About our window mastic in Upper Chute
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you are dealing with mastic that’s falling out in pieces and draughts coming in around windows and doors, we can put it right, on patio & French doors, uPVC windows and timber windows & doors alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Upper Chute is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
You get a one-year guarantee, the same in Upper Chute as everywhere else we work.

Leave it or put it right?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Upper Chute can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Frames and glazing around Upper Chute
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.
In the older streets around Church of St Nicholas, the joint between an old wall and a newer frame is usually the first place rain gets in. Around Upper Chute, as everywhere, window mastic is only as good as the preparation behind it.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Use gentle cleaners on frames and sealant
- Repaint timber before it’s bare
- Clear any debris from frame drain holes
- Wipe condensation off the frames
Silicone can’t generally be painted, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Your questions about window mastic in Upper Chute
Is Upper Chute in your area for window mastic?
Yes. Our work covers London and the South East, and Upper Chute is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.
Is there a guarantee on window mastic in Upper Chute?
All our work, in Upper Chute and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
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.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Is it worth trying it myself?
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.
How do I get a quote for window mastic in Upper Chute?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Do you have sealant for grey or black windows?
Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll use the nearest match.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How we quote for window mastic
The price is agreed before any work begins. It’s based on:
- When we can work, for business premises
- Access and height
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.
Asking for a quote
To make quoting easier, let us know:
- Where the job is, and your postcode
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we will come back to you with a quote.
What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. In a small place like Upper Chute, access is normally 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.
- The old mastic is cut out and the surfaces cleaned back.
- 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Tell us about any water getting in
