If you’ve had an accident late at night, we won’t be able to replace your glass immediately. In this case, we will board up your window with plywood boards to maintain security, and arrange for the glass to be fitted once it is available. We operate a 24-hour rapid-response Harpenden boarding-up service, to give you peace of mind when you need it most. We can also board-up large Harpenden commercial premises when the owner has vacated the building, or is in the process of a large-scale refurbishment, where the building needs to be protected against squatters and other intruders. All boarding-up jobs in Harpenden and the local area include a free quote on replacement glass if required.

Double Glazed Units
In the trade we say a double glazed sealed unit has broken down. This means that the perimeter edge seal has lost its integrity and that it is letting in moisture somewhere. The moisture is hard to spot at first, sometimes becoming only visible as the sun or another heat source draws the moisture up by evaporation.
Typically the moisture will be drawn in as the atmospheric pressure changes and it will build up, eventually condensing into water inside the sealed unit. This can sometimes look like a fish tank with several inches of water that cannot escape. Whether the seal has failed or the glass is broken, we will replace and re-seal all types of Double Glazed Units.
