Origin of the Name

In construction, a plumb line is used to test the straightness of a wall. If the wall is warped or off angle, the wall is not secure and will be easily toppled.

Isaiah 28:17 says that “righteousness will be the plumb line”, meaning that God will test His people to make sure their conduct is upright.

At Plumb Line Design, we believe both images should embody what we do. Our work should result in quality lighting installations that stand the test of time and be performed with integrity and honesty.

On Time, Every Time Guarantee

At Plumb Line Design, we appreciate that meeting deadlines is critical to project success. That’s why we offer our “On Time, Every Time” guarantee. If we miss a deadline, then we will take a 10% reduction in fee.

If the deadline for our deliverable is noon and it arrives at 12:01, we consider that late and will reduce our fee by 10%. While some may see that as extreme, we view maintaining the trust of our clients and following through on our commitments as non-negotiables.

Core Values

At Plumb Line Design, our Core Values drive what we do and how we do it.

Unwavering Attention to Detail

The smallest details can have the biggest impact. Nowhere is that truer than how the subtleties of light can influence the human experience.

Exceptionally Proactive

Being proactive leads to production, while being reactive leads to reduction. We strive to be value-adding team members by initiating concepts, conversations, and coordination.

Micro to Macro

A quality lighting design considers the perspective from multiple scales and vantage points. The tree and the forest must both be kept in mind.
