- Gaps between the frame and the inside reveal
How we handle window mastic in Great Burstead
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you are dealing with rushed sealant from a window installation and damp patches on the reveal after heavy rain, we can help, on uPVC windows, composite doors and patio & French doors alike.
In a village or hamlet like Great Burstead, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a 12-month guarantee.

What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes anything from an hour or two to a full day, depending on how many frames there are in most cases. Somewhere as small as Great Burstead, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.

Frames and glazing around Great Burstead
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 Ingatestone Hall (about 4.6 miles north-west) nearby, there’s older building stock in the area around Great Burstead as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Billericay station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Church of St Mary Magdalene, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Landlord and commercial work in Great Burstead
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
We work for landlords and agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check the mastic once a year
- Keep timber frames painted
- Use gentle cleaners on frames and sealant
- Ventilate rooms so frames don’t stay wet inside
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.

Common questions in Great Burstead
Do you cover smaller places like Great Burstead?
Yes. Great Burstead is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Great Burstead in your area for window mastic?
Yes. We work across London and the South East, and Great Burstead is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Can you do the inside joint as well?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
What does window mastic cost?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Leave it or put it right?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Around Great Burstead, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email.

When to call us in Great Burstead
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
It’s worth asking for a quote if you see:
- Rain getting in at the frame or under the sill
- Draughty joints inside around the window
- Leaking joints at the ends of sills
- Gaps left after new windows were fitted
For site and facilities teams at buildings such as St Peter's Catholic Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- Is VAT in the price?
- What the cure time is
- Which colour the sealant will be
- What product goes in the joint
Different surfaces, different methods
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones are not used, as they can attack some metals. Neutral-cure sealant is the safe choice.
