Wood Floor Gap - Use Putty?

We just had an addition put on, and the builder left gaps between the new and old floors of about 1 1/4" (varies along the seam). Is there any putty that can be used to fill the gap, and support the carpet properly?
How would you recommend we fix it?
Thanks in advance for any help!

think "expansion". you still need a small gap when you get done filling in the majority of the gap. usually about 1/4" is sufficient for most floors, depending of course on the size and the variation in humidity, blah, blah, blah for your area.

JoeV thus spake:

Is there a reason you can't use a wooden filler strip or standard threshhold trim? Just a thought...
