Mastic sealing for commercial buildings in Burgess Hill

Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. The enquiries we see most involve cracked, hardened mastic round windows on a block and failed external movement joints, across external wall and movement joints, shopfronts below residential blocks and communal entrances and stairwells. Whether you call it commercial sealant work, mastic application or joint sealing, in Burgess Hill it comes down to the same thing: the right product in a properly prepared joint.

In Burgess Hill, as in most towns, a block may have frames from several eras, so mastic around them can be of mixed age and quality. Looking at the whole building first shows what needs doing now and what can wait.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

FAQs: Burgess Hill

Will you take on a block within reach of Burgess Hill station?

Yes, and several blocks can go on one quote. We work to your notice and access arrangements.

Do you work in occupied care homes around Burgess Hill?

Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.

How long does a job like this take?

That varies with the scale of the job, but the work normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we will set out a timescale with the quote.

What paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.

What about access for upper-floor joints?

Every block is different. We agree access with you at quote stage so the fixed quote reflects it.

Can you plan resealing across several buildings?

Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

How the job changes by surface

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.

Window and door perimeters on blocks

Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.

Signs you need mastic sealing in Burgess Hill

Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant, so these repairs rarely last.

If one of these sounds familiar, it’s time for a closer look:

  • Brittle perimeter mastic across a building
  • A mix of products and colours from past repairs
  • Open joints in brickwork or panels
  • Water getting in round frames after rain

If your remit includes a building such as St Wilfrid's Catholic Primary School, frame and door mastic can be programmed for the holidays.

Before you book anyone

  • Their pre-qualification and accreditations
  • Which product they’ll use, and why it suits the joint
  • Do they follow the manufacturer’s priming guidance?
  • Whether old or failed sealant will be cut out, not overlaid

Questions to ask before you appoint anyone

Frames, entrances and external joints in Burgess Hill

Burgess Hill lies roughly 37 miles out from central London. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

Property owners at sites such as Ashwyn Business Centre (to the north-west of Burgess Hill) can have mastic renewed between lettings. Student blocks close to universities like University of Sussex, 4 miles east of Burgess Hill, are easiest to work on between tenancies.

Burgess Hill is about 9 miles north of Brighton, in West Sussex. We cover Burgess Hill, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our West Sussex coverage takes in 373 places, large and small. For work in that direction, see our Brighton page.

Commercial sites across RH15 are covered for mastic joints. Among the streets we cover are Church Road, Station Road and Lower Church Road, and sites on any of them can send details for a fixed quote.

Just outside Burgess Hill, we also work in Jacob's Post (1 mile west), World's End (1 mile north-east), Abbotsford (1 mile north-west), Goddards Green (2 miles west) and Hurst Wickham (2 miles south-west). Bigger towns within reach include Crawley (11 miles north), Horsham (11 miles north-west), Worthing (15 miles south-west), Haywards Heath (3 miles north-east), East Grinstead (13 miles north-east) and Shoreham-by-Sea (10 miles south-west). As one of the bigger centres in West Sussex, Burgess Hill has a broad mix of commercial, public and industrial buildings, and we cover them all.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Misted or failed double-glazed units
  • Leaks through the frame itself rather than the perimeter
  • Leaks from above rather than through a joint

If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Where we work in Burgess Hill

  • Communal kitchens and washrooms
  • Communal entrances and stairwells
  • Window and door perimeters on blocks
  • External wall and movement joints
  • Shopfronts below residential blocks
  • Balcony and threshold joints

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. Town-centre premises in Burgess Hill may have limited parking, so tell us what’s nearby. On estates and business parks it’s usually simpler.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Let building users know which areas are affected
  • Make sure the joints can be reached
