Window mastic for homes and businesses in Hollingdean
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. Typical jobs include whistling draughts around closed windows and leaking joints at the ends of sills, on aluminium frames, uPVC windows and timber windows & doors.
In smaller places like Hollingdean, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Do you need window mastic in Hollingdean?
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That’s what backing rod is for.
Any of these means the joints need attention:
- Cracked sealant at the sill ends
- Damp patches on the reveal after heavy rain
- Draughty joints inside around the window
- Black, perished sealant on frames
For landlords with property near Moulsecoomb station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Your questions about window mastic in Hollingdean
Will you come out to Hollingdean?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Moulsecoomb station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Are you insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can new window sealant be painted?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Looking after it afterwards
After the cure time, these simple habits help:
- Wash the frames with mild soapy water
- Keep solvents and bleach off the sealant
- Wipe condensation off the frames
- Avoid blasting the frames with a pressure washer
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes anything from an hour or two to a full day, depending on how many frames there are from start to finish. A visit to Hollingdean is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in

What else we do in Hollingdean
Window mastic in Hollingdean: local notes
Hollingdean is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Preston Manor & Gardens (about 0.9 miles west) are a reminder that the area around Hollingdean has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For site and facilities teams at buildings such as Hertford Infant and Nursery School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Richard's, the joint between an old wall and a newer frame is generally the first place rain gets in.

Different surfaces, different methods
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.
What sealant work can’t fix
In fairness, there are a few things sealant won’t fix:
- A frame that has rotted at the joint
- Faulty window hardware
- A door that needs adjusting, rehanging or new seals
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.
