Different surfaces, different methods
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Don’t paint over the silicone
- Clean frames with a soft cloth and soapy water
- Ventilate rooms so frames don’t stay wet inside
- Keep timber frames painted
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just phone 0345 464 0079 or email us.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
Honest limits
Before you book, it’s worth knowing the limits:
- A door that needs adjusting, rehanging or new seals
- A frame that has rotted at the joint
- Penetrating damp from a failed cavity tray or render
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
How it works
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of frames, longer for a whole house for a typical job. For a village or hamlet like Young's End, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Preparing for the visit
- Mention any tricky access
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property

Advice
Questions from Young's End
Do you cover Young's End for window mastic?
Yes, Young's End is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Can you help a landlord with a rental near Cressing station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Does the work come with a guarantee?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is the new sealant paintable?
Silicone generally will not take paint. Let us know beforehand, and we will use a paintable product where it suits.

What we need to know
There’s no need for technical detail. Just tell us:
- What’s wrong with the joints now
- The address or postcode of the job
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or email us.
What we’re called out for in Young's End
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Look out for any of the following:
- Gaps left after new windows were fitted
- A bead that doesn’t match the frame
- Mastic that is falling out in pieces
- Cracked or shrunken mastic around the frame
If you look after a building such as White Court School, the mastic around its windows and doors needs looking after like any other building’s.
