We used James and his team for our internal work and front and rear extension. After meeting with a list of builders, we found this service to be more personal and transparent. Others builders seemed to lack the communication skills to answer building related questions for those not in the industry. James however seemed to explain all details of the build to a high level, giving us reassurance. We would highly recommend Oakcrest Homes to others looking for a lovely new home design or build. The build was on time and James supported us with most decisions along the way, which included decorating, lighting etc. We plan to use the service again for future work. Thank you James and team for our lovely new home.

The job went exactly as he promised. Delivered on time, for the price he quoted. Oliver was professional from the outset and super helpful, as I annoyingly asked lots of questions. His workmanship was second to none, wholeheartedly recommended. Will be using again.

Extensions- 16 Apr 2026
I would not recommend this builder based on my experience. Instead of using crushed concrete they used soil to fill the house flooring for underfloor heating. 1 The project suffered from poor communication, repeated delays, and a lack of clarity around responsibilities. There were serious issues with the foundation works, which failed Building Control inspection and now require remedial engineering input before works can proceed. The site was also left incomplete and not in an acceptable condition. Despite substantial payments being made, key documentation, technical responses, and follow-through were lacking, leaving me to resolve major compliance and structural issues independently. My experience has resulted in delay, additional cost, and considerable stress. I would strongly advise others to ensure there is a detailed written contract, clear scope of works, and defined accountability

Extensions- 1 Feb 2023
We are in the last week or so of the extensive remodelling of the kitchen, utility room beyond plus bedroom upstairs. Mark Lomas and his team have been truly amazing, not just in exercising real building skills to blend the extension harmoniously with the existing Edwardian home but also in some imaginative problem solving as well. Costs have been spot on budget, save where I have caused additional work and fitting out, other than some unusual costs arising from some specialist joinery work which enabled the timber windows and doors to be exact replicas for others built 120 years ago. Honestly, I could not speak higher of the care and attention we have been given. I could get cross about the driving rain and the gruesome frosts and miserable cold, but that's a British Winter for you; Mark and his team certainly did not grizzle, and have stayed professional throughout. Circa £100k budget, so a reasonably size job and quite a risk for the builder - for my next project, I shall certainly use again in a heartbeat.

Loft Conversion- 5 May 2017
Artjom and his team have done a wonerful job on our loft conversion and house renovation. We are very pleased at the transformation. Although not the cheapest quote we obtained, they were highly professional, kept the noise down and cleaned up after themselves. We also added several other jobs to our initial quote and they undertook these as requested. It is important to keep a record of everything you ask to be done. They worked very fast and were able to complete everything within 2 months - it helped that our house was empty at the time, so they didn't have to deal with us living there at the same time as the works were being carried out. Overall, I would highly recommend Adam Renovations for any building works you need done to your property.

Damp Proofing- 11 May 2026
My experience with Samuel was excellent. He provided a professional, comprehensive, and high-value damp survey for my basement. The final report was very thorough, including a detailed technical assessment and numerous photographs that clearly explained the situation. What really stood out was his willingness to answer several follow-up questions regarding the specific remedial work he suggested. His expertise helped clarify that the issues were environmental rather than structural, which provided great peace of mind. Highly recommended for anyone needing a clear, honest, and professional assessment.

Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.
