Different surfaces, different methods
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.

Landlords, agents and businesses in North Mundham
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Questions from North Mundham
Is North Mundham within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is glazing silicone in a coastal place like North Mundham any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Can tenants book the work?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you offer different sealant colours?
In most cases you can choose. We’ll explain which colours are available.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
What happens if it’s left?
A quick bead over the old sealant might stop a drip for a while, but silicone does not stick to silicone and water soon finds its way back. A proper reseal is the lasting answer. Older cottages and farmhouses around North Mundham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

The process
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to most of a day, depending on the size of the job. In a small place like North Mundham, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.

Windows and doors in North Mundham
North Mundham is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on glazing joints and frame seals, especially on the side facing the sea. With historic houses such as Goodwood House (about 4 miles north) nearby, there’s older building stock in the area around North Mundham as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Chichester station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Homes close to The Parish Church of St Stephen include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as North Mundham Primary School, the mastic around its windows and doors needs looking after like any other building’s.
North Mundham is about 2 miles south-east of Chichester, in West Sussex. Jobs in North Mundham get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee.

What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Condensation trapped between two panes
- A sagging or failing conservatory roof
- Cracked or broken glass
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Conservatory frames
- Rooflights
- Glass-to-frame joints
- Glass-to-glass joints
- Shower screens
- Glass balustrade bases
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Open vents or windows to let moisture out
- Act on drips or damp patches early
- Check the silicone on glass every year or so
- Avoid scraping close to the bead
Check the joints once a year. Catching a split early keeps the repair small, before water gets in.
Conservatory leaks rarely stay small. Water runs along frames and down walls, so get it looked at when you first see it.
