Thank you very much
Bathroom Resealed
I called upon G1 Sealant to reseal my bathroom due to a very bad experience I had with a previous sealant company who not only did a poor job but had also damaged my shower tray too. John came out & done a fantastic job. I was delighted with the result’s. He is very meticulous on what he does. I would 100% recommend G1 Sealant to friends & family & I’ll be getting John back again soon to do my kitchen too.

John at G1 Sealant is a true gem of a tradesman. Communication was top notch from beginning to end. He showed up when he said, had all of the tools of the trade with him. He completed the indoor work to a high standard and even had time for an additional outdoor job. I am really pleased with his work.
