What Clients Say
“A pipe burst behind the boiler on a Saturday evening and water was flooding the kitchen. They arrived within the hour and fixed it. Would give five stars but expected a slightly longer warranty on the repair.”
“Heat pump installation. I was worried about the language barrier, but they speak Russian and Ukrainian - no stress at all. Work done cleanly, running without issues since the first winter.”
“Old gas boiler swapped for a condensing one. Arrived on time, cleaned up, explained the new controls. Fair price for the market, work done without complaints. Will call again.”
“New plumbing and drainage in a renovated flat. Four days of work, not a speck of dust left behind. They suggested where to save on materials without cutting corners on what matters.”
“Underfloor heating across the whole flat. Had to relocate one thermostat - the initial position wasn't ideal. Fixed it without any fuss or extra charge. Even heat throughout.”
“Full central heating on a turnkey basis for a renovated flat. Came with a clear proposal, explained each phase, kept to the schedule. No drips, no pipe knocking.”
“Called them to repair the office boiler. The repair itself was done well. However, they didn't show up on the agreed day and didn't call ahead - came only after rescheduling. Too big a slip for full marks.”
“Replaced four radiators - three in rooms, one in the bathroom. Bled the old circuit, swapped radiators and thermostatic valves. The whole flat heats evenly now. Neighbours asked who we used.”
“Stuck valve at 2 am, flat going cold. Technician arrived in 50 minutes and fixed it. Slightly scraped the plaster around the pipe but otherwise completely satisfied. Grateful for the night call.”
“Full bathroom from scratch - new waste pipe, new supply pipes, new mixer tap. Suggested a better layout, took care of everything. Did more than I originally planned and at a fair price.”
“Annual boiler service before winter. Everything checked and adjusted. Staff speak Czech and Russian, pleasant to deal with. One star off only because the service window was shorter than expected.”
“They installed our heat pump and we have used their annual service ever since. Every year on time, with a condition report and specific recommendations on what to address before it becomes a problem. That is how service should work.”
“Underfloor heating in the children's room and hallway. Schedule kept, cleaned up to the last speck. One star off - the explanation of the controls was too brief.”
