Trusted Chimney Repair for Simi Valley Homeowners
A cracked flue liner or a leaking chimney crown isn’t a cosmetic issue. It’s how chimney fires start and how carbon monoxide finds its way into a home. Chimney repair in Simi Valley is the difference between a fireplace that’s safe to burn and one that’s quietly putting your family at risk. Ray Wilkins leads our crew, and since 2015 we’ve built our reputation on finding problems early and fixing them with professional-grade materials like DuraFlex and HeatShield, not off-the-shelf shortcuts. We answer 24/7, and we dispatch fast from 7am to 7pm, Sunday through Friday. Call (833) 593-4098 when you need a chimney that’s actually safe, not just clean.
Chimney Cap Installation
Chimney Cap Installation keeps rain, embers, birds, and debris out of your flue while your fireplace is doing its job. You need one when your chimney is uncapped, or when the existing cap is rusted through, missing its mesh, or letting water drip down into the firebox. Our team in Simi Valley installs Copperfield and Gelco caps sized to your flue and anchored so they hold in the valley’s occasional Santa Ana gusts. Most cap installations here run $250 to $600 depending on flue size and cap material.
Why an open flue costs you money
An uncapped chimney lets the valley’s dry, dusty air carry grit and leaves into your flue. That debris becomes fuel, and it also blocks proper draft. A simple cap install is cheaper than the repair bill it prevents.
What we install and how
We measure the flue, match the cap to the tile or liner, and secure it with mechanical fasteners, not just friction. The mesh we use keeps spark emissions down, which matters in Simi Valley’s fire-prone seasons.

Chimney Cap Replacement
Chimney Cap Replacement swaps out a cap that’s rusted, warped, or no longer keeping rain and animals out of the flue. You need it when the cap is visibly deteriorated, the mesh is torn, or water stains appear on the ceiling near the fireplace. Chimney Sweep Simi Valley removes the old cap, inspects the flue top, and installs a new Copperfield or Gelco unit sized correctly for your chimney. Expect $300 to $650 for most replacements, depending on cap size and whether the flue tile needs minor repair at the top.
Rust on a cap usually means moisture inside
When we pull a rusted cap in Simi Valley, we often find the crown or flue tile underneath has been taking on water too. That’s exactly why we don’t just swap the cap and walk away. We look at what the failed cap was hiding.
Mesh that keeps both sparks and critters out
A proper replacement cap includes spark-arresting mesh sized for your flue. Without it, a bird will move in and block the draft. With it, you get both fire safety and unobstructed airflow.
Chimney Liner Installation
Chimney Liner Installation places a new stainless steel liner inside your existing flue to contain heat, gases, and creosote. You need one when the clay tiles are cracked, the flue is oversized for your appliance, or a camera inspection shows gaps that vent into the wall cavity. We install DuraFlex liner systems in Simi Valley, sized to your fireplace, insert, or stove and insulated where the chimney runs through unheated space. Liner installation here typically runs $2,000 to $4,500 depending on flue height, access, and whether insulation is required.
Camera inspection before a liner goes in
We don’t line a chimney we haven’t seen from the inside. Our camera scope shows exactly where the old flue failed, and that photo report goes to you before we recommend a liner. Nothing gets sold on guesswork.
DuraFlex means a flue sized right, not just new
A liner has to match the appliance’s BTU output and draft requirements. DuraFlex gives us the flexibility to size and route a liner that pulls correctly. An oversized flue cools the gases too fast and piles up creosote, so the fit is genuinely part of the safety.
Chimney Flashing Repair
Chimney Flashing Repair fixes the metal transition where your chimney meets the roofline, which is the most common source of chimney-related leaks. You need it when water stains appear on the ceiling or walls near the fireplace, or when the flashing is visibly lifted, rusted, or pulling away from the brick. We remove the old flashing, install proper step and counter flashing, and seal the transition with materials that handle Simi Valley’s dry heat and occasional heavy rain. Flashing repairs in this area generally cost $400 to $900 depending on chimney size and roof pitch.
Why flashing fails even when the roof looks fine
The valley’s long dry spells bake caulk and sealant until it shrinks and cracks. Then the first real rain soaks the gap. Flashing that’s properly installed in metal and seated with quality sealant survives those cycles far longer than a caulk patch.
We check the crown while we’re up there
Flashing is rarely the only joint taking on water. When we repair flashing, we also look at the crown, the cap, and the top courses of brick. The goal is to stop the leak at every entry point, not just the most obvious one.
Chimney Crown Repair
Chimney Crown Repair restores the concrete slab that caps the top of your chimney and sheds water away from the flue. You need it when the crown is cracked, spalled, or worn down to the point where water pools instead of draining. Our Simi Valley crew rebuilds crowns with properly mixed mortar, a slight slope to shed water, and an expansion gap so the crown can move without cracking against the flue tile. Crown repair typically runs $600 to $1,200 depending on chimney size and how much of the old crown has to come off.
A cracked crown invites water into your brick
Water that sits in a crown crack soaks into the brick below. Over time, that brick spalls and the chimney starts to shift. A well-sloped, properly cured crown stops water at the top, where it should have stopped all along.
Why we don’t just patch the crack
Patching a crown crack with sealant is a temporary fix. A crown that’s cracked in multiple directions or crumbling at the edges needs a full recast. The patch lasts a season; the recast lasts decades.
Chimney Repair Companies
Chimney Repair Companies in Simi Valley range from sweep-only outfits to full-service operations like ours that actually fix what a cleaning uncovers. You need a company that can go past the sweep when the tech is already there, not one that hands you a report and tells you to call someone else. Chimney Sweep Simi Valley is built around that continuity. Since 2015, Ray Wilkins has run our crews with one rule: if we find a problem during a sweep, we tell you what it is, show you the camera footage, and quote the repair before we leave.
What to ask before hiring a repair company
Ask whether the crew does their own repair work or subcontracts it. Ask whether they scope the flue with a camera before recommending a liner. Ask what materials they use by name. If a company can’t answer those questions, you’re talking to a middleman, not a repair team.
Why sweep-to-repair continuity matters here
Simi Valley homes burn wood seasonally, and creosote hides cracked tiles and failing mortar. A company that only cleans sees half the picture. A company that cleans and repairs sees the whole thing and can act before water or heat makes the problem worse.
Chimney Masonry Repair
Chimney Masonry Repair rebuilds the brick, mortar, and stone that keep your chimney standing straight and sealed against water. You need it when bricks are spalling, mortar joints are crumbling, or the chimney is visibly leaning or bowing. We repoint joints, replace damaged brick, and rebuild sections where the original masonry has failed. Masonry repair in Simi Valley typically runs $500 to $1,800 depending on how much brick has to come out and how tall the chimney is.
Spalled brick is more than an eyesore
When brick faces pop off, they expose the softer inner brick to weather. That accelerates the damage. We cut out the broken brick, match the color and texture as closely as the original, and repoint the surrounding joints so the repair blends in.
Repointing before a full rebuild
Most Simi Valley chimneys don’t need to come down. They need the failed mortar cut out and replaced with a mix that’s compatible with the original brick. That’s repointing, and it’s the most cost-effective masonry repair there is when it’s done before the wall loses its bond.
Brands We Service
We work with Copperfield caps and dampers because they’re built to hold their fit season after season, and we know where they wear out and how to install them so they don’t. Copperfield’s top-sealing dampers are a real energy fix for older chimneys, and we install them with the same care we’d put into a liner.
DuraFlex is our liner system of choice because it handles the sizing and draft requirements of modern inserts and stoves without a fight. HeatShield gives us a resurfacing option for flues where the tile itself is cracked and can’t be relined with steel. Whether you have HeatShield, DuraFlex, Copperfield, or any other make, we can help.

