Hemsted: your questions answered
Do you cover smaller places like Hemsted?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Hemsted in your area for window mastic?
Yes, Hemsted is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Does the work come with a guarantee?
Yes, for 12 months. A yearly look at the joints helps them last.
Will resealing my frames help with draughts?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
What sealant do you use?
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 tell you what we are using.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
How we handle window mastic in Hemsted
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on timber windows & doors, window sills and aluminium frames, and people most often call us about cracked sealant at the sill ends and mastic that has split away from the wall.
Outdoor sealant needs dry, clean surfaces, so work on frames around Hemsted is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep drainage slots and sill grooves clear
- Wipe condensation off the frames
- Do not use solvent cleaners on the joint
- Paint up to the joint, not over it
Try not to touch the new joint while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Penetrating damp from a failed cavity tray or render
- A door that needs adjusting, rehanging or new seals
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Frames and glazing around Hemsted
Historic houses like Westenhanger Castle (about 3.1 miles south) are a reminder that the area around Hemsted has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Westenhanger station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as Stowting 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 an older house near a landmark such as Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.

Surface by surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
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.
What happens if it’s left?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we will tell you. Where a wall is exposed, as many are in small places like Hemsted, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes most of a day for a typical house, less for a few frames. In a small place like Hemsted, 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.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
