Trusted Chimney Repair for Universal City Homeowners
Chimney repair in Universal City is work you only want done once. The hillside homes here have specific pressure on their masonry and flue systems: hot, dry summers contract materials, then winter rains drive water into every crack. When a flue liner fails or a crown starts spalling, the fix isn’t a patch job. It’s about getting the right material inside the chimney and keeping combustion gases moving where they belong. Causeway Chimney Sweep handles that from diagnosis through repair, using the same professional lines specified by industry trade associations, not whatever is on the shelf at the hardware store. Noel Carrasco leads our repair work. If you’ve got water stains, crumbling mortar, or a chimney that hasn’t been inspected in years, call (877) 500-2276 for an honest assessment.

Chimney Cap Installation
Chimney Cap Installation is the single most effective way to keep rain, birds, rodents, and debris out of your flue before they become expensive problems. A properly fitted stainless steel cap also arrests sparks, which matters in Universal City’s dry fire season. We install caps from Olympia Chimney and Gelco, brands that hold up to heat and weather far longer than painted sheet-metal options. Installation cost for a standard single-flue cap in Universal City typically runs $300 – $550, with custom caps or chase covers higher depending on flue dimensions and roof access.
Why a cap matters structurally
A chimney without a cap acts like a drain. Rain water pools at the flue edge, accelerates mortar breakdown inside the flue, and shortens liner life by years. We routinely open chimneys in Universal City to find nests, leaves, and tennis balls, all of which trap moisture and block draft on the very first cold night of the season.
What we inspect first
Before we install a cap, we check the flue and the crown. If the crown is cracked, a cap alone won’t stop water intrusion. That’s the difference between a sweep company that slaps something on and one that verifies the repair works.
Styles & brands we work with





Chimney Cap Replacement
Chimney Cap Replacement is usually needed when a cap has rusted through, blown off in a wind event, or was never sized correctly for the flue to begin with. Universal City’s Santa Ana winds are rough on lightweight caps, and a flapping cap can damage the flue tile. We replace caps with professional-grade stainless steel or copper units from Olympia Chimney and Copperfield, sized to the flue and secured with hardware that won’t back out. A replacement cap with standard flue specification runs $250 – $500 in Universal City including removal of the old unit.
Signs the old cap has failed
Visible rust, water streaks down the chimney chase, or a cap that simply isn’t there after a windstorm all point to replacement. If you hear animal sounds from the firebox or smell something musty on humid days, the cap has already failed its purpose.
Replacement with better materials
When we replace, we typically move customers into a 316-grade stainless or solid copper cap. These run slightly more up front but handle the temperature swings and salt air from the coast path toward Universal City far better than zinc-plated steel.
Chimney Liner Installation
Chimney Liner Installation is the repair that separates cleaning companies from full-service chimney specialists. The liner is the actual exhaust path inside your chimney. When it cracks, delaminates, or degrades, combustion gases can seep into wall cavities and living spaces. For relines, we use DuraFlex flexible stainless steel liner systems, the same line specified by certified sweep associations. A full chimney liner installation in Universal City generally runs $2,800 – $6,500 depending on length, diameter, and whether an existing liner needs to be removed first.
When a liner is required
If you’ve switched from wood to a high-efficiency gas appliance, your old terra cotta liner may be too large or too fragile to draft properly. The result is condensation, acid buildup, and eventual masonry deterioration. A correctly sized DuraFlex liner resolves that and meets current flue sizing codes.
The HeatShield alternative
For chimneys where the existing clay liner is largely intact but showing surface cracks, we sometimes use the HeatShield resurfacing system instead of a full liner. HeatShield is a ceramic coating applied inside the flue that restores a seamless, fireproof surface. We’re one of the few Universal City repair companies trained to apply it.
Chimney Flashing Repair
Chimney Flashing Repair addresses the most common source of roof leaks around a chimney. Flashing is the metal system that seals the joint where your chimney passes through the roofline. When it fails, water travels behind siding, rots roof decking, and stains ceilings on the floor below. We fabricate and install step flashing, counter flashing, and apron flashing using professional-grade materials, often with Copperfield copper or coated aluminum depending on the roof. A typical flashing repair around a single chimney in Universal City runs $450 – $1,200 depending on the amount of flashing that needs replacing and the roof pitch.
Why flashing fails silently
Flashing fails long before you see a watermark. The sealant breaks down, metal lifts, and water wicks underneath gradually. By the time a stain appears on the ceiling, the repair has gone from replacing flashing to tear-out and decking replacement. That’s a much more expensive conversation.
What we replace versus reseal for
Sealant alone is a temporary solution. If the metal is intact but lifting, we can re-secure and seal it properly. If there’s rust-through, exfoliation, or the flashing was never stepped correctly, we replace the entire system. We never stretch a roof sealant where a water barrier belongs.
Chimney Crown Repair
Chimney Crown Repair fixes the cement cap that sits on top of the chimney and keeps water out of the masonry itself. A cracked, eroded, or incorrectly poured crown lets water seep straight into the brickwork and flue. Universal City’s freeze-thaw cycles, even though mild, are enough to open existing hairline cracks further. We rebuild crowns using proper crown form, overhang, and drip edge, then seal with a breathable crown coat. Standard chimney crown repair in Universal City runs $800 – $2,000 depending on crown size and whether repointing of the top few brick courses is needed.
What a proper crown must have
A crown should overhang the chimney by at least two inches and carry a drip edge underneath. Most original Universal City crowns were poured flush with the brick, which is why they crack at the corners first. We correct that geometry when we rebuild, so the repair lasts decades.
Sealing versus rebuilding
Hairline cracks can sometimes be handled with a flexible crown sealant. Spalling, missing chunks, or a crown that’s delaminated from the brick means a full rebuild. We’ll show you what we’re seeing before recommending which path to take.
Chimney Repair Companies
Chimney Repair Companies in Universal City fall into two camps: sweeping companies that repair what they can reach and general contractors who build the chimney structure but don’t understand venting. For our Chimney Repair in Studio City neighbors, we bring the same specialist approach. Causeway Chimney Sweep sits in the middle. We’re a specialist that handles the full repair arc from flue to crown, using materials specified by the chimney supply trade. Because we handle sweeping, repair, and dryer vent cleaning in one company, you’re not coordinating three different contractors to get one system back to working order. Call (877) 500-2276 and you’ll get a direct answer about what you actually need.
How to compare repair companies
Look for what materials a company specifies. Companies that install DuraFlex and HeatShield are working with the same product lines certified chimney professionals use. Companies quoting only labor without naming products are often pricing against the cheapest available material. That’s a shorter-lived repair.

