Plumb and Square is a small web studio for HVAC, plumbing, electrical, roofing and exterior companies. Plumb is true vertical. Square is a true right angle. It's how the trades check their work, and how we check ours.
Trades companies win on word of mouth, fair prices and showing up on time. Their websites rarely show it. When we checked 26 trades websites in November 2026, half had something visibly broken, like a dead button or a phone link that doesn't dial, and fewer than one in five let a customer book online.
So we build one thing: clean, fast websites that make the phone ring and the calendar fill. Flat prices you can see before we talk. A site you own outright. Care that runs month to month, so we keep earning the work.
We'll show you what's working, what's broken, and what a new one would look like.
