Infinity® Energy Efficient Fiberglass WindowsNu-Vu Builders would like to introduce the Infinity from Marvin line of windows. Our newest addition in a long line of quality, energy saving products. Infinity windows are made from Ultrex fiberglass, inside and out. The strength of Ultrex fiberglass allows the window frame to be narrower than those made from vinyl or wood, giving you more glass area.


awards5And what’s even smarter is the optional Everwood interior wood grain finish. It looks, feels, stains or paints like wood, without the worries of decay over time. With optional grilles between the glass or simulated divided lines. You simply must see this window!

Dear Tony,

I am writing this letter to let you know how pleased Anita and I are with the seventeen new windows. We both feel the windows have increased the value of the house both in looks and in function.

Your installer, Jim did a wonderful, professional job. We were surprised at the minimal disruption and mess in our house considering the work you did.

The two additional windows in our walkout basement have really opened up that space allowing much more light into the room. The new windows look as if they were part of the original house.
Again, thanks much for the great job. We would recommend your company to anyone.


Just wanted you to know what a difference we feel in our home this winter with the new siding and windows. We haven’t had to run our thermostat above 70-72 degrees to be very comfortable, and as we all know we’ve had some very cold temperatures this winter. In years past we always had to have the thermostat at 78 degrees. Thanks guys for the great job well done. I love it!

With sunshine & smiles,
Lorrie & David

Dear Nu-Vu Builders, Inc.

I would like to thank all the workers and staff of Nu-Vu Builders, Inc. for the wonderful job they did on the siding of our home. You do fantastic work and the workers were very pleasant and down to earth. Their work was just the way I wanted the house to look, and even if I had a problem with the looks of it, they would have corrected the problem if needed. In my opinion the staff was excellent to deal with especially in such a competitive market. The quality of work is superb and I truly do feel I received what I paid for and more. I have had many nice compliments from neighbors and friends on how great our home looks and as a homeowner it helps the value of the home as well. Thank you again for all of your hard work and effort.
