Aside from a professional light installation company, there are a few other pros who may be able to help you hang Christmas lights. Along with specialty holiday decorators, a handyperson near you can also hang Christmas lights (and can fix that pesky drippy sink while they’re at it). Either way, not all of these pros will offer the service, so be sure to call ahead and get multiple quotes before you hire.

An affordable Christmas light bulb testing and replacement tool can make the job easier. But you can most likely make all necessary repairs yourself using common toolbox items if you’d rather avoid purchasing another gadget. 

You can take a few steps to prolong the life of your holiday lights. Make sure to replace burnt-out bulbs as quickly as possible to avoid overloading the rest of the circuit and knocking out more lights. Before packing them up each year, plug each strand into the wall to confirm everything is still working. Wrap the lights carefully back into their original packaging or something similar—winding a strand tightly together or leaving it to hang loose in a storage bin can lead to frayed or damaged wiring. 

Ensure you have a safe environment for them to work on, and there aren’t items such as logs, build-up of yard materials, missing or damaged shingles, and weak areas on the roof. Communicate any known electrical issues with contractors at the beginning of the project, and consider hiring an electrician to fix those. Finally, if you are attempting the project yourself, do so when there isn’t any rain, and you can safely get your footing on the roof using proper equipment, such as an extension ladder. Don’t attempt this alone, and have a helper nearby to assist.
