How the job changes by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Window mastic in Tillington
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on aluminium frames, timber windows & doors and patio & French doors, and people most often call us about mastic that has split away from the wall and sealant in the wrong colour for the frame.
Mastic can only go onto a dry, clean joint, so window work in Tillington is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Faulty window hardware
- Rotten timber, which needs a joiner first
- A failed sealed unit that has misted up

DIY sealant or a professional job?
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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Signs you need window mastic in Tillington
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. That is what backing rod is for.
Any of these means the joints need attention:
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
- Cracked sealant at the sill ends
- Mastic that has split away from the wall
Schools such as Petworth Cof E Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- What product goes in the joint
- How the colour is chosen
- What the cure time is
- Is the old sealant removed completely?
Tillington: your questions answered
Is Tillington in your area for window mastic?
Yes, Tillington is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.
Is window mastic in Tillington guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can you do upstairs windows?
Usually, yes. We plan safe access before the job, so mention the height and anything in the way.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
How much does window mastic cost in Tillington?
Size, access and the old material all affect the cost. Call for a quick quote.
Aftercare tips
A little care helps the new joints last. We recommend:
- Check the mastic once a year
- Ventilate rooms so frames do not stay wet inside
- Wash the frames with mild soapy water
- Paint up to the joint, not over it
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.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
How it works
On the day, we look over the joints with you first. Surfaces next to the work are protected 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 Tillington, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
Ask for a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

What else we do in Tillington
What window mastic looks like in Tillington
With historic houses such as Petworth House (about 0.8 miles east) nearby, there’s older building stock in the area around Tillington as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near The Parish Church of All Hallows, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
