Trimming the interior of a residential window


One of the the things we do well at Gravina’s Window Center of Littleton is interior trim work. We have trained our installers to be expert craftsman in their field. Is interior moulding work a window replacement secret? Not really. So why not give an example of what to expect with interior trim.

We don’t always need to trim the interior of our windows but when we do we want the wood work to enhance the customers home. After all, a little trim makes a huge impact on new replacement windows. It makes the room look so much better.
