Q: Hi Dr Dulux, we're in the process of selling our home, but the outside of our property isn't looking its best. What can we do to make it look more appealing to buyers? Any tips on which colours we should go for? Harriet, Wembley

A: Harriet, I'm glad you asked – exteriors always get neglected, and yet a tidy façade is crucial if you want to make a good first impression.

It's even more important if you’re trying to sell your property, as a new study by Dulux Weathershield found that adding a lick of paint to your home’s exterior can help increase its perceived value by up to 25%.

A tired-looking façade is one of my personal bugbears, but I'm not the only one. Weathershield's study found that flaky front doors are Brits’ top pet hate when it comes to the outside of people’s homes (followed closely by crumbling masonry and cracked walls).

So if you only do one thing to smarten up your home’s exterior, I recommend you give your front door and windowsills a fresh coat of paint.

Dulux Weathershield Masonry paint is a good option, and will instantly improve your home’s appearance. It also comes with the new Weathershield Promise on qualifying products, so you can be confident that it will resist peeling, flaking and staining caused by mould.

In the unlikely event that you do suffer any of these issues while you’re still living in your home, we will return the value of a replacement product *. All you need to do is register your purchase with our easy-to-use portal.

As for the colour – normally, I'd say go wild and pick whatever shade takes your fancy, but if you're looking to sell, go for a crowd-pleaser (you don't want to scare off potential buyers, after all). Weathershield found that 46% of Brits prefer the exterior of properties when they’re painted classic white or cream, followed by pale blue (19% - see Frosted Lake), yellow, mint green, then lilac, red, navy blue and grey.

If you're keeping it neutral, check out Cream Tea, which is especially good for cottages or countryside homes. Alternatively, try on-trend Gallant Grey, my colour of choice for urban homes and Victorian terraces.

You'll be so pleased with the results you may reconsider moving home after all…
