External wall insulation – the house facelift that also makes your home warmer

If your house was built before 1919, it’s likely that it was built with solid walls. Twice as much heat escapes from solid walls than cavity walls, so insulating solid walls can considerably cut your heating bills – you could have an additional £255 per year in your pocket. 

This type of insulation also reduces damp and improves your house’s curb appeal, often making it look brand new.

  • How much money will I save?

    With up to 50% of heat escaping through your solid walls, a significant amount of your money is being thrown away. External wall insulation will make your home more energy efficient, potentially saving you hundreds of pounds each year.

    An average property would save up to £255 each year from external wall insulation.

  • What is external wall insulation?

    External wall insulation is a layer of insulation fixed to the outside walls of your home. It creates a blanket around your home, restricting heat escaping in the winter and keeping you home cooler in the summer. It does this by fixing a layer of insulation material to the exterior wall of your home.

  • How long does it last?

    External wall insulation installs come with a 25-year CIGA guarantee

  • What's the process?

    Our team will fit polystyrene insulation boards around the outside of your property, creating a blanket around your home. These boards are then rendered and then finished with a range of finishes making your property more draft proof, damp proof, comfortable, and looking brand new.

  • How long does it take?

    Every home is different which makes it difficult to give an accurate idea, but we generally have most properties insulated within 10 working days. We can give you a clearer idea of timeframes once your house has been inspected.

  • What expertise does Baxter Kelly have?

    All of our technicians are fully qualified and accredited. We’re available to answer any questions you may have.

How would my house look afterwards?

Take a look at a classic external wall insulation job.  The additional cladding leaves a smooth, modern finish (particularly when compared to the house next door) that adds a beautifully crisp finish to any house.

It doesn’t matter whether the property is made of brick, concrete or stone, has a cavity or no cavity, or has a rendered or uneven finish – these are all suitable candidates for adding insulation. 

We cover the insulation with a reinforcement and then a special type of render.  You can select from a range of finishes from a textured render to a brick effect.

100% of our customers shared that external wall insulation has improved the aesthetic quality of their homes, not to mention making them warmer!

And as a beautiful knock-on effect, it can help increase your house’s value.
