Window mastic for homes and businesses in Horsebridge
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on uPVC windows, aluminium frames and timber windows & doors, and the jobs we see most are draughty joints inside around the window and sealant in the wrong colour for the frame.
In a village or hamlet like Horsebridge, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
We stand behind the work with a one-year guarantee.

What window mastic looks like in Horsebridge
Historic houses like Mottisfont Abbey (about 2.5 miles south-west) are a reminder that the area around Horsebridge 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St James, the joint between an old wall and a newer frame is usually the first place rain gets in. Schools such as King's Somborne Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Mottisfont & Dunbridge station, renewing tired window mastic between tenants heads off draught and damp complaints.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Avoid blasting the frames with a pressure washer
- Keep timber frames painted
- Keep solvents and bleach off the sealant
- Walk round the house once a year and look at the joints
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.

Landlord and commercial work in Horsebridge
Letting agents and landlords in Horsebridge can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What we do, step by step
The work is kept neat and contained to the joints we are treating. The job normally takes a morning for a couple of windows and a door, and we tell you how long to leave it before we go. In a small place like Horsebridge, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.

Advice
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Horsebridge questions
Can you help a landlord with a rental near Mottisfont & Dunbridge station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Is Horsebridge within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you do upstairs windows?
Yes, if safe access is possible. For high or awkward windows, we will tell you what access is needed.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Where do you work from?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
What affects the quote in Horsebridge
Every job gets its own quote. This is what makes a difference:
- Which sealant suits the joint
- Working hours on commercial sites
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before we start.
What to tell us for a quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
- Whether it has been sealed before
- Any access issues, like height or stairs
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or drop us an email.
What we can’t put right
It helps to know what we cannot do:
- Condensation trapped between the panes
- Penetrating damp from a failed cavity tray or render
- Worn gaskets, brush seals or a door that has dropped
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
Joints and surfaces we work on
- Window sills
- Composite doors
- uPVC windows
- Patio & French doors
- Aluminium frames
- Timber windows & doors
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Horsebridge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
