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 Repair in Roanoke: What to Know First
We provide independent Gelco chimney repair throughout Roanoke, and most jobs are completed in a single visit with upfront pricing agreed before we start. Typical Gelco repairs run from $280 for localized mortar repointing to $2,800 for partial chimney rebuilding, and we always inspect with a camera first so you see what we see. This page is for homeowners in Roanoke who own a Gelco chimney component - cap, crown, or chase cover - and need straight talk on what’s failing, what it costs, and who can fix it without voiding your warranty. Call (540) 787-3302 anytime; a live person answers, day or night.
How Gelco Products Fail - and How We Fix Them
- Gelco Multi-Flue Chimney Caps (Model A and C Series) - The stainless mesh on these caps fatigues at the weld points after 12-15 years in Roanoke’s freeze-thaw cycle, especially on homes above 1,400 feet in South Roanoke and Grandin. Water gets past the mesh, saturates the flue tile, and the freeze pushes the crown apart. We replace with Gelco-spec 304 stainless or upgrade to 316L if you’re in a wind-driven rain zone near the Blue Ridge, and we re-bed the cap with a tapered wash that sheds water toward the drip edge.
- Gelco Single-Flue Caps with Leg Kits (L-Series) - The tension bolts corrode where Roanoke’s acid rain meets coal-soot residue, a combination we see often in older homes off Patterson Avenue and Williamson Road. The legs loosen, the cap tilts, and water pools on the crown. We pull the old hardware, chase the threads, and install Gelco-compatible galvanized or stainless leg kits with nylock hardware that won’t back off.
- Gelco Chase Covers (Pre-2010 Galvanized Stock) - These were built with 24-gauge galvanized steel that rusts through at the pan corners in 8-12 years, right where condensation collects. We’ve replaced dozens on townhomes in Cave Spring and along Brambleton Avenue. We fabricate a replacement from Gelco-compatible 304 stainless or copper, with cross-breaks in the pan to prevent ponding, and we seal the skirt with a butyl tape backup under the counter-flashing.
- Gelco Top-Mount Dampers (TD Series) - The cast-aluminum frame cracks at the throat hinge pin when homeowners in Roanoke burn green oak or hickory, which is most of the firewood sold around here. The damper jams open, and you’re losing heat all winter. We diagnose with a Level-2 camera inspection, source the correct Gelco throat replacement or a compatible HeatShield retrofit if the frame is too far gone, and verify seal with a smoke test.
- Gelco Crown Repair Compound Failures - When a previous contractor slathered Gelco’s brushable crown sealer over active cracks without opening them first, the compound bridges the gap and traps water underneath. We see this on DIY jobs in Wasena and Raleigh Court. We grind out the crack to 1/4 inch, chase it with a grinder, and fill with a proper Portland-based patching mix that moves with the masonry, then top with a breathable siloxane sealer.

FAQs
No, if the work is done by a qualified technician using Gelco-spec or compatible parts. As an independent Gelco service provider, we use OEM or equivalent-grade materials and document everything, so any remaining warranty stays intact. Call (540) 787-3302 if you want us to review your original purchase paperwork.
Most are completed in a single visit of two to four hours. Chase cover replacements or rebuilds needing scaffolding may schedule a second day. We’ll tell you before we start.
If the cap mesh is fatigued but the crown and flue tile are sound, repair makes sense. If the crown is spalling or the flue is cracked, replacing the cap alone wastes money. Our camera inspection shows which category you’re in.
Some pre-2010 galvanized chase covers and L-Series leg kits are discontinued. We stock compatible stainless alternatives or fabricate in-house. We never leave you waiting on a back order without a plan B.
Most repairs fall between $280 and $1,450, with partial rebuilds reaching $2,800. We inspect free, quote upfront, and honor our standing offers: $50 off any repair over $250, free second opinions on written estimates, and a permanent 5% senior and veteran discount. Call (540) 787-3302 to schedule.
