When to call us in Chilton
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Keep an eye out for any of the following:
- Cracked sealant at the sill ends
- Cracked or shrunken mastic around the frame
- Mastic that’s falling out in pieces
- Draughty joints inside around the window
Rented homes near Didcot Parkway station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Window mastic in Chilton: 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 usually the first place rain gets in. Schools such as Chilton County Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What affects the quote in Chilton
The quote reflects the job in front of us. We take into account:
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and give you a clear price before work begins.
Asking for a quote
To make quoting easier, please include:
- Roughly how big the job is
- Whether it has been sealed before
- Pictures of the joints, sent by email
- The address or postcode of the job
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Look round the frames every year or so
- Keep drainage slots and sill grooves clear
- Do not paint over the silicone
- Keep jet washers away from the mastic
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Chilton: your questions answered
Is Chilton within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Chilton in your area for window mastic?
Yes. Our work covers London and the South East, and Chilton is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
How long should I leave it?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
Why deal with it now?
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Where a wall is exposed, as many are in small places like Chilton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How it works
Once we’re on site, we check the joints match what you told us. 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. In a small place like Chilton, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- 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.
How to prepare
- Clear the area around the work
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
