Should You Build Your Own Deck? DIY vs. Hiring a Pro in Southeast Michigan
Building your own deck is a real option for some homeowners. We build decks for a living, and we’ll still tell you that. A small, low, freestanding deck is a reasonable weekend project for someone with solid carpentry skills.
Most decks in Southeast Michigan aren’t that project. They attach to the house, sit above grade, need 42-inch frost footings dug through clay, and have to survive decades of freeze-thaw cycles and heavy snow. That’s where the gap between a DIY deck and a professionally built one gets wide.
This guide walks through what building your own deck actually involves, what it really costs, and when a professional build is worth the investment.
When Building Your Own Deck Makes Sense
DIY can be a good fit if your project checks most of these boxes:
- Low to the ground, generally under 30 inches
- Freestanding rather than attached to your house
- Simple, rectangular layout
- Pressure-treated lumber rather than composite or PVC
- No electrical, gas, plumbing, or hot tub
- You have real carpentry experience and the tools already
If that describes your deck and you enjoy the work, go for it. Build it well, pull the permit, and have fun.
If your project involves a second story, multiple levels, a wraparound, composite or PVC decking, built-in lighting, or a dry space underneath, keep reading.
What DIY Actually Involves in Southeast Michigan
The build is only one part of the work. Before you drive a single screw:
Call MISS DIG 811. Michigan law requires you to contact MISS DIG at least three business days before digging so underground utilities can be marked. Hitting a gas or electric line is not a fun way to learn this.
Pull the permit yourself. As a homeowner-builder, you’re responsible for submitting drawings, scheduling footing, framing, and final inspections, and fixing anything the inspector flags. Our deck permit guide explains the process.
Dig frost footings. Footings in most of Southeast Michigan must reach at least 42 inches deep to get below the frost line. In dense clay soil, that’s hard labor, and it’s where many DIY decks cut corners that show up years later as sagging and heaving.
Get the ledger right. The connection between your deck and your house is the most common failure point in deck collapses. It needs correct fasteners, correct spacing, and proper flashing so water doesn’t rot your home’s framing.
Design for snow load. Joist spacing, beam sizing, and post placement all have to handle heavy, wet Michigan snow sitting on the deck for weeks.
Follow manufacturer installation rules. Composite and PVC decking have specific requirements for spacing, fasteners, and joist support. Install them wrong, and you may void the material warranty.
Tools, Materials, and Time
Tools: A structurally sound deck takes much more than a drill and a circular saw. Expect post hole diggers or an auger, a miter saw, a table saw, levels, framing and speed squares, clamps, and specialty fastening tools for hidden-fastener composite systems. If you don’t own them, buying or renting them adds up quickly.
Materials: You’ll need a precise cut list covering every board, joist, hanger, and fastener. Underestimate, and you’re making extra trips. Overestimate, and you’re storing leftover lumber. Composite and PVC decking and quality railing systems are often easier to source through a contractor than at the big-box store.
Time: A professional crew with the right equipment works full days, back to back. A DIY build usually happens on weekends. A deck that takes an experienced crew a few days can easily stretch into two months of Saturdays for a homeowner, and that’s before rain delays or a failed inspection.
The Real Cost Comparison
DIY looks cheaper because you’re not paying for labor. The full picture includes:
- Tools you’ll need to buy or rent
- Material overages and return trips
- Delivery fees if you don’t have a truck
- Permit and inspection fees
- Rework if an inspection fails or a cut goes wrong
- A voided material warranty if installation doesn’t follow manufacturer guidelines
- Your time: every weekend spent building is a weekend not spent using the deck
And the most expensive outcome of all: tearing out a failing DIY deck and paying a professional to build it again.
A professional build costs more upfront. What you’re paying for is certainty: a clear price, a finished deck built to code, and a warranty backing the work. At SpaceStars, that’s a 30-year workmanship warranty. Your DIY deck’s warranty is you.
What a Premium Deck Builder Delivers That DIY Can’t
Hiring a professional isn’t just about outsourcing labor. A premium deck builder brings things you can’t replicate with a free weekend and a YouTube tutorial.
Custom design. A good builder designs around how you’ll actually live on the deck: dining, lounging, entertaining, sightlines from the kitchen, sun and shade through the day, and how it connects to your yard.
Premium materials installed correctly. High-performance composite and PVC decking and railing systems deliver 25 to 30 years or more of low-maintenance use, but only when installed to manufacturer specifications. Certified installers are trained by the manufacturer. See our comparison of deck materials.
Structural engineering and code compliance. Footings, beams, ledger attachment, guard heights, and stair geometry are designed to pass inspection the first time and hold up for decades in Michigan’s climate.
Features that are hard to DIY. Multi-level designs, wraparounds, integrated lighting, curved edges, and under-deck drainage systems that turn the space below a raised deck into usable, dry living space.
Project management. One point of contact handles permits, scheduling, inspections, and updates, so you’re not the general contractor on your own house.
A long-term warranty. If something isn’t right, it’s the builder’s responsibility to fix it, not yours. The length of a workmanship warranty tells you how long a builder expects their work to last.
Is a Premium Deck Build Worth It?
A professionally designed and built deck makes the most sense when:
- You plan to stay in your home for years and want something built to last decades
- Your deck is attached, elevated, multi-level, or larger than a simple platform
- You want composite or PVC materials with low maintenance
- You’d rather spend your summer on the deck than building it
- The deck is a major part of how your home looks, functions, and sells
A deck is one of the most visible parts of your home. It’s worth building once and building right.

Frequently Asked Questions
Can I legally build my own deck in Michigan?
Yes. Homeowners can generally pull a permit and build their own deck, but you’re responsible for meeting code and passing every inspection. Rules vary by city and township, so check with your local building department first.
Do I need a permit to build my own deck?
Almost always, especially for decks attached to the house or more than 30 inches above grade. Building without one can cause problems when you sell your home.
How much does it cost to build your own deck vs. hiring a contractor?
DIY saves on labor, but tools, material overages, permits, rework, and your time narrow the gap. For attached, elevated, or composite decks, the gap narrows even more once you factor in the risk of doing it wrong.
Will building my own deck void the decking warranty?
It can. Composite and PVC manufacturers require installation according to their guidelines. Incorrect spacing, fasteners, or joist support can void the material warranty.
What warranty comes with a professionally built deck?
It varies by builder. One to five years is common. SpaceStars backs every deck with a 30-year workmanship warranty, separate from the manufacturer’s material warranty.
How long does it take to build a deck?
A professional crew can typically complete the build in days to a few weeks once permits are approved. A DIY build on weekends often takes several months.
Is a composite deck harder to install than wood?
Composite and PVC require more precision. Joist spacing, board gapping, hidden fastener systems, and allowances for thermal expansion all matter. Mistakes are harder to fix and can affect both appearance and warranty.
