About our mastic sealing in Westdene

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. The enquiries we see most involve draught complaints from residents or tenants and communal area joints that look neglected, across communal entrances and stairwells, balcony and threshold joints and communal kitchens and washrooms. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Westdene, that means joint design, primers and backing rod as standard.

Converted and older buildings in and around Westdene often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Why deal with it now?

A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Quoting for work in Westdene

To price the job, we consider:

  • The size and state of each joint
  • Travel to remote or island sites
  • Whether the work must be split into stages
  • The site’s rules and procedures

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

What to include in your enquiry

We can often quote from photos and a few details. It helps to include:

  • The type of building and who uses it
  • Any dates the work must fit around
  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email drawings and photos.

Questions we are asked in Westdene

Will you take on a block within reach of Preston Park station?

Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.

Can work in a care setting near Westdene go ahead while residents are there?

Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

What if the old mastic contains asbestos?

Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Can you reseal a whole block or estate?

Block-wide and estate programmes are common. The quote can be split however suits your budgeting.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Have the asbestos survey to hand for older buildings
  • Look at the sunniest and most exposed elevations first
  • Plan resealing building by building rather than complaint by complaint
  • Encourage occupiers to report problems at frames

Keep records of when each building was resealed. It helps plan the next round and shows what was done.

Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. For a job in Westdene, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.

Blocks and managed buildings in Westdene

With the shore within about 3 miles, Westdene counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.

Owners of student blocks near University of Brighton Moulesecoomb Campus (2.1 miles south-east of Westdene) can schedule frame and external mastic for the summer vacation. Property owners at sites such as Goldstone Retail Park (to the south of Westdene) can have mastic renewed between lettings. If you look after a block within reach of Preston Park station, which lies south of Westdene, frame and balcony mastic can be renewed on one programme.
