Why GE Sealant Solutions

Specialist sealant application. Done properly.

Sealant is usually the last thing done and the first thing noticed. We work on silicone and mastic every day, so the joints we leave behind stay clean, stay watertight and look like they were always meant to be there.

01

Specialist application

Silicone and mastic is not a sideline for us — it is the whole trade. Correct preparation, the right product for the joint, and a bead that is tooled properly.
02

Clean, precise finishes

Straight lines, consistent widths, careful colour matching, and the surrounding area left as we found it.
03

Domestic & commercial

From replacing failed bathroom silicone in a single home through to kitchens, flooring, windows, external joints and larger site packages.
04

Fully insured

Clear quotations, confirmed arrival times and straightforward communication from first message to finished work.

Really pleased with the work. Giles came round and re-sealed all of my external doors and windows and did a brilliant job. Really tidy finish, professional throughout and left everything clean afterwards. Would definitely recommend and will be using him again for any future mastic work. Cheers mate 👍

Really happy with the silicone work done for me. It was neat, clean and professionally finished, and everything was left tidy. Great job and I'd definitely recommend them.

Couldn’t be happier with the finished result! Really easy to deal with from start to finish, turned up when expected and took real care with the work. The sealant looks very neat. Would 100% use GE Sealant Solutions again.
