External Wall Insulation (EWI) is a system that wraps the outside of your home in a layer of insulation board, finished with a render or coating. It's one of the most effective ways to improve the thermal performance of a property — reducing heat loss, cutting energy bills, and making your home significantly more comfortable throughout the year.

As temperatures drop and rainfall increases across Kent and South East London, the condition of your home's external render becomes more critical than at any other time of year. Water is the enemy of failing render — once moisture gets behind a cracked or hollow section, the freeze-thaw cycle through winter will rapidly accelerate the damage.

Maidstone is a town with an incredibly varied housing mix — from Victorian terraces in town centre streets like Bower Mount Road, to postwar semis in Bearsted and Weavering, to modern estates on the outskirts. The type of property you own has a direct bearing on which rendering system will work best.

If you're considering having your home rendered, one of the first decisions you'll face is choosing the right system. Two of the most common options are silicone render and traditional sand & cement render — and while both can transform the look of a property, they work very differently and suit different homes and budgets.
