Extensions- 18 Sep 2019
To start off with the job went reasonably well - we were happy with the workers and the progress. but when we neared completion the work slowed up we waited 3 months for a response from Jordan. we had an issue where his plasterer hid the plumbing access in the wall. - This cost us £500 to sort and re-decorate so we came to an agreement that this was fine and at the time i presumed that Jordan was going to sort out the building control. so we then chased and chased but obviously since he had his money he wasn't interested he answered the phone and hung up. so we called building control and there are 2 small bits to fix which are all due to his work not being up to scratch. obviously i will be paying out for this - so please be careful when using him and dont pay him until you have all of the documents as he will not resolve any issues after being paid. i have had 2 previous building projects and this was by far the worst experience going. avoid dont use him thanks

Repointing- 6 Sep 2017
Very happy with Josh's work. He removed several bricks, went to a reclamation yard to get good matches, set them in and repointed other bits in the same area. He was thorough, the work is of a high standard, and he cleaned up well. He also rigged up the old gate so the garden was secure until the new gate arrived. (By the way he didn't spend any time working one-handed while talking on a mobile for which I was grateful.) His charges are very fair. I have asked him to quote for a bigger job. Was slightly wary of employing someone who had just joined MyBuilder but glad I did.

Extensions- 6 Aug 2020
I’ve lost count of how many times we’ve said how lucky we were that we chose Bryan and his team to build our kitchen extension. The team went above and beyond to ensure as little disruption as possible, as we remained living at home whilst the work took place. During this difficult time, Bryan did everything possible to source the materials required to finish our build before our baby arrived and some how he managed it! His team were really friendly and the family miss having them around. They always tidied up after themselves before leaving too. What we thought was going to be a stressful time was in-fact the opposite. Bryan managed the whole process, kept us updated throughout and made sure the build remained on budget. The level of finish is of the highest standard, better than we could have imagined and I can’t recommend Concept enough. We will undoubtedly be using them again for work in the future. Thanks again to Bryan and his Team.

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.
