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- 10 Dec 2017
Gary and Bryn have done a great job on our garage conversion and we are extremely pleased with the work they carried out. They ensured all structural work was completed to an excellent standard and they put in extra hours without complaint and free of charge where aspects of the job were more complex than anticipated. Each day they took care to tidy up after themselves. I received a number of quotes for this work and GB Refurbs’ was by far the most reasonable. All costs were transparent and fixed – there were no hidden extras as there can be with some builders. Aside from the quality of their work, Gary and Bryn are lovely guys and couldn’t do enough for me. While they were here they also carried out a couple of other odd jobs free of charge and without me even having to ask! I’m so impressed at the breadth of skills they have and will definitely use them for future jobs.
