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.
Olympia Chimney Chimney Repair in Denton: What to Know First
We provide independent Olympia Chimney chimney repair in Denton, Texas, for homeowners who need mortar repointing, spalling brick repair, chimney waterproofing, flashing repair, and full rebuilds. Most Olympia Chimney jobs we book are inspected within 48 hours and completed within a week, with a written price delivered before any work starts. We’re not affiliated with Olympia Chimney - we buy their liners and components through Haven’s buying network and install them under our own 365-Day Done Right Promise.
This page is for Denton homeowners who already have an Olympia Chimney liner, cap, or crown and need someone who knows how these products age in North Texas clay soil and summer heat. Call (940) 373-6912 for a free estimate, or bring us a competitor’s written quote for a free second opinion.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 316Ti flexible liner collars crack at the top plate weld. The 316Ti series handles Denton’s freeze-thaw cycles well in the flue itself, but the collar weld sees concentrated stress where the liner exits the masonry. We cut back to sound metal, install a custom-fabricated top plate with a stress-relief bend, and seal with HT silicone rated to 572°F. This costs less than a full liner replacement and preserves your existing 316Ti run.
- Olympia Chimney Gelco-compatible caps corrode at the mesh-to-frame joint after 7-10 years. Denton’s alkaline clay runoff accelerates galvanic corrosion where dissimilar metals meet. We stock replacement Gelco-compatible frames through Haven’s network and can often reuse your existing mesh if the frame is the only failure point. If both are gone, we quote a full cap in stainless or copper before ordering.
- Olympia Chimney poured-in-place HeatShield applications delaminate in offset flues. HeatShield works when the flue is straight; in Denton’s 1960s-1980s ranch homes with 30-degree offsets, the material shears during cure. We camera-scan first. If we find an offset, we pivot to a DuraFlex 316Ti liner or partial rebuild rather than sell a repair that won’t hold.
- Olympia Chimney crown sealant fails at the flue tile interface. Their brush-on crown repair product is decent, but it needs a 1/4-inch bond break around the flue tile expansion joint. Most DIYers and some pros skip this. We remove the failed sealant, cut the bond break with a masonry blade, and reapply with a fiberglass-reinforced slurry that moves with the tile.
- Olympia Chimney Famco dampers seize in homes with negative pressure issues. The Famco top-sealing damper is a good product, but it can’t overcome a house that’s pulling 8+ Pascals negative. We measure draft and house pressure before condemning the damper. Often the fix is a makeup air strategy, not a new damper - and we say so in writing before spending your money.
Our Olympia Chimney Chimney Repair Process

- 1
Call and schedule. A live person answers. We ask what you’re seeing - water stains, brick dust, draft smell - and book a Level 2 inspection with camera scan. You’ll get a text when your tech is en route.
- 2
NFPA 211 Level 2 inspection. We run a camera down the flue, photograph the crown, cap, and exterior masonry, and record draft readings. You watch the footage with us. Corrine Halstead’s rule: the camera doesn’t guess - and neither do we.
- 3
Written scope and price. Before any repair starts, you get a single-page document with what we found, what we’ll do, what parts we’ll use (Olympia Chimney OEM or qualified equivalent from DuraFlex, HeatShield, Gelco, or Famco), and the exact price. No surprises, no “we’ll see once we open it up.”
- 4
Repair with documented steps. We photo each stage: mortar mix ratio, liner insertion depth, crown slope measurement, final cap placement. These go into your record under Haven Standard Clause 4.
- 5
Post-repair test and sign-off. We run another camera pass, verify draft, and have you initial the completed scope. The 365-Day Done Right Promise activates at signature.
- 6
Cleanup and archive. We haul debris, sweep the hearth area, and upload your photo record to our archive - accessible if you sell the home or need warranty service.

Why Denton Homeowners Call Emberly Chimney Cleaners Denton for Olympia Chimney Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a growing share of our Denton work involves Olympia Chimney products installed during the 2015-2020 liner replacement boom. We know which 316Ti runs were factory-welded versus field-cut, which HeatShield batches had the early delamination issue, and where to source Gelco-compatible frames without the markup of a “brand-authorized” middleman.
Our technicians are background-checked, uniformed, and named on your appointment - not dispatched from a pool. You get a text when they’re en route. Materials come through Haven’s buying network from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, which keeps prices honest and options open.
The 365-Day Done Right Promise means if it’s not done right, we make it right. No paperwork chase, no “call the manufacturer.” Clause 1 of the Haven Standard requires the written price before work starts; Clause 4 requires the photo record. Both are automatic, not optional.
FAQs
No - but only if the repair uses OEM or equivalent-spec parts and follows installation guidelines. As an independent Olympia Chimney service provider, we source compatible components through Haven’s network and document every step. If your liner is still under Olympia Chimney’s original warranty, we flag that in your file and note which parts qualify. Call (940) 373-6912 and we’ll check your install date against their terms.
Most single-component repairs - collar replacement, cap swap, crown seal - finish in 2-4 hours. Tuckpointing or partial rebuilds run 1-2 days depending on mortar cure time and weather. We don’t rush cure cycles; North Texas humidity in July can add half a day to mortar set. You’ll know the timeline in writing before we start.
Replace when the liner shows multiple perforations, the masonry shell has lost structural integrity, or repair costs exceed 60% of replacement. We camera-scan first and show you the footage. In Denton’s clay-heavy soils, we’ve seen chimney bases shift while the liner above stays sound - in those cases, a partial rebuild with liner preservation saves thousands. We’ll tell you straight which side of the line you’re on.
Standard collars, caps, and adapters ship through Haven’s network in 2-3 business days. Custom 316Ti sections or unusual diameters can take 5-7 days. We don’t start work until parts are in hand - no “we’ll come back” scheduling. If your situation is urgent, we stock DuraFlex and Gelco equivalents that meet the same spec and may install faster.
Spalling brick lets water into the wall cavity. A cracked liner can leak combustion gases, including carbon monoxide, into living space. Creosote infiltration through failed mortar joints creates hidden fire paths. These aren’t abstract risks - we’ve documented each one in Denton homes. The repair cost doesn’t go down with waiting; it goes up. Call (940) 373-6912 for a free estimate and we’ll show you exactly what your chimney looks like inside.
