Refurbish 60 sash windows throughout house in Walton

“I run a property management company and so I have dealt with a vast number of Refurbishments and renovations over many years. London Sash Works were extremely courteous, tidy and professional. The care they took over their work and ensuring everything was perfect before they left the job was second to none. I was extremely impressed and I have absolutely no hesitation in recommending them.”

Refurbish original window frames and fit new hardwood casement and sash windows

“We required a refurb of 2 upper floor Victorian windows including new sashes and fitment of new casement windows to replace those in the sitting room to the front. LSW quoted a competitive price following initial consultation which was well briefed, informative and highlighted potential issues to manage expectations around scope of work. The team on site was efficient, polite, conscientious and most importantly, highly skilled in their craft. Issues encountered were explained and dealt with promptly. LSW delivered an outstanding service with expert quality workmanship. Highly recommended.”

Removed secondary glazing and installed double glazed sash windows.

“Steve and his team did a fantastic job. They gave really helpful advice about the different options available, with a clear quote that was lower than the others we received. The work was all completed in the time they set out. When they started the work they found the frames were in worse condition than originally thought but they made sure to explain the situation to us and were clear about what extra work would be required and what it would cost. They called us and made sure we agreed to the extra work before they went ahead and the final invoice was exactly as agreed.”
