Window mastic in Watton at Stone, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. We work on uPVC windows, timber windows & doors and patio & French doors, and common reasons people get in touch are mastic that has split away from the wall and gaps between the frame and the inside reveal.
Somewhere as small as Watton at Stone, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months, in Watton at Stone and everywhere else we cover.

Watton at Stone: your questions answered
I let a flat near Watton-At-Stone station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Do you cover smaller places like Watton at Stone?
Yes, Watton at Stone is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months, inside or out.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Surface 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.
Composite doors
An exposed front door gets wind-driven rain. We pay most attention there.
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a morning for a couple of windows and a door, and the area is left clean. Somewhere like Watton at Stone needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Keep children and pets away from the work area

Aftercare tips
So the new joints stay in good condition:
- Look round the frames every year or so
- Avoid harsh chemicals near the mastic
- Wipe condensation off the frames
- Clean frames with a soft cloth and soapy water
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Rotten timber, which needs a joiner first
- Broken hinges, locks or handles
- A failed sealed unit that has misted up
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Aluminium frames
- Window sills
- Composite doors
- Patio & French doors
- Timber windows & doors
- uPVC windows
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Why it’s worth doing now in Watton at Stone
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In a small place like Watton at Stone, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear price before any work starts.
What you get with us
- Anti-fungal silicone where joints get wet
- You choose the colour before work begins
- Arbo and Everbuild products
- Over 20 years’ experience

Frames and glazing around Watton at Stone
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Aston Bury (about 2 miles north-west) are a reminder that the area around Watton at Stone 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.
In the older streets around Church of St Andrew and St Mary, the joint between an old wall and a newer frame is generally the first place rain gets in. For site and facilities teams at buildings such as Watton-at-Stone Primary and Nursery School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Watton-At-Stone station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
