I'm interested in getting just a "ROUGH ESTIMATE" for converting a 4' crawl space into a useable basement. The original part of the house is 1300 sq. ft. & I understand that the basement will not be that big (approx. 1000 sq. ft. guessing). It will have to be jacked up and dirt dug out. A poured concrete basement would be nice. All the interior work, walls, wiring, will be done ourselves. Plumbing for 1 full bath will be hired out. I would like to introduce this idea to my husband, but would like some background information before I do so. Thank you for any quotes and suggestions.
