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!

I replaced my conservatory old polycarbonate roof with a new timbered/tiled roof with a full new windows frames and a new bifold door. Great job, efforts and cooperation starting from getting quotation until execution and fitting by Mr Sing who was very dedicated and professional with his associate during the 10 days of work at house.

Outstanding service and professionalism! Our building work is in the initial stages, as we’ve just completed the brick work, and we have been very impressed with Baj and his apprentice. They have been brilliant, their workmanship has been to a very high standard. So far we have been very impressed with our results and we would definitely recommend Baj and WMG to anyone.

First class service from the sales staff through to the workman carrying out the work. They really go above and beyond to suite the customer. I would definitely use the WMDG again and 100% recommend them. They have turned our run down old conservatory into the perfect living space.

Really pleased with the work and new conservatory roof. The service was very professional and the builders (Mesha and Gurmail) who came to our property were very hard working, on time, professional, tidy and completed a lovely roof for us. Would recommend the company and the builders. Thanks again

Back in May we started our extension journey with West Midlands Double Glazing. The aim was to 🌟 knock down our existing conservatory and 🌟 rip out the kitchen. Pav attended to our wishes and dreams and promised our dream space….. he certainly didn’t disappoint. They were not the cheapest company we’d had a quote from but the trust and faith of Pav enabled me to believe I was going to get what I desired. What we had done: ☑️ new patio doors adjoining lounge and extension ☑️ widening of kitchen /extension entrance ☑️ window in kitchen ☑️ new kitchen ☑️ media wall install The team set up a WhatsApp group with all Relevant parties present which enables communication to be easy between everyone involved. I’ve never met such hard working individuals who work from early morning to late at night to get the job done and right! They are also extremely tidy workers not leaving any mess (which was much to my delight) We had some hi cups with the kitchen delivery but Pav and team addressed them On our behalf to enable the stress to be taking out of the process. I would highly recommend this company for anyone’s extension: ✅ pay in instalments each time work is completed e.g plastering, foundations, brick build etc enabling reassurance of not having to lay out all costs with little to show ✅ ease of communication between all parties ✅ quality of the work ✅ customer service every one I have spoken to has been friendly and helpful ✅ they can do everything from flooring, electrics, painting etc so you have no stress to find reliable trades men. ❌ you’ll want more work completed in the future from this company!!! Do not go anywhere else!
