How to Fix Void Under Vinyl Plank Flooring? [Quick Fix Guide]

---

I’ve been in the flooring business long enough to know that issues can pop up at any moment, and one that comes up frequently is the void under vinyl plank flooring. It’s frustrating for both contractors and homeowners. A void can lead to all sorts of problems, including creaking, uneven surfaces, and even premature wear. Fortunately, there are effective solutions to tackle this issue head-on.

Identifying the Problem

When I first started installing vinyl plank flooring, I didn’t think much about what lay beneath it. I focused on aesthetics and installation techniques. But over time, I learned that one of the biggest challenges is ensuring a solid subfloor. If there’s a void, it’s like building on sand; things will shift, crack, and break down.

During a recent project in a client’s living room, I faced this exact issue. After laying down the planks, I noticed an unsettling bounce when walking across the floor. A quick inspection revealed a significant void underneath. It was a wake-up call for me, reminding me how crucial proper preparation is.

Causes of Voids

So, what causes these voids? In my experience, they can arise from several factors:

1. Moisture: If the subfloor wasn’t properly dried or sealed, moisture can lead to warping and create gaps.
2. Improper Installation: Sometimes, the underlayment isn’t laid down correctly or is of poor quality.
3. Old Flooring Removal: When removing old flooring, it’s easy to overlook debris and imperfections that might create voids.

Understanding these causes helped me realize how important it is to address them before beginning any installation.

Assessing the Damage

Before I could fix the problem, I needed to assess the extent of the damage. This involved:

• Tapping on the flooring in various spots to identify hollow sounds.
• Checking for movement when applying weight.
• Inspecting visible edges for gaps.

In my case, I’d say about 15% of the area had noticeable voids. It was clear that I couldn’t leave it as is.

Filling the Void: Step-by-Step Guide

Once I identified the voids, it was time to fill them. Here’s how I approached it:

1. Remove the Planks

First off, I carefully removed the affected vinyl planks. This step requires patience, especially if you want to reuse them later. Using a utility knife, I scored the edges and gently pried them up. If you’re doing this at home, take your time to avoid damaging the planks as you’ll want to reinstall them later if possible.

2. Inspect the Subfloor

With the planks out of the way, I was able to inspect the subfloor thoroughly. I found some areas where moisture had caused slight damage. In situations like this, it’s best to address any underlying issues before moving forward.

You want to look for signs of rot or mold, both of which can create long-term problems if left untreated. If you find any damaged areas, you may need to replace sections of the subfloor before proceeding.

3. Fill the Voids

For filling voids, I typically use a self-leveling compound or a floor patch product. Here’s how I apply it:

• Preparation: I cleaned the area thoroughly and made sure it was dry.
• Mixing: Following the manufacturer’s instructions, I mixed the compound until it reached a smooth consistency.
• Application: Using a trowel, I spread the compound over the voids. It’s crucial to feather the edges for a smooth transition with the surrounding area.

If you’re wondering how much compound you’ll need, a general rule is that one bag of self-leveling compound will cover about 40 square feet at a thickness of 1/8 inch. Adjust your calculations based on how deep the voids are.

4. Allow Drying Time

Patience is key here. I always let the compound dry completely, usually around 24 hours. During this time, I’m careful not to disturb it. If you’re in a rush, it might be tempting to speed up this process with fans or heaters, but this can lead to cracks in the compound.

5. Reinstall Vinyl Planks

Once everything is dry and level, I reinstalled the vinyl planks. This can be tricky if you’re reusing them since they might have lost their adhesive properties or locking mechanisms.

To help with this process:

• Check for any damage on the planks before reinstalling.
• Use an appropriate adhesive if needed.
• Ensure that all edges are aligned properly for a seamless look.

Successes and Challenges

Throughout my career, I’ve encountered various successes and challenges when filling voids under vinyl plank flooring.

Success Stories

One of my most memorable projects involved an upscale home where the homeowner had opted for luxury vinyl planks in her kitchen. After addressing multiple voids beneath her original flooring, she was thrilled with how solid everything felt afterward. It transformed her space completely!

Another successful project was in a bustling office space where we had to address multiple areas suffering from voids due to foot traffic over time. After repairs, not only did we improve aesthetics but also functionality—employees commented on how much quieter and sturdier the floors felt.

Challenges Faced

However, not every job went smoothly. There was a time when I underestimated the drying time of a self-leveling compound. After reinstalling the planks too soon, they began to shift again. This taught me to always err on the side of caution and double-check everything before proceeding.

