Have Questions?

What makes A-DIY different from traditional deck building?

A-DIY is the first company in the world to offer professional, contractor-grade deck kits that anyone can assemble. Our patent-pending design eliminates cutting, measuring, and guesswork—everything fits together perfectly, just like Lego. The only tool you need is a hand drill, making it simple even if you’re not a handyman.

Why should I choose A-DIY over hiring a contractor?
  • Save thousands on labor costs.
  • No delays or hidden fees—know exactly what you’re paying for.
  • Install in under an hour, instead of waiting weeks for a contractor.
  • Enjoy a professional-grade deck with minimal effort.
Do you build custom-sized decks?

No, we offer pre-engineered deck kits in popular sizes to keep the process simple, affordable, and stress-free. 

I’m not sure what deck size I need. Can you help?

Absolutely! You can send us pictures and measurements of your space, and we’ll connect you with a senior design consultant to recommend the best size for your needs.

Can I attach multiple decks together?

Yes! Our decks are modular, so you can combine multiple kits to create a larger or uniquely shaped deck.

Can I trim or modify the deck?

We do not recommend modifying our decks, as they are engineered to fit together perfectly. Any modifications may compromise the structure and void the warranty.

What materials do you offer?

We offer two premium materials, all designed to last 20+ years:

  • Kiln Dried Pressure-Treated Lumber – Highly durable and cost-effective.
  • Composite – A modern, low-maintenance solution with a 25-year warranty.
What is the subfloor made of?

Our subfloors use kiln-dried pressure-treated lumber, with 6x6 beams and 2x8 joists for extra durability. The joists are spaced 14 inches apart, making the deck incredibly sturdy.

How does the deck hold up in storms and strong winds?

Our decks are sturdy and secure when properly installed. For areas with high winds, we recommend using cemented footings or sonotubes for added stability.

Can I put a gazebo or hot tub on my deck?
  • Gazebo: Yes! Just make sure it is securely fastened to the deck.
  • Hot Tub: If the deck is ground-level, yes! If elevated, check with a structural professional to ensure proper support.
Is this deck strong enough for heavy furniture?

Yes! Our decks are built to contractor-grade strength and can support typical outdoor furniture, grills, and lounge setups with ease.

What comes with the deck kit?

Every kit includes pre-cut, precision-engineered materials, screws, footings, and an easy-to-follow assembly guide. It arrives ready to assemble, so there’s no need for extra tools or multiple trips to the hardware store.

How easy is it to assemble the deck?

Our decks are designed to be assembled in under an hour using just a drill. No special tools, cutting, or measuring required—everything fits together seamlessly like Lego.

Can I elevate the deck?

Yes! Our decks are designed for ground-level installation, but you can elevate them using longer posts. We recommend keeping the height within 15 to 43 inches (3 to 4 steps) for best stability. If you want to go higher, consider cemented footings or sonotubes for additional support.

Can I move or disassemble the deck?

Yes! Our decks can be disassembled and moved if needed, making them perfect for temporary or semi-permanent installations.

Do I need a permit to install this deck?

Permit requirements vary by location. You should check with your local building authority. If needed, we can provide engineering diagrams to assist with your permit application.

Do you offer financing?

Yes! We’ve partnered with Affirm to offer:

✔️ 0% interest for up to 24 months

✔️ $0 down payment options

Do you have a physical store where I can see the decks in person?

Currently, we do not have a physical store, but we are expanding our warehouses across the U.S. for faster shipping. You can check out customer reviews and photos on our website.

  • Processing: Orders are prepared within 2–3 days.
  • Shipping: Delivery takes 7–14 days, depending on location.
  • Tracking: You’ll receive updates via email and text.
