Groundwork & Foundations- 1 Sep 2025
We hired James for 5 days digger work in our garden and he was brilliant, we don’t know what we’d have done without him. He did so much extra for us, from removing a tree and its roots to lifting off and rehanging very heavy gates. We’re really grateful and hope that we can use him again for ground and building works.

21st century plastering
Rating: 5 out of 5
Extension Builder in Broxbourne
I have been a self-employed plasterer for 25 years, working on domestic and commercial projects of all sizes. Each job, large or small, is treated with the same care and consideration to ensure the best finish and full customer satisfaction. I treat customers and property with total respect, and will always leave each location clean and tidy on completion. If, on inspection, I find that walls and ceilings are prone to movement, and to prevent future cracking, I can use rolls of Fibremesh in my first coat of plaster. I have found that this technique, developed over the years, has proven better than the standard ‘skim’ method, and gives stronger, long-lasting results. I am happy to provide advice even if I am not directly involved in the work. Once plastering is complete, I can also offer an excellent painting and decorating service, as well as guidance on achieving the best possible result. I am also more than happy to discuss with you, and to help you, bring your own ideas to life within your budget. Additionally, I have also worked on many Grade ll listed buildings throughout the country, and have enjoyed using my skills to restore them sympathetically to their former glory. Should you have work or projects, large or small, in any of the above areas that I can assist you with, I look forward to hearing from you. WILLIAM VAUGHAN

When Mr Nesimi came to undertake a pre-assessment for my front wall, he came across very professional and genuine and very honest about the work needed doing. He even suggested some changes to the work to reduce cost. The quote he gave me for the job was very reasonable and he was able to slot in my job within a week and arrive sharp on time at 8am and got on to the job straight away as I had a busy day at work for me to attend to. I notice that right from the start he was very clean and meticulous with the work and his job was of a very high quality ( compared to a job I had done by another builder 9 months ago). My neighbours also noticed this difference and were praising Mr Nesimi’s work. I would definitely recommend Mr Nesimi for any construction work as I felt he was very professional, reliable and honest and most of all the work was of high quality. I will be certainly calling him for my next job, most likely the driveway resurfacing and the attic conversion within the next year.

Extensions- 24 May 2018
Having been let down by my original builder, I posted my requirements on MyBuilder.com. Simon Cranstone (Simon) responded promptly and based upon my scope of work provided an initial Projected Cost (PC) budget. The project, a house refurbishment with an additional single story rear extension was clearly no problem and a "turn key" project was agreed. I was impressed by Simon's ability to explain costings albeit PC at the outset and the realistic 10-12 timeline for completion of works. My original architect was replaced by another on Simon's recommendation ensuring that the relevant Thames Water and Building Regulation/Control exchanges/requirements were met. Simon or the builders onsite dealt professionally with all the challenges arising whether it was unexpected drain works, appalling weather and even business as usual neighbour concerns. Although the PC budget was exceeded by some 30%, these were as a result of Building Control requirements and project scope creep by myself. The project was delivered on schedule. At all times the professionalism and, craftsmanship of the builders in particular were a credit to SP Cranstone. I would have no hesitation in recommending them to do all building works and happy to provide any further feedback if required.

Alpha construction did a 2 storey side and roof extension, loft conversion, complete renovation, drive and patio for us. In short they took a dated 3 bedroom house and converted it into a modern 5 bedroom house. We invited over 10 builders to bid and Alpha supplied the most detailed quote and were the only one to meet each deadline. They were also always quick to answer questions. That level of customer service and professionalism was reflected in all latter dealings with them. They started on time, they finished on time. They updated us on a regular basis and found innovative solutions to unexpected issues e.g. inaccurate architectural drawings. They kept to budget and were transparent with costs. My husband particularly appreciated that they recommended value options or found lower cost solutions to our ideas. We also got access to a wealth of subcontractors. Ross put together a high quality team from the expected plumbers, electricians etc. To the unexpected such as window vendors / kitchen suppliers. All of which gave great value and high quality services compared to alternatives we found ourselves. Everyone at the house was polite and conscientious, in fact neighbours have been asking for quotes since. Since moving in we've had a lot of people comment on the great finish of the work they did. The house looks lovely and I would be happy to show others thinking of using them. I have recommended them to my friends and that's about the best compliment I can give.
