Groundwork & Foundations- 1 Oct 2024
It was a complex job requiring the removal of an earth bank, ground works to include reinforcements to an independent engineer's specification, and re-erection of a boundary wall in a locally listed area against a busy road. We had some problems during the works but all were resolved to mutual satisfaction and with good humor. The end result is a high quality, solid wall of which Dave and his team should be proud

Extensions- 30 Dec 2024
I am extremely happy with Jim and team's work. Their work is of high quality and they give attention to details too. I received a lot of positive feedback from friends/family on the extension work they have done. I can confidently say that he's delivered a quality work for a very reasonable price. Jim consulted us throughout the building process making sure we're happy with the decisions. If he found out anything outside the project work, he'd inform and fix it. I agreed to carry out some additional work including front side rendering, bathroom refurbishment and changing some internal doors. He completed all additional work timely and for a reasonable price. I highly recommend Jim for any building work. I'll be going with Jim for any building project in the future.

Extensions- 3 Oct 2025
Job was to convert WC in outbuilding into a full bathroom, do walls and ceiling in outbuilding to convert into an office space. Price was agreed with things planned, still with some issues towards later part of job, It worked out in the end. Overall I am giving 3-4 stars as quality of work is good. Just need to have things written down with him, and a thorough discussion on plan before commencing work and agree on payment plan. suggested to keep 20% to be paid at completion.

Absolutely disaster. He did not complete the job after receiving his full payment and could not get hold of him again. I had to deal with the council and application. Scam!

Extensions- 11 May 2016
Really happy with the work Paul and his team did on our extension. They were quick, neat and tidy throughout and kept us updated at each stage. There were some early design changes which building control insisted on and they were happy to adapt to the new plans without fuss. We couldn't believe how quickly it was all finished and the standard of work was very high too. Would definitely hire again if we ever need to.

Groundwork & Foundations- 9 May 2026
I found Zan through MyBuilder and was very impressed with his professionalism and attitude from start to finish. He was motivated, clear in his communication, and provided a fair price compared to other quotes I received. Zan and his team carried out work in my back garden, where they levelled the ground to match the house floor level. The job involved removing a significant amount of soil and ensuring proper base preparation, including full waste removal. Everything was done efficiently and to a high standard. It was clear from the outset that Zan is an experienced builder who knows exactly what he is doing. He worked methodically, kept everything tidy, and delivered exactly what was agreed. Overall, I’m very happy with the work and would confidently recommend Zan and his team to friends and family looking for reliable and fairly priced garden or groundwork services.

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.

What to ask a Redhill extension builder before hiring?

Before hiring an extension builder in Redhill or extension building company in Redhill, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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.

Will my home extension meet all building regulations and planning requirements?

Your Redhill extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

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.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Redhill extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
