Chimney Repair in Andover Borough, NJ | Monarch Roofing & Construction

Andover Borough is a small village of about 600 residents on roughly a square and a third mile in Sussex County, surrounded by Andover Township and bordering Byram and Green. It was carved out of Andover Township in 1904, but its story starts much earlier with the Iron Works at Andover, a forge and furnace complex that included housing for its workers. The Andover Borough Historic District preserves the forge, furnace, and workers’ housing area, along with landmarks such as the Iron Master’s Mansion on Main Street and the Grist Mill Stone House of 1760. With only about 260 homes, many of them older, chimney work here calls for patience and care.

Monarch Roofing & Construction repairs chimneys for Andover Borough homeowners. We focus on the exterior of the chimney and the roof around it: flashing, brick and stone masonry, crowns, caps, and rebuilding above the roofline. Every job begins with a free chimney repair estimate.

Where Old Meets Newer Masonry

Houses that have stood for a century or more have usually been re-roofed many times, and their chimneys have often been repaired in stages. A common pattern is a chimney that was rebuilt above the roofline at some point but not below it. That leaves a transition where newer masonry sits on older masonry, often right at or just below the roof.

Why the Transition Matters

The newer section may be built with harder mortar or different brick than the original below. The two parts can weather differently, and the joint between them is a place where cracks and gaps form. Because the transition is often hidden by the flashing or sits in the attic, it is easy to miss.

What We Look For

From the roof, we look at how the newer and older sections line up, whether the joint between them is open, and whether the flashing is set into sound mortar. If the attic is accessible, we look at the portion of the chimney that passes through it for damp masonry, loose brick, or crumbling joints.

How We Address It

Where the transition is sound, we make sure flashing and mortar joints around it are tight. Where it has opened up, we repoint or relay the affected courses with compatible mortar. If the older masonry below the roofline is deteriorating, we explain what we see so you can decide how to proceed.

Stone and Masonry Walls

Andover’s early buildings include stone construction, and some roofs meet stone walls or stone chimneys. Stone surfaces are irregular, so flashing cannot simply be tucked into straight mortar joints the way it is on brick. Counter flashing must be carefully scribed or cut into the stone joints so it lies tight against the uneven surface. Mortar for stone should be compatible with the stone and the original mortar. We take the time to detail these joints so water stays out.

A Maintenance Rhythm for Older Chimneys

Older chimneys last longest when small problems are handled before they spread. Twice a year, in spring and fall, look at the chimney from the ground with binoculars. Check that the cap is in place, the crown has no obvious cracks, the mortar joints look full, and the flashing lies flat without fresh tar. After heavy storms, look again for anything that has shifted. Inside, check ceilings and walls near the chimney after long rains or snowmelt. When you notice a change, schedule an estimate so we can address it while the repair is still modest. This kind of steady attention is especially valuable for masonry that has already weathered many decades.

Historic District Considerations

Because the borough has a recognized historic district, owners of older properties should ask the borough whether any review applies before changing the visible appearance of a chimney or roof. When you tell us what is required, we plan the work to that specification.

Flashing on Brick Chimneys

A complete flashing system includes step flashing woven into each shingle course along the sides, counter flashing set into a groove cut in the mortar joints, apron flashing on the downhill face, and a cricket or back pan behind wider chimneys. On older roofs, we remove old tar and metal, check the board sheathing for rot, and install new flashing with leak barrier and underlayment.

Brick and Mortar

Repointing removes deteriorated mortar to a consistent depth and refills the joints with fresh mortar compatible with the brick or stone. Older masonry generally calls for softer mortar so that joints, not bricks, take the weathering. Spalled or cracked bricks are replaced with matching units.

Rebuilding

When a chimney leans, has loose brick near the top, or has mortar failing throughout, a rebuild may be needed. A partial rebuild takes the chimney down to sound masonry and relays it. A full rebuild above the roofline replaces all exposed masonry. We document the chimney first so details can be matched. Both include new flashing, a crown, and a cap. We recommend rebuilding only after an evaluation.

Crowns and Caps

The crown should slope away from the flue and overhang the masonry so water drips clear. Older crowns are often thin and cracked. We seal minor cracks and replace failed crowns. Caps keep rain, snow, leaves, and animals out of the flue.

Waterproofing After Repairs

After repairs, once the mortar has cured, a breathable water repellent can reduce how much water sound masonry absorbs while still letting it dry. It is protection, not a repair, and will not stop leaks from flashing, open joints, or a cracked crown. Nonbreathable coatings can trap moisture in older masonry, so we avoid them.

Snow and Freeze-Thaw

Sussex County winters bring snow and repeated freeze-thaw cycles. Water in masonry freezes and expands, breaking it down from the top, and snow behind a chimney keeps the back flashing wet. Sound joints, a good crown, a cap, and complete flashing protect the chimney.

Signs Your Chimney Needs Repair

• Stains near the chimney on ceilings or walls
• Damp masonry where the chimney passes through the attic
• Crumbling or recessed mortar
• A visible line or gap where newer masonry meets older
• Flaking or cracked brick
• A cracked crown or missing cap
• Tar-patched flashing
• A leaning chimney

Repair Versus Rebuild

Most chimneys can be repaired with flashing, repointing, brick replacement, and crown work. Rebuilding makes sense when damage is widespread or the chimney is structurally unsound. We explain what we find.

What Affects the Cost

We do not quote prices without seeing the chimney. Cost depends on height and size, whether it is brick or stone, roof pitch, how much mortar and masonry work is needed, crown and flashing condition, sheathing repairs, matching requirements, and whether a rebuild is needed.

Permits for Chimney Work in Andover Borough

Permit requirements depend on the type of chimney work. Rebuilding a chimney or other structural masonry work may require a construction permit and inspection under New Jersey’s Uniform Construction Code, while some minor exterior maintenance may not. Because the answer depends on the scope of the job, check with the Andover Borough construction office before work begins, and we can discuss it during your estimate.
