Why do you cost more?
Quality, and we refuse to do anything inexactly.
In construction, there’s EXACTLY and not exactly. You’ll hear others say we do things “right” (to them or you?) or “correctly” (I sure hope so!). But there’s no arguing exactly.
For example, air sealing and painting. You’re either exact or inexact. Being exact takes time, care and triple checking. If you’re not air-sealing exactly, then you’re leaching air, which technically isn’t “sealed”. (You’ve likely seen inexact painting so I won’t elaborate.)
What would you prefer for your home? Exactly or not exactly?
You get what you pay for in design and construction, and most often you get less.
