Carpentry- 4 Aug 2018
Jason was very easy to communicate with before the job and turned up exactly when he said he would. The work was completed to a high standard, and on time, which was amazing given it can't be an easy job building a flat roof on the hottest days of the year. There were a couple of problems with the work, but they were resolved quickly and without complaint. I'd recommend Jason to others and would use him again on future projects.

Fencing- 13 Oct 2020
We had a new fence and part of the front garden concreted and the other part slabbed. Everything was done to a excellent standard and even when the weather was bad they still kept working hard. I would definitely recommend worx constructions as they where by far the best quote and they turned up on time every day and worked neatly and tidy. Thank you for the hard work.

Insulation- 14 Feb 2023
I placed an add in mybuilder.com to have my house fully insulated and received many replies including one from Sergiu. After meeting him I felt he was the best placed person to carry out the work as he was the most knowledgeable and seemed to know all about the various types of insulation and which one I needed for my home. He fully explained the procedure from start to finish was always on time and tidied up at the end of each day.His work is second to none and the price was very very competitive in fact much less then the big companies were asking.I am extremely happy with the job and the standard of finish. Sergiu is very police professional and trustworthy and I would have no hesitation in recommending him to anyone on here to carry out work in your home.
