Mason Thomas Law – we are different.

"Buying a house has many elements that can be testing and often frustrating, but Mason Thomas Law managed the conveyancing process incredibly smoothly considering the complexities of our particular demands.

From the initial conversation Jo was supportive and very attentive to our needs. Face to face contact was easy to arrange in the office or at home, email communication was swift, no telephone call or message was left unanswered and communication even happened on the weekend at times! Not only was legal support offered, but also some wise advice when challenges arose from parties within the housing chain. The Covid 19 lockdown created an understandable issue however the support and guidance continued even though the housing market did not! We very much appreciate all of the hard work completing our transactions."

Mr and Mrs Gibb – Sheffield

"Having used Cathy in the past for the purchase and lease of business premises, the team at Mason Thomas Law acted on my behalf for my recent house move. Having moved numerous times in the past, I can honestly say that this was my least stressful move to date. A massive thank you to Cathy and Jo for a smooth and very professional service"
