Window mastic in Filchampstead
Around Filchampstead we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you are dealing with cracked sealant at the sill ends and cracked or shrunken mastic around the frame, we can help.
Mastic can only go onto a dry, clean joint, so window work in Filchampstead is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A one-year guarantee comes as standard.

Aftercare tips
A little care helps the new joints last. We recommend:
- Don’t paint over the silicone
- Use gentle cleaners on frames and sealant
- Keep drainage slots and sill grooves clear
- Keep paint and stain on wooden frames in good order
Timber frames need their paint kept up, 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 it pays to reseal before that happens.
What the job involves on each surface
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Composite doors
Front doors take the weather head on. We pay most attention there.
How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes most of a day for a typical house, less for a few frames. In a small place like Filchampstead, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height

Related advice
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Filchampstead questions
Is Filchampstead within the area you cover?
Yes, Filchampstead is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Filchampstead for window mastic?
Yes, Filchampstead is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Can I paint over the new sealant?
Most silicone can’t be painted. Let us know beforehand, and we will use a paintable product where it suits.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Is the work guaranteed?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
Do you work for landlords and businesses?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.

We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- A sash or casement that will not close properly
- A failed sealed unit that has misted up
- A frame that has rotted at the joint
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Filchampstead 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 Appleton Manor (about 2.8 miles south) are a reminder that the area around Filchampstead 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.
Rented homes near Oxford station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as St Mary's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Schools such as Cumnor Church of England School (Voluntary Controlled) are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
