Planning to install laminate flooring yourself? I’ll show you exactly what mistakes to avoid so your project turns out perfect. I’ve installed laminate in five different rooms. Made every mistake in the book. My first floor buckled within three months.
But I learned from each disaster.
In this guide, you’ll learn about the 17 most common laminate flooring mistakes that can ruin your project. I’ll share what went wrong in my installations and how to fix each problem before it starts.
Trust me on this. I’ve wasted hundreds of dollars and countless hours fixing these exact mistakes. You don’t have to repeat my errors.
This article will save you time, money, and frustration. Your laminate floor will look professional and last for years when you avoid these costly mistakes.
Why Small Mistakes Can Cost Big in Laminate Flooring
You might think a small error won’t matter much. But laminate flooring is unforgiving. One tiny mistake can ruin the entire project. Your floor could buckle, gap, or wear out years too early.
I learned this lesson when my kitchen floor started lifting after just three months. The repair cost more than hiring a pro from the start.
Don’t make my mistakes. Let me walk you through the biggest ones.
1. Failing to Leave Clearance Around Fixed Objects
I installed my planks right up against the toilet base. No gap at all. Three weeks later, the planks were buckling.
Laminate expands and contracts with temperature changes. If you don’t leave space around fixed objects, the planks have nowhere to go.
What to do:
- Leave quarter-inch gaps around toilets, cabinets, and vents
- Cover gaps with trim or caulk later
- Use spacers to keep gaps consistent
2. Skipping Subfloor Preparation
I thought my old hardwood subfloor was fine. But laminate shows every imperfection. Every squeak. Every tiny bump.
Your subfloor needs to be perfect before you start.
Check for these issues:
- Squeaky spots and secure them
- High or low spots and level them
- Loose boards and tighten them
- Dirt and debris and clean everything
3. Forgetting to Acclimate the Laminate
I brought my laminate home and started installing right away. Big mistake. The planks expanded after installation because they weren’t used to my home’s temperature.
Laminate needs time to adjust to your home’s conditions.
Steps to follow:
- Store planks in the installation room
- Wait 48 hours minimum
- Keep boxes sealed until ready
- Maintain normal room temperature
4. Not Using an Underlayment
I skipped underlayment to save money. The floor felt hollow and every footstep echoed through the house.
Underlayment is worth the extra cost.
Benefits include:
- Reduces noise significantly
- Creates moisture barrier
- Smooths minor subfloor problems
- Costs about 50 cents per square foot
5. Ignoring Expansion Gaps
I made tiny gaps thinking baseboards would hide them. When summer hit, my floor buckled in the middle of the room.
You need quarter-inch gaps around the entire room.
Remember to:
- Use spacers for consistent gaps
- Remove spacers after installation
- Reinstall baseboards to cover gaps
- Never skip this step
6. Poor Plank Alignment and Pattern Planning
I started in one corner without planning. Halfway through, my last row was less than two inches wide. Those skinny planks looked terrible.
Five minutes of planning saves hours of work.
Planning steps:
- Measure room width first
- Divide by plank width
- Adjust starting point accordingly
- Make end planks at least half-width
7. Cutting Planks Incorrectly
I used whatever saw was handy. The cuts were rough and the planks didn’t fit right.
Use the right tool for each cut.
Cutting tips:
- Use miter saw for crosscuts
- Use table saw for rip cuts
- Score front with utility knife first
- Cut from back to prevent chipping
8. Failing to Check for Moisture Issues
I installed laminate in a basement without checking the humidity. Within six months, planks were warping.
Moisture is laminate’s biggest enemy.
Check for these problems:
- Use moisture meter on subfloor
- Look for leaks around plumbing
- Check for water stains or odors
- Fix moisture issues first
9. Not Measuring Twice Before Cutting
I wasted countless planks by cutting them wrong. Each mistake cost me time and money.
Always double-check measurements.
Measuring rules:
- Mark cut lines clearly
- Hold plank in place to verify fit
- Cut slightly long when in doubt
- You can trim more but can’t add back
10. Installing in the Wrong Room Conditions
I installed it on a 90-degree day with no air conditioning. The planks shrank when the house cooled down.
Maintain normal conditions during installation.
Ideal conditions:
- Temperature between 65-75°F
- Humidity between 30-50%
- Good ventilation throughout
- Avoid extreme weather days
11. Forgetting to Mix Planks from Multiple Boxes
I used one box at a time. The color variations created obvious lines across my floor.
Mix planks for a natural look.
Mixing tips:
- Open several boxes at once
- Pull planks from different boxes
- Creates random natural pattern
- Extra work but better results
12. Overlooking Doorway and Transition Strips
I tried to run planks through doorways without transition strips. The joints lined up poorly and looked unprofessional.
Doorways need special attention.
Transition options:
- T-molding between laminate rooms
- Reducers for height differences
- End caps at sliding doors
- Threshold strips at exterior doors
13. Laying Planks in the Wrong Direction
I laid planks parallel to the longest wall. But the window light highlighted every joint badly.
Direction affects the final look.
Direction guidelines:
- Run toward main light source
- Follow longest wall in narrow rooms
- Consider traffic flow patterns
- Visualize the finished result first
14. Using the Wrong Tools or Low-Quality Materials
I tried using a regular hammer instead of a tapping block. I dented several planks and couldn’t get tight joints.
Good tools make better results.
Essential tools:
- Tapping block and pull bar
- Spacers for expansion gaps
- Quality saw for clean cuts
- Knee pads for comfort
15. Hammering Planks Directly
I hit planks directly with a hammer and dented the surface trying to close gaps.
Never hammer planks directly.
Proper technique:
- Always use tapping block
- Distributes force evenly
- Protects plank surface
- Use pull bar for end joints
16. Rushing the Installation
I tried to finish my living room in one weekend. The rushed work showed everywhere. Uneven gaps. Poor cuts.
Patience pays off with laminate.
Take time for:
- Careful layout planning
- Accurate cutting
- Checking each row
- Fixing problems immediately
17. Neglecting Post-Installation Care
I walked on my new floor immediately and moved furniture back the same day. Some joints separated.
Your job isn’t done when the last plank goes down.
Post-installation steps:
- Wait 24 hours before heavy traffic
- Use furniture pads when moving items
- Clean up all debris
- Reinstall trim properly

Frequently Asked Questions
Can I install laminate flooring over existing hardwood?
Yes, you can install laminate over hardwood if it’s level and secure. Just make sure the old floor isn’t squeaky and check that your room height can handle the extra thickness.
How long should I wait before walking on new laminate flooring?
Wait at least 24 hours before normal foot traffic and 48 hours before moving heavy furniture back. This gives the planks time to settle and the joints to lock properly.
Do I really need to leave expansion gaps if my room is small?
Absolutely yes, even in small rooms like bathrooms or closets. Laminate expands and contracts regardless of room size, and skipping gaps will cause buckling problems later.
What happens if I accidentally get water on my laminate floor during installation?
Wipe up water immediately with a dry cloth and make sure the subfloor is completely dry before continuing. Small spills won’t hurt, but standing water can seep into joints and cause swelling.
Can I save money by skipping the underlayment if my subfloor is perfect?
Never skip underlayment unless your laminate has it pre-attached. Even perfect subfloors need the moisture protection and sound dampening that quality underlayment provides.
