When you build a new deck, you’re not just adding boards and railings to your backyard. You’re investing in your home. You’re creating a space for summer barbecues, quiet mornings with coffee, birthday parties, and family time. But here’s a question many homeowners throughout the Twin Cities Metro don’t think about right away:
What’s holding it all up?
The surface of your deck may look beautiful, but the real strength is underneath. The frame is what supports everything. If the frame fails, the entire deck is at risk. That’s why Dupont Decks offers a Lifetime Deck Frame Limited Warranty, a workmanship warranty that ensures the structural frame is built to last.
In this article, we’ll explain what that warranty really means, what it covers, and why it matters for your long-term investment. If you’re planning to build a deck, understanding this could make all the difference.

What Is the Lifetime Deck Frame Limited Warranty?
A deck has two main parts:
- The visible surface, decking boards, railings, stairs.
- The structural frame underneath, joists, beams, and support posts.
Most homeowners focus on the surface. They choose colors, materials, and railing styles. But the frame is what carries the weight of people, furniture, grills, and snow during Minnesota winters.
Our Lifetime Deck Frame Limited Warranty means we stand behind the workmanship of the structural frame for as long as the original homeowner owns the deck at the property.
At Dupont Decks, this warranty applies specifically to the structural framing components that support your deck. That’s where long-term durability truly matters.
Why the Frame Matters So Much in Minnesota
Living throughout the Twin Cities Metro means your deck goes through a lot. Our climate includes:
- Heavy snow loads in winter
- Freeze and thaw cycles
- Spring moisture and rainfall
- Hot, humid summers
Over time, these conditions can stress any outdoor structure. If a deck frame isn’t built correctly from the start, small problems can turn into major repairs later.
That’s why structural quality matters more here than in many parts of the country. A well-built frame isn’t just helpful, it’s necessary.
What Our Lifetime Structural Warranty (On the Deck Frame We Build) Covers
Dupont Decks’ warranty focuses on the workmanship of the structural frame. That includes:
- Joists
- Beams
- 6×6 vertical support posts
These components form the backbone of your deck. If there is a defect in how they were built or installed, Dupont Decks will repair the issue at no cost to the original homeowner. No other deck components are covered under this warranty.
It’s important to understand that this is a workmanship warranty. That means it covers how the frame was constructed, not normal aging, cosmetic changes, or manufacturer material warranties.
If a covered structural issue arises due to workmanship, repair is the solution. That repair will be completed professionally and correctly. This warranty covers workmanship only, not material defects, which are covered separately by the manufacturer.
What “Lifetime” Really Means
The word “lifetime” can sometimes be confusing. In this case, it means:
- The original homeowner still owns the property.
- The deck remains at its original location.
- The deck is used for normal residential purposes.
- The structural frame has not been altered or modified.
The warranty automatically ends if the home is sold, the deck is relocated, the frame is modified, or the deck is used outside normal residential purposes.
The key takeaway? As long as you own your home and your deck remains in its original condition, Dupont Decks stands behind the structural workmanship.
Why Dupont Decks Can Offer This Warranty
Not every deck builder offers a lifetime structural warranty. So why can Dupont Decks confidently make this promise?
It comes down to how the deck is built.
High-Quality Framing Lumber
Strong decks start with strong materials. At Dupont Decks, we use #1 grade treated lumber in the construction of our deck frames. Many builders use lower-cost #2 grade lumber to reduce expenses, but we believe your deck’s structure deserves stronger materials. #1 grade lumber provides better strength, durability, and consistency, helping ensure your deck frame performs reliably for years to come.
Premium Fasteners
The hardware that holds a deck together matters just as much as the wood. Proper fasteners help prevent shifting, loosening, and long-term structural weakness.
Advanced Framing Techniques
Experience matters. With nearly two decades of construction experience throughout the Twin Cities Metro, the Dupont Decks’ team understands local building codes, soil conditions, and weather demands.
Every deck is built to meet or exceed Minnesota state building codes. That level of attention and care is what makes a lifetime warranty possible.
Built to Outlast the Surface
Decking boards and railing styles may change over time. Many homeowners upgrade their surfaces to low-maintenance materials like TimberTech or Azek. But the frame underneath remains.
The goal is simple: build the structure once and build it right.
What’s Not Covered (And Why That Makes Sense)
A strong warranty is clear about what it covers and what it does not.
The Lifetime Deck Frame Limited Warranty does not cover:
- Manufacturer defects in materials
- Deck footings, foundations, piers, or ground support systems
- Environmental issues like flooding or frost heave
- Alterations such as adding hot tubs or pergolas later
- Normal wear and tear
- Footing movement or ground-related issues such as soil settlement, frost heave, drainage problems, or expansive soils
- Any structural damage caused by environmental or site conditions outside Dupont Decks’ control
Minnesota soil and weather conditions can shift and change over time. While the frame workmanship is covered, outside factors like soil movement are not something any builder can fully control long-term.
This transparency builds trust. You know exactly what you’re getting.
Long-Term Value for Homeowners
A deck is a major investment. Many homeowners throughout the Twin Cities Metro spend years planning their outdoor living space. They want something beautiful, but also something secure.
A strong structural warranty protects you from unexpected repair costs caused by poor workmanship. It also shows that the builder believes in the quality of their work.
