What affects the price in Elsted Marsh

Before we quote, we look at:

  • Quantities, in metres or numbers
  • Any access equipment needed
  • Location, for remote and island sites
  • Phasing around occupants

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

What we need to price the job

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

  • The asbestos register, for older buildings
  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back
  • Your programme or deadline

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Your questions answered

Do you take on work at healthcare sites like Midhurst Community Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Is a smaller place like Elsted Marsh outside your area?

No. Places such as Elsted Marsh are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Are you insured?

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

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

What joints do you seal on a new build?

Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. We price to the specification and drawings.

Do you offer coloured sealant?

It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Construction mastic in Elsted Marsh: the local picture

Elsted Marsh is about 47 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, Elsted Marsh included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

For a contractor working at a hospital such as Midhurst Community Hospital, which lies east of Elsted Marsh, perimeter and facade sealing is planned around patients and deliveries. When units on a site such as Midhurst Business Centre, 2.6 miles to the east of Elsted Marsh, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Hotels like Southdowns Hotel (1 mile north-west of Elsted Marsh) rarely close for long, so refurbishment mastic is phased floor by floor.

Elsted Marsh is about 6 miles east of Petersfield, in West Sussex. If you’re looking for construction mastic in Elsted Marsh, we can help, as we do across West Sussex. 373 places across West Sussex fall within our area, Elsted Marsh among them.

Looking after the joints

For the best life from the joints:

  • Check frame gaps are within the sealant’s range before sealing
  • Allow flexibility for external sealing in damp or cold weather
  • Use the product the specification names
  • Note which sealant went where at handover

If a joint is damaged after sealing, flag it early. Snags can be picked up in a planned close-out visit, priced as part of the package or separately.

One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating. A check of every frame before decorators start is worth the time.

What happens if it’s left?

Sealing over damaged or contaminated new joints might save a day. Sealant can’t grip a contaminated or existing bead. Damaged joints are removed and resealed from clean faces. Halls, stores and units around places like Elsted Marsh may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

  • Specifying the product where the designer hasn’t
  • Glazing units that are cracked or misted
  • Frame gaps too wide for sealant, which the installer needs to correct

If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

What we seal

  • Window and door perimeters

Advice

How the job changes by surface

External facade and movement joints

External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it.

Internal decorators’ caulk

Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted, and we use a flexible sealant where there’s movement.
