Where to use the caulking gun

Firstly, the very best sealant is Ultraclear - click here to see why Ultraclear is the best sealant for gaps and cracks and click here to see why using silicone is a draught stopping mistake.

Highly recommended to try!

We already have 2 caulking guns of our own. I'd been using the better of the two however it was very slow progress to fill the gaps around our home.

When I saw EcoMaster was hiring out caulking guns, I thought it worth trying theirs and am so glad I did. The handle is far more comfortable and the anti-drip feature means I don't waste Fillers Ultra Clear each time I pause during my work.

I've since bought the same type of caulking gun and will continue sealing the many gaps and cracks around our home.

Thank you for your wonderful review Elise. We are very pleased to hear that our products and services have been able to improve your homes comfort. We look forward to seeing you again.
