Holiday Light Removal and Storage: Protecting Next Year's Set

The short answer: first dry day above 40 degrees, after January 1

Pick the first dry day above 40 degrees after January 1 and get it done. The reason is the wire, not the calendar. Holiday light cord is PVC-jacketed, and PVC stiffens sharply below about 25 degrees. Flexing a cold string cracks the jacket where the wire enters each socket, and that crack stays invisible until the run fails next December. Boise's January normals are a 38 degree high and a 25 degree low, so most weeks hand you a two or three hour midday window. Take it. Waiting until March buys ten more weeks of UV, wind fatigue, and freeze-thaw on the clips for no benefit at all. Here is the number that reframes the whole subject: six hours a night for 100 nights is 600 run hours a season, against a 25,000 hour LED rating. Your lights are rated for something like 40 seasons. They do not burn out. They get broken and they get cooked.

Getting them off the house without paying for it in April

Pull each clip straight off the shingle edge or gutter lip. Do not walk the ladder down the eave dragging the string sideways, because that scrapes granules off the shingle edge and levers sockets loose one at a time. If a run is frozen into gutter ice, leave it alone. A jug of warm water frees it in a minute, while yanking it breaks conductor strands inside a jacket that still looks perfect. Never chip ice out of a gutter with a tool. If the original install used a staple gun, count the staples out and back, because every one you leave behind is a hole in a fascia board or a shingle. Then retrieve every clip. Plastic clips left up year-round go brittle in one or two Idaho summers at 2,700 feet of elevation, snap in a spring windstorm, and end up jammed in a downspout elbow. We pull them out of downspouts every April.

Dry them, test them, and tag them before anything goes in a box

Nothing you do in storage matters if the strings go in wet. Snowmelt sitting in a socket for ten months turns the contacts green, and green contacts are a dead run. Spread everything out in a garage or basement for 24 to 48 hours before it touches a tote. While they dry, plug in every single run. Finding a dead string in January costs you nothing. Finding it on December 1 costs you an evening and full retail. Tag the dead ones with painter's tape and a note, and do not put them back in the box to look at later, because you will not. Buy the replacements between December 26 and mid-January, when holiday stock runs 50 to 75 percent off. Match the brand and the stated color temperature. Warm white at 2700K sitting next to warm white at 3500K is obvious from the street, and there is no fixing it once it is on the roof.

The attic kills more light strings than the weather ever will

Most sets are spec'd for storage between roughly minus 4 and 140 degrees. An unvented Idaho attic runs 40 to 60 degrees above outside air, so a 98 degree Boise afternoon puts your boxes at 140 to 155, and Boise averages around 19 days at or above 95 every summer. You are baking them. Heat is what destroys the rectifier in the plug and the epoxy on the lamps, and that is the real cause of the flickering half-string people blame on a bad bulb. Store them in an unheated garage instead. A garage swinging from 20 degrees to 100 sits well inside spec, because cold is not the problem here. An interior closet or a dry crawlspace works too. Use hard totes with latching lids, not cardboard and not bags, because mice chew PVC jacket and nest in cardboard light boxes. Put the totes on a shelf, off the concrete floor.

Coil flat and label by roofline, not by guesswork

Strings almost always fail at the socket junction, where the wire enters the lamp base. Coiling tight around your hand or elbow puts a hard bend right at that junction, dozens of times per string. Wind flat instead. Cut a 12 by 14 inch rectangle out of a box, notch both ends, and wind the run onto it, or spend $12 on a reel, or lay a loose figure eight into the tote. Then label by roofline section and footage: front gable, 46 feet, C9 warm white. Take one photo of the lit house from the street before you start and one of each open tote, and next November's install drops from a full day to an afternoon. Bag the clips per run and tape the bag to its coil. A 150 foot roofline eats 150 to 250 clips at 20 to 40 cents each, so what you drop in the grass is $40 to $90.

When to skip the service, and what cannot be saved

Here is where we talk you out of spending money. If your lights sit on single story eaves you can reach from a 6 foot step ladder on dry, level ground, take them down yourself and keep the $150 to $400 a takedown quote runs in this valley. Hire the work out when height, roof pitch, or ice is the reason, not convenience. Second, some strings cannot be saved. Green corrosion in the sockets, a cracked jacket, or flicker that appeared after a summer in the attic is not a repair job, and a $6 fuse does not fix a cooked rectifier. Replace the run. Third, and this one costs us real work: if your gutters were cleaned in November and your lot has no mature trees, do not book a January gutter cleaning just because someone is already on a ladder. There is nothing in them yet. Wait for the late-spring cottonwood drop.