I’ve also faced challenges with clients who wanted quick fixes without understanding the underlying issues. For instance, rushing through repairs may seem tempting but often leads to more problems down the road.

Cost Estimation and Budgeting

Cost is always a consideration in flooring projects. When working through estimates with clients, I often rely on FloorTally to help streamline this process. The platform pulls local material and labor rates, giving me accurate cost projections right from the start.

For example, when filling voids under vinyl plank flooring, costs can vary significantly based on:

• Material used: Self-leveling compounds can range from $15 to $50 per bag.
• Labor costs: Depending on your location, labor might be anywhere from $50 to $100 per hour.
• Extent of repairs: If extensive damage is found upon inspection, additional materials and labor may be required.

Using FloorTally allows me to create realistic budgets that clients appreciate for their transparency.

Sample Cost Breakdown

Here’s a rough breakdown based on my recent projects:

• Self-Leveling Compound (3 bags): $120 (assuming $40 per bag)
• Labor (4 hours): $300 (at $75 per hour)
• Miscellaneous Supplies: $50 (trowels, utility knives, etc.)

Total Estimated Cost: $470

This estimate helps clients understand what they’re getting into financially and sets clear expectations.

Comparing Different Approaches

I’ve tried various approaches to filling voids under vinyl plank flooring over the years:

Self-Leveling Compound vs. Floor Patch Products

Self-Leveling Compound

• Pros: Great for larger areas; creates an even surface.
• Cons: Can be more expensive; requires more drying time.

Self-leveling compounds are often my go-to for larger voids because they provide a smooth finish that’s easy to work with during installation.

Floor Patch Products

• Pros: Easier for smaller patches; typically cheaper.
• Cons: Not always suitable for large voids; might need multiple applications.

For smaller areas or quick fixes, floor patch products come in handy. They usually dry faster but may require more effort if you have several spots to address.

Based on my experiences, if you’re dealing with widespread issues, self-leveling compounds are often worth the investment for their efficiency and effectiveness.

Practical Tips for Homeowners

If you’re considering tackling this issue yourself or working with a contractor, here are some helpful tips:

1. Always Inspect Before Installation: Don’t skip this step! It saves time and money in the long run.
2. Use Quality Materials: Invest in good underlayment and subfloor materials; they make all the difference.
3. Patience is Key: Rushing through drying times can lead to future headaches.
4. Don’t Hesitate to Seek Help: If you’re unsure about any step, consulting with an experienced contractor is wise.
5. Document Everything: Keep records of materials used and conditions found during installation; this helps in future repairs or evaluations.

Maintenance After Repair

Once you’ve successfully filled the voids and reinstalled your vinyl plank flooring, maintenance becomes crucial to prevent future problems:

• Regular Inspections: Check for any movement or creaking periodically.
• Control Moisture Levels: Keeping humidity in check with dehumidifiers if necessary makes a difference.
• Proper Cleaning Techniques: Avoid excessive water when cleaning; it can seep into seams and cause issues down the line.

Additionally, consider placing area rugs in high-traffic zones to reduce wear on your vinyl planks and keep them looking fresh longer.

Real-Life Examples

Let me share some real-life scenarios where filling voids made a significant impact:

Case Study: Residential Living Room

In one particular residential job, I was called to fix a living room where children constantly played basketball indoors—definitely not recommended! The vinyl planks were shifting due to movement beneath them caused by voids underneath from improper installation years back.

After removing the planks and assessing for moisture damage (which thankfully wasn’t present), I filled about 20 square feet worth of voids using self-leveling compound before reinstalling everything tightly together. The result? A sturdy floor that could withstand more playtime without sounding like it would collapse!

Case Study: Commercial Space

Another project involved a small café where patrons noticed creaks every time someone walked across certain sections of the floor—an undesirable situation for any business! Upon inspection, we found extensive voids due primarily to old flooring that hadn’t been adequately removed or addressed previously.

With careful planning using FloorTally for accurate budgeting (which helped us stay within tight margins), we managed to fill these voids quickly yet effectively using a combination of self-leveling compounds followed by new vinyl planks specifically designed for high foot traffic areas.

Conclusion

Filling voids under vinyl plank flooring isn’t just about fixing an immediate problem; it’s about ensuring longevity and stability for your flooring investment. Whether you choose to handle it yourself or bring in a professional like me, understanding the process can make all the difference.

Remember that every project has its unique challenges and victories. By staying informed and prepared, you can navigate these situations with confidence and keep your floors looking great for years to come!
