Do listed companies quote exterior wall work for free?
No-cost estimates are advertised by 4 of the 10 companies on this page. Ask each one to quote the same specification, including whether exterior insulation is in or out, because that single choice moves the price more than the brand of cladding does and makes otherwise similar quotes look wildly apart.
