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!

Restoration & Refurbishment- 17 Jul 2016
Valter was very impressive on his initial visit with some exciting ideas for the house improvements and we had no hesitation in choosing Happy Building above the other two building firms who quoted. Having signed off on the budget and scope of work, Valter's team of builders arrived. We were hugely impressed with the skill, experience and work ethic of the team; the fact that they arrived early each morning smiling underlined the "Happy Building" epithet; Jarek, the site foreman, had an especially cheery demeanour. The work involved stripping the walls back to bricks, removing walls, reinforcing foundations, plastering, extending the bathroom and removing one bedroom to create a large ensuite bedroom. The latter certainly would not have been done without Valter's vision and patience in explaining how it would look. We were able to deviate from the original plans without any problem which was very important in achieving the final look which we had desired. Valter was very careful in sticking to time and budgets which I had never experienced before with builders. The kitchen, bathroom, two bedrooms, living room and hallways were finished to the highest possible specification within our budget. There were one or two small features which, with hindsight, we would have improved such as door handles and shower fittings, however this was down to us not specifying exactly what we wanted. These are very minor details and a tiny part of the overall picture.

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.
