It is remarkable how much easier and quicker work gets done in the summer months. The warmth, long days, crew productivity and soft soil make large pours quick and easy. We went from a hole in the ground to windows, roof, shingles, and a basement slab pour in a short few weeks. Over the winter, this can all be done, just with tremendous struggle and extra hoarding, heating, and difficulty. I need to avoid late summer and autumn starts, it is easily said but not generally followed through. I’d prefer to start some houses in may or June and have all the outside stuff wrapped up in October.
