Facade sealing in Warsash, done properly
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. We work on cladding panel joints, shopfront frames and window and door perimeters, and the failures we’re asked to look at most are perimeter joints where frames meet the structure and weathered facade joints that have lost their grip. Looking for mastic applicators who cover Warsash? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
For a contractor on a smaller site near Warsash, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Aftercare for building managers
To get the most from the new sealant:
- Ask about asbestos in pre-2000 mastic
- Share access with other external trades
- Brief window cleaners about newly sealed joints
- Report water ingress at frames as soon as it shows
Keep a note of which product went in and when. Future work can then match the product and colour across the elevation.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.
Your questions answered
Is a smaller place like Warsash outside your area?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Would you work within a site like Fareham Community Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will rain stop the work?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, and we build that into the programme.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you run new sealant over the existing bead?
No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.
What we’re called out for in Warsash
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained and tears as the joint moves.
Site and facilities staff are often the first to spot these:
- Cold air coming in at window perimeters
- Old perimeter mastic that has dried out
- Gaps between rainscreen or cladding panels
- Discoloured or dirty facade joints
Projects at schools like Hook-With-Warsash Church of England Academy work to term dates, so mastic is programmed tightly.
Questions to ask before you book
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
- The named product and why it was chosen
- What site paperwork they can supply

Why it’s worth doing now in Warsash
Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Installing or repairing glazing systems
- Joints too narrow for the movement they take, which need redesign
- Cracked or spalling substrates that need repair before sealing
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think before you book.
What we seal
- Stone and brick facade joints

Contractors’ notes for Warsash
Warsash sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. Warsash is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.
New units and refits on sites such as Park Gate Business Centre (1.7 miles north-east of Warsash) need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as Fareham Community Hospital, 1.1 miles north-east of Warsash, perimeter and facade sealing is planned around patients and deliveries.

- Both faces are cleaned and, where the product needs it, primed.
