Why hire one general contractor for multiple trades?

Many projects cross trades: a kitchen remodel often includes new flooring and painting; an ADU needs concrete, roofing and windows. Keeping it under one contract means one schedule, one point of contact and one party accountable.

How we deliver your project

MDG Builders sells, designs and manages your project; the work is performed by licensed, insured subcontractors. You get one schedule, one point of contact and one written proposal, while each trade is handled by a licensed specialist, including C-39 licensed roofers for roofing.

Modern finishes without demolition

Ask about microcement, a seamless coating applied over existing tile, floors and counters, ideal for bathrooms, kitchens and floors. Compare it in our microcement vs. tile guide.
