Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across Lennox
A chimney sweep in Lennox typically runs $189 – $289 for a standard open-masonry fireplace, with Level 2 inspections adding $150 – $350 depending on the flue and access. We work throughout the 90304 zip code almost every week, usually within a few days of your call, because Lennox is a short drive from our dispatch hub. Our crews know the narrow lots, the tight side yards, the shallow roof pitches off Hawthorne Boulevard, and the older stucco rentals where flues sit unused for years. If you need a documented sweep before a tenant moves in or a sale closes, call (833) 467-7685 and we’ll get you on the schedule.
Why Ontario Chimney Is Lennox’s Preferred Chimney Sweep Company
The calls we get in Lennox are rarely about heavy winter buildup. They’re about tenant turnover, pre-sale inspections, a smoke smell in a unit that hasn’t been used in three years, or a landlord who needs documentation for a rental portfolio. We’ve swept chimneys off Inglewood Avenue, worked through backyards wedged between El Segundo and Hawthorne, and pulled bird nests out of flues that had been quiet since the 1990s. Homeowners and property managers tell us the same thing: they need a straight answer, not a scare pitch.
That’s the service we run. Our techs arrive with camera equipment as standard, not as an upsell. We show you the footage, we tell you what it means, and we give you options. Al Vickers built Ontario Chimney around one simple idea: a chimney company should be able to clean the flue, fix the crown, install the liner, and document all of it without passing you between three subcontractors. In Lennox, where the housing stock is older and the access is tight, that continuity matters.
Response time to Lennox is usually one to three business days for a sweep. Level 2 inspections, which run a camera through the flue and check the structure from top to bottom, can often be scheduled within the same week. Call (833) 467-7685 and we’ll give you a straight time window.

Chimney Sweep Services in Lennox
Chimney Sweep Services in Lennox cover the full mechanical cleaning of your flue, smoke chamber, damper assembly, and firebox, using rotary brushes sized to your liner, plus a thorough visual inspection of the crown, cap, and accessible masonry. Most Lennox homes need this once a year if the fireplace gets regular use, or before a new tenant moves in, or when a sale contract requires documentation. A standard sweep in Lennox runs $189 – $289, and a Level 1 inspection is included with every sweep we perform.
Level 1 and Level 2 Inspections
A Level 1 inspection is the visual check we do alongside every sweep. A Level 2 inspection goes further: a camera through the flue, roof access when safe, and a written report with photos. In Lennox’s 1940s – 1960s housing stock, Level 2 is the one we recommend before any rental turn or home sale, because it documents the actual condition of the flue liner and the chimney structure.

Creosote and Soot Removal
Most Lennox fireplaces burn wood occasionally, so creosote is usually first-degree and manageable. What we see more often is soot accumulation in flues that vent gas appliances year-round, and we remove that with the same attention we give a wood-burning fireplace. We’ll tell you plainly whether the buildup is a routine clean or a sign of a venting problem.

Annual Sweep and Fireplace Cleaning
Our annual sweep package includes the flue cleaning, firebox cleaning, damper check, and a written condition note for your records. For Lennox landlords managing multiple units, we can schedule several units in one day and provide per-unit documentation that works for property files. That’s the kind of service a rental market like Lennox actually needs.

