Window mastic in Winterbrook, done properly
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you have water coming in at the bottom corners of a door and leaking joints at the ends of sills, we can help, whatever the surface.
In a village or hamlet like Winterbrook, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All our work is covered by a one-year guarantee.

What we cannot put right
Sealant is not the answer to every problem, and we will tell you before any work starts. Sealant will not put right:
- A failed sealed unit that has misted up
- A door that needs adjusting, rehanging or new seals
- Broken hinges, locks or handles
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.

How the visit works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Winterbrook, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Keep children and pets away from the work area
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

Advice
Questions from Winterbrook
Is Winterbrook 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.
I let a flat near Cholsey station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. You’ll know the timing when we quote.
How the job changes by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
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.
Why it’s worth doing now in Winterbrook
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. In a small place like Winterbrook, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

How we quote for window mastic
Jobs vary more than people expect. What affects the quote:
- The size of the job
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
What to tell us for a quote
When you contact us, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- Where the job is, and your postcode
- Roughly how big the job is
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, call 0345 464 0079 or email us.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Frames and glazing around Winterbrook
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Brightwell Manor (about 2.7 miles north-west) nearby, there’s older building stock in the area around Winterbrook 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 is traditional sand mastic.
Homes close to St John the Baptist's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Cholsey station? Then renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Cholsey Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
