How it works
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes most of a day for a typical house, less for a few frames. Parking around Telscombe Cliffs 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.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- Clear items away from the joints we are working on

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Frames and glazing around Telscombe Cliffs
Telscombe Cliffs is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Monk's House (about 3 miles north-east) nearby, there’s older building stock in the area around Telscombe Cliffs 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.
If you look after a building such as Telscombe Cliffs Community Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Ascension Church, the joint between an old wall and a newer frame is usually the first place rain gets in. Letting a property close to Newhaven Town station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

FAQs for Telscombe Cliffs
Do you cover smaller places like Telscombe Cliffs?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does the coastal weather in Telscombe Cliffs affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Is the work guaranteed?
Yes. Our 12-month guarantee covers every job, inside or out.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
What affects the quote in Telscombe Cliffs
The quote reflects the job in front of us. We look at:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- Which sealant suits the joint
- The size of the job
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before any work starts.
What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
If you’re in Telscombe Cliffs and need window mastic, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you’ll get a clear quote before we start.
Why deal with it now?
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. In a smaller place like Telscombe Cliffs, 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.

How the job changes by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Repaint timber before it’s bare
- Clear any debris from frame drain holes
- Wipe condensation off the frames
- Walk round the house once a year and look at the joints
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
