Inflation affects everything from the food we buy in the supermarket to public transport.

As well as increases in supermarkets, energy bills are putting financial strain on many UK households.

Heating and electricity costs are now one of the biggest concerns for many Britons, according to a recent survey, especially with the winter months ahead.

Thankfully, DIY experts from Construction Megastore have shared a genius hack to slash energy bills by up to a staggering 10 percent every year, and, even better, it only costs £1.

Robert Quinton, director of construction at Megastore has explained how the item caulk can help Britons save money.

Quinton said: "Caulk is a budget-friendly sealant that, if used correctly, can play a crucial role in making your home more energy efficient. Applied around windows, doors, baseboards and bathroom fixtures, caulk seals small gaps and cracks where air, moisture and even pests can enter.

“By stopping air leaks, caulk prevents cold drafts in winter and keeps cool air inside during summer, easing the workload on heating and cooling systems. This tiny fix can cut energy bills by between five to 10 percent, translating to annual savings of around £150-£250 in the UK.

“Beyond energy savings, caulk protects against potentially costly water damage. In kitchens and bathrooms, where moisture is a constant, caulk keeps water from seeping into walls and floors, preventing mould growth and structural damage.”

Applying caulk effectively is key to making sure it provides a long-lasting, airtight seal. Quinton has given his tips for applying caulk at home.

Choose the right caulk:

Quinton said: “If you’re applying caulk to indoor areas prone to moisture, opt for silicone or acrylic-latex caulk with mould resistance. If you’re using the caulk outside, go for a weather-resistant caulk, ideally with UV protection.”

Prepare the surface:

“Before using the caulk, clean and dry the surface to remove dirt, old caulk or paint," he added. "A utility knife can be used to scrape away any existing caulk. This makes sure that the surface is smooth," he added.

45-degree angle:

The pro explained: “Cut the tip of the caulk tube at a 45-degree angle for more precise control. Start with a small opening, you can always cut more if needed.

"Use a steady, even pressure when applying the caulk, keeping the bead consistent for a cleaner look and better seal.”

Allow enough time for the caulk to dry:

Quinton advised: “Let the caulk cure according to the manufacturer's instructions. Caulk usually takes around 24 hours to be properly cured. This makes sure that the seal is durable and airtight.”
