Skylight cost

Three things move a skylight quote more than the brand you pick. First, new opening versus existing opening: replacing a unit in a hole that already exists skips framing and drywall entirely. Fixr shows labor around $119-$216 for a new install versus $176-$320 for a replacement unit, but that's the roof-side labor only - the framing and interior finish on a brand-new opening is what actually adds the money.

Second, whether it opens. Ventilating skylights cost roughly twice the material of a fixed unit in Fixr's figures, and motorized or solar-operated versions add controls. Fixr puts electrical work, when it's needed, at about $435-$793.

Third, access and roof type. A single-story asphalt roof with easy ladder access is the cheap case. Steep pitch, tile or metal roofing, a second or third story, or a cathedral ceiling with a long light shaft all cost more, and no online average captures that.

Compare quotes by scope, not by total. A quote that includes the manufacturer flashing kit, disposal, drywall shaft, paint and a labor warranty should be higher than one that doesn't. If one bid is dramatically cheaper, find the missing paragraph before you assume you found a deal.
