"The new windows and glass roof are wonderful! They make an enormous difference to the house. The installers were efficient, polite, more than competent and cleaned up brilliantly after working incredibly hard each day. The products are excellent but the installers are what set the very high standards you achieve. I wouldn't hesitate to recommend Diamond and thank you for the enormously successful project"

"We chose Diamond because they are authorised installers for Bygone heritage style sash windows. Even though they are based in Poole, they were happy to take on this job on the Isle of Wight and the MD visited the property personally both before and on completion of the job. Two installation teams attended and were clean, efficient, purposeful and paid very close attention to detail and to getting things right. It was clear they took great pride in their work. From this experience we would unreservedly recommend Diamond when quality of product, service and workmanship is key" Bygone Sash Windows -
