What Homeowners Say About Us

Raz and Vali are very nice people. Quick and responsive. They helped me remove four large chimney breasts, replace the boiler and radiators, and renovate the whole bathroom, plus some other jobs in the house. They work very hard every day and barely had any break. Very efficient and Vali can complete a lot of jobs in one day. Very impressive. Highly recommended.

Raz and team installed 4 steel beams as part of a kitchen/diner extension. Raz was informative and helpful throughout the process and his team worked long hours to get the job done. We ran into some issues with the delivery of the steel which seemed to be the steel suppliers fault but it did cause some unnecessary stresses and delays on the job. It would have been smoother having the steel ordered and onsite well before installing however all was resolved in the end and we're happy with the job.

Raj was excellent. He did the the job within the timeframe and within the quote. His team is very dedicated and hard working. They worked every from 8am in the morning and finished around 6. They didn't leave until we were happy with the job. I would highly recommend Raj and his team.

Fitting of a mew bathroom suite including tiling- Raz and his team showed a genuine interest in the job and had no problem with any scope creep. Good comms and suggestions throughout works. A good finish and immediate response to snagging issues. Many thanks and will use again. Recommended.

Converting the front yard into a gravel driveway. It was done at time and I was satisfied at the beginning. However, when I started driving, the gravels spread away at the edges and apparently that's because of the sloping nature of my area and I have to sort that out. Updated (2 weeks later), it seems now to be more settled as I was told, and it doesn't bother me any more. Thanks!
