Kitchen Remodeling
From a same-layout refresh to a full reconfiguration with a new island, we design, permit and build kitchens that work as hard as you do.
Bathroom Remodeling
Walk-in showers, tub-to-shower conversions and full primary-bath renovations, built watertight and finished with care.
ADU Construction
Garage conversions and detached accessory dwelling units, managed from feasibility and plans through permits, utilities and move-in.
Roofing
Roof repairs and full replacements in composition shingle, concrete tile and clay tile, performed by C-39 licensed roofing subcontractors and managed by our team.
Fencing
Wood, horizontal slat and vinyl fences and gates that add privacy and curb appeal, set on solid posts.
Flooring
Hardwood, engineered wood, luxury vinyl plank and tile, installed flat, tight and ready for daily life.
Room Additions
Ground-floor additions that add a bedroom, suite or family room, engineered, permitted and tied seamlessly into your home.
Concrete
Patios, slabs, walkways and driveways poured on properly prepared bases, for a finish that lasts.
Windows
Energy-efficient window and sliding-door replacement that brings in light and keeps out heat and noise.
Painting
Interior and exterior painting with careful prep, clean lines and durable finishes.
Decks
Wood and composite decks and outdoor living spaces built on sound framing and footings.
Microcement
Seamless, modern microcement for floors, walls, showers and counters, applied over existing surfaces with no demolition.
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.
