Whilst it’s impossible to give definitive figures or likelihoods, there are a few factors that go into whether your home’s value will be improved with whatever home improvement work you have done on it.  One fairly big factor is functionality. For example, if you replace every single pane window in your house with our double-glazed, superior framed A++ grade replacement windows, you will effectively grant your house a range of benefits. One of these is energy efficiency since 25%+ of heat is lost through single-pane windows. With A++ grade double glazing, however, you prevent around 75%+ of the heat you’d otherwise lose.  Another is aesthetic. Nice-looking additions to your home often result in not only better value added to the property for resale, but also likely more interest in the property in general.  That being said, how much value you get differs. Some people believe that you get 100% of what you pay for in the overall value, but the truth is that it’s usually a fraction. Overall, when it comes to high-quality Bi-Fold Door installations, there are actually a lot of reports of high levels of return on the investment – over 60-80% on average.
