Plastering- 15 Apr 2024
We hired Dean for plastering and tiling our bathroom. Dean came out to review what was required and provided a break down quote quickly. His prices were fair and we appreciated that he was honest in what could and couldn't be done. Throughout the job he was clear on what times and days he could work and was always on time. He cleaned up after himself and never left a mess. The plastering work completed was done quickly and to a high standard, especially impressive when there was a large hole in the bathroom wall from the plaster blowing. We also hired Dean to complete the tiling of metro tiles for us, again the work was completed to a high standard and we are really pleased with the results. The wall (as with all Portsmouth houses) isn't level or straight! We trusted Dean to be left in the house alone and would definitely hire him again.

Extensions- 26 Jul 2024
Genuine person. He offered to carry out the job at a fair price. He always answered our calls, cleared his calendar for our side extension and started it on the day he told us. He is skilful but was honest if something was outside his expertise and asked us to hire the relevant person. Unfortunately, we encountered some difficulties, and the project could not be completed. would recommend working with Brendan

Bricklaying- 11 Oct 2015
Ray is a polite and respectful character who worked hard completing the work required. His timekeeping was very good, ensuring the work was completed on time. His estimate was accurate and honest. He actually popped back to finish some work - on his own time - to keep the project on track. Ray was also very flexible, and accommodated all my requests. I would recommend his services to others and will certainly use his skills for future projects.

Gerry and Jerry turned our ugly duckling of a house into a beautiful modern home, what more can I say!! They supported and mentored us every step of the way during the mammoth task of renovating a derelict house into our now superb family home. They succeeded in transforming the property into an absolute wow house for us and the family. We had everything refurbished from a perfectly fitted toilet fitted under the stairs, a newly fitted fabulous kitchen installed with every mod-con we required, new electrics and plumbing throughout, all the ceilings removed and replaced, damp eradicated from the property, a fantastic family bathroom fitted, and to top it all wonderful modern glass extension built with finesse which is now the heart of our home. The quotation was four A4 pages long which detailed every specification of the works line by line so we knew exactly what was being undertaken. We had regular clear communication and prompt timing throughout the project, and we are now currently being guided by them through the authority’s planning process to secure planning permission for a loft conversion. I would have no hesitation in thoroughly recommending Gerry and Jerry; they will be your project keepers helping turn your dream into reality.

Restoration & Refurbishment- 11 Sep 2022
My partner and I couldn't be more thrilled with the service and standard of workmanship that Matt and his team have achieved on our recent first floor conversion. The quality of the finish is fantastic and I would have no hesitation in recommending him to family and friends. Throughout the whole build communication was brilliant and at no point did Matt or Tony ever assume or make any decisions without consultation or checking in. Problems and solutions were worked through jointly and nothing was every to much trouble especially as the scope of what we originally asked for grew as the build went on. This was driven by us adding items to the original brief. They were really helpful with recommending showrooms and suppliers which made the decision making process streamlined. We were lucky to move out for the build but everyday our home was kept clean and tidy. Finally all snagging has been dealt with promptly and it's lovely to see that the company is also striving for a high standard of finish. Thanks very much for everything.
