I think you would be fine with the lumberyard, but check the references and maybe look at some other jobs they had done. Too become an Infinity dealer Marvin generally requires specific training on their products and they generally will not allow them to be sold to anyone off the street without installation. So chances are even though you saw and are purchasing them thru a lumberyard they have a Marvin Infinity certified installation division, but as I stated it will never hurt to check references and prior work.

In most situations where you are dealing with replacement windows, you would count each operator in that unit separately. Example: A twin casement, in many cases is two mulled together casements. Based on that math, you have close to 29 units which makes that pricing you have there very aggressive and fair especially given the Everwood option.

I like the deal breaker of adding $100 per window to sand...how is that calculated. I installed an integrity in my bathroom. It is a great window and you should be able to prime and paint with minimal prep. The surface is not so smooth and would should hold the paint without sanding. One of the benefits of these windows is that they are easy to paint.

Would like to hear follow-up from those chosing either Andersen Renewal, Andersen 400 or Marvin Integrity on their projects, esp'ly interested in how your windows have handled wind and cold, plus your impressions of their overall appearance. We need to replace Vetter windows damaged in a 50mph+ hail storm in Aug.'07. We will switch brands--they've resized. We need to replace windows on 3 sides of our '97 built modern home which has several very large picture windows, casements w/ transoms, and finished oak woodwork. The only prob. windows now are 2 windows placed over the whirlpool tub on north wall & west walls. Renewals' interiors have a dif. appearance but the pitch about being built to last over 50 years sounds good. Andersen 400s are going into the model homes of our builder w/ exc. customer response in past 10 yrs. A contractor is evaluating Andersen 400s for sizing and is "close" on most; he is pricing the architectural series for windows set in the stucco front. The Andersen exteriors are darker than our existing but we are thinking the vinyl "permashield" inside wrap would elim. any future mold on the rim touching the glass. Renewals only have a thin veneer and the rep. could not tell us if that could ever mold. Marvin windows look closer to what we have, inside & outside and did fantastic in wind studies done by Cons. Rpts. last month but with the wood interior, will I be sanding and restaining due to moisture along the bottom rim where we have exper'd some mold on existing windows? We constantly run an air-exchange system and seldom have windows open. We hope to have a product that can handle the extreme weather, handle future hail since it's now occurring regularly, along with straight line winds & blizzards. Thanks for any feedback!
