About our mastic sealing in Marsh Green
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you’re dealing with failed external movement joints and window mastic that has split and shrunk, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Marsh Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Marsh Green, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Aftercare for building managers
For the best life from the joints:
- Check the asbestos register before any old mastic is disturbed
- Make mastic part of routine maintenance checks
- Keep a record of when each building was resealed
- Avoid piecemeal callouts where you can
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
Cost factors for mastic joints
Quotes vary with the job. It mainly depends on:
- Which sealant the job calls for
- Induction, permit and paperwork requirements
- Any access equipment needed
- Location, for remote and island sites
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
What we need to price the job
However big the job, these details speed things up:
- What the building is and how it’s used
- Any dates the work must fit around
- The product your specification calls for
- Photos of the joints, close up and from further back
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
Common questions from Marsh Green clients
Will you price a mastic programme across our Marsh Green portfolio?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Our building in Marsh Green is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.
Is Marsh Green in your area?
Yes. Marsh Green falls within our area, and the simplest way to start is to ring 01277 525 020 or send details through our quote form.
Do you work for managing agents and housing associations?
We do. 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.
Does weather matter for sealant 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.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Glazing that needs replacing
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a day or two for a single block, longer for an estate programme, and our waste is bagged and taken away as we go. If others near Marsh Green need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- We strip out the old sealant.

Before we start on site

Related advice
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Marsh Green can form part of a wider programme.
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
For owners and agents in Marsh Green
Marsh Green lies within about 1 mile of the sea. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do. The South East is one of the drier parts of the UK. 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.
Older community buildings, St. Mary's Church among them, often have frames of mixed ages whose mastic varies. Older buildings near Marsh Green, from historic houses such as Mottistone Manor (to the north-west of Marsh Green) to more modest stock, need compatible products when frames are resealed. Site managers at schools like Brighstone Church of England Aided Primary School can fit frame mastic into the summer works.
