Quotes for window mastic in Hightown
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- Whether the work is at height
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How many joints, rooms or windows are involved
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or send us an email.
Window mastic for homes and businesses in Hightown
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you’re dealing with cracked internal joints between frame and plaster and damp patches on the reveal after heavy rain, we can put it right, on timber windows & doors, window sills and composite doors alike.
Homes in small places like Hightown often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

What we are called out for in Hightown
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
The problems people generally mention when they call include:
- Old mastic that has gone black or come away
- Draughty joints inside around the window
- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
For an older house near a landmark such as St John the Baptist, the joint between an old wall and a newer frame is generally the first place rain gets in.

Should I try it myself first?
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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- Worn gaskets, brush seals or a door that has dropped
- Faulty window hardware
- Damp problems in the wall away from the window
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before booking.

Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Will new mastic stop draughts?
It will if the frame joint is the problem. We check where the draught is before any work starts.
Hightown homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Avon Tyrrell House (about 3 miles south) are a reminder that the area around Hightown 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.
For site and facilities teams at buildings such as Ringwood Junior School, the mastic around its windows and doors needs looking after like any other building’s.

What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a morning for a couple of windows and a door. In a small place like Hightown, access is usually 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.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- Mention any tricky access

Leave it or put it right?
Resealing frames is a short job: it takes a morning for a couple of windows and a door. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Hightown can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first.
