Glazing silicone in Wellhouse
Glass and frames expand and contract differently, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. If you have leaking glazing joints on a rooflight and mouldy sealant around glass panels, we can put it right.
In a village or hamlet like Wellhouse, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job, large or small.

Why act early in Wellhouse
You don’t need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes. In a small place like Wellhouse, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

How it works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours, depending on how many joints need doing. In a small place like Wellhouse, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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, then guaranteed for a year.
What else we do in Wellhouse
How to look after the new joints
A little care helps the new joints last. Our advice:
- Inspect the sealant on glazing annually
- Wipe the screen down after showering
- Keep harsh solvents off the silicone
- Check the gutters above the glazing for debris
Don’t use blades or scrapers near the bead when cleaning the glass. Stick to a soft cloth.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.
What glazing silicone looks like in Wellhouse
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Shaw House (about 3.7 miles south-west) are a reminder that the area around Wellhouse has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Homes close to Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Hermitage Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Quotes for glazing silicone in Wellhouse
We do not publish a price list, because jobs vary so much. What we look at:
- How many areas need sealing
- Access and height
- Any mould that needs treating
- The number and length of the joints
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- If it’s domestic, commercial or a hotel
- Where the property is
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved.
What the job involves on each surface
Rooflights
A rooflight faces rain and sun from above. The sealant around the glass and frame wears faster than most.
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.

How long does the job take?
It depends on the size of the job, but as a guide it takes a few hours, depending on how many joints need doing. We will give you a better idea when we quote.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Why not top up the existing silicone?
New silicone won’t bond to old silicone and water gets between the layers. The old bead always comes out first.

Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
When to call us in Wellhouse
Using a sealant not made for glass causes many failures. Some products do not bond well to glass, and acetoxy types can attack some frame materials.
Any of these means the joints need attention:
- Leaks where conservatory glass meets the frame
- Glazing silicone that has cracked or come away
- Black or yellowed silicone on glass joints
- Water escaping where a screen meets the wall
Letting a property close to Thatcham station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.
