Window mastic in Brockbridge: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Meonstoke Church of England Infant School? Then the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Mary and All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Window mastic in Brockbridge, done properly
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on uPVC windows, timber windows & doors and composite doors, and people most often call us about sealant in the wrong colour for the frame and mastic that’s falling out in pieces.
Around Brockbridge, 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.

Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a small place like Brockbridge, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

FAQs for Brockbridge
Is window mastic in Brockbridge guaranteed?
All our work, in Brockbridge and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Brockbridge?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or drop us an email.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Can you match the sealant to my frames?
Yes, in most cases. Tell us the frame colour when you get in touch and we will use the nearest match.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Repaint timber before it’s bare
- Do not use solvent cleaners on the joint
- Look round the frames every year or so
- Wipe condensation off the frames
Most silicone sealants won’t take paint, so mention any painting plans before we start. There are paintable sealants for joints that need it.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
How we quote for window mastic
The quote reflects the job in front of us. We take into account:
- Any working-time requirements on site
- Any mould that needs treating
- The number and length of the joints
- Whether old sealant or filler has to be cut out
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear quote for the lot.
Asking for a quote
To help us quote quickly, please include:
- Where the job is, and your postcode
- How we’d reach the joints
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or email us with the details, and photos are welcome.
Surface by surface
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. In a small place like Brockbridge, access is normally 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.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any tricky access
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
