Chimney Repair for Clark chimneys

Most chimneys in Clark are brick stacks from the 1950s and 1960s, usually serving a furnace or water heater and often a fireplace. They are short to medium in height on low roofs, which keeps them reachable, but sixty-plus years of freeze-thaw has cracked many original crowns and opened mortar joints near the top.

We repair chimneys throughout the township: crowns, caps, repointing, flashing, stainless steel liners, rebuilds of deteriorated upper courses, waterproofing and cleaning. Every inspection covers the flue interior as well as the exterior, with photos of what we find.

Many Clark homes have replaced their original oil or gas equipment with newer, more efficient appliances. If the new furnace or water heater still vents into the original clay flue, the flue may now be too large, and condensation can damage it from the inside.

Clark housing

Clark's housing stock is dominated by post-war ranches, split-levels, capes and modest colonials built mostly in the 1950s and 1960s, many since expanded with second-story additions, rear extensions and dormers. Roofs are generally simple gables and hips with low to moderate pitches. Brick chimneys serving a furnace and fireplace are common. Shopping centers, office buildings and light commercial properties along the main roads and near the Parkway carry flat roofs.

Weather & exposure

Clark is low and gently rolling with moderate wind exposure and a mix of mature and younger street trees. Low-pitched ranch and split-level roofs hold snow and form ice dams at the eaves in cold stretches, and nor'easters push rain sideways into flashing. Areas near the reservoir and the river branch stay damper. Summer thunderstorms bring wind gusts that lift aged shingle tabs.

Repair, repoint or rebuild in Clark

An inspection shows what the chimney needs. On most Clark chimneys that is some combination of a crown, cap, repointing at the top and a liner if appliances have been updated. Where the upper courses are loose or badly spalled, we rebuild from the roofline up. You get photos and a written scope.

If you are replacing the roof, have the chimney looked at first. Flashing and masonry repairs are simplest when the roof is open.

Clark Specifics

Chimney problems we see in Clark

Original mortar-wash crowns

Thin crowns troweled on when the house was built crack and let water into the brick core. We pour new reinforced crowns with an overhang and drip edge so water is shed clear of the brick.

Flashing on low roofs

On a shallow roof, water and snow sit against the chimney longer. Worn step flashing and caulk-patched counterflashing leak readily. We install new flashing cut into the mortar joints so it does not rely on sealant.

Liners for updated heating systems

Newer furnaces and water heaters often produce cooler exhaust that condenses in a large clay flue. We install stainless steel liners sized to the appliance to protect the masonry and restore draft.

Open joints at the top courses

Mortar near the top of the stack washes out first. We rake and repoint with matched mortar while the brick is still sound, which is far cheaper than rebuilding later.

Uncapped flues

Open flues take in rain, birds and squirrels. We fit stainless caps sized to each flue, which also keeps water off the smoke shelf and out of the furnace connection.

FAQ

Chimney Repair in Clark: your questions

We got a new high-efficiency furnace. Does that affect the chimney?

It can. Many high-efficiency furnaces vent through a plastic pipe and no longer use the chimney at all, but a water heater may still vent into it alone, which can leave the flue oversized. Mid-efficiency appliances that do use the chimney often need a liner. We inspect and tell you what the venting needs.

Is a cracked crown urgent?

It is worth fixing before winter. Water entering through the crack freezes and widens it, and gets into the brick and mortar below. A crown replacement is a modest job compared with rebuilding the top of a chimney that has been saturated for years.

Why does water show up near the chimney only in winter?

On low-pitched roofs, snow and ice build up against the uphill side of the chimney and melt slowly, which tests the flashing more than rain does. Worn or sealant-dependent flashing leaks under those conditions. New metal flashing, and a cricket on wider chimneys, solves it.

Do you clean chimneys as well as repair them?

Yes. We clean fireplace and appliance flues and inspect them at the same time, so you know the condition of the liner as well as the exterior.
