About our glazing silicone in Houghton
A frameless shower screen depends on its silicone. Leaks normally come from the wall joint or the tray joint, and we reseal both. If you are dealing with glazing silicone that has cracked or come away and a quick top-up bead that didn’t last, we can put it right, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Houghton is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee, whatever its size.

How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether there’s mould to deal with
- The number and length of the joints
- Whether the work is at height
- The old material and how stubborn it is
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and send you a clear quote before any work starts.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- If someone has resealed it before
- A few photos by email, if you can
- The address or postcode of the job
Every job is quoted individually. Just phone 0345 464 0079 or email us with the details, and photos are welcome.
What happens if it’s left?
If the problem is a misted unit or a broken panel, sealant won’t help. We say so plainly and point you to a glazier or roofer. In a small place like Houghton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Honest limits
New sealant cannot fix everything, and we’ll tell you before we start. Sealant won’t put right:
- Glass that needs replacing
- A roof that has moved or dropped
- A sealed unit that has misted inside
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

Questions from Houghton
Is Houghton within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Amberley station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
How long will you be here?
A typical job takes a few hours, depending on how many joints need doing, including preparation and clearing up. We’ll confirm how long when we quote.
Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Can you reseal the base of a glass balustrade?
Yes. The sealant joint at the base can be renewed. Fitting glass is a separate trade.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
How much does glazing silicone cost in Houghton?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
The process
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours, depending on how many joints need doing. In a small place like Houghton, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

Houghton homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Bignor Roman Villa (about 2.8 miles north-west) nearby, there’s older building stock in the area around Houghton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Amberley station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Managing a site like Dorset House School? Then larger buildings have plenty of frames, and the mastic around each one ages.
Houghton is about 6 miles north of Littlehampton, in West Sussex. Houghton gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Across West Sussex, we cover 371 places, Houghton among them. We also work in Brighton, about 19 miles from Houghton.

Typical jobs here are in homes near Arundel Park and the streets around them. Houghton’s nearest station is Amberley station, about 0.5 miles north-east of the centre.

When to call us in Houghton
Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
These are the problems we’re asked about most:
- Water getting into a conservatory at the joints
- Split or lifting silicone on glass
- Black or yellowed silicone on glass joints
- Failed sealant around rooflight glass
For an older house near a landmark such as The Parish Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Glass-to-frame joints
Silicone at the glass edge seals it into the frame. When it splits, water can get into the frame.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.
