I engaged Dworks to supply and fit three new double glazed hardwood sash windows for my Victorian mid terrace property. These windows replaced old single glazed timber sash windows. I enjoyed dealing with this company from start to finish. They were very quick at responding to e-mails and visited my property to measure up and quote. Installation was done by competent tradesmen who made a minimum of mess and cleared up afterwards. The windows seem to be solid and of good quality. FENSA certificates were provided plus an insurance backed guarantee. The work was done at the agreed price. I'm very happy with the finished result and would certainly use this company again.
