Asgard Installations

Professional Installations are available. Prices shown are for installation of the unit upon an existing base. We recommend that all Asgard storage sheds are situated on a firm, flat, level base. Ideally this should be 50mm concrete, tarmac or  on flagstones (patio). You will notice all of the products on this website site have a “base size” this is the minimum level base size we feel is appropriate for each product. a firm, flat base will ensure doors open cleanly and will make assembly of the units much easier.

Installations are typically within 5 weeks from order. Should you wish to have an install in the selected PINK areas please call us for a quote.
