How does home additions work?
Home Additions follows 4 clear steps, from site evaluation and design to a final walkthrough. A vetted, licensed pro manages the schedule, keeps the site clean, and does not consider the job done until you are satisfied.
Site evaluation and design
We assess your foundation, roofline, and utility runs, then work with a licensed architect to produce permitted drawings.
Structural and foundation work
Footings, foundation extensions, or beam work are completed and inspected before framing begins.
Framing and envelope
Walls, roof structure, windows, and exterior cladding are installed to match your home's existing profile.
Interior finish
Insulation, drywall, flooring, and trim complete the addition so it's seamless with the rest of your home.
A home addition is the most ambitious (and most rewarding) project you can take on without selling your house. Whether you need a master suite, a sunroom, or a full second story, our team manages architecture, permits, and construction under one roof.
We treat additions as a craft, not just a construction job. Every addition is designed to be indistinguishable from the original structure: matching materials, matching rooflines, and fully integrated mechanical systems.
Planning related work? Homeowners who book home additions often pair it with roofing or siding installation. Every Pro House Maintenance project starts with one free, fixed-price estimate covering the full scope.

Home Additions questions, answered.
How long does a home addition take?
Most room additions take two to four months from permit approval, with timeline driven by foundation work, framing, roofing, and interior finish sequencing. Second-story additions or projects with significant square footage run four to six months. We build a phase-by-phase schedule into your contract with milestone dates so expectations are clear and trackable from day one.
Will the addition match my existing home?
Yes. We source matching siding, roofing, trim profiles, and window styles so the addition reads as original to the house rather than bolted on. Our architects review the exterior elevations and roofline integration before framing begins. Interior transitions (flooring, ceiling height, trim details) are also designed to flow seamlessly between the existing structure and the new space.
