Windows and doors in Hambledon
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Peter and St Paul, the joint between an old wall and a newer frame is usually the first place rain gets in. For site and facilities teams at buildings such as Hambledon Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Window mastic for homes and businesses in Hambledon
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. If you have hard, cracked sealant around windows and mastic that’s falling out in pieces, we can help.

How it works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a morning for a couple of windows and a door. Somewhere like Hambledon needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- Mention any tricky access

Advice
How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What affects the cost of window mastic
We quote each job individually. These are the things that affect it:
- The old material and how stubborn it is
- Which sealant suits the joint
- Any working-time requirements on site
- How many areas need sealing
Doing several joints on one visit is normally more efficient than separate visits. We’ll send you a clear quote for the lot.
What we need to know
When you call or email, it’s useful to know:
- Whether it’s a home or a business
- The address or postcode of the job
- How we’d reach the joints
- If someone has resealed it before
We quote each job on its own. Just ring 0345 464 0079 or send us an email with the details and send photos if you have them.
FAQs for Hambledon
Is Hambledon within the area you cover?
Yes. Hambledon is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What guarantee comes with window mastic in Hambledon?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Can resealing stop a draught around my window?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Can new window sealant be painted?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you’re decorating and we’ll choose accordingly.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Are you fully insured?
Yes. Full insurance covers our work.
Why act early in Hambledon
Resealing frames is a short job: the visit takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Older cottages and farmhouses around Hambledon 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 a rough estimate. That is why we ask a few questions first and agree the price before starting.
What you get with us
- Anti-fungal sanitary silicone in wet areas
- White, clear, grey or coloured to suit, where the product allows
- You choose the colour before work begins
- Neat joints and a tidy finish

- Faulty window hardware
- A frame that has rotted at the joint
- Draughts through the window seals rather than the frame
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

Work for landlords, hotels and businesses
If you manage several properties in or around Hambledon, jobs at different addresses can go on one quote. Send us the addresses and the work at each.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
