TREX COMPOSITE DECKING
Trex Deck Builder in Pittsburgh, PA
For nearly 50 years, Lorenzi Deck Company has helped homeowners throughout Pittsburgh’s South Hills create outdoor spaces built around their homes, their properties and the way they actually want to use them. Every project is personally overseen by Vince Lorenzi, from the first consultation through construction.
Custom Trex Decks Built for Pittsburgh Homes
We design and build custom Trex composite decks for homeowners throughout McMurray, Peters Township, Upper St. Clair, Bethel Park, Mt. Lebanon and the surrounding Pittsburgh communities. Whether you’re replacing an aging wood deck, resurfacing an existing structure or starting with a brand-new design, we’ll help you decide whether Trex is the right material for your project.
Why Homeowners Choose Trex
Pittsburgh decks deal with rain, snow, humidity, summer sun and constant seasonal swings. Trex’s protective shell is designed to resist fading, staining, scratching and mold, and it skips the routine staining and sealing that wood decking requires. It’s a strong fit if you want:
- Lower-maintenance decking
- Resistance to rot and splintering
- A variety of colors and wood-grain looks
- Coordinating railing and outdoor-living components
- An alternative to pressure-treated wood
Trex’s current limited residential warranties range from 25 to 50 years depending on the collection — always worth reviewing for the specific product you choose.
Trex vs. Wood Decking
Trex makes sense if you want lower routine maintenance, resistance to rot and splintering, a consistent appearance and long-term manufacturer warranty coverage.
Wood typically costs less up front and gives you the look of real wood, but needs more ongoing maintenance, including staining or sealing.
The right choice depends on your property, budget and what you want from the deck long-term — we’ll walk through it together during your consultation.
Which Trex Collection Is Right for Your Home?
Budget, sun exposure, desired appearance and how you’ll use the space all factor in. We’ll help you narrow it down during your consultation — here’s a quick overview of Trex’s core lines.
Trex Enhance
A great starting point for homeowners who want composite performance while keeping material costs in mind.
25-Year Limited Warranty
Trex Select
A step up in performance and appearance options for homeowners who want more from their decking.
35-Year Limited Warranty
Trex Transcend
Trex’s premium line, with the widest range of appearance and performance options.
50-Year Limited Warranty
Warranty terms vary by collection and should be confirmed for your selected product. You don’t have to decide before meeting with us — we’ll talk through design, budget and color during your consultation.
New Trex Deck Construction
Building a deck is about more than picking a board color. A well-designed deck needs to work with your house, yard, elevation and entry points. We design and build custom composite decks for Western Pennsylvania properties, including homes with sloped yards and challenging terrain, and we handle required permits for every project. Depending on your project, we help plan:
- Deck size, layout and traffic flow
- Stairs, landings and railing
- Grill, dining and seating areas
- Multi-level and elevated layouts
- Decking colors and borders
Trex Deck Resurfacing
An older deck doesn’t automatically need to be torn down. If you like your existing size and layout, resurfacing with Trex composite decking may be an option — but what matters most is what’s underneath. We evaluate the framing, joists, beams, posts and footings before recommending resurfacing versus a full rebuild.
Have an older deck you’re unsure about? Let Vince take a look before assuming you need to rebuild the entire thing.
Built for Pittsburgh’s Hills and Terrain
The South Hills includes homes with significant elevation changes and uneven terrain — design challenges that aren’t always obvious until you’ve worked on local properties. We regularly design around:
- Steep backyards
- Elevated first floors
- Walkout basements
- Drainage and grading
- Existing concrete or patios
- Long stair runs
- Multi-level outdoor spaces
- Deck-to-yard access
- Existing deck structures
Does Trex Decking Get Hot?
Yes — like most outdoor surfaces, Trex decking can get hot in direct summer sun. Darker colors generally feel hotter, so if your deck gets strong afternoon sun, it’s worth considering a lighter color or one of Trex’s heat-mitigating products. We’ll factor this into your color selection during your consultation.
Nearly 50 Years of Deck-Building Experience
Materials have changed considerably since Lorenzi Deck Company got started. What hasn’t changed is the importance of designing the structure correctly. For nearly five decades, Vince Lorenzi has personally overseen every deck the company has designed, built and resurfaced throughout Pittsburgh’s South Hills — working with premium decking from Trex, TimberTech and AZEK.
That experience is what determines whether an old deck can be resurfaced, how a deck should work with a sloped property, where the stairs should go, and which material actually fits how you’ll use the space.

Trex Deck FAQs
How long does Trex decking last?
Trex’s current residential limited warranties range from 25 to 50 years depending on the collection — Enhance carries 25 years, Select 35 years, and Transcend up to 50 years. Actual product life also depends on installation, use and care, so it’s worth reviewing the warranty for your specific product.
Does Trex decking need to be stained?
No. Trex’s composite decking doesn’t require the routine staining that wood decking does. Trex recommends periodic cleaning, with specific care depending on the product and conditions.
Can you put Trex decking over an existing deck?
Possibly — but the underlying structure needs to be evaluated first. We inspect the existing framing and structural components before deciding whether resurfacing or rebuilding is the right approach.
Is Trex good for Pittsburgh weather?
Yes. Composite decking eliminates several maintenance concerns tied to exposed wood, which makes it a strong option for Western Pennsylvania’s moisture and freeze-thaw conditions.
Does Trex get hot in the summer?
It can, especially in direct sun. Darker colors generally feel hotter, so color selection matters for decks with heavy sun exposure — we’ll factor that into your consultation.
Does Lorenzi Deck Company handle permits?
Yes. We handle required permits and build every deck to applicable local building-code and safety requirements.
Start Planning Your Trex Deck
