Construction mastic for commercial buildings in Hunston
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. That keeps the work right first time and saves rework. If you have cracks opening in caulked internal joints and sealant knocked or painted over by other trades, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hunston, preparation and product choice get the time they need.
Construction in and around smaller places such as Hunston is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Joint design decisions that belong to the architect or engineer
If in doubt, call 01277 525 020 or use the quote form and we will say what we think.

Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a day or two on a small fit-out and several weeks on a large multi-storey package, and we clear our waste as we work. Smaller jobs around Hunston can be grouped with others nearby. You will have a fixed quote before work starts.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Preparing the site
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
- Warn occupants and staff about the work
Getting a fixed quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email drawings and photos.
Advice
Questions we’re asked in Hunston
Can you work on a hospital site such as St Richard's Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work around term dates at a campus such as University of Chichester?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you cover Hunston?
Yes. We take on work across Hunston, with one number for every area we cover.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can you work plot by plot or floor by floor?
The programme sets the job. Tell us the sequence and we’ll plan applicators around it so sealing follows the trades.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Different surfaces, different methods
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent, plot by plot or floor by floor.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team before sealing starts.
Owners, agents and contractors
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.
How the quote is worked out
These are the things that shape the price:
- The size and state of each joint
- Distance, for remote addresses
- Any access equipment needed
- Which sealant the job calls for
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
A few photos plus some basic facts will normally do. It helps to include:
- Specification clauses that apply
- A wide shot and a close-up of the area
- The postcode of the building
- What the building is and how it’s used
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or use the quote form with what you know.
After the work
Once the work is signed off, a little attention goes a long way:
- Allow flexibility for external sealing in damp or cold weather
- Keep finished joints away from paint, plaster and scrapers
- Record the products used in the O&M file
- Ask installers to correct oversized gaps first
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.

What else we do in Hunston
Construction mastic in Hunston: the local picture
Hunston is within about 3 miles of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Hunston lies roughly 56 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.
Extensions at sites like St Richard's Hospital, 2.3 miles to the north of Hunston, usually sit beside working departments, and the mastic follows strict access rules. New units and refits on sites such as City Business Park (to the north of Hunston) need their panel and perimeter joints sealed to the specification. When a college such as West Sussex Alternative Provision College, 0.7 miles east of Hunston, builds or refurbishes, the mastic package normally has to fit around students and staff.
