Frequently Asked Questions

All of our Modern Ash Decking is made from clear grade Ash that is sourced, milled and sealed in our North American production facilities. Each piece is thermally treated for added durability and stability before it is fully sealed on all 4 sides.

This is dependent on your vision and preferences for design. The siding can be installed with no regular maintenance required which will allow the wood to develop into a beautiful silver color over time. If you wish to maintain or restore the original color of the Modern Exterior Cladding, you can apply a fresh coat of oil based sealant (Thompson’s WaterSeal Clear or Ready Seal) at any time.

All of our exterior decking options are treated to withstand weather of all types - hot sun, dry climates, humidity, or rainy seasons. Our Modern Ash Decking is naturally water repellent due to the thermal treatment process, and then we take the added step of applying a UV resistant treatment and oil based sealant on all 4 sides.

We ship anywhere in the country in 3-4 weeks via UPS or an LTL carrier (we send tracking information once it ships).

We accept returns/exchanges within 30 days from your original order date. Please refer to our Refund Policy here.

Installation is super simple! We recommend using a hidden fastener system for the best result and appearance. Full instructions are included with every order.
