Window & door mastic in Nutbourne, West Sussex
Problem with your window and door frames in Nutbourne? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Mastic that has split away from the wall
- Sealant in the wrong colour for the frame
- Whistling draughts around closed windows
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep drainage slots and sill grooves clear
- Repaint timber before it’s bare
- Use gentle cleaners on frames and sealant
- Do not aim a pressure washer at the joints
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
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.
How we handle window mastic in Nutbourne
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you are dealing with cold air getting in at the frame edge and a bead that doesn’t match the frame, we can help.
In a village or hamlet like Nutbourne, 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.
All our work comes with a one-year guarantee.

Do you need window mastic in Nutbourne?
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Signs it’s time to call us include:
- Mastic that’s falling out in pieces
- Gaps where the sill meets the wall
- White mastic on grey or black frames
- Draughty joints inside around the window
For landlords with property near Nutbourne station, renewing tired window mastic between tenants heads off draught and damp complaints.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
If you manage several properties in or around Nutbourne, several properties can go on one quote. Just tell us the addresses and what each one needs.
What affects the quote in Nutbourne
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- Any working-time requirements on site
- Access and height
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- If someone has resealed it before
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved

How it works
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Nutbourne, 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts

Nutbourne homes and the weather
Nutbourne is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around St Wilfrid's Church and Hall, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Chidham Parochial Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Questions from Nutbourne
Is window mastic in a coastal place like Nutbourne any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Nutbourne station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Can I paint over the new sealant?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Do you work in Nutbourne?
Yes, we do. Our applicators work in Nutbourne.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
What the job involves on each surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
