Garden Works

Once again, Karl and Alex have completed another garden project for us. They have worked so hard and the weather was against them but nothing was too much and they have gone above and beyond. We cant wait for the warm weather when we can enjoy the garden. Already planning the next project! We cannot recommend Karl and Alex enough. Thank You

Excellent job.

Just had Karl and Alex to alter my kitchen and put up a stud wall. Excellent quality work and kept me up to date with everything. Good cleaning service afterwards.
Would highly recommend Karl.
Thank you.

Kitchen wall removed

Excellent service, kept me up-to-date on when building materials and skip was being delivered.
Arrived time he stated and got straight on doing the job.
Left the space he was working in tidy and cleaned up outside before leaving.

Would highly recommend, would definitely be getting Karl back for when we’re ready for our extension/future work

Thankyou again Karl 👍🏼

Excellent service

I needed some crumbling bricks replacing. Karl came round to give me a quote at the agreed date and time. As it was a small job we agreed he could fit the work in around other jobs. He kept in touch throughout and once we fixed a date he once again arrived on time. The bricks matched the existing wall and he did a first class job in replacing them for a very fair price. I have no hesitation in recommending Karl for such jobs.
