  • In most cases we can fit slim double glazing units to your existing sash or casement windows, however this is subject to a survey, for suitability Please contact us to arrange a site visit.

  • If you have chosen a package that includes painting then yes we would repaint the windows after the repairs have been completed

  • If you have your own preferred decorator then by all means you can use them to carry out the painting on your windows, you can discuss this with us at the survey stage.

  • This is a very common problem, as part of our draught proofing installation or refurbishment packages we will free up your windows and return them to full working order.

  • This will all depend on a number of factors that we have to consider such as location, window size and accessibility, the amount of repairs required, if there are any broken glass panes, if you require draught proofing installation, or double glazing upgrades, painting etc.

    It is best to speak to one of our advisers and book a survey.

  • Yes. Usually this can be resolved. Our draught proofing service will eliminate that problem.

  • We regularly work on Grade 2 listed buildings & properties in conservation areas. Like for like repairs do not require planning permission as they do not change the appearance of the building.

  • No, our slim double glazing units are designed to look like single glazing but have the modern day attributes.

  • No, we do all of our work onsite, however, if we need to have a new sash or casement window manufactured because its beyond economical repair we will remove it and cover the window opening with board to make the property secure during the manufacturing process.

Your windows are the eye’s to the world, & we can make them shine again.
