Masonry in West Nyack — FAQ

Before Hiring a Masonry Pro in West Nyack

Use this checklist to vet contractors before signing a contract.

• Ask about their mortar mix and whether they match existing mortar for repairs

  Using the wrong mortar hardness (Portland cement on old lime mortar) can crack historic brick. Color matching matters for appearance.

• Verify experience with structural masonry vs. decorative veneer

  Foundation repair and structural work require a different skill set than building a veneer fireplace surround. Ask about relevant experience.

• Ask about drainage provisions for retaining walls

  Every retaining wall over 2 feet needs drainage (gravel backfill, weep holes, or perforated pipe). Skipping drainage causes wall failure.

• Verify Home Improvement Contractor license with your municipality

  New York counties require Home Improvement Contractor registration. Check with your local clerk's office or building department.

• Confirm general liability insurance and workers' compensation coverage

  Ask for a certificate of insurance (COI) naming you as additionally insured. Workers' comp protects you if a worker is injured on your property.

• Get 2-3 written estimates that itemize labor, materials, and timeline

  Lump-sum quotes hide details. Itemized estimates let you compare apples to apples and catch hidden costs.

• Check permit requirements with Town of Clarkstown Building Department ((845) 639-2100)

  West Nyack is a hamlet within the Town of Clarkstown. Contact Clarkstown Building Department for permits.

• Ask for 3 recent local references and actually call them

  Ask references specifically: Did the job finish on time and on budget? Were there surprises? Would you hire them again?
