Block-wide mastic in Whitemans Green

The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first. Central London is about 34 miles from Whitemans Green. Within reach of London, blocks run by agents and associations are common around stations.

Site managers at schools like Holy Trinity Church of England Primary School can fit frame mastic into the summer works. Buildings close to stations like Haywards Heath station (1.8 miles south-east of Whitemans Green) are often flats over shops, with frame mastic to keep sound.

About our mastic sealing in Whitemans Green

Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. We work on communal kitchens and washrooms, shopfronts below residential blocks and window and door perimeters on blocks, and the failures we are asked to look at most are communal area joints that look neglected and leaks at window and door perimeters. Looking for mastic applicators who cover Whitemans Green? We’ve been sealing commercial buildings since 2005.

Owners and agents with buildings around smaller places such as Whitemans Green tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

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.

Whitemans Green: questions and answers

Is a smaller place like Whitemans Green outside your area?

Not at all. Whitemans Green is within our area. 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.

Do you work for managing agents with blocks near Haywards Heath station?

Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Can you seal joints high up on a block?

Every block is different. We agree access with you at quote stage so there are no surprises.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

How long does a typical visit take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.

Surface by surface

Commercial and mixed-use buildings

Tenants in commercial buildings need to keep trading, so we plan around them.

Tenement and older buildings

Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

How the quote is worked out

These are the things that shape the price:

  • Distance, for remote addresses
  • Which sealant the job calls for
  • Whether the work must be split into stages
  • Backing rod, priming and other preparation

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • A wide shot and a close-up of the area
  • Asbestos survey details if the building is older
  • Your programme or deadline
  • Rough lengths or quantities, or drawings if you have them

To get a fixed quote, give us a call on 01277 525 020 or send details through our quote form with the site address and an outline of the work. You can also send details through our quote form.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Check the asbestos register before any old mastic is disturbed
  • Encourage occupiers to report problems at frames
  • Include mastic in your cyclical inspections
  • Group repairs into a planned programme

If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.

Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.

Common problems we fix in Whitemans Green

Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Regular cleaning wears them further.

Site and facilities staff are often the first to spot these:

  • Damaged joints in communal entrances and corridors
  • No planned programme for sealant
  • Draughts at frames across a block
  • Damp patches beside frames

Older buildings near Whitemans Green, from historic houses such as Ockenden Manor (to the south of Whitemans Green) to more modest stock, need compatible products when frames are resealed.

  • Their public liability cover
  • Whether primer will be used where the manufacturer specifies it

Choosing a commercial sealant contractor

How a job runs

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Whitemans Green need work, visits can be combined. You will have a fixed quote before work starts.

  1. We inspect each building and record the joints that have failed.
  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.

Preparing the site

  • Confirm the product named in the specification
  • Point out parking and an unloading spot
  • Warn occupants and staff about the work
