Hello, We need smoke alarm to be fixed or potentially to be replaced as it is constantly beeping at the moment, and even change of the batteries did not help. Additionally, we need to tighten the sink pipe as the connection drips water. Should be pretty straightforward. Let me know if you can visit tomorrow please, and what is your offer. Thanks Dominik


The professional service was fantastic and on time. I am really happy with Mohammed's service. I will be more than happy to hire him again in the future. Thanks a lot.
