About our window mastic in Small Hythe
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We are often asked to deal with gaps where the sill meets the wall and gaps left after new windows were fitted, across window sills, uPVC windows and timber windows & doors.
Mastic can only go onto a dry, clean joint, so window work in Small Hythe is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee.

How the job changes by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Window sills
Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.

What we need to know
Photos by email are helpful but not essential. Please mention:

What happens on the day
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Small Hythe, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on

Landlord and commercial work in Small Hythe
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
How to look after the new joints
To keep the joints looking good and working properly:
- Wipe condensation off the frames
- Don’t aim a pressure washer at the joints
- Clear any debris from frame drain holes
- Wash the frames with mild soapy water
Most silicone sealants will not take paint, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Small Hythe homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Smallhythe Place (about 0.2 miles south) are a reminder that the area around Small Hythe has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Homewood School and Sixth Form Centre? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St John the Baptist include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

Why it’s worth doing now in Small Hythe
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Where a wall is exposed, as many are in small places like Small Hythe, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us.

Questions from Small Hythe
Do you cover smaller places like Small Hythe?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is window mastic in Small Hythe guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Where are you based?
Mr Mastic is based in Crawley. We cover Small Hythe and the rest of Kent, along with the rest of our area.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Can landlords and businesses book you?
Yes. We work in homes, commercial premises and hotels, and we’re fully insured.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
