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, with every joint prepared, sized and tooled by hand — designed for a clean, watertight and professional finish.

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 close attention to detail, with 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 finish on our new bathroom. GE Sealant Solutions did all the silicone work and the attention to detail was spot on, especially around the shower and window. The black silicone finishes everything off perfectly. Would definitely recommend!

Really pleased with the work from GE Sealant Solutions. Had the old silicone cut out and the shower enclosure completely resealed, the finish looks spot on and has made a huge difference to the bathroom. Would definitely recommend.

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.

Asked Giles to seal in the kitchen and shower as previous efforts ruined the look of a newly fitted kitchen and bathroom, now, at long last both areas look pristine. very quick work from Giles, but excellent finish and worth calling him in.

The magic mastic man. What can I say. Spot on job from Giles. Sealed all of our downstairs to give a clean finish between the skirtings and LVT flooring. Sealed all around the kitchen. Also resealed our bathroom. Everything looks clean, sleek and fresh and gives the our home a nice finish👌🏽
