We ordered our products in April were expecting installation no later than the end of August. We paid 50% at time of the order. August came and went still no delivery of promised date. Finally in October one man crew came to install extension to car Port Roof. The Bay window did not arrive until December. We were somewhat frustrated with the delays and excuses. In the end the installers were professional courteous and obliging. Installation looks good workmanship was excellent product first class. Both the window and the extension look great.
