About our glazing silicone in Bullsmoor
We renew glazing silicone on conservatories, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. If you have water escaping where a screen meets the wall and split or lifting silicone on glass, we can help, on rooflights, glass balustrade bases and glass-to-frame joints alike. Some people call us the mastic man, others the silicone man or the sealant specialist, but the work in Bullsmoor is the same: proper preparation and the right sealant for every joint.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 07833 053749 or email us.

Leave it or put it right?
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before it shows. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Bullsmoor questions
Do you cover Bullsmoor for glazing silicone?
Yes, Bullsmoor is within the area we cover. We work across London and the South East. You can call 07833 053749 or email us and tell us what needs doing.
Can parking be tricky for a visit in Bullsmoor?
Parking in Bullsmoor, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Where do you work from?
We work from Crawley. Our applicators cover Bullsmoor.
Can you reseal the base of a glass balustrade?
We can, if the base joint is sealed. Photos help us see what’s there when you phone 07833 053749 or email us.
Is it enough to run a bead over the old sealant?
New silicone won’t bond to old silicone, so a top-up soon lets water through. We cut out the old sealant first.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Common problems we fix in Bullsmoor
UV light ages silicone and roof joints get the most sun. It goes brittle, cracks and stops sticking to the glass and frame.
It’s worth asking for a quote if you see:
- Leaks where conservatory glass meets the frame
- Mouldy sealant around glass panels
- Water escaping where a screen meets the wall
- Silicone pulling away from the glass
For site and facilities teams at buildings such as Honilands Primary School, its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- Whether the sealant suits the joint
- When the joint can take water or movement
- What happens if the job turns out different
- Whether they seal over old material or remove it
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Bullsmoor and across Greater London. We can quote a run of properties together, and we are fully insured.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
What glazing silicone looks like in Bullsmoor
With historic houses such as Forty Hall (about 1 mile south-west) nearby, there’s older building stock in the area around Bullsmoor as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St George's Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. Letting a property close to Turkey Street station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Aftercare tips
A little care helps the new joints last. We recommend:
- Do not leave a drip for the next storm
- Inspect the sealant on glazing annually
- Avoid strong solvents on or near the sealant
- Keep air moving in the conservatory
Squeegee a shower screen after each shower and let the room air. It helps stop mould getting into the silicone.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we will tell you which.

The process
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes a few hours for most jobs. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- 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.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Tell us about any water getting in
- Move anything stored near the joints
- Mention any tricky access

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we cannot put right
We will not take on work that will not last, so here’s what sealant cannot put right:
- Frames that have decayed or split
- Water coming through the roof rather than a sealant joint
- Cracked or broken glass
If in doubt, ring 07833 053749 or email us and we will say what we think.
