How to install hardwood floors on concrete is one of the most common questions homeowners ask when upgrading their space—and for good reason. Concrete subfloors are solid, but they require a different approach compared to wood subfloors. If you’re in Apex, NC, working with a trusted local expert like Bradley’s Flooring & Tile can make the difference between a long-lasting floor and costly mistakes.
Bottom line: Putting down hardwood over concrete is doable, but not for the novice. Things like moisture control, proper underlayment and appropriate installation methods all play an important role. Here are the basics you need to know before even thinking about laying your very first plank.
Key Takeaways
- Concrete subfloors require moisture testing before installation
- Engineered hardwood is usually a better option than solid hardwood
- Proper underlayment is critical for stability and durability
- Installation methods vary: glue-down, floating, or nail-down with subfloor
- Professional installation helps avoid warping, buckling, and costly repairs
2 Ways to Install Hardwood on Concrete (and Why It Matters)
Concrete holds moisture—that’s the biggest issue. Even when it looks dry, vapor can still rise through the slab and create conditions that damage hardwood over time.
But, by all means: always check the moisture content first before you install. One of the most common reasons for floors to fail is skipping this step.
Further, not every hardwood will do. Concrete creates problems with solid hardwood being a more aggressive player in how much it expands and contracts. This is why most professionals—Bradley’s Flooring & Tile included—suggest using engineered hardwood for Apex, NC houses.
Follow These Step-By-Step Instructions For Installing Hardwood Floors On Concrete
Test the Concrete for Moisture
Here’s what matters: moisture control.
Moisture meter or calcium chloride test If the moisture is high you will require vapor barrier of moisture mitigation system.
Skipping this step? And that is how floors get buckled within weeks.
Prepare the Surface
It must be level, clean, and smooth concrete
- Remove dirt, dust, and debris
- Fill cracks or holes
- Grind down high spots
Even the slightest imperfections can have an impact on how your flooring sits. It ensures that you have a flat surface for the long term.
Choose the Right Hardwood
You’ve got two main options:
Engineered hardwood – Ideal for concrete and more stable.
Solid hardwood — Not advised unless you add a plywood subfloor
Most Apex homeowners opt for engineered hardwood because it tolerates humid conditions better.
Install a Moisture Barrier
This is non-negotiable.
A vapor barrier protects your flooring from moisture migrating up through the concrete. This will however depend on the method as this could be:
- Plastic sheeting
- Liquid moisture barrier
- Underlayment with built-in protection
People do this and they are experts in it like Bradley’s Flooring & Tile; If this is wrong, everything else is destroyed.
Pick the Installation Method
How to Install Hardwood Over Concrete
Glue-Down Method
The adhesive is applied directly on the concrete
Provides a solid, stable feel
Best for engineered hardwood
Floating Floor Method
Locking planks without being glued to the floor
Installed over an underlayment
Easier but requires precision
Nail-Down (with Subfloor)
Must first install plywood over concrete
More labor-intensive
Used for solid hardwood
Almost always, homeowners choose a glue-down or floating system.
Acclimate the Flooring
That means hardwood has to acclimatize itself to the climate of your house.
Install the planks only after letting them acclimatize for 48–72 h in a dry and clean room. This requires less expansion and contraction later on.
Install the Flooring
This is where precision matters.
Start along the longest wall
Maintain consistent spacing
Follow manufacturer guidelines
A single inaccurate cut or misalignment could spoil the whole floor.
Finishing Touches
Once installed:
- Add baseboards or trim
- Clean the surface
- Look for any gaps or uneven surfaces
A specialist installer will also ensure long-term stability.
Common Mistakes to Avoid
Straight up—most DIY efforts go down due to these:
Skipping moisture testing
That is using an improper type of hardwood
Poor surface prep
Incorrect adhesive or underlayment
Rushing the acclimation process
Inevitably, these errors lead to warping and gaps which, of course, result in expensive repair bills. This is why a lot of Apex, NC house owners opt for professionals instead.
