Our hard work and levels of customer service were recognised at the 2017 Portsmouth News Business Excellence Awards where we were runners-up in the Small Business Of The Year award and winners of the Customer Service award. To pick up two prestigious awards evening was a demonstration of how we commit to our customers.

As a no frills business we choose to keep things simple and affordable which enables us to pass on much of our negotiated trade discounts to our customers. Our prices are among the best to be found on the internet.

We’re proud supply partners to the Landlords National Property Group, Portsmouth & District Private Landlords Association and projects featured on national TV such as Restoration Man and Amazing Spaces.

What Makes Us Different?

Our added value is that we offer technical information and support to general builders, tradesmen, architects, self builders, landlords and DIY homeowners. This often involves going to a site to look at a project and advise on a suitable course of remedial action. Site meetings are carried out locally in all areas of Hampshire including Fareham, Portsmouth, Southampton, Winchester and into neighbouring counties, West Sussex, Surrey and Dorset along with London and Kent.

So far we have had the opportunity to supply to major developers, specialist contractors, international clients, landlords, homeowners and proudly, to the Portsmouth Historic Naval Dockyard. In addition to a range of products, we provide basement waterproofing design and specification services for builders, developers and homeowners. Please call 01329 235252 for more details.
