    Avoid at all costs! Works not carried out according to work schedule Gave multiple excuses for why work not done as agreed Blamed me for "changing things" even though everything discussed and agreed Added surprise costs cos he'd misquoted and mishandled funds already given Took our money (over 50% of initial quote) and didn't do the work Demanded more money and when I refused, he left the project unfinished very shoddy workmanship.

    Alex and his team were fantastic from start to finish. They arrive when they say they will do and they clean up after they have finished each day. We wouldn't hesitate to use his services again in the future.

  • Underpinning a garage and taking out wooden garage floor and putting in a concrete floor

    Alex and his team were able to start the job with very short notice given. Fixed price and schedule of payments agreed. Work completed to a high standard and they actually resolved a couple of other issues while there. Would use again and would recommend to others.

  • Replace lintel, repointing and replacing defective brickwork

    A tidy, friendly team who carried out the work in a manner which inspired confidence in the company. They tided up after they had completed every day. The only hiccup wasn't due to them but was caused by a third party sub contractor letting them down, they recovered well. Gave a believable timeframe for the works needed.

  • Quotation provided for Insurance work

    Alex came out on time, to one of my commercial properties, that required extensive replacement work to suspended ceilings on 3 floors. He was professional and knowledeable. The quote provided was extremely comprehensive . As I had to provide the insurance company with 2 quotes, unfortunately, on this occasion, JAT Developments was not chosen. However, I would have absolutely no issues with using this company for any future work.
