Here's What Matters: When shopping for a dock kit, focus on size and weight capacity, what’s included (and the quality of it), and what’s not included. A good kit uses durable floats, heavy-duty hardware, and doesn't skimp on important pieces. Don’t forget — you’ll often need to buy framing and decking separately.
When you’re ready to build your own dock, finding the right DIY dock kit can make all the difference between a smooth, satisfying build and a frustrating one. But not all kits are created equal — and what looks like a great deal at first can turn into headaches (and added costs) later. Here’s what you should really be looking for before you click “add to cart.”
1. Size and Weight Capacity
Before anything else, consider what you’re using your dock for. Is this a small swim platform? A fishing dock? A party boat exit point with 40+ people on it?
A good dock kit should clearly state both its total size and maximum weight capacity. You’ll want to make sure it provides enough buoyancy to keep your dock safely above water even when it’s loaded up with people, gear, or furniture.
It's crucial to remember that not all dock kits have the same dimensions, or weight capacities. Some cheaper dock kits can be the same length and width, but because they use smaller, cheaper floats, their buoyancy can be far lower, leading to much less capacity for people, furniture, or other loads on your dock.
If you’re not sure how to calculate what you need, check out our guide on dock float buoyancy (or contact us — we’re happy to help and create a custom kit for you). The short version: always plan for more load than you think you’ll have. It’s much easier to enjoy a dock that’s extra stable than one that starts dipping below the waterline every time your friends walk out on it.
2. What’s Included — and What Quality It Is
Next, take a close look at what’s actually included in the kit.
At The Dock Shop, our kits are built with Eagle floats and heavy-duty galvanized hardware designed to last for years — even under stress and constant exposure. One of the biggest differences you’ll notice is in our inside corner pieces. These are the unsung heroes of a dock’s structure, keeping it square and true over time. Many cheaper kits use lighter outside corners and backer plates, but those setups can twist, warp, or loosen after just a few seasons.
When you’re comparing kits, look beyond the surface. Quality hardware isn’t just about appearance — it’s what holds your dock together under pressure.
3. What’s Not Included
Here’s a big one that catches a lot of DIYers off guard: most dock kits aren’t fully complete. If the kit is meant for using lumber as framing and decking, that is probably not included.
That doesn’t mean the kit isn’t a great starting point — it just means you’ll need to plan for those materials separately. Before purchasing, make sure you’ve mapped out everything you’ll need from start to finish: framing, decking, anchoring, and tools. Our DIY guides can help you estimate your lumber needs and plan your build step-by-step.
Final Thoughts
Choosing a dock kit isn’t just about price — it’s about performance, longevity, and peace of mind. When you choose a quality kit with durable floats, reliable hardware, and a clear understanding of what’s included, you’re setting yourself up for years of enjoyment on the water.
