Chimney Repair in Long Hill Township, NJ | Monarch Roofing & Construction

Long Hill Township is bounded by water on three sides: the Passaic River along its southern and western edges and the Great Swamp National Wildlife Refuge to the north. Its communities, Gillette, Stirling, Millington, Meyersville, and Homestead Park, share humid air and plenty of shade from mature trees. For a masonry chimney, that means brick and mortar that stay damp after every rain, which leaves them more exposed to the freeze-thaw cycles that crack crowns, erode joints, and flake brick faces.

Monarch Roofing & Construction repairs chimneys throughout Long Hill Township. We find out how water is getting into the chimney and stop it, whether that means new flashing, repointed mortar, a new crown and cap, or rebuilding the masonry above the roofline. Every job starts with a free chimney repair estimate.

Reading the Signs of Water in a Chimney

A chimney usually shows signs of moisture trouble before a leak appears inside. Knowing what they mean helps you act early:

White staining on the brick (efflorescence). As water moves through masonry, it dissolves salts and leaves them on the surface when it evaporates. Efflorescence means water is traveling through the chimney.
Flaking or popping brick faces (spalling). Water inside the brick has frozen and broken off the surface.
Moss or dark, damp patches. The brick is staying wet, often on a shaded face.
Recessed or sandy mortar. The joints are eroding and letting water in.
Stains on the ceiling or in the attic near the chimney. Water has made it all the way through, often at the flashing.
A musty smell in the attic near the chimney. Moisture is collecting around the chimney framing.

Each of these points to where water is entering, and that guides the repair.

Where Water Gets In

From the top

Rain and snow can enter through a cracked crown or an uncapped flue. Water that gets into the top of the chimney soaks down through the masonry and shows up as efflorescence and spalling on the upper courses. A sound crown and a cap stop it.

Through the sides

Eroded mortar joints and porous brick let wind-driven rain soak into the chimney. Repointing restores the joints, and a breathable water repellent applied after repairs can reduce absorption through the brick.

At the roof line

Failed flashing is the most common source of chimney leaks into the house. Corroded step flashing, counter-flashing pulled out of eroded joints, or joints sealed only with roofing cement all let water run into the attic. New flashing installed in layers with the shingles solves it.

Flashing Repair and Replacement

Correct flashing combines step flashing woven into each course of shingles along the sides, counter-flashing set into a cut in the mortar and folded down over the step flashing, an apron across the low side, and a back pan or cricket across the high side. We remove failed flashing, check the decking underneath for moisture damage, and install new metal in the correct sequence. Because we are roofers, we also repair the surrounding shingles so the chimney and roof shed water together.

Repointing and Brick Replacement

Repointing removes deteriorated mortar to a sound depth and replaces it with fresh mortar compatible with your brick, tooled to match the existing joints. Compatible mortar is important: if it is harder than the brick, the brick takes the stress and can crack.

Cracked and spalled bricks are cut out and replaced. Because spalling is a moisture symptom, we always look for its source at the same time.

Crowns and Caps

A crown should be a solid, sloped slab that overhangs the brick with a drip edge so water falls clear. Thin mortar crowns crack quickly. We repair minor cracks and replace failing crowns.

A cap keeps rain, snow, animals, and leaves out of the flue. We install caps where missing and replace damaged ones. Screened caps help on wooded lots.

Shade, Trees, and Drying Time

How quickly a chimney dries after rain has a lot to do with how long it lasts. A chimney in full sun and open air may dry within hours. One shaded by tall trees on a humid day near the river or the swamp may stay damp for days. The longer the masonry holds water, the more chances freezing weather has to damage it.

You can help by trimming back branches that overhang the chimney, which lets sun and air reach the brick and reduces the leaves and debris that collect behind it. Combined with a sound crown, a cap, and tight mortar joints, better drying conditions noticeably slow the wear on a chimney.

Rebuilding Above the Roofline

When moisture damage has loosened brick across many courses, the chimney leans, or patching has left little sound masonry, rebuilding may be the right choice. A partial rebuild replaces the upper courses; a full rebuild replaces everything above the roofline. Each includes a new crown, cap, and flashing. We recommend rebuilding only after evaluating the chimney.

Breathable Waterproofing

In a humid setting between the river and the swamp, a breathable water repellent can be a useful last step after repairs. It reduces how much liquid water the brick absorbs while allowing vapor to escape. Non-breathable coatings can trap moisture and make spalling worse. A repellent never substitutes for repairing flashing, crowns, or mortar.

Repair Versus Rebuilding

When the masonry is mostly sound, repair is the practical choice. When deterioration runs through many courses or the chimney has shifted, rebuilding lasts longer. We explain what we found and why we recommend one approach.

Permits for Chimney Work

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 Long Hill Township construction office before work begins, and we can discuss it during your estimate.

How do I schedule?

Use the scheduling button on this page or call or text (551) 241-0470.

What does white staining on my chimney mean?

It is efflorescence, a sign water is moving through the masonry. The source is usually the crown, cap, mortar, or flashing.

Can moss damage my chimney?

Moss holds moisture against the brick and is a sign the masonry stays wet. Keeping water out is the main fix.

Should I seal my chimney because of the humidity?

Only with a breathable repellent, and only after repairs. Non-breathable sealers can trap moisture.

Why does my attic smell musty near the chimney?

Moisture may be getting in around the chimney, often through the flashing. It is worth having it checked.
