Chimney Repair for Knowlton chimneys

Knowlton chimneys work hard. Wood stoves and fireplaces are a real heat source in much of the township, and the masonry has to stand up to months of firing on the inside and river-valley wind, damp air and freeze-thaw on the outside. The village homes and farmhouses have old brick chimneys laid in soft lime mortar, while later rural homes have masonry fireplaces with modern mortar or prefab units in framed chases.

Asset Roofing & Chimney inspects, cleans, repairs, relines and rebuilds chimneys throughout Knowlton. We rebuild crowns, install caps, repoint and waterproof masonry, replace chase covers, rebuild flashing and install stainless-steel liners sized to stoves, inserts and fireplaces. We are licensed and insured, and estimates are free.

Knowlton housing

Knowlton's housing is spread thin across a large rural township. The river villages hold 1800s and early-1900s frame homes with steep roofs, porches and old brick chimneys, while the farms carry farmhouses and outbuildings of similar age. Later homes from the 1960s onward sit on large lots along the rural roads, mostly with asphalt shingle roofs. Some farm buildings and custom homes have standing-seam metal. Wood heat is common throughout.

Weather & exposure

The Delaware River corridor and the Water Gap funnel wind along the valley, and the open hillsides above it have little shelter. River fog and damp air settle in the low ground near the Delaware and Paulins Kill, while the higher ground near the Kittatinny Ridge holds snow longer. Winters are long and cold, and wooded lots add shade, moss and falling limbs in summer storms.

Repair, repoint or rebuild in Knowlton

If you burn wood in Knowlton, an annual inspection and cleaning before the heating season is basic maintenance, and heavy burning may call for more. Confirm that any stove or insert vents through a liner sized to it. A chimney that has had a fire, or one with cracked clay tiles, should not be used until it has been inspected and relined if needed.

Outside, the order of priority is stopping water. That means a sound crown with an overhang, a cap on every flue, repointed joints and flashing that is properly let into the masonry. On older chimneys we use mortar suited to soft historic brick, then apply a breathable water repellent once the repairs have cured.

Knowlton Specifics

Chimney problems we see in Knowlton

Wood stoves vented into oversized flues

A stove or insert connected to a large old fireplace flue runs cool, drafts poorly and builds creosote fast. A stainless-steel liner sized to the stove outlet corrects all three and is one of the most useful upgrades for a wood-heated home.

Soft mortar on century-old stacks

Village and farmhouse chimneys were laid in lime mortar that washes out over many winters. Joints recess, the upper courses loosen and water soaks into the stack. Repointing with a compatible mortar stops the decline before a rebuild is needed.

Water entering through an uncapped flue

Many older chimneys still have open flues. Rain and snow fall straight in, rusting dampers and soaking the smoke chamber, and birds and animals move in. A properly fastened cap is a small fix that protects everything below it.

Damp masonry near the river

Chimneys in the low ground by the Delaware and Paulins Kill dry slowly after rain. Brick that stays wet through freeze-thaw spalls, beginning near the crown and on the weather side. Waterproofing after repairs helps the masonry shed water.

FAQ

Chimney Repair in Knowlton: your questions

I just installed a wood stove insert in my old fireplace. Does it need a liner?

Yes. An insert venting into a large masonry flue without a liner will draft poorly and deposit creosote quickly. A stainless-steel liner sized to the insert outlet runs from the stove to the top of the chimney and gives you a safe, efficient flue.

Why does my fireplace smell musty in summer?

Usually because rain is getting into the flue through a missing cap or a cracked crown and mixing with creosote and soot. A cap, crown repair and cleaning typically solve it. We inspect to confirm the source.

Can an old farmhouse chimney be saved, or does it need rebuilding?

If the brick is sound and the stack is straight, repointing, a new crown and a cap are usually enough. If the top courses are loose, faces are spalling badly or the chimney leans, a partial rebuild from a sound course up is the lasting repair. We explain which applies after the inspection.

Do you repair the flashing around the chimney too?

Yes. We are roofers as well as chimney contractors, so we rebuild step and counter flashing in new metal and tie it into the roof. On older homes the flashing is often the real source of a leak that gets blamed on the chimney.
