For over 50 years, we’ve been working with homeowners, landlords, estate agents, housing associations, builders and architects in the Cambridgeshire area. We’ve helped protect, renovate and extend thousands of properties and we’re proud of the fact that most of our new business comes from referrals – the ultimate demonstration of happy customers.

Since 1967, we’ve been protecting homes against damp, preserving timber and waterproofing basements. More recently, we launched APP ProBuild to provide expert building services for projects of all sizes.

We know that undertaking home projects can be daunting. That’s why we promise to make the process as easy and hassle-free as possible.

Jon is responsible for a wide range of activities within the company, from strategy planning and business development to overseeing marketing and steering the company’s finances. Having been in the business for decades, he is proud of the great team that’s been created from small beginnings.

In his spare time, Jon enjoys eating out, socialising with friends and spending time with his lock-down puppy Gloria, who believes he exists solely to give her food and attention. His claim to fame is that Kylie Minogue once apologised to him for mistaking him for a baggage handler.

In recent years, Graham has worked closely with the PCA, as an examiner for the trade association’s Damp and Timber qualification and on several workgroups, helping to increase standards within the industry.

When he’s not working, you’ll find him hiking and climbing mountains. A seasoned traveller, Graham has ridden across Mongolia on horseback, ran with the bulls at the San Fermin festival in Spain and set-up a successful backpackers’ hostel in Bulgaria.
