Common questions in Adur
Will you come out to Adur?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Shoreham-By-Sea station. Can you help?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Adur and the rest of West Sussex.
Do you seal glass balustrade bases?
Yes, we reseal the joint at the base channel. We don’t install or replace the glass.
Can a conservatory leak be sealed?
Yes, when the leak is a failed sealant joint. If the cause is the roof, a panel or a unit, we’ll say so.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
Is it possible to redo the silicone on a shower screen?
We can. We remove the old silicone carefully, and the joints are cleaned and resealed.
Glazing silicone in Adur, done properly
Glass and frames expand and contract differently, and the silicone between them takes the strain. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. We work on glass balustrade bases, glass-to-glass joints and glass-to-frame joints, and the jobs we see most are water getting into a conservatory at the joints and mouldy sealant around glass panels.
Somewhere as small as Adur, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Windows and doors in Adur
Adur 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 glazing joints and frame seals, which can dry out and crack sooner where a building faces the weather. Historic houses like Portslade Manor (about 3.2 miles east) are a reminder that the area around Adur has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as The Sir Robert Woodard Academy, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Shoreham-By-Sea station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Looking after it afterwards
Looking after new joints is easy:
- Check the silicone on glass every year or so
- Avoid scraping close to the bead
- Act on drips or damp patches early
- Clean glass with a mild cleaner and a soft cloth
Follow the cure time we give you before the joints get wet so the silicone can set properly. After that, clean glass with a mild cleaner.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from an hour or two to most of a day, depending on the size of the job and we leave things clean and tidy. Somewhere like Adur needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
