Troner SL

They only work in the Madrid area... I called to find out more, and the only thing is, the girl who answers the calls could be a little friendlier. Just a little... I'm giving them 4 stars because of the great work the guys do in the videos; you can tell they're true professionals. But bad phone service can ruin a good experience... that's my opinion.

We hired them to repair the roof of our premises. They were quick and very professional. From day one, despite heavy rains, there wasn't a single leak. Very friendly and professional workers. Highly recommended.

They've waterproofed the same terrace three times (because it's covered by the warranty), and the problem persists. It holds for a while, but then water starts seeping through the roof again. Furthermore, we've experienced delays of months for repairs on several occasions.

Excellent work, very professional and fast. Highly qualified and experienced staff, very friendly. They are very attentive to the client's needs. Hiring them was a great idea. We've uploaded before and after photos of the waterproofing work on our terrace.

I'm delighted with Troner. It's true I waited a while for the terrace waterproofing, but it was well worth the wait. They are true professionals: diligent, hardworking, quiet, and clean. I can't thank them enough, and above all, they were wonderful people. Thank you so much! 100% recommended.
