Chimney Pointing in Nassau County
Chimney pointing — also called tuckpointing or repointing — is the process of removing deteriorated mortar between chimney bricks and replacing it with fresh mortar. Mortar joints have a useful lifespan of 25–30 years under normal Long Island conditions. Nassau County's coastal exposure to salt air and Atlantic moisture accelerates this deterioration. When mortar recedes or crumbles, water has a direct pathway into the chimney structure. Freeze-thaw cycles then force that water further into cracks with every winter. DME Maintenance removes the failed mortar to proper depth and replaces it with a mix matched to your existing joint profile — same-day assessment available, Nassau License #H0101570000.

How to Get Chimney Pointing Done in Nassau County
Schedule an on-site inspection
Call DME Maintenance at 516-690-7471. We inspect the chimney from ground level and the roof, identifying which mortar joints are failing and the extent of the deterioration.
Review the written estimate
We provide a written, itemized estimate on-site before any work begins. Pricing covers the specific courses and faces that need repointing — no vague quotes.
Rake out deteriorated mortar
Failing mortar is removed to a depth of approximately 3/4 inch using grinders and chisels. This ensures the new mortar bonds to solid material, not crumbling old joints.
Apply new mortar
New mortar is packed into the clean joints in layers, tooled to match the original joint profile, and color-matched to the existing masonry where possible.
Apply waterproofing (optional)
ChimSaver breathable sealant can be applied after repointing to protect the repaired masonry from future water infiltration — often done in the same visit.

★★★★★Frequently Asked Questions
How much does chimney pointing cost in Nassau County?
DME Maintenance charges from $600 for chimney pointing in Nassau County. Full chimney pointing for heavily deteriorated chimneys typically runs $600–$900 and up. All quotes are free and on-site — call 516-690-7471.
What is the difference between pointing and tuckpointing?
Tuckpointing and pointing (repointing) are the same thing — removing deteriorated mortar and replacing it with fresh mortar. After pointing, DME Maintenance recommends ChimSaver waterproofing to protect the fresh mortar immediately.
How long does chimney pointing last?
Properly done chimney pointing lasts 25–30 years under typical Nassau County conditions. Following pointing with ChimSaver waterproofing treatment extends the life of the repair by protecting fresh mortar from moisture exposure.
What causes chimney mortar to fail?
Freeze-thaw cycles are the primary cause on Long Island — water infiltrates the joints, freezes, expands, and mechanically breaks down the mortar over years. South Shore homes near the water experience accelerated deterioration from salt air. Most Nassau County chimneys show significant mortar joint failure after 20-30 years without maintenance.
Can I wait on chimney repointing?
Minor joint deterioration can wait a season if no water is actively entering. Once joints fail completely and brick faces begin to spall or water is entering the chimney structure, repairs become more extensive and expensive. Early repointing is always cheaper than the alternatives.
