Windows and doors in Farleigh
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 Addington Palace (about 2.2 miles north) are a reminder that the area around Farleigh 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.
For landlords with property near Upper Warlingham station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Church of St Mary the Virgin include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Farleigh questions
Do you cover smaller places like Farleigh?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Farleigh in your area for window mastic?
Yes. We work across London and the South East, and Farleigh is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we will choose accordingly.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can you do upstairs windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
Can you quote for more than one area?
Yes. Just list everything you need and you will get one quote.
Signs you need window mastic in Farleigh
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Look out for any of the following:
- Mastic that has split away from the wall
- White mastic on grey or black frames
- Gaps left after new windows were fitted
- Water coming in at the bottom corners of a door
Schools such as Meridian High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first
- A failed sealed unit that has misted up
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

How the visit works
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. In a small place like Farleigh, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
