Kitchen Fitting- 24 Oct 2016
Kris, Gustav and their team have been absolutely amazing, cannot praise them enough. First of all - the job ended up being a lot larger than initially thought- as decided to replace old ceilings and flooring, walls -everything was uneven to start with. So took everything back to 'bare bones' and pretty much built it up again as a new house. New electrics, water pipes, completely new kitchen and bathroom. I really appreciate they were very straightforward with the estimated costs from the beginning - it did run slightly over budget but nothing too bad as had some contingency funds prepared. I would have hated to be quoted one price then half way through the project to discover it escalates out of control. Thankfully they are really honest and reliable. They were always easy to reach and replied any question I might have had in a timely manner. This was particularly important to me as I was between uk and us at the time so couln't be 'looking over their shoulder' so to speak. Last but not least the finish and quality of works is absolutely amazing! They couldn't have paid more attention to every little detail if it was their own home. For instance I remember last day of work when they were tidying up Gustav came back to put up door stoppers for me, completely on his own initiative. It's just a little touch but goes to show the dedication they've put into the project and care about the finished product.

Conversions - General- 3 Sep 2025
Big refurb of 1650 sq ft flat, plus building 2 additional ensuites. Initial quote seemed reasonable but then once in, costs started to rise exponentially. Some work was done well, like the building component and flooring, but finishing was poor. Painting, particularly of internal doors, was done poorly, without removal of fittings first, so lots of overpainting and insufficient prep and coats. Regrouting and redecoration of front and rear patios was done poorly, with weeds already poking through. There was damage to existing bathtubs and WCs by not protecting surfaces and pouring waste materials down the pan. Everything was an argument with constant demands for more money e.g. front door only painted one side as the other side not included under "paint door". Lots of "snagging" - I only have manual on/off control of heating and hot water as "smart" thermostat won't connect, there are odd water pressures through some fixings...and now there's a leak under one of the WCs...

Extensions- 16 Nov 2019
I was very lucky to find Cornel for my building work. His team were extremely hard working, efficient and respectful and the work was done very quickly and to a high standard. Most estimates for the build time were between 8 and 10 weeks - my work was fully complete in 6 weeks. Building control passed all stages of the work without any issues. He is equally proficient at the plumbing, electrics, flooring, tiling and decorating as the heavy building work, even restoring my garden so that it looked better than it did before the build. I am in a conservation area with close neighbours on all sides and Cornel minimised the disruption as much as possible and made efforts to keep everyone happy. His attitude to overcome problems and make sure that in the end you are a happy client drives his approach to the work. I had 10 builders quote for the job and Cornels quote was very competitive and the final costs were exactly as we had agreed. I had spoken to a number of his previous clients before going ahead and they were all very impressed with his work and had good experiences. It can be a difficult decision to choose a builder if you have no previous experience and given the potential for things to go wrong - but we made the right choice. I wouldn't hesitate in recommending Cornel and his team.

Kitchen Fitting- 31 Jul 2019
To say Nick is just a kitchen fitter isn’t doing his work justice, he’s a fantastic project manager and craftsmen as well. When we first met Nick he took 2 hours of his time running through all the options which was when we realised we were actually quite clueless! Although we hadn’t hired him at this point his advice was invaluable. We assumed this would mean Nick’s professionalism would mean he would be very expensive, this was not the case and he was actually a little cheaper than the other parties who quoted. Once Nick started it became apparent that he and his assistant Chow to great pride in their work and worked hard to get the job finished as quickly as possible to the highest standard. They left the site spotless at the end of each day. The result is a fantastic kitchen and flooring which we are extremely happy with. We are already thinking about the next renovation piece in our home and would love to use Nick again. Thanks Nick! Niall & Hannah

I had my double side and single rear L shape Extension which had kitchens and bathrooms with bedrooms. It was turnkey project and didn’t know them before but they are Pro Contractor as they got all planning permission approved with structural calculations. They completed work in time with high standard quality and regulations and got my certificates from council. I would recommend them as Pro builder all the time.
