FAQ’s

We offer a wide variety of window styles such as single-hung, double-hung, casement, awning, sliding, picture, and bay/bow windows. Materials include vinyl, aluminum, wood, fiberglass, and composite, each selected for durability, appearance, insulation performance, and maintenance levels.

Installation time depends on several factors: the number of windows, size, style, whether existing frames need removal or repair, accessibility, and weather. A single window replacement might take a few hours; a full-house replacement or custom large windows may take a day or more.

We take care to minimize disruption: covering floors, protecting interior surfaces, using drop cloths. Debris is removed daily and we clean up after installation. For larger jobs, we coordinate with you on timing and how to access the space to minimize disturbance.

We provide warranties on both the materials (from the manufacturer) and on our installation workmanship. Specific durations and terms vary by product and project, just ask us for the details for your chosen windows.

Price depends on the type of window (style), material, glass options (e.g. double or triple glazing, Low-E), frame condition, number of units, size and shape of windows, removal or repair work, and labor. We provide a detailed, free estimate after assessing these.
