East Hanney Window Mastic
We cover East Hanney for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Damp patches on the reveal after heavy rain
- Gaps between the frame and the inside reveal
- Untidy mastic left by window fitters
When to call us in East Hanney
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
People normally contact us after spotting one of these:
- Mastic that has split away from the wall
- Leaking joints at the ends of sills
- Draughty joints inside around the window
- Mastic that is falling out in pieces
For an older house near a landmark such as Church of St James, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before you book
- How the colour is chosen
- How long to leave it before use
- Is VAT in the price?
- Whether they’re fully insured
Window mastic in East Hanney
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We are often asked to deal with cracked sealant at the sill ends and draughty joints inside around the window, across uPVC windows, composite doors and patio & French doors.
Outdoor sealant needs dry, clean surfaces, so work on frames around East Hanney is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What affects the quote in East Hanney
Every job gets its own quote. This is what makes a difference:
- Working hours on commercial sites
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- The size of the job
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.
What we need to know
There’s no need for technical detail. Just tell us:
- A few photos by email, if you can
- The address or postcode of the job
- Any previous sealing or DIY work
- The problem you’ve noticed
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved before giving you a price.
Why deal with it now?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around East Hanney can have timber floors and frames, where water from a failed joint can cause rot 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.
Why us?
- Quality sealants from Arbo and Everbuild
- Colour agreed with you before work begins
- We’re fully insured
- Anti-fungal silicone where joints get wet

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Make sure the drainage slots are not blocked
- Paint up to the joint, not over it
- Do not aim a pressure washer at the joints
- Walk round the house once a year and look at the joints
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
Your questions about window mastic in East Hanney
Is window mastic in East Hanney guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Will you come out to East Hanney?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Honest limits
In fairness, there are a few things sealant will not fix:
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
- A sash or casement that won’t close properly

How it works
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work normally takes most of a day for a typical house, less for a few frames. Somewhere like East Hanney 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 look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
How to prepare
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height

Related advice
What window mastic looks like in East Hanney
Historic houses like Longworth House (about 4.5 miles north-west) are a reminder that the area around East Hanney has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as St James Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
