Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!

Dmitry

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

Overall I am very happy with the entire experience of dealing with Dolphin Windows. From the start the communication was at an excellent level and I never had to chase for anything. The cost of the windows was very reasonable with no unexpected costs involved. They were also very helpful in suggesting cheaper options for window style choice. The windows were installed on time and they cleaned up very well after the work was complete. All timelines were met through the process. A super job!

Leroy and his team did an amazing job painting a large bedroom and laying flooring in our hallway in just 4–5 days. The hallway floor was very uneven, and a previous carpenter had struggled with it. Leroy and his brother had to undo that work, level the floor, and install the new flooring from scratch. They handled it all with great skill and professionalism. The finish is flawless—we're really happy and would highly recommend them.

No reservations in recommending William Winter. He and his two lads attended promptly and worked diligently to repair the chimney and roofing to a high standard. The boys were polite and appreciative of cold drinks offered. William took photos of the damage and his quote was more than reasonable. Helpfully, he pointed out areas that could prove troublesome which were dealt with promptly.

Alin is reliable, punctual, and honest. We agreed the price of the job and I did not have any surprise, and when we had to do something extra he was very reasonable with price. He and his team started on time, were very respectful, did a good job, and are very easy to work with. I would happily work with them again.

Kieran did an excellent job of digging out an overgrown flower bed and rebuilding a brick retaining wall topped with coping. He was most helpful in discussing options, worked very hard, and was a pleasure to work with. We are very satisfied with the end result - a great improvement.

There is only one word to describe Sydney and that is ‘ amazing’. From the start he took time to discuss what we wanted from the design to creating an en suite and refurbished our existing bathroom. He is very hard working and some days put in a lot of hours , he is professional, honest and reliable and did a great job paying particular attention to detail. If you’re lucky he sings while he works! I definitely recommend Sydney .
