Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Brief cleaning contractors to avoid scourers and blades on sealant
- Keep washroom and kitchen extraction working
- Ask fit-out and M&E contractors to report any sealant they disturb
- Keep a record of which joints were resealed and when
Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, with external elevations and wet areas first in line. Should something look amiss, you can ring 01277 525 020 or send photos by email and send a picture.
Sealant rarely fails all at once across a building. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.
Commercial mastic work in Southcourt
Sealant joints are easy to overlook until one lets water in, and in an occupied building failure typically announces itself as a stained ceiling or an unhappy tenant. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors with sites in Southcourt. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. Most enquiries involve hardened, chalky sealant on south-facing or exposed elevations and shrunken sealant along kitchen worktops and splashbacks, across kitchen worktops and splashbacks, external facade joints and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Southcourt, preparation and product choice get the time they need.
The most common commercial job in Southcourt is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
Small businesses near places like Southcourt frequently occupy converted farm buildings. Old masonry and timber meet new glazing and partitions in these buildings, and every junction needs a sealant that suits it.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Southcourt: questions and answers
Do hotels near Southcourt have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.
Is a smaller place like Southcourt outside your area?
No. Places such as Southcourt are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can you take on work for an FM or managing agent?
Yes. You send the details, we return a fixed quote, and the job is done and signed off.
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.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Could the old sealant in an older building contain asbestos?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.
Can you handle sealant work across several sites?
Yes, we can. Give us the sites and the scope at each, and fixed prices follow, with a suggested sequence.
Why deal with it now?
Patching the worst lengths can be the right call on a tight budget. Where the remaining sealant is just as old, it tends to fail soon after, so access and set-up end up being paid for twice. Where it helps, we quote a patch and a full reseal side by side. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

When to call us in Southcourt
If only one face has lost its grip, that’s an adhesion failure. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.
It’s worth sending us details if you spot any of the following:
- Frame sealant that has cracked, shrunk or pulled away
- Greasy, split joints in a kitchen or tea point
- Movement joints packed with grit and debris
- Earlier reseals applied straight onto the failed bead
Offices at parks like Fountain Business Centre, 1 mile to the south-east of Southcourt, have receptions, kitchens and glazed partitions where a tidy joint matters.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- How the joint faces will be prepared and primed
- Can the work be phased to keep areas open?
- Are they CHAS accredited or on Constructionline?
When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Structural cracks or movement the joints weren’t designed for
- Old mastic that tests positive for asbestos
- Roof leaks that only look like a joint problem
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly.
