Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in North Hills, CA
Chimney repair in North Hills usually falls into one of two categories: cracked clay flue tiles from decades of Valley temperature swings, or water damage at the crown and flashing. Most of the neighborhood’s homes went up between 1950 and 1965, and many still have their original masonry chimneys. Those chimneys have cycled through sixty hot summers and sixty cool, damp winters, and the flue liners inside them are the weak point. Mantel Chimney Sweep handles the full repair scope, from HeatShield flue restoration to complete DuraFlex liner replacements. If you’re seeing spalling brick, water stains on the ceiling near the chimney, or bits of flue tile in the firebox, call (844) 821-5749 for an assessment.
Why North Hills Homes Are Different
North Hills sits in the San Fernando Valley with the Sepulveda Basin a mile away, and that location shapes what we find inside chimneys here. The neighborhood’s 1950s and 60s tract homes were mostly built with original brick fireplaces and masonry chimneys. Some have been remodeled, but a large share still run the original clay flue tile liners those homes shipped with. Clay tile doesn’t fail gracefully. After decades of hot-cold cycling, the tiles crack vertically, and once they crack, heat and combustion gases find their way into the chimney cavity where they don’t belong.
The Sepulveda Basin adds a second layer. Sycamore leaves, cottonwood silk, and windborne pollen blow into chimney caps and screens through the dry months. Then Santa Ana winds arrive and pack that debris in tighter. The first cold snap after a Santa Ana event is when we see the biggest spike in service calls. Homeowners light a fire, the chimney doesn’t draft, and smoke rolls back into the living room. In the homes off Roscoe and Woodley, the combination of a cracked liner and a debris-loaded cap is common enough that we look for both on every North Hills job.
There’s also a winter inversion layer that keeps wood smoke low over the Valley. A properly drafting chimney with an intact liner matters more here than in a hillside neighborhood where the air moves out faster. If your chimney isn’t venting cleanly, you’re not just losing heat. You’re pulling combustion byproducts back into the house.

Our Main North Hills Services
Most North Hills homeowners call us for one of two things: a chimney that hasn’t been cleaned in years, or a dryer vent that’s quietly become a fire hazard. Both are problems we solve in a single visit.
Chimney Sweep in North Hills
A chimney sweep in North Hills is more than knocking soot off the walls. The Valley’s dry summers bake creosote until it’s brittle, and then winter fires add fresh, sticky deposits on top. We remove both layers, check the flue for hidden cracking, and confirm the cap and screen are doing their job against basin debris. Our Chimney Sweep in North Hills page covers what the full service includes, what it costs, and how to know when you’re overdue. A clean sweep is the baseline. The inspection that comes with it is where the real value lives.
Dryer Vent Cleaning in North Hills
Dryer vents in North Hills collect the same fine dust and lint that settles on every flat surface in the Valley, plus whatever the Santa Anas push through the exterior vent hood. A restricted vent makes the dryer run hotter and longer, and lint is exactly as flammable as it sounds. We run professional-grade brushes the full length of the duct and confirm airflow at the exterior termination. Our Dryer Vent Cleaning in North Hills page breaks down the service and typical pricing. It’s one of the most straightforward fire-prevention steps a homeowner can take.

Chimney Repair in North Hills
Chimney repair in North Hills is what we do most, because the housing stock here is old enough that the original masonry components are all reaching end of life together. When a cracked liner or a failing crown gets ignored, the repair bill doesn’t shrink. It grows. Water keeps working its way into the mortar, freeze-thaw cycles do their damage on damp Valley winter nights, and what started as a $300 crown patch becomes a $4,000 liner replacement plus masonry rebuild. We repair what others can only report, and we’d rather catch the problem at the first stage. If you’re unsure whether your chimney actually needs work, that’s what our Chimney Repair service is for: a straight diagnosis with camera evidence, and a clear recommendation on what’s urgent and what can wait.
Chimney Cap Installation
Signs you need it
Debris from sycamores and cottonwoods around the Sepulveda Basin keeps ending up in your firebox, or you hear birds and animals inside the flue.
What it costs in North Hills
Chimney cap installation in North Hills typically runs $240 to $450 depending on the flue size and whether a custom bracket is needed.
How we do it
We measure the flue, select a stainless steel or copper cap sized for your chimney, secure it to the flue tile or crown, and confirm the mesh spacing keeps embers in and debris out.
Chimney Cap Replacement
Signs you need it
Your existing cap is rusted through, the mesh is torn, or a storm has bent it far enough to block part of the flue opening.
What it costs in North Hills
Replacing an old or damaged chimney cap in North Hills falls in the same $240 to $450 range, plus any masonry work if the old cap pulled its anchor bolts loose.
How we do it
We remove the failed cap, check the flue tile underneath for damage, and install a replacement that fits the existing opening without gaps.
Chimney Liner Installation
Signs you need it
Your clay tile liner has cracked from sixty years of Valley thermal cycling, and you’re finding tile fragments in the firebox or seeing smoke stains bleeding through the chimney chase.
What it costs in North Hills
Full chimney liner installation in North Hills using a DuraFlex flexible stainless system typically runs $4,000 to $7,000 depending on flue length and access.
How we do it
We run a camera through the existing flue, size the liner to the appliance, pull the flexible stainless steel liner down the chimney, and insulate and cap it for proper draft.
Chimney Flashing Repair
Signs you need it
You have brown water stains on the ceiling near the chimney, peeling paint on the wall beside the hearth, or dampness in the attic after rain.
What it costs in North Hills
Chimney flashing repair in North Hills typically ranges from $350 to $800 depending on how much of the old flashing must be cut out and replaced.
How we do it
We remove the failed flashing, install new step and counter flashing with proper overlap, and seal the junction so water sheds away from the roofline.
Chimney Crown Repair
Signs you need it
The concrete crown on top of your chimney is cracked, spalling, or has visible gaps where it meets the flue tile, letting water into the masonry below.
What it costs in North Hills
Chimney crown repair in North Hills typically runs $300 to $600 for a resurfacing job, with full crown rebuilds reaching $900 to $1,500 when the old concrete is too far gone.
How we do it
We clean the failed surface, fill cracks with a flexible crown sealant, or form and pour a new crown with a proper drip edge that sheds water away from the chimney body.
What Chimney Repair Costs in North Hills
| Item | Typical range in North Hills |
|---|---|
| Chimney crown repair | $300 – $1,500 |
| Chimney cap installation or replacement | $240 – $450 |
| Chimney flashing repair | $350 – $800 |
| Full chimney liner installation | $4,000 – $7,000 |
Do I really need a new liner, or can it be patched?
That depends on what the camera shows. Minor surface cracking in a clay tile liner can often be restored with HeatShield, a cerfractory sealant that fills and coats the flue walls. If the tiles have shifted, separated, or crumbled, a patch won’t hold, and a DuraFlex stainless liner is the correct fix. Call (844) 821-5749 and we’ll show you the footage so you can see exactly what we’re seeing.
Can chimney repair in North Hills wait until next season?
Some of it can. A rusted cap on a rarely used fireplace isn’t urgent. But a cracked liner or a leaking flashing gets worse every winter, and the difference in repair cost by next year can be substantial. If you’re not sure how urgent your issue is, call (844) 821-5749 and we’ll give you a straight answer without pushing what you don’t need yet.

What North Hills Customers Say
