I was looking for someone reliable to do my kitchen to the required specifications and I must say I am very pleased with Dhillon construction who managed the whole project and my Kitchen looks the best part of my house. Full kitchen installation was done with flooring, tiling, skimming the wall, ceiling, electrical and plumbing and he also opened a new french door on my kitchen wall and closed the old door with great brickwork. Thankyou Baltej Dhillon and team.

Extensions- 30 Jul 2019
Nathan from HCJ Building Service was excellent in all respects. He built an extension to our garage, which involved block-work, timber framing, roofing, cladding and installation of a door. When he visited the site to provide an estimate, he was enthusiastic and knowledgeable. His quote was competitive and he promptly answered a few questions we had about some of the technical details. When working on the project, he always arrived when he said he would and left the site tidy when he finished. My wife and I were impressed with how hard he worked, barely stopping to drink a coffee. When we interrupted him to find out how things were going he was happy to give us an update. He was always friendly and polite. He completed the project on time and left the site as he found it, removing all his waste. The work was done to a very high standard. We are really pleased with the result. This extension has freed up space in the garage for my woodworking hobby. We will definitely be coming back to Nathan to quote for future building projects. Now that I have my woodworking man cave my wife has started thinking about the kitchen...

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.

I have been using HS Construction London for many years ranging from a full house refurbishment to smaller unexpected issues. I have always found them to be reliable and genuine. There are never any hidden surprises in the end. Sunny listens to his customers and also gives decent advice where needed. Their work is of quality and has a long life. I particularly impressed with how they complete the job in a timely manner. All the materials that have been used are of great quality; and it shows. In addition, HSC has many contacts such as architects, suppliers etc which has made my life so much easier. Reasonably priced and with great knowledge, i would certainly use them again.

Extensions- 2 May 2019
I would like to say that Danny and his team did a fantastic job on the single storey extension to our home, they were very efficient and tidy during the whole build and kept us informed at each stage. I was very impressed with the speed in which it was completed, and the building inspector also commented on how much of a good job it was. Danny is very approachable and informative and added some really nice touches to the extension after consulting us which gave it that bit extra! some of his ideas I wouldn’t have thought of, I would not hesitate to recommend Danny, we are very happy and looking forward to appreciating their hard work.
