We have a website on file for 14 of the companies on this page; 11 publish a contact page and 6 list a public email. We count these figures across the companies on this page; distances are straight-line, and hours and prices change, so confirm the details with the company before you book.

Do any of these companies quote without charging?

The free estimate promises less on a multi-trade job, and it is advertised by 2 of the 15 companies here. Free normally buys a walk-through and a ballpark figure. A real price takes measuring, trade pricing and desk time, so design-build firms often charge for that stage and credit it against the work if you sign.
