Question 1

What areas does Volunteer Decks serve?

Accepted Answer

Volunteer Decks is based in Knoxville, Tennessee and serves Knox County and the surrounding East Tennessee area, including Farragut, Maryville, Oak Ridge, Powell, Karns, Halls, and Corryton. We also build in the Nashville and Chattanooga markets. If you're not sure whether you're in our service area, send us your address through the quote form and we'll confirm.

Question 2

Are you licensed and insured?

Accepted Answer

Yes. Volunteer Decks is a licensed and insured Tennessee deck contractor. We carry general liability and workers' compensation coverage on every project, and we're a BBB-accredited business. We're happy to provide copies of our license and certificate of insurance on request.

Question 3

Do you pull building permits for deck projects?

Accepted Answer

Yes. For any deck that requires a permit under local code, we pull the permit, schedule the inspections, and handle the back-and-forth with the city or county building department. The permit fee is itemized in your written estimate so you can see exactly what it costs.

Question 4

How do I get an estimate for my deck project?

Accepted Answer

Start by filling out the quote form on our website or calling our office. We offer two estimate options: a remote estimate (we use satellite imagery, your photos, and a short call to scope the project) and an on-site estimate where we walk the property with you. Both are free and you get a written, line-item estimate within about 24 hours.

Question 5

Can you give me a real estimate without coming out?

Accepted Answer

Yes. Our remote estimate uses high-resolution satellite imagery, photos you share, and a 10-15 minute phone or video call. For most projects it's accurate enough to make a confident decision. For complex projects (multi-level, sloped lots, covered decks, full tear-outs) we recommend an on-site visit so we can measure heights and check site access.

Question 6

How much does a deck cost in Knoxville?

Accepted Answer

Deck pricing varies significantly with size, height, material, and railing choice. As rough ranges in the Knoxville market: a small ground-level pressure-treated wood deck typically starts in the low-to-mid four figures; a mid-size composite deck (Trex, TimberTech, or Deckorators) typically runs $15,000-$35,000; and larger multi-level or covered composite projects can run $40,000-$80,000 or more. We provide a written, itemized estimate after a remote or on-site consultation so you can see the cost of each material, the railing system, and labor broken out.

Question 7

What's the price difference between a wood deck and a composite deck?

Accepted Answer

Pressure-treated wood is the most affordable option upfront. Composite decking (Trex, TimberTech, Deckorators) generally costs 1.5-2x more than pressure-treated wood for the same size deck. The trade-off is maintenance: a wood deck needs cleaning and re-staining or sealing every 1-3 years, while composite decking only needs a soap-and-water wash and carries 25-to-lifetime manufacturer warranties. Over a 20-year window, composite often comes out cheaper once you factor in re-staining labor and materials.

Question 8

What factors affect the price of a deck the most?

Accepted Answer

The biggest cost drivers are (1) square footage, (2) deck height above grade (elevated decks need taller posts, deeper footings, and stairs), (3) decking material (pressure-treated wood is the floor, premium composites are the ceiling), (4) railing system (steel panel and cable systems cost more than our standard powder-coated stainless steel balusters), (5) features like covered roofs, screening, lighting, or built-in benches, and (6) site access and demo of an existing deck. We break all of these out in your estimate so it's clear where the dollars go.

Question 9

How long does it take to build a deck?

Accepted Answer

A standard pressure-treated wood deck typically takes 1-3 days of on-site construction once we break ground, depending on size and complexity. A composite deck (Trex, TimberTech, Deckorators) typically takes 2-6 weeks end-to-end including material lead time, with on-site construction itself often running 5-10 working days. Multi-level decks, covered decks, and projects with custom railings sit toward the longer end of those ranges. We give you a specific build window in writing before work starts.

Question 10

How long does it take to build a pressure-treated wood deck?

Accepted Answer

Most pressure-treated wood decks are framed, decked, and railed in 1-3 days of on-site work, assuming the design is straightforward and the site is accessible. Wood is the fastest material to build with because there's no lead time on supply.

Question 11

How long does it take to build a composite deck?

Accepted Answer

Composite decks typically take 2-6 weeks end-to-end. The bulk of that window is material lead time (1-3 weeks depending on collection and color) plus permitting. On-site construction itself usually runs 5-10 working days for a typical single-level deck and longer for multi-level or covered builds.

