Construction mastic for Sarisbury Green sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How we handle construction mastic in Sarisbury Green
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. Sealing too early only means coming back once others have damaged it. If you have internal caulk splitting as the building dries out and existing joints on a refurb that need cutting out and resealing, we can help, on internal decorators’ caulk, brick and block movement joints and floor and skirting junctions alike. A single leaking joint is often how a building in Sarisbury Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
On a small site around Sarisbury Green, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a job in Sarisbury Green, the main thing is a clear picture of the work, so send photos of each area. You will then get a fixed price for the work.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Every joint is prepared, set to depth and sealed with the specified product.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Preparing the site
- Explain the parking and delivery arrangements
- Make sure the joints can be reached
- Share your working hours and any access restrictions

What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Frames fitted out of tolerance
- Designing joint widths or choosing the specification (that sits with the designer)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer.

Questions about Sarisbury Green
Is Sarisbury Green too small for you to travel to?
No. Places such as Sarisbury Green are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Do you cover business parks and estates near Sarisbury Green, such as Park Gate Business Centre?
Yes. Our area takes in Sarisbury Green and its surroundings, with estates and business parks such as Park Gate Business Centre included. Send details of the unit and the work through our quote form for a quick quote.
Can one quote cover more than one building?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can staff carry on working while you are here?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Do you guarantee new-build sealant work?
The work is guaranteed for 12 months. Keeping other trades off finished joints prevents most problems.
How the job changes by surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly.
External facade and movement joints
Many facade substrates need a primer before sealing. We prime where the manufacturer specifies.
Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Note which sealant went where at handover
- Get the mastic subcontractor involved early in the programme
- Stick to the specified sealant rather than a generic substitute
- Keep finished joints away from paint, plaster and scrapers
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work.

Sites and facades in and around Sarisbury Green
Sarisbury Green lies within about 2 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Sarisbury Green included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
New units and refits on sites such as Park Gate Business Centre (1.4 miles north-east of Sarisbury Green) need their panel and perimeter joints sealed to the specification. Hospital estates such as Fareham Community Hospital (0.9 miles north-east of Sarisbury Green) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. When a school such as Sarisbury Infant School is extended or refurbished, the mastic package is often squeezed into the holidays.

Green spaces nearby include Holly Hill Woodland Park.
Why act early in Sarisbury Green
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs. If the frame is life-expired, we will tell you. In a smaller place such as Sarisbury Green, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.
