Chimney Tuckpointing in Lynbrook: Protecting Your Masonry Before It Fails

Tuckpointing is the most underperformed chimney maintenance service in Lynbrook. Homeowners see their chimney every day and assume it looks fine. But mortar — the material between the bricks — deteriorates faster than the brick itself. By the time it is visibly failing, water has already been getting in for months.

What Tuckpointing Is and Why It Matters in Lynbrook

Tuckpointing involves removing deteriorated mortar from between the bricks to a depth of about 3/4 inch and packing in fresh mortar that matches the original. It is not cosmetic — it is structural. Mortar is the waterproof seal that prevents rain from penetrating the chimney wall. In Lynbrook, where we see 45-50 inches of precipitation annually and harsh freeze-thaw cycles, mortar that was installed 20 years ago is reaching the end of its life.

How to Tell if Your Lynbrook Chimney Needs Pointing

From the ground, look for gaps between bricks, crumbling mortar that falls when you press it, white staining (efflorescence) on the brick face — a sign that water is moving through the masonry — or bricks that have begun to shift or loosen. From inside, staining on the fireplace back wall or a damp smell are signs that water is already entering. A Lynbrook chimney that has not been pointed in 15-20 years should be inspected.

What Pointing Work Involves — and What It Costs in Lynbrook

We use an angle grinder or cold chisel to remove the old mortar cleanly, then pack fresh Type S mortar (the correct specification for chimneys) and tool it to match. The work is done from a ladder or scaffold depending on chimney height. Most Lynbrook jobs take 3-6 hours and can be completed in one visit. Pricing ranges from $500 to $1,500 depending on the extent of deterioration. Call (516) 690-7471 for a free estimate.
