Construction mastic across Westergate

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Glazing units that are cracked or misted
  • Rework caused by others damaging completed areas
  • Frames fitted out of tolerance

If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Surfaces we seal

  • Brick and block movement joints
  • Internal decorators’ caulk
  • Sanitary and kitchen joints
  • Window and door perimeters
  • Floor and skirting junctions
  • Cladding and panel joints

Construction mastic in Westergate

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. Sealing too early only means coming back once others have damaged it. If you’re dealing with mastic snags holding up handover and sanitary sealant damaged by following trades, we can help, whatever the surface. A single leaking joint is often how a building in Westergate 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.

For a contractor on a smaller site near Westergate, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.

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 spell out the cover before we begin.

How a job runs

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a job in Westergate, the main thing is a clear picture of the work. You will then get a fixed price for the work.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. A fixed quote sets out the scope, the products and the sequence.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. We seal each plot or floor as it’s released to us.
  5. Every joint is prepared, set to depth and sealed with the specified product.
  6. Snags are cleared before handover and completed areas carry our 12-month guarantee.

Preparing the site

  • Warn occupants and staff about the work
  • Arrange parking or a loading space
  • Make sure the joints can be reached

Signs you need construction mastic in Westergate

A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Picking a flexible sealant where there’s movement keeps snags down.

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

  • Perimeter gaps outside the sealant’s range
  • Failed sealant in an existing building being refurbished
  • Missed perimeter joints on a new elevation
  • Mastic snags holding up handover

On a healthcare site such as Bognor Regis War Memorial Hospital, 3.1 miles to the south of Westergate, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Comparing quotes

  • Will RAMS and insurance details be available?
  • Proof of insurance
  • The named product and why it was chosen
  • Who will actually carry out the work

How to choose a sealant contractor

Sites and facades in and around Westergate

The area within 2 miles of Westergate holds a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. At about 52 miles from central London, Westergate is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

With historic properties like Goodwood House (to the north-west of Westergate) in the area, refurbishment work often meets old masonry that needs compatible sealants. School extensions, at buildings such as Aldingbourne Primary School, typically run to the summer holidays, mastic included.

Westergate is about 3 miles north of Bognor Regis, in West Sussex. We cover commercial sites throughout Westergate, for single jobs and planned programmes alike. 373 places across West Sussex fall within our area, including Westergate. We also cover Portsmouth, around 18 miles from Westergate.

Commercial sites across PO20 are covered. For a building on Oaks Close, Westergate Street and Rosvara Avenue or nearby, send details and we will quote for mastic packages. Just outside Westergate, we also work in Nyton (1 mile north-west), Eastergate (1 mile east), Aldingbourne (1 mile west), Norton (1 mile north-west) and West Barnham (1 mile east). Bigger towns within reach include Worthing (12 miles east), Bognor Regis (3 miles south), Chichester (5 miles west), Selsey (9 miles south-west), Littlehampton (6 miles east) and Lancing (15 miles east).

Local landmarks in Westergate

Locally, jobs take us to sites close to Ormiston Six Villages Academy and the streets around them. The closest station to Westergate is Barnham station, about 1.3 miles east. A little further out are Tote Copse Castle (1 mile west) and Bognor Regis War Memorial Hospital (3.1 miles south).

Keeping the joints sound

After handover, a little attention goes a long way:

  • Use the product the specification names
  • Protect sealed areas from following trades
  • Release areas for mastic once other trades have finished in them
  • Keep scrapers and abrasive pads off new beads

Record which products went where in the handover file. That helps the building owner maintain the joints later. Tell us what records you need and we’ll confirm with the quote.

Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out, and avoids a rush.

Questions about Westergate

Can you work at a site such as The Woodhorn Business Centre, by Westergate?

Yes, sites like The Woodhorn Business Centre are within our area, along with the rest of Westergate. A few photos and the unit address let us price the work.

Is a smaller place like Westergate outside your area?

No. Places such as Westergate are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Can you work plot by plot or floor by floor?

We work to your programme. Tell us the sequence and we will plan applicators around it.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your quote.

Can you seal external joints in wet or cold weather?

Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing, so internal areas are often done on those days.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

What affects the price in Westergate

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Phasing around occupants
  • The site’s rules and procedures
  • Access and working height
  • How much existing material needs removing

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

What to include in your enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Where the site is, with the postcode
  • Access details, including height
  • Whether an asbestos survey exists
  • The type of building and who uses it

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email a schedule or drawings to discuss it first.
