I had a commercial property converted into 2 one bedroom flats. Akam builders did an A-class job. The work was done to a very high standard and within the time scale stated by Gurwinder. I was impressed by the extra work he did without any extra charge. This builder is a genuine and reliable builder. The work is in perfect condition after 6 months.
