"I first started working with McNamara back in 1996 while working for Laing Homes Thames Valley, I was impressed then with their professionalism, organisation, reaction and response times and overall helpfulness. Forward to 2020 at I am still working with them at Linden Homes and am still impressed.

The interim years have seen me working with them with a variety of companies including The Berkeley Group and Shanly Homes, originally with Tom McNamara at the helm and now his son Brendan McNamara in charge.

As important as their excellent work has been their competitiveness in the market, this coupled with a ‘can do’ attitude leads me to confidently recommending them."
