Demolition- 24 Nov 2021
We employed A.V Structures for the building of an external wall around our property, the removal of a garage and the installation of railings and gates. Throughout the 4 week programme we could not have been happier with their work. Arrival was prompt, their pace of work displayed energy and purpose. They were mindful of us and our neighbours and made sure the area was left clean and tidy at the end of each days work.in addition the workmen were courteous and kept us fully informed. Alex, the owner of the company, kept in close contact with us to assure himself of our satisfaction. He came on site at intervals to check that all was going according to plan. We therefore felt completely confident that quality and outcomes were important to him. Employing A.V Structures was a decision we were pleased to have made. We would use them again without hesitation and recommend them highly to anyone considering similar work.

Bathroom Fitting- 24 Oct 2025
We had 2 bathrooms refurbished at the same time by Romulus and his team over a 4 week period. Both bathrooms were completed on time and on budget. We were looking for 2 functional bathrooms, but ended up with 2 very high spec bathrooms within our original budget, and couldn't be happier with the high level of service and professionalism by all his team. We will now move forward and have his team refurbish our kitchen.

Extensions- 7 Feb 2020
I had installpro put an extension on my kitchen by knocking a lean-to and extending into that space, also completed insulation and roofing on the new extension and existing roof, this involved building new external walls, damp course membranes, plastering, new cast iron radiators were plumbed in, new electrical circuits and sockets, tiling, skirting, painting, new sash window fitted, new guttering and fascia and even a fitted kitchen bench was made from scaffold boards, which came out really nice. Marek was very professional and everything was done in a timely manner, no waiting around once things were agreed on. Always early every morning and working full days, even one of his team worked a Saturday to stay on the timeline. The quality of the work was very good, I was impressed with the roofing, proper insulation was used throughout, at the side of the roof behind the fascia too and new lead flashing was finished properly. The team that worked here were very clean, always using proper dust sheets and cleaning up at the end of each day. At the end of the job, final touch ups were made after consultation, to make sure I was happy with everything and then Marek saw that a proper cleanup happened and everything was completed on time and on budget as outlined at the beginning. I can recommend Installpro, and I will use them again for future work on my property.

Alton and his team at Bluelime have been incredibly helpful and enthusiastic throughout our design and planning process. From the start, Alton took his time to understand our needs and propose several cost-effective ways to improve my home and create more space for my growing family.

Gas Work- 7 Oct 2025
This provider took my money but never attended my property or carried out the work (a report on already completed plumbing works). All he had to do was write a report to say that the repair works were complete. On the day he was due to attend he never let me know he was on his way or that he wanted to come early morning. Then he went to a nearby apartment a few streets away and said he had attempted to come so it was my fault. Then he said he would do the report remotely I must send him pictures, after sending him pictures he said he wanted to visit site so we were back to him making an appointment which of course he really did not want to do. 3 months later no sign of my money or a very simple report that a child could have done. He also has not returned my money (£120). I can now see why he insisted he be paid in advance because he is a time waster with no confidence in his own abilities hence payment in advance, so that when he disappoints the customer he can still get paid.

Bathroom Fitting- 7 Jun 2026
Excellent service and outstanding workmanship! I recently had my bathroom renovated by this company and I couldn't be happier with the results. From start to finish, they were absolutely professional in every way. The quality of their work is truly perfect - they paid such close attention to detail and did an amazing job with everything. What's more, the price they quoted me was very reasonable and they stuck to it without any hidden costs or surprises. The whole process was smooth, efficient and stress-free. I would highly recommend them to anyone looking for building services - they really are top class and provide excellent value for money. Thank you for such a fantastic job! To Abdullah and his team.

Conversions - General- 19 Feb 2026
Hammer de silva provided a garage conversion quote and literally contacted every day saying he needed the job. After getting the job , I told him we need to go through building control to make sure everything is done in properly. There was about 2- 3 week delay because of building control . This guy keep taking multiple jobs and it’s more than one year and he’s still not finished with the job. He’s only done half of the job and keep coming up with excuses, he told us his wife being severely ill, his daughter being pregnant and needed help with delivery, other financial problems and endless excuses. In between he increased the price of job and took more money from us. He takes money spends it and doesn’t come back to work saying he doesn’t have money and need to find another job as well. Because of his careless work, I couldn’t use my utility room, decking area properly for over a year now costing so much stress and grief, might have to seek legal action if not finished in 2,3 weeks

We have contracted H&J Properties for our house refurbishment in London. I was impressed with the team's professionalism and project management from start to finish. We had no plans or planning approved, so we wanted a design and build company who will be able to look after the project from start to finish. They did just that. Working with the architects and the planning application before starting the project planning. As always, there are, of course, unforeseen issues arising with the old houses in london but I could't be happier with the communication received from the team. Thanks for the great job.
