How DaBella Windows Works
DaBella runs the window replacement process in three stages. The full cycle, from consultation to completion, typically takes 5 to 10 weeks depending on customization and seasonal demand.
Initial In-Home Consultation
It begins with a 60 to 90 minute in-home consultation. A DaBella design consultant measures your window openings, discusses style options, demonstrates product features, and provides a detailed, itemized quote.
Custom Window Manufacturing
After you sign, DaBella sends your measurements and specifications to its manufacturing partner. These made-to-order units generally take 4 to 8 weeks to build, ensuring each window fits the exact dimensions of your home.
Professional Installation
A factory-trained team handles installation. Most whole-home projects of 10 to 15 windows finish in 1 to 2 days, with the crew removing old windows, installing and sealing the new ones, and cleaning up before leaving.
