As David Crook pointed out in the Wall Street Journal this week, remodeling your home isn’t always a great investment. Many projects won’t pay for themselves in terms of increasing the value of your home—they’ll cost you money in the long run. But he does go on to suggest that being smart about remodeling can mitigate this. By focusing on energy-efficiency, either in its own right or as part of a larger project, you can cut your home’s energy costs signicantly and actually make the project pay for itself. Investing in your home makes sense—if you do it wisely.
