How we handle construction mastic in Eastleigh
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. We work on brick and block movement joints, cladding and panel joints and internal decorators’ caulk, and the failures we’re asked to look at most are frame gaps too wide for sealant alone and missed perimeter joints on a new elevation. A specialist sealant contractor works differently from a general builder: in Eastleigh, that means joint design, primers and backing rod as standard.
In towns like Eastleigh, sites are usually modest: small housing schemes, extensions to schools and surgeries, refurbished shops and offices. A mastic package on a smaller site still needs the same care at window perimeters and facade joints.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Construction mastic in Eastleigh: the local picture
The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. At about 65 miles from central London, Eastleigh is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
When a school such as Norwood Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. New wings at hospitals like Wessex Hospital, 2.1 miles north of Eastleigh, bring long runs of window and panel joints to seal.

What we’re called out for in Eastleigh
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding, so preparation matters as much here as on a reseal.
Most enquiries start with something like this:
- New external sealant already peeling away
- Sealant knocked or painted over by other trades
- Perimeter gaps outside the sealant’s range
- A mastic package split between trades with no clear owner
For contractors at a college like Eastleigh College - Desborough Campus, 0.6 miles south-west of Eastleigh, perimeters and internal sealant are timed for the holidays.
What your quote should include
- Who will actually carry out the work
- What site paperwork they can supply
- Whether primer will be used where the manufacturer specifies it
- Their plan for phasing and protecting the area
How the quote is worked out
These are the things that shape the price:
- Working within restricted access windows
- Induction, permit and paperwork requirements
- The total length or number of joints
- Backing rod, priming and other preparation
Pricing mastic packages depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
What to include in your enquiry
Whether it’s one area or a whole building, the same details help:
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
- Clear photos of the problem areas
- How the joints are reached, and at what height
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email drawings and photos.

Bathrooms, en suites and washrooms

Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps so we’ll flag where the detail needs something different. Tell us what records you need and we will confirm with the quote.
