by Step

1. 1
   Site inspection. We start at the top: cap, crown, flashing, and then down the flue with a camera. The scan shows the actual flue interior, so you see the condition for yourself before any repair is recommended.
2. 2
   Written estimate. The estimate lists the repair, the material, and the price. No vague line items, no upsell into work the camera didn’t show. The written estimate sets the final price and it’s free.
3. 3
   Preparation and protection. We seal off the work area and lay protection inside the home when accessing the firebox. Masonry dust and soot stay contained.
4. 4
   The repair. We use the product that matches the job: HeatShield for the flue interior, DuraFlex for a liner, Copperfield for caps and chase covers, and a proper crown coat for the top slab. The work is done to code and to manufacturer spec.
5. 5
   Final check and cleanup. We leave the site clean, walk you through what was done, and show you the finished work. You get the photo report and the camera images from before and after.
