Window & door mastic in Warnford, Hampshire

How the job changes by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
Window mastic in Warnford
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Typical jobs include rushed sealant from a window installation and hard, cracked sealant around windows, on aluminium frames, uPVC windows and patio & French doors.
Mastic can only go onto a dry, clean joint, so window work in Warnford is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Every job is covered by a one-year guarantee.

When it isn’t the sealant
We will not take on work that will not last, so these are the limits:
- Condensation trapped between the panes
- Rotten timber, which needs a joiner first
- Penetrating damp from a failed cavity tray or render

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. In a small place like Warnford, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What window mastic looks like in Warnford
Historic houses like Hinton Ampner House (about 3.1 miles north-west) are a reminder that the area around Warnford 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Warnford, as everywhere, window mastic is only as good as the preparation behind it.

Your questions about window mastic in Warnford
Will you come out to Warnford?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What guarantee comes with window mastic in Warnford?
All our work, in Warnford and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access.
Can you do the inside joint as well?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.
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.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

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 peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Warnford can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, 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.
Why book with us
- White, clear, grey or coloured to suit, where the product allows
- A sealant colour to suit the surroundings
- Approved under the ARBOMaster scheme
- Neat joints and a tidy finish

Common problems we fix in Warnford
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
Look out for any of the following:
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
- Sealant in the wrong colour for the frame
- Untidy mastic left by window fitters
For an older house near a landmark such as Church of Our Lady, the joint between an old wall and a newer frame is usually the first place rain gets in.
