Tiny gaps can cause big, expensive comfort problems. Those wall vents, skirting board gaps, floorboard gaps, architraves and trim may not look like much. But add them together and your home might feel like it has a very casual attitude to comfort - and can easily cost you up to 20% of your heating / cooling bill! 

So that's the problem - the solution is a sealant of some kind.  We tested all them - and I mean ALL of them - cheap, expensive, silicone, polyurethane and acrylics.  

UltraClear (also called Fulaseal 701) is our absolute favourite gap sealant. It applies white so you can see what you are doing, then dries clear for a neat finish. No need to worry about colour matching sealant to two different surfaces or getting your caulking lines super straight ('cos you can't see it!) 🤭 It is a flexible, low-odour, DIY-friendly solution that works hard around your home.  Cleans up in water, and if you make a mess, wipe it all off and start again. Too easy!!  Its great for beginners and professional alike.
