Is there anything you need to do on the day of the repair?
If possible clearing the area around the workspace will help, remove any curtains/blinds, ornaments, plants etc as this will save any accidental damage. Our staff will bring dust sheets and place where needed, we will also tidy up and remove any broken glazing, window parts, etc which we then recycle through a licensed waste company – and not dump at the side of the road.

Do I pay upfront?
Once all work is completed we will ask for payment – cash, cheque or visa, etc if you haven’t already received an invoice our staff will have been given one to pass on to yourselves so you can check you only pay the price we quoted. We suggest you keep the invoice safe as this is part of your guarantee.

Can you upgrade my current windows?
When simply replacing a DGU (double/triple glazed unit) we would recommend considering a modern energy efficient unit,  TWG manufacture and fit A-rated warm edge spacer bars as standard to our double glazed units with no extra cost to the homeowner. These new spacer bars replace the aluminium bars which cause heat transfer through the glass, choose True Window and Glass for your window repair and you could benefit from a DGU that can save money on heating at no extra cost.
