The Marc Of Clean Windows

My name is Marc Barrieau and I've been doing residential window cleaning full-time since 1991 and I still love it! I am fully insured and all the work is done professionally by myself (no employees).+ I almost always answer my phone-860 508 0447 if I'm near it - so call me! Please visit my website for more information I ALSO do powerwashing of houses/decks/patios etc. Lastly --i have an eBay business. I resell things. If you have ''stuff'' in your garage, basement etc that you don't want (most people do) - I might give you $$ for it! Please ASK ME! You'd be surprised what i might buy from you!

There was spaces and on three of the windows there were very big gaps, around the new doors there were also gaps that should have been caulked. We allowed the energ...

Description of Work
Replaced all windows in the house and back and front door. We were not crazy about are sales person. When he came in for the estimate he tried to be funny and said our kitchen need to be improved. it was very insulting. One of the main reasons we went with this company was it had free financing, also he was very pushy. Looking back we wished wee kept looking.
