So, you're looking to get a new Trex deck? That's awesome! It's a really great product, and if it's installed correctly, it'll last you for ages without much fuss. But, having done this work in Boulder for a good while now, I've definitely seen where folks tend to stumble. It's usually not the material itself that causes issues; it's more about how you plan and who you hire. Let's go over some common mistakes I spot homeowners making and how you can easily avoid them.
Mistake #1: Not Getting Detailed Bids (Beyond Just the Price)
This one's a big deal. You call three contractors, they each give you a number, and you just pick the cheapest one. Sounds smart, right? Not always, actually. A bid isn't just a price tag; it's basically a promise of what you're actually going to get. When I put together a bid for Boulder Deck & Porch, it's super thorough. We're talking really specific stuff:
- Which Trex board exactly? (There are different lines – like Enhance, Select, Transcend, and they all have different prices and perform a bit differently.)
- What kind of fasteners will they use? (Hidden clips or screws visible on the surface? This changes both the look and the cost.)
- What's the framing material going to be? (Pressure-treated lumber is pretty standard, but some might suggest steel or aluminum, which is a whole different ballgame.)
- Are permits included in the price? (For any structural work in Boulder, they really should be.)
- What about tearing out the old deck and hauling away the junk?
- Is railing part of the deal? And if so, what style?
- What's the warranty on the actual labor?
Without these kinds of specifics, you're basically trying to compare apples to oranges. A lower price could mean they're using a cheaper Trex line, less sturdy framing, or you might get hit with hidden costs down the road. Always, always ask for a detailed breakdown. If a contractor can't or won't give you one, well, that's a pretty clear warning sign, isn't it?
Mistake #2: Underestimating the Importance of Proper Footings for Boulder Soil
Boulder's expansive clay soils are no joke. We're not building on solid rock everywhere; sometimes you hit that clay, especially if you're in an older neighborhood like Martin Acres or even some parts of North Boulder. If your deck footings aren't designed and installed correctly for our freeze-thaw cycles and soil movement, you're going to have problems. I've seen decks heave, settle unevenly, and even pull away from the house because the footings weren't deep enough or wide enough, or they weren't bell-bottomed where needed. A good contractor knows this and will factor it into their plan. They won't just dig a shallow hole and pour some concrete. They'll know the local building codes and soil conditions. Don't let anyone skimp on the foundation of your deck.
Mistake #3: Ignoring the Deck's Orientation and Sun Exposure
You're building a deck to enjoy, right? But I've seen folks put a beautiful deck in a spot that gets absolutely blasted by the afternoon sun with no shade plan whatsoever. Or maybe they build it facing a direction that gets hammered by our strong westerly winds. Trex is tough, sure, but even it can get really hot in direct, unrelenting sun. So, think about how you'll actually use the deck. Do you need a pergola? Maybe a retractable awning? Or perhaps a strategically placed tree could do the trick? Talk about this with your contractor during the design phase. A good one will bring it up and help you plan for it, not just build a rectangle wherever you point.
Mistake #4: Not Checking References or Past Work
This seems obvious, but people get excited and just skip it. Don't just look at pretty pictures on a website. Ask for references, and actually call them. Ask about how the contractor communicated, if they were on time, how clean they kept the site, and how they handled any unexpected issues. Did they stick to the budget? Did they finish when they said they would? Also, ask to see a few of their completed projects in person if you can. You can tell a lot about the quality of the work by seeing it up close. Are the cuts clean? Are the railings solid? Is the flashing properly installed where it meets the house? Any reputable contractor will be proud to show off their work.
Mistake #5: Focusing Only on the Deck Surface, Not the Structure
Trex is a fantastic low-maintenance surface, but it's only as good as the structure underneath it. If the framing is poorly built, improperly spaced, or uses inferior materials, your beautiful Trex deck will sag, squeak, or even become unsafe over time. I've seen contractors try to cut corners by using smaller joists or wider spacing than code allows, especially for composite decking which requires tighter spacing than wood. Make sure your contractor is building to code, and ideally, exceeding it where it makes sense for longevity. Ask about the joist spacing and the type of lumber being used. A solid frame means a solid deck for decades.
Building a Trex deck is a big investment. Do your homework, ask tough questions, and don't be afraid to walk away if something just feels off. You want a deck that you'll love for years, not one that gives you headaches. Take your time, do it right, and you'll be enjoying your new outdoor space in no time.
