Have you just had your hardwood floor installed and now you’re wondering why it squeaks whenever you walk on it? These mysterious sounds coming from your newly installed hardwood floor can be perplexing, unsettling, and downright annoying. Especially if you’ve invested a considerable amount of time and money into installing a beautiful hardwood floor. But don’t despair, it’s a more common issue than you’d realize and one that can be alleviated with a bit of knowledge and a few fixes.

At California Flooring and Design, we understand how frustrating it can be when your newly installed hardwood floor squeaks. The sound can disrupt the tranquility of your home and leave you questioning the quality of your floor or even the installation process. Is it an issue with the wood itself? Or could it be an installation error? Understanding the root cause of these noises is key to addressing the issue.

While there may not be a one-size-fits-all solution, it is often a combination of a few factors at play, such as seasonal changes causing the wood to expand and contract, loose subflooring, or boards rubbing against each other or sliding against nail shafts.

Here’s a brief breakdown of potential reasons for that irritating squeak:

  1. Seasonal changes causing the wood to expand and contract

Understanding Why Hardwood Floors Squeak

You might be wondering, “why does my newly installed hardwood floor squeak?” The main culprit behind your squeaky floor is movement. Now, you might wonder how your stationary floor could possibly move. Well, floors don’t move on their own. It’s the act of being stepped on that causes subtle shifts and movements. These movements, as minor as they may be, are what lead to those annoying squeaks you hear every time you walk across the room.

The Role of Movement in Squeaking Floors

In a perfectly installed hardwood floor, all elements are tightly secured together, leaving no room for movement. However, if there are any loose boards, gaps, or voids, these areas can move when stepped on, rubbing against each other or the nails holding them down. This friction creates the squeaky noise you hear. It’s like a tiny violin being played under your feet every time you walk around.

The Impact of Temperature and Humidity on Wood Floors

Another significant factor that can cause your newly installed hardwood floor to squeak is moisture. Wood is a hygroscopic material, which means it can absorb and release moisture from the surrounding environment. As the moisture content in the wood changes, it can lead to swelling or shrinking of the wood planks. This change in size can result in gaps between the planks or cause the planks to rub against each other, causing those irritating squeaks.

Maintaining consistent relative humidity levels in your home is crucial to minimizing these moisture-induced movements in your hardwood floors. At California Flooring and Design, we understand the importance of this and can guide you on the best practices to maintain optimal moisture levels in your home.

The Effect of Home Settling on Wood Floors

Over time, your home will naturally settle due to a variety of factors like changes in soil conditions and load-bearing. This settling can lead to shifts in the subfloor level, creating voids beneath your hardwood floor. These voids can allow parts of the floor to move when stepped on, leading to squeaks.

To completely avoid squeaks, it’s important to eliminate any movement in the wood floor. During installation, our team at California Flooring and Design ensures that the subfloor is perfectly level and that there are no voids that could lead to movement and subsequent squeaks.

Now that we’ve unraveled the mystery behind why your hardwood floors squeak, let’s look at common causes and how to fix these in the following sections.

Common Causes of Squeaky Hardwood Floors

We’ve established that movement is the main culprit behind your newly installed hardwood floor squeaks. But what triggers this movement? Let’s break it down into three common causes: subfloor level and joist spacing, moisture, and the fit of the tongue and groove.

The Influence of Subfloor Level and Joist Spacing

The subfloor is the foundation for your hardwood flooring. If it’s not level or has voids, it can lead to movement in the wood floor, resulting in that annoying squeak. This could be caused by construction residue on the subfloor, uneven seams, or joists that are out of level. Other factors include settling in the home and heaving beams. To avoid squeaks, ensure a perfectly level subfloor and proper joist spacing during installation.

The Effect of Moisture on Floor Movement

Moisture plays a significant role in the movement of your floors. Wood, being a natural material, responds to changes in humidity levels by expanding and contracting. This is referred to as seasonal movement. If the moisture content in the wood isn’t consistent year-round, the fit of the tongue and groove may change, leading to floor movement and squeaks. Thus, maintaining a consistent moisture level is crucial. This can be achieved by installing a humidifier on your furnace unit, running a portable humidifier, or even by hanging damp clothes around the house to dry.

The Role of Tongue and Groove Fit in Squeaking Floors

The tongue and groove of your hardwood flooring are designed to fit together snugly to allow for blind nailing and easy installation. However, changes in the moisture content of the flooring can affect the fit of the tongue and groove. If the flooring becomes drier, the tongue and groove will be looser. Conversely, if the flooring’s moisture content increases, the fit becomes tighter. This change can lead to movement in the flooring, causing it to squeak.

At California Flooring and Design, we understand the frustration that comes with squeaky hardwood floors. Our team of experts is committed to ensuring a smooth and squeak-free installation process, taking into account all the factors that may cause your floor to squeak. In the next section, we’ll discuss practical solutions to prevent and fix squeaky hardwood floors. So, stick around to ensure that your hardwood flooring experience is as seamless and satisfying as possible.

