A new look to my house. My fantastic new windows have transformed my home.
Stephen with Sash Windows did very good work – was responsive to the first call and in giving the estimate, and scheduling. Prompt, efficient, fast workers but without losing good workmanship – so important! Careful with the wood surrounds. Cleaned up well after the work was completed. I could well recommend this firm. I had insulating strips installed.
