Your most common questions about home additions—answered clearly and professionally.
What types of home additions do you offer?
We specialize in room additions, second-floor additions, kitchen extensions, master suites, sunrooms, all-season rooms, and garage conversions.
How do I know if my home is suitable for an addition?
We evaluate your structure, property lines, zoning rules, and foundation to ensure your home can safely support the addition you want.
Do I need permits for a home addition?
Yes. Most additions require permits and city inspections. We handle everything for you from start to finish.
How long does a home addition take?
Most additions take 8–16 weeks depending on size and complexity. We provide a clear timeline before starting construction.
Can I live in my home during construction?
Yes—most of the time. We take steps to minimize disruption, protect your home, and maintain safe access.
How much does a home addition cost?
Costs depend on the size, design, and materials. After an on-site visit, we provide a transparent, detailed proposal tailored to your project.
Will the new addition match my current home?
Yes. We carefully match materials, rooflines, siding, trims, windows, and finishes so everything blends seamlessly.
Do you help with design and layout?
Absolutely. We offer full architectural planning, layout recommendations, and guidance on maximizing space and natural light.
What is the process to get started?
We begin with a consultation, site visit, and measurements—then move on to design, permits, construction, and the final walkthrough.
Will an addition increase my home's value?
Yes. Additions typically boost property value by increasing livable square footage, enhancing curb appeal, and improving functionality.
Do you offer warranties?

We help you explore options based on your goals, budget, and home layout so you can make the best choice.

Yes. We guide you through selecting flooring, cabinetry, paint colors, lighting, and more so everything flows beautifully.
Can you work within my budget?
We offer options and design adjustments to fit your budget without compromising quality or safety.

Reviews from Our Clients
P
Henry came out and replaced a rotted sill plate in my home and I could not have been
more happy with the work; a true professional. He came same day for an estimate and
started the next day. Sent progress pics and left the area cleaner than he found it.
I would definitely recommend.
