Conversions - General- 23 Aug 2021
We converted our garage into a Garden Room and side shed and employed Oakspan for the job and are delighted with the outcome. Kevin and his team turned up promptly each day and as a result of their impressive work ethic the job was completed in a short space of time. They always left the site tidy at the end of each day and Kevin was good at providing suggestions/ideas of what we could do. I would certainly employ Oakspan again for future work and would thoroughly recommend them.

Groundwork & Foundations- 7 Jun 2026
I got KDM in to install a 75sqm concrete base and was very impressed with them for a number of reasons. - Firstly, their work was excellent. The finish of the base was excellent and they put a lot of effort in to get things perfect. - They were reliable. They showed up when they said they would both for estimates and to actually do the work. Sadly I cannot understate how rare this is today when working with contractors. Communication was excellent. - They're very honest. They gave me a quote based on my requirements which was a little high but manageable. At the end they came in under budget and gave me back the difference. All in all I would be very happy to both have KDM back for more work or to recommend them to anyone else.

Carpentry- 13 Oct 2018
Kenny completed 2 jobs promptly and on time. His estimate of time was spot on. The work was to a high standard. I’d have no hesitation about employing him again. In fact he will be my first choice for joinery work in the future. He found a solution to a tricky problem with the trap door hatch. He did this quickly with little fuss. We are very grateful. Thanks

Roofing (Pitched)- 26 Apr 2017
Job was done promptly and in a high standard. George was not lazy coming out in a weekend just to show me sample tiles to choose from. We decided to hire Smart Group, meticulously ruling out the others not only based on price, but way of their communication, professionalism and pride in their craftsmanship. We now have a beautiful watertight roof with insurance backed warranty. Even our special needs have been fairly priced and satisfied. We hope to hire Smart Group again in the coming years to do our insulation, guttering or whatever investment we think worth investing in our house. I recommend George for all my fellow perfectionists.

Kitchen Fitting- 27 Nov 2020
I was thoroughly impressed with Craig's work from beginning to end - he met and exceeded my expectations in all aspects of what turned into a fairly complex project (overhauling and fully refurbishing an 1800s tenement flat). Craig and his guys at CJF Solutions had a strong team of high quality contractors which they used to support the specialist parts of the project, and I was very pleased with the standard and finish of work across the board (including plastering, plumbing, carpeting etc). I was particularly pleased with his eye for detail, including making some helpful recommendations such as on how to tile the bathroom (which now looks MUCH better than the wet walls I originally suggested, and has been beautifully fitted out). Furthermore, Craig is easy to communicate with and very quickly grasped my requirements, meaning I was able to step back from the day-to-day detail of the project and trust him and his team to get on with it. In fact I was only on-site once over the course of the two month job, yet was delighted with the finished product. I have no hesitations in recommending Craig to others - I already have - and hope I will work with him again in the future. Thanks team.

Landscaping- 22 May 2026
Right from our 1st meeting I knew Iain was the right person for the job. He explained what he was going to do and how long it would take. Rain did delay the job for a week but Iain was in constant contact keeping me updated. Iain is your old fashioned typical trades person, turns up at the crack of dawn raring to go and just gets on with it. Im delighted with the work Iain has done, I would hire Iain again without hesitation and srongly recommend him to people I know. Thanks Iain
