Reviews
What customers say
Earlier customers describe Stephen as knowledgeable and straightforward about costs, timing and zoning; one customer appreciated advice without a sales pitch. A customer praised the crew's site work from the foundation through utility hookups and a deck, but reported that the home did not arrive in the specified color and that the customer paid for new paint; the customer also noted an ordering oversight involving a bedroom door.
