What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours, depending on how many joints need doing for a typical job. In a smaller place like Portsmouth Point, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.

- Mention if the joints have been sealed before
- Clear items away from the joints we are working on

Signs you need glazing silicone in Portsmouth Point
The wrong sealant is a common cause. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
Most people get in touch when they notice one of these:
- Glazing silicone that has cracked or come away
- Water running down inside the glass
- Water getting into a conservatory at the joints
- Leaking glazing joints on a rooflight
If you look after a building such as St Jude's CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before you book
- What preparation is included
- Are they insured?
- What happens if the job turns out different
- Who does the work, and how experienced they are
Why it’s worth doing now in Portsmouth Point
If the problem is a misted unit or a broken panel, sealant will not help. We will tell you that rather than seal it anyway and point you to a glazier or roofer. Around Portsmouth Point, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Doing several joints on one visit generally makes better use of the time than several visits. We’ll give you a clear quote for the lot.
Why book with us
- Neat joints and a tidy finish
- Trusted Arbo and Everbuild sealants
- An ARBOMaster approved applicator

Your questions about glazing silicone in Portsmouth Point
Can you help a landlord with a rental near Portsmouth Harbour station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Does living near the coast affect glazing silicone in Portsmouth Point?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Which silicone is used for glass joints?
A glazing-grade silicone is best. Ours is a neutral-cure glazing silicone and anti-fungal silicone in wet areas.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Windows and doors in Portsmouth Point
Portsmouth Point is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Portsmouth Garrison church, the joint between an old wall and a newer frame is normally the first place rain gets in. Letting a property close to Portsmouth Harbour station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
