About Dianaliang

An Energy-First Window Crew for Grand Rapids Homes

Dianaliang installs replacement windows for homeowners across Grand Rapids, Michigan and the surrounding Kent County communities. We focus on the numbers that lower a heating bill: a low U-factor, the right Solar Heat Gain Coefficient, and glass packages built from low-E coatings, argon fill, and warm-edge spacers. Vinyl, fiberglass, and wood frames all get the same attention to the seal.

West Michigan is hard on windows. A single sash faces January wind off Lake Michigan and August humidity within the same year, so a good seal matters as much as the glass itself. That is why we template every opening for the real conditions, from the settled frames of a Heritage Hill foursquare to a newer build out toward Comstock Park.

What Sets Us Apart

• Efficiency you can read. Every unit ships with an NFRC label, and we show you the U-factor and SHGC before you commit.
• Honest, written quotes. We compare frames and glass with you, then put the price in writing before any work begins.
• Clean, careful installs. We protect your floors and trim, seal with flashing tape and foam, and finish the job tight.
• Local and licensed. We are a licensed, insured Grand Rapids-area crew, and a real person answers when you call.
