The Process

Fill out a form or give us a call to book in for your FREE consultation where you can tell us all about your renovation needs & requirements, and we can provide our expert advice. If you fill out a contact form on this page, we’ll be in touch within 24 hours.

One of our representatives will come out to see you for your initial consultation where we discuss all of your renovation desires and requirements in detail, and they’ll then return for a secondary consultation once they have designed your home improvements in our 3D modelling software. This allows you to get an extremely realistic idea of how your renovation will look, and give you a chance to provide any feedback or design changes you’d like to implement. 

Choose from the aforementioned payments plans. Whether it be interest, 0% interest or buy now, pay later, we’ll be able to find a flexible plan to meet your budget requirements. 

Once your payment plan has begun, our office team will give you a call to introduce themselves and will set up your dedicated WhatsApp group shortly after. It will include all relevant team members and your assigned Renovation Installation Manager who will serve as your main point of contact throughout the process.

Our architect will then visit the site in order to create the architectural drawings. These drawings are then passed over to our structural engineer who will in turn make the structural calculations based on this. We then submit the architectural drawings and structural calculations to Building Control. Before both get sent off, we will require your sign off giving you a chance to look everything over once more prior to submission. We will also submit the relevant applications to Severn Trent.

Once we have the go ahead from Building Control and, if required, the Planning Department from your local council, as well as any other relevant bodies — your project works start date will be issued! 

Your works will begin and our specialist teams will start to bring your dream renovations into reality. Typically, the works will follow these stages: Foundations, Brickwork, Roof Installation and Completion. Each of our teams are courteous, tidy and consummate professionals who will always show the utmost respect to your property.

After approximately six weeks, your renovations will be completed! At this point in time, we will provide you with the following certifications: Building Control Completion Certificate, Electrical Certificate, Gas Safe Certificate (for any gas works), and a FENSA certificate (for windows and doors). At WMDG, every process is followed to the letter. Just a reminder… we provide a comprehensive 10 year guarantee on all works to give you peace of mind regarding your new renovations for the next decade. Now… you can start your brand new home life!
