Advice
Why act early in Cobham
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Small buildings around Cobham suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you are ready.

Questions we’re asked in Cobham
Is a smaller place like Cobham outside your area?
Not at all. Cobham is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Can you work in a care home near Cobham with residents in?
Yes. We work around residents’ routines, a room or two at a time. We follow the home’s own procedures throughout.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Is asbestos a concern with old mastic?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
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.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
General trades versus a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.

- Window mastic that has split and shrunk
- Damaged joints in communal entrances and corridors
- No planned programme for sealant
