Mastic Man Grays

The Professional Bathroom Siliconing Experts

Have you had enough of looking at dirty mastic in the corner of your bath, shower or window frame? Dirty mastic is caused by bacteria getting into the silicone, which can build up over time due to poor ventilation, inadequate prep work or low quality sealant.

Absolutely amazing job - even better than the original! I was recommended this Company by a friend who had heard of them but not used them. I was blown away by the high standard/finish. Definitely recommend 😃

Lee was amazing - we had a new en-suite refurb in August ‘23 and had nothing but problems with the shower enclosure, as it wasn’t sealed properly. Having fallen victim to a couple of very good scammers recently who claimed they could mastic, we then needed yet another repair & found The Mastic Guys via a web search. The tray, mastic and gaps were such a mess that simple mastic was not going to work, but Lee was expert at suggesting alternatives and he fitted a sealant trim which actually looks better than the original fitting! Professional, polite, and faultless attention to detail - if you need anything sealed, Lee is an expert and you can’t go wrong (just check the before any after pics in my review!). Thank you Lee for finally giving us a shower enclosure we can use without leaks! :-)

Lee worked on several areas of my bathroom and kitchen including around my bath, kitchen sink and worktop. He made a very neat and precise job with the mastic. He also repaired parts of the tiling in my shower which had come loose and resealed the base for me. I am very pleased with the work he did and he was extremely helpful. I felt Lee went above and beyond when he was working on these jobs. I would definitely recommend him to anyone.
Hassle free quote given, booked in with ease and was on time. Very professional and kept me informed and showed me the reason why to fix the leak it would be a little bit more and require additional materials. There was no pressure to carry out the additional work only an honest opinion. Was more than happy with the end result (no leaking shower) and very happy there was zero mess left and provided me with all the photos and invoice to allow me to lodge a complaint with the original installer (different company entirely). The end result of the work is better than I was expecting and would highly recommend this company.
