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.
HeatShield Chimney Liner & Rebuild in Easton: What to Know First
We provide independent HeatShield chimney liner & rebuild service in Easton, with most jobs completed in a single visit and upfront pricing agreed before we start. Typical turnaround from call to completion is three to five business days during the off-season, two weeks once October hits. We’re not the cheapest option, and we don’t try to be - our customers want the job done right the first time, with a written guarantee behind it.
This page is for Easton homeowners who already have a HeatShield liner or are considering one, and need honest information about when to repair, when to rebuild, and what it actually costs. If your flue is showing gaps, your draft has dropped off, or you’ve been told you need a full liner replacement, call (610) 756-1504. We’ll send a technician with a camera, show you what we see, and give you a plain-English verdict.
How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Foam liner resurfacing - delamination in Easton’s wet freeze-thaw cycles. The cerfractory coating bonds to clay tile flues, but Easton’s winters swing hard: water gets behind the foam, freezes, and pops sections loose. We see this most in the older colonials near the Delaware Canal where the original clay is already porous. Our fix: remove the loose material, assess the underlying tile, and either re-apply with proper surface prep or recommend a stainless steel liner if the substrate is too far gone.
- HeatShield UL Listed stainless steel liners - seam separation at the flex joints. The UL1777-listed flexible liners work well until they’ve been through five or six Easton winters with heavy creosote buildup. The flex points fatigue. We inspect with a camera before quoting; if the separation is localized, we can cut and re-join with OEM couplers. If the pattern repeats along the run, we replace with DuraFlex or Gelco - whichever fits the chimney geometry better.
- HeatShield ProLiner - premature corrosion in oil-to-gas conversions. Easton has plenty of homes that switched from oil to natural gas in the 1990s. The ProLiner’s 316Ti alloy handles wood fine, but sustained exposure to gas flue condensate without proper sizing accelerates pinholing. We see this in the College Hill area. Fix: pull the ProLiner, resize the flue properly, and install a gas-rated liner - usually Gelco’s 316/439 combination for condensing appliances.
- HeatShield Joint Repair system - re-cracking at mortar joints within two to three years. The joint repair fills gaps between clay tiles, but it can’t compensate for a shifting chimney structure. In Easton, the freeze-thaw plus the clay soil beneath many foundations means movement. We warranty our joint repair work, but we’re upfront: if the chimney is moving, the joints will open again. Sometimes the right call is a full liner instead of chasing cracks.
- HeatShield CrownSeal - failure at the flue tile interface. CrownSeal is a crown repair product, not a liner, but it’s often installed by the same crews. When it shrinks away from the flue tile, water runs straight down into the liner system. We remove the failed CrownSeal, re-pour or re-cap the crown with proper slope and drip edge, then inspect the liner below for water damage. Two problems, one source - fix the source first.
Our HeatShield Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask about your appliance type, fuel, and what you’re experiencing. No diagnostic over the phone - that’s guessing.
- 2
Level-2 camera inspection. Our technician arrives in uniform, runs a camera the full length of the flue, and photographs every joint, seam, and surface. You see the images on the screen. We explain what’s wrong, what will happen if it’s left alone, and what we recommend.
- 3
Parts decision - OEM HeatShield or quality aftermarket. If HeatShield OEM parts are available and appropriate, we quote them. If DuraFlex or Gelco offers a better fit for your chimney geometry or fuel type, we explain why. No brand loyalty that isn’t earned.
- 4
The repair or rebuild. Most liner replacements and partial rebuilds finish in one day. Full chimney rebuilds take two to three days. We protect your floors, work clean, and run a final camera pass before we close up.
- 5
Testing and documentation. We pressure-test or smoke-test as appropriate, depending on the job. You get photos, a written report, and the 90-Day Done Right Promise in writing.
- 6
Cleanup and follow-up. We haul away debris. If anything doesn’t look right in the first ninety days, we come back. No paperwork to dig up, no arguing.

Why Easton Homeowners Call Hearthstone Chimney Co. for HeatShield Work
We’ve been in Easton long enough to know which houses have the six-inch flues, which have the abandoned thimbles from old coal conversions, and which neighborhoods see the worst freeze-thaw damage. Russell Haines and our crew have worked on HeatShield products since the brand first gained traction in this market.
Our 90-Day Done Right Promise means if it’s not right, we make it right - in writing, no arguing. Our technicians are background-checked, uniformed, and carry the camera equipment to show you what they see. If HeatShield parts aren’t the best fit, we have DuraFlex and Gelco in our inventory. We’re not a one-brand shop, and we’re not a chain sending whoever’s available that day.
If the flue is clear and the mortar is sound, that’s all the good news you need. If it’s not, we’ll tell you plainly what it’ll take to fix it.
FAQs
Original HeatShield warranties cover defects in materials and original installation; they do not cover normal wear, fuel changes, or damage from chimney fires. As an independent HeatShield service provider, our repairs carry their own 90-Day Done Right Promise. We document everything so you have a record. Call (610) 756-1504 if you want us to review your original paperwork.
Most HeatShield components remain available, though some older ProLiner sizes have been discontinued. When OEM parts are no longer manufactured, we use quality aftermarket equivalents from DuraFlex or Gelco that meet or exceed UL1777 standards. We never install a part we can’t stand behind.
The camera inspection decides it. Localized gaps or single-joint failures often justify repair. Widespread corrosion, multiple seam separations, or a liner undersized for your current appliance usually mean replacement. We’ll show you the images and explain both options. Call (610) 756-1504 for a free inspection.
Most liner repairs and replacements finish in one day. Partial chimney rebuilds take two to three days. Full rebuilds run longer depending on weather and brick matching. We give you a schedule before you commit, and we show up when we say.
Gaps in a liner let heat and combustion gases reach combustible framing - the leading cause of chimney fires. A failed liner can also leak carbon monoxide into living spaces. The risk is real, but we don’t scare-sell. If the damage is minor and your usage is light, we’ll tell you what safe usage looks like and when to schedule. If it’s urgent, we’ll say that too. Call (610) 756-1504 and we’ll give you a straight answer.
