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.

Extensions- 17 Jan 2018
A Total disappointment Ricky agreed to install a porch and roofing. He advised us to install new pvc doors agreeing to fit the roof after. This started mid November with a promise to be completed before Christmas. On his instruction we paid other workers to complete the preparation works and then the morning of the Job he sent a text message advising that he will no longer be able to attend the job. Thankfully we were able to find a local reputable roofer -plasterer-tiler who completed the work to a very high standard I feel very let down as I had put total trust in his promise to complete the work. Unfortunately based on this I cannot confidently recommend Ricky to a friend family, or anyone else.

Loft Conversion- 14 Oct 2021
Zilvinas produced drawings promptly and at a very competitive rate. He attended several site visits and ensured to incorporate all of our ideas. We have received fantastic after sales service from GoldBerg Engineering throughout the project and would not have had the results we have, without Zilvinas. Goldberg Engineering has provided brilliant guidance throughout, through rapid response emailing, regular Skype and several site visits. Goldberg approved each work phase and continues to offer support. Thank you very much! Highly recommend, 5Star!
