As a proud family owned business, we have been trading for over10 years and have improved  so far over 600 properties across Watford, NW London and the Home Counties. Green Contractors are fully insured, offering an insurance backed guarantee, deposit protection and are approved  Stroma/Napit  PAS 20-30 EWI Installers. We are also operating strictly under the Trustmark guidance in offering EWI services together with the Green Home Grants Scheme.

Green Contractors Ltd are an External Wall Insulation & Rendering Specialist. 

Currently we are covering Watford, Hertfordshire, NW London, the Home counties, Peterborough, Cambs, East Northamptonshire, Bedfordshire and South Lincolnshire. At present, the main Warehouse is still at Unit 4 Bermer Place, Imperial Way, Watford WD24 4AY (next to Howdens). The newly opened Peterborough branch is much larger and is located at Unit 7, R/O 58 The Causeway, Thorney, PE6 0QH (opposite Land Logical Concrete). Over the next 6-9 months we plan to fully open our 20,000ft base, just off the A1M outside Peterborough, to facilitate and support the fast growth of the business.

Residential customers:  All new enquiries please call the main office on 01923518395 We will  ask some basic questions about your property and send you an email containing the information necessary for the grant application. The quotation will normally be emailed to you within two working days.

Our opening hours are 7am to 6pm. Should you want to collect samples or visit our rendering showroom, please call first to book a time. During your visit, please be careful to observe social distancing rules and must use the hand sanitizer stations located at both doors as well as wearing a mask. Please be patient with us as we can only allow 1 person or a couple in our offices at any one time.  During the "Covid-19 lockdown" we have continued working close to Watford, whilst observing all social distancing regulations.

Site surveys are only available for those living within 15 miles of our two locations, who are deemed vulnerable or unable to use a smart phone. When a member of our staff does survey your property, all government guidelines related to social distancing must be respected. He/She will have a short time allocated on site to take photos and measurements and asses the enabling works and scaffolding needed to do the works.

To book an EWI installation slot a bank transfer is preferred and our bank details are on your Quotation.  Alternatively, you can call us for a card payment over the phone. This is fully refundable in case of any Covid 19 issues, including redundancy or in event of your grant application being declined. Our office staff and surveyors will help you with any customer service before, during or after your installation takes place as well as any technical information you might need.

All ongoing commercial rendering projects, please call your designated site foreman on his mobile. Any drawings should rather be sent to this email address and the surveyors will work on them as soon as they can.

We are re-branding and launching our new digital website very soon,  Please re-visit us shortly to find great industry content, case studies and much more.   To accommodate the unprecedented demand created by the coming  Green Homes Grants we are stepping up our operations.
