Review by David
on 1st September 2026
"Gary and his team carried out a commercial upgrade of our bathrooms and kitchen. The communication was excellent and all timelines were adhered to. The team worked very efficiently and the work was done to a very high standard and all areas were left clean and tidy at the end of each day. We were delighted with the end result and also the cost of the project. Will be using Gary and his team again to upgrade the upstairs offices."

"We honestly couldn’t be happier with the work carried out by Gary and the team at 3D Building Contracts. They designed and built our garden room to our personal specification, including the timber cladding, decking, slabs and chuckies, and the finished result is absolutely fabulous. They also brought in another company to help with our driveway, which all came together brilliantly. This wasn’t our first experience with Gary and the team. They previously fitted our new bathroom and boiler, and after being so happy with their work, we didn’t hesitate for a second to go back to them for a much bigger project. Gary genuinely cares about making sure you’re happy with every detail. He works incredibly hard, takes pride in what he does and is passionate about delivering a quality finish that exceeds expectations. We would highly recommend Gary and the team at 3D Building Contracts to anyone looking for reliable, hardworking tradesmen who genuinely care about the quality of their work."

Roz Wilson - Image 1 "I ask Gary and his team to fit a new bathroom for me because I was worried about dry rot underneath the bath that was there, and he was confident he could manage it easily if they found it. They did find rot and a small job of a new bathroom became a massive job. Walls were off and floors were up in adjoining rooms searching for the end of it. At every stage Gary kept me up to date and showed me the detail of each stage of the build. He was really professional in his approach, clearly taking pride in being really thorough with ever aspect of the project. Every hurdle was met with a really confident, positive attitude. Him and Frank worked so hard. I was shocked at how fast they were! They cleaned up after themselves every day. Gary went above and beyond and was really respectful with my home. The outcome was a stunning new family bathroom and a gorgeous study and an extra new small loo! I would completely recommend him and his team for any building work!"

"Gary is a lovely guy… kept me up to date when job was starting… him & Jo were hard grafters digging up the garden and laying pipe work and slabbing and then his joiner was a perfectionist with the wall panelling and securing shelves etc. Lovely bunch of guys and very professional… great job all round. Will be getting them back for other work I’m wanting done… delighted"
