Rodrigo and team at Loyalty renovated our house, fixing lots of minor issues across the house from wear and tear. They were very flexible and did a great job across the whole house inside and outside. We have had lots of compliments since they did the work of how well the house is presented.

Extensions- 1 Jul 2021
Great job done by Naim and his team. He expressed interest in the job as soon as I posted. If it hadn't been for some wet weather the job would have been completed much sooner in the timescale he quoted. There was one small issue some time after the job was completed. I only called Naim once and he arranged a day to come fix it. We're very pleased with the finish, we would give future work to him and also recommend him to friends & family.

Works consisted of hip to gable loft conversion under permitted development and a refurbishment of the first floor of a semi-detached house into a four bedroom/bathroom layout, including new windows, balconies, wiring and plumbing as well as sound proofing the walls. With 100m2 of works this was my first introduction to a major building project and I was worried by the horror stories I have heard about builders. From the outset Monika set my mind at rest, listening to what I wanted, making helpful suggestions, offering tips for instance on how to save on the scaffolding and always asking me when choices needed to be made. She took the trouble to ensure that I knew what was happening, with daily photos of progress without the need for me to climb scaffolding. I was working to a tight timescale and budget, which Monika understood, and even having accommodated a number of changes including some additions, the project came in on time and on budget. All of the workers on the site were very professional and the quality of the work and the attention to detail was exceptional. I have no hesitation in recommending Monika and her team - I went into this project apprehensive and not sure what to expect; thanks to Monika, I came out the other side delighted by and looking forward to working with her and her team again to renovate my ground floor.

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.

Not only was Ian's quote to do the loft conversion very reasonable, he was very reliable, tidy & very helpful when we had a difficult situation. The work was done in a quick time, when he said he was going to be on site he was, at no time did he let me down. The standard of work was excellent, I would recommend Ian & wouldn't hesitate to use him in the future.

Mustafa is excellent! He did a fantastic job on our bathroom - so much so, that when we decided on a more extensive construction project, he was our first call. He is communicative, friendly, and hardworking. All his team are sweet guys and they did a great job for a great price. I cannot recommend him enough.
