Chimney pointing removes deteriorated mortar and replaces it with fresh mortar — the brick itself remains. A chimney rebuild removes and replaces the actual brick and block structure, not just the mortar. Pointing is appropriate when mortar joints are failing but bricks are intact. A rebuild is necessary when bricks are spalling, the structure is leaning, or the damage is too extensive for mortar repair alone.

Signs that a rebuild may be necessary include: visible leaning or bowing of the chimney stack, large sections of spalling brick (face of brick falling away), multiple failed mortar courses that can't be stabilized with pointing, interior structural failure visible on inspection, previous chimney fire that damaged the liner and masonry, and chimneys that have settled significantly with the house. DME Maintenance assesses on-site and recommends only what's necessary — we'll tell you if pointing will do the job.

We make every effort to source brick that matches your existing home exterior as closely as possible. Exact matches are sometimes difficult with older brick, but DME Maintenance works with Nassau County masonry suppliers to find the closest available match. If an exact match isn't possible, we discuss the options with you before work begins.

For full rebuilds, yes — a new stainless steel chimney liner is installed as part of the reconstruction. For partial above-roofline rebuilds, the existing liner is inspected and replaced if damaged or if the appliance type has changed. Every rebuild includes a new chimney crown and cap.

A partial above-roofline rebuild typically takes one to two days. A full stack rebuild is typically two to three days. Complete chimney reconstruction from foundation to cap may take three to five days depending on height and complexity. DME Maintenance schedules rebuilds with same-week start dates in most cases.
