Fall and Winter Landscape Lighting Maintenance Checklist
Quick Answer
To get your landscape lighting ready for fall and winter, turn off the power at the transformer, walk your property in daylight, and clear leaves and debris away from every fixture. Check for exposed or damaged wires, straighten any fixtures that have shifted, clean the lenses, and replace dim or burnt-out bulbs. Reset your timer when the clocks change in November, and mark fixtures near your driveway before the snow arrives. For anything electrical, like damaged wiring or a transformer that isn’t working, call a landscape lighting professional.
Fall sneaks up on us every year. One week you’re eating dinner on the patio, and the next it’s dark by six and the leaves are piling up in the garden beds.
This is the best time of year to give your landscape lighting a little attention. Once the snow starts, you’ll be busy clearing the driveway and booking your winter tire appointment. Your outdoor lights probably won’t make the to-do list. But an hour or two of care now can save you a repair bill in the spring.
Nite Time Décor has been designing, installing, and servicing landscape lighting in Oakville, Burlington, Mississauga, and the Hamilton area since 1998. Here’s the same checklist our technicians use, written so you can handle most of it yourself.
Why Fall Lighting Maintenance Matters
It protects your investment
Your lighting system adds curb appeal, makes your home safer, and lets you enjoy your yard after dark. Like anything that sits outside all year, it needs some care. Many of the problems we fix in the spring, such as crushed fixtures, corroded connections, and cut wires, could have been caught with a quick check in the fall.
It helps keep your family safe
By December, the sun sets before 5 p.m. in Oakville. That means you’re coming home, walking the dog, and taking out the garbage in the dark. Add ice and snow, and good pathway and step lighting becomes a real safety feature. A well-kept system lights up the places where people are most likely to slip or trip, and it helps create a more safe and secure home.
Ontario winters are tough on outdoor equipment
Our winters bring freeze-thaw cycles that can push fixtures out of the ground, road salt that can corrode metal near the driveway, and snowblowers and plows that don’t know where your pathway lights are. A little prep in the fall goes a long way. For more ideas, read our tips to protect your landscape lighting from the elements.
Before You Start: Turn Off the Power
Most home landscape lighting runs on a low-voltage system powered by a transformer, which usually plugs into an outdoor outlet. Turn the transformer off or unplug it before you clean, adjust, or touch anything. Low voltage is much safer than household current, but wet hands and wet ground are never a good mix with electricity.
Your Fall and Winter Landscape Lighting Checklist
Here’s the full list at a glance. We explain each step below.
Do a daytime walk-around
Clear leaves, mulch, and debris
Trim back plants and branches
Check for exposed or damaged wires
Straighten and re-aim fixtures
Clean lenses and fixture housings
Replace dim or burnt-out bulbs
Check the transformer
Reset your timer
Mark fixtures near driveways and walkways
Test the whole system after dark
1. Do a daytime walk-around
Pick a dry afternoon and walk your whole property. Look at every fixture, every visible stretch of wire, and the transformer. Bring your phone and snap a photo of anything that looks wrong. If you end up needing a service call, those photos help our technicians come prepared.
2. Clear leaves, mulch, and debris
Fallen leaves pile up against ground fixtures and trap moisture, which can lead to corrosion on the fixture and the wiring. Clear away leaves, mud, mulch, and anything the local critters have dragged in.
For higher fixtures, brush away cobwebs and old bird nests. If you find a wasp nest, be careful. It’s often safest to wait for a cold night when the wasps are inactive, or call a pest control company.
If you still have older halogen bulbs, this step matters even more. Halogens run hot, and dry leaves or mulch resting against them can be a fire risk. LED bulbs run much cooler.
3. Trim back plants and branches
Trees and shrubs can grow a lot in one season. Trim back any branches or leaves that block your lights or press against the fixtures. This lets each light do its job, and it gives you room to finish the rest of the checklist. Our pruning tips for landscape lighting explain what to trim and when.
4. Check for exposed or damaged wires
Over the summer, wiring can work its way to the surface from lawn aeration, garden edging, digging, or animals. Look for wires that are exposed, cut, or chewed.
Damaged wiring is a safety risk, especially if you have kids or pets, and winter weather will only make it worse. Please don’t just tape it up and hope for the best. Contact Nite Time Décor and one of our technicians will repair or replace the damaged wire.
5. Straighten and re-aim fixtures
Lawn mowers, foot traffic, and backyard games can knock fixtures out of place over the summer. Straighten any that are leaning and tighten the mounts where you can. Look closely for cracked housings or broken parts, since those may need replacement parts.
Then come back after dark to check the aim. A light that’s off by a few degrees can shine into someone’s eyes or light up your neighbour’s window instead of your maple tree. Good aiming also helps reduce light pollution.
6. Clean lenses and fixture housings
Dirty lenses can noticeably dim your lights. In most cases, warm soapy water and a soft cloth are all you need. Skip abrasive pads and harsh cleaners, since they can scratch the lens or damage the finish. Light scratches can sometimes be buffed out, but a lens that’s badly scratched or cloudy should be replaced.
