great shop!

very good shop for the size of it local handy staff have been there for years and are incredibly friendly! Prices a bit steep for paint but everything else in the shop is a bargain compared to huge places like homebase

Great Spot

I've been visiting this shop for as long as I can remember. Great amount of items for the size of shop, staff know their stuff, most have been there for decades and the prices are generally far better than the big outfits.
Used the locksmiths service once or twice too, the locksmith was a joiner by trade at one time so the two are a great combination for what he does and very trustworthy.
