@WoW Washington please explain how the OP is to tell you the PG of their windows when they wrote: "I wanted to understand the specs of the current windows before I start calling around for selected replacement windows in hopes of not having to replace ALL the windows due to style/quality differences. For the life of me I can't seem to find any identifying marks on the existing windows." @Eric H - even if you knew the specs of the windows when they were new, I don't think those old specs would give you any kind of useful benchmark to buy windows today. Millions of people move into houses and replace the windows when they have no idea what brand the existing older windows were or their specs. I would replace in a first stage just the windows in the room or rooms that are the most problematic in the way of the traffic noise and/or where you feel they may be weakest or most deteriorated. After that, take stock of whether you want to continue in other rooms. I understand you are concerned about contractors wanting to upsell you. But at some point - even if you knew the specs of your existing windows - you are going to have to rely on a windows contractor. If you have 3 different quotes to do just 1-2 rooms, you can get a feel for the cost, and for those contractors' reliability. It would also help you a lot to go to windows showrooms and ask questions and look at what is available. Manufacturer websites will tell you where those showrooms are, as well as provide a list of approved installers.

It would probably be easier to spray primer/paint OR you can sit there and brush the paint into those crevices-pain in the butt if you ask me but it can be done. It will just be time consuming.

How about a closer up picture. What region of the country are you in? Looks like southern yellow pine from what I can see, but it may be cypress.

I’d say it’s Rock & Roll. Color is redder than Neil Diamond, and the red fades into the white, which is characteristic of R&R, not ND.
