Tina P4.5 / 5 · 16 Feb 2026

We engaged 4&J construction in renovating one of our bedrooms – removing carpet and a really old fitted wardrobe, then making good the wall behind. Plus we also had them extend the skirting board and coving, and fit a picture rail ready for redecoration. They did this work to an excellent standard, and kept me well informed throughout the whole process. The work uncovered some exposed pipes from an old boiler, so they also put me in touch with a plumber who could remove them so we could fit flooring. They left the room clean, tidy and ready for redecoration as requested. Would recommend.

4&J constructions Ltd ( Sergio & Team ) did a fantastic job in renovating my bedroom space. From demolishing the old storage space, laminating the flooring ( removing old carpet) ,supply and fitting the skirting boards and painting the walls , cieling as preferred by us was all professionally done. The house was kept completely clean before work and post work as well. Would highly recommend them for any building work to be carried out.
