Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez

Architecture- 20 Nov 2016
This is the first time we are carrying out an extension work at our property. Sean worked with us from a very early stage, prepared the drawings, coordinated with the council and ensured that we received the building approval on time. He was always available to advice us (when requested) on design challenges, choosing installers and material choices which we found very helpful. We are very happy with his work and thoroughly recommend him.

Extensions- 22 Oct 2018
Choosing MM builders was the best decision we could have made. Initial meetings: They took time to ensure they understand our work. They never complicated matters nor tried to hide things in any fine print and provided us with a estimated schedule and explained we would be kept up to date at all stages. Works: Their knowledge and work ethic is amazing and is reflected in their work. They gave us confidence and built trust very quickly. Always willing to go the extra mile and used their expertise to help us rectify issues or make suggestions in areas we would have never noticed ot thought of. Sam, Ross, Bill & Harry were so pleasant to have around the house. They were very conscious of the 3 young children in the house of which one has additional needs. They minimised disruption which is very difficult when doing major work in a areas and were always friendly and polite. We had no issues in having them inside our property which is very important when completing works taking just over 5 months. They work with specialist tradesman (tiler, plasterer, etc.) who are equally good at their trades. MM were very professional when it came to liasing with Building Control and made sure they were involved and visited at all key points. The aftercare we received was as good as we had received throughout the process. I have no hesitation in recommending MM for any building works. If I was to ever undertake any works in the future, it would be by them and only them.

Kitchen Fitting- 31 Jul 2019
Can't recommend this guy enough! Pat is a professional from start to finish. He came to quote me for a complete kitchen refit, within a few days he had emailed me a detailed quote and we agreed a date. My kitchen came with many unforeseen problems and challenges but Pat rose to them all. Aside from being a skilled carpenter and a skilled builder he is a great problem solver. He is reliable,trustworthy and very approachable. When I was getting stressed out he would calm me down and reassure me that everything would be ok. Sounds silly but my kitchen issues would have stressed a saint out! To summarise, my kitchen has turned out beautiful! Pat has done the work to a very high spec and gave it the wow factor! I absolutely love my new kitchen and am so happy that I chose Pat to come and do it for me. Look no further!!! Hope he posts my before and after pics on here and you can see for yourselves!

Latest review:
Ionut and his team helped me with the garage conversion at my house. My initial plan was to utilise the garage as an office space. In the initial meeting, Ionut suggested utlising the space to build a guest bedroom with ensuite as well as an office. I was slightly concerned about this as I always thought that the space was too narrow (3.1 meters) to accommodate all this. However, I am glad that I trusted Ionut’s team as the layout and design was better than expected. The extension is now the best built and most spacious rooms in the house. I would highly recommend Ionut and his team.

Extensions- 16 Oct 2023
Mariusz & his team are amazing, from start to finish they have been fantastic & we cannot recommend them enough. We met with a couple of builders for quotes & felt like our project would be in good hands with Mariusz, we instantly liked him & had a good feeling. He was happy to talk through everything with us, answer our questions & nothing was a concern or a problem, this continued throughout our whole project. Communication was faultless throughout, which in our past experience is unheard of & Mariusz was on site multiple times a week. The team were polite, hard working, tidy & professional. Andrew & Pavel were the main guys on our build & they were amazing. They arrived the same time every morning & worked so hard 6 days a week. We cannot believe how quickly & professionally they carried out each stage of the build, which ensured all timelines were met. There was no cutting corners, the quality of work was excellent, with many of our neighbours coming over to comment on their craftmanship, especially the brick work. Our local council building inspector assigned to our project was satisfied & complimentary of the build throughout, no concerns were raised. Doing any size home renovation project & finding someone you can trust & rely on can be daunting. However, Mariusz & his guys really are who you hope to work with. If you are looking for a team then look no further, you will be in safe hands. It's been an amazing journey & a pleasure to work with Mariusz. Thank you

What to ask a Croydon extension builder before hiring?

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

An extension builder in Croydon 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 Croydon 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 Croydon?

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 Croydon 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 Croydon 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.
