Choosing wood flooring isn’t just about picking a colour or finish—the way it’s installed plays a big role too. Two popular options are tongue and groove flooring and click-lock flooring. They both create a secure fit, but the way they work is different. Let’s break it down.
Is Tongue and Groove the Same as Click?
Not quite. While both connect planks together, they use different methods.
Tongue and groove flooring has a raised “tongue” on one edge of the plank that slots into a matching “groove” on the next. This creates a snug fit and is usually secured with nails, glue, or both.
Click-lock flooring is designed with a more modern interlocking system. Planks snap together with a simple push, forming a floating floor without glue or nails. It’s quick to install and often favoured by DIYers.
Which Type of Wooden Flooring Is Best?
That depends on what you need.
-
Looking for a sturdy, long-term fit? Tongue and groove is the better choice. Once installed, it feels solid underfoot and has a seamless look.
-
Need something quick and easy to install? Click-lock flooring is designed for convenience. The boards snap together effortlessly, so you don’t need professional tools or adhesives.
-
Fitting out a large space? T&G holds up well over time, especially in open-plan areas.
-
Want flexibility? Click-lock can be removed and reinstalled, making it a good option for rented properties or temporary flooring solutions.
It all comes down to what works best for your space and lifestyle.
What Are the Disadvantages of Click Lock Flooring?
Click-lock flooring has plenty of benefits, but there are a few drawbacks:
-
More movement – Since it floats above the subfloor rather than being fixed in place, it can shift slightly underfoot over time.
-
Not the best for moisture – If water gets between the planks, the locking mechanism can weaken, leading to separation.
-
Replacing damaged planks can be tricky – If one board is damaged, you may need to unlock several to reach and replace it.
For high-traffic or moisture-prone areas, it’s worth thinking about whether a fixed installation might be better.
What Are the Disadvantages of Tongue and Groove?
While tongue and groove flooring is known for its strength, there are a few downsides:
-
Takes longer to install – Since it needs glue or nails, installation is more involved compared to click-lock.
-
Repairs aren’t as simple – Replacing a damaged plank requires cutting it out, which can be more difficult than unlocking and swapping a click-lock board.
-
Expansion and contraction – Natural wood movement means that if it’s not fitted properly, gaps or buckling can develop over time.
If you’re looking for something that’s easy to install and adjust later, click-lock might be a better fit.
What Is the Strongest Type of Flooring?
If durability is the top priority, here’s what to look at:
-
Solid Hardwood – Classic, tough, and long-lasting. With proper care, it can last for generations.
-
Engineered Wood – Designed to handle humidity changes better than solid wood, reducing the risk of warping.
-
T&G Installation – When fitted correctly, tongue and groove flooring creates a firm, stable surface.
-
High-Quality Click Systems – Not all click-lock flooring is the same. Higher-end options provide a tighter fit and better longevity.
Strong flooring comes down to the material and how well it’s installed.
Which One Should You Choose?
Both tongue and groove and click-lock flooring have their advantages. If you’re after a strong, seamless finish that feels like traditional hardwood, T&G is a solid choice. If you prefer something quicker to install with the flexibility to remove or replace it later, click-lock might be the better fit.
