Window mastic in East Farleigh, done properly
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. Where the air is getting in through the window itself, we’ll say so. We work on aluminium frames, window sills and uPVC windows, and the jobs we see most are cracked or shrunken mastic around the frame and untidy mastic left by window fitters.
Mastic can only go onto a dry, clean joint, so window work in East Farleigh is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Our work is backed for twelve months, in East Farleigh and everywhere else we cover.

What affects the quote in East Farleigh
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The size of the job
- Which sealant suits the joint
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
To make quoting easier, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Any access issues, like height or stairs
- Where the job is, and your postcode
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work.
What happens on the day
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a morning for a couple of windows and a door. Somewhere as small as East Farleigh, access is often the only tricky part. 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.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Mention if the joints have been sealed before
Getting a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Penetrating damp from a failed cavity tray or render
- Rotten timber, which needs a joiner first
- A failed sealed unit that has misted up
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.
Joints and surfaces we work on
- Window sills
- Aluminium frames
- Composite doors
- Patio & French doors
- uPVC windows
- Timber windows & doors
What the job involves on each surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
What window mastic looks like in East Farleigh
With historic houses such as Stoneacre (about 4 miles east) nearby, there’s older building stock in the area around East Farleigh as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.
If you let a flat or house near East Farleigh station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like East Farleigh Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of Saint Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Keep paint and stain on wooden frames in good order
- Paint up to the joint, not over it
- Check the mastic once a year
- Use gentle cleaners on frames and sealant
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
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.
Your questions about window mastic in East Farleigh
Is East Farleigh within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near East Farleigh station. Can you help?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Can new window sealant be painted?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before any work starts.
Do you work on first-floor windows?
Yes, in most cases. We plan safe access before the job.
Is the work guaranteed?
Yes. Our 12-month guarantee covers every job.
How long does it take to reseal the windows on a house?
Allow a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Why it’s worth doing now in East Farleigh
Resealing frames is a short job: it takes a few hours for a handful of frames, longer for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Older cottages and farmhouses around East Farleigh can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
