Chris Kennedy – Course Manager Wentwoth Golf Club `We have been using Complete Weed Control for over 10 years now, they give us a great service and are always quick to react to anything we require’ Rob Collins – Wellington College `They have been doing the spraying for us for numerous years and I can not fault them, they use skilled operators who know their job well’. Sometimes when we are busy and the weather is against us Richard will make sure they are flexible to our requirements, which is key for us’. ‘We also use them to install the new Baseguard product which always looks great when completed’.
