Painting & Decorating- 29 Apr 2026
After being let down by a previous tradesman, finding Eddie was a game-changer. He recently completed decorating, painting, and detailed woodwork at our property, and the results are fantastic. From the start, Eddie was professional and straightforward. He provided a fair quote and stayed true to it. Why we highly recommend him: Punctuality: He arrives exactly when he says he will. Incredible Work Ethic: He is extremely hardworking and dedicated. He even worked late and through weekends to get the job finished. Cleanliness: He is incredibly respectful of the home, leaving everything tidy at the end of every night. Knowledgeable: He clearly knows his trade inside and out. He even took the time to teach me a few things along the way! We are so impressed with his work that we are already planning to hire him for our upcoming bathroom and kitchen renovations. If you are looking for a builder who is reliable, skilled, and honest, Eddie should be the first person you call.

Extensions- 11 May 2026
These guys are the real deal. So very impressed with the work that that have done. You can tell a lot about a building company with what condition they leave the building site and they left it spotless and very clean. Which lends itself to the high level of craftmanship they have put into converting my brick shed into a gym. Nothing is a problem for them and they turn up on time when they say they are and crack on with it. Mark offers recommendations for the work and due to this what I initially requested is even better than I expected. It has been a real pleasure having them on site and would offer them future work for sure.

Extensions- 30 Jan 2020
We cannot thank Danny and Constructek enough for our beautiful extension. From his first visit to look at the project and quote through to the last this week to complete Danny and his team have been amazing. All of the trades people were so friendly and accommodating. Danny handled all of the tradespeople and deliveries for us, making the whole process such a job. The standard of his work is beyond exceptional and it is clear why he is a Master Builder. Nothing is too much trouble and Danny accommodated our every request. He and his team made our project a joy to have built. We really cannot recommend his company enough. We would be more than happy for any of his potential customers to come to our home and see the exceptional work they have done. We are over the moon with our finished project and will be using Danny and Constructek again. Thank you so very much more making our dream a reality.

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