Mistake #1: Skipping Moisture Testing

Why Moisture Matters

Moisture is a silent floor killer. Even a small amount can cause warping, cupping, or mold—especially with hardwood.

Imagine spending thousands on hardwood only to have it bubble up after a rainy week. Yikes!

How to Properly Test for Moisture

You’ll want to test both your subfloor and the hardwood itself. This ensures compatibility and avoids later expansion or contraction issues.

Best Tools for Moisture Testing

  • Moisture meters (pin or pinless)
  • Hygrometers for room humidity
  • Calcium chloride tests (for concrete subfloors)

Make this step part of your routine or consult our guide to flooring tools and materials.


Mistake #2: Ignoring Subfloor Issues

Uneven Surfaces Spell Trouble

A subfloor that’s bumpy, cracked, or loose? That’s a recipe for squeaky, uneven flooring.

Identifying and Fixing Subfloor Problems

Before you install, walk across the room and listen for creaks. Check for dips or raised spots. Use a level across the floor. If you spot issues, sand high points, fill low ones, or replace damaged panels.

This step is also covered in our DIY flooring installation guide—highly recommended if you’re going the DIY route.


Mistake #3: Not Letting the Hardwood Acclimate

What is Acclimation?

Hardwood is a natural material. It expands and contracts based on the room’s humidity. If it’s not allowed to adjust (aka acclimate) before installation, it’ll move after it’s nailed down—and not in a good way.

The Right Way to Acclimate Hardwood

Bring the flooring into the room it’ll be installed in and leave it for at least 3–7 days. Keep the boxes open and boards spread out for airflow. Don’t skip this—it’s your floor’s adjustment period!

Mistake #4: Using the Wrong Underlayment

Choosing the Right Underlayment for Hardwood

Not all underlayments are created equal. For hardwood, you need moisture protection and sound reduction.

Some popular options include:

  • Felt underlayment
  • Foam with vapor barriers
  • Rubber for high-traffic areas

Common Underlayment Errors to Avoid

  • Skipping it entirely
  • Choosing carpet padding (never do this!)
  • Not sealing seams

Choosing wisely can prevent moisture buildup and provide stability. Visit our underlayment tag for expert advice.


Mistake #5: Poor Cleaning and Debris Removal

Why Clean Surfaces Are Critical

A dirty floor base is a bumpy floor waiting to happen. Dust, nails, or debris will affect how well the boards lay and connect.

Tips for Effective Cleaning Before Installation

  • Sweep and vacuum thoroughly
  • Mop using minimal water (remember moisture!)
  • Double-check corners and edges

How to Prepare Like a Pro

Use a Detailed Prep Checklist

Write down every step—moisture check, subfloor repair, cleaning, acclimation, underlayment. Tick them off as you go. This keeps you on track and reduces stress.

Hire or Consult with Experts When Needed

FAQs

1. What happens if I skip moisture testing before hardwood installation?
You risk floor buckling, warping, or mold. Moisture is one of the top silent killers for hardwood flooring.

Use a long level or straight edge. If you see gaps or rocking, that area needs sanding or filling.

3. Can I install hardwood the same day it’s delivered?
Nope! Let it acclimate for at least 3–7 days in the room it’ll be installed in.

4. Do I need underlayment for hardwood on concrete?
Yes! Always use a moisture barrier plus padding. It helps with both insulation and longevity.

5. Can I use the same underlayment for all flooring types?
No. Each material—hardwood, laminate, vinyl—has specific underlayment requirements.

6. Is cleaning the subfloor really that important?
Absolutely. Even small debris can cause unevenness and installation issues.
