Doing home improvement projects makes it less likely that you’ll have to pay for expensive repairs down the road. When you replace your roof and gutters, for example, you protect your home from water damage. Some projects add more value to your home than others. Some home improvement projects are expensive but add little value to your property. Comparing the cost of the project to its value can help you determine your asking price when it’s time to sell.
