    It's time to tackle your to-do list


    My local builders merchant so I use them quite a bit from mixing paint, to tools, skirting board and aggregate. Helpful and friendly , this is the first place I go to and they always carry my stuff to the car - I never need to ask. Excellent unbiased advice and they don't rush you out at closing time!


    Great company to deal with. Friendly knowledgeable staff always eager to help (& to have a laugh with). Good prices and good selection of materials. 👍

    Used them for years, always been very reliable. Not sure how they fair on price but they're certainly competitive. Highly recommended.

    Great, friendly service from Bob and Dave, who have expertise in garden machinery and fixing issues with them. I will continue to purchase machinery from here and will always visit Bob and Dave if my mower starts playing up!
