Extensions- 3 Feb 2023
Marin provided a competitive quote for our building work. This included partial demolition of an old 1980s flat-roof extension, construction of an additional area, and a number of openings being made to remodel our kitchen and dining room. As part of the work we also had underfloor heating installed, flooring, and a kitchen fitted. We were initially impressed with the detail of the quote and the clear breakdown of pricing and payments. This included a Gantt chart to show expected progress. We also liked the fact that there was a relatively small deposit to be paid upfront, which was a contrast to some of the other builders we had contacted. The weekly payment schedule set in the quote seemed fair for both us and Marin, with the cost of the work spread over the expected duration. Every week there was progress, and we therefore felt comfortable paying each installment. The total cost for the work was exactly as quoted. Marin managed the team of builders throughout the project and we have been very pleased with the quality of the work. There were lots of details that I thought would be problems, however, Marin and the team are very experienced and able to problem solve any issues. Marin also managed the building control inspections to ensure that the construction was as per the approved drawings. We are very happy with the end result and would have no hesitation using Marin again for any future work.

Extensions- 7 Apr 2023
Adam came around to give a quote seemed very professional and attentive. We paid a deposit to hold a date but was pushed back as was waiting for monies from a solicitor. They started the project in July 22 stating it would take 3 Months give or take for a wrap around extension, dormas, and a drive way however come December 22 still no where completed only wrap around extension started not evens dormas or driveway done. When asking what is going on just kept coming up with excuses and They kept asking for more money in the end got another builder to finish the project off none of their work was done properly as had other tradesman in to quote to finish it off and not one of them had a good word to say. All shoddy and they have got such a bad reputation around the local area with other tradesman. Just people beware of this company as they are rip off merchants and all they are interested in is getting your money then coming up with excuses why they want more. Their slogan is “not much we can’t do” well let me tell you something is should be “there is not a lot we can do” they have caused us nothing but heartache. I wholeheartedly regret using them. Just people beware

Extensions- 2 Sep 2016
Fantastic team of Kris and Roy Tucker, very helpful and accommodating. Nothing too much trouble - they never,ever let us down. Work completed on schedule to a high standard, they take great pains to get things exactly right going out of their way on numerous occasions to make sure you are happy, even completing work out of their pocket where delays were no fault of their own. You never exactly know what you are getting when you are hiring builders but we came up Top Trumps by hiring Tucker and Sons. We are more than pleased - delighted really with the results. Well done guys! Would recommend them 110%!

Extensions- 7 Oct 2019
We hired Tom and dan from unique build to take on our extension/kitchen remodel along with a few smaller refurbishment jobs around the house. They guys priced the job from the drawings and was cheaper then the 2 local builders we was recommended by friends and also seemed to really no there stuff so we hired them for the job. There team worked really hard and kept to all dead lines and was clean and tidy. Toms team ranging from bricklayers to heat engineers and electricans was so efficient and all worked seamlessly together to get the job done on time and to budget we can’t recommend them enough and wouldn’t go to any one else for building works. It’s a shame we can’t post picture of the work the guys have done as it really does look the part well done guys.
