Mastic sealing for Pagham sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

For owners and agents in Pagham

Pagham lies within about 1 mile of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Pagham is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.

Owners of student blocks near University of Chichester (3.5 miles north of Pagham) can schedule frame and external mastic for the summer vacation. Churches, halls and community buildings such as The Parish Church of St Thomas A Becket are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Pagham is about 3 miles south-west of Bognor Regis, in West Sussex. We cover Pagham and the rest of West Sussex, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 373 places in West Sussex, from busy centres to rural villages. Portsmouth is covered too, around 15 miles from Pagham.

Business premises anywhere in PO21 are within our area. Among the streets we cover are Swan Dene, Sea Lane and Well Road, and sites on any of them can send details for a fixed quote.

How we handle mastic sealing in Pagham

Owners and agents typically inherit a building’s mastic rather than choose it and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. Site teams most often ask us about estate-wide sealant that is simply worn out and damaged joints in communal entrances and corridors, across shopfronts below residential blocks, external wall and movement joints and balcony and threshold joints. Searching for sealant specialists in Pagham? We have been sealing commercial buildings since 2005.

Rural conversions near places like Pagham often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For work around Pagham, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Before we start on site

  • Point out any areas we must not close
  • Warn occupants and staff about the work
  • Send asbestos survey details if the building is pre-2000

Request a quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Related advice

What happens if it’s left?

Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. One visit to deal with every failing joint makes more sense than several trips to a place like Pagham, rather than one at a time. Photos of every joint help us quote for the whole job.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Why appoint us

  • Fully insured, including public liability cover
  • Colours confirmed for the specified product
  • Health and safety: CHAS accredited
  • Fixed quotes based on photos, drawings or a visit

Read our cost guide or our accreditations and insurance.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Avoid piecemeal callouts where you can
  • Ask residents or tenants to report leaks and draughts early
  • Start inspections with the most exposed faces
  • Protect low-level joints in entrances

Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.

Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.

What sets the cost

Before we quote, we look at:

  • Whether the work must be split into stages
  • Backing rod, priming and other preparation
  • Whether old sealant has to be cut out first
  • How accessible the joints are

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Asbestos survey details if the building is older
  • The product your specification calls for
  • Where the site is, with the postcode
  • Anything awkward about access or site hours

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, give us a call on 01277 525 020 or email a schedule or drawings.

What we are called out for in Pagham

Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.

Any of the following is a good reason to get the joints checked over:

  • Open joints in brickwork or panels
  • Damp patches beside frames
  • Occupiers reporting cold air round windows
  • Window mastic that has split and shrunk

If your remit includes a building such as Rose Green Infant School, frame and door mastic can be programmed for the holidays.

What your quote should include

  • The named product and why it was chosen
  • Will RAMS and insurance details be available?
  • What level of public liability insurance do they hold?
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

General trades versus a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Do you work for managing agents and housing associations?

Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.

How do you handle work on occupied blocks?

The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
