What Really Drives the Cost to Rewire an Older Home
Amherst, N.H. – September 18, 2026 -- Homeowners weighing a home rewiring project should expect costs to swing widely based on square footage, wiring age, and accessibility, according to electrical contractor Thomas Reilly of TC. Reilly Electric LLC in Amherst, NH.
Reilly's insights, featured in a HelloNation article, focus on why rewiring decisions in Southern New Hampshire and Northern Massachusetts hinge on more than just budget -- they're often a safety necessity.
Square footage drives labor hours and total cost
Smaller homes with open attic and basement access typically require less labor. Larger properties demand more time to update outlets, fixtures, and circuits, and to safely remove or abandon old wiring while meeting code.
