Bricklaying- 9 Dec 2025
We agreed a start date for the work, and from the beginning communication was slow and required constant chasing. Alan sent me a full materials list, which I purchased on the understanding that the job was proceeding. As the start date approached, I repeatedly tried to confirm when he would arrive so I could organise my day and be available to help on site, as we agreed for me to b involved as a labour. Despite reading my messages, he stopped responding entirely. I sent multiple messages and tried calling several times over the course of a week and received no reply at all. The job never started, and I was left with purchased materials and a significant amount of wasted time. I cannot comment on the quality of his work as he never turned up, but based on the communication alone I would strongly advise others to be cautious.

D.Baker Building and Maintenance Services LTD
No reviews yet
Extension Builder in East Sussex
I left school in 2006 to begin my career in construction, working with my Dad and Uncle who was the managing director of TPCT (The personal construction team). Here I learnt many of the skills I work with today, kitchen & bathroom installation, plastering, plumbing, painting & decorating, tiling and carpentry. Having earned my stripes over a 6-year period I decided it was time to set up my own business which eventually evolved to become the company I have today, D Baker building and maintenance services. I really do love what I do and I get so much satisfaction from delivering a high quality professional service to my customers, whilst giving real value for money. I have very high personal standards with my work and take real pride in what I do. This I believe is reflected in the outcomes I achieve, the positive feedback I receive and also from the recommendations that come directly from my customers. If you have any queries about what I do or want more information then please do give me a call to discuss

Bricklaying- 10 Sep 2026
The job was to restore a 1920’s or earlier exposed brick fireplace where bricks were missing and/broken in the middle of the stack. Stephen did an excellent job of repairing the old lime pointing which he chiselled out by hand until he reached the sound lime and having found and cut suitable/matching bricks, he painstakingly filled with new lime. Looks great now and is sound. I couldn’t be more pleased with his work and he is a thoroughly nice person whose prices are reasonable. Definitely recommend.

What to ask a East Sussex extension builder before hiring?

Before hiring an extension builder in East Sussex or extension building company in East Sussex, 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 East Sussex?

An extension builder in East Sussex 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 East Sussex 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 East Sussex?

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 East Sussex 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 East Sussex 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.
