We wanted our new windows to reflect the integrity and appearance of our original Crittall windows. Over a period of 16 months, I was unable to find a company that could fulfil the criteria until I was told about DWL. From the first meeting, DWL was knowledgeable, experienced and patient. They went over and above expectations. Derek’s expertise is unsurpassed and invaluable. The product is of such a high quality and standard, as well as extremely aesthetically pleasing. They have achieved our aim of enhancing the look of our home. We would have no hesitation in recommending this company.