Question 12

When is the best time of year to build a deck in East Tennessee?

Accepted Answer

We build year-round in East Tennessee. Spring and early summer are our busiest seasons (book 4-8 weeks in advance), while late fall through winter is often a great time to schedule: lead times are shorter, the heat isn't a factor, and your deck is ready before the next spring. Concrete footings can be poured down into the 30s and 40s without issue.

Question 13

What deck materials do you install?

Accepted Answer

We install pressure-treated wood (the most affordable option), Trex composite decking (we're a Trex Platinum Pro dealer), TimberTech AZEK decking (we're a TimberTech AZEK Pro dealer), and Deckorators mineral-based composite decking. For railings we install powder-coated stainless steel balusters, composite railings, cable railings, and Fortress steel railings. Most projects pair one decking line with a complementary railing system that fits the budget.

Question 14

Should I choose wood or composite decking?

Accepted Answer

Choose pressure-treated wood if upfront cost is the priority and you're comfortable with cleaning and re-staining the deck every 1-3 years. Choose composite (Trex, TimberTech, or Deckorators) if you want to skip the ongoing maintenance, want a longer warranty (25 years to lifetime), and don't mind paying 1.5-2x more upfront. For most homeowners who plan to stay in the house 7+ years, composite ends up being the lower lifetime cost.

Question 15

What's the difference between Trex, TimberTech, and Deckorators?

Accepted Answer

All three are premium composite decking lines and all three are excellent products. Trex is the largest brand in the U.S. and offers the widest color and price range, from value (Enhance) to premium (Transcend, Lineage). TimberTech (owned by AZEK) makes a polymer-capped PVC line that's the most fade- and stain-resistant of the three, with up to 50-year warranties on top collections. Deckorators uses a mineral-based composite (MBC) that's cooler underfoot, pool-rated, and carries a lifetime structural warranty. We carry all three so we can match the right material to your budget, color preference, and use case (pool, kids, pets, full sun, etc.).

Question 16

What does the deck building process look like from start to finish?

Accepted Answer

The process typically runs: (1) quote request and estimate (1-2 days), (2) design refinement and material/color selection, (3) signed contract and deposit, (4) permit pulled, (5) materials ordered, (6) on-site demolition of any existing deck, (7) frame, deck, and railing installation, (8) final inspection, (9) walkthrough with you. You get a single point of contact throughout and a specific build window in writing before we start.

Question 17

Will my yard be torn up during construction?

Accepted Answer

We minimize site disruption. Footings require small post-hole excavations (typically 12-18 inches across and 36+ inches deep) and material staging needs a clear path from your driveway to the build site. We protect landscaping where we can, clean up debris daily, and haul away demo materials. Most yards look the same a week after the project as they did before, with minor seed-and-straw needed around the new footings.

Question 18

Can you build a deck over an existing concrete patio?

Accepted Answer

In many cases, yes — we can build a low-profile deck on top of an existing concrete patio using sleeper systems or specialized pedestals. The patio needs to be in good shape (no major cracks or settling) and drainage needs to be considered. We'll evaluate this during the estimate and tell you whether it's a good fit or whether removing the patio is the better call.

Question 19

Can you tear down my existing deck and build a new one?

Accepted Answer

Yes. Tear-out and rebuild is one of our most common projects. We'll inspect the existing structure during the estimate, quote the demo cost separately from the new build, and haul away all the old material. If portions of the existing frame are salvageable and meet current code, we'll let you know and price both options.

Question 20

What warranty do you offer on deck construction?

Accepted Answer

Every project includes a 5-year workmanship warranty on labor and installation, in writing. Materials are covered by the manufacturer's warranty (Trex: 25-year fade & stain; TimberTech: up to 50-year fade & stain on top collections; Deckorators: lifetime structural; pressure-treated lumber: per supplier terms). We also include a free annual inspection for the first two years and lifetime support. The workmanship warranty is transferable, which adds value if you sell the home.

Question 21

What does your workmanship warranty cover vs. the manufacturer's warranty?

