Conversions - General- 30 Jan 2026
Harry did a great job installing a door between my hall and garage. His quote was thorough, comms were good and clear, and the price was reasonable. The install was awkward due to working near 4 supporting lintels but Harry took the necessary care to make sure it was done safely and properly, including everything being up to fire regs. The pictures look somewhat unfinished as I wanted to do the remaining decorating myself. Overall a top job. I highly recommend him and will be inviting him back for other jobs in the future.

Garage Conversion Specialist in Portsmouth
Hi I'm Dave. I took over my fathers business in 2008 which he had established in 1969. I immediately started working with him when i left school in 1992, so i have a great deal of experience and i learnt a great deal from my father who had a fantastic reputation around the local area. I take on any job big or small. I can do a bit of everything which means you won't have lots of different trades on site all at once.

Bathroom Fitting- 3 Sep 2018
Mike was very professional from the start of our process finding someone to build our en suite bathroom. He came up with the best solution for the long soil pipe we needed and demonstrated the previous experience to make it work. He even tried to fix our existing toilet when he had just come to quote! Mike and his colleague Kear worked hard through a very hot week in July and always left the house tidy each day. As long as you keep providing tea with 2 sugars they just keep going! They even fixed our garage door, probably out of frustration of opening it each morning. I would recommend Mike for any bathroom or plumbing work.

Conversions - General- 21 Feb 2021
Alan was very good, and did a professional job in sometimes difficult conditions. The only minor negative was that his communication could've been better. Sometimes I didn’t know when to expect him, when z simple phone call would have clarified the situation. I know the weather held him up sometimes, but even so, rather than me call him he should’ve been a big more proactive. So... would I use him again ...YES
