Common Mistakes to Avoid During Hardwood Floor Installation

Updated on
November 15, 2025

Hardwood floors bring timeless beauty and warmth to any home. Their longevity, easy maintenance, and ability to blend well with various interior designs are unmatched. However, to enjoy the benefits a hardwood floor offers, it needs to be installed right.

To ensure you get a highly functional floor, we’ve listed seven common mistakes you need to avoid during the installation process.

1. Failure to Acclimate the Wood

One of the most critical steps in hardwood flooring installation is acclimating the wood to its new environment. This process involves letting the wood adjust to the temperature and humidity of the room where it will be installed. Skipping this step can lead to wood expansion or contraction post-installation, causing buckling or gaps. Typically, wood should acclimate for a minimum of 3 days.

2. Forgetting to Check for Defects

Before installation, check each plank for defects. Sometimes, planks can have cracks, knots, or other imperfections that may affect the floor's durability and appearance. Replace defective planks or use them in less visible areas of the room.

3. Inadequate Subfloor Preparation

The subfloor is the foundation for your hardwood floors. Any imperfections in subfloor leveling can translate into squeaks and uneven surfaces on the new floor. Ensure the subfloor is clean, dry, and level. Use a leveling compound to fill any dips or sand down high spots. Testing moisture levels in the subfloor is crucial as too much moisture can cause wood to warp or crack.

4. Incorrect Measurement and Cutting

Measure twice, cut once is a golden rule in construction. Incorrect measurements can lead to wastage of materials and unsightly gaps or overlaps. Always leave a gap of about 3/8 to 1/2 inch around the edges to accommodate expansion due to temperature changes. This expansion gap should be covered by base molding or quarter rounds after the installation.

5. Improper Tools

Using the wrong tools, or improper use of the right tools, can damage the hardwood planks. Pneumatic flooring nailers or staplers should be used with care to avoid cracking the tongue of the planks. Ensure you are using the correct size of nails and that they fit correctly in the subfloor and not just the wood.

6. Overlooking the Finishing Touches

Final touches like applying the finish or sealant and attaching the baseboards are crucial. Ensure the sealant is applied evenly and adequately to protect the wood from moisture and wear. Also, allow the finish to dry completely before moving furniture back into the room.

7. Rushing the Process

Lastly, don’t rush the process. Hardwood flooring installation requires patience and precision. Rushing can lead to mistakes that are often difficult and expensive to rectify. Take your time to ensure each step is done correctly, from preparation to finishing.

Why is acclimating hardwood flooring before installation so important?

Acclimating allows the wood to adjust to the room’s temperature and humidity, reducing post-installation expansion, contraction, buckling, and gaps.

How should I inspect hardwood planks before installing them?

Check each plank for cracks, knots, warping, or other defects that could weaken the floor or hurt its appearance, and set flawed boards aside or use them in less-visible areas.

What tools are essential for correct hardwood floor installation?

You’ll need accurate measuring tools, a quality saw, a pneumatic flooring nailer or stapler with the right fasteners, and moisture meters—plus the skill to use them without damaging the planks.

We moved into a house that was more than 50 years old. Beneath our carpet was hardwood floors that we desperately wanted to keep. However, we were unsure if the gaps, scratches, and missing pieces of flooring could be fixed well enough to look normal. Not only did this company make it look “normal”, but it looked OUTSTANDING. They worked so hard and finished our floors while we were on our honeymoon, and it felt like we came home to a completely different house. They were very pleasant and great to work with!! HIGHLY RECOMMEND.

Absolutely in LOVE with our new hardwood floor! We went with a hand scraped hickory wood, a dark stain and a high gloss finish. It turned out better than I could have imagined. It completely changed the look of our home and made our living room feel much more cozy. I have already recommended you to some friends and cant thank you enough for making sure my wife was happy.

Mark from Classic Flooring went the extra mile for me. I needed to replace a bedroom carpet with laminate flooring before my tenant moved in. Another contractor had bailed on me at the last minute and I was scrambling to find a flooring contractor to complete the job on very short notice. Mark came to my rescue, all the way to Jackson Hole, Wyoming. I am eternally grateful to Mark for coming through for me on such short notice. Thank you, Mark!
