Preparing for Hardwood Flooring Installation: A Complete Guide

Installing hardwood flooring is an investment that adds beauty, durability, and value to any commercial space. However, the success of your hardwood floor installation depends on how well you prepare before laying the first plank. Proper preparation helps prevent common issues like warping, gaps, and uneven surfaces—ensuring your floors look great and last for years.

This guide will walk you through the key steps to prepare for a seamless hardwood flooring installation, from selecting the right type of wood to making sure the subfloor is in top condition.

1. Choosing the Right Hardwood Flooring

The first and most important step in preparing for hardwood flooring installation is selecting the right material. Not all hardwood floors are the same, and the type you choose will impact the look, durability, and performance of your flooring.

What are the best types of hardwood for commercial spaces?

Some hardwood species are better suited for high-traffic areas than others. Here are some of the most durable options:

Oak – A classic choice known for its strength and versatility. It’s available in red and white oak, both of which are great for commercial applications.
Maple – Harder than oak and commonly used in gymnasiums due to its resistance to heavy foot traffic.
Hickory – One of the hardest domestic wood species, hickory is excellent for commercial spaces that need extra durability.

Solid vs. Engineered Hardwood: Which one should you choose?

There are two main types of hardwood flooring: solid and engineered. The best option depends on your space, climate, and long-term maintenance needs.

Solid Hardwood
- Made from a single piece of wood.
- Can be sanded and refinished multiple times.
- Best for spaces where humidity and temperature don’t fluctuate much.
- Provides a traditional, high-end look.
Engineered Hardwood
- Made with a real hardwood veneer over layers of plywood.
- More resistant to moisture and humidity, making it ideal for Florida’s climate.
- Can only be refinished a few times, depending on the thickness of the top layer.
- Typically more affordable than solid hardwood.

Should you choose pre-finished or unfinished hardwood?

Your flooring finish plays a role in the installation timeline and final look.

Pre-finished Hardwood
- Comes sanded, stained, and sealed from the factory.
- Faster installation since no finishing is required on-site.
- More durable factory-applied finish.
- Limited color and customization options.
Unfinished Hardwood
- Requires sanding, staining, and finishing after installation.
- Allows for full customization to match other elements in the space.
- Takes longer to install but provides a seamless look.

2. Let the Wood Adjust to the Space

Before you install your hardwood flooring, the wood needs time to adjust to the conditions of the space where it will be placed. This process, known as acclimation, helps prevent problems like expansion, shrinking, and warping after installation.

Why is acclimation important?

Wood naturally absorbs and releases moisture based on the humidity and temperature of its surroundings. If planks are installed before they adjust to the environment, they can expand and push against each other or shrink and leave gaps.

How long does hardwood need to acclimate?

The general recommendation is to let the hardwood sit in the room for at least 72 hours before installation. However, for high-humidity areas, it’s best to allow five to seven days for acclimation.

How should you store the wood during acclimation?

To ensure proper acclimation:

Keep the flooring inside the installation area rather than in a garage or storage facility.
Lay the boxes flat on the floor, stacking them no more than three or four high.
Avoid placing planks directly on concrete—use a pallet or spacers to allow air circulation.
Maintain consistent temperature and humidity levels in the room.

3. Make Sure the Subfloor is Ready

Your subfloor is the foundation for your hardwood flooring. If it’s not in good shape, your hardwood installation could run into serious issues like uneven surfaces, creaking, or moisture damage.

What is a subfloor, and why does it matter?

A subfloor is the layer beneath your hardwood flooring. It’s usually made of plywood or concrete and provides support for the planks. If the subfloor isn’t prepared correctly, it can cause the hardwood to move, squeak, or develop gaps over time.

How do you check for leveling issues?

An uneven subfloor can lead to dips or raised areas in the hardwood. To check for issues:

Use a long level or straightedge to identify any high or low spots.
If you find high spots, sand them down with a floor sander.
If there are low spots, fill them with a self-leveling compound to create a flat surface.

How do you test for moisture in the subfloor?

Since moisture can cause hardwood floors to warp or buckle, it’s critical to check for excessive moisture before installation.

For wood subfloors, use a moisture meter to ensure levels are below 12%.
For concrete subfloors, perform a moisture test using a calcium chloride kit. Moisture should be below 3% before installing hardwood.
If moisture levels are too high, use a moisture barrier or vapor retarder before installation.

