Conversions - General- 7 Apr 2019
Dean has been truly remarkable throughout the whole process. Following the initial visit he had an excellent grasp of the project and was able to recommend the most practical approach to the works while having factored into consideration our original scope for the new garage conversion. It was very apparent from the outset Dean’s building experience and knowledge compared to other contractors (notably an excellent eye for detail). Most importantly Dean was very earnest yet competitive with his approach, his pricing was transparent and he provided a clear breakdown of the scope and project timeline which was greatly appreciated. Once agreed the job itself was undertaken in an expedient yet structured manner. Dean works very swiftly and was extremely dedicated (almost machine-like)! He was true to his word and the project was completed within the agreed timeframe, in fairness with a number of days to spare. He placed careful choice with his sub-contractors and likewise they performed in a similar manner. The end product is that we were handed a high quality downstairs bathroom / utility room with general piece of mind given the professional manner and approach to the work. Sincere thanks to Dean for his efforts, I would highly recommend him for any project, big or small!

Bricklaying- 22 Aug 2022
Adam did an excellent building job, both brick work and carpentry, at the end he cleaned up and removed all the debris. What happened Adam started on Tuesday 16th August and expected to complete the work in 1 day, but he had to return the following day. Wednesday he worked till mid-day, leaving to work on another job. Thursday he didn't turn up, same on Friday. Eventually I managed to make contact with him and he said I will be there on Saturday. So on the Saturday we expected him at 8 to 8.30am. I rang him at around 9.00am to say where are you, he explained he had been working on another urgent job, but he would be with us around 9.30am. He arrived and by 11.30am the job was finished. We have a small well in our back garden, the roof had collapsed, it needed a large piece of plywood with tiles on the top. Adam said I will bring you a piece of plywood at no charge, either tonight or during Sunday, we felt very happy about the whole proceeding. Of course over the weekend no Adam arrived no plywood nothing, no email, or answer to my phone call. So finally on Tuesday we went out and purchased a large piece of plywood. So there you have it a very good workman, but keeping his promises needs to be considerably improved.

I wanted a side infill extension, converting a one bed into a 2 bed. The works was undertaken by Coulsdon Builders which took around 8 months. I made several changes throughout the project hence the delay. They were so accommodating and never had an issue and was always happy to cooperate. The cost of build was £120k and we stuck to the budget. I am delighted with the works and am grateful they made my house a home. They were clean and tidy on a building site and always kept me updated on progress. This is one builder that I highly recommend and trust. Great work guys and thank you again!

Extensions- 31 Jul 2016
Nick built a two storey extension which added two bedrooms, bathroom, utility room, downstairs toilet and much extended kitchen. All work was completed to a high standard and all workers were very polite; no problems whatsoever. The extension was delivered mostly to budget with extras clearly explained. I would highly recommend Nick for a trouble free build.

What qualifications and experience do you have as an extension builder in Redhill?

An extension builder in Redhill should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

What experience do you have with similar extensions in Redhill?

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