CDH Contractors have been amazing throughout our home renovation. They transformed our kitchen beautifully, giving it a fresh new look that we absolutely love. They also made a huge difference in our garden with their landscaping work, creating a space that feels inviting and well designed. The highlight has to be the garden room they built for us — it’s become our peace haven, and we now spend most weekends relaxing there. Their craftsmanship, attention to detail, and professionalism truly stand out. I would highly recommend CDH Contractors to anyone looking for high-quality work. We’ll definitely continue using them as we complete the rest of the renovations in our home.

Extension Builder in Abertillery
I have been plastering for 25 years, from lathe and lime, float and set to skimming and k rend, I can do it all. Nothing is too big or complex, and I'm quite happy doing a little ceiling here and there. Shed loads of experience and plenty of passion. Have built plenty of extensions and new builds from scratch over the years with my team but happy on the trowel now. I have been plastering all of my adult life I am 40 years young. Thanks

Plastering- 2 Oct 2026
We couldn’t be happier with the work Valley Construction are carrying out on our home. They are currently undertaking a large project for us, and we have been immensely impressed with the service, professionalism and quality of workmanship from start to finish. The new rendering and fascias look absolutely fantastic and have completely transformed the appearance of our home. Max and his team are incredibly professional, friendly and hardworking, and it’s clear that they take real pride in what they do. Everything is being carried out to an exceptionally high standard, with great attention to detail and a real focus on getting everything right. Communication has also been excellent throughout, which makes such a difference when having major work carried out on your home. We are absolutely delighted with the results so far and are really looking forward to seeing the finished project. We would have no hesitation whatsoever in recommending valley construction!

Loft Conversion- 11 Jun 2026
We recently completed a loft conversion with Dean and his team at Blakeon, and I couldn't be happier with the result. The workmanship has been excellent throughout, and the new loft space has completely transformed the house while feeling fully integrated with the rest of the property. What really stood out was the communication, reliability and flexibility. As the project progressed, I refined several design decisions before they were finalised, and Dean was always patient, accommodating and willing to discuss options. The project included a number of additional complexities, all of which were handled professionally and pragmatically. I also remained living in the house throughout the build, and the team were consistently respectful, considerate and easy to work with. I would have no hesitation in recommending Dean and his team and am already discussing future projects with him.

Extensions- 31 Jan 2026
Dominic and his team took on my large extension, which consisted of a 2 storey side extension and a full width single storey rear extension. The ground works were very complex but the team handled it with ease and tackled everything that was thrown at them. They arrived early each day and if the weather and light light permitted they regularly left late, but would always ask if it was ok to ‘work on’, they even worked a few weekends and bank holidays. Anyhow I couldn’t recommend Kingdom Renovations enough, you won’t be disappointed. 5⭐️

Kitchen Fitting- 13 Mar 2022
Mike fitted our kitchen and we are over the moon. His workmanship is spot on and he is a very talented carpenter. We really couldn't be happier with not only the finished result but the professionalism and manner in which he completed the job. Nothing was too much trouble and he is very friendly, polite and excellent at communication. Alongside the kitchen Mike also hung 7 internal doors, fitted a handrail to our stairs and renewed a closet wardrobe by adding fitted shelves and a new hanging rail. Again, all of this work was completed to a very high standard and we wouldn't hesitate in hiring him for future projects. All in all, an excellent and highly professional carpenter. Thank you Mike.

What to ask a Abertillery extension builder before hiring?

Before hiring an extension builder in Abertillery or extension building company in Abertillery, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Abertillery?

An extension builder in Abertillery should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Abertillery extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Abertillery?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Abertillery extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Abertillery extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
