Since 1947
A. Pennacchi and Sons is a licensed masonry contractor specializing in chimney repair, and our shop has sat on Buttonwood Street in Hamilton since 1947. We are not a crew driving in from out of town. We are Hamilton Township neighbors, and chimney masonry has been the family craft the whole time. Four generations of the Pennacchi family have run this business, and Paul Pennacchi Jr. now leads every chimney restoration project, often a few minutes from our own front door. Our roots go back to the 1930s, when Gaetano Pennacchi immigrated from Italy and opened a masonry shop in nearby Trenton. In 1947 his sons Anthony and John made it official as A. Pennacchi and Sons.
Signs Your Hamilton Chimney Needs Repair or Rebuild
Central New Jersey sees 30 to 40 freeze-thaw cycles most winters. Water gets into a hairline crack, freezes, expands, and widens that crack a little more each cycle. That hits Hamilton’s mix of older homes near Yardville and Groveville alongside newer construction in Mercerville, since every era of building reacts to the swing differently. Active leaks, structural movement, cracked liners, and any safety concern need immediate attention. Minor mortar erosion that has not reached the brick core can be scheduled. A repair booked early is almost always smaller than the same repair booked a year later.
- Cracked or crumbling mortar joints
- Spalling or flaking brick
- Efflorescence, the white staining that signals water intrusion
- A leaning or shifting chimney structure
- A damaged or missing chimney cap
- Water inside the fireplace
- Failed flashing where the chimney meets the roof
Chimney Repair Services in Hamilton, NJ
Every project starts with a real evaluation, not a guess. We check the flue, the crown, the cap, and the flashing on homes across Hamilton Square, White Horse, and Sandtown, so we know the actual failure point before recommending anything. A rebuild from the roofline up is the only lasting fix once brick has spalled or courses have shifted, and most Hamilton rebuilds run 3 to 5 days depending on chimney height and access. Repointing solves the problem when the brick is sound but the joints have failed, and we match mortar color and mix, including the lime-based formulas common on Hamilton’s older stock in Groveville and Colonial Terrace.
- Chimney inspection covering flue, crown, cap, and flashing
- Full chimney rebuilding from the roofline up
- Repointing with color-matched lime mortar
- Crown repair and reconstruction
- Cap replacement and reseating
- Flashing repair at the roofline joint
- Stainless steel liner replacement where code requires it
- Chimney leak diagnosis and repair
Chimney Repair for Hamilton Homes and Local Businesses
We handle private homes throughout Hamilton Square, Yardville, Mercerville, White Horse, Groveville, Sandtown, Colonial Terrace, and Wilbur, with rebuild work, repointing, leak repair, and waterproofing scoped to how each home was originally built. Hamilton Township and the surrounding area also still have factories, historic industrial buildings, and schools relying on older masonry chimneys. That institutional work gets its own dedicated process and crew.
How We Handle Your Hamilton Chimney Project
Call or submit the form to start. A craftsman visits the property, inspects the chimney, and documents the real scope.

Since we are based in town, scheduling a Hamilton site visit rarely takes long.
Local Reference Project
Many of our largest landmark restorations sit just outside Hamilton in neighboring Trenton, and the same crews handle both. Trenton Catholic Academy took limestone pointing and parapet stabilization. St. Pio Church took arch stonework and chemical facade cleaning. Closer to home, a Hamilton Square residence took a full chimney rebuild and a Mercerville home took repointing and crown repair.
