Our Services

We offer comprehensive second story addition services in Oshkosh tailored to your home and goals.

Full Second Story Additions

A complete second story adds square footage to homes in neighborhoods like Sawyer Creek and Midtown. We manage foundation support, roof modifications, and all finishing details to blend the new level with your existing home.

Custom Room Additions

Add a bedroom, bathroom, home office, or recreation space. We design additions that fit your lot and match your home's character throughout Oshkosh.

Structural Framing & Support

Your home's structure must support new weight. We engineer and build proper framing, beam support, and reinforcement for safe, lasting results.

Electrical & Mechanical Rough-In

We coordinate electrical service upgrades, HVAC extensions, and plumbing installation. All systems are properly sized for new square footage and meet Oshkosh building codes.

Interior Demolition & Preparation

Selective interior work clears roof areas and opens walls for new framing. We minimize dust and disruption to the rest of your home.

Why It Matters

A well-executed addition increases home value, creates usable space, and avoids costly relocation. Smart planning protects your investment.

Structural Safety & Building Code Compliance

Improper framing or support leads to settling, wall cracks, and water damage. We follow Oshkosh building codes and engineer every detail for long-term durability.

Proper Coordination of Trades

Framing, electrical, plumbing, and HVAC must work together. Gaps in coordination mean rework and delays. We schedule inspections and manage the sequence.

Serving Oshkosh and Surrounding Areas

We work throughout Oshkosh and know the local building requirements, lot sizes, and architectural styles that define each neighborhood.

East-Side & Waterfront Homes

Homes near Menominee Park and River East often have older foundations and tight lot lines. We adapt framing and site logistics to fit these constraints.

Historic & Character Homes

Older homes in neighborhoods like Midtown require careful planning to match existing roof lines, siding, and window styles. We respect the home's character while adding modern functionality.

Modern Family Neighborhoods

Areas like Sawyer Creek and Oakwood have newer homes with contemporary designs. We create additions that flow seamlessly with current architecture and codes.

Frequently Asked Questions

Common questions about second story additions in Oshkosh.

Do I need permits for a second story addition in Oshkosh?

Yes. Any addition involving structural changes, electrical work, or square footage increases requires permits. We handle all permit applications and inspections.

Will an addition affect my property taxes?

Yes. An addition increases home value and living space, which may raise assessed value. Consult your assessor's office for specifics on your property.

How do you handle existing electrical and plumbing?

We assess current capacity, upgrade service if needed, and extend lines to the new space. Building code requires proper sizing for the added load.

What if my home has an older foundation?

We'll have a structural engineer evaluate load-bearing capacity. Additional support beams or reinforcement may be needed. Your foundation inspection is part of the assessment phase.

Can we live in the house during the addition?

Yes, in most cases. We contain work areas and manage dust. Some phases—like roof opening—may cause noise and temporary access disruption. We'll coordinate around your schedule.

How do I know the addition will match my home?

We evaluate your home's existing materials, roof pitch, siding, and trim. The addition blends siding, windows, and roofing to match. Detailed design sketches show the final appearance before we start.
