How to Reduce Window & Door Callbacks Before the Homeowner Moves In
A successful window installation is about more than putting a window in an opening.
Poor installation practices, missed details, inadequate communication, and a lack of accountability at any stage can lead to water infiltration, air leakage, performance issues and costly callbacks.
At Global Window Systems (GWS), we believe the best way to prevent these problems is through coordination, quality assurance, and transparent accountability from the start.
That’s why we sell, furnish, and install our European window and door systems and why we’ve developed GWS ProjectPane, our proprietary project-management shared app.
One Project. One Record. Everyone Accountable.
ProjectPane provides architects, builders, project managers, and GWS with a shared view of the project as it progresses, including:
- Installation tasks and checklists from opening preparation through completion
- Real-time status updates at critical phases
- Photos, videos, documents, CAD files, and comments attached directly to the project
- A history of changes and updates, including who made them and when
- Clear communication and accountability among everyone involved
The goal isn’t to point fingers when something goes wrong.
It’s to create a process where installation and potential problems are identified, documented, communicated, and addressed before they become callbacks.
ProjectPane is just one of the many value-added services GWS provides to help protect the integrity of your project and your reputation.
Better coordination. Better documentation. Better accountability. Fewer surprises.
