Fast, Reliable Chimney Cap & Crown Across Round Rock
Chimney cap and crown repair in Round Rock typically runs $180-$650 depending on whether you’re sealing a hairline crack or replacing a rusted cap on a prefab chase, and our Chimney Cap & Crown technicians can usually reach homes in the 78664, 78665, 78682, and 78683 zip codes same day or next day. We’re familiar with the builder-grade chase systems that dominate subdivisions from Teravista to Walsh Ranch, and we stock caps and crown coating materials sized for those units so we’re not ordering parts while water drips into your firebox. Call (844) 803-1545 and a live person will pick up, 24 hours a day.
Why Hearthstone Chimney Co. Is Round Rock’s Preferred Chimney Cap & Crown Company
We’ve been answering calls from Round Rock homeowners since before Dell’s expansion turned farmland into neighborhoods. In 42 years of service, we’ve watched this city grow from a quiet stop on I-35 to a major suburb, and we’ve tracked what that growth means for chimneys: thousands of prefab fireplaces installed fast during the 1990s and 2000s builds, now hitting the age where caps corrode and crown seals fail.
Our technicians carry background checks, wear uniforms, and complete most cap and crown jobs in a single visit. We document every inspection with photos you can see and a plain-English verdict - no jargon, no surprises. The 90-Day Done Right Promise covers every job in writing: if it’s not right, we come back, no arguing, no paperwork chase.
A live person answers our phones 24/7, not a callback queue. When you’re staring at a water stain spreading across your ceiling near Old Settlers Boulevard or you smell smoke backing up into your living room in Stone Canyon, that matters.
We’re not a chain sending whoever’s available from Austin or San Antonio. We know the difference between a masonry crown on a pre-1980s home near Mays Street and the metal chase cover on a 2005 Teravista build, and we arrive with the right materials.
Our Chimney Cap & Crown Services in Round Rock
Cap Installation
New cap installation in Round Rock runs $220-$380 for standard single-flue galvanized or stainless steel units on prefab chase systems. In neighborhoods like Brushy Creek and Walsh Ranch, we regularly find original caps that were never upgraded from the thin builder-grade aluminum that came with the house - those corrode through in 8-12 years in our climate. We install Famco and Copperfield caps sized to your exact flue or chase dimensions, with proper screening to keep out the squirrels and starlings that nest in Round Rock’s mature live oaks.
Cap Replacement
Cap replacement in Round Rock costs $180-$320 when the existing mounting flange is still sound, or $340-$520 if the chase top itself has rusted through and needs rebuilding. The February 2021 freeze caught many homeowners off guard; fireplaces that sat idle for years were suddenly burning daily, and we’ve since replaced dozens of caps in the 78665 zip code where thermal cycling cracked aged metal. We match replacement caps to your chase manufacturer when possible, or fabricate custom solutions for odd-size flues.
Crown Repair
Crown repair on masonry chimneys in Round Rock’s older homes - mostly concentrated near the Old Town core and along Sam Bass Road - typically costs $280-$450 for crack sealing and resurfacing. Our Central Texas pattern of drought followed by sudden heavy rains (May and October are especially hard on crowns) forces water into hairline fractures that freeze and expand during those rare cold snaps. We use professional-grade crown coating, not hardware-store caulk, and we slope the repair so water runs off rather than pooling.
Crown Coating
Preventive crown coating in Round Rock runs $180-$280 and adds 10-15 years of service life to a sound masonry crown. For homeowners in Georgetown or Round Rock who plan to stay put, this is a square deal: stop the crack before it starts. We apply HeatShield or similar professional-grade elastomeric coating in weather-appropriate conditions - not during our summer 100-degree stretches when product curing fails, and not in winter when the substrate is too cold.

Trusted Brands We Service in Round Rock
We stock caps, chase covers, and crown coating materials from DuraFlex, HeatShield, and Famco in sizes that fit the prefab chase systems common to Round Rock’s 1990s-2010s housing stock. That means no waiting on shipping while rain enters your chimney. For custom or oversized applications - the occasional masonry chimney in Old Town, or a multi-flue setup in a larger home near Forest Creek - we work with Copperfield for fabricated solutions. Every material we use is professional-grade; we don’t substitute builder-grade aluminum and hope you don’t notice the difference in five years.
Common Chimney Cap & Crown Problems We See in Round Rock Homes
- Rusted-through chase covers on prefab units in Teravista and Walsh Ranch. The galvanized steel caps installed during the 1998-2005 build-out have reached or exceeded their service life. Homeowners often notice rust stains on siding or a dripping sound inside the chase before they see the hole.
- Cracked crowns from thermal shock after years of neglect. Round Rock’s brief, intense cold snaps - like the 2021 freeze - hit masonry that hasn’t seen sustained heat in years. The crown expands and contracts unevenly, and a crack that was minor in October becomes a water entry point by January.
- Missing or damaged spark arrestor screens. Our live oak canopy and mild winters mean squirrels are active year-round. A cap without intact screening invites nesting, which blocks draft and creates fire hazards. We find this especially in mature subdivisions like Brushy Creek where tree cover is dense.
- Improperly sealed crown-to-flue joints on older homes near Mays Street and Sam Bass Road. Previous repairs using consumer-grade sealant have dried and pulled away, leaving gaps that channel water directly into the chimney structure. We remove failed material and reseal with products rated for chimney exposure.
