Here at WonderBuilds, we aim to consistently offer our usual level of service whilst navigating these unprecedented times. However, we have had to make some changes to keep in line with current Government guidance.

The latest national lockdown encourages the continued operation of construction and manufacturing industries, as well as associated businesses. Therefore, this means we can carry on supporting you throughout your journey with us, albeit slightly differently.

Our team is working from home for the foreseeable future, but this doesn’t mean we are not here for you. Our usual communication lines remain operational, whether that be through emailing/calling us or contacting us on social media.

Our sales team are also working from home, but when they do visit worksites, in order to keep themselves and you safe, they:

  • Wear personal-protective equipment
  • Use hand sanitiser
  • Follow guidance on social distancing
  • Do not shake hands

You can rest assured that the normal operation of our warehouses and deliveries is our highest priority, so that your orders will be delivered safely and on time.

We will sustain and adapt these heightened COVID-19 measures if and when required so check back here for updates. In the meantime, stay safe and healthy.

Dina Vaisman, co-founder of WonderBuilds shares a story of how two fresh graduates started a business turning into a nationwide distribution operations.

As you know at WonderBuilds we take quality and delivery very seriously so recently we have received BBA certificate for Mida Standard SBS underlay and Bipol Standard SBS mineral. It’s with a matter of pride that we share this because it makes sure that the products are compliant with Building Regulations in England, Wales, Scotland and NI, have a service life in excess of 20 years and a fire rating classification Broof(T4). It is a great addition to the range of products which are already BBA certified like Technoelast SBS mineral and underlay and Technoelast APP 180 mineral and underlay.
