Gaps in New Hardwood? (1 Fix Prevents Disaster!)

You know, those little (or not-so-little) spaces that appear between your planks, seemingly out of nowhere?

Trust me, I’ve seen it all. From hairline cracks to canyons you could lose a sock in.

These gaps aren’t just an eyesore; they can be a sign of bigger problems brewing beneath the surface.

In this article, I’m going to walk you through why these gaps appear in new hardwood floors, what happens if you ignore them, and, most importantly, the one fix that can prevent a flooring disaster.

Think of this as your hardwood gap survival guide!

Let’s dive in!

Section 1: Understanding Hardwood Flooring

Okay, first things first. Let’s get on the same page about hardwood flooring.

It’s not just any wood nailed to the floor, you know?

There are two main types: solid hardwood and engineered hardwood.

• Solid Hardwood: This is the real deal – planks made from a single piece of wood. It’s durable, beautiful, and can be refinished multiple times. Think oak, maple, cherry, walnut… the classics.

• Engineered Hardwood: This is constructed with multiple layers of wood veneer glued together, with a top layer of solid hardwood. It’s more stable than solid hardwood, meaning it’s less prone to expansion and contraction.

  It’s also a bit more budget-friendly.

The installation process also matters.

Typically, hardwood is either nailed, stapled, or glued down to a subfloor (usually plywood or concrete).

The key here is acclimation.

This means letting the wood sit in your home for several days before installation so it can adjust to the temperature and humidity levels.

I can’t stress this enough: skipping this step is a recipe for disaster!

Now, here’s the thing about wood: it’s a natural material.

It breathes. It moves. It reacts to its environment.

Just like your skin gets dry in the winter, wood expands and contracts with changes in temperature and humidity.

When the air is humid, wood absorbs moisture and swells.

When the air is dry, wood loses moisture and shrinks.

Section 2: Identifying the Causes of Gaps

Alright, let’s get detective hats on and figure out why those gaps are showing up.

It’s usually a combination of factors, but here are the most common culprits:

• Environmental Factors: This is the big one. As I mentioned, humidity and temperature fluctuations can wreak havoc on hardwood.

  Think about it: in the winter, your heating system dries out the air, causing the wood to shrink and gaps to appear.

  Then, in the summer, the humidity rises, and the wood expands, potentially closing those gaps (or even causing buckling, yikes!).

  According to the EPA, ideal indoor humidity levels should be between 30-50%. EPA Indoor Air Quality

• Installation Issues: This is where things can get tricky. If the wood wasn’t properly acclimated before installation, it’s going to move a lot after it’s nailed down.

  Also, if the installer didn’t leave enough space between the planks during installation (a small expansion gap), the wood won’t have room to expand, leading to pressure and potential gaps down the road.

  Subfloor prep is also crucial. A uneven or unstable subfloor can cause the hardwood to shift and gaps to form.

• Wood Quality and Type: Not all wood is created equal. Some species are more stable than others.

  For example, maple and birch are known to be more susceptible to expansion and contraction than oak or walnut.

  Also, the quality of the wood itself matters. Cheaper, lower-grade wood may be more prone to warping and cracking, leading to gaps.

  Engineered hardwood is generally more stable than solid hardwood because of its layered construction.

  This makes it a better choice for areas with high humidity or temperature fluctuations.

  However, even engineered hardwood can experience gaps if not installed properly.

Section 3: The Risks of Ignoring Gaps

Okay, so you’ve got gaps. Big deal, right? Wrong.

Ignoring those gaps can lead to some serious problems down the line.

Here’s why you need to address them:

• Aesthetic Impact: Let’s be honest, gaps just don’t look good. They can make your beautiful hardwood floor look cheap and neglected.

  It detracts from the overall aesthetic of your home and can be a real eyesore.

• Structural Concerns: This is where it gets serious. Gaps can allow moisture to seep down into the subfloor, leading to mold growth, rot, and structural damage.

  They can also create a breeding ground for pests like insects and rodents.

  Over time, gaps can weaken the floor, making it more prone to squeaking, shifting, and even buckling.

• Resale Value: If you’re planning to sell your home, gaps in your hardwood floor can be a major turnoff for potential buyers.

  It can give the impression that the home is poorly maintained and may even lead to lower offers.

  Buyers may also be concerned about the potential for hidden damage, such as mold or rot.

  According to a survey by the National Association of Realtors, hardwood floors are a highly desirable feature for homebuyers. NAR Home Features

  So, keeping your floors in good condition is essential for maximizing your home’s resale value.

Section 4: The One Fix That Prevents Disaster

Alright, let’s get to the good stuff: how to fix those gaps!

Now, there are a few different approaches you can take, but the most effective and long-lasting solution is to use wood filler.

Here’s a step-by-step guide:

1. Identify the Type of Gap: Before you start filling, it’s important to determine whether the gap is seasonal or permanent.

   Seasonal gaps are those that appear and disappear with changes in humidity.

