What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Headbourne Worthy needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- 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.
Preparing for the visit
- For business premises, tell us about site rules or sign-in

Why act early in Headbourne Worthy
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Older cottages and farmhouses around Headbourne Worthy can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- ARBOMaster approved applicator
- Trusted Arbo and Everbuild sealants
- White, clear, grey or coloured to suit, where the product allows

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
A careful DIYer can reseal a simple joint, 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.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
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.
What affects the quote in Headbourne Worthy
The quote reflects the job in front of us. We look at:
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- Which sealant suits the joint
- The number and length of the joints
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
What we need to know
When you contact us, it’s useful to know:
- Whether it’s a home or a business
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
There’s no standard price list. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or drop us an email.
What we are called out for in Headbourne Worthy
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
The most common problems we see are:
- Black, perished sealant on frames
- Gaps where the sill meets the wall
- White mastic on grey or black frames
- Rushed sealant from a window installation
If you look after a building such as Kings Worthy Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
- Who turns up on the day
- How long to leave it before use
Headbourne Worthy homes and the weather
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Winchester station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What should I tell you?

Do you guarantee window mastic?
Yes. Each job is covered for 12 months, inside or out.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that is a different fix, and we’ll say so.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
