Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Van Nuys Residents Choose Us for HeatShield Service
HeatShield’s Cerfractory flue sealant behaves differently in Van Nuys than it does in, say, a chilly Minnesota chimney that burns wood every weekend from October to March. Here, the product sits in a flue that might see three fires a year. The failure modes are different. Cracking at the smoke chamber shoulder. Delamination from flue tiles after minor tremors. CrownCoat peeling at the edges from UV exposure. We’ve seen all of it, repeatedly, on Van Nuys chimneys ranging from 1920s bungalows north of Victory Boulevard to mid-century tract homes near Van Nuys Airport.
Cory Mitchell, our owner and lead chimney technician, grew up in Los Angeles and learned combustion safety and venting systems at Los Angeles Trade-Technical College. He’s spent the better part of two decades on rooftops across the West San Fernando Valley, and he’s the first to tell you that Van Nuys service area chimneys have their own personality. When we work on HeatShield systems here, we’re not following a generic service script. We’re applying what we’ve learned from hundreds of local inspections. Every job includes a written price before work starts, a written guarantee on every repair, and a free second visit if that repair fails within 365 days. That’s the 365-Day Done Right Promise, and it applies to every HeatShield job we do.

Common HeatShield Chimney Cleaning Problems We Solve in Van Nuys
- Cerfractory flue sealant delaminating from flue tiles. Van Nuys sits in active seismic territory, and even minor tremors create micro-movements in unreinforced masonry. Over time, HeatShield’s Cerfractory sealant can lose its bond with the underlying clay tile. We find this most often in pre-war bungalows in the southern part of Van Nuys, where original chimneys carry decades of subtle shifting.
- Joint sealant cracking at the smoke chamber shoulder. Older masonry chimneys settle unevenly, and the shoulder where the smoke chamber meets the flue is a stress point. We’ve seen HeatShield joint sealant crack right at that transition on homes built in the 1940s and 1950s. A Level 2 camera inspection shows the crack clearly before we touch anything.
- CrownCoat membrane peeling at crown edges. Van Nuys gets hot, dry summers followed by occasional winter rain. That infrequent wet-dry cycle, combined with strong UV exposure, causes HeatShield CrownCoat to peel away from the crown’s outer edges. It’s a slow process, but once water gets underneath, the damage accelerates.
- Repair mortar spalling over moisture-saturated clay tile. In Van Nuys, many chimneys haven’t been used in decades. That sounds harmless, but disused flues absorb ambient moisture. Applying HeatShield repair mortar over that spongy substrate leads to spalling, the mortar flakes off in chunks. We address the moisture issue first.
- HeatShield sealant cracking after minor seismic events. This is the big one in Van Nuys. A magnitude 3.5 or 4.0 tremor that most people barely notice can still shift a 1920s chimney enough to crack HeatShield sealant. The crack is usually hairline, but it compromises the flue’s integrity. Rooftop inspection after an earthquake is one of the most common reasons we get called in this neighborhood.
HeatShield Service in Van Nuys: What Local Conditions Mean for Your Equipment
Here’s what makes Van Nuys genuinely different from Woodland Hills or Encino when it comes to HeatShield maintenance. The single biggest driver of HeatShield chimney work in Van Nuys is not creosote. It’s the recurrence of minor seismic events. Van Nuys sits closer to the Northridge fault zone than its western neighbors, and the housing stock skews older, with more unreinforced masonry chimneys from the 1920s through the 1950s. When the ground shifts, even slightly, those chimneys flex. HeatShield sealant, for all its strength, is not designed to stretch indefinitely. Hairline cracks form at the smoke chamber shoulder, where structural stress concentrates. You won’t find this problem at the same rate in Woodland Hills or Encino because those areas have different underlying geology and fewer pre-war chimneys. In Van Nuys, if you hear about a small earthquake on the news and you have a masonry chimney with HeatShield sealant, the smart move is a rooftop inspection within a few weeks. Catching a hairline crack early means a straightforward HeatShield Joint Repair System application. Waiting a year means water intrusion, freeze-thaw expansion, and potentially a much bigger repair.
HeatShield Models & Products We Service in Van Nuys
We work with the full HeatShield product line: Cerfractory Flue Sealant, the Joint Repair System, the Smoke Chamber Repair System, and CrownCoat. When your existing system needs a like-for-like repair, we use genuine HeatShield products. Mixing aftermarket sealants with HeatShield’s Cerfractory chemistry compromises adhesion, and we won’t do that to save a few dollars. Most core HeatShield materials are stocked locally, so turnaround on standard Van Nuys Chimney Repair jobs is usually a matter of days, not weeks. For partial rebuilds, we’re honest about when patching makes sense and when you need full reapplication. If the damage extends beyond two adjacent flue tiles, a full HeatShield reapplication is the right call. Patching that kind of damage just creates a new failure point a few years down the road.

