Gas Safe 599015 · Verified“I've been in boiler rooms across Wokingham for 20 years. I've seen the bodge jobs. I don't do them.”
I set up Thermotec in 2015 because I was fed up with how this trade treats people — vague time slots, one price quoted and another billed, repairs that need redoing three months later. Every job I take on across Wokingham, Woodley, Earley and RG40 gets the same treatment: I find out what's actually wrong, tell you what it'll cost before I touch anything, and fix it so it stays fixed.
