About our mastic sealing in Netley Marsh
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. If you have damaged joints in communal entrances and corridors and open joints in brickwork or panels, we can put it right, whatever the surface. Most enquiries from Netley Marsh start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Netley Marsh, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Common problems we fix in Netley Marsh
UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.
What tends to prompt an enquiry:
- A mix of products and colours from past repairs
- Draught complaints from residents or tenants
- Communal area joints that look neglected
- No planned programme for sealant
If your remit includes a building such as Netley Marsh Church of England Infant School, frame and door mastic can be programmed for the holidays.
What your quote should include
- Whether old or failed sealant will be cut out, not overlaid
- Is the sealant right for the movement and the substrate?
- Their public liability cover
- Their plan for phasing and protecting the area
What affects the price in Netley Marsh
To price the job, we consider:
- Which sealant the job calls for
- Whether old sealant has to be cut out first
- How much there is to seal
- Whether the work must be split into stages
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What to include in your enquiry
However big the job, these details speed things up:
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
- Approximate linear metres or a joint schedule
- Any specification or named product
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
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 occupiers notice. Halls, stores and units around places like Netley Marsh may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Planned mastic for Netley Marsh portfolios
The sea is no more than about 3 miles from Netley Marsh. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, and they deserve more regular inspection. Rainfall across the South East, Netley Marsh included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.

Questions we’re asked in Netley Marsh
Can you quote for a block close to Ashurst New Forest station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is Netley Marsh too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
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 handle work on occupied blocks?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so it can be arranged.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Aftercare for building managers
For the best life from the joints:
- Make it easy for occupiers to report draughts
- Mention RAMS, insurance or CSCS requirements up front
- Start inspections with the most exposed faces
- Avoid piecemeal callouts where you can
Where a paintable product was specified, it can be painted after curing. Silicone usually can’t be painted, so keep decorators off it.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
Site staff or a sealant specialist?
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
