We Don’t Just Replace It.
We Prove It’s Done Right.
Any company can swap a unit. Grandmark diagnoses on video, installs with a licensed roofing crew, and delivers completion proof before you sign. No guesswork. No callbacks. No surprises.
You receive pre- and post-install video showing every seal, penetration, and connection — before you pay a dollar.
We’re licensed roofers. Every roof opening is professionally flashed and sealed. Most HVAC companies caulk and walk.
Digital gauges and micro-cameras before any number is given. You pay for what’s actually wrong — not what’s easiest to sell.
