What happens if it’s left?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. Converted and older buildings near places like Marden's Hill tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

How we handle mastic sealing in Marden's Hill
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. We work on external wall and movement joints, window and door perimeters on blocks and communal kitchens and washrooms, and the usual reasons a site gets in touch are estate-wide sealant that is simply worn out and draughts at frames across a block. Looking for mastic applicators who cover Marden's Hill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
For buildings around smaller places like Marden's Hill, we group work so one trip covers it. Send photographs of the frames and joints and we’ll give a fixed quote.
The 12-month guarantee is for workmanship rather than 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.

Your questions answered
Do you work for managing agents with blocks near Crowborough station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
Will you take on work at estates like Crowborough Business Park, close to Marden's Hill?
Yes. Estates, retail parks and business parks around Marden's Hill, Crowborough Business Park among them, are all within reach. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you work with property factors and landlords?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Can you reseal a whole block or estate?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Broken glass or failed sealed units
- Frames that are rotten, warped or broken
- Water coming in from the roof or rainwater goods
If in doubt, call 01277 525 020 or use the quote form and we will say what we think.

Common problems we fix in Marden's Hill
Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one it comes away from one face.
Clients usually get in touch after noticing something like this:
- Open joints in brickwork or panels
- Damaged joints in communal entrances and corridors
- Damp patches beside frames
- Draught complaints from residents or tenants
Older community buildings, St John's Church among them, often have frames of mixed ages whose mastic varies.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
