Chimney and fireplace service for Woodstock homes
Woodstock has some of the oldest housing stock in our service area, which means genuine period masonry chimneys — beautiful, but decades past their last repointing in many cases. Deteriorated crowns, spalling brick, and cracked clay liners are common, and all are work we do.
- Chimney sweeping — creosote and soot removed with the fireplace sealed and a HEPA vacuum running
- Inspection — Level 1 and Level 2, including camera scans for home sales
- Repair and masonry — tuckpointing, brick, flashing, and waterproofing
- Relining — stainless liners sized to the appliance
- Caps and crowns — the cheapest protection against water damage
- Gas fireplace service, dryer vent cleaning, and air duct cleaning
Local to Woodstock
The Woodstock Square Historic District, on the National Register since 1982, is anchored by the Old McHenry County Courthouse and the Woodstock Opera House, its brick streets squaring off a park with two gazebos. The historic homes radiating out from the Square are exactly the kind of older masonry chimneys that need careful, matched repair.
Families across Woodstock — including students at Woodstock High School — count on a chimney that works safely all winter. Century-old masonry plus decades of freeze-thaw is the defining chimney challenge in Woodstock — water works into aged mortar and pries it apart every winter, so repointing and crown protection matter enormously here.

Frequently Asked Questions
Do you work on the historic homes around the Woodstock Square?
Yes. The older homes near the Square have genuine period masonry chimneys, and we handle careful tuckpointing, crown repair, and relining while matching materials as closely as possible.
My Woodstock chimney has crumbling mortar. What does that need?
That is failed mortar, and it needs tuckpointing — grinding out the old joints to a sound depth and repointing with matched mortar. Done properly it restores the weather seal and the structural bond.
Can you match old brick on a historic Woodstock home?
As closely as available materials allow, in color and joint profile. On very old brick an exact match is not always possible, but a careful blend usually reads as original from the ground.
Is a very old clay liner still safe?
Not always. Old clay liners crack and their mortar joints wash out over decades. A camera inspection tells us the truth, and relining restores safety if the liner has failed.
Do you inspect chimneys for Woodstock home sales?
Yes, Level 2 inspections with camera scans and written documentation.
Do you charge travel to Woodstock?
No. Published prices apply in Woodstock with no travel fee.
Are you available on weekends in Woodstock?
Yes, 7am to 7pm every day.
How urgent is a leaning or badly cracked chimney?
Treat it as urgent. On older Woodstock homes, structural cracks or a lean can mean the stack is failing. Stop using the fireplace and have it looked at promptly.
