I would like to say that this work was completed perfectly. They were always on time and cleaned up after themselves. The plumber was there all day and never stopped. We found them all very approachable and helpful. No pressure sales. Would gladly have them back for another job and would recommend them to others.

Extensions- 2 Nov 2018
Building a 2 storey rear extension and hired Jamal to do the Block work. Initial ground storey heavy Hollow block walls for the 3 x 3m extension completed in only 3.5 days by Jamal himself with no extra help. Hardworking young guy. I was nearly bedbound with sciatica and in great pain and he immediately offered to source and buy on my behalf extra blocks required to relieve further stress on me. Very helpful, reasonable and understanding. Explained anything I asked him diligently. Knows his job and I will be calling him back when I have the money to complete the block work for the 2nd storey.

What experience do you have with similar extensions in Wandsworth?
