Mastic sealing for commercial buildings in Southover
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn.

Do you need mastic sealing in Southover?
Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
Look out for the following:
- Draughts at frames across a block
- Mastic failing across several blocks on an estate
- Movement joints with sealant missing
- Patchy repairs in mismatched sealant
Owners of student blocks near University of Sussex, 4.2 miles to the west of Southover, can schedule frame and external mastic for the summer vacation.
Questions to ask before you book
- Will failed sealant be removed rather than covered?
- How the joint faces will be prepared and primed
- Which product they’ll use, and why it suits the joint
- Who will actually carry out the work
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Keeping the joints sound
After handover, these steps help:
- Ask residents or tenants to report leaks and draughts early
- Share your contractor requirements early
- Reduce knocks to communal area joints
- Keep a record of when each building was resealed
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

What else we do in Southover
Leave it or put it right?
Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

FAQs: Southover
Do you cover business parks and estates near Southover, such as Phoenix Industrial Estate?
Yes, sites like Phoenix Industrial Estate are within our area, along with the rest of Southover. Send details of the unit and the work through our quote form for a quick quote.
Is Southover too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Advice
Mastic sealing around Southover: how the place shapes the job
Southover lies roughly 44 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Southover sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
Buildings close to stations like Lewes station (less than half a mile east of Southover) are often flats over shops, with frame mastic to keep sound. If your remit includes a building such as Western Road Community Primary School, frame and door mastic can be programmed for the holidays.
