Gary and Dan, the father and son, who run SIL renovated our house from September 2023 to August 2024-it was a BIG project in every way. Gary and Dan are very proactive, taking the initiative to identify, manage and resolve issues that may arise, with a keen attention to detail – our project manager was superfluous to requirements. They have a great little black book of suppliers and skilled professionals. We are thrilled with the finished result and would not hesitate to recommend SIL.
SIL took over a kitchen extension to our grade 2 listed house and a garage conversion to create a home gym 10 weeks into the project, from May 2022 to March 2023. They did a fantastic job of painstakingly putting right a catalogue of issues that the previous builders had left us with, as well as innovatively coping with the surprises that an old house threw up. From start to finish they were highly professional and proved to be collaborative problem-solvers. We are thrilled with the end result and wouldn't hesitate to recommend them.
SiL recently completed the: extension, reconfiguration, total refurbishment of the original house to a very high standard of finish. The SiL core team and their selection of associated trades worked well with our architect and designers to create a home we are very pleased with. We have no hesitation in recommending SIL
We used SIL for a full house renovation and extension, and couldn't be happier with the results. They transformed our home from a 2-bed into a spacious 4-bed, and the quality of the work throughout has been outstanding. From start to finish, the team were professional, reliable, and easy to communicate with. Every stage was handled with care and precision, and it's clear they take real pride in what they do. The attention to detail, craftsmanship, and overall finish is excellent. We highly recommend SIL to anyone looking for quality building work. A fantastic experience from a great company.
