Chimney Repair for Andover chimneys

Andover Borough's older houses mostly have brick chimneys that were built long before stainless liners or modern crowns. Many served wood or coal heat, then oil, then gas, and some now vent a furnace or water heater through a flue that was never sized for it. Outside, generations of Sussex County winters have worn the mortar and cracked the crowns.

Asset Roofing & Chimney inspects, cleans, repoints, rebuilds and relines chimneys in Andover. We rebuild crowns, install caps and chase covers, repair flashing, waterproof masonry and install liners sized to the appliance the chimney actually serves. We are licensed and insured, and estimates are free.

Andover housing

Andover's housing is mostly older village stock: 19th-century and early-1900s farmhouse-style homes, gabled houses with porches, and buildings along Route 206 that mix residential and commercial use. Many have steep gable roofs with asphalt shingles laid over older roofs, low-slope porch and rear-addition roofs, and brick chimneys that predate modern liners. Some later homes sit at the edges of the borough.

Weather & exposure

The borough sits in the valley along Route 206 rather than on an exposed ridge, so its roofs are somewhat sheltered from wind, but it shares Sussex County's cold winters, heavy snow and long freeze-thaw season. Mature trees overhang many older lots, and road spray and salt along the highway corridor add wear to buildings close to the road.

Repair, repoint or rebuild in Andover

If your Andover home has an older brick chimney, start with an inspection that covers both the outside and the inside of the flue. The crown, joints and flashing tell us how water is getting in, and the flue tells us whether the chimney is safe for the fireplace, stove or furnace attached to it.

Most chimneys here can be saved with repointing, a new crown, a cap and a breathable water repellent. If the top courses are loose or the stack is leaning, we rebuild from a sound course upward. Interior work usually means a stainless-steel liner sized to the appliance.

Andover Specifics

Chimney problems we see in Andover

Flues repurposed from older fuels

A chimney that once served a coal or oil furnace may now vent a gas appliance or sit unused. Oversized or unlined flues let acidic condensation attack the mortar from the inside. A liner sized to the current appliance fixes that.

Eroded joints in old brick

Older mortar is softer than modern mixes and washes out under freeze-thaw. Open joints near the top of the stack let water in, and the damage works downward each winter. Repointing with a compatible mortar is the repair.

Crowns that are just a mortar wash

Many older chimneys were topped with a thin layer of mortar instead of a formed crown. It cracks quickly and sheds water onto the brick. A rebuilt crown with an overhang keeps water off the face of the chimney.

Uncapped flues

Older chimneys are frequently uncapped, letting in rain, snow, leaves and animals. A sized, secured cap protects the flue and damper and is one of the simplest improvements on an older home.

FAQ

Chimney Repair in Andover: your questions

Does an unused chimney on an older house still need maintenance?

Yes. Even a chimney that is never used takes on water through the crown and joints, and that water damages the masonry and can leak into the house. A cap, a sound crown and tight flashing keep an unused chimney from becoming a problem.

Can my gas furnace safely vent into the old chimney?

It depends on the flue size and condition. Older flues are often too large for a modern gas appliance, which leads to condensation damage and poor draft. We inspect the flue and, if needed, install a liner sized for the appliance.

What kind of mortar do you use on old brick?

We match the mortar to the brick. Older, softer brick should be repointed with a mortar that is not harder than the brick itself, so the joints, not the brick faces, take the stress of freeze-thaw.

Can you fix the leak where my chimney meets the roof?

Yes. We are roofers as well as chimney contractors, so we replace caulked or worn flashing with properly stepped and counter-flashed metal that is integrated with the shingles.
