DATA CONTRACTS SPECIALIST MAINTENANCE LTD and LINGARD LTD have been successfully trading for over 20-years and both have jointly become the market leaders in Concrete Repair, Waterproofing, Chemical Lining and Specialist Maintenance.

The success of the two companies has been down to the full commitment of all staff and the on-going support from all existing clients, who over the years have selected to employ the services offered by each of the companies, which in turn has created growth and sustainability.

As part of the on-going commitment to improving customer service and ensuring all customers are able to benefit from the breadth of services across the two companies, we have taken the decision to consolidate both DATA CONTRACTS SPECIALIST MAINTENANCE LTD and LINGARD LTD into one business unit that will be named ONSITE SPECIALIST MAINTENANCE LTD. The contact details will remain unchanged apart from the website that can now be accessed by visiting www.onsite-sm.co.uk

We trust the above is informative and we look forward to further strengthening our on-going relationships.
