Fencing in Brewster — FAQ

Before Hiring a Fencing Pro in Brewster

Use this checklist to vet contractors before signing a contract.

• Confirm they will verify property lines before installation

  A fence built on your neighbor's property may need to be removed at your expense. Use survey stakes or hire a surveyor if lines are unclear.

• Ask about post setting method — concrete vs. compacted gravel

  Concrete is standard for most fences. In areas with frost heave, some installers prefer compacted gravel for wood posts to allow drainage.

• Verify the post depth meets local frost line requirements

  In the NY/CT region, the frost line is 36-48 inches. Posts set shallower than the frost line will heave and lean within a few winters.

• 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 Village of Brewster Building Department ((845) 279-3760)

  Contact village hall for permit requirements. Village is within the Town of Southeast.

• 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?
