Rotting wood and Seal Failure are quite common these days. Window Repair Guy.com specializes in replacement casement sashes for ROW Windows and Rockwell Windows. We custom build each sash by hand one at a time using only the best insulated glass, high quality Solid Poplar Wood, Roll Formed Aluminium Clad and the best RTV sealants on the market to ensure long lasting performance of your insulated glass. Our clad colors will match your ROW or Rockwell windows to factory OEM specs. We’ll upgrade your glass to include the best LoE coating money can buy. Window Repair Guy.com uses LoE366 standard in all of our sashes at no extra charge to you. Cardinal IG has been building the most reliable insulated glass for decades. It’s what they do, it’s all they do and they do it damn well. They have the lowest seal failure rate in the country for insulated glass. Cardinal’s insulated glass units last well beyond the 20-Year warranty almost double that. When seal failure develops, air and moisture enter between the panes of glass and etches the interior surface, eventually for good. Whether you have cracked glass or not, the best way to repair the window is to replace the window glass. It takes a controlled environment, proper adhesives and time to produce a quality insulated glass unit. Don’t be fooled by same day glass products or chemical cleaners, they just don’t stand the test of time. After removing the old foggy or broken window glass, we install a new factory sealed glass unit into your window sash and the job is complete. You get a brand new insulated glass unit which will provide better performance, reliability and clear visibility for decades..
