Window mastic in Hawkhurst
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for rain getting in at the frame or under the sill and sealant in the wrong colour for the frame, across timber windows & doors, composite doors and uPVC windows.
Around Hawkhurst, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What affects the cost of window mastic
Your quote is based on your job. We look at:
- Which sealant suits the joint
- Any mould that needs treating
- The size of the job
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.

Other services in Hawkhurst
What we’re called out for in Hawkhurst
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
People generally contact us when they notice one of these:
- Gaps between the frame and the inside reveal
- Cracked sealant at the sill ends
- White mastic on grey or black frames
- Whistling draughts around closed windows
If you live in an older home near Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- How much experience the applicator has
- What the quote includes, VAT included or not
- How hidden problems are handled
- Whether they seal over old material or remove it
How the visit works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It normally takes anything from an hour or two to a full day, depending on how many frames there are. Parking around Hawkhurst is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on

Common questions in Hawkhurst
Do you cover Hawkhurst for window mastic?
Yes. Our work covers London and the South East, and Hawkhurst is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
I let a flat near Etchingham station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Is the new sealant paintable?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before work begins.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We check where the draught is before we start.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
What happens if it’s left?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a smaller place like Hawkhurst, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Surface by surface
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
Window mastic in Hawkhurst: 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 Great Dixter (about 5 miles south-east) nearby, there’s older building stock in the area around Hawkhurst as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Hawkhurst Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Etchingham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Looking after it afterwards
Aftercare is simple:
- Paint up to the joint, not over it
- Keep jet washers away from the mastic
- Check the mastic once a year
- Don’t use solvent cleaners on the joint
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
