Top 5 Mistakes to Avoid When Building a Deck in Northern Virginia

What we’ve seen go wrong—and how we make sure it doesn’t happen to you

A well-designed deck adds more than square footage—it adds comfort, resale value, and daily enjoyment to your home. But like any serious construction project, success comes down to details. In our experience across Northern Virginia, we’ve seen how cutting corners or skipping the fundamentals leads to regret, repairs, and missed potential.

At Crespo & Company, we believe in doing it right the first time. Here are five of the most common mistakes we see homeowners make when building a deck—and how we help clients avoid them.

1. Skipping Permits or Underestimating Code Requirements

Each jurisdiction in Northern Virginia—Fairfax, Arlington, Loudoun—has its own set of building codes, structural requirements, and review processes. Ignoring or underestimating these doesn’t just slow the project—it can result in fines, failed inspections, or required tear-downs.

How we handle it:
We take full responsibility for the permitting process, including engineering, zoning, and inspections. From the start, your project is code-compliant and legally sound.

2. Choosing Materials Without Understanding Maintenance

Not all decking is created equal. Pressure-treated lumber may be cheaper upfront, but it requires frequent sealing and can warp over time. Composites like Trex or TimberTech offer a low-maintenance solution—but they still require proper installation. And hardwoods like Ipe or Tigerwood add beauty, but demand precision and planning.

How we help:
We walk you through the long-term performance, maintenance, and visual differences of each option so you can invest with confidence—not guesswork.

3. Working with a Builder Who Doesn’t Prioritize Design

Too many decks feel like an afterthought—poor traffic flow, awkward stairs, or proportions that just don’t feel right. A deck should match your home’s architecture and lifestyle—not just fill space.

How we work:
As a design-build firm, we focus on proportion, layout, railing lines, and finishes that make your deck feel fully integrated—not bolted on. Whether it’s a curved layout, floating steps, or picture-framed composite borders, design is never secondary.

4. Overlooking Site Conditions

Elevation changes, water runoff, soil stability, or tree root systems can dramatically affect how a deck should be built. Builders who skip this analysis often create structures that sink, settle, or rot prematurely.

What we do differently:
Every Crespo deck begins with a site assessment. We evaluate everything beneath and around the build zone so that the final structure is strong, stable, and built to last.

5. Choosing the Lowest Bid Without Understanding What’s Included

The lowest price doesn’t always mean the best value. Thin scopes, vague contracts, or corner-cutting can turn into expensive fixes later on. Rushed framing, exposed fasteners, or misaligned railings aren’t just cosmetic—they’re structural concerns.

How we build trust:
Our estimates are detailed, transparent, and built around long-term performance. We don’t compete on price—we compete on quality, clarity, and the strength of our work.

A Smart Deck Is a Long-Term Investment

Done right, your deck becomes a permanent part of how you enjoy your home. Done wrong, it becomes a recurring headache. These five mistakes are easy to avoid when you partner with the right team—and they’re exactly what we protect our clients from.

At Crespo & Company, we bring construction expertise, design precision, and total transparency to every outdoor project we build.
