Estimate the cost of your window project


Window glasses have a huge impact on the energy savings of a house. It is thus, a good idea to replace window glasses once in a while as a hygiene exercise. Many individuals have a tendency to wait until a window glass gets broken or becomes completely useless. However, this isn’t the best approach. This article will give you an idea about the costs involved in a normal window glass replacement project along with other related important information.

Is it cheaper to replace the glass or the whole window?

It is naturally a lot cheaper to replace just the glass instead of the entire window. As a matter, in fact, the total cost of replacing a window can be 50% more than that of just replacing the glass. So, which option should you go for? While the immediate money difference is a valid factor to consider, there are other things at play too. If you replace the entire window, you will be able to enjoy a significant boost in terms of outside noise cancellation, energy-saving, and resale value. This decision is more like choosing between a long term fix and a temporary solution.