Chimney Cleaning in Lennox
Chimney Cleaning in Lennox means removing soot, creosote, and debris from a flue that may not have been touched in five, ten, or twenty years. In this part of LA County, fireplaces get used for ambiance on cool evenings, not for heating through a long winter, so the buildup is rarely dramatic. The problem here is neglect: an unused fireplace hides cracked crowns, missing spark arrestors, and bird activity until a new tenant or buyer asks questions. A standard cleaning in Lennox runs $189 – $289.
Pre-Sale and Tenant-Turnover Cleans
This is the Lennox specialty. A seller needs a clean chimney report for escrow. A landlord needs a documented sweep before a new lease. We handle those jobs regularly, and we run the camera before we recommend anything beyond the cleaning. You’ll see the evidence for yourself.
Debris Removal and Bird Blockage
Birds love an unused chimney. We routinely pull nests, feathers, and debris out of Lennox flues, especially in the spring. A missing cap is usually the entry point, and we can replace it with a Famco or Gelco cap that fits the flue and keeps it out permanently.
Trusted Brands We Service in Lennox
We don’t put hardware-store parts on a Lennox chimney. The caps, dampers, and liner components we install come from manufacturers the chimney trade actually specifies: Famco caps and dampers, Gelco components, and Copperfield distribution for professional-grade materials. When we reline a flue, we use DuraFlex flexible stainless steel, because it handles the offset flue runs so common in older Lennox construction. For flues with cracked clay tiles but sound structure, we offer HeatShield ceramic resurfacing as a lower-disruption alternative to full liner replacement. We keep common parts stocked for Lennox jobs, which means fewer return trips and faster turnaround. When you call, we’ll tell you what your chimney actually needs, not what’s easiest to sell.

AfterCommon Chimney Sweep Problems We See in Lennox Homes
- Rental-turnover discoveries: A chimney that sat unused through three tenants suddenly becomes an issue when the fourth tenant reports a smoke smell. The flue has been blocked or the damper rusted shut, and nobody knew because nobody used it. We document it, clean it, and fix what the camera shows.
- Missing spark arrestors and bird nests: Lennox sits under the LAX flight path, and the dry, mild climate invites birds into open flues. A missing spark arrestor is also a fire-safety problem during Santa Ana wind events. We check the cap on every sweep.
- Cracked crowns on 1940s – 1960s masonry: Concrete chimney crowns on older Lennox homes deteriorate after decades of sun and smog exposure. Water gets in, the masonry spalls, and the damage spreads. We’ll show you the cracks before we touch anything.
- Multi-tenant flue confusion: Small apartment buildings in Lennox often share stacks or run appliances into flues never designed for them. When we sweep a multi-unit building, we check each flue’s condition and document which unit vents where. That record matters for liability and for code compliance.

FAQs About Chimney Sweep in Lennox
Yes, and in Lennox specifically, an unused fireplace is often the one most in need of an inspection before a tenant or buyer asks questions. The flue may be blocked by a bird nest, the damper may be rusted shut, or the crown may be cracked in ways you can’t see from the ground. A sweep plus a Level 1 inspection runs $189 – $289, and for rental turnover we recommend a Level 2 camera inspection so you have documented proof of the flue’s condition. Call (833) 467-7685 and we’ll walk you through which level your situation needs.
You’ll see it on the camera footage. That’s the only honest way to tell. We run a camera through the flue during a Level 2 inspection, and if the clay tiles are cracked, spalling, or missing, we’ll show you the video ourselves. Then we’ll give you options: HeatShield ceramic resurfacing if the structure is sound, or a DuraFlex stainless liner if the flue needs a full reline. We won’t recommend either one without the footage, and we’ll tell you plainly if a simple cleaning is all you need.
Shared stacks and undocumented flue venting. In Lennox’s small apartment buildings, multiple units may vent into the same masonry chimney, and after decades of tenant turnover, nobody knows which flue serves which unit. If one flue has a blockage or a cracked liner, it can push combustion gases into a neighboring unit. We document each flue during the sweep, label what we find, and give you a report that works for property files and code compliance. That’s the kind of documentation a Lennox landlord actually needs.
Because Lennox fireplaces rarely burn hot and long through a winter season the way they do in colder climates. The coastal-influenced weather means fireplaces are used for ambiance and occasional cool evenings, which produces light first-degree creosote at most. The real Lennox problem is neglect: long-unused fireplaces, bird-blocked flues, and cracked masonry that goes unnoticed for years. That’s why our Lennox sweeps always include a visual check of the crown and cap, not just the flue.
Yes, and there are a lot of them in Lennox’s 1940s – 1960s subdivisions. Pre-fab flues have their own inspection standards and require care with the rotary brushes so the liner isn’t damaged. We sweep them regularly, check the termination cap and roof clearance, and run the camera when the homeowner or property manager wants documentation. Pricing for a pre-fab sweep in Lennox runs $179 – $249.