How should you clean the subfloor before installation?

Once the subfloor is level and dry, make sure it’s completely clean:

Sweep or vacuum up any dust, dirt, or debris.
Remove old nails, staples, or adhesive from previous flooring.
If necessary, install an underlayment to provide extra support and noise reduction.

Taking the time to prepare properly before installing hardwood flooring can save you from costly mistakes and repairs down the road. By choosing the right wood, allowing for acclimation, and ensuring a level, moisture-free subfloor, you’ll set your hardwood floors up for long-term success.

Step-by-Step Hardwood Floor Installation

Installing hardwood flooring is a rewarding project that adds warmth and durability to commercial spaces. While the process requires careful planning and attention to detail, following the right steps can ensure a smooth and long-lasting installation.

This guide will walk you through the step-by-step process of hardwood floor installation, from choosing the right method to adding the final touches. Whether you’re working with solid hardwood or engineered wood, these guidelines will help you achieve a professional-quality result.

1. Pick the Right Installation Method

Not all hardwood floors are installed the same way. The best installation method depends on the type of hardwood flooring you’ve chosen and the condition of the subfloor. Here’s a breakdown of the three main methods:

Nail-Down Installation

Best for solid hardwood floors.
Requires a wood subfloor for the nails or staples to grip.
Uses a flooring nailer or stapler to secure the planks in place.
Creates a strong, stable floor that can be refinished multiple times.
Takes longer than other methods but provides a traditional, long-lasting installation.

When should you use this method?
If you’re installing solid hardwood in a commercial space with a plywood subfloor, the nail-down method is the most reliable choice. However, it’s not ideal for concrete subfloors.

Glue-Down Installation

Commonly used for engineered hardwood but can work with some solid hardwoods.
Requires strong adhesive to bond planks directly to the subfloor.
Works well on both wood and concrete subfloors.
Provides a firm, stable floor with excellent sound reduction.
Requires precise application to avoid excess glue seeping between boards.

When should you use this method?
If you’re installing engineered hardwood or working with a concrete subfloor, glue-down installation is a good option. It’s often used in high-traffic areas where a stable and quiet floor is essential.

Floating Installation

Used exclusively for engineered hardwood and laminate flooring.
Planks click and lock together without nails or glue.
Sits on top of an underlayment, which provides cushioning and noise reduction.
Quick and easy installation compared to other methods.
Allows for expansion and contraction, making it ideal for humid environments.

When should you use this method?
Floating floors are great for commercial spaces that need a quick installation with minimal disruption. This method works well in rented spaces or areas where you may need to replace or remove the flooring in the future.

2. Plan the Layout

Before you start installing the planks, take some time to plan the layout. A well-thought-out layout ensures a balanced, natural-looking floor and prevents structural weaknesses.

Pick a Starting Point

Typically, flooring is installed parallel to the longest wall in the room.
In a commercial space, consider the main entrance or focal point—this is where the flooring direction should look the most natural.
If the room is irregularly shaped, a professional flooring installer may recommend a different approach.

Stagger the Planks for Strength and Aesthetic Appeal

Never line up the ends of the planks in a straight row—this creates weak points in the floor.
Planks should be staggered in a random pattern so the seams don’t form noticeable lines.
A good rule of thumb is to keep end joints at least 6 inches apart from one row to the next.
If using multiple box sets of flooring, mix the planks to create a more natural variation in color and grain pattern.

Check for Alignment and Expansion Gaps

Before securing any planks, lay out a test row to ensure the pieces fit well together.
Leave a ¼-inch expansion gap around the perimeter of the room to allow for natural wood movement.

3. Install the Hardwood Flooring

Now that you’ve planned the layout, it’s time to install the flooring. The process varies depending on the installation method you’ve chosen.

Nail-Down Installation

Start at one end of the room and lay the first row of planks with the tongue side facing the wall.
Use a flooring nailer to drive nails or staples through the tongue of each plank at a 45-degree angle.
Space nails about 6-8 inches apart to ensure a firm hold.
Continue row by row, using a tapping block and rubber mallet to lock the planks together.

