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.
Fast, Reliable Chimney Inspection Across North Wales
A chimney inspection in North Wales costs between $189 and $459 depending on the level of inspection and how many flues we’re mapping. Most standard visual inspections in the borough run $189 – $249, and a full Level 2 with camera work runs $299 – $459. If you’re in the old borough grid near Main Street or Walnut Street, your chimney stack may be hiding more than one flue, and that changes everything about how we inspect it. Call (336) 863-3889 and a live person answers. We’ll book you a window, send the technician’s name and photo before we arrive, and put a written price in your hand before any work starts.
Why Alcott Chimney Sweep Is North Wales’s Preferred Chimney Inspection Company
Ruben Castellano started Alcott Chimney Sweep in 2002 with a simple rule: prove who’s coming before the truck pulls up. Every technician who serves North Wales is background-checked, identity-verified, and uniformed under the Threshold Standard. You get their name and photo before the visit, and they show a photo ID at the door. No exceptions. Homeowners in the North Wales borough core, especially those home alone or with young kids, tell us that’s the reason they called us instead of the cheaper option. We serve the whole North Wales area from our Philadelphia dispatch office, with crews working locally in the borough and the Montgomery Township subdivisions every week. Since 2002 we’ve been part of the Threshold Group family, and the Done Right Promise is a full 365 days of accountability on every job we complete.
Fireplace Inspection in North Wales
Fireplace Inspection in North Wales means more than a glance up the flue. In the 1870s – 1910s borough grid around Walnut Street, School Street, and Main Street, a single fireplace flue is often paired with a second flue in the same stack, one that hasn’t been opened or identified in decades. We map what’s actually in the stack before we tell you anything about condition. A fireplace inspection here runs $189 – $249 for a Level 1 visual when the system is accessible and unchanged, and $299 – $399 for a Level 2 when we’re running the camera because of a property sale, a prior chimney fire, or a new insert. We don’t recommend work from a glance; we show you the camera footage or we don’t recommend anything.
When North Wales Fireplaces Need More Than a Look
Shiny black tar deposits on the flue walls mean second-degree creosote, the stage that ignites easily and burns hot enough to crack flue tiles. A brush won’t touch it. We’ll tell you that plainly and show you the footage. North Wales’s freeze-thaw winters also force moisture into old firebrick and mortar, so we’re looking for spalling faces and a rusted damper assembly every time we inspect.
The Camera Doesn’t Guess, and Neither Do We
A Level 2 Chimney Inspection puts a camera down every flue that’s actually in the stack. In North Wales, that’s the step that catches the hidden second flue, the open cleanout, and the misrouted vent before they become a firebox crack or a carbon monoxide path into the house.
Chimney Inspection Services in North Wales
Chimney Inspection Services in North Wales follow the NFPA 211 levels, and we explain exactly which level your property needs before we book. A Level 1 runs $189 – $249 and fits the tract colonials and split-levels in Montgomery Township and Upper Gwynedd, where the zero-clearance fireplace systems are reaching the end of their 20 – 25 year service life. A Level 2 runs $299 – $459 and is what we recommend for any attached twin or rowhome in the old borough core, because shared stacks and converted coal flues are the norm there, not the exception. A Level 3, which involves opening part of the chimney to access concealed areas, runs $500 – $900 and we only recommend it when a Level 2 camera inspection shows a problem we can’t see from the flue side.
Real Estate Inspections for North Wales Buyers
Buying a twin on Main Street or a colonial in Upper Gwynedd? A Level 2 camera inspection before closing is the cheapest insurance you’ll buy. Sellers rarely know the full flue map of a century-old stack. We inspect, we photograph everything, and we deliver a written report you can take to the negotiating table.

