Lee from The Mastic Guys came out to see me yesterday as we had a really bad leak from poor sealing around our bathtub. It’s been happening for a while and was dripping into the room below. I called Lee after reading several reviews and he gave me a quote based on some pictures I sent to him. Once he got here, the very next day as it was an emergency, he said the issue was way more serious. Normally at this point you expect the worst, and the price to start rising and all the old tricks of the trade to start, but nothing of the sort happened. Lee explained the problem and said to leave it to him and he would sort it for me. He was here for about 2 hours and when my Mrs and I went to look at the work he’d done we were over the moon. He advised us on what we needed to do moving forward and he left the.bath and sink looking amazing. He was also the cleanest builder I’ve EVER dealt with. I told Lee that as I thought he’d gone above and beyond what he thought he was coming to do for us, he should charge more, but he wouldn’t let me and he stuck to the original quoted price. I will definitely be using The Mastic Guys again and I’d recommend this company to anyone looking for this service. Thanks for everything Lee.

I had a leaking shower tray where the mastic had failed due to poor installation. Phoned Lee and he answered the phone right away (on a Sunday). Came in a few days and fixed the problem and explained why it had happened. Very professional and very knowledgeable about all things to do with sealant for baths and showers. Lee made a first class job of it and he was a pleasure to do business with him. I have no hesitation in recommending him.

We have now used Lee twice to have bathrooms, showers and other areas in our properties sealed. The jobs have always been done to a very high standard not just aesthetically but also in terms of endurance. Lee is reliable, professional, very clean and a true perfectionist. We cannot recommend enough the service that the Mastic guys provide. The results are fantastic!
Neil Stone
Great service and finish on the re-mastiking of the bath. Would recommend
Patricia Clampett
This is the third time we’ve used the services of The Mastic Guys (3 bathrooms, different properties). They always do a professional job and leave the area clean and tidy. This time Lee had a difficult challenge but did a brilliant job of removing the old sealant, cleaning and prepping the area before resealing. I highly recommend The Mastic Guys
Helen Poulain
Lee of The Mastc Guys replaced the mastic in both our bathrooms. He did a tremendous job taking off the shower doors and doing a really thorough job. Our bathrooms look like they have been totally renovated. I wish Lee had fitted them in the first place. Lee works to a very high standard, I would definitely recommend him.
Taylor Cassidy
The Mastic Guys were fantastic! I couldn't be happier with the service I have received from them and would 100% recommend them to friends and family in the future. You won't be disappointed when choosing these guys for all your mastic work.

Very pleased with the work carried out. Lee booked us in quickly and stuck to the arranged date and time. All the old mastic was removed and nice, clean fresh beads re-applied. We had problems with our shower tray and screen prior to Lee’s visit, but now we are leak free and it looks great. Thoroughly recommended. Thanks again Lee!
