Prostaff serves those in the Private Sector

​Prostaff has extensive experience in servicing commercial grade windows. During our 30 years of service we’ve diagnosed a wide range of inoperable and energy wasting commercial windows.  Ingenuity, determination and vast experience have produced remarkable results for our clients. Prostaff is confident we can find a solution to your commercial window problems.  Samplings of window problems we encounter are:

Air Infiltration-Failed/deteriorated wool pile allows enormous building energy loss

Inoperable Sashes-Misaligned and rattling sashes won’t open or close

Fogged/Failed Insulated Glass-Due to micro cracks in glass or premature seal failure

Leaks-Moisture infiltration due to failed caulk sealant or failed weather flashing

Sash Too Heavy to Open-Due to failed Lift Balancer System

Sash Crash- Due to failed Lift Balancer System

Insect/Pest Infiltration-Due to damaged screens or no screens in opening

Can’t Lock/Secure Windows-Due to Sash Interlock System failure

Yes we are proud of our record but even more gratifying is the smile on our client’s face after we’ve fixed their window problems.
