OVERVIEW
Why Homeowners Choose Lorenzi Deck Company
For nearly 50 years, Lorenzi Deck Company has helped homeowners transform their outdoor living spaces with custom deck design, new deck construction, and professional deck resurfacing.

Every project begins with a personal consultation to understand how you use your outdoor space before recommending the best layout, materials, and construction approach.
OUR SERVICES
Three Ways We Help Homeowners
Deck Design & Consulting
Custom layouts, material recommendations, and architectural integration tailored to your home and how you’ll use the space.
Deck Construction
New builds, tear-downs and rebuilds, and code-compliant construction engineered for Western PA weather.
Deck Resurfacing
A cost-effective refresh when your frame is sound — new boards, railings, and stairs without a full rebuild.
Custom Deck Design & Consulting
Your deck isn’t just an outdoor platform — it’s a place for family gatherings, relaxation, entertaining, and extending your living space into the outdoors. Our deck design and consulting services deliver:
- Custom-designed decks that fit your home’s style and property layout
- Multi-level deck design with integrated stairs, railings, and seating
- Premium composite and wood material options for any aesthetic and budget
- Structures engineered to withstand Western Pennsylvania weather
- Careful attention to local building codes, safety, and structural integrity
Whether you want a simple single-level deck, a multi-level entertainment space, or a low-maintenance composite deck, we deliver results that stand the test of time.
Expert Deck Construction Services
Every successful project starts with detailed planning. Our deck construction services include:
- Personalized consultation to explore your vision and goals
- Design concepts that enhance both function and curb appeal
- Material recommendations based on durability, maintenance, and style
- Architectural integration that complements your home’s exterior
We work closely with you to make sure your deck maximizes space and fits your lifestyle — whether that’s a cozy family deck or a full outdoor entertainment area.
Deck Resurfacing & Renovation
If your existing deck frame is still structurally sound but shows signs of wear, our deck resurfacing services are an excellent alternative to full replacement. Resurfacing lets you:
- Replace old deck boards, railings, and stairs
- Bring your deck up to current building code
- Give your outdoor space a refreshed, like-new appearance
- Save on labor costs compared to a full teardown and rebuild
This solution is ideal for homeowners who want a fresh, durable deck surface without the expense of a complete replacement.
DECISION GUIDE
Should You Replace or Resurface Your Deck?
One of the most common questions we hear. During your consultation, we inspect the structural framing, support posts, footings, joists, railings, stairs, and building-code compliance — then tell you honestly which path makes sense.
âś… Resurfacing May Be Right If:
- The structural framing is still sound
- Support posts and footings pass inspection
- You want a like-new look at a lower cost
🔨 Rebuilding Is the Safer Bet If:
- Framing, joists, or posts show structural issues
- The deck doesn’t meet current building code
- You want to change the layout or footprint
Nearly 50 Years of Experience: What We’ve Learned
Every property is different. Some homes sit on steep hillsides that require specialized footings. Others have aging deck frames that can safely be resurfaced instead of replaced. We’ve also seen homeowners buy inexpensive composite materials that faded prematurely or were installed incorrectly. Nearly 50 years of hands-on experience lets us catch these issues before construction begins.
Across thousands of completed projects, we’ve watched building codes evolve, decking systems shift from traditional wood to engineered composites, and Pittsburgh’s terrain, drainage patterns, and freeze-thaw cycles teach us something new on almost every job. That depth of experience with older homes and Western Pennsylvania conditions shapes every recommendation we make.

MATERIALS
Choosing the Right Composite Decking
Not all composite decking is the same. Here’s how the three brands we install compare:
TimberTech
Realistic wood grain with excellent durability and minimal upkeep.
Trex
A great balance of value, low maintenance, and long-term performance.
AZEK
Premium PVC with exceptional resistance to moisture, fading, and staining.
Not sure which material fits your home? Our design consultation walks through the tradeoffs so you choose with confidence.

What types of decks do you build?
We specialize in custom composite deck design and construction using premium brands like TimberTech, Trex, and AZEK, known for durability, low maintenance, and long-lasting beauty.
Do you offer free deck consultations?
Yes. We provide personalized consultations to discuss your vision, space, material options, and layout so we can design the right composite deck for your home.
Why choose composite decking over wood?
Composite decking from TimberTech, Trex, and AZEK offers superior durability, resistance to moisture and fading, and requires significantly less maintenance than traditional wood decks.
Is deck resurfacing worth it?
When the underlying frame is still structurally sound, resurfacing gives you a like-new deck at a fraction of the cost of a full rebuild. We’ll tell you honestly if your frame qualifies.
Does a new deck increase home value?
A well-built deck adds usable living space and curb appeal, and composite decks in particular tend to hold their value well thanks to their durability and low maintenance needs.
Which deck material handles Pittsburgh weather best?
Composite and PVC decking from TimberTech, Trex, and AZEK stand up best to Western Pennsylvania’s freeze-thaw cycles, humidity, and seasonal moisture — with far less warping or rot than traditional wood.
How long does construction take?
Timelines depend on deck size and complexity, but most composite deck installations move efficiently once materials and permits are secured.
Do you handle permits?
Yes. We manage all required permits and make sure your deck meets local building codes and safety regulations throughout the South Hills.
