What sand mastic looks like in Kings Worthy
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Winchester station, any sash windows need sound mastic to keep draughts and rain out.

Sand mastic in Kings Worthy, done properly
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. We work on brick reveals, timber door frames and sash and case windows, and the jobs we see most are wind and rain getting in round a sash window and a silicone bead on a sash window that spoils the look.
Around Kings Worthy, 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.
We stand behind the work with a one-year guarantee.

Why act early in Kings Worthy
Filling over old, loose mastic doesn’t last. We remove the loose material first so the new mastic stays put. In a small place like Kings Worthy, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

What we can’t put right

Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint.
People normally contact us after spotting one of these:
- Failed mastic on an exposed elevation
- Mastic dropping out of the joint
- Gaps round a timber door in stone or brick
- Gaps where the frame meets the masonry
Managing a site like Kings Worthy Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

FAQs for Kings Worthy
I let a flat near Winchester station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover Kings Worthy for sand mastic?
Yes, Kings Worthy is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
When will the new mastic be hard?
Not straight away. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
Do you offer different sealant colours?
We help you choose a colour that suits. The product needed can limit the range.
How long does the job take?
A typical job takes a few hours per window, depending on the condition of the joints. We will confirm how long when we quote.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
The process
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Somewhere like Kings Worthy 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 look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Keep children and pets away from the work area
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
