A well-built deck extends your living space, increases your home's enjoyment, and adds lasting value to your property. Ireland Contracting has been building custom decks for Pittsburgh-area homeowners since 1994 — from straightforward treated-wood platforms to multi-level composite designs with built-in seating and railing systems.

We work with homeowners through the full process: design, material selection, permitting, construction, and final inspection. Whether you prefer the warmth of natural pressure-treated lumber or the low-maintenance durability of composite decking, our experienced crew brings craftsmanship to every post, beam, and board.

Our Process

  1. Design consultation to discuss layout, size, materials, and features

  2. Site assessment including slope, soil conditions, and footing requirements

  3. Permit application with drawings and structural details as required by your municipality

  4. Footing excavation and concrete placement below frost line

  5. Framing, decking, and railing installation followed by final inspection

Composite decking has become the dominant choice for homeowners who want a beautiful deck without the annual sealing, staining, or painting that wood requires. Products from leading composite manufacturers are available in dozens of colors and board profiles that closely mimic natural wood grain, and they resist moisture, splintering, fading, and staining far better than pressure-treated lumber. For homeowners who prefer the look and feel of natural wood and are willing to maintain it, high-quality pressure-treated lumber remains a solid and cost-effective option.

Every deck we build starts with proper footings. Pittsburgh's winters push frost several inches into the ground, and footings that do not extend below the frost line will heave and settle over time, causing structural problems and code violations. Ireland Contracting digs and pours footings to the depth required by local code — a detail that separates a properly built deck from one that needs repair within a few years.

Our team handles the full permit process, which for decks typically includes structural drawings and inspections at footing and framing stages. We manage that process entirely — you should not have to navigate building departments or coordinate inspection scheduling on your own. When the final inspection passes, we do a walkthrough with you to confirm every detail meets your expectations. Building decks has been part of our business for more than three decades, and we take as much pride in a beautifully finished deck as we do in a perfectly installed roof.

Decks — Frequently Asked Questions

How long does it take to build a new deck?

Build time depends on deck size, design complexity, and weather. A straightforward single-level deck might be framed and decked within a week once permits are in hand. Multi-level or custom designs take longer. We give you a realistic schedule during the design phase.

What warranty covers a new deck?

Composite decking products typically carry 25-year to limited lifetime warranties against fading, staining, and structural failure. Pressure-treated lumber is warranted by the lumber producer against rot and insect damage. Ireland Contracting's workmanship is covered by our installation guarantee.

Can I finance a deck project?

Yes. Financing is available for qualifying deck projects. Because decks often represent a significant investment, spreading the cost over time makes sense for many homeowners. Ask about current financing programs when we visit for your design consultation.

Will I need a permit to build a deck?

Most municipalities in the Pittsburgh area require a building permit for new decks and significant deck replacements. Ireland Contracting handles permit applications, structural drawings, and all required inspections as part of the project.

What areas do you serve for deck construction?

We build decks throughout the Pittsburgh metropolitan area, including most of Allegheny County and surrounding communities in Butler, Washington, and Westmoreland counties. Call 412-492-7663 to discuss your project.