What “full service” actually means
Full service means the repair tech who opens your flue can also reline it if needed, resurface it with HeatShield, and correct the flashing on the roof. Most Universal City sweeps refer that work out. We do it in-house, which means the problem you pay to diagnose is the same problem we’re equipped to solve.
Chimney Masonry Repair
Chimney Masonry Repair covers the brick, block, and mortar work that makes up the chimney structure itself: cracked bricks, eroded mortar joints, spalled faces, and leaning chimneys. In Universal City, we see mortar erosion accelerate on older hillside homes where wind and rain hit the chimney on one consistent face. Masonry repair ranges widely. Repointing a few courses of brick runs $700 – $1,800; rebuilding a firebox or a top section of chimney can run $3,000 – $8,000. We only quote after inspection, because what the surface shows rarely matches what’s inside the structure.
Repointing the right way
Repointing is not just filling joints with new mortar. The mix must be softer than the brick itsel, or the brick spalls. We match mortar color and texture and remove failed joints to proper depth before repacking. Done right, it should be hard to tell work was done. Done wrong, you’ll be repointing again in five years.
When repair isn’t enough
If a chimney has significant lean, heavy spalling, or failed internal structure, repair alone won’t hold. We’ll tell you plainly when rebuilding is the safer route. You’ll get a clear recommendation, not a sales push.
Brands We Service
Our chimney repair work depends on the material inside and on top of your chimney, and we specify products by name. DuraFlex is our go-to flexible stainless steel liner for relining jobs. It’s the same liner system specified by certified sweep associations, and we’ve installed it across Universal City chimneys converting to gas and repairing fractured clay liners. We also handle Chimney Repair – North Hollywood homes with the same DuraFlex systems.
HeatShield is the ceramic resurfacing system we apply when a liner is cracked but still structurally viable. Most chimney repair companies in the area don’t carry it because it requires specialized training and application tools. We do. Gelco and Olympia Chimney supply the caps, dampers, and flashings we tighten and install. Whether your home has one of these brands already or we’re specifying new material for your repair, we can get your chimney working again.

