Fitting went very smoothly, and so quickly. We're very pleased with the windows. Renderers are following hot on your heals! Mark and Simon were a superb – skilled, knowledgeable, amiable, efficient, unflappable...the ideal people to represent DD on site. Great job. Our experience of DD has been very positive – great product, highly professional people, and a company with real integrity. So many companies make bold claims about customer service only to disappoint. We found DD's service far exceeded our expectations.

Generally an excellent robust product, well made and installed. I would be happy to recommend Dempsey Dyer for further work with Elliott Group.

Contracts Manager

Elliott Group (Hospital Refurbishment)


At pre order stage we had many specification changes and found the estimating department helpful to accommodate our needs. A sample window was delivered to site for our clients approval prior to the order being placed. Supply went smoothly with any variation orders dealt with promptly and efficiently. Invoices were correct. All in all a good service. I would not hesitate to use Dempsey Dyer in the future.

William Davis (New Build Social Housing)


The Gelder Group "discovered" Dempsey Dyer earlier this year, and having now dealt with them on various projects, both at tender stage and also contracts which have been completed on site, have found this contractor to be competitive, helpful, knowledgeable of their product, well organised on site and able to provide a totally acceptable installation. This attitude has also been noticed and favourably commented upon by our clients. We would have no hesitation of recommending Dempsey Dyer for any PVCU window installations.
