What People Think About Us

When we were selecting a company to convert our loft in our three bed terrace, Adam came over and we knew straight away they were the firm for us. We just had “that feeling” you get when you meet people in certain trades that you can really trust. From then on, the whole build team were absolutely brilliant, professional and friendly. We were always kept updated with progress and any issues that arose during the build were professionally handled and resolved quickly. The whole team were excellent and the end result is absolutely stunning. We would highly recommend to anyone wishing to covert a loft space. It’s changed our lives in so many ways – thanks so much!.

Superb Company’ West Sussex Lofts created a brilliant loft space for us. The moment we met Adam and his company we knew that they were the right company for us. There was no sales pitch involved, it felt like an honest quote and very competitive. We did look into other companies but they seemed over priced. WSL took care of everything from the planning right up to completion. Ian and Brandon were our builders they did a brilliant job and went out of their way to complete the job on time. They went beyond the call of duty. We think the best part of the whole build was the way Adam and his team kept us informed on a daily basis what was going on and answered all our thousand questions over many mugs of tea. Any issues were discussed, agreed and dealt with promptly. Mike the Plummer and his services were great. Mike installed a combi boiler which has completely changed my life - who knew lol !! No more cylinder boilers for us. Mike installed the bathroom which we think looks fantastic. We particularly like the staggered approach to paying for the work. After each stage was completed Tasha let us know payment was due. Very clear communication. Thanks again WSL a personable and highly professional company - would recommend 100% by us.
A huge thankyou to Adam, Paul, Kevin, Tasha, Keith and Liam for sorting out our new loft conversion. The work was excellent and on time and budget. Myself and my wife can enjoy our new space giving our children more bedroom area. Many thanks again you were a great team.