Glue-Down Installation

Use a trowel to spread flooring adhesive in a thin, even layer across the subfloor.
Lay planks in place, pressing them firmly into the adhesive.
Work in small sections to avoid the glue drying too quickly.
Wipe away any excess adhesive before it dries.
Use weights or a floor roller to ensure the planks bond properly.

Floating Installation

Roll out the underlayment to provide cushioning and moisture protection.
Connect the planks by inserting the tongue side into the groove at an angle, then pressing down to lock them together.
Continue row by row, using spacers along the walls to maintain the expansion gap.
Trim the final row as needed to fit snugly against the wall.

4. Add the Finishing Touches

Once all the planks are in place, the installation is almost complete. A few final steps will give the floor a polished, professional look.

Install Trim and Molding

Baseboards, quarter-round molding, or transition strips help cover expansion gaps and create a clean finish.
If you removed existing baseboards, reattach them once the flooring is installed.
Use a nail gun or adhesive to secure molding in place, but avoid nailing into the hardwood floor itself.

Apply a Protective Finish (If Needed)

If you installed pre-finished flooring, no additional finish is required.
If you used unfinished hardwood, apply a stain and protective sealant to enhance durability and moisture resistance.

Let the Floor Settle Before Use

Avoid placing heavy furniture or foot traffic on the floor for at least 24 hours after installation.
If using a glue-down method, wait 48-72 hours before moving in furniture.
Keep indoor humidity levels consistent to allow the flooring to stabilize.

Hardwood floor installation takes time and precision, but when done correctly, it creates a beautiful and long-lasting floor that enhances any commercial space. Choosing the right installation method, planning the layout, and finishing the job with attention to detail are key to a successful project.

How to Take Care of Hardwood Floors

Hardwood floors are built to last, but they need regular maintenance to keep their beauty and durability. Daily foot traffic, dirt, spills, and environmental factors can all take a toll. With proper care, your floors will continue looking new for years to come.

How often should you clean hardwood floors?

Hardwood floors should be cleaned regularly to prevent dirt buildup and scratches. The best routine includes:

Daily – Sweep or dry mop to remove dust and dirt.
Weekly – Use a damp mop with a hardwood-friendly cleaner to remove deeper grime.
Monthly – Inspect for scratches and apply a wood-safe polish if needed.
Annually – Consider professional deep cleaning or refinishing if floors look dull or worn.

What’s the best way to clean hardwood floors?

Cleaning hardwood floors correctly helps prevent damage. Follow these steps:

Sweep or dust mop first – This removes loose dirt that can scratch the surface.
Use a hardwood-safe cleaner – Avoid harsh chemicals, vinegar, or steam cleaners, as they can damage the finish.
Damp mop (not soaking wet!) – Excess water can seep into the wood and cause warping. A microfiber mop slightly dampened with a hardwood cleaner is best.
Dry immediately – Any remaining moisture should be wiped up with a dry cloth to prevent damage.

How can you prevent scratches and dents?

Hardwood floors are tough, but they’re not indestructible. Taking these precautions can keep them in great shape:

Use felt pads under furniture – Heavy furniture can leave dents or scratches when moved. Adding felt pads to chair and table legs protects the wood.
Place rugs in high-traffic areas – Entryways, hallways, and commercial spaces with heavy foot traffic benefit from area rugs or mats.
Keep pet nails trimmed – If pets are allowed in the space, their nails can scratch the floor over time.
Avoid wearing high heels – Stiletto heels or damaged shoe soles can leave dents and scuffs.

Can humidity affect hardwood floors?

Yes! Hardwood is a natural material that expands and contracts based on humidity levels. Extreme changes can cause gaps, warping, or cracking.

To maintain a stable environment:

Keep indoor humidity between 30-50% year-round.
Use a humidifier in winter to prevent wood from drying out and shrinking.
Use a dehumidifier in summer to reduce excess moisture that can cause swelling.
Avoid exposing floors to direct sunlight for long periods, as UV rays can fade the finish.

Mistakes to Avoid When Installing Hardwood Floors

Even a high-quality hardwood floor can develop problems if installed incorrectly. Avoiding these common mistakes can save time, money, and frustration.

1. Skipping Acclimation

What happens if wood isn’t acclimated before installation?
Wood naturally absorbs and releases moisture. If it isn’t given time to adjust to the room’s humidity and temperature, it can expand or shrink after installation, leading to gaps, warping, or buckling.
