GeoBrix Inc is a fully licensed and insured contractor serving Mountainside and the rest of Union County. From roof replacements to full-gut remodels, we run the whole project under one contract — with local crews, real permits, and a written estimate before we start.

Working in Mountainside means knowing the local code office, the age and construction style of the housing stock, and the weather patterns that drive most of our calls.
Our estimators and crews live and work across Union County — we're not driving in from another state for the job. Every project gets a written scope, a project manager on speed dial, and a licensed & insured crew that treats Mountainside like the neighborhood it is.
