Thank you! I will explore further for help. I appreciate you reaching out.

I am going to make a guess and say you are working with an oil-modified finish (poly) If you are ok with a close match, you may want to try using a light color stain, like Minwax /Dura Seal- Colonial maple, golden pecan or oak, but remember it will be darker once this part oxidizes (8-9 months depends on sunlight).

Are you DYI?

No, I am looking to have a pro install new hardwood that is a match to my existing; however, I had one come to my home and say I had Bruce pre-finished hardwood floors in a natural red oak. It didn't match, but I believe it was because my older floors have worn over the years. When I pulled back an area that was covered by an area rug, it looked like it was the same wood. I have so much existing wood that I was concerned installing new unfinished hardwood, then having the entire first floor sanded and stained to match would be both costly and messy. I thought perhaps a border to trick the eye between the old and new might be a solution, but I'm not sure if I'll like it or how it would turn out.

There is one way to do this without having the pain of sanding/refinishing everything "right now":

1) Install SAME SPECIES/same "cut"/same board width

2) Stain a NEW COLOUR (decorative trim or not...your choice) and wait for 10 years.

3) Sand and refinish EVERYTHING all at once in 10 years.

This will help save you, for the next 10 years, from having a full sand and refinish done...but it is COMING. Your original floors are 14 years old. They are more than 1/2 way through their life cycle. In another 10 years (or sooner) you will NEED to sand/refinish them. There is no way around it. It will have to be done.

For some floors, 10 years is too long. They can only make it another 5-7 years. Some finishes have to be completely resanded/refinished at age 17 years. Your existing floors are just around the corner from that birthday. Some finishes are in REALLY good shape and can push it to 25-30 years (30 years is rare but it happens).

The IDEAL situation, is of course, to have everything done right now and be done with it. Just get everything on the same page today and be done with it for another 25 years. If that can't be done, you should plan to have everything sanded and refinished (new and old floor) in 10 years from now. Get all the floors to the same "age" (finish) at the same time. Once they are all on the same schedule, you can relax and enjoy your home.

At an average of $5/sf for a full sand and refinish, I can understand why you don't want to do the "other" 1500sf right now. The question becomes, how happy are the current floors? Are they going to make it another 10 years? Or will they be "done" in 5-7 years? If they are close to being "refinished", would you contemplate holding off the installation of new hardwood for a few more years and then go ahead and do everything at that time?

When you speak with the contractor/s see what tricks they may use to duplicate old floor, old timers that been around have their own methods. have them make you samples.
