John came out after I made a call to fix my leaky and wobbly toilet. He was able to quickly identify the problem. He sourced the part and fixed it and also secured the toilet basin to the floor. He was quick, professional and tidy! Very polite and willing to go the extra mile for customers. I'd recommend him for any plumbing jobs.

We recently used John for a leak investigation for one of our managed properties in London, and was really impressed with the service he provided. He was punctual, professional, and thorough in his approach. Provided us with a report, photos and videos of his findings and advised on next steps. As property’s managers we work with a lot of contractors, and it’s always a pleasure to build a professional relationship with someone so reliable and knowledgeable. We will definitely be using John across more of our London portfolio in the future and have no problem in recommending him to others!

my tub was clogged for weeks all the Drano and other products I tried wouldn’t work. I knew I had to call a plumber for an affordable price. He came at a time that suited me best and fixed a three week problem in a little under 10 minutes. It’s almost like the problem never existed so grateful Would definitely recommend him for all your plumbing needs and definitely using him again . He’s well skilled and professional.

I had concerns with ADJEPONG, John Kofi of PLUMBING IN AND OUT LTD.,78 Copeland House, Garratt Lane, London, England, SW17 0NG. This plumber is clearly dis-honest with his customers. He told me before the job that he would charge me £75. Then after the job, he turned around & demanded £88 from me. Therefore, he does not keep his word. He then refused to issue me with a receipt for the work. He also uses high pressure sales techniques and intimidating behaviour with his customers to get them to agree to do a job with him. Finally, he did a job which was poor & shoddy & third rate which left me feeling un-happy with his poor quality standard of work.

I've used In and Out plumbers on two occasions. Both times they have been professional, courteous and arrived on time. They take care of my home, cleaning up any and all mess the job requires. Best of all, the pricing is very reasonable. The plumber also took time to explain what was wrong and how it could be fixed, even explaining why the slightly better stop valve he had to replace would present better value in the longer run, even though it was only a few pounds difference. I would have no hesitation in recommended them to work on your property.
