What we are called out for in Pottersheath
Sealant laid over old sealant doesn’t last. Plenty of leaks come from a quick top-up over the old bead leaving a path for water.
Common reasons people contact us include:
- Leaking glazing joints on a rooflight
- Water getting into a conservatory at the joints
- Water tracking down the inner face of the glass
- Split or lifting silicone on glass
For site and facilities teams at buildings such as Oaklands Primary School, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- How the surfaces are prepared before sealing
- What guarantee comes with the work
- How the colour is chosen
- What happens if the job turns out different
About our glazing silicone in Pottersheath
Not every silicone suits glass. We use a neutral-cure glazing silicone that’s suited to glass and the frame, and we tool it to a neat, even finish. If you have mouldy sealant around glass panels and water escaping where a screen meets the wall, we can help, whatever the surface.
Somewhere as small as Pottersheath, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

How we quote for glazing silicone
Your quote is based on your job. We look at:
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- Mould in or behind the old joints
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.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- The problem you’ve noticed
- Whether it’s a home or a business
- Photos by email, if that is easy
- The address or postcode of the job
To get a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. You will have a clear quote before any work starts.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Act on drips or damp patches early
- Run a squeegee over the glass when you are done
- Ventilate the conservatory to cut condensation
- Check the silicone on glass every year or so
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we’ll tell you which.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from an hour or two to most of a day, depending on the size of the job and we leave things clean and tidy. Somewhere as small as Pottersheath, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks

Which silicone is used for glass joints?
A glazing-grade silicone is best. Ours is a neutral-cure glazing silicone and anti-fungal silicone in wet areas.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

What glazing silicone looks like in Pottersheath
With historic houses such as Knebworth House (about 1.6 miles north) nearby, there’s older building stock in the area around Pottersheath 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Michael and All Angels, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Knebworth station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Why deal with it now?
Resealing cannot fix a failed unit or a cracked panel. We say so plainly and point you to a glazier or roofer. Where a wall is exposed, as many are in small places like Pottersheath, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we’ll talk you through it.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
