We worked with Williams on our RIBA award winning project The Sekforde, a Grade II Listed Regency period pub. The brief was to re-point the brickwork to the listed façade, which had been badly affected from the removal of cement based render that had been applied sometime around the 1930s...

The Williams Restoration team took on the whole job, from removing the cement render through to re-decoration. There's no avoiding the fact that this type of work is messy and sometimes noisy, but they tried hard to minimise nuisance to ourselves and our neighbours. They did a good job, and the facade now looks very smart and authentic.
