New build and refits around Hunston

Hunston is within about 3 miles of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. At about 56 miles from central London, Hunston is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

Recladding or extending a unit at a site like City Business Park, 1.5 miles to the north of Hunston, brings panel joints and frame perimeters into the programme. Hospital estates such as St Richard's Hospital, 2.3 miles north of Hunston, 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.

Hunston is about 2 miles south of Chichester, in West Sussex. Businesses, contractors and managing agents in Hunston use us for work on facade joints. Hunston is one of 373 places in West Sussex on our list for facade joints. For work in that direction, see our Portsmouth page.

Facade sealing in Hunston

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. If you have weathered joints at frame-to-structure perimeters and leaks at window and door perimeters, we can help, on coping and flashing joints, shopfront frames and cladding panel joints alike. A specialist sealant contractor works differently from a general builder: in Hunston, that means joint design, primers and backing rod as standard.

Sites around smaller places like Hunston can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we’ll quote to suit.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What sealant work can’t fix

Some faults sit outside our scope, and we say so rather than covering them up:

  • Installing or repairing glazing systems
  • Specialist high-level access methods
  • Joints whose design needs changing by the specifier

If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints and surfaces we work on

  • Window and door perimeters
  • Stone and brick facade joints
  • Coping and flashing joints
  • Cladding panel joints
  • Shopfront frames
  • Perimeter joints where frames meet the structure

FAQs: Hunston

Can you work around term dates at a campus such as University of Chichester?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Does your area include sites such as City Business Park, near Hunston?

Yes, sites like City Business Park are within our area, along with the rest of Hunston. Send details of the unit and the work through our quote form for a quick quote.

Is it okay to overlay old mastic?

No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

What type of sealant goes on window perimeters?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

Maintenance after handover

Cleaning and maintenance staff play a part too. Share these points with them:

  • Add perimeter sealant to planned maintenance checks
  • Brief window cleaners about newly sealed joints
  • Insist on a full cut-out when joints are renewed
  • Keep the sealant details on the building file

Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness.

Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading behind the facade.

Leave it or put it right?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Around Hunston, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Hunston may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Point out parking and an unloading spot
  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Do you need facade sealing in Hunston?

Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.

It’s worth sending us details if you spot any of the following:

  • Failed sealant on precast panel joints
  • Cold air coming in at window perimeters
  • Water coming in around window frames
  • Sealant pulling away from frames or panels

Hotels like Crouchers Hotel (to the west of Hunston) rarely close for long, so refurbishment mastic is phased floor by floor.

What your quote should include

  • Proof of insurance
  • Do they follow the manufacturer’s priming guidance?
  • Their pre-qualification and accreditations
  • Which product they’ll use, and why it suits the joint
