FAQ

Questions, Answered

Curious about thermally modified wood? Below you'll find quick answers to the most common questions about what it is, how it's made, and why it's a smart choice for your next project.

Yes, upfront — and it's worth it. Pressure-treated lumber requires ongoing maintenance, staining, and eventual replacement. Modified wood is designed to last decades with minimal upkeep and no chemical retreatment. When you factor in the lifetime cost of maintenance and replacement, modified wood typically wins. Call us and we can help you compare the numbers for your specific project.

Modified wood is real wood — it has the warmth, grain, and natural feel that composite can't replicate. It also stays cooler underfoot than composite in direct sun, which matters in Florida and Southern California. Composite has its place, but if you want the look and feel of real wood with the durability of a modified product, this is the category to be in.

Generally, no — all of the brands we carry can be left untreated and will weather naturally to a silver-gray patina over time. If you want to preserve the original warm caramel tone, a UV-protective oil or coating can be applied. None of these products require annual retreatment the way traditional wood does.

Decking, exterior cladding and siding, soffits, pergolas, feature walls, interior paneling, docks, boardwalks, fencing, and site furnishings — the brands we carry collectively cover all of these applications. Call us with your project details and we'll point you to the right species and profile.

That depends on your species preference, profile requirements, application, warranty needs, and budget. Our team works with modified wood every day and can help you narrow it down quickly. Call us at 877-559-6299 and give us the basics — we'll do the rest.

We carry modified wood inventory at our Miami, New Jersey, and California locations. Availability by species, brand, and profile varies — call us to confirm what's in stock and what can ship to your project timeline.
