Would recommendPosted on Google LailaTrustindex verifies that the original source of the review is Google. If you listen to one review let it be this one!!!! I cannot begin to articulate how fabulous Jase and his team were. Unfortunately in 2020 COVID time my mom was scammed out of £10,000s of pounds for a shoddy bathroom job by some cowboy contractors. It was completely unsafe and unsanitary for a house full of children. As you can see from the video, the bathroom was an absolute state. I am so grateful to Jase and his team for providing my mom with such a beautiful transformation!! Jase was so patient and professional with us and really ensured our hopes for the bathroom were listened to. He is attentive and only accepts high quality work from his colleagues. He provides clear and client-professional contract that protects you and his company which gives you so much reassurance in his work. I cannot thank Jase enough for everything he has done. Please please please take Jase on board your team if you know you want a good job done for your project!! I’m bringing him and his team back for more work in the house!😊Posted on Google Sarah KilpatrickTrustindex verifies that the original source of the review is Google.

I installed my new faucet and they also put a pipe in and charged me a total of 800 pounds, then I told them I can't afford it, they lowered it to 715 pounds and the job was poor, it's 45 minutes.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
