It wasn't a big surprise to me that Next Step found rot when they pulled out the old door--I had suspected something was going on. What I did not expect was that they replaced what was rotten, put in the new door--which they gave great advice on selecting--and replaced the exterior siding and interior trim around the door with such care that you would never know the door was not original. Honestly, I didn't expect to spend this much, but it was worth every penny--and, I'll probably make it up quickly in energy savings because the entire room in warmer since the new door went in. I'm glad I listened to their recommendation on the door. I've recommended Next Step to two other people looking for reliable and trust-worthy remodeling contractors. I would not hesitate to recommend them again.
