Restoration & Refurbishment- 8 May 2012
We hired Audrius initially as his quote was very competitive and I felt confident with his knowledge and practical approach to repair our roof, this was to remove all the slate tiles, lay new felt, new batons and replace with as many usable original tiles, this was organised and completed with as little disruption as possible to ourselves and we were highly pleased with the finished roof. We discussed further renovation works we wished Audrius to carry out so work continued with loft conversion, basement conversion, chimney brests removed, new boundary wall, replastered ceilings throughout, his team were polite and always cleared away when they left for the evening and they were always early in the morning. All problems were sorted quickly and the best solutions found always with costs kept to a minimum, we also changed things here and there and Audrius always had excellent ideas which would save costs and keep our budget in check. Audrius and his team are professionals and we have other work for them in the future and will not be using anyone else.

I found mr. Mark to be a very professional guy. Arrived promptly the next day, had a look at what was required to be done and gave me a quote. The work was done a few days later, as agreed, professionally, done clean cuts within the wall and added a lintle too. It finalised with the pointing over the bricks in the lintle area and left the place spotless once the job was finished. He even reduced, on his own accord, money from the original quote, as the job was done faster than he has anticipated. I will definitely employ him for future works and recommend him whenever i got the chance! Thank you again for your work Mark!

Sall and his team did an impressive job taking down the wall for us. Everything was excellent from first contact, to punctuality and quality of the job itself. They completed it in less time than expected and left the place tidy and without a mess. Harry came the day before to make sure that it's not a load-bearing wall and that everything will go as per the plan. I can't recommend Sall and his team enough for their great work.