Accepted Answer

Our 5-year workmanship warranty covers defects in our labor and installation — anything we did that turns out to be wrong. The manufacturer warranties (Trex, TimberTech, Deckorators, etc.) cover defects in the material itself: fading, staining, structural failure, that kind of thing. If you ever have an issue, contact us first and we'll handle the diagnosis and any warranty filing on your behalf.

Question 22

How long does Trex decking last?

Accepted Answer

Trex composite decking is engineered to last 25-30+ years with minimal maintenance. Trex Transcend, Lineage, and Signature collections come with a 25-year limited fade & stain warranty in addition to the standard 25-year limited residential warranty. Most Trex installations from the early 2000s are still in service today.

Question 23

Does Trex decking get hot in the sun?

Accepted Answer

Trex is a capped composite, so it gets warmer than wood in direct summer sun — that's true of all composite decking. The Trex Lineage collection is specifically engineered with heat-reflective technology and runs measurably cooler than Trex Transcend or Enhance. If your deck is in full sun all day or you walk barefoot frequently, we usually recommend a lighter Lineage color or stepping up to a cooler material like Deckorators mineral-based composite.

Question 24

What does it mean that Volunteer Decks is a Trex Platinum Pro dealer?

Accepted Answer

Platinum Pro is Trex's highest installer tier, awarded to contractors with proven volume, training, and customer-satisfaction track records with Trex products. Platinum Pro installers get access to Trex's full product line, manufacturer support, and warranty-claim handling. For you it means we install Trex decks all the time — we know which collections work in which conditions and we have direct lines to Trex if anything ever needs to be addressed.

Question 25

How long does TimberTech decking last?

Accepted Answer

TimberTech's AZEK PVC decking is the longest-warrantied composite on the market, with up to a 50-year fade & stain warranty on the Vintage, Landmark, Legacy, and Reserve collections. The polymer construction (no wood fiber in the AZEK lines) means it won't rot, mold, or stain even in heavy moisture. Real-world lifespan is 50+ years.

Question 26

TimberTech vs Trex — what's the difference?

Accepted Answer

Trex and TimberTech are both premium composite decking brands. The biggest technical difference is the substrate: Trex is a wood-and-plastic composite with a polymer cap, while TimberTech's AZEK lines are full polymer (no wood fiber) — that makes them more fade-, stain-, and scratch-resistant, and they carry longer warranties (up to 50 years vs. Trex's 25). TimberTech AZEK is generally the more premium product on price; Trex offers a wider range from value (Enhance) to premium (Transcend) and a larger color palette. We carry both and pick based on your budget and the look you want.

Question 27

What is AZEK and why does it matter?

Accepted Answer

AZEK is TimberTech's premium polymer (PVC) decking line. Unlike traditional composite decking which mixes wood flour with plastic, AZEK is 100% polymer — no organic material to fade, stain, mold, or absorb moisture. AZEK boards are also significantly lighter than wood-composite boards, which makes them easier to work with on multi-level builds. AZEK Pro is the installer designation for the AZEK product line.

Question 28

What is mineral-based composite (MBC) decking?

Accepted Answer

Mineral-based composite (MBC) is Deckorators' proprietary decking formulation that replaces wood fiber with mineral particles. The result is a decking board that's lighter, stronger, and dimensionally stable across temperature changes — it doesn't expand and contract like wood-composite. MBC is also pool-rated (won't be damaged by chlorinated water) and runs cooler underfoot than traditional composite, which is a real benefit in full-sun applications.

Question 29

Is Deckorators decking pool-rated?

Accepted Answer

Yes. Deckorators is the only major composite decking line that's officially pool-rated, meaning it's warrantied for use directly around chlorinated and salt-water pools without restrictions. The mineral-based composite construction doesn't absorb water or degrade from pool chemistry. If you're building a pool deck, Deckorators is usually our first recommendation.

Question 30

Why would I choose Deckorators over Trex or TimberTech?

Accepted Answer

Deckorators is the right choice when you want (a) the coolest underfoot temperature in full sun, (b) a pool-rated deck, (c) the lightest, most dimensionally stable boards, or (d) the lifetime structural warranty. Trex and TimberTech remain strong choices for color selection and (in TimberTech's case) ultra-long fade warranties. We'll walk you through samples of all three so you can decide based on the in-person look, feel, and cost.
