Window mastic in Little Kingshill, done properly
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on patio & French doors, composite doors and aluminium frames, and common reasons people get in touch are untidy mastic left by window fitters and leaking joints at the ends of sills.
Mastic can only go onto a dry, clean joint, so window work in Little Kingshill is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee.

Common questions in Little Kingshill
Can you help a landlord with a rental near Great Missenden station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Little Kingshill?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
How many windows can you do in a day?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
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.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Little Kingshill homes and the weather
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Hughenden Manor (about 3.5 miles south-west) are a reminder that the area around Little Kingshill 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.
Homes close to Church of Saints Peter and Paul include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Ash Hill Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. Neutral-cure sealant is the safe choice.
Do you need window mastic in Little Kingshill?
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Hard, cracked sealant around windows
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
- Gaps left after new windows were fitted
If you let a flat or house near Great Missenden station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Aftercare tips
After the cure time, these simple habits help:
- Keep timber frames painted
- Walk round the house once a year and look at the joints
- Avoid blasting the frames with a pressure washer
- Ventilate rooms so frames do not stay wet inside
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
What we cannot put right
It helps to know what we cannot do:
- Broken hinges, locks or handles
- Condensation trapped between the panes
- Worn gaskets, brush seals or a door that has dropped
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before you book.
