Window mastic in Wash Water, done properly
A window frame and the wall around it expand and shrink at different rates. 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. Typical jobs include sealant in the wrong colour for the frame and cracked internal joints between frame and plaster, on uPVC windows, window sills and aluminium frames.
In a village or hamlet like Wash Water, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Different surfaces, different methods
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We will point out any rot we find, as a joiner will need to deal with it.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
How we quote for window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- Which sealant suits the joint
- The number of rooms or windows
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
Asking for a quote
You do not need to know the technical terms. Just tell us:
- Whether it has been sealed before
- A few pictures by email, if you can
- Any access issues, like height or stairs
- The address or postcode of the job
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or drop us an email.
Frames and glazing around Wash Water
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Highclere Castle (about 2.7 miles south) are a reminder that the area around Wash Water has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near St Luke Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Newbury station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Horris Hill School, larger buildings have plenty of frames, and the mastic around each one ages.

Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Wash Water, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Why us?
- We leave the area clean and tidy
- We agree the colour with you first
- Experience in homes, commercial sites and hotels
- We never seal over old sealant

The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Wash Water, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive

When something else is needed
In fairness, there are a few things sealant will not fix:
- Rotten timber, which needs a joiner first
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Penetrating damp from a failed cavity tray or render
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.

Your questions about window mastic in Wash Water
Is Wash Water within the area you cover?
Yes, Wash Water is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Newbury station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you when we finish.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

Can you get sealant to suit coloured frames?
