Hi welcome to my profile. I have been a qualified plumbing and heating engineer since 2010. I also have drainage qualifications and equipment ie a high pressure jetting machine secured to my van. So a blocked drain is never a problem to clear. I have done all types on installation and maintenance work in this field. I strongly believe a good work ethic is: "what I do and how I do it counts." I have worked for a major player in the construction field on behalf of a local Authority. I have also worked for a very well known plumbing franchise company owned by a major energy supplier. I cover all areas from Cambridgeshire to south London. However, I am committed to the jobs I quote for and the needs of you the customer. Please view my reviews and see a selection of works I have undertaken. I will continue to upload pictures so you get a sense of what you can expect from my work. Thank you for reading my profile.

The previous review was done under duress with Billy standing over me. The truth is, he disappears for considerable lengths of time (days), leaves equipment behind so you can't hire anyone else, switches his phone off so you can't contact him during this time and has the attitude of a bully. He removed our toilet to fix a blocked pipe but then left it so it wasn't fixed back to the floor properly and moved around, when we were in the process of selling our flat, with surveyors coming round. Not recommended.

My names Tom, I have been in the real estate sector for over 10 years and have done everything from general property maintenance, new bathrooms, painting/decorating, demolition contracts and most recently constructed 9 ultra high spec homes. High quality and impeccable workmanship are key values to me and ensuring the client is satisfied and more, with the work they are receiving. I am very well connected with all trades and can provide a top tier service for all types of project management no matter how big or small the job may be. I am also extremely capable at doing many manual labour jobs, but often favour a shorter timeline for my clients project completion and therefore prefer to draft in experienced trades to get the job completed. Above all I am very friendly, well spoken and always keen to deliver what is asked of me.