AfterSigns You Need a Pro Right Now
- Water stains on the ceiling or wall near the fireplace. This means water is getting in somewhere around the flashing, crown, or cap. In Simi Valley, where rain comes in heavy bursts between long dry spells, a small leak becomes a mold and rot problem faster than you’d expect.
- A smoky smell inside the house when you’re not burning. That’s not leftover from the last fire. It usually means the flue is blocked or the draft is reversed, which can push carbon monoxide into the living space. This one’s not a wait-and-see.
- Flakes of brick or mortar on the ground next to the chimney. That’s spalling, and it means water has gotten into the brick. Once brick faces start popping off, the damage accelerates every season it’s ignored.
- You see rust streaks on the inside of the firebox. Rust means water is running down the flue, and water plus creosote makes the flue walls deteriorate faster. This is a warning sign that a liner or cap has failed.
- A fire that’s suddenly hard to start or keep lit. Draft problems come from blockages, a wrongly sized liner, or a flue that’s too cold. All three are fixable, and all three are symptoms of a system that isn’t working safely.

How Much Does Chimney Repair Cost in Simi Valley?
What affects the price most is access. A one-story chimney with easy ladder reach is quicker than a two-story chimney with a steep roof pitch. Flue height matters for liners, and chimney width matters for crowns and caps. The type of brick, the condition of the surrounding masonry, and whether we’re repairing one joint or rebuilding a section all move the number.
The best way to avoid overpaying is to get a camera inspection before committing to a liner or a rebuild. If a company quotes you a liner without scoping the flue, they’re guessing. Our estimates are free, and we’ll show you the footage so you know exactly what you’re paying for. Call Chimney Sweep Simi Valley at (833) 593-4098 for a written estimate. We answer 24/7.
