Fast, Reliable Chimney Repair Across Unionville
If your chimney is leaking, crumbling, or pulling away from the house, most Unionville homeowners need a technician on-site within a day or two and a repair that lasts. We keep trucks stocked for the subdivisions off Highway 74 and the neighborhoods around Unionville Elementary, and we answer our phones with a live person 24 hours a day. Call (844) 803-1545 and we’ll give you a straight answer about what you’re seeing and when we can be there.
Unionville sits inside Union County, one of the fastest-growing counties in North Carolina over the past two decades, meaning the dominant housing stock is large tract homes built between 2000 and 2015 - homes overwhelmingly fitted with factory-built (zero-clearance) prefabricated fireplaces rather than traditional masonry. Those units are now 10-25 years old and hitting the window where steel fireboxes, refractory panels, and damper assemblies commonly fail, making inspection and component replacement - not just Chimney Cleaning & Sweep - Unionville - the real service need here. We’ve been working these homes since they were new, and we know which builder-grade components start to go first.
Why Hearthstone Chimney Co. Is Unionville’s Preferred Chimney Repair Company
We’ve been serving Union County for over 42 years, since 1984, and we’ve watched Unionville grow from farmland to the subdivisions off Weddington Road and Ridge Road. That longevity means something here. We’re not a franchise that rotates crews every season, and we’re not a one-truck operator who might answer the phone next year or might not. When we repair a chimney in the Brandon Oaks or Wesley Meadows neighborhoods, we expect to drive past it for decades. We act accordingly.
Our technicians are background-checked, uniformed, and carry Level-2 camera equipment on every truck. Most Unionville repairs are completed in a single visit because we stock professional-grade materials from DuraFlex, HeatShield, and Famco, and we give no-hassle upfront pricing - the number on the estimate is the number on the invoice. Every job is backed by our 90-Day Done Right Promise in writing, no arguing. If it’s not right, we come back.
A real person answers our phones 24 hours a day, 7 days a week. Not a voicemail, not a callback queue. When water is dripping through your ceiling during an ice storm, that matters.
Our Chimney Repair Services in Unionville
Mortar Repointing
The freeze-thaw cycles that hit Unionville each winter - ice storms followed by quick Piedmont thaws - work water into mortar joints, then expand it as ice. By spring, the mortar in homes near the Unionville town center or along Potter Road is often crumbling. We grind out failed joints to proper depth and repoint with color-matched mortar that bonds to the existing brick. Done right, and we stand behind it.

Spalling Brick Repair
Spalling - brick faces flaking off from moisture trapped inside - is common in Unionville’s older masonry, including the occasional pre-2000 home near the original crossroads. The spalled brick must come out, the source of moisture must be found, and replacement brick must match. We document the damage with photos you can see and give you a plain-English verdict on whether spot repair or larger rebuilding makes sense.

Chimney Waterproofing
Unionville’s pattern of wet winters and humid summers means chimneys absorb moisture year-round. We apply vapor-permeable sealers that let the chimney breathe while blocking water penetration, critical for the prefabricated chimney chases in subdivisions like those off Sardis Road. A waterproofed chimney sheds rain instead of soaking it in, which protects the framing around factory-built units that many homeowners never think to check.

Flashing Repair
Step flashing where the chimney meets the roof is a common leak point in Unionville, especially on the steep-pitched roofs common in 2000s-era construction. Our technicians lift shingles carefully, replace corroded or improperly seated flashing with copper or galvanized stock, and seal with professional-grade compounds. We also inspect the surrounding decking for rot that the leak may have already caused.

Chimney Rebuilding & Tuckpointing
When deterioration has gone past spot repair, we rebuild from the roofline up or perform full tuckpointing of the chimney stack. In Unionville’s newer subdivisions, this more often applies to decorative brick veneer or older homes near the historic district; for prefab units, we may need to rebuild the chase or replace the entire factory-built system. Either way, you get photos, a plain-English verdict, and no-hassle upfront pricing before we start.
Our Chimney Repair team also handles chimney cap and crown work throughout Union County. If your chase cover has rusted through or your crown has cracked, we can address that too.

Common Chimney Repair Problems We See in Unionville Homes
- Rusted-through chase covers on prefab chimneys. The thin galvanized chase covers installed during Union County’s 2000s building boom have reached their service life. Technicians working the Unionville subdivisions routinely find these covers lifted at the seams or perforated by rust, letting rainwater pool around the flue pipe and rot surrounding framing long before interior staining appears.
- Cracked refractory panels in factory-built fireboxes. The prefabricated fireplaces in Unionville’s dominant housing stock use refractory cement panels that crack from thermal cycling after 10-20 years of use. Homeowners often mistake this for cosmetic wear, but cracked panels can allow heat transfer to combustible framing - a genuine safety issue that requires professional inspection.
- Freeze-thaw damage to mortar and crowns. The NC Piedmont’s periodic winter ice storms create repeated freeze-thaw cycles particularly destructive to chimney crowns, mortar joints, and the thin sheet-metal chases covering prefab units. Water enters small cracks, freezes overnight, and widens the damage each cycle.
- Neglected annual service leading to creosote buildup. Unionville’s mild shoulder seasons encourage homeowners to skip annual chimney service, allowing slow creosote accumulation from infrequent, smoldering fires that never fully heat the flue. This accelerates corrosion of metal components and increases fire risk in both masonry and prefabricated systems.
