Commercial Window Replacement

Commercial Window Replacement and Retrofit

Old commercial windows leak air and water, fog up and drive energy bills higher. CBE Glass removes and replaces aging window systems in office buildings, schools, medical facilities and mixed-use properties across the DC region, with modern thermally broken framing and high-performance glass.

Planned around your occupants

Replacing windows in an occupied building takes planning. We sequence the work floor by floor or tenant by tenant, protect interiors, remove debris daily and close every opening the same day so the building stays secure and weathertight.

Better comfort and lower energy costs

Modern window systems with insulated low-E glass eliminate drafts, reduce noise and lower heating and cooling costs. For buildings where only the glass has failed, consider our insulated glass replacement service instead.