Two-Flue Stacks and the North Wales Conversion Problem
Here’s the thing no generic chimney page tells you: in the North Wales borough grid, a single brick stack often carries two flues. One originally served a coal furnace that was converted to gas with no liner installed. One serves a fireplace. The abandoned furnace flue is frequently capped at the thimble and left open to the exterior, so the stack reads as single-flue until a tech is actually on the roof. On a twin along South Main Street, we opened what the homeowner called “one chimney” and found two flues in the same stack: the gas furnace flue unlined from its coal conversion and the fireplace flue packed with second-degree creosote above a rusted damper. We ran a Level 2, dropped a HeatShield liner repair into the furnace flue, brushed the fireplace flue to bare masonry, and sealed the abandoned cleanout that had been funneling freeze-thaw moisture into the smoke chamber. That’s the Alcott difference in North Wales: we inspect what’s actually there, not what the stack looks like from the ground.

That means Olympia Chimney stainless liner components, Famco caps and terminations, Copperfield dampers, and DuraFlex liner systems for the converted coal flues in the old borough grid. Not box-store substitutes. When a North Wales homeowner needs a repair after inspection, parts are sourced through the same distribution channels chimney professionals use, so turnaround is measured in days, not weeks. And every repair gets a written guarantee: if it fails within the coverage period, the second visit is free.
Common Chimney Inspection Problems We See in North Wales Homes
- Coal-conversion flues with no liner. The old furnace flue is undersized for a modern gas appliance and was never lined when the coal unit came out. Acidic gas exhaust eats the interior mortar, and the flue gases can migrate through the brick into the house.
- Open abandoned cleanouts wicking moisture. That old cast-iron cleanout in the cellar wall is a direct channel for freeze-thaw moisture to get inside the chimney breast. We see this constantly in the 1870s – 1910s borough homes, and it spalls mortar from the inside out.
- Shared stacks between attached twins. In North Wales, your right-hand neighbor’s furnace may vent into the same stack you assume is yours alone. Cross-contamination goes undiagnosed until a Level 2 camera inspection maps each flue’s actual termination point.
- Factory-built fireplace systems at end of life. The 1960s – 1990s tract homes in Montgomery Township and Upper Gwynedd have zero-clearance metal flue systems now past their 20 – 25 year service window. We inspect for warped panels, rusted seams, and separation at the joints.

FAQs About Chimney Inspection in North Wales
You need a Level 2 camera inspection that maps each flue’s actual termination point. In attached North Wales twins, the shared stack often contains two or even three flues, and the only way to confirm which appliance vents where is to run a camera through each channel and trace it visually. We do this every week in the borough core. If we find cross-ventilation or the neighbor’s flue gases entering your side, we’ll show you the footage and give you a written repair scope. Call (336) 863-3889 to book a Level 2.
Because it was built for a coal furnace, not a gas one. The borough grid’s chimneys from the 1870s through 1910s were engineered for coal combustion, which runs hotter and drafts differently than modern gas. When the coal furnace came out, the flue was reused without relining, leaving a channel that’s undersized for the appliance now connected to it. The fix is a properly sized liner system, typically DuraFlex or HeatShield, which we install and warranty in writing. Call (336) 863-3889 for a flue sizing assessment.
An abandoned coal-conversion cleanout, almost certainly. The old furnace cleanout in the cellar wall was left open when the coal unit was removed, creating a direct channel for freeze-thaw moisture to enter the chimney mass from inside. We see this in North Wales borough homes constantly, and it spalls mortar from the inside out. We locate it, seal it, and repair any moisture damage we find. Call (336) 863-3889 and we’ll find it.
Annually, without exception. Southeastern Pennsylvania’s alternating freeze-thaw cycles are brutal on the soft, century-old mortar in North Wales borough chimneys. Each winter, moisture gets into the joints, freezes, expands, and opens the mortar wider; every Nor’easter drives wind-driven rain horizontally into deteriorated crowns and flue tops. An annual inspection catches spalling and water intrusion before you’re paying for a rebuild. Call (336) 863-3889 to get on the schedule.
That’s second-degree creosote, the tar-like glaze that ignites at a lower temperature and burns hotter than the powdery first-degree kind. A standard brush won’t remove it. It requires chemical treatment or mechanical removal with a rotary chain head, and in some cases a HeatShield resurfacing after we get it off. We’ll show you the camera footage before recommending anything. Call (336) 863-3889 and we’ll assess it.
