They took the time to assess every tree and shrub and highlight the highs and lows to create depth and texture in my yard. The value of my home has definitely increased thanks to WA Outdoor Lighting 👍🏻

 Trustindex verifies that the original source of the review is Google. This is the second time I’ve used these folks, the first project being very small, and second being rather large. In both cases WA Outdoor Lighting accomplished a great look, in a timely, professional and friendly way. They were always available for any questions and, on the second project which uses a an app to operate, were more than happy to walk me through the app twice, as I aimed to learn it. Would be my first call for any other projects.

 Trustindex verifies that the original source of the review is Google. I've had exterior lights, installed by Washington Outdoor Lighting, for about 4 years now.  Installation was done well and professionally and they still work great.
There was one light that failed last year and they came out and replaced it, as well as adjusting positions of other lights that had been moved a bit over time with landscape services.  They did charge a fee for that, but it wasn't very much.
Overall I would recommend Washington Outdoor Lighting.  If I were to add to my set up they would be the first to call.

 Trustindex verifies that the original source of the review is Google. We appreciate the competent service and quality lighting from Kyle and his entire team at WAOL. We had an old, funky system, and the new landscape lighting was well designed, and then installed as designed, in good time, cheerfully, carefully, at a competitive price -- and we love the result. This is a fine family-owned company.
