• Choose your siding style carefully. Board and batten siding costs 1.5 times more than what you’d pay for shingle or clapboard siding. Unless you have a specific aesthetic in mind, opting for a more affordable style can save thousands.

• Get multiple quotes. Get quotes from at least three siding contractors and compare based on experience, cost, and installation timeline.
