Our base rate is $795 + tax. The final price depends on your project’s complexity and specific elements. A few factors can influence the cost, including the number of rooflines, a steep roof, multiple trees or shrubs, wreaths or garlands, and a boom lift when needed. As a general guideline, the average budget typically ranges from $1,250 to $1,500. Since every project is unique, we offer a customized design and a quote tailored to your property.
Yes, absolutely! We can arrange a multi-year contract for Christmas light installation. We offer attractive discounts for multi-year contracts: a 10% annual discount for a 2-year contract, and a 15% annual discount for a 3-year contract. It is an excellent way to plan your installations, enjoy a turnkey service year after year, and benefit from preferential pricing.
We exclusively install our own LED lights. This approach allows us to guarantee the quality of our products and the reliability of our service, while ensuring a professional and long-lasting installation.
As soon as possible! We begin installations in November. However, since the weather in Québec can be unpredictable from year to year—with cold, rain, snow, and freeze-thaw cycles—November quickly becomes a very busy month. It is also the time of the year when many homeowners want to wrap up their final pre-winter tasks: gutter and window washing, preparing the home’s exterior, and so on. To enjoy your decorations as long as possible before Christmas, we recommend booking as early as August or September. That way, you can be among the first clients to enjoy your Christmas lights and avoid last-minute delays. Don’t wait until the first snowfall to make your reservation! Book early and fully enjoy the magic of the holiday season.
You do not need to buy the lights. We supply and install our own decorations and LED lights, so we guarantee a high-quality result and professional service.
Yes, absolutely! Each installation is unique and customized to your tastes and your home style. You can choose from several light colors: warm white, pure white, blue, orange, red, or green. During the consultation and design phase, we will use software to let you visualize different options and select the concept that best suits you. Warm white remains homeowners’ most popular choice, thanks to its elegant and inviting look. However, we can also create a Christmas-themed design, for example, by alternating white, green, and red for a more festive and traditional look.
If a light stops working after installation, don’t worry! Our turnkey service includes maintenance of your decorations, including replacing any faulty bulbs right up until Christmas. If a problem arises, our team responds quickly to keep your decorations looking flawless and shining brightly throughout the holiday season.
No, you won’t have to worry! We install an automatic timer with your decorations so the lights turn on and off at the scheduled time each day. There is nothing to plug in or unplug—sit back and enjoy the festive atmosphere!
Once the holiday is over, you don’t have to do a thing! We remove all decorations in January, unless a special agreement was made before installation or snow conditions temporarily prevent us from removing them. After removal, your decorations are stored until the next season, so they’ll be ready to be reinstalled the following year.
To preserve your included service warranty, contact us as soon as you notice a problem. If a repair is necessary, our team will be happy to take care of it for you.
Yes, absolutely! We understand that your preferences may evolve once the decorations are in place. Although major changes may be more complicated after installation, we can, whenever possible, make adjustments or add certain elements to accommodate your expectations. Just let us know your needs, and we will evaluate the requested changes. Additional fees may apply depending on the nature and scope of the changes.
