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.

Anton did a great emergency call out job on some pipe work. I called him on Monday late afternoon, and he was able to come and see the work that needed to be done within the hour, he was then able to start work the following day, working around the roofers we had on site too. As I wasnt onsite when he did the inspection he sent me a video of the work that he was going to do, which was great! I would definitely recommend him, and will be getting a quote for some other jobs that need doing. Thanks Anton

Had a quote for roof repair which included for 1 missing tile, re fitting existing tiles, repairing flashing and gutter cleaning did not accept quote. On advice from another roofer just had the one missing tile replaced since there was no evidence of any leaks inside the loft or 2nd floor ceilings.

My names Tom, I have been in the real estate sector for over 10 years and have done everything from general property maintenance, new bathrooms, painting/decorating, demolition contracts and most recently constructed 9 ultra high spec homes. High quality and impeccable workmanship are key values to me and ensuring the client is satisfied and more, with the work they are receiving. I am very well connected with all trades and can provide a top tier service for all types of project management no matter how big or small the job may be. I am also extremely capable at doing many manual labour jobs, but often favour a shorter timeline for my clients project completion and therefore prefer to draft in experienced trades to get the job completed. Above all I am very friendly, well spoken and always keen to deliver what is asked of me.

I can't recommend Tom highly enough. He's a lovely friendly chap and supremely good at what he does. He put up 4 pairs of new curtains and the poles as well as taking down the old ones. Everything is looking fab and perfectly positioned and the curtain poles will not be coming down in a hurry! Everywhere left spotless too. I'll definitely be in touch the next time I need work doing. Thanks Tom :-)

This building firm have been fantastic from the day they gave the quote to doing the work to an excellent standard. Iva kept me updated throughout the work being completed. I didn't have to buy anything. I just went and took pictures of all the items i wanted from B&Q and they went and collected the items and paid for everything at that time. They provided all receipts and told me of any additional costs of stuff that was needed to complete the work. Iva's dad and another worker arrived on time everyday. 5
