My partner and I are so pleased with the extension work which Paul & team carried out, not just what was done but also the way it was done. All of the team were great - they turned up when they said they would, and simply got on with their work, They were all polite, friendly, helpful, conscientious, and made several suggestions to improve the finished work. They frequently checked on details with us as the work progressed to ensure that we was satisfied and our needs were met, we was extremely impressed with how they understood & handled our neighbours, will definitely use again in future projects!

Groundwork & Foundations- 21 Jan 2023
Came on a Saturday at 7 in the morning in 0 degree weather to sort out my rainwater gullies. Managed to rod and clear them in the space of a few hours whereas I had had a number of chancers quoting bonkers amounts to redo the whole system. Knows what he’s about, is on time, and professional.

Firoj and his team renovated a bathroom for me in March 2015. He gave me a fixed cost for his labour and what turned out to be a very accurate estimated cost for all the parts/materials at the outset. He also gave me a completion time of 9 days with 1 extra day for 'spillovers' and 'unforseen delays'. He finished the job at exactly 9 days and still came around on the 10th day to see how everything was working. The quality of his work was excellent, to say the least. He attention to detail was admirable, as was his commitment to delivering a finished product that would last several years. This focus on detail and longevity is something that really sets Firoj apart from other builders, who often see such jobs as just another task to be completed before moving onto the next job. I have no hesitation in recommending him. Several months later my bathroom still looks great and everything works.

Latest review:
Florin extended and completely refurbished our 4-bedroom semi-detached house. This included extensive steelwork, underfloor heating, complete re-plumbing and rewiring, excavation, and an entirely new slate roof as well as varying extensions up to three floors high. I cannot say enough good things about his workmanship, professionalism and reliability. His workmanship makes a perfectionist like myself happy. He is also completely professional: even with our difficult neighbours he was always courteous and understanding, and even helped them sort out issues at a moment’s notice that had nothing to do with his building work on our property. And he is also thoroughly reliable. I cannot think of any instance where he committed to something and did not deliver — he even managed to finish all the work on our house ahead of schedule and on budget. We have been so happy with his work that we contracted him to build us a summer house as well, from scratch, and to complete revamping our front garden including elements of hard landscaping. Again he delivered flawlessly and we are very happy with the result. We also continually receive positive comments from people passing by and just seeing the front garden. We have used several other builders in the past on other properties, including far more expensive ones, and none compare to his level of competence, attention to detail in his workmanship, his complete professionalism and thorough reliability. Now that we have found Florin, we will never look for another builder again. I just hope once others experience what he delivers for themselves he will still have some availability for us in the future!

Restoration & Refurbishment- 21 Jul 2025
Despite the fact that CRI was a new member on the app with very few reviews, Jon came across very professional and accommodating and priced the job swiftly and fairly. I took a pun and awarded CRI the job. It took circa 2weeks and during this time Jon and the team where exceptional. In order to catch up and meet deadlines they were more than happy to do full weekends and always left the site clean and tidy. During the works, the team always kept me in the loop with photo updates on whatapp and next steps. I would highly recommend CRI.

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

An extension builder in Charterhouse 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?

What experience do you have with similar extensions in Charterhouse?

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