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.

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.

I originally contacted Joe from Orama to fit a new kitchen for me. When he came to give me a quote, I hadn't yet chosen what I wanted. He really took the time to make several recommendations and so I decided to go ahead with him to design my kitchen fully and fit it. The team were so easy to work with and most importantly respectful in my home! Their attention to detail is second to none. He really understood the style I liked in one conversation. The finish is flawless. I highly recommend them!!

Extensions- 23 May 2022
Ceca Developments have done an outstanding work on our side and rear extension project, and we would definitely recommend this company. Firstly, they have offered a really competitive quote for the work and have been very transparent and detailed in regards to how long it will take to complete the project. Sebastjan has been a pleasure to deal with and was very helpful during the project, providing honest and useful recommendations and being available every time we needed anything. All the work has been completed to a very high standard and to the agreed timelines. We did not have to worry about anything during the whole project, which made this a very pleasant experience.

What to ask a Dunmow extension builder before hiring?

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

An extension builder in Dunmow 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 Dunmow 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 Dunmow?

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 Dunmow 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 Dunmow 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.
