The work was quite a big project and went really well with minimum disruption. They carried out the building of a single storey extension to the house and a new brick double garage. They also included the full renovation of the existing house. New floors & ceilings, added a new en-suite , returned 2 bathrooms, new fitted kitchen, electrical rewire, plumbing and left the work in a completed beautiful finish, the work was very well managed and more than happy with the workmanship, would definitely recommend.

The goods were moved but there was no careful consideration when the items were moved across. It became very difficult to reorganise everything.

Removal of existing conservatory and erection of single storey extension across the full width of back of the house . Including pitched roof with sky lights, patio doors and window to rear and side. Existing rear doors and walls were also removed. Throughout the build I was regularly consulted on progress, any issues were discussed and alternative products sourced ( roof windows) The work was completed to a very high standard, any delays down to weather issues were always discussed .every week I was aware of the plan of work for the following week. Mr Anderton was very professional and reliable throughout the build.

Bricklaying- 28 Feb 2016
After receiving a quick and competitive quote from James Walker in response to my advert on My Builder for a garden wall I appointed James to the job which was completed quickly and to a truly excellent standard. It is clear that James and his colleague are both highly skilled and professional. They were happy to answer all my queries and a pleasure to deal with. I would not hesitate in recommending them, they even cleared up after themselves. Very happy customer indeed, many thanks again guys. Best wishes, Billy

Extensions- 15 Aug 2022
I had a good initial contact and they came out to do a first look pretty quickly. Wanted quoting on an extension, porch, driveway and side wall. In the end none of these jobs happened. A good experience to begin with. Porch - needed an architect (recommended by the builder), which took a couple of weeks to come and look then a few more weeks to get the drawings back to me. In the end, was too complex/costly due to the roofline. Fair enough - but took way too long to get to that answer. Extension - Initial 'rough' quote was very reasonable, but getting them to actually do a costed up quote took many weeks. In the end, the quote was >50% higher than the rough quote (scope of work hadn't changed). Driveway - Visited 4 times for this job. On 2 occasions, just didn't show up and couldn't get hold of them by phone. All of a sudden they came back 'online' and after 2 more visits, a quote came which was more than x2 the original rough quote. I appreciate cost of materials has increased but double was just too much. Side wall - Based on the other jobs being so difficult to progress, we decided to get someone else to sort it => 2 weeks after enquiry, the wall was built. In the end, we lost months for nothing and decided to not bother with 3/4 jobs. It's a shame, because they seem like a good bunch of lads and their references/pictures look great, but clearly have either too much work or need to hire someone to manage their time better.

Landscaping- 26 May 2020
Dan has done a couple of jobs for me recently and I would highly recommend him. I hired him initially to lay a new patio for me, and he did a fantastic job - I couldn’t have been happier with the results or his professionalism/ attention to detail. Consequently I hired him to lay my wooden floors on the ground floor of my house and, again, he did a superb job. I have already warned him I’ve got a few more jobs for him later in the year - a man of many skills!

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

An extension builder in Barnsley 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 Barnsley 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 Barnsley?

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