Window mastic in Piddinghoe, done properly
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you are dealing with cracked or shrunken mastic around the frame and white mastic on grey or black frames, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Piddinghoe is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Your job is guaranteed for a year, as with all our work.

How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Piddinghoe, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- 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.
Getting ready for the visit
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on

Advice
Window mastic in Piddinghoe: local notes
Piddinghoe 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. 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 2.3 miles north) nearby, there’s older building stock in the area around Piddinghoe as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
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. Managing a site like Breakwater Academy? Then its window and door frames need their mastic kept sound, just like a home’s.

Signs you need window mastic in Piddinghoe
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
These are the problems we’re asked about most:
- Draughts coming in around windows and doors
- Rushed sealant from a window installation
- Leaking joints at the ends of sills
- A bead that does not match the frame
In the older streets around The Parish Church of St John, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before you book
- How the surfaces are prepared before sealing
- How long the guarantee is
- What happens if they find a problem under the old sealant
- Who turns up on the day

In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Aftercare tips
A little care helps the new joints last. Our advice:
- Air rooms to keep condensation down around windows
- Do not use solvent cleaners on the joint
- Keep timber frames painted
- Avoid blasting the frames with a pressure washer
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.

FAQs for Piddinghoe
Do you cover smaller places like Piddinghoe?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Newhaven Town station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can I paint over the new sealant?
Not usually, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or email us.
Why deal with it now?
The work is quick compared with the damage it prevents: the visit takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. Around Piddinghoe, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Surface by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
