Chimney Repair · Hillsborough, Somerset County

Chimney Repair in Hillsborough, NJ

Hillsborough's chimneys are mostly younger than those in the older towns of the county, but they have their own problems. The 1980s through 2000s developments overwhelmingly used prefabricated metal fireplaces in sided chases with sheet-metal chase covers, and those covers are now at the age where they rust, sag and leak. Homes with masonry chimneys from the same era often have thin crowns and minimal caps. Older farmhouses have substantial brick chimneys with the crown, joint and liner issues typical of their age.

Wind exposure adds a factor. Chimney caps and chase covers on open Hillsborough lots are more likely to be lifted or torn loose than in sheltered towns. Asset Roofing & Chimney inspects, repairs and replaces chase covers, caps and crowns, repairs flashing, repoints and rebuilds masonry, installs stainless steel liners and waterproofs porous brick.

Repair, repoint or rebuild in Hillsborough

For a prefabricated fireplace we inspect the chase cover, storm collar, cap and the flashing at the roofline, and we look inside the chase from the top where access allows. The usual fix is a new chase cover fabricated with a cross-break so it sheds water, a drip edge that clears the siding, a new storm collar and, if needed, new flashing where the chase meets the roof.

For masonry chimneys the approach is standard: inspect from the roof and inside, rebuild the crown with an overhang and drip edge, repoint open joints, install a mechanically fastened cap that will stay put in wind, correct the flashing and install a liner if the flue is damaged or the appliance has changed.

Hillsborough Specifics

Chimney problems we see in Hillsborough

Rusted and sagging chase covers

Galvanized chase covers from the 1980s and 1990s are reaching the end of their life across the township. Rust-through at the seams and corners, and ponding on flat covers, leak directly onto the fireplace unit below.

Wind-damaged caps and storm collars

On open lots, friction-fit caps and loose storm collars around the metal flue pipe lift and shift in strong wind. Without them, rain enters the flue and the chase.

Chase flashing at the roofline

Where a sided chase passes through the roof, step flashing and a kick-out at the bottom keep water out of the wall. These details were often done minimally on development homes and fail as the original roof ages.

Farmhouse chimneys with old crowns and liners

Older brick chimneys on the surviving farmhouses show cracked crowns, eroded mortar and clay liners that have cracked or shifted. They need the full range of masonry work: crown rebuilds, repointing, caps and liners.

FAQ

Chimney Repair in Hillsborough: your questions

What is a chase cover and why does mine leak?

It is the sheet-metal lid on top of the sided enclosure around a prefabricated fireplace. Original covers were usually galvanized steel, flat, and installed with the seams facing up. After a few decades they rust through or pond water and leak onto the fireplace below. A new cover with a cross-break and a proper drip edge solves the problem for the long term.

My chimney cap keeps blowing off. What kind should I get?

On an open Hillsborough lot, a stainless steel cap that is mechanically fastened to the flue tile or the crown, rather than a friction-fit cap that depends on a tight squeeze, is the right choice. For a prefabricated fireplace, the cap should be the type specified for that unit, secured to the flue pipe with a tight storm collar below it.

Our farmhouse chimney has not been used in years. Does it still need work?

It still takes weather. A cracked crown and open joints let water into the masonry whether or not the flue is used, and that water damages the chimney and can reach the interior. Capping the flue and keeping the crown and joints sound protects the house. If you plan to use it again, it needs an inspection and most likely a liner first.
