Conversions - General- 16 Mar 2016
I hired Smiley Building Services for the renovation of my 3 bedroom Victorian house in South London and I am thrilled with the work they have done. The project was large and included structural work, the installation of a brand new kitchen and two bathrooms as well as electrical work, plumbing, some carpentry work, plastering plus general decoration. I searched for a while before I found the right team but I really liked Smiley's 'can-do' attitude and reasonable quote. He and his team worked very hard to get the job done in 4 months and battled some horrible weather conditions. Smiley was always easy to get hold off and although there were a few communications problems to start with these were easily ironed out. I would definitely recommend him and will certainly be using him for all of my future projects. A great find!

Mick did a good job for us. He worked long hours to get the job done, and was able to turn his hand to a whole range of things, including plastering and decorating. The basic carpentry and construction was well and neatly done, and we’re very happy with the end result. The job ended up taking longer than either of us expected, but that was due to complications with some of the tasks, plus some extras, and was therefore not Mick’s fault. We were able to amicably agree an additional payment on top of the original quote to cover Mick’s time. Recommended.

Plastering- 16 Mar 2020
Almed and his team came over to see the two bungalows and gave me a quote and was more reasonable than other quotes I had previously. Almed started the job and stated exactly what he was going to do from the beginning to the end of the job. He is a very professional and knowledgeable person and he and his team did a outstanding plastering job on my two bungalows and I’m very happy with the job and will highly recommend him for future projects.

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.

I am delighted with my new cast iron Victorian air bricks with grills! Jacek took the old ones out and inserted the new ones. The job is extremely neat and the area left completely immaculately. A few neighbours have taken his number for more work. You will find Jacek extremely polite and amiable, professional, hard working and very knowledgeable about his particular trade. His price was competitive and I would have no hesitation in recommending him. I will be hiring again for other structural work. A great professional find!!

We have been working with Derek Borkiewicz (Sebek Construction) on a renovation of a garden flat in Little Venice since last autumn. We needed to completely restore the whole flat, including the garden. This was our second renovation project and by this time we knew what we wanted to do, which mistakes to avoid and what to pretend from a qualified builder. We will never stop saying how lucky we have been to find Derek and his team! Derek is not only a professional builder who is very careful to the smallest of the details. He is not only a very good project manager who is constantly checking the work of his men. Derek is a friend who takes on board a project like it is his own project. He suggested the most convenient and best solutions for any problem we came across during the works. There wasn’t a time when he didn’t know what to do to solve a difficult situation (and there are lots of small and big issues coming up in a renovation work) no matter how complicate they were and how long it took to solve them. His availability and his courtesy are incredible above all in a fast running city like London. This is priceless to us. His hard work can be seen in the wonderful result we reached with this garden flat. If we ever decide to work on another project we won’t think twice about working with Derek once again. In fact, now that we found the perfect man to work with, we are looking forward to finding another renovation project to work on! Monica

Calvin and Jimmy have been absolutely brilliant, and have been the best builders that I have employed. So much so, that I have subsequently asked them to do a whole shopping list of things, from fitting a kitchen to removing an old fireplace. They are always on time, very polite, kind and knowledgeable. Best of all, they get things done quickly without any fuss. Calvin has been invaluable in sourcing items from trade required for the latest project, and clearly talks through requirements of any project. I would very happily recommend them for the excellent value they offer and fantastic level of workmanship.
