Chimney Repair for Union chimneys

Union Township chimneys deal with elevation and wood smoke. Ridge-top chimneys take wind that strips caps and drives rain into the masonry, and lasting snow and frequent freeze-thaw crack crowns and loosen joints. Many homes burn wood for heat, so flues build creosote and stoves are often connected to chimneys built for open fireplaces. Older farmhouses have brick or stone stacks in soft mortar.

Asset Roofing & Chimney inspects, cleans, repairs, relines and rebuilds chimneys throughout Union Township. We install fastened caps, rebuild crowns, repoint and waterproof masonry, replace chase covers, rebuild flashing and install stainless-steel liners for stoves, inserts and heating appliances. We are licensed and insured, and estimates are free.

Union housing

Union Township's housing is mostly detached homes: older farmhouses and village homes, and ranches, capes, split-levels and colonials built from the mid-1900s onward on rural and semi-rural lots. Some commercial and service buildings near the highway have flat or low-slope roofs. Asphalt shingle dominates on houses, with metal on some barns and outbuildings. Wood stoves and fireplaces are common.

Weather & exposure

Elevation and open ridges define Union Township's weather exposure. Homes on the ridges and hilltops take strong wind, and storms crossing the reservoir and the open highway corridor arrive with little to slow them. Snow lasts longer on the higher ground, freeze-thaw is frequent, and wooded lots add limbs and leaf litter.

Repair, repoint or rebuild in Union

On exposed chimneys, start with a cap mechanically fastened to the flue or crown, a crown with a proper overhang and sound mortar. A breathable water repellent after repairs slows freeze-thaw damage.

If you heat with wood, have the flue inspected and cleaned every year before the heating season, and make sure any stove or insert vents through a properly sized liner. We check the roof flashing at the chimney whenever we work on it.

Union Specifics

Chimney problems we see in Union

Caps blown off exposed chimneys

Friction-fit caps do not stay on ridge-top chimneys. Without one, rain and snow enter the flue and animals can nest inside.

Crowns cracked by long winters

Lasting snow and frequent freeze-thaw crack thin crowns, letting water into the top of the stack and loosening the upper courses.

Stoves in unlined fireplace flues

A stove venting into a large fireplace flue drafts poorly and builds creosote quickly. A liner sized to the stove corrects both problems.

Eroded mortar on farmhouse stacks

Old brick and stone chimneys laid in soft mortar lose their joints to weather. Repointing with a compatible mortar stops water before the stack needs rebuilding.

FAQ

Chimney Repair in Union: your questions

Why does my chimney cap keep blowing off?

Chimneys on high, open ground take wind that a standard cap cannot resist. We install caps sized to the flue and fastened securely, and we check the crown underneath.

How often should I clean my wood stove chimney?

At least once a year, and more often if wood is your main heat. We clean the flue, inspect the liner and check the cap and crown at the same visit.

Can I put a wood stove in my old fireplace?

Yes, with a stainless-steel liner sized to the stove and run the full height of the chimney. We inspect the chimney first and recommend the right liner.

My chimney crown is cracked. Is that a big deal?

It lets water into the top of the chimney, where freeze-thaw does steady damage. Rebuilding the crown with a proper overhang is one of the most cost-effective chimney repairs.
