We honestly felt like we hit the jackpot with Colin and Kirk! They arrived early each day, worked quickly but with great attention to detail, and brought fantastic ideas to the table. Nothing was ever too much trouble. One of their standout strengths is communication — Colin kept us informed every step of the way, which made the whole process smooth and stress-free. It's rare to find that level of care and clarity in the building trade. We’re absolutely delighted with the results

Lee and Chloe were fantastic. They built a decking area for us which has transformed the garden. The quality of their work is excellent and their work ethic is superb. They offered great advice and ideas, which often saved us money. I would have no hesitation in recommending Lee and Chloe, lovely people, excellent quality work and great value.

Hired Ian to Build a single story extension and install new kitchen and downstairs shower room . Crew were very pleasant and very helpful in planning the the job ahead of them. Very pleased with the work carried out looks amazing Having to put up with an awkward neighbor didn't deter them from doing and completing the job. The price put in was very reasonable. When the work was ongoing the area was always left clean and as tidy as possible . I would recommend Ian 100% , and would use him again.

Mr Rob Robinson has come to my house to repair a leak in the roof in August 2018. Since August 2018 we have had to call Rob number of times. The roof is sill leaking and he is refusing to refund the money even tho I have offered £100 for his trouble to date. I have further damage inside the house due to the leak.The communication is poor and no sense of customer care. At this stage following few attempts I do not trust Rob can fix the leak and I hope he can do the right thing and refund the money paid!

George responded quickly to my request, gave a very reasonable quote, did a really quite tricky and complicated job above a conservatory, to fix cracks in the pebbledash of an external wall, and seal all around the windows. A fortnight later he re-plastered internally. George gives the impression of being somewhat chaotic! But he is extremely experienced, knows what he is doing, and actually did a very good job. The timings and quote agreed to were respected, he was polite and cordial, and communicated well

IINOVA DESIGN LTD

Cellar & Basement Conversion in Malmesbury

Hi, my name is Sheridan – new to Ratedpeople and would like to get more reviews. Friendly approach with clients to fulfil all their work. Involved in all aspects of building. We provide a quick turnaround on quotes at competitive rates. We always keep a clean and tidy site. Customer satisfaction is our main priority. Started in building Sept 2016. Previously a Production Engineer, but decided to change to a job that was more hands on with a good social connection. I chose building work – so I have a good balance of technical skills and practical skills gained over many year of working on Builds. My first two builds were complete builds from the ground up, so I had to seek out and get trades on-site to complete work I didn’t have the skills for. Over time I have carried out all sorts of work over the past few years from Setting out a site, Groundworks, Blockwork, Construction, Timber work/studding, Plaster boarding, Fitting kitchens and Bathroom, as well as Wooden Flooring and Tiling, and of course decorating. I leave plumbing, electrical work and plastering to the trades ( and have good contacts ) – but I have a good eye for detail but enjoy fitting kitchens, bathrooms, doors, skirting, and painting.

Latest homeowner review

Reviewed by Paul on 8/8/2025

Sheridan was hired in Apr - initial communication and detailed quotes gave confidence however, once he started the job it became clear that his work was average at best and more honestly that of a weekend DIY’er. The job ran well over and he has yet to actually finish it (about to start claim against him for costs to finish job). His quotes where he contracts out to the trade aren’t accurate and he doesn’t check the cost with them so some very expensive surprises. Avoid at all cost.
