Dormers and Additions

At Summit Remodeling, we work hard to make this kind of project less stressful for our homeowners during the construction process, and less expensive.

Expand Your Space Without Leaving the Home You Love

If your home is starting to feel cramped or no longer suits your family’s needs, you don’t need to move—you just need more room to live, work, and grow. At Summit Remodeling Inc., we specialize in building custom dormers and additions that enhance your home’s function, value, and comfort. Serving Nassau and Western Suffolk Counties, our team brings experience, creativity, and hands-on support to every project, no matter the size.

Why Add On?

Smart Space Solutions That Fit Your Lifestyle

A well-planned home addition is one of the most effective ways to increase square footage, improve flow, and personalize your home without the cost of buying new. Whether you’re welcoming a new family member, planning for multigenerational living, or working remotely more often, we can help you create the space you need.

Popular addition projects include:

Full and half dormers for Cape-style or colonial homes
Second-story additions to maximize your footprint without expanding outward
Rear and side extensions to create larger kitchens, living rooms, or bathrooms
Garage conversions for offices, guest suites, or recreation rooms
Master suite expansions for added luxury and convenience
ADA-compliant renovations to improve accessibility and aging-in-place design

If you’re unsure what’s possible, our architectural services help translate your vision into clear, buildable plans—often with permits and code compliance included in our pricing structure.

Transparent Process, Trusted Team

A Stress-Free Experience from Start to Finish

We know that home remodeling can feel overwhelming. That’s why Summit Remodeling focuses on open communication, efficient timelines, and minimizing disruption during construction. You’ll often see one or more of our owners on-site to ensure everything runs smoothly and to answer any questions along the way.

Our full-service approach means we take care of:

Structural design and layouts
Permit applications and code compliance
Framing, roofing, siding, and windows
Flooring installation, electrical, and plumbing
Interior and exterior finish work
Coordination with engineers or inspectors as needed

We also assist clients using financing options like 203k loans to fund major renovations or insurance settlements that require repair or restoration.

Materials That Last, Designs That Inspire

Blending New Construction with Existing Style

From roofing and siding to trim, paint, insulation, and lighting, our additions are crafted to match and enhance your home’s original style. We use only quality materials from trusted brands to ensure long-term performance and energy efficiency.

If your addition includes a new bathroom, kitchen expansion, or basement connection, our in-house design center can guide you through the finish selection process, so your new space feels cohesive and complete.
