What the job involves on each surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window mastic for homes and businesses in Ashburnham
Homes in Ashburnham have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have gaps between the frame and the inside reveal and leaking joints at the ends of sills, we can put it right, on patio & French doors, composite doors and uPVC windows alike.
In a village or hamlet like Ashburnham, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Your job is guaranteed for a year, as with all our work.

What else we do in Ashburnham
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Keep paint and stain on wooden frames in good order
- Check the mastic once a year
- Avoid blasting the frames with a pressure washer
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes most of a day for a typical house, less for a few frames. Somewhere like Ashburnham needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Mention any tricky access

Advice
Why it’s worth doing now in Ashburnham
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Ashburnham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Rented homes near Battle station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Parish Church of St Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Questions from Ashburnham
I let a flat near Battle station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Will you come out to Ashburnham?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you have sealant for grey or black windows?
Yes, in most cases. Mention the frame colour when you ask for a quote and we will use the nearest match.

You’ll get a clear quote before we start. It’s based on:
- The size of the job
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- Access and height
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

When something else is needed
