RJ Priest General Maintenance
Rating: 5 out of 5
Extension Builder in Buckinghamshire
Since 2010 I've provided building and maintenances services to my clients from painting and decorating, fitting kitchens and bathrooms throughout to medium size extensions from ground works to fully finished builds. 99 percent of my work is via recommendation or repeat customers. I tend to take on works which are of an interesting nature or require greater attention to detail. If this fits with the type of project you have or the sort of tradesman your looking for then we may be a good match, so give me a call as I'm always happy to work with like-minded clients. Best regards Roger Priest

I am so pleased with the standard of work and could not recommend Blinding Builders more. My bathroom has been transformed and finished to such a high standard Michelle gave the initial quote and she was very friendly and helpful .and gave some good advice.

Simon has transformed our garden area using a variety of materials to create a paved, decked and artificial turf area that all link together. Simon helped us choose materials to create the right effect and impact e.g large porcelain slabs and helped us withe design of the decked area and planter. He suggested making the decked area larger and thankfully we took his advice. Simon kept us informed of deliveries and working times and overall, we are extremely pleased with the job.

Landscaping- 12 Jan 2021
Brady and the lads did a fantastic job building me a fully insulated rendered block garden room. I went for Ellis Phillip because both Brady and Andrew are genuinely decent and trustworthy guys. They were tidy from the onset and even covered my whole driveway in a layer of board and plastic sheet before the job started to prevent and damage and mess. Good quality of work and finish. Brady uses the same teams (eg plasterers, electrician, etc) for his jobs and they all work well together and communicate all aspects of the job with each other which helps alot. Nothing was too much trouble - we made numerous last minute changes throughout the job and he was happy to accommodate them. Job finished in a decent time scale. We're extremely pleased with the finished result and would definitely use again and recommend to friends and family.

I hired Dan to give me a hand on an extension, he was very knowledgeable and knew how to set out and overcome problems which many bricklayers don't know how to do. He was hard worker and a very nice man as well which is a bonus. I would not hesitate to recommend him if your looking for some brickwork to be completed.

Extensions- 19 Dec 2017
Richard and Andrew were excellent from beginning to end. The estimates were accurate and they came in on budget and finished on time. The work was done to an excellent standard with great attention to detail and no cutting of corners. They were considerate and helpful and tidied up at the end of each day. They were also friendly and we had many comments from our neighbours about how friendly and pleasant they were. They were also very helpful with last-minute changes that we needed and made suggestions for how things could be done better and more cost effectively. They even looked after our dog during the day, letting her out when we were not home. I would recommend R. Naylor Construction if you need a good job done to a high standard by someone who is friendly, knowledgeable and considerate.

What to ask a Buckinghamshire extension builder before hiring?

Before hiring an extension builder in Buckinghamshire or extension building company in Buckinghamshire, 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 Buckinghamshire?

An extension builder in Buckinghamshire 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 Buckinghamshire 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 Buckinghamshire?

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 Buckinghamshire 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 Buckinghamshire 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.
