Cross End Window Mastic

- A bead that doesn’t match the frame
- Whistling draughts around closed windows
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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. All the old material has to come out first.
Window mastic in Cross End, done properly
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have rain getting in at the frame or under the sill and a bead that doesn’t match the frame, we can put it right, whatever the surface.
Around Cross End, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months, in Cross End and everywhere else we cover.

Windows and doors in Cross End
Historic houses like Hedingham Castle (about 4.7 miles west) are a reminder that the area around Cross End has older buildings as well as new. In older buildings, 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Bures station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as Parish Church of St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Cross End questions
Do you cover Cross End for window mastic?
Yes, Cross End is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Can you help a landlord with a rental near Bures station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we will tell you.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Cross 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.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before

How we quote for window mastic
Every job gets its own quote. This is what makes a difference:
- The number and length of the joints
- Whether there’s mould to deal with
- How easy the joints are to reach
- The old material and how stubborn it is
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
When you call or email, these details help:
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- Any access issues, like height or stairs
To get a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before we start.
Leave it or put it right?
Resealing frames is a short job: the visit takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. Where a wall is exposed, as many are in small places like Cross End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us and we will talk you through it.

Aftercare tips
A little care helps the new joints last. We recommend:
- Don’t use solvent cleaners on the joint
- Keep paint off silicone joints
- Keep paint and stain on wooden frames in good order
- Keep jet washers away from the mastic
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
