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 Pasadena Homeowners Choose Gelco Chimney Cleaning
We provide independent Gelco chimney cleaning, inspection, and repair service in Pasadena, TX.

We’re not affiliated with, authorized by, or endorsed by Gelco, and we don’t sell their products. We’re an independent provider, and our credibility comes from documentation, not a factory badge. Call (833) 334-7488 for a free estimate on any Gelco system in Pasadena.
Why Trust Remington Chimney Sweep for Your Gelco Chimney Cleaning?
Gelco makes chimney caps and the components that top off a metal chimney system, and the technicians who work on them run into the same handful of problems over and over. We’ve built our reputation on knowing those problems and fixing them correctly, not on a factory relationship we don’t have.
Our technicians have up to 14 years of experience, and much of that time has been spent on prefabricated metal chimneys and masonry relining. They know how a snap-lock joint seats, how a storm collar should sit against the casing, and how a flex liner is supposed to hang inside a flue. When we service Gelco equipment, we use quality replacement parts that fit it and we follow the clearances the original system was listed with. That’s what keeps a repair warranty-safe: matching profiles, correct spacing to combustibles, and no improvised parts jammed into a place they don’t belong.
We also document what we find. Photos, camera footage, and a written summary of the flue and cap condition. If you’re buying or selling a Pasadena home, that record matters more than any badge on a van.

Common Gelco Chimney Cleaning Problems We Fix in Pasadena
Pasadena’s climate is hard on metal chimney systems. Long humid stretches, sudden heavy rain, and a short burning season that leaves the chimney sitting idle most of the year all push the same failures. Here are the ones we see most:
- Missing or rusted-out rain caps. A cap that’s gone or rusted through lets water straight into the flue. Over time that water rusts the inner wall from the inside out, and by the time you notice it the damage is often structural. We replace caps with correctly sized assemblies that actually shed water.
- Corroded or loosened snap-lock joints. The joints on a Gelco prefab stack are meant to seat tightly and stay that way. Humidity and thermal cycling work them loose, and a gap at a joint opens clearance-to-combustibles points that were never meant to be exposed. We check every joint and re-seat or replace sections as needed.
- Cracked top plates and storm collars. These are the parts that keep water from tracking down the outer casing. When they crack or pull away, water gets between the flue and the casing, and you end up with staining on the ceiling or rust flakes in the firebox long before you see anything wrong on the roof.
- Displaced or sagging flex liners. In a masonry chimney, a Gelco stainless flex liner that was undersized or poorly installed can sag or shift. That traps creosote in the wrong places and kills your draft. We camera the flue, find the problem, and re-hang or replace the liner correctly.
- Water intrusion from storm-driven rain. Gulf Coast storms push rain sideways, not just straight down. Casing seams, collar edges, and cap skirts all take a beating. Waterproofing the masonry and sealing the metal system properly is the fix.
Gelco Parts & Our Repair-vs-Replace Approach
When a Gelco system is intact and serviceable, we use genuine Gelco replacement components: caps, storm collars, top plates, and matching snap-lock sections. Mixing profiles from different makers compromises clearances and fit, and it’s not worth the small savings. Where the original system has rusted through its inner wall or lost its listed clearances, though, the honest advice is full system replacement, not piecemeal patching. A patch on a compromised flue is money spent on a problem that comes back.
For masonry chimneys, a properly sized listed liner is usually the safer repair, and that’s where our DuraFlex and HeatShield capability comes in. We’ll tell you what your chimney needs, and what it doesn’t. Call (833) 334-7488 and we’ll walk you through the options.
Our Gelco Service Process – Step by Step
- 1
Diagnosis. We start with a Level 2 camera inspection of the flue and clearances. For a Gelco metal stack, that means checking the cap, top plate, storm collar, every snap-lock joint, and the inner wall condition. For masonry, it means camera work inside the flue and a look at the liner.
- 2
Repair or install. Based on what we find, we plan the repair. That might be a new cap assembly, re-seating joints, replacing a top plate, or relining. We use parts that fit the system and match its listed clearances.
- 3
Test. After the work, we confirm the draft, re-check clearances, and make sure water sheds the way it should. You get photos of the finished job.
- 4
Warranty. We explain what the repair covers and what it doesn’t, in plain terms, so you’re not guessing later.

AfterGelco Products We Service & Install in Pasadena
We service and install the Gelco components that top off a chimney system and keep it weather-tight. That includes chimney caps and top-plate assemblies, storm collars, and matching snap-lock sections for prefabricated metal chimneys. For masonry, we work with Gelco stainless flex liner kits and handle sizing and installation to the flue’s actual dimensions. We also handle waterproofing on the masonry that surrounds these systems. If you’re not sure what you have up there, we’ll tell you after we look.
We Also Service These Brands
We’re not a single-brand shop. Alongside Gelco, we work with DuraFlex flexible liner systems and HeatShield resurfacing products, and we service and install systems from Olympia Chimney, Famco, and Copperfield. That range means we can solve the problem in front of us with the right part, rather than forcing every chimney into one maker’s catalog.
FAQs – Gelco Chimney Cleaning Service in Pasadena
No. We are an independent service provider. We’re not affiliated with, authorized by, or endorsed by Gelco, and we don’t sell their products. We service Gelco systems against the manufacturer’s published installation and clearance specifications, and our work is backed by documentation, not a factory relationship.
Yes. Where the system is serviceable, we use genuine Gelco replacement components: caps, storm collars, top plates, and matching snap-lock sections. Matching the profile keeps the clearances and fit correct. We don’t stock OEM parts or claim to be a Gelco dealer; we source what fits your system.
Most Gelco cap, collar, and top-plate work is a single visit, typically a few hours depending on roof access and the condition of the system. A Level 2 inspection plus repair can take longer if we find joint corrosion or a compromised inner wall. We’ll give you a realistic timeline in the written estimate before any work starts.
We cover Gelco chimney caps and top-plate assemblies, storm collars, snap-lock sections for prefab metal chimneys, and stainless flex liner kits for masonry relining. If it’s part of the exterior chimney system or the flue, we can inspect it and tell you what it needs.
Properly done service with parts that fit the system and respect its listed clearances is what keeps a warranty intact; the risk comes from mismatched parts and improvised repairs. We can’t speak for Gelco’s warranty terms, but we document our work so you have a record if a question ever comes up.
Cost depends on what we find: a standard sweep and inspection, a cap and top-plate replacement, or relining are all different jobs. We give you a written estimate before any work begins, and the estimate is free. Call (833) 334-7488 for an exact quote.
