How we handle window mastic in Horsemere Green
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on timber windows & doors, aluminium frames and composite doors, and common reasons people get in touch are rain getting in at the frame or under the sill and mastic that has split away from the wall.
Around Horsemere Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
You get a 12-month guarantee, the same in Horsemere Green as everywhere else we work.

Common questions in Horsemere Green
Does living near the coast affect window mastic in Horsemere Green?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you work for landlords with property near Ford station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
How much does window mastic cost in Horsemere Green?
Size, access and the old material all affect the cost. Call for a quick quote.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Are you insured?
Yes. We are fully insured.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Horsemere Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules

Window mastic in Horsemere Green: local notes
Horsemere Green is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. 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.
If you let a flat or house near Ford station, renewing tired window mastic between tenants heads off draught and damp complaints. Managing a site like St Mary's CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. In the older streets around The Parish Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Around Horsemere Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Paint up to the joint, not over it
- Keep timber frames painted
- Make sure the drainage slots are not blocked
- Avoid blasting the frames with a pressure washer
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
