Marcel worked efficiently to deliver a high quality finish to our bathroom renovation. He communicated what he was doing at each stage of the renovation and was helpful in sourcing the materials. He worked long hours and always cleared up after himself. Marcel is friendly, honest and hardworking. The quote was very reasonable in comparison to other quotes we received, our first quote was honoured despite the job being more complex than initially anticipated. We will be using Marcel again for other jobs.

Absolutely fantastic service. We had cracks in our two main bedrooms, hallways and living room that needed repairing whilst we were living in the house with a baby and small child. Tilly got three men on the job to get it all completed asap. The team worked flat out without breaks and got done in 2.5 days (Tilly quoted aprox 3 days). They did over and above what I’d asked them to painting areas they hadn’t even replastered to make the hose look fresh. Tilly quoted & charged very reasonably too.
