Year one costs the most because year one includes the lights — commercial-grade product cut to your actual rooflines. After that, professional Christmas light installation is a service fee on materials you already own, which is why the pricing question is really a two-year question.
What drives the number
Linear footage of roofline is the base: more edge, more light, more labour. Height and pitch multiply it — second-storey peaks take ladder time that single-storey eaves do not. Trees, columns, and wrapped elements each add their own labour, and design complexity does the rest.
A simple single-storey roofline outline and a two-storey with peaks, wrapped trees and walkway lighting are different projects, which is why real quotes follow a property walk rather than a phone guess.
Why year one includes materials
Professional installs use commercial-grade lighting cut to your measurements — not boxed strings in fixed lengths. You are buying a fitted product: better brightness, better weather tolerance, no daisy-chained plugs, custom fit to the architecture.
Those materials are yours afterwards. Stored, labelled and reused, they amortise over years of seasons — which is what makes year two and onward meaningfully cheaper.
What the service fee buys after that
Install, in-season repairs, removal in January and storage until next November. No ladder, no tangled tote, no dead section staying dark until you find the bulb.
When comparing quotes, ask what happens when a section fails in week two — in-season maintenance included versus a call-out fee is the difference that matters most and gets asked least.
A design walk gets you a real number for your actual house. Booking now means an autumn walk and an early-November install. Read more about professional Christmas light installation →
