Thanks for the feedback. Any suggestions on a higher quality window company.
Obviously, you need to do more research on the two companies that you listed. Both are fine, reputable outfits that offer more than just Silverline. As a matter of fact, between the two companies, ALL of the brands that you listed are well represented. I'd be curious to know how you approached the subject of replacing your windows since neither company is known being a discount provider (Silverline is basically a price competitive offering).
