Latest review:
Martin undertook a comprehensive renovation of my entire house, incorporating rear and side extensions, a loft conversion, and a rear pod addition. The project involved stripping the property back to its bare walls, reconfiguring room layouts, and installing entirely new bathrooms and kitchen facilities. Additionally, Martin oversaw the revitalisation of the garden area. Martin's professionalism and meticulous attention to detail were exemplary throughout the project. I am exceptionally pleased with the outcome of the work. This is not my first collaboration with Martin; I previously engaged his services for a complete house renovation in 2021.

Conversions - General- 17 Dec 2020
I signed the contract on 25th Nov for moving the walls of kitchen, bathroom, refitting bathroom and fixing kitchen and garden patio jobs. The contract was £10600. I paid £1800 deposit. They only ripped out kitchen bathroom’s walls at the same day for £2500. Then no works to be done in one week. A lot of arguments after I paid the deposit. He was always disagree me to buy the units. Didn’t allow me to have what I want to have. required add extra money all the time until I cannot afford. I told him my budget at the beginning. but he took me to a very expensive store for waiting a very expensive quote for 3 days. 2-3 times price over my budget. He was not agree me to buy from a normal stores/website. At the beginning he told me £6000 for the bathroom including units, £4500 for labour. Finally he required me to increase the budget to £12000+. I asked a lot of times he never told me the date, timescale until I cannot wait any more. The deadline is 18th Dec. However, he didn’t start yet. He didn’t want to refund me the deposit. He finished the downstairs heating fitting and bathroom rewiring in one day, then told me it cost £1800 deposit. It is an outsourcing company. All the staffs were from other companies and working as part time job. The director was born in 1993. The company is one year. Now I cannot move in before Christmas. Everything needs restart next year. And I have to pay extra one more month rent. I didn’t get deposit back, wasted one month,very bad mood for few weeks.

Conversions - General- 24 Jul 2025
Wesley and team did a fair job, however we felt like corners were cut or jobs were not completed to a high standard. During the build we had issues that arose such as a leak in the wall from plumbing and we had asked for an extra for a radiator to be replaced upstairs- the guy that was used for this was miserable and also caused a leak in the heating system. Also when levelling the floor this was done over several days and ended up being very un-level which he did have to come back and correct. We had doors installed which are sub par at best- avoid using his carpenter! The worst part of the situation was our French doors which were “new” however installed terribly- not level and gritty to open. At first when called back, Wesley seemed to want to help to solve the situation, but after 4 months of chasing he came to take a broken part of the door away to be replaced and has now gone silent. So now looking at having to pay more money to solve the problems from the build.
