Excellent service and quality work!

A technician came to install trickle vents on several windows and an air vent, along with adjusting the bottoms of a few doors for better clearance. He was friendly and efficient, clearly explaining his actions and addressing a problem that arose with one window closing after the vent installation. Overall, a fantastic job! Many thanks!

Improvements in Room Ventilation

A technician came to install trickle vents on several windows and an air vent, as well as adjusting the bottoms of a couple of doors for better ground clearance. He was very friendly and efficient, clearly explaining his work and addressing an issue with one window that became difficult to close after the vents were added. Overall, a great job! Thank you!

Exceptional Support

My main contact throughout various projects has been outstanding. If I could rate his professionalism higher, I would. Despite some scheduling issues and minor problems, he addressed everything promptly and professionally. I can't speak for others' experiences, but my interaction has been top-notch.

Unpleasant Customer Service

I had a very negative experience speaking with a representative. He was rude and spoke aggressively, ultimately hanging up on me. I’ve been without heating since yesterday, and they want to charge for a problem caused by their installation. I recommend avoiding their service as they seem unhelpful and unprofessional.

Top-Notch Installation

I had internal extractor fans, wall insulation, solar panels, and a heat pump installed under a government scheme. Four different teams worked on the installations, all of whom were professional and did a fantastic job without any issues. Highly recommended!

Disappointing Experience

This company is a disappointment. Once they leave your property, you won’t hear from them again. They do not return calls or emails, and the heating was improperly installed, leaving it unresolved for nearly a year. I strongly advise against using their services!
