Our Fixed Price Guarantee

We operate with a fixed price guarantee where you will never pay more than what’s been agreed in your contract. The only instance where the price of your works could increase is at the foundation stage where, if your grounds are deemed to require additional reinforcements by external bodies, extra materials and labour will be required. Apart from that, there is no other scenario where your price will be raised.

We Can Work With Your
Architects

Already have your drawings done by another architect? Not a problem, we are happy to work with them and build from their designs, as long as they comply with all local regulations.

Need Your New Kitchen
Fitting?

If a new kitchen is part of your renovation plans, not only can we build your kitchen extension… but we can also design and fit your brand new kitchen as well. We really mean it when we say we do everything under one roof!

The Communication

As soon as you sign up for a project with us, you will be added to a dedicated WhatsApp group with your project management team and renovation installation manager. At every stage of your project, we will keep you completely informed to ensure complete transparency.

In addition, we are always just a phone call away, and you can always chat to our team on site!

About Us

West Midlands Building Company is the sister company of West Midlands Double Glazing. While the latter specialises in windows, doors, porches, conservatories, conservatory roof replacements and orangeries, we are experts in house extensions, garage conversions, kitchens, home renovations, house remodelling and commercial construction.

The great thing about working with WMBC is that we can take any residential or commercial project from design to completion. Our holistic range of services ensures that no matter what your project vision may be, we have the ability, experience and track record to bring that vision into reality.

Any project should be a stress-free, fulfilling and rewarding endeavour and by choosing us as your partner in this endeavour, you will be in the most trusted hands in the region and we promise that you will not receive a more professional, communicative and seamless service.

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!

Excellent team effort

Just wanted to say how pleased we are with our replacement conservatory recently executed by WMDG. From start to finish it was a first class experience. The whole team played their part which resulted into a fantastic new living space. A special thanks goes out to the installation team who worked exceptionally hard and reduced the time of removal of the existing conservatory and the installation of the new conservatory to three days which was really important to us as the installation was during the winter months and we did not want our existing floor and decorations destroyed during this process. They were very polite and cleaned all the rubbish and work area thoroughly before leaving. A big thank you. Would highly recommend this company.
