I discovered Sheridan Building while we were remodeling our first house. I called around everywhere looking for the best prices on doors, windows, siding, etc and Sheridan Building beat the others in pricing by quite a bit. I am not for certain, but I believe they have such great pricing because most of their stock is "leftovers" and such from the manufactures and local builders. I know when I was looking for windows, they could order them in directly from the manufacture for much cheaper than other places, or they also had many windows on site to choose from that seemed to be "left overs" or cancelled orders.... they had various sizes and types and brands to choose from and these on-site windows were considerably cheaper! We also checked out the doors and siding too, also much cheaper than elsewhere. I must state that we did have to build a frame for the door that we purchased, but it was very cheap when compared to other stores. This place would be great for a knowledgeable handy man remodeling a home, and especially great for a remodeling contractor! They also have great prices on the basic stocked lumber and building supplies including plywood and sheet rock ($5 per sheet cheaper than Lowes or Lumbermans was!) plus home interior trim (mouldings), all at great prices! Just make sure to check each item carefully, as some do have defects. The sales staff there are very helpful and honest in describing each item for you when need be.
