I would like to thank K-Designers for the great job on the windows they installed in my home. The change in appearance was very noticeable its the first thing commented on by our guests. We no longer have to deal with the drafts within our home – everything stays comfortable without having “cold spots”. The installer was terrific while doing a very professional job. Was not annoyed but helpful with our questions and enjoyed the company of our children as they were inquisitive also.
