Extensions- 3 Aug 2020
We worked closely with Harpreet, our Architect and Building regulations to achieve the dream kitchen and living space. It was a lot of work and sometimes we thought it would not finish or look how we wanted it. But Harpreet came through in the end and we are pleased with the work that was done to complete our single storey extension.

Groundwork & Foundations- 10 Oct 2025
Always a concern hiring someone you don’t know, but from the beginning Charlie has been excellent with communication and job started on time and finished on time. The guys were polite to our neighbour and very careful whilst using her access for our job. Very well priced and they were content to take the job on with difficult access where others clearly priced themselves out of the job or let us down. Would highly recommend.

Carpentry- 14 Jul 2026
I had Michael build an MDF book case in an old boiler cupboard. After agreeing on a price, Michael measured up the next morning, prepared all materials offsite, and then returned to install the bookcase the same afternoon. Bookcase was completed within 48h of job posting and the work was excellent.

Plastering- 23 Nov 2025
Just had all my plastering work completed by Callum, a full Bathroom ceiling and lots of new electrical chases in 3 x additional rooms. Callum replied to my advert within an hour and he came and viewed the work and we agreed a rate within 2 days. Callum was very punctual and started work straight away by covering all our floors and carpets with plastic protectors. Callum was very polite and worked extremely hard all day without stopping, he also plastered in some additional areas adjacent to the areas that we agreed in the quote, which was great. Callum cleaned up and hovered in all the rooms when the work had been completed and left our house spotless The Finish of the plaster is fantastic and smooth. It’s a great job, well done and thank you. I wouldn’t hesitate to hire Callum again in the future and I will be definitely recommending Callum’s services to family and friends.

Joinery & Cabinet Making- 10 Apr 2019
What a great lad, came over in the evening to do a site visit and came back promptly with a very competitive quote. I had to delay start briefly as I had no labour to help me remove old roof. Liam stepped into the breach and helped me with this. The following week he was there on time and ready to go not phased by slight delay because of weather & unseen snags with levels, sorted by my bricklayer another My Builder member. Liam will work well and safely on his own with a full kit of his own professional tools and his output is tremendous. On the first morning of deck job I had to go out for a while,I returned and was amazed at what he had achieved on his own, we are talking 5mtr 9" x 2" beams lifted up onto a structure and fixed. At all times he worked in a seamless professional manner, with a positive plan for the job, discussing any unforseen snags with an appropriate solution before overcoming them. Liam was always polite and courteous carrying out a marvellous job in record time for me. I have other jobs that I would not hesitate to employ Liam on as soon as he is free I can be fussy with my jobs, my background was Maintenance Manager at a London Uni and I have exacting standards. Liam met all my criteria. Don't be put off by his youthful looks, this is one good tradesman with old school skills and ethos. My long term friend who did the final roof cover, a specialist Flat Roof Contractor for 40 years+ commented on what a good roof he had built.

What to ask a Witham extension builder before hiring?

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

An extension builder in Witham 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 Witham 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 Witham?

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 Witham 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 Witham 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.
