We only use OEM standards and vendors such as Pilkington, Carlite, PGW and more. These standards use glass check fixtures to make sure that the part size, shape and contour meet customer specifications. This assures that the part will fit well without excessive gaps that must be reworked with adhesive or forced into the opening, which can lead to stress cracks, wind noise, water leaks, distortion or adhesion problems. This attention to detail assures reliable quality, safety and overall cost savings for you. All of our replacements are done by NGA certified technicians with lifetime warranty against water leaks, wind noise, distortion, etc.
