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.

How HeatShield Products Fail - and How We Fix Them
HeatShield makes a ceramic-based coating system designed to restore fireboxes and smoke chambers without a full rebuild. It’s a good product when applied correctly. But it fails in predictable ways, especially in Fairfax where humidity swings and freeze-thaw cycles put real stress on fireplace masonry. Here’s what we see most often:
- Flaking at the smoke chamber seams (HeatShield Smoke Chamber Repair System). The smoke chamber is the roughest area to prep, and if the original surface wasn’t cleaned down to solid masonry, the coating loses its grip. We see this on older Fairfax homes near the Government Center area where fireplaces were built in the 1960s and 70s. Fix: strip the loose material back to sound substrate, re-prime with the HeatShield base coat, and build up properly. The prep is the job.
- Hairline cracking in the firebox refractory (HeatShield Firebox Restoration System). Thermal expansion takes its toll. A fireplace that gets hot fires in November and sits cold through February thaws will crack any rigid coating eventually. If the cracks are superficial, a re-coat usually solves it. If the bricks behind are shifting, we’ll tell you that before quoting anything.
- Discoloration without structural failure at the firebox floor. This is the one we tell people to ignore most often. HeatShield coatings darken with use. Dark doesn’t mean damaged. If the surface is intact, you don’t need to spend money. Wendell has walked away from jobs like this more times than he can tell you.
- Improper application by the original installer. HeatShield requires specific curing conditions and surface temperatures. If a previous contractor applied it when the masonry was too cold (a real risk in Fairfax basements in January), the coating never bonds right. You’ll see blistering or peeling within the first season. Fix: full strip and re-application under proper conditions.
- Water intrusion behind the coating due to cap or crown failure. HeatShield does not fix a leaky chimney. If the crown is cracked or the cap is missing, water gets behind the coating and pushes it off from the back. We check the crown and cap on every single HeatShield job, because fixing the coating without fixing the water source is just buying time.
Our HeatShield Fireplace Services Process
- 1
Call and talk to a live person. You get Wendell or one of his crew on the phone, not a call center. We’ll ask what you’re seeing and when it started.
- 2
We show up on time and look first. No quote before inspection. We need to see the firebox, the smoke chamber, and the crown. We run a camera up the flue and show you what we find.
- 3
We make a call on parts: OEM HeatShield vs. aftermarket. For HeatShield-specific work, we use HeatShield coating materials because mixing brands voids the warranty and the chemistry matters. For parts like dampers, caps, and liners, we’ll use OEM when it makes sense and quality aftermarket when it saves you money without costing you durability. We’ll tell you which is which.
- 4
We give you a flat price before any work starts. The number we quote is the number on the invoice. That’s been true since 1999 and it’s not changing.
- 5
The repair is done, cured, and tested. We don’t rush the cure. Then we light a test fire where safe and check the draw.
- 6
You get the 90-Day Done Right Promise in writing. If it’s not right, one call brings us back. We stand behind every HeatShield job we do in Fairfax.

No trip charge inside the county, and we offer a free second opinion on any written estimate.
Why Fairfax Homeowners Call Top Hat Chimney for HeatShield Work
We’ve been running a brush through Fairfax chimneys since 1999, which means we’ve seen HeatShield systems installed well, installed poorly, and neglected for twenty years. Wendell Pike puts his name on the work and you’ll run into him at the hardware store on Saturday. That matters more than any warranty card.
Every job gets the 90-Day Done Right Promise in writing. Calls get answered by a live person, around the clock, and it may well be Wendell himself picking up. When we finish a HeatShield job, we tell you exactly what we did and exactly what we found. The camera footage and a plain-English verdict, every time, no exceptions. And if your fireplace also needs a new liner or cap, we work with DuraFlex and Gelco products too, so you’re not stuck juggling three contractors.
FAQs
We’re an independent HeatShield service provider, and if your fireplace or insert has a manufacturer warranty, we’ll check the terms before touching anything. In most cases, repairing a firebox or smoke chamber with HeatShield coating is exactly what the warranty anticipates, but we’ll verify before we start. Call (571) 624-2385 and we’ll look it up with you.
A properly applied HeatShield firebox or smoke chamber coating in a Fairfax home typically lasts 10 to 20 years, depending on how hard the fireplace works and whether water stays out. The two biggest killers are water intrusion from a bad cap or crown, and original prep that skipped the deep cleaning. We address both before we apply anything.
HeatShield coatings come in a limited range of finishes, so a perfect cosmetic match isn’t always possible, especially on older Fairfax fireplaces with decades of patina. We’ll tell you before we start if the repair will be visible. Function comes first: a firebox that holds heat and draws properly beats a pretty one that falls apart.
When the masonry behind the coating is sound, HeatShield is usually the better call: less demo, less mess, lower cost. But if the bricks themselves are spalling or the structure is shifting, no coating will save it and we’ll tell you that straight. If it does not need doing, we will tell you that too.
Most HeatShield repairs in Fairfax are booked within a week, and the repair itself is usually one visit. We don’t promise same-day service because we won’t rush a cure cycle. Call (571) 624-2385 and we’ll give you a real arrival window, not a four-hour gap.
If your HeatShield fireplace needs a look, call (571) 624-2385. We’ll set a time, show up, and tell you what’s actually going on up there. Free estimate, no pressure, and the price we quote is the price you’ll pay.
