When you look at a beautiful new hardwood installation, you are only seeing half the story. The secret to a floor that doesn't squeak, doesn't gap, and feels solid underfoot lies beneath the surface. Subfloor preparation is arguably the most critical phase of any flooring project, yet it is often the most overlooked by budget contractors. At Tri Point Flooring Inc, we’ve been the Cary area’s hardwood experts since 2006 because we understand that what you don’t see is just as important as what you do see.
Why the Subfloor Matters
A hardwood floor is only as good as the foundation it sits on. If the subfloor is uneven, damp, or structurally weak, your new hardwood will eventually reflect those issues.
Common problems caused by poor subfloor prep include:
Squeaks and Creaks: Often caused by the wood rubbing against a loose subfloor or nails that haven't properly gripped.
Cupping: If there is excess moisture in the crawlspace or subfloor, the hardwood will absorb that moisture from the bottom up, causing the edges to rise.
Bouncing: An uneven subfloor creates "voids" under the wood, leading to a hollow sound and a "spongy" feel when walking.
When our professional crews arrive at 8:30 am, the first thing they do is assess the condition of your existing subfloor. We believe in highest quality service, which means we never install over a compromised foundation.
Leveling and Sanding the Subfloor
In many Cary homes, particularly older ones, the plywood or OSB subfloor may have high spots or low spots. We use specialized levels to check the entire surface. High spots are sanded down, and low spots are filled with self-leveling compounds or shimmed to ensure a perfectly flat plane. This ensures that when we install brands like Bruce, Hartco, or Somerset, every plank sits flush and secure.
We also check for "subfloor noise." Before a single plank of hardwood is laid, we re-fasten the subfloor to the joists using screws if necessary. This extra step is what eliminates those annoying midnight squeaks and ensures your floor feels like a "warm hug" rather than a creaky obstacle course.
The Role of Moisture Barriers
In the humid climate of North Carolina, managing moisture is a non-negotiable part of the process. We use moisture meters to test the subfloor's moisture content before installation. If the readings are too high, we investigate the cause—often a damp crawlspace—and wait for the environment to stabilize.
We always use high-quality underlayments or moisture barriers between the subfloor and your hardwood. This acts as a shield, preventing seasonal humidity changes from affecting your floors. As we highlight in our About Us section, maintaining proper moisture conditions (between 30% and 50% humidity) is a shared responsibility, but we ensure you start with the best possible protection.
Meticulous Quoting and Transparency
Because subfloor issues can sometimes be hidden under old carpet, our quotes are designed to be as clear and meticulous as possible. We don't like surprises any more than you do. If we discover that your subfloor needs significant repair, we communicate that immediately. Our online platform allows you to review and accept updated project details 24/7, keeping the project moving forward without stress.
Our team of mature, hard-working installers and finishers is trained to treat your home like their own. This culture of excellence is embedded in everything we do, from the first measurement to the final coat of finish.
