02: Straight lines, consistent widths, careful colour matching and close attention to detail, with the surrounding area left as we found it.
03: From replacing failed bathroom silicone in a single home through to kitchens, flooring, windows, external joints and larger site packages.

Had the external windows sealed by GE Sealant Solutions and really happy with the result. The new sealant has given everything a much sharper finish and the workmanship was excellent. Would happily use them again.

MartineGoogle review · in the last week

We had our bathroom sealed by GE Sealant Solutions and the difference it’s made is brilliant. Really crisp lines throughout and the colour match was perfect. Would definitely use again.

SamGoogle review · a week ago

I’ve used GE Sealant Solutions for quite a few projects now and the work is always spot on. Just had another bathroom sealed and really happy with how it’s turned out. Would definitely recommend.

JohnGoogle review · a week ago

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!

Had GE Sealant Solutions seal around our newly fitted flooring and couldn’t be happier with the result. The finish is really sharp and makes the whole floor look properly finished. Great attention to detail and would happily use them again.
