Window mastic for homes and businesses in Chineham
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you have draughty joints inside around the window and damp patches on the reveal after heavy rain, we can put it right, on timber windows & doors, aluminium frames and window sills alike.
Homes around Chineham range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Window mastic in Chineham: local notes
Historic houses like The Vyne (about 2 miles north-west) are a reminder that the area around Chineham has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Homes close to Christ Church Chineham include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Four Lanes Community Junior School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Basingstoke station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How to look after the new joints
Looking after new joints is easy:
- Use gentle cleaners on frames and sealant
- Keep solvents and bleach off the sealant
- Air rooms to keep condensation down around windows
- Make sure the drainage slots aren’t blocked
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

Leave it or put it right?
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. In an older home around Chineham, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What affects the quote in Chineham
Every job gets its own quote. This is what makes a difference:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- The number and length of the joints
What you pay reflects the work, not guesswork. That’s why we ask about the job first.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- The problem you’ve noticed
- The type of property
- A few photos by email, if you can
- Roughly how big the job is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Should I try DIY first?
Some simple jobs can be done by a careful DIYer. 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. Let us know about access when you ask for a quote so we can plan the job.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Can I paint over the new sealant?
Most silicone cannot be painted. Let us know beforehand, and we will use a paintable product where it suits.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take most of a day for a typical house, less for a few frames. Parking around Chineham is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Getting ready for the visit
- Mention any tricky access
- Move anything stored near the joints
- Tell us about any water getting in
