    Andy and his team came when they said they would and removed a wall to open up our kitchen. They were clean and tidy throughout. They completed the job to a very high finish. Andy helped me source other trade people to do work on my house. To be honest, every work person associated with Andy was exceptional including the Plumber, Plasterer and carpenter. Would happily invite Andy and his team back for any further work.

  • Garden transformation

    Location: HP2

    Excellent work! They did a brilliant job on my garden. Cleared the overgrown weeds, cleaned the patio, laid paving, installed artificial grass and painted all my woodwork. They turned up on time every day, worked through the hottest June day and delivered on time and on budget. They were very clear on what everything would cost and offered very helpful suggestions on what could be done with the garden. Absolutely no hesitation is recommending them.

  • Loft Room

    Location: WD18

    I wanted somewhere to store my clothes but didn’t want a full loft conversion. I spoke with Andy about what I wanted and we came up with a plan. He was particularly helpful giving ideas on the finished look far beyond what I thought could be possible. The work was carried out to a high standard. I was very very happy with the outcome. I would definitely recommend A&T and have used them on lots of other projects since.

  • Loft Conversion

    Location: WD18

    From Day 1 Andy and his team were thoroughly professional. Turning up on time sticking to the schedule. We remained living in our house whilst the project was going on and the team did an excellent job of keeping the place tidy and being considerate of having a family underfoot. This was a complex build and with any complex build problems arose that Andy was quick to rectify showing a fine aptitude for problem solving and project management. Andy treated the build as if it was his own home, always checking that I was happy with the progress and consulting me on teh finer details.
