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.

Why Top Hat Chimney Is Sterling’s Preferred Chimney Cap & Crown Company
Sterling homeowners tend to know their neighbors and they talk. When a crew does honest work on one Cascades townhome, word gets to three more on the same street by the following weekend. That is how we built our reputation in Sterling, one inspected chase at a time. The number you hear on the phone is the number on the invoice, and Wendell puts his name on the work. He will run into you again at the Giant on Cascades Parkway, and he knows that.
We are not a franchise that rotated in last spring. We are locally owned and owner-operated, with a published address and license number. Our technicians are background-checked and arrive in uniform, with a real arrival window. If that window slips, we call. Seniors and veterans always get 10% off, and there is no trip charge for calls inside the county. A live person answers every call around the clock, and it may well be Wendell.
Our Chimney Cap & Crown Services in Sterling
Here is what we do most often with our Chimney Cleaning & Sweep in Sterling, and what each job actually involves. If your issue is not listed, call (571) 518-5470 and describe it. We will tell you honestly if it can wait, or if it needs a closer look.
Cap Installation
A missing or undersized cap lets rain, leaves, and nesting animals straight into the flue. In Sterling’s humid summers, that trapped moisture accelerates rust and deteriorates liner joints through the off-season. We install Copperfield and Famco caps sized to your exact flue dimensions, and we will tell you plainly if a simple cap is all you need or if there is more going on inside.
Cap Replacement
Rusted or storm-damaged caps are common across Sterling, especially on 1980s and 1990s prefab fireplaces where the original galvanized chase covers have reached the end of their service life. Replacement involves removing the old cap, inspecting the flue and chase interior by camera, and installing a new cap rated for your unit. If we find water already in the firebox, the photos go to you on the spot.
Multi-Flue Cap
In Cascades and Countryside townhome clusters, shared chases frequently house two prefab flues side by side. A single multi-flue cap with a custom chase cover protects both flues while sealing the shared opening. We recently capped two side-by-side flues on a Cascades Parkway townhome where the original galvanized chase cover had rusted through, letting water run down into both fireboxes. Our tech showed the owner camera footage of the corroded metal firebox panels before installing new Famco multi-flue caps with a custom chase cover, and we photographed the shared chase condition so the neighbor’s HOA repair claim had clear evidence.
Crown Repair
Older Sterling Park brick chimneys, many built in the 1960s and 70s, have clay tile crowns and liners that hairline-crack from decades of freeze-thaw cycling. Water slips through those cracks, freezes and expands, and spalls the mortar joints below. We repair crowns with a reinforced crown coat or Heatshield in Sterling to seal the surface, or rebuild the crown entirely if it has crumbled. Either way, we will show you the damage on camera before touching anything.
Crown Coating
When the crown is intact but weeping water through micro-cracks, a flexible crown coating can bridge those gaps and prevent future spalling. This is a lower-cost option than a full crown rebuild and makes sense on Sterling Park brick chimneys where the crown is still structurally sound. We will tell you if a full rebuild is genuinely necessary or if coating buys you another ten years.

Trusted Brands We Service in Sterling
We install and service caps, chase covers, and crown systems from Copperfield, Famco, DuraFlex, and Gelco, and we keep common Sterling sizes and configurations on the truck. That matters on a multi-flue townhome chase in Cascades, where a special-order cover can hold up a repair for weeks. If your unit is still under manufacturer warranty, we work with those brands directly to process claims. The name on the box matters less to us than whether the part fits and lasts. It’s your flue that has to breathe.
Common Chimney Cap & Crown Problems We See in Sterling Homes
- Rusted chase covers on 1980s and 90s prefab fireplaces. The original galvanized metal covers on thousands of Sterling prefab units have simply rusted out. Water runs down into the metal firebox, starting a rust-through that eventually requires full system replacement rather than a simple cap swap.
- Hairline cracked clay tile crowns on older brick chimneys. Sterling Park’s 1960s and 70s homes have crowns that look fine from the ground but show spider cracking up close. Water penetrates, freezes, and spalls the mortar. Crown coating or repair prevents the slow downward spiral.
- Shared chases concentrating runoff in townhome clusters. When two flues share one exterior chase, a single failed cap or chase cover funnels water into two fireboxes at once. We photograph everything and document the shared condition, because HOAs and neighbors often dispute who pays.
- Undersized or missing caps on flues that never had one. Some Sterling homes were built with no cap at all, or with a cap the builder never intended for the actual flue size. Rain, birds, and leaves enter freely, and the damage compounds every season.

FAQs - Chimney Cap & Crown in Sterling
The legal answer depends on your HOA documents and where the failure originated, but the practical answer is that we photograph and document everything so each owner has clear evidence. Typically, a shared chase cover is common property, while each unit’s flue and firebox belong to that owner. We give you written, dated documentation of what we found and where, which has helped many Sterling homeowners settle HOA and neighbor disputes. Call (571) 518-5470 to have the chase inspected and documented.
No, and we will tell you that directly. Factory-built zero-clearance fireplaces from the 1980s and 90s cannot be relined the way a masonry chimney can. When one fails or rusts through, the entire unit must be replaced. That is why a cap and crown inspection is genuinely important on an aging prefab in Sterling: catching water intrusion early is the difference between a $300 cap and a multi-thousand-dollar Sterling Fireplace Services replacement. Call (571) 518-5470 and we will show you on camera exactly what your firebox looks like.
Yes, it can be. A cracked cap lets water directly into the flue, bypassing the crown entirely. Over Sterling winters, that water freezes and widens the existing crack, and over humid summers it sits against the clay tile liner and mortar joints. We will replace the cap and inspect the interior by camera to confirm the crown is still doing its job. If it is, you are done for under $340 in most cases. Call (571) 518-5470 for a free estimate.
Once a year, burn or no burn. Chimneys break in the off-season too, and a rusted chase cover on a Countryside prefab does not wait for you to light a fire to keep failing. Annual inspection catches cap and crown issues before water reaches the firebox. On a 30 to 40 year old prefab system, that one annual look can save you the full replacement cost. Call (571) 518-5470 to book.
Yes. A custom chase cover is fabricated to match your exact chase dimensions and flue terminations, regardless of whether the two flues end at different heights. We measure, fabricate, and install custom multi-flue caps and chase covers for Sterling townhomes weekly. The camera footage and a plain-English verdict, every time, no exceptions. Call (571) 518-5470 to schedule a measurement.
