Deck Builders in Greenville, SC

Trinity Exteriors builds new decks and replaces tired ones across Greenville and the Upstate, in Trex composite or wood, with stairs and screened porches too. Billy comes out first, asks how you use the yard, and gives you a detailed price before anything is torn out. Then the crew tears out the old deck, builds the new one and leaves the yard tidy.

Questions

Deck questions, answered

What Greenville homeowners ask before they build, answered.

Is the estimate really free?

Yes. Billy comes out, looks at the yard or the old deck, and gives you a detailed price at no cost. “Billy and the Trinity team was prompt on their estimate and it was very detailed and fair.” (Ken S.)

How much does a new deck cost?

It depends on the size, the height off the ground, composite or wood, and the rails and stairs. You get the number at the free estimate. Three of our deck reviewers ticked a price range on Google: one at $10,000 to $15,000 and two at $15,000 to $20,000. “The price was so reasonable - I thought he was missing something.” (Michael K.)

How long does it take to build a deck?

It depends on the size and the design, and you'll get a timeline with the estimate. One reviewer's deck took two days from tear-out to finish. “Demo'd fast and the frame build was so solid.” (Michael K.)

Should I build in composite or wood?

Composite costs more up front and skips the yearly sealing and staining. Wood costs less to build and needs that care to last. Billy walks you through both at the estimate. “They replaced an old wooden deck with Trex composite and I couldn't be happier with the results and price.” (Michael L.)

Can you replace my old deck and keep its design?

Yes. We tear out the old deck and build the new one, and we can keep a layout you love. Kendra W.'s 25-year-old deck, designed by her dad, was rebuilt in composite to the same design.

Do you clean up after the build?

Our customers say so. “Left the workspace all tidied up when they were finished.” (Palma H.)

Do you build screened porches and patio covers too?

Yes. We build screened porches on decks and aluminum patio covers for shade and rain cover. The photos above show both.

What areas do you serve?

Greenville and the Upstate, from our office at 1801 Rutherford Rd in Greenville. That includes Simpsonville, Greer, Easley, Travelers Rest, Spartanburg and Anderson.
