Chimney Repair for Lopatcong chimneys

Lopatcong has more prefab fireplaces than most of Warren County, because so much of its housing was built in the decades when factory-built fireplaces in framed chases became common. Those chimneys fail in their own way: rusted chase covers, loose storm collars and flashing at the chase. Masonry chimneys also appear on many subdivision homes, and the older farmhouses and early-1900s homes have brick stacks in older mortar.

Asset Roofing & Chimney inspects, cleans, repairs, relines and rebuilds chimneys throughout Lopatcong. We replace chase covers, reseal storm collars, rebuild crowns, install caps, repoint and waterproof masonry, rebuild flashing and install stainless-steel liners. We are licensed and insured, and estimates are free.

Lopatcong housing

Most of Lopatcong's homes were built in the second half of the 20th century and after, with a large share of colonials, split-levels and ranches in subdivisions and attached townhouses in planned communities. Older farmhouses and early-1900s homes remain in scattered spots near Phillipsburg and along the rural roads. Asphalt shingle is the norm on residential roofs, prefab fireplaces in framed chases are common, and commercial buildings carry flat or low-slope roofs.

Weather & exposure

Much of Lopatcong sits on open, rolling ground above the Delaware valley, where subdivision homes with young or sparse trees take wind with little to slow it. Cold winters bring snow and freeze-thaw cycling. Large flat commercial roofs collect snow and meltwater, and the river valley below sends fog and damp air up the slopes on cool mornings.

Repair, repoint or rebuild in Lopatcong

If your Lopatcong home has a prefab fireplace, the chase cover and storm collar should be checked every few years. Replacing a rusted cover is a modest job; repairing rotted chase framing after years of leaks is a much larger one. Have the flue cleaned and inspected if you use the fireplace regularly.

For masonry chimneys, a sound crown, a cap on each flue and tight flashing at the roof prevent most problems. We rebuild cracked crowns, repoint open joints, install caps and rebuild flashing, and we apply a breathable water repellent after masonry repairs.

Lopatcong Specifics

Chimney problems we see in Lopatcong

Chase covers that rust and pond

Original sheet-metal chase covers are often flat and thin. They rust, sag, hold water and leak into the framed chase. A replacement cover with a slope and cross-break sheds water and lasts far longer.

Storm collar and flue pipe leaks

On prefab chimneys, the collar where the metal flue exits the chase cover seals against water. When the sealant dries and cracks, rain runs down the outside of the flue pipe into the chase and the firebox.

Hidden rot inside framed chases

Water entering at the top of a chase soaks the framing and sheathing inside long before anything shows on a wall. Swollen siding near the top of the chase or a stain beside the fireplace are the usual first signs.

Crown cracks on masonry chimneys

Masonry chimneys on subdivision homes often have thin mortar crowns that crack after years of freeze-thaw. Water then enters the stack. A rebuilt crown with overhang and a cap stops the problem early.

FAQ

Chimney Repair in Lopatcong: your questions

How do I tell if my chimney is prefab or masonry?

A prefab chimney usually sits in a framed box finished with siding to match the house, with a metal cover and pipe at the top. A masonry chimney is brick or stone all the way up. We confirm the type during inspection, since the repairs are different.

The siding at the top of my chimney chase is swelling. What is wrong?

That is a common sign of water entering at the chase cover or storm collar and soaking the framing. We replace the cover, reseal the collar, open up and repair any damaged framing and sheathing, and check the roof flashing at the base of the chase.

Can a chase cover be replaced without replacing the fireplace?

Yes. The cover is a separate piece. We fabricate or supply a properly sized cover with slope and drip edges, install it with a new storm collar seal, and leave the fireplace and flue in place.

Do townhouse chimneys need separate service from the roof?

They are often serviced together. A townhouse chase or chimney ties into the roof at the flashing, and both need to be sound. We handle the roof and the chimney, which simplifies coordination with the association.
