Signs you need mastic sealing in High Salvington

We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and it tears.

Clients normally get in touch after noticing one or more of the following:

  • Leaks at window and door perimeters
  • Repeated reactive repairs to the same buildings
  • Patchy repairs in mismatched sealant
  • Brittle perimeter mastic across a building

Blocks of flats and mixed-use buildings often cluster around stations such as Durrington-On-Sea station (to the south of High Salvington) and their window and balcony mastic tends to age at the same rate across a building.

Questions to ask before you book

  • Can the work be phased to keep areas open?
  • Their approach to joint depth and backing
  • Will CSCS-carded applicators be on site?
  • The terms of the workmanship guarantee

Choosing a commercial sealant contractor

Mastic sealing in High Salvington, done properly

Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. If you are dealing with damp patches beside frames and the same joint failures repeated across a portfolio, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in High Salvington, preparation and product choice get the time they need.

Places the size of High Salvington normally have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.

A 12-month guarantee applies to all our work in West Sussex. If an installation problem shows up, phone 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Several jobs near High Salvington can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • For older buildings, check the asbestos register before work

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Reduce knocks to communal area joints
  • Mention RAMS, insurance or CSCS requirements up front
  • Prioritise elevations facing the weather
  • Plan resealing building by building rather than complaint by complaint

Add mastic joints to your cyclical inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.

Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.

Block-wide mastic in High Salvington

High Salvington sits in one of the drier corners of the country, the South East.

If you are responsible for a building such as St Peter, frame and door mastic needs the same attention as any other property. Older buildings near High Salvington, from historic houses such as Ecclesden Manor, 3.1 miles to the south-west of High Salvington, to more modest stock, need compatible products when frames are resealed.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Failed window or door frames, which need a window contractor

  • Broken glass or failed sealed units

Not sure which it is? You can call 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

FAQs: High Salvington

Will you take on work at estates like Gosling Croft Business Centre, close to High Salvington?

Yes, sites like Gosling Croft Business Centre are within our area, along with the rest of High Salvington. To start, just call the office on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is High Salvington too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can you quote from photos?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you send RAMS and CSCS details before starting?

We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
