How we handle window mastic in Horndon on the Hill
Around Horndon on the Hill we seal all kinds of frames: 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 work on composite doors, aluminium frames and timber windows & doors, and common reasons people get in touch are draughts coming in around windows and doors and draughty joints inside around the window.
In a village or hamlet like Horndon on the Hill, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

Signs you need window mastic in Horndon on the Hill
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Any of these means the joints need attention:
- Mastic that has split away from the wall
- Sealant in the wrong colour for the frame
- Mastic that is falling out in pieces
- Water coming in at the bottom corners of a door
In the older streets around Church of St Peter and St Paul, the joint between an old wall and a newer frame is normally the first place rain gets in.

Window mastic in Horndon on the Hill: local notes
Horndon on the Hill is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

What we do, step by step
On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before we start. Most jobs take most of a day for a typical house, less for a few frames. Somewhere as small as Horndon on the Hill, access is often the only tricky part. 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, 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
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What the job involves on each surface
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall.
How we quote for window mastic
Every job gets its own quote. These are the things that affect it:
- The number and length of the joints
- Which sealant suits the joint
- How many areas need sealing
- Whether the work is at height
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Where the job is, and your postcode
- A few pictures by email, if you can

Can you help a landlord with a rental near Stanford-Le-Hope station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Does the coastal weather in Horndon on the Hill affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you work in Horndon on the Hill?
We do. Our applicators work in Horndon on the Hill, and the service is the same as everywhere else.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Do you work on first-floor windows?
Yes, if safe access is possible. For high or awkward windows, we’ll tell you what access is needed.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you get sealant to suit coloured frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
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.
