Driveways (Paved & Loose)- 10 Jan 2026
Hired for a large raised sandstone patio and tarmac driveway at around £10k. Set up and job were fairly problematic. Few difficulties in damage and surface protection but agreeable solutions were offered. Tarmac drive was done without issues. Sadly one patio edge stone came loose in weeks and they did not return to fix. Several months later another large edge stone has fallen off and several others are loose (likely stone not slurry primed or mortar bed dried too quick. Have request follow up to review and rectify but still waiting on a reply...

We had the pleasure of working with Alfa Style Limited on our loft conversion and we can recommend them highly and without reservation. Their work is incredible, attention to detail outstanding – our build was done with care and precision. They turned up on time every day, worked incredibly hard and quickly. In addition, they were extremely clean and tidy in the workplace – they never left the worksite in disarray. This is the first time we have done such a big project – Ruslan, Slava and their team were amazing. They were brilliant at explaining what was going to happen, day by day, week by week and translated the more technical information! No question or query was too much. The service after the build had finished has also been great, calls to check everything is OK and any queries we have, they are only a phone call away. We have had so many compliments from family and friends who have seen the finished build … it has made a huge difference to our house, we could not be happier.

Bricklaying- 25 Mar 2018
I instructed the level of the walls and gable to be built up to. The brickwork was covered in hessian and I paid him after he said that it was all done. After he departed, I looked under the hessian and the gable was not built up to apex. One area was not built up where it needed only a couple of courses and the other bricked up wall was left lower than I had stated. I phoned Nick and he sent his brother to finish the job next day. The 2 sides of the gable are still at different angles and the brick work is still lower than I had asked for on the other walls. This was not a big job. Only needed a few courses of brick work to level off as the building has been derelict for a few years. My view was that no one will risk a negative review and that is why I paid him. Unfortunately I was let down at a critical moment as the pitch roof chippy was following the bricklayer on this job. Very sad as he could have been engaged on other brickwork on this building.
