How the job changes by surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets 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.
How we handle window mastic in Hempton
Homes in Hempton have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We’re often asked to deal with draughts coming in around windows and doors and black, perished sealant on frames, on window sills, timber windows & doors and patio & French doors.
In a village or hamlet like Hempton, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Frames and glazing around Hempton
Historic houses like Broughton Castle (about 4.3 miles north-west) are a reminder that the area around Hempton 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 is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Saint John the Evangelist, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY versus a professional finish
If you are set on DIY, put the effort into 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.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Do you need window mastic in Hempton?
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
It’s worth asking for a quote if you see:
- Leaking joints at the ends of sills
- Hard, cracked sealant around windows
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
If you let a flat or house near Kings Sutton station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Your questions about window mastic in Hempton
Can you help a landlord with a rental near Kings Sutton station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Is Hempton within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you when we finish.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Are you insured?
Yes. We’re fully insured.
The process
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we explain the cure time before we leave. Somewhere as small as Hempton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children

Advice
Why act early in Hempton
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Hempton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- Anti-fungal silicone where joints get wet
- We leave the area clean and tidy
- You choose the colour before work begins
- An ARBOMaster approved applicator

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Walk round the house once a year and look at the joints
- Repaint timber before it’s bare
- Make sure the drainage slots aren’t blocked
- Wash the frames with mild soapy water
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
