Handyman- 14 Jul 2018
Would not recommend. Grouping poor & cracking, tiles not flush causing build up of grime. Cases not fixed properly. Chipped window sill. Flooring starting to move. Didn't want to leave feedback but 2 years on and we are having to have things replaced. Don't want to ask them back as getting them to replace our bath they broke was drama enough. A lot of money spent on this project we'd of never expected to have to touch it for years. Very disappointing

What can I say. This man understands customers and all aspects of building work. Has completed two phases of work to a really high standard. This included fitting a new kitchen and bathroom, plastering and plenty of carpentry. Steve is clear on pricing and gives customers a plan. Any additional work and costing are agreed before he proceeds. Steve offers vision and ideas and helps you understand where you might be making a poor decision. Hes punctual and reliable. Overall has helped us transform our rundown bungalow into a modern family home. Cant praise or thank him enough.

Conversions - General- 30 Jan 2019
We recommend Paul highly and will definitely employ him again. Paul is highly skilled at what he does and he is very committed to the quality of his work. He ensures everything is done to a very high standard. He quotes accurately and his costs are reasonable. The breaking down and finishing of the wall between our kitchen and dining room makes our home looks great! He has good suggestions which we did not think about and which enhances the effect. We are really delighted with the quality, the speed and the aesthetics of the work that Paul has done for us. We will be asking Paul to come in to work on many other refurbishments to our home.

Extension Builder in Blackwood
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!

Extensions- 12 Jun 2026
highly recommend Acl brickwork for any major building work. They recently completed a double extension and a full driveway replacement for us. From the initial quote to the final handover, Ashley and his team were fantastic to deal with. The brickwork on the extension matches our original house perfectly, and the finish inside is flawless. The new driveway looks incredibly sharp and has massive curb appeal. Major construction can be stressful, but they kept the site tidy, stuck to the agreed timeline, and were polite and respectful of our neighbours. A huge thank you to the whole team for a job well done!

It went well, Alex and his brother came on time, laid dust sheets down and got on with their work. They did an excellent job and Alex even hoovered the passage after they removed the dust sheets. Front and back doors look great and reasonably priced. Will definitely be having them back to fix the windows.

What experience do you have with similar extensions in Blackwood?

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 Blackwood extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Do you offer a guarantee for your work? Most Blackwood 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.
