Glazing & conservatory sealant in Preston, Kent
Glazing silicone for conservatories, rooflights, glass panels and shower screens for homeowners, landlords and businesses in Preston. Fully insured, ARBOMaster approved and guaranteed for a year.

How we handle glazing silicone in Preston
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. Typical jobs include a quick top-up bead that didn’t last and water tracking down the inner face of the glass, on shower screens, glass-to-glass joints and glass-to-frame joints.
Mastic can only go onto a dry, clean joint, so window work in Preston is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a 12-month guarantee.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What the job involves on each surface
Rooflights
A rooflight faces rain and sun from above. Its sealant ages faster than vertical joints.
Shower screens
A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
Why deal with it now?
A new conservatory roof is a big job. Where the water is getting in through sealant, resealing is far simpler. If the roof is the problem, we’ll say so. Where a wall is exposed, as many are in small places like Preston, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Do you need glazing silicone in Preston?
On shower screens, constant water and cleaning products wear silicone. Mould gets into it and the edges begin to peel.
These are the problems we are asked about most:
- Stained, discoloured glazing silicone
- Sealant that was laid over old silicone and failed
- Glazing silicone that has cracked or come away
- Cracked silicone between glass panels
Managing a site like Preston Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Frames and glazing around Preston
Historic houses like Goodnestone Park (about 4 miles south) are a reminder that the area around Preston has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Rented homes near Adisham station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you live in an older home near Church of St Mildred, the joint between an old wall and a newer frame is generally the first place rain gets in.

Preston questions
Do you work for landlords with property near Adisham station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Is Preston within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Do you reseal glass shower screens?
Yes. The old bead comes off without marking the glass, and the joints are cleaned and resealed.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most jobs. In a small place like Preston, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
- Move anything stored near the joints
