Why should I rent these tools instead of buying them?

Let’s be real—these are amazing tools, but you probably won’t use them every day. Renting means you get top-quality, professional gear for a fraction of the cost—just when you need it most. No need to invest hundreds in something you'll use once or twice!

What kind of projects are these tools good for?

They’re perfect for DIY home energy upgrades! The Flir Camera helps you see where heat is leaking. The PowerMate shows how much power your appliances are using. The Caulking Gun makes sealing gaps easier and neater. And the Stapler Kit is a must-have for installing underfloor insulation fast and securely.

I’ve never used tools like this—will I know what to do?

Yes! These tools are user-friendly, and we provide simple instructions (and video guides where needed) so you can get great results—even if you’ve never done anything like this before. It’s all about giving you confidence to improve your home with ease.

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.
