We couldn’t recommend Josh highly enough after our kitchen diner knock-through and kitchen fitting. Even when we changed plans last minute to include an additional knock-through into the lounge, it was handled seamlessly and completed within the original timeframe. Josh was reliable, easy to communicate with, and had a great system in place so we didn’t always need to be on-site. The whole process felt smooth and stress-free. A truly professional service with excellent customer care.
It’s rare to find such high levels of professionalism and customer service, but that’s exactly what we experienced with Josh and the Key Developments team. From initial discussions and expert advice to detailed costings and clear timelines, everything was handled with clarity and care. Communication was excellent throughout, and we felt completely confident leaving the team to carry out the work. The final result exceeded our expectations. We’re so pleased we chose them for our home project.
We used Josh for carpentry work at our home and wouldn’t hesitate to recommend him for projects of any size. His pricing was clear and accurate, and he arrived exactly when he said he would. The work was completed to a very high standard, with great attention to detail. Having also seen his work on larger projects, it’s clear the same level of quality is maintained throughout. A reliable and skilled professional.
As a busy architectural practice, working with Key Developments across multiple projects has been a great experience. Their support from the design stage through to completion has been invaluable to both us and our clients. They bring a wealth of knowledge to the team and are always willing to go the extra mile. Their involvement helps ensure projects achieve the best possible outcome. Clients also benefit from a high-quality finish at a competitive price.
We used Key Developments for our knock-through and kitchen renovation and couldn’t be happier with the results. Josh and the team were fantastic throughout, with excellent communication and attention to detail at every stage. The whole process was smooth, and the final finish exceeded our expectations. We’re extremely grateful for their hard work and professionalism. We wouldn’t hesitate to recommend them or use them again in the future.
I recently decided to open up my kitchen into a kitchen diner and was recommended Key Developments through a friend. From the start, Josh and his team were excellent, patiently answering all my questions and guiding me through the entire process. Communication was clear throughout, and the team were always punctual, polite, and respectful in my home. They made a real effort to keep everything clean despite the scale of the work, and the pricing was very competitive. The final result was spot on, I couldn’t be happier and would highly recommend them.
Josh at Key Developments recently completed a full refurbishment of our flat in Eastbourne, managing the entire project from start to finish. All trades were coordinated seamlessly, allowing us to carry on with our daily routines while everything was taken care of. The team proved to be reliable, trustworthy, and highly professional throughout. The project was completed on time, within the agreed budget, and finished to a very high standard. The property was handed over in pristine condition, and we would highly recommend their services to anyone considering a full refurbishment.
