About our window mastic in Godshill
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. Typical jobs include sealant in the wrong colour for the frame and water coming in at the bottom corners of a door, on timber windows & doors, uPVC windows and patio & French doors.
Around Godshill, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months.

What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a handful of frames, longer for a whole house. Somewhere like Godshill 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 how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- On commercial sites, let us know about site rules

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Keep timber frames painted
- Clear any debris from frame drain holes
- Avoid harsh chemicals near the mastic
- Do not aim a pressure washer at the joints
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
Honest limits
Before you book, it’s worth knowing the limits too:
- Condensation trapped between the panes
- Soft or decayed wood in the frame
- Worn gaskets, brush seals or a door that has dropped
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.
What we seal

Godshill homes and the weather
Historic houses like Breamore House (about 2.9 miles north-west) are a reminder that the area around Godshill 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near St Giles, 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 The Burgate School and Sixth Form, larger buildings have plenty of frames, and the mastic around each one ages.

Your questions about window mastic in Godshill
Is Godshill within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Godshill in your area for window mastic?
Yes, Godshill is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Is the new sealant paintable?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Tell us if you’re decorating and we will choose accordingly.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you work on first-floor windows?
Yes, if safe access is possible. For high or awkward windows, we will tell you what access is needed.
Why it’s worth doing now in Godshill
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. In a small place like Godshill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.

How we quote for window mastic
Jobs vary more than people expect. What affects the quote:
- Any mould that needs treating
- Access and height
- The type of sealant required
- The size of the job
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Photos by email, if that is easy
- What’s wrong with the joints now
- Where the property is
- Any access issues, like height or stairs
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.
Landlords, agents and businesses in Godshill
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
