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.

AfterHeatShield Chimney Cap & Crown in Bedford: What to Know First
We provide independent HeatShield chimney cap and crown service in Bedford, with most calls scheduled within a few days and straightforward pricing agreed before we start. A typical HeatShield cap replacement runs $340-$620, crown coating $480-$890, and we do not recommend work you cannot see for yourself. This page is for Bedford homeowners who already have HeatShield components on their chimney and want a technician who knows the difference between a Series 200 multi-flue cap and a ProForm crown coating without being talked into a full rebuild. Call (914) 409-9387 and a live person will pick up, any hour.
How HeatShield Products Fail - and How We Fix Them
- Series 200 stainless multi-flue caps: The corner welds on early-production units through roughly 2018 tend to crack where the lid meets the skirt, especially on Bedford chimneys that see heavy freeze-thaw cycling off the reservoir. Water gets in, rusts the mesh, and suddenly you’ve got squirrels in the flue. We source the matching gauge 304 stainless skirt sections or fit a Gelco equivalent with the same mesh count if HeatShield lead times stretch past two weeks.
- ProForm crown coating delamination: When applied over a crown that was not properly prepped, ProForm separates in sheets after three to five winters. In the stone-and-timber colonials near Bedford Village, we see this where the original crown had hairline cracks that were caulked instead of ground out. We strip to sound concrete, treat with ProForm’s specified bonding agent, and reapply to the 3/8-inch minimum thickness the product requires.
- Single-flue galvanized caps (discontinued line):strong> HeatShield stopped offering these around 2015, but plenty remain on Bedford’s 1970s and 1980s builds. The galvanized coating fails from the inside out, starting at the fastener holes where condensation pools. We replace with 304 or 316 stainless depending on flue gas chemistry, never reusing the original clamp bands if they’ve started pitting.
- ProForm crown coating over expansion joints: Original builders sometimes omitted control joints in poured concrete crowns. ProForm applied directly over a monolithic crown will telegraph every crack within two seasons because the substrate keeps moving. We cut relief joints with a diamond blade before coating, or recommend a full crown pour if the slab is less than two inches thick at the drip edge.
- Custom copper cap tarnish-through on coastal-exposed flues: Bedford’s not coastal, but the microclimate on north-facing chimneys above the reservoir fog line behaves similarly. HeatShield’s custom copper line develops pinholes where the solder meets the seam, not from the copper itself but from galvanic reaction with the stainless spark arrestor. We spot-repair with copper-only fasteners and dielectric separation, or transition to a Gelco copper-look stainless cap if the owner wants the aesthetic without the maintenance cycle.
Our HeatShield Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, checks our calendar, and books a window. We ask whether you know your HeatShield model or can text a photo of the cap tag.
- 2
Level-2 camera inspection. Our tech documents the crown surface, cap fit, and flue condition with photos you see on the tablet. No verdict until you’ve seen what we’ve seen.
- 3
Parts decision. If your HeatShield part is in stock, we quote OEM. If HeatShield’s warehouse is backordered, we quote a DuraFlex or Gelco equivalent that matches the spec, with the trade-off explained in plain English. You choose.
- 4
Repair or replacement. Crown work gets ground, bonded, and coated to ProForm spec. Cap work gets proper overlap, storm collar sealing, and mesh secured with stainless hardware. Most jobs finish in one visit.
- 5
Post-repair test and documentation. We run a final camera pass, verify draft and cap clearance, and email you the photo report with the 90-Day Done Right Promise in writing.
- 6
Cleanup and walkthrough. We leave the roof and yard as we found them, explain what we did, and answer questions before the invoice. The number on the estimate is the number on the invoice.
What HeatShield Chimney Cap & Crown Costs in Bedford

|---|---|---|
| Series 200 cap replacement | $340-$620 | Flue count, mesh gauge, roof access difficulty |
| Single-flue stainless cap (new or upgrade) | $280-$490 | Flue shape, clamp vs. bolt-on, brand |

Bedford’s freeze-thaw severity and the older masonry common in Katonah and Bedford Hills mean we often find more prep work than the cap price alone suggests. We price it upfront, not as a surprise mid-job. Call (914) 409-9387 for an exact quote - estimates are free.

FAQs
Does using Hearthstone Chimney Co. void my HeatShield warranty?
No. As an independent HeatShield service provider, we follow OEM installation specs and use factory-specified materials, which preserves any remaining warranty coverage. We document our work with photos in case you ever need to file a claim. Call (914) 409-9387 for an exact quote - estimates are free.
How long does a HeatShield cap replacement take?
Most single-flue or standard multi-flue replacements finish in two to three hours from ladder set to cleanup. Custom fabrication or crown rebuilds that must precede cap installation can extend to a full day. We give you a time estimate when we quote, not a vague window. Call (914) 409-9387 for an exact quote - estimates are free.
Can you get HeatShield parts, or do you use generics?
We source OEM HeatShield when lead times are reasonable, which they usually are for standard caps. For discontinued lines or backordered items, we quote DuraFlex or Gelco equivalents that match the spec - never a downgrade without your okay. You see the part before it goes on. Call (914) 409-9387 for an exact quote - estimates are free.
My crown has cracks but the cap looks fine. Do I need both?
Not necessarily. A cracked crown with intact cap can often be coated with ProForm if the concrete is sound underneath. We camera-inspect and probe to verify, then show you the photos. If the crown is spalling or less than two inches thick, we recommend pouring new before capping. Call (914) 409-9387 for an exact quote - estimates are free.
How often should a HeatShield cap and crown be inspected?
Annual inspection is the standard for any chimney system in Bedford’s climate. HeatShield stainless caps hold up well but the crown coating and fasteners still need eyes on them before burning season. Our $89 Seasonal Tune-Up includes cap, crown, and flue check with photo documentation. Call (914) 409-9387 for an exact quote - estimates are free.