How to Prevent and Fix Squeaky Hardwood Floors

After understanding the common causes of squeaky floors, let’s turn our focus to prevention and fixes. The goal here is to maintain your newly installed hardwood floor squeaks-free and prolong its lifespan.

Maintaining Consistent Moisture Levels

One of the most effective ways to prevent floor squeaking is by maintaining consistent moisture levels in your home. As we’ve learned, moisture can cause wood to expand and contract, leading to movement that results in squeaks. This movement can be minimized by keeping the moisture content in the wood consistent year-round.

Most homes have central air, which helps control indoor humidity. However, if your home is susceptible to humidity change, consider having a humidifier installed on your furnace unit. This introduces moisture into your home’s forced air system, which the furnace then distributes evenly throughout your home. This can prevent the hardwood floor from absorbing and releasing moisture, thereby reducing the chances of squeaks.

Other methods of maintaining consistent moisture levels include running a portable humidifier, drying damp clothes in the house, or boiling water on the stove.

Addressing Voids in the Subfloor

A squeak-free floor starts from the bottom up. This means the subfloor, the structural base for your hardwood floor, plays a critical role. Void spaces in the subfloor can cause parts of your flooring to be suspended, leading to movement and squeaks when stepped on.

Common causes of voids in your subfloor can be construction residue (like drywall mud or adhesive), high or low areas in the subfloor seams, out-of-level joists, or settling in the home.

To address these issues, ensure that your subfloor is clean, flat, and level before installing the hardwood floor. If the subfloor isn’t perfectly flat, consider sanding the seams of the plywood flat. Fill any voids and you’ll eliminate movement and, as a result, eliminate squeaks.

Lubricating Friction Points and Filling Hollow Spots

Sometimes, the movement causing your floor to squeak is due to friction between the flooring boards. In such cases, lubricating the friction points can effectively eliminate the sound. A commonly used lubricant for this purpose is powdered graphite, which reduces friction and extends the lifespan of your hardwood floors.

Another method involves the use of hollow spot fillers. If your floor is having trouble being suspended, hollow spot fillers can be quite effective in stabilizing the floor and preventing squeaks.

Preventing and fixing squeaky hardwood floors is a continuous process that involves maintaining consistent moisture levels, addressing voids in the subfloor, and lubricating friction points. By following these steps, you’ll not only enjoy a quiet and peaceful home, but you’ll also preserve the beauty and structural integrity of your hardwood floors.

In the next section, we’ll examine a case study of a homeowner who experienced squeaky engineered maple wood floors, and we’ll discuss the troubleshooting process they undertook.

Case Study: Troubleshooting a Squeaky Engineered Maple Wood Floor

Identifying the Problem: Pops, Crackles, and Squeaks

When a homeowner installed a beautiful engineered maple wood floor in their 7-year-old house, they were initially thrilled with the results. However, a few days after the installation, they began to hear pops and crackles when they walked on the floor. Once a spot was stepped on, it seemed as if the board “popped” into place and the sound didn’t recur in that exact spot until hours later. Over time, some of these pops evolved into full-blown squeaks, creating a symphony of sounds that was far from harmonious.

Investigating Potential Causes: Product or Installation Issue?

The homeowner was stumped. Their house was relatively new, and their previous floor had made no noise. They had followed the recommended procedure for the installation, including acclimating the wood for a week before the installation and using tar paper. In their mind, this pointed to either a product problem or an installation problem. But how could they be sure?

To uncover the cause of the problem, it’s crucial to gather as much information as possible. For example, it would be helpful to know how the floor was anchored (staples, cleats, or adhesive), the full thickness of the flooring, the number of ply, the moisture content of the subfloor and flooring, and the average humidity of the area. Also, any visible movement in the floorboards where there are squeaks could provide valuable clues.

Seeking Solutions: From Fastener Length to Installation Method

Based on their observations and the available information, the homeowner and their installer could explore potential solutions. If the installer used staples and there was excessive “walking out” of the newly installed flooring, this could indicate that the tongues of the floorboards were split during installation. In such a case, the solution might involve replacing the affected boards.

If the floor was a floating, click-lock system, the popping and squeaking could be due to the floor’s inherent characteristics. In this scenario, checking whether there was a foam used under the flooring could provide further insight.

However, without a professional evaluation, it’s challenging to pinpoint the exact cause and solution. That’s why at California Flooring and Design, we recommend calling in professional help when your newly installed hardwood floor squeaks. We have the experience and knowledge to diagnose and fix the problem efficiently, ensuring your floors are as silent as they are stunning.

The Role of Professional Evaluation and Repair in Fixing Squeaky Floors

While some minor squeaks can be addressed with do-it-yourself methods, there are times when it’s best to call in professionals. Here’s why.

When to Call a Professional

If your floor squeaks persistently or if the noise is accompanied by noticeable movement in the floorboards, it’s time to call a professional. It’s also advisable to seek professional assistance if you’ve tried DIY methods and the squeaking hasn’t stopped, or if the squeaking is widespread across large areas of the floor. As a homeowner, you might not have the tools or expertise necessary to diagnose and fix the issue without potentially causing further damage.

At California Flooring and Design, we have a team of seasoned professionals who can assess your situation and provide an effective solution.
