Higham homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Temple Manor (about 2.3 miles south-east) nearby, there’s older building stock in the area around Higham 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 is traditional sand mastic.
If you let a flat or house near Higham station, renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Church of St John, the joint between an old wall and a newer frame is usually the first place rain gets in. If you look after a building such as Higham Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Questions from Higham
Can you help a landlord with a rental near Higham station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Can you do window mastic in Higham?
Yes, Higham is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
What should I tell you?
Let us know what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
How long will my window job take?
Allow anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.
Can you get sealant to suit coloured frames?
Usually, yes. Tell us the frame colour when you get in touch and we will use the nearest match.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Why act early in Higham
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Higham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check the mastic once a year
- Wash the frames with mild soapy water
- Keep paint off silicone joints
- Repaint timber before it’s bare
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the amount of work. Somewhere as small as Higham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules

How we quote for window mastic
There’s no set price list, because jobs vary so much. What we look at:
- Any mould that needs treating
- The number of rooms or windows
- The amount of work
- Which sealant suits the joint
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
To help us quote quickly, let us know:
- Pictures of the joints, sent by email
- The rough size of the job
- Whether it has been sealed before
- Any access issues, like height or stairs
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will talk you through the work before giving you a price.
Honest limits
Before you book, it’s worth knowing the limits too:
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp problems in the wall away from the window
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
What we seal
- Window sills
- Patio & French doors
- Composite doors
- uPVC windows

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
