What window mastic looks like in Pested
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Belmont House and Gardens (about 3.4 miles north-west) nearby, there’s older building stock in the area around Pested as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Wye station? Then renewing tired window mastic between tenants heads off draught and damp complaints. If you live in an older home near Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Window mastic in Pested
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you are dealing with draughts coming in around windows and doors and untidy mastic left by window fitters, we can put it right.
In a village or hamlet like Pested, 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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How the job changes by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.

When to call us in Pested
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
The problems people usually mention when they call include:
- Cracked sealant at the sill ends
- Mastic that has split away from the wall
- Gaps left after new windows were fitted
- Cold air getting in at the frame edge
Managing a site like Challock Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- How much experience the applicator has
- Are they insured?
- Which sealant they’ll use, and why
- What guarantee comes with the work

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

What happens on the day
At the end, we look at the finished work together and explain the cure time. The work normally takes most of a day for a typical house, less for a few frames, depending on how much there is to do. In a small place like Pested, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky
- Clear the area around the work

Pested: your questions answered
Is Pested within the area you cover?
Yes. Pested is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Pested for window mastic?

Can I paint over the new sealant?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before work begins.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Honest limits
Before you book, it’s worth knowing the limits too:
- Worn gaskets, brush seals or a door that has dropped
- Condensation trapped between the panes
- Damp coming through the wall itself rather than the frame joint
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
