Conversions - General- 30 Jan 2019
We recommend Paul highly and will definitely employ him again. Paul is highly skilled at what he does and he is very committed to the quality of his work. He ensures everything is done to a very high standard. He quotes accurately and his costs are reasonable. The breaking down and finishing of the wall between our kitchen and dining room makes our home looks great! He has good suggestions which we did not think about and which enhances the effect. We are really delighted with the quality, the speed and the aesthetics of the work that Paul has done for us. We will be asking Paul to come in to work on many other refurbishments to our home.

Plastering- 15 Sep 2025
I hired David Edwards for a project that was meant to take 6–8 weeks. Over a year later, the work remains unfinished despite me paying £5,000 of a £5,800 contract. Communication has been poor, with long absences from site and constant excuses. He repeatedly changed what my payments were supposed to cover, demanded money upfront without providing receipts, and some receipts later provided were for items I had already purchased myself. The workmanship is substandard — loose tiles, unfinished sills, poor grouting, paint smeared on windows, render already peeling, doors not replaced as agreed, and many areas left incomplete. He still insists the job is “finished” despite extensive photographic evidence proving otherwise. I now have to hire other tradespeople to correct and complete the work at further cost. In my experience, David Edwards has been unreliable, dishonest, and unprofessional. I would not recommend him.

Bathroom Fitting- 6 Jul 2024
Absolutely fantastic service. We had a complete bathroom renovation, including moving plumbing and Olympus gave us a great price. They were professional, friendly and the quality of their work was outstanding. They were very respectful of our home, very clean and worked diligently. They worked exactly to the timeframe they provided at the beginning and there were no squabbles over agreements. We will definitely be calling on Olympus to carry out any other work we need doing and highly recommend them to anyone.

Conversions - General- 9 Feb 2026
Ed and Shaun came the other week to re-plaster our kitchen as we were in the middle of having a new one, block off the pantry door and open up what was the pantry, under the stairs into the hallway, thus creating a small but very nice open area for storage. This also allowed us to have more room back in the kitchen. They had a high attention to detail with everything they did and took pride in their work. Would recommend them.

Conversions - General- 9 Oct 2024
S&B converted my garage and fitted a new kitchen. I was impressed by the level of attention to detail these boys made. The fixings to the fridge cabinet were not the supplied fixings from Magnet but a set of more robust brackets to compensate for the suction of the fridge door. Any requests made by me was met with a "yes". Their standards are high right down to ensuring that the cabinets were straight and level by using both Lazer and spirit level to ensure accuracy. I have already commissioned them to undertake the next area for refit. Can't recommend them highly enough. 5*+++
