Know When To Call A Professional
While replacing a downspout is generally a manageable DIY project, there are situations where it’s best to leave the job to the experts. If your gutter system is sagging, your downspouts are improperly pitched, or you’re experiencing recurring water issues near your home, it could indicate a larger drainage problem.