   Permanent gaps are those that remain year-round.

   If the gaps are seasonal, it’s best to wait until the dry season (usually winter) to fill them, as the wood will be at its most contracted state.

   This will prevent the filler from being pushed out when the wood expands in the summer.

2. Gather Necessary Tools and Materials: You’ll need the following:

   • Wood filler (choose a color that matches your hardwood)
   • Putty knife
   • Sandpaper (120-grit and 220-grit)
   • Vacuum cleaner
   • Soft cloth
   • Painter’s tape (optional)

3. Step-by-Step Repair Process:

   • Preparation: Start by thoroughly cleaning the area around the gap. Vacuum up any dust, dirt, or debris.

     If necessary, use a damp cloth to wipe down the area, but make sure it’s completely dry before proceeding.

     You can also use painter’s tape to protect the surrounding wood from getting stained by the filler.

   • Application: Using the putty knife, scoop up a small amount of wood filler and apply it to the gap.

     Press the filler firmly into the gap, making sure to fill it completely.

     Overfill the gap slightly, as the filler will shrink as it dries.

     I like to work in small sections, filling a few inches at a time.

     This gives me more control and prevents the filler from drying out too quickly.

   • Smoothing: Once the gap is filled, use the putty knife to smooth the surface of the filler.

     Remove any excess filler and try to blend it seamlessly with the surrounding wood.

     If you’re using painter’s tape, carefully remove it at this point.

   • Drying: Allow the filler to dry completely according to the manufacturer’s instructions.

     This usually takes several hours or even overnight.

     Avoid walking on the filled area while it’s drying.

   • Sanding: Once the filler is dry, use 120-grit sandpaper to sand down any excess filler and smooth the surface.

     Be careful not to sand too hard, as you could damage the surrounding wood.

     Switch to 220-grit sandpaper for a final, smooth finish.

   • Cleaning: Vacuum up any sanding dust and wipe down the area with a soft cloth.

   • Finishing Touches: If desired, you can apply a sealant or finish to the filled area to protect it and blend it in with the surrounding wood.

     Choose a sealant or finish that is compatible with your hardwood floor.

     I usually recommend using a water-based polyurethane finish for durability and ease of application.

4. Prevention Tips Post-Fix: Once you’ve filled the gaps, it’s important to take steps to prevent them from reappearing.

   • Maintain Consistent Humidity: Use a humidifier in the winter to keep the air from getting too dry.

     Aim for a humidity level of 30-50%.

     You can also use a dehumidifier in the summer to remove excess moisture from the air.

   • Control Temperature: Avoid extreme temperature fluctuations in your home.

     Keep the thermostat set at a consistent temperature, especially during the heating and cooling seasons.

   • Use Area Rugs: Place area rugs in high-traffic areas to protect the hardwood floor from wear and tear.

     Rugs can also help to insulate the floor and reduce temperature fluctuations.

   • Clean Regularly: Sweep or vacuum your hardwood floor regularly to remove dust, dirt, and debris.

     Avoid using harsh chemicals or abrasive cleaners, as they can damage the finish.

     I recommend using a hardwood floor cleaner specifically designed for your type of floor.

Section 5: When to Call a Professional

Okay, so you’ve tried the wood filler trick, but the gaps are still there, or they’re just too big to handle.

When is it time to call in the pros?

Here are a few signs that the problem may be beyond a simple DIY fix:

• Large or Numerous Gaps: If you have a lot of gaps, or if the gaps are very wide (more than 1/8 inch), it may be a sign of a more serious problem, such as subfloor issues or structural damage.

• Buckling or Warping: If your hardwood floor is buckling or warping, it’s a sign that there’s excessive moisture or humidity.

  This can be a difficult problem to fix and may require professional intervention.

• Mold or Rot: If you suspect that there’s mold or rot beneath your hardwood floor, it’s important to call a professional immediately.

  Mold and rot can be hazardous to your health and can cause serious structural damage.

• Warranty Concerns: If your hardwood floor is still under warranty, it’s important to check the terms of the warranty before attempting any DIY repairs.

  Some warranties may be voided if you perform unauthorized repairs.

Hiring a professional flooring contractor has several benefits:

• Expertise: Professionals have the knowledge and experience to diagnose the problem and recommend the best solution.

• Tools and Equipment: Professionals have access to specialized tools and equipment that can make the repair process faster and more efficient.

• Warranty: Many professional flooring contractors offer warranties on their work, giving you peace of mind.

When choosing a flooring contractor, be sure to:

• Get Referrals: Ask friends, family, or neighbors for recommendations.
• Check Reviews: Read online reviews to see what other customers have to say.
• Get Multiple Bids: Get bids from at least three different contractors to compare prices and services.
• Check Licensing and Insurance: Make sure the contractor is licensed and insured.
• Get a Written Contract: Make sure the contract includes a detailed description of the work to be performed, the materials to be used, and the total cost.