AfterSigns You Need a Pro Right Now
- Water streaking down the chimney inside or out. Water intrusion is never cosmetic. It’s moving through your masonry or flashing right now, and every rain event extends the damage zone. On older Universal City hillside homes, this is the last warning before decking and drywall repairs start adding up.
- Large cracks in the firebrick or back wall of the firebox. These open a path for heat to reach surrounding framing. A fire is designed to stay inside the firebox. Cracks mean that boundary has already failed.
- Smoke entering the room instead of drafting up. This is a backdraft sign. A liner may have failed, the flue may be blocked, or the appliance has outgrown the exhaust path. Any of these means the chimney isn’t doing its only job.
- Rust on the damper, cast iron, or firebox components. Rust means water is getting in above and sitting. Where water sits, metal fails, liners corrode, and masonry swells. Rust is always a lead indicator of an issue upstream.
- You hear animal sounds or smell something dead in the chimney. Birds, squirrels, and raccoons in Universal City will nest in flues without caps. Their nesting material is flammable and blocks draft. Even once the animal is out, the nest and debris need full removal.
Our Process, Step by Step
- 1
Inspection and diagnosis. We start with a full visual inspection of the firebox, flue, crown, flashing, and chimney structure. When needed, we run a camera scope up the flue to see liner condition at every point, not just the reachable ends.
- 2
Photo documentation. You get to see what we see. Every recommendation we make is backed by camera images you can look at yourself. Nothing gets recommended that isn’t visible and confirmed.
- 3
Scope of work and honest recommendation. We tell you what’s urgent, what can wait, and what’s optional. You get a flat price for the repair before any work begins. No surprise change orders mid-job.
- 4
Repair with specified materials. We install using the brands we’ve named: DuraFlex liners, HeatShield coatings, Olympia and Gelco caps, Copperfield flashing. You know what’s going into your home. Work is done by us, not subcontracted out.
- 5
Post-repair verification. We test draft, confirm the repair is sealed, and document finished work. Our repairs are covered by our workmanship guarantee, and we leave the site clean. Noel Carrasco follows up personally on larger repair jobs.
How Much Does Chimney Repair Cost in Universal City?
A typical chimney repair in Universal City runs anywhere from $300 for a simple cap replacement to $6,500 for a full stainless steel reline, so how much Chimney Repair costs depends on the scope. Flashing repair usually lands between $450 and $1,200. Crown repair runs $800 to $2,000. Masonry repointing typically costs $700 to $1,800, and firebox rebuilds run higher. Four things drive most price differences: what material failed, how accessible the chimney is from the roof slope, what’s inside the existing flue, and whether water damage has expanded the repair zone.
The easiest way to avoid overpaying is to avoid paying twice. Cheap caps and sealant patches fail in a few years. A repair done with DuraFlex, HeatShield, Copperfield, or Gelco materials lasts decades. We quote flat, and we include camera documentation in every estimate. That’s the free part. You see the problem, you see the scope, and the price will not move unless the wall opens up and shows something the camera couldn’t reach.

Frequently Asked Questions About Chimney Repair in Universal City
Chimney repair is any work that restores the structural integrity or exhaust function of a chimney: liner installation, crown repair, flashing replacement, masonry repointing, and cap installation. In a Universal City home, it stops water intrusion and keeps combustion gases moving outside. If the flue path or water barrier is compromised, sweeping alone won’t fix it.
Most repairs take one day on site. Cap installation and flashing repair are typically finished in two to four hours. A full liner installation or crown rebuild often runs four to six hours, and masonry work may require a return trip if multiple courses need curing between applications. We’ll tell you the time frame before we book.
Chimney repair in Universal City ranges from $300 for cap replacement up to $6,500 for a full DuraFlex reline. Most flashing jobs land between $450 and $1,200, and crown repair runs $800 to $2,000. The exact number depends on what failed and how accessible it is. Call (877) 500-2276 for a free estimate with camera documentation.

Yes. Our workmanship is guaranteed, and the materials we install carry manufacturer warranties from brands like DuraFlex, HeatShield, and Copperfield.
