Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterGelco Chimney Cleaning & Sweep in Alexandria: What to Know First
Gelco chimney cleaning and sweep in Alexandria typically runs $189 to $289 for a standard annual job, and most Gelco owners get on our schedule within three to five days. We’re an independent Gelco service provider, which means we work on these systems regularly without being tied to a manufacturer’s script. If you own a Gelco chimney system or cap and need it cleaned, inspected, or evaluated, call (571) 521-4837 and you’ll get a straight answer before you get an invoice.
This page is for Alexandria homeowners who have a Gelco liner, cap, or chase cover installed and want someone who knows how these particular products behave after a few Mid-Atlantic winters. Wendell Pike and our crew have been inside enough Gelco installations around Old Town and the neighborhoods west of Quaker Lane to know what holds up and what doesn’t.
Key takeaways:
- Gelco liners and caps are solid products, but they’re only as good as the installation around them.
- We clean and inspect the whole system, not just the brand name on the cap.
- Upfront pricing before we touch anything. The number you hear is the number on the invoice.
How Gelco Products Fail - and How We Fix Them
Gelco makes good stainless steel, but Alexandria’s humidity and temperature swings find the weak points. Here’s what we actually see on service calls:
- Gelco stainless steel caps with surface rust at the weld points. The mesh and hood hold up, but the spot welds where the screen meets the frame start showing rust after five to seven years of Alexandria’s damp springs and salty river air. We pull the cap, clean the rust, treat the metal, and tell you honestly whether it’s got another few seasons or it’s time to replace it.
- Gelco flexible liners with creosote glaze in the ridges. This is a real theme. The corrugated ridges of a Gelco flex liner grab creosote faster than a smooth wall, especially on wood-burning fireplaces that don’t get hot enough burns. A standard brush pass won’t always cut third-degree glaze. We use rotary cleaning heads and let the camera confirm the ridges are clear before we call it done.
- Gelco chase covers with standing water after storms. Alexandria gets quick, hard downpours, and if a Gelco chase cover wasn’t pitched right or the caulk has separated, water sits on top. Standing water on stainless eventually becomes a pinhole leak. We pull the cover, check the flashing, and repair or re-pitch the install so water runs off instead of pooling.
- Gelco caps clogged with Alexandria’s cottonwood and crepe myrtle debris. The mesh on Gelco caps does its job, but fine airborne debris still gets through and builds up on the flue tile below. We’ve pulled caps in Del Ray that had a half-inch of packed material sitting on top of the damper. During a sweep, we clear the cap, the mesh, and the flue path below it, not just the firebox.
- Gelco liner kinks at the top transition. Some Gelco flex liners installed years ago weren’t supported properly at the crown, and the weight of the liner combined with expansion and contraction works a kink into the bend. That kink becomes a creosote trap and a draft killer. We see it on the camera, straighten or re-support the liner, and the draft usually returns immediately.
Your flue doesn’t care how the fire looks. It cares how it breathes. A Gelco product with a restricted path is still a restricted flue, and that’s what we find and fix.
Our Gelco Chimney Cleaning & Sweep Process
Every Gelco job we do in Alexandria follows the same order. Nothing surprising, nothing skipped.
- 1
You call, we quote. You tell us what you’ve got: wood-burning fireplace, insert, gas log setup, or a furnace flue. We give you the price before the truck moves.
- 2
We arrive on time and cover everything. Drop cloths in front of the hearth, a vacuum running with a true HEPA filter. Our crew wears uniforms and shoe covers, and the sweep who shows up introduces himself.
- 3
We inspect first. Wendell or one of his crew runs the camera through the Gelco cap, down the liner or flue tile, and into the firebox. You see the footage on the spot. If the cap has to come off to get a clean view, it comes off and we tell you why before we touch a tool.
- 4
We clean what needs cleaning. First-degree creosote is a brush job. Third-degree is a glaze. We match the tool to what the camera showed, not a guess. Gelco flex liners get rotary treatment when the ridges show glaze.
- 5
We put it back and test the draw. The cap goes back on, the damper gets checked, and we light a smoke test or check the draft with a meter. If it doesn’t pull right, we find out why before we leave.
- 6
You get a summary and a written guarantee. The 90-Day Done Right Promise is stamped on the invoice. If we missed something or the job isn’t right, one call brings us back at no charge.
That’s the whole process. No mystery, no surprises, and no invoice numbers that change between the phone call and the front door.
What Gelco Chimney Cleaning & Sweep Costs in Alexandria
Here’s what we charge for the most common Gelco jobs in Alexandria. These are real numbers, not teaser rates:
- Standard sweep and Level 1 inspection (fireplace or wood stove): $189 to $249
- Heavy creosote removal with rotary cleaning (common on Gelco flex liners): $275 to $340
- Full cap removal, cleaning, and re-seal: $95 to $140 when done during a sweep
- Camera inspection added to any sweep: $75 - and we don’t charge for it if we’re already doing the job
- Chase cover inspection and cleaning: $65 to $95
What moves the price is how much creosote has built up, whether the cap needs to come off, and how many flues you have. A two-flue rowhouse in Old Town costs more than a single-flue colonial out by Seminary Hill. We’ll tell you the exact number before the job. Call (571) 521-4837 for an estimate, and remember: no trip charge inside the county.
Why Alexandria Homeowners Call Top Hat Chimney for Gelco Work
We’ve been doing this since 1999, longer than most of the national franchises have had a truck in Alexandria. Wendell Pike started Top Hat Chimney because he got tired of seeing chimney companies quote one price and pad another, and that has not changed in over two decades. The phone rings and a live person answers. It may well be Wendell himself. The techs who show up are background-checked and uniformed, and they give you a real arrival window.
We also service DuraFlex and HeatShield systems, so if your Gelco setup shares a chimney with another liner we can evaluate the whole thing in one visit. And every job, Gelco or otherwise, gets the 90-Day Done Right Promise in writing. If it doesn’t need doing, Wendell will tell you that, too. That’s not how every company operates.
Ask anyone on your street. In Alexandria, Top Hat has been the name behind the cap for a long time.
FAQs
No. Regular professional cleaning and inspection is exactly what Gelco expects for their liners and caps. What voids warranties is neglect, DIY damage, or an installer who cuts corners. We clean to manufacturer guidelines and document everything with camera footage. If you ever need to file a warranty claim, you’ll have the records to back it up.
Once a year, burn or no burn. Chimneys break in the off-season too, especially in Alexandria where humid summers work on metal components even when the fireplace is cold. If you burn more than two cords a season or burn a lot of pine, you may need a mid-season sweep. We’ll tell you after the first inspection what your pace should be.
Most Gelco caps can be cleaned and re-sealed, and most liners just need a proper sweep. But if the camera shows corrosion through the stainless or a kink that has creased the metal, repair isn’t honest advice. We’ll show you the footage and let you see exactly what we see before we recommend anything. Free second opinions on any written estimate, too.
Most Gelco sweep jobs get scheduled within three to five days. If you’ve got a drafting problem or visible smoke backing up, tell us when you call and we’ll work you in sooner. The phone is answered around the clock, so call (571) 521-4837 and we’ll find a time. No voicemail box. No call center.
Yes. Rowhouses in Old Town, Del Ray, and Rosemont have their own quirks: shared party walls, older terra cotta flue tiles, and tighter access. Wendell and his crew have been inside those houses for years and know what to expect before the ladder comes off the truck. The camera footage and a plain-English verdict, every time, no exceptions.
If you own a Gelco system and you’re not sure when it was last touched, call (571) 521-4837. We’ll give you a price, a time, and an honest answer.