AfterHeatShield Service Pricing in Van Nuys
HeatShield chimney cleaning and inspection in Van Nuys typically runs $180 to $340, depending on chimney height, accessibility, and the condition of the existing flue. A Level 2 camera inspection, which we recommend for any HeatShield system that hasn’t been looked at in a while, adds to that range. HeatShield repair work, like Joint Repair System application or CrownCoat sealing, is quoted separately based on what the camera shows. The free estimate we provide includes a written price before any work starts, and that price doesn’t change once the technician is on the roof. If you want an exact number for your Van Nuys chimney, call (559) 249-1347 and we’ll get you scheduled.

FAQs – HeatShield Chimney Cleaning in Van Nuys
Yes, in most cases. HeatShield’s Smoke Chamber Repair System is specifically designed to seal and reinforce cracked smoke chambers without removing the original masonry. The key is catching the crack before it widens and compromises the surrounding structure. We run a Level 2 camera inspection first, and if the crack is stable, a HeatShield application solves it. If the masonry has shifted significantly, we’ll tell you honestly. Call (559) 249-1347 and we’ll show you the camera footage before recommending anything.
HeatShield holds up well to typical Van Nuys seismic activity, but it’s not indestructible. A well-applied HeatShield system will survive years of minor tremors without issue. The problems start when a chimney has pre-existing structural stress, like a settled smoke chamber or deteriorating crown. That’s when a small earthquake turns into a crack. We don’t recommend reapplying after every tremor. We recommend an inspection after any earthquake you actually feel, especially on pre-1950 masonry chimneys. The inspection tells you whether the sealant is still bonded or needs attention.
It’s common, though not ideal. Van Nuys’s long, hot summers with intense UV exposure, followed by intermittent winter rain, create exactly the conditions that cause CrownCoat to peel at the edges. The membrane expands and contracts through dry-wet cycles, and the edges are the first place the bond breaks. Once peeling starts, water gets underneath and accelerates the process. The fix is edge resealing followed by a full CrownCoat reapplication if the peeling is widespread. Ignoring it leads to crown deterioration and, eventually, water in the flue.
HeatShield can be applied to gas fireplace flues, but the decision depends on the flue’s condition and the specific gas appliance. Most Van Nuys homes built after 1960 don’t have wood-burning fireplaces at all, so gas flue work is actually the more common application here. The sealant protects against carbon monoxide leakage through cracked flue tiles, which is a safety issue regardless of fuel type. We’ll need to inspect the flue and the appliance venting setup to determine whether HeatShield is the right product for your system. Call (559) 249-1347 for an assessment.
On a properly prepared surface, a HeatShield repair on an unused Van Nuys chimney can last 15 to 20 years or more. The catch is that “properly prepared” matters a lot on chimneys that have sat dormant for decades. Those flues absorb ambient moisture, and applying HeatShield over moisture-saturated clay tile leads to adhesion failure within a few years. We take the time to dry and prep the substrate before applying any HeatShield product. That prep work extends the life of the repair significantly. For an exact assessment of your unused chimney, call (559) 249-1347 and we’ll put a camera up there.
