This is a question we are asked regularly and is really hard to put an exact cost on. The price of a heritage window can vary due to factors like the size, style, number of windows, and the level of restoration required. It’s also worth bearing in mind that the cost of fitting or specialist pointing and sealing works will be added to this. Some very old windows are also difficult to remove or repair, which would increase these costs considerably, as well as extra charges for reinforcements.
