You can tackle hanging Christmas lights yourself with the right tools, accessories, and a trusted friend or neighbor. You’ll need to purchase a ladder ($100 to $300), clips ($10 to $20), hooks ($10 to $15), and lights ($25 to $100 per string).

Otherwise, you should hire a trusted holiday light installer near you. You’ll pay an average price of $200 to $650, but you’ll have peace of mind knowing that the job is done correctly and safely.

In the Christmas days of yore, people braved winter weather to staple or tack their Christmas lights onto their rooftops or nearby surfaces like the fascia boards. Problems quickly emerged with that approach. Damage to the roof, even small marks from staples, provides entryways for moisture and similar issues that can hasten roof rot, wear, and associated leaks. Plus, some homes had tough fiber cement boards or other materials where staples and screws didn’t work.

It’s unnecessary to tip holiday decorators, and most professionals won’t expect it, but it’s a nice gesture to show your appreciation for their work. If the expert goes above and beyond to keep your delicate decorations safe, or they’re hanging your exterior lights and putting out lawn decorations in freezing temperatures or inclement weather, a tip between 10% and 20% of your total will be appreciated. Large jobs that include interior and exterior work are also good opportunities to tip, especially if your expert is performing a rush job close to the holidays.

Cold weather can cause older incandescent Christmas lights to fail by causing cracks in the finish or the glass itself. Modern LED lights are affected in the opposite way and perform even better as the temperature drops.