If your lights aren’t as bright as they used to be, it may be time for new bulbs. This is also a great time to switch to LED if you haven’t already. Just make sure the new bulb is compatible with your fixture. Learn more about the benefits of LED outdoor lighting.
8. Check the transformer
With the power off, open the transformer cover and clear out any dirt, leaves, or insects. Make sure the wire connections on the terminal block are snug. Now’s also a good time to replace batteries in any timers or motion sensors.
If you notice scorch marks, a burning smell, buzzing, or an outlet that keeps tripping, stop there and call a professional.
9. Reset your timer
Daylight saving time ends on the first Sunday in November. If your system uses a manual timer, reset it so your lights come on when it actually gets dark. If you have a photocell or an astronomical timer, it will adjust on its own. Just make sure leaves or snow aren’t covering the photocell sensor. If your lights are controlled by an app, check the schedule there.
10. Mark fixtures near driveways and walkways
Before the first snowfall, place snow stakes or reflective markers next to fixtures along your driveway and paths. If you use a snow removal company, show them where your lights are. It’s one of the easiest ways to avoid a crushed fixture come March.
11. Test the whole system after dark
Turn the power back on and walk your yard at night. Is every light working? Is the brightness even? Flickering can mean a loose connection. If your system was installed by Nite Time Décor, check our warranty before paying for any repairs.
Adjust Your Lighting for the Winter Landscape
Your yard looks very different once the leaves come down. Lighting that looked great on summer foliage can look harsh on bare branches, unless you’re going for a haunted house look. A few simple changes can make your winter lighting look intentional.
Light the bare trees. Aim uplights at the trunk and branch structure of your deciduous trees. Their silhouettes can cast beautiful shadows on the walls of your home.
Shift the focus. Highlight evergreens, winter planters, and features like a fire pit that get overlooked in the summer. A cool white or soft blue light on an evergreen looks especially nice against the snow.
Turn off what you can’t see. Lights aimed at garden beds that are now dormant or buried in snow can be switched off or re-aimed for the season.
Think about where the snow goes. Snow hides the edges of paths and steps. Make sure your pathway lights clearly show people where to walk, even when everything is white.

Is It Time to Upgrade Your Landscape Lighting?
Outdoor fixtures get tired, just like anything else. If your system has been in place for years, fall is a great time to replace worn fixtures, fill in dark spots, and switch the rest of your bulbs to LED.
LED landscape lights use far less energy than halogen or incandescent bulbs, run much cooler, and last a lot longer. Many quality LED lamps are rated for tens of thousands of hours, which can mean well over a decade of normal use. They also perform very well in cold weather. Explore our residential landscape lighting services or commercial lighting services to see what an upgrade could look like.
A note on cast bronze fixtures
Cast bronze is strong, resists corrosion, and holds up well to cold, wet weather. Over time it develops a natural patina, anywhere from a deep brown to a greenish blue. Winter speeds that process up, so by spring your fixtures can look like they’ve always been part of the home.
If you’d rather keep the original finish, fall is the time to apply a protective coating. Some homeowners use a light coat of WD-40 or a clear matte sealant. Check with your fixture’s manufacturer first to see what they recommend.
When to Call a Professional [NEW]
Most of this checklist is easy to do yourself. Give us a call if you notice any of the following:
Exposed, cut, or chewed wires
A transformer that’s buzzing, scorched, or not turning on
A whole section of lights that won’t come on
Lights that still flicker after you’ve replaced the bulb

The best time is late October to early November, after most of the leaves have fallen but before the first snowfall. A second quick check in the spring will catch any damage from the winter.
No. Low-voltage LED landscape lighting is designed to run all year, and winter is when you need it most for safety. You can switch off individual lights that end up buried in snow or aimed at dormant garden beds.
Snow on its own rarely damages quality outdoor fixtures. The bigger risks are snowplows, snowblowers, shovels, ice buildup, and road salt. Marking your fixtures and keeping them clear of salty snow piles will prevent most winter damage.
Turn off the power first. Then wipe the lenses and housings with warm soapy water and a soft cloth. Avoid abrasive pads and harsh chemicals, and follow your manufacturer's care instructions.
The most common causes are a burnt-out bulb, a loose connection, a damaged wire, a tripped GFCI outlet, or a timer or photocell problem. Check the outlet and the bulb first. If that doesn't fix it, call a technician.
We recommend a quick DIY check each spring and fall, plus a professional inspection about once a year. Regular care helps your system last longer and catches small problems early.
Yes, for basic tasks like clearing debris, cleaning lenses, re-aiming fixtures, and changing bulbs with the power off. Leave wiring repairs and transformer problems to a professional.
Basic care like cleaning and clearing debris won't affect your warranty. If your system was installed by Nite Time Décor, check your warranty coverage before arranging any repairs.
