Bricklaying- 21 Jun 2025
I had a fantastic experience working with Ryan. He came out to quote promptly, and immediately impressed me with his technical knowledge and advice. He finished building a garden wall for me – over 10 metres long with an integrated seating structure – and then rendered it to a very high standard. Throughout the entire process, he was professional, communicative, and clearly very experienced. His pricing was fair, and I felt confident I was in good hands. The quality of the work is excellent – I’m extremely happy with the results and would absolutely recommend him to others. I’ll definitely use him again for future projects!

Have no hesitation in recommending Dan for carpentry jobs. He fitted a lovely new kitchen for us and his work was of a very high standard. All completed on time due to him working efficiently. Very clean and tidy in his work. He was very easy to have around and leave to work on his own too. He was happy to do extra jobs linked with our new kitchen- filling in an old doorway, and hanging a new door. Again done very well. Yes Dan's the man!! For your job too!

Extensions- 20 Nov 2019
Matt of Pro Build (East) Ltd. was instructed to complete a home extension on my Victorian Mid-Terrace property at the beginning of July 2019. Matt initially replied to my MyBuilder advert promptly, came to view the job within days and could start the next week (in hindsight, probably not a good sign). He started work on the Monday, providing a quotation and an expected completion date of 3-4 weeks later for the complete extension including removal of waste, plastering and external rendering. Throughout the build, Matt's communication was prompt, replying to emails, phone calls and text messages mostly within the same day. Unfortunately, on a number of occasions problems arose with the project and I was frequently to blame for certain aspects, for example it was my fault that the roof could not have slates because the roof was built at a low pitch - however the quote included slates? The quality of workmanship throughout the build was very varied, requiring Matt and his team to return a number of times to re-do work which was deemed unsatisfactory by me, other workmen and the building inspector. There is quite often a number of excuses for why work has not been done, or why it has been done to a low standard as opposed to correcting the issue without argument. In the end, the whole build took 14 weeks to complete and remained to have a number of snagging issues, I would not personally recommend this company for larger works such as this.

An extension builder in Suffolk 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 Suffolk 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 Suffolk?

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

How long will the extension take to complete?

Do you offer a guarantee for your work? Most Suffolk 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.
