The climate of Houston is characterised by high humidity with temperatures ranging at 70-90 per cent all year long. This might only appear as an out-of-doors inconvenience, but has a first-hand and usually ruinous effect on hardwood flooring in your house.

Hardwood is natural, porous and hence, absorbs and releases moisture depending on the surrounding environment. This unremitting exchange of moisture in such a humid city as Houston may result in serious flooring problems unless it is properly handled.

The Importance of Humidity to Hardwood Floors

When moisture is absorbed, the wood expands and when it dries; the wood contracts. This behavior among animals is problematic in an environment where the humidity is always high or varies regularly.

Houston is known to experience long-time exposure to moisture-laden air thus the hardwood floors are almost always found in the expanded form straining the floors structure.

Typical Effects of Humidity on Hardwood Floors in Houston

Expansion and Swelling

Too much humidity leads to the absorption of moisture and expansion of wooden planks. This leads to:

•  Cramped floorboards.
•  The contact of the pressure with the walls and stationary objects.
•  Loss of uniform spacing

With time, the floor may be distorted under this pressure.

Cupping and Crowning

Humidity difference in the wood may lead to deformation:

•  Cupping: The planks have edges that are raised higher than the center.
•  Crowning: The highest point of the plank is at the middle as compared to the edges.

Such problems usually denote unequal exposure of moisture either beneath (subfloor) or overhead (air humidity).

Buckling (Severe Damage)

In severe instances, the hardwood floors may completely detach themselves by fully separating with the subfloor a phenomenon referred to as buckling. This usually happens when:

•  The humidity is high over prolonged duration.
•  Expansion is not possible.
•  There was no correct spacing or moisture protection during installation.

One of the gravest and the costliest flooring issues is buckling.

Mold and Mildew Growth

The climate in Houston is humid which forms the perfect environment of mold and mildew, more so under flooring. This can:

•  Damage the wood structure
•  Produce unpleasant odors
•  Improve human health and indoor air quality.

Finish Damage and Seasonal gaps

Also the humidity changes have a hand:

•  In the humid climate – wood swells.
•  In the condition of less humidity (because of air conditioning) – wood shrinks.

This cycle can cause:

•  Gaps between planks
•  Finishes being cracked or peeled.
•  Shorter service life of the flooring.

Best Indoor Humidity of Hardwood Flooring

To ensure the integrity of hardwood flooring, indoor humidity must be within:

30% to 50%

This is the range, which exceeding it predisposes the damage in the long run.

Flooring Protection in Houston

Use a Dehumidifier

The dehumidifier is used to restrict the amount of moisture that is manufactured, particularly in the summer and rainy seasons.

Maintain Your HVAC System

Air conditioning removes humidity as well as temperature. The regular use stabilizes the indoor conditions.

Install a Moisture Barrier

In the case of new installations, the installation of vapor barrier under the flooring prevents the seepage of moisture upwards through the subfloor.

Monitor Indoor Humidity

Measuring the humidity: a hygrometer should be used regularly to monitor the level of humidity and adjust it as necessary.

Clean Spills Immediately

Water that may be left on hardwood floors may easily penetrate and cause deterioration due to moisture.

Red Flags of Humidity Damage.

Watch for these indicators:

•  Warped or uneven flooring
•  Musty odors
•  Visible gaps or swelling
•  Painful squeaky steps.

Expensive repairs can be avoided by early detection.

When to Call a Professional

Considering that in case of severe problems such as buckling, continuous cupping or even mold, it is better to approach a flooring expert. Expert evaluation is required in a humid city such as Houston to be treated and guaranteed solutions in the long-term.
