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 Walnut, CA
Chimney repair in Walnut is less about heavy soot and more about decades of idle weather damage: rusted caps, cracked crowns, and factory-built units from the 1970s and 80s that have outlived their weather seals. Most Walnut fireplaces see only a few weeks of use each year, so the real work is inspection and restoration, not aggressive creosote removal. Pilgrim Chimney handles both: we find the problem during a sweep and we fix it, from the firebox up through the spark arrestor. Call (866) 253-5031 when you want a single contractor who can diagnose and resolve the issue on the spot.
Why Walnut Homes Are Different
Walnut is a planned-tract community in the San Gabriel Valley, built mostly between the 1960s and the 1990s. That means single-story ranches and two-story Mediterranean stucco homes with masonry fireplaces sitting on raised hearths, many of them factory-built units or gas inserts rather than full masonry chimneys. The terrain matters too. Homes in the hillside-adjacent streets below the Puente Hills and near the unincorporated county edge sit in hotter, drier, windier conditions than the valley floor. The inland climate brings mild winters and a long dry Santa Ana season, so fireplaces stay cold for most of the year. What accumulates during those idle months is not creosote. It is bird nesting material, leaf debris, rust, and cracked mortar that the dry air and temperature swings slowly pull apart. We also know that many Walnut households prefer to keep the interior untouched during service, so dust-controlled sweep and vacuum methods are standard procedure for us here, not an add-on.
Styles & brands we work with
Our Main Walnut Services
Walnut homeowners call on us for two things most often: the annual safety inspection and cleaning of a fireplace that sees only occasional use, and the dryer vent cleaning that most homes have never had done once.
Chimney Sweep in Walnut
In Walnut, a sweep is rarely about a soot-choked flue. It is about confirming the system is safe to use after ten or eleven idle months, removing the light creosote that does form during a short burning season, and clearing out the bird nests and debris that accumulate under a missing or rusted spark arrestor. We inspect the full path from firebox to cap and give you a straight answer about what needs work now and what can safely wait. See our full Chimney Sweep in Walnut page for step-by-step detail and what to expect from the visit.
Dryer Vent Cleaning in Walnut
Dryer vents in Walnut tract homes are often long runs that exit through the roof or a side wall, and lint accumulates just as fast here as anywhere else in the San Gabriel Valley. When the dryer starts taking two cycles to dry a load or the laundry room heats up, the vent is almost always the cause. We clean the full run from the dryer to the exterior termination and show you what came out. See the Dryer Vent Cleaning in Walnut page for how we handle multi-story vent runs and what the job costs.

Chimney Repair in Walnut
Most chimney repair calls in Walnut start with one of two discoveries: a rusted spark arrestor cap on a factory-built chimney from the 1980s, or a cracked crown on a masonry fireplace that has been absorbing decades of dry heat and Santa Ana wind. These problems do not improve with time. Water gets in, the flue deteriorates further, and what begins as a $300 crown repair turns into a $4,000 liner replacement. Pilgrim Chimney has served Walnut since 2014, and our repair crews carry professional-grade materials from Chimney Repair brands like DuraFlex, HeatShield, and Copperfield, sourced from industry distributors rather than hardware-store patch kits.
Chimney Cap Installation
Signs you need it
Birds or debris falling into the fireplace, visible rust holes in the existing cap, or water staining on the ceiling near the chase are the typical signs in Walnut.
What it costs in Walnut
Chimney cap installation in Walnut typically runs $180 to $575, depending on cap size, material, and whether the old cap must be removed first.
How we do it
We remove the old cap, inspect the flue termination for damage, then install a new cap sized for the flue and secured against Santa Ana wind gusts.
Chimney Crown Repair
Signs you need it
Hairline cracks on the cement crown, crumbling mortar at the top edges, or water running down the exterior masonry after rain all point to crown failure.
What it costs in Walnut
Chimney crown repair in Walnut runs $450 to $900 for a standard repair, while a full crown rebuild falls between $1,100 and $2,550.
How we do it
We grind out the damaged crown surface, apply a professional-grade sealant or recast the crown, and slope the finished surface so water runs away from the flue.
Chimney Flashing Repair
Signs you need it
A damp ceiling or wall near the fireplace after winter rain is the most common sign of failed flashing in Walnut’s sloped Mediterranean-tile roofs.
What it costs in Walnut
Chimney flashing repair in Walnut runs $250 to $800, depending on whether we are sealing a small gap or replacing the full flashing assembly.
How we do it
We lift the surrounding tile or shingle, remove the old flashing, install new step and counter flashing, and seal every seam with heat-rated flashing adhesive.
What Chimney Repair Costs in Walnut
| Item | Typical range in Walnut |
|---|---|
| Chimney cap installation | $180 – $575 |
| Chimney crown repair | $450 – $900 |
| Chimney flashing repair | $250 – $800 |
Do I really need a new chimney liner if the old one is still in place?
A liner can fail from the inside without visible damage from the ground. During an inspection, we run a camera into the flue and show you the footage if deterioration is present. Call (866) 253-5031 to book an inspection and see exactly what we see before any work is quoted.
How often should a fireplace in Walnut be inspected?
Even with light use, we recommend an annual inspection. The dry climate, nesting birds, and long idle stretches cause different problems than heavy burning would. Call (866) 253-5031 and we will schedule a visit that includes the full inspection with the sweep.
Brands We Service in Walnut
We work with professional-trade brands like DuraFlex, HeatShield, and Copperfield because Walnut’s aging factory-built chimneys need components that fit correctly and last. We stock caps, liners, and flashing parts locally, which means fewer return visits and no waiting on a hardware-store order. See our brands for the full list of manufacturers we trust.

What Walnut Customers Say
"Drop cloths everywhere, HEPA vac, and not a speck of soot on the carpet. I'd been dreading the mess for nothing."
— Claudia Delgado"Fireplace had never drawn properly since we moved in. He found the damper was only opening halfway due to a bent linkage and fixed it in ten minutes."
— Cole Thompson"Our tenant called us in a panic on a Friday afternoon, which is the worst possible timing for a property 200 miles away. I called these guys at four, they were on site by six, and they sent me photos and a written summary the same night so I could approve the work without driving down. Tenant said the technician was polite and cleaned up. Invoice came in slightly under the estimate. I have now made them our default for anything in that area."
