Focus on the essentials: how the contractor evaluates your current windows, which styles and materials they recommend and why, the energy-efficiency features included, who performs the installation, exactly what the estimate covers, warranty coverage, timeline, and how they protect your home during the work.
A professional evaluation should look for drafts, damaged or rotted frames, failed seals, condensation between panes, difficult operation, and water infiltration. Widespread issues usually point to replacement, while isolated problems may be repairable—ask the contractor to explain what they see and why.
A detailed estimate should specify the window products, installation, removal and disposal of old windows, any trim or repair work, cleanup, and any additional services. A clear, itemized estimate makes it easier to compare proposals accurately and avoid surprises later.
Timing depends on the number and size of windows, product availability, any needed repairs, and weather. Your contractor should give a realistic timeline for your specific project and explain what to expect each day of installation.
Look for experienced in-house installers, clear itemized estimates, strong manufacturer and workmanship warranties, honest recommendations tailored to your home, and a long local track record.
