Built to Last: Outdoor Construction Done With Precision and Care

Quality deck and porch construction requires far more than surface-level carpentry. Proper foundations, structural integrity, weather resistance, code compliance, and refined finishing details all demand experience and technical knowledge. Since 2008, Andrew Viohl has designed and built exceptional outdoor living spaces throughout New Castle County, Delaware County, and Chester County.

 

As a Wilmington native, Andrew understands local building requirements, regional weather patterns, and the expectations of homeowners who value long-term durability. Every project is approached with careful planning and a commitment to craftsmanship that ensures your investment performs beautifully for years to come.

Custom Deck Construction Designed Around Your Lifestyle

Composite and PVC Deck Installation for Low-Maintenance Durability

Modern composite and PVC decking systems offer outstanding durability with minimal upkeep. These materials resist fading, staining, moisture damage, rot, and insects while maintaining their appearance season after season. We install premium composite decking in a range of colors, grain patterns, and finishes that complement both traditional and contemporary homes.

 

Our installation process includes reinforced framing, hidden fastening systems for a clean surface appearance, coordinated railing systems, and integrated lighting options. The result is a deck that combines the look of natural wood with the performance advantages of advanced materials.

Traditional Wood Deck Construction With Timeless Appeal

For homeowners who prefer the authentic character of natural wood, we build custom decks using pressure-treated lumber, cedar, or tropical hardwoods. Each option offers distinct visual appeal and performance characteristics, and we guide you in selecting the right material based on your budget, maintenance preferences, and design goals.

 

Our wood deck construction emphasizes proper footings, structural framing that exceeds code requirements, thoughtful board layout, and attention to drainage and ventilation. We focus on craftsmanship at every stage to ensure your wood deck remains strong, stable, and visually striking.

Multi-Level Deck Designs That Maximize Outdoor Space

Homes with sloped properties or homeowners seeking defined outdoor zones often benefit from multi-level deck designs. These structures create separate areas for dining, lounging, grilling, or enjoying a hot tub while working naturally with your property’s terrain.

 

Constructing multi-level decks requires advanced structural planning and strict code compliance for stairs and guardrails. We manage every detail while delivering a layout that enhances architectural interest and improves how you use your outdoor space.

Custom Railings, Built-Ins, and Architectural Features

Railings provide safety while shaping the overall style of your deck. We install traditional wood balusters, composite systems, cable rail designs, decorative metal, and glass panels that preserve views without sacrificing protection.

 

Beyond railings, we incorporate features that personalize your space. Built-in seating, integrated planters, pergolas for shade, custom lighting systems, and defined gathering areas can all be incorporated to elevate both form and function. Each element is thoughtfully integrated into the overall design.

Deck Stairs and Accessibility Solutions

Safe and properly constructed stairs are essential to any elevated deck. We design stairs with appropriate rise and run dimensions, secure handrails, durable tread materials, and seamless transitions to surrounding landscaping.

 

For homeowners with accessibility needs, we incorporate wider stairs, gradual transitions, and railing configurations that make entry and exit more comfortable for everyone.

Custom Porch Construction That Extends Your Living Space

Screened Porch Construction for Comfort and Versatility

Screened porches provide protection from insects while allowing fresh air, natural light, and outdoor views. We build custom screened porches that become favorite gathering spaces throughout spring, summer, and fall.

 

Our construction includes solid foundations, properly framed roofing systems, waterproof integration with your home, high-quality screen systems, ceiling fans, lighting, and detailed trim work. Whether connected to a kitchen, family room, or positioned to capture backyard views, a screened porch can significantly expand your functional living space. Designs can also allow for future conversion into a three-season room if desired.

Covered Front Porch Construction That Enhances Curb Appeal

A covered front porch adds architectural presence and creates a welcoming entry. We design porches that complement your home’s style, from traditional columns and railings to clean-lined modern profiles.

 

Construction includes proper footings, structural supports, roofing integration, durable decking materials, and carefully selected ceiling treatments and lighting. Every detail is considered to ensure the porch feels original to your home rather than an afterthought.

Open Porch and Elevated Deck Porches

Open porches offer flexible outdoor space for furniture, grilling, and relaxation. We build elevated porch decks with appropriate railings, stairs, and optional roofing to create comfortable outdoor rooms that feel connected to your interior living areas. These spaces work with kitchens, living rooms, and primary suites.

Porch Additions, Enclosures, and Conversions

Transforming an existing deck into a screened porch, enclosing an open porch, or adding a new porch structure requires careful structural evaluation and integration with your home’s architecture. We assess foundation requirements, roof tie-ins, and design continuity to ensure additions look cohesive and structurally sound.

Expand Your Home’s Value and Everyday Enjoyment

Well-designed decks and porches enhance your experience of your home. They create space for entertaining, quiet relaxation, outdoor dining, and everyday moments in fresh air. In communities such as Greenville, Christiana, Haverford, Newtown Square, and Chadds Ford, high-quality outdoor living spaces meaningfully contribute to property value and market appeal.
