Window mastic for homes and businesses in Burn's Green
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for sealant in the wrong colour for the frame and cracked sealant at the sill ends, on aluminium frames, window sills and uPVC windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Burn's Green is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Your job is guaranteed for a year, as with all our work.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
FAQs for Burn's Green
Is Burn's Green within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Watton-At-Stone station?
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 quote.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months, inside or out.
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Burn's Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear price before we start.

How the visit works
The work is kept neat and contained to the joints we’re treating. The job usually takes a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. For a village or hamlet like Burn's Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Mention any tricky access

Advice
Landlords, agents and businesses in Burn's Green
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What we can’t put right
A few problems are outside what sealant work can do:
- Worn gaskets, brush seals or a door that has dropped
- Faulty window hardware
- Soft or decayed wood in the frame
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Check the mastic once a year
- Repaint timber before it’s bare
- Air rooms to keep condensation down around windows
- Clean frames with a soft cloth and soapy water
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Window mastic in Burn's Green: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Aston Bury (about 2.1 miles west) nearby, there’s older building stock in the area around Burn's Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Parish Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Watton-At-Stone station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like Benington Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
