Permanent Christmas lights cost about $18 to $40 per linear foot installed by a pro, which puts most whole-house jobs at $2,500 to $6,000. DIY kits run roughly $3 to $5.30 per foot. Your final price depends on roofline footage, roof height, number of controllers and local labor rates.
Permanent Christmas lights cost per foot: pro vs DIY
Pricing is based on linear feet of roofline, not square footage of the house. Here are the ranges published by installers and manufacturers. Treat them as ballparks, because quotes vary by region and system.
| Option | Cost per linear foot | Typical 150 ft job |
|---|---|---|
| Professional install (Trimlight, Jellyfish-style systems) | about $18–$40 | about $2,700–$6,000 |
| DIY smart kit, basic tier | about $3 | about $450 |
| DIY smart kit, flagship tier | about $5.30 | about $800 |
Installer sites tend to quote $18–$35 per foot for standard jobs, with complex rooflines and multiple zones at the top of the range. One Jellyfish figure puts the average full system near $4,600, and many homeowners land between $3,000 and $6,000. Those numbers come from sellers, so get at least two local quotes before you trust any average.
Worked example: a 150-foot house
Say you have a one-story ranch with 150 feet of eave and gable edge you want lit.
- Pro install at $20–$35 per foot: $3,000 to $5,250.
- DIY at $2.99–$5.30 per foot: about $450 to $800 in lights, plus any tools and extras.
- Difference: roughly $2,500 to $4,500, which is what you pay for design, mounting, warranty service and not climbing a ladder.
To measure, run a tape or a string along every edge you want lit: eaves, gable rakes, peaks and any dormers. Add 10% for corners, drops to outlets and mistakes. If you measure only the front of the house, you will underbuy or get a low quote that grows later.
What makes the price go up or down
Five things move the total more than brand does:
- Roofline length. Every extra foot adds cost, so a long ranch can cost as much as a compact two-story.
- Complexity. Many gables, dormers, turrets and tight peaks mean more cutting, mounting and labor time.
- Height. Second-story edges need taller ladders, lifts or extra crew time. Some installers charge more for steep roofs.
- Zones and controllers. Each controller or power supply handles a limited run length. Long houses need more of them, and separate zones let you light the front and garage independently.
- Region. Labor rates in large metro areas run higher than in smaller markets.
Pixel-addressable systems that can show different colors on each bulb cost more than white-only strips. If you only want warm white and a few holiday colors, a simpler system can save money.
Extra costs people forget
Quotes and kit prices often leave out the items that show up later:
- Outdoor outlet. If there is no weatherproof, GFCI-protected outlet near the roofline, adding one typically means an electrician. Cost depends on your panel and wiring, so get a local quote.
- Extra power supplies. Long runs often need injection points or extra supplies, not just one box.
- Mounting hardware. Clips, adhesive, connectors and sealant for outdoor joints.
- Lift rental or second-story labor. Often the reason a two-story quote is higher.
- Permits and HOA approval. Some areas require a permit if you add a hardwired circuit, and some HOAs restrict permanent lighting. Check before you buy.
- Repairs. Ask what the warranty covers if a section or pixel fails, and who pays for the visit.
Can you install permanent Christmas lights yourself?
Yes, on a single-story house with an existing outdoor outlet, DIY is realistic. Most kits come with channels or track that you screw or clip to the fascia, then snap the lights in. Plan a full weekend for 150 feet, and test the lights on the ground before mounting them.
Our Govee permanent outdoor lights review covers one popular DIY system in more detail. If you only want traditional seasonal strands rather than a fixed system, a connectable set such as the OZS 400 LED warm white lights costs far less.
Safety rules for DIY:
- Use only outdoor-rated, UL or ETL listed products, and keep every connection sealed against water.
- Plug into a GFCI-protected outlet. Have a licensed electrician add any new outlet or hardwired circuit, following local code (NEC).
- Stay within the controller’s maximum wattage and run length. Do not daisy-chain past the limit.
- Falls are the main danger. Use a stable ladder on level ground with a spotter, and hire a pro for second-story edges or steep roofs.
Running cost, lifespan and warranty
LED systems are cheap to run. Wattage per foot varies by model and brightness, so check the spec sheet. As an example only, assume 1.5 watts per foot at full brightness on 150 feet, which is 225 watts.
- Holiday use: 225 W for 6 hours a night over 30 nights is about 40 kWh, or roughly $7 at 17 cents per kWh.
- Year-round accent use: 5 hours every night at full brightness is about 410 kWh, or roughly $70 a year. Real use is usually lower, because colors and dimmed scenes draw less than full white.
Manufacturers often rate LEDs for tens of thousands of hours, which can mean a decade or more of normal use, but that is a rating and not a guarantee. Warranties differ by brand and installer. Ask for the term in writing, whether it covers parts and labor, and whether it transfers if you sell the house.
Are permanent Christmas lights worth it?
They pay off when you would otherwise hire someone to hang and take down lights every year, or when you will use the lights for more than Christmas. Seasonal hanging commonly runs a few hundred dollars a year, often $300 to $800, but get local quotes because it varies with house size.
| Scenario | Upfront cost | Seasonal hanging avoided per year | Rough break-even |
|---|---|---|---|
| Pro system | $3,000 | $800 | about 4 years |
| Pro system | $4,500 | $500 | about 9 years |
| DIY kit | $600 | $400 | about 1.5 years |
These figures ignore electricity and repairs, which are small by comparison. The practical rule is that if you plan to stay in the house 8 to 10 years and would pay for hanging each year, a pro system can make sense. If you hang lights yourself for free, DIY permanent lights are mostly a convenience and not a savings.

Frequently Asked Questions
How long do permanent Christmas lights last?
Many LED systems are rated for tens of thousands of hours, which can equal 10 to 20 years of typical use, but ratings are not guarantees. Actual life depends on weather, sealed connections and brand. Check the written warranty term before buying.
Do I need an electrician to install permanent Christmas lights?
Not if you already have a working GFCI-protected outdoor outlet within reach. If you need a new outlet or a hardwired circuit, hire a licensed electrician, because local code and permits may apply.
Do permanent lights add to my electric bill much?
Usually not. LED systems on a typical house often cost a few dollars during the holiday season, and roughly tens of dollars a year if you run them nightly. Check your model’s wattage per foot and your local rate for an exact figure.
Can permanent Christmas lights stay up in winter weather?
Quality outdoor-rated systems are built for rain, snow and temperature swings, but ratings differ. Check the product’s weatherproof rating and operating temperature range, and make sure all connectors are sealed.
