When the UK experiences a heatwave, it’s not just the temperature that rises. Your flooring can feel the effects too. Extreme heat, direct sunlight, and changing humidity levels can all impact the appearance and performance of different types of flooring. Whether you're a homeowner or a facilities manager, here’s how to keep your floors in good condition when the weather gets hot.

Protect Against Sunlight Damage

Sunlight can cause discolouration in many types of flooring, including luxury vinyl tiles (LVT), laminate, wood, and even some carpets. It can also lead to fading and warping.

• Use blinds or UV-filtering window film to block harsh rays.
• Rearranging rugs and furniture occasionally helps avoid uneven fading.
• For commercial spaces with large windows, consider solar shades or tinting.

Manage Heat Expansion (Especially with Vinyl and Laminate)

Many flooring types, particularly vinyl, laminate, and engineered wood, naturally expand in heat. Without enough room to move, this can lead to buckling or gaps.

• Floors should always be installed with expansion gaps around the edges.
• Avoid placing heavy items directly against walls that might trap the flooring.
• If you notice raised edges or movement, it’s best to get a professional to take a look before damage worsens.

Monitor Indoor Humidity

Hot weather can reduce indoor humidity, which may dry out timber flooring. Rapid changes in temperature can also cause condensation, which is harmful to most flooring types.

• Keep rooms well ventilated, and consider using a humidifier if the air becomes too dry.
• When cleaning, use a damp mop instead of a wet one to avoid water damage.

Keep Floors Clean (Dust and Heat Create Problems)

Dry weather brings dust indoors, and when combined with foot traffic, it can act like sandpaper on your floors. This is especially damaging for polished surfaces and LVT.

• Use mats at entrances to trap dust and grit.
• Vacuum regularly using a soft brush attachment.
• Avoid harsh cleaners, as some may react with floors that are already warm.

Carpet Care During Heatwaves

Heat can loosen the adhesive beneath carpet tiles and affect underlay performance, especially in busy areas.

• Avoid dragging furniture across the floor, as heat-softened adhesives are more prone to damage.
• Maintain good airflow to prevent hot spots forming underneath the flooring.
• Check for signs of rippling or loosening and address them early to prevent long-term issues.

Don’t Forget the Underlay

Underlay doesn’t just improve comfort underfoot. It can help regulate temperature and reduce the impact of heat on your flooring. If you’re refurbishing, choosing a quality underlay is a smart way to protect your investment.
