Low prices are tempting. Many homeowners and business owners choose the cheapest bid, convinced they’re saving cash. But an “inexpensive” bid frequently comes at far greater cost in the end, with cheap materials, corners cut and extra charges.

• Request a detailed estimate of materials, labor and extra fees.

• Think about value over the long term, not just what number you get.
