  When I asked if their follow up inspection would help us recoup the money spent having the insulation taken out, they hung up in me!!!! Do not trade with these guys!!

  Update: The company did contact me after this review and they were very nice, advising that the individuals we had doing the work have since left them. Our faith had already been knocked so we had already got another company to fix it who did a great job. I have improved my score to two stars following the good interaction, but I cannot remove it or improve higher since Thermal Guardian should have checked up on the work if they had concerns about their employees. If you do use them, make sure they give you documentation and check the work that's been done. Original review: We were pleased with the work, but we have just had an independent review and discovered that they were cowboys. I don't know if the company is genuine and they just sent us naff workers, but it's essentially just bubble wrap and there's still foam left. They didn't provide any guarantee or certification. Now we have to get another company in to redo it, paying all over again. So disheartened. It's impossible to know who to trust! Sharing this experience to hopefully save someone else.

  Tried calling on separate occasions to enquire about different insulation products for a quote. I was told “we are not interested”. Rude, uncooperative service. Avoid.

  Owner's reply

  Hi Karen, we did not tell you we are not interested. We have simply told you we cannot provide you with the service as what you need us to do is something we cannot facilitate. I really do hope you can find another company that can assist you. Thanks for contacting our services!

  Recently had foil insulation installed in my loft space. Very efficient team, polite and very clean and tidy. Too soon to comment on energy savings yet. I would certainly recommend this company

  The whole experience was fantastic. The salesman Phil, explained the installation process and I was able to get answers to my concerns before I had signed up. Very reassuring. The fitters turned up on time and again explained what they were going to do, They laid carpet protection from top to bottom of my house, all 4 floors were covered. When they had finished there was absolutely no mess left. I am looking forward to receiving the photos they took and showed me so I can show my family. A job well done.

  Very pleased with the service and work Thermal Guardian has recently done for us. Fitted new insulation in our loft and removed the foam . Friendly efficient workers. Took all the rubbish away and left my loft clean and tidy. I would recommend Thermal Guardian to anyone. Thank you

  Great company person who came out to me was very polite and helpful, walked me through the whole process of fixing my insulation and making my roof look a thousand times nicer, my roof now looks brand new and my insulation is no longer causing mold to my property. I could not recommend them enough.
