Window Mastic in Ravenstone
Our applicators work in Ravenstone on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- White mastic on grey or black frames
- Untidy mastic left by window fitters
- Draughts coming in around windows and doors
What we’re called out for in Ravenstone
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Common reasons people contact us include:
- Gaps between the frame and the inside reveal
- Leaking joints at the ends of sills
- Sealant in the wrong colour for the frame
- Rain getting in at the frame or under the sill
Around Ravenstone, as everywhere, window mastic is only as good as the preparation behind it.

Window mastic in Ravenstone
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We’re often asked to deal with black, perished sealant on frames and rain getting in at the frame or under the sill, on timber windows & doors, composite doors and aluminium frames.
Around Ravenstone, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, in Ravenstone and everywhere else we cover.

Ravenstone: your questions answered
Is window mastic in Ravenstone guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Ravenstone?
Yes, Ravenstone is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you work on first-floor windows?
Yes, where they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Can new window sealant be painted?
Most silicone can’t be painted. Let us know beforehand, and we will use a paintable product where it suits.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
When it isn’t the sealant
It helps to know what we can’t do:
- Draughts through the window seals rather than the frame
- Broken hinges, locks or handles
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Window mastic in Ravenstone: local notes
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.
In the older streets around Church of All Saints, the joint between an old wall and a newer frame is normally the first place rain gets in.

Why act early in Ravenstone
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. Around Ravenstone, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What we do, step by step
Before we leave, we go over the finished joints with you. The work normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on how much there is to do. In a small place like Ravenstone, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Before we arrive
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area

What the job involves on each surface
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
