Mastic sealing in Sandhurst Cross

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

After the work

Regular inspection catches problems early. In particular:

  • Make it easy for occupiers to report draughts
  • Log resealing dates block by block
  • Keep bins and bikes away from communal door frames
  • Start inspections with the most exposed faces

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

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.

How we handle mastic sealing in Sandhurst Cross

Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. Site teams most often ask us about damaged joints in communal entrances and corridors and complaints coming in block by block, on external wall and movement joints, shopfronts below residential blocks and communal entrances and stairwells. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Sandhurst Cross, that means joint design, primers and backing rod as standard.

For buildings around smaller places like Sandhurst Cross, we group work so one trip covers it. Send photographs of the frames and joints and we’ll give a fixed quote.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Mastic sealing around Sandhurst Cross: how the place shapes the job

The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building usually need attention first. Central London is about 43 miles from Sandhurst Cross. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.

Schools and community buildings such as Sandhurst Primary School need frame and external mastic kept sound like any building. Historic properties like Great Dixter, 2.5 miles to the south-east of Sandhurst Cross, show the age of some local stock, where frame mastic must suit soft brick or stone.

Sandhurst Cross is about 11 miles north of Hastings, in Kent. If you’re looking for mastic sealing in Sandhurst Cross, we can help, as we do across Kent. 931 places across Kent fall within our area, Sandhurst Cross among them. Brighton is covered too, around 32 miles from Sandhurst Cross.

Commercial sites across TN18 are covered. Among the streets we cover are Church Road, Bodiam Road and Bourne Lane. Close to Sandhurst Cross, our area also takes in Sandhurst (1 mile north-east), Bodiam (1 mile south-west), Little Conghurst (1 mile north-west), Four Throws (1 mile north-west) and Linkhill (2 miles east).

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units 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.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

How the job changes by surface

Commercial and mixed-use buildings

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

Communal areas

Communal areas stay in use while we work. We work in sections so access is never blocked.

What we are called out for in Sandhurst Cross

Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.

These are often picked up first by site or facilities staff:

  • Draught complaints from residents or tenants
  • Brittle perimeter mastic across a building
  • Open joints in brickwork or panels
  • Old repairs sealed over failed mastic

If you own or manage units on a site such as Bodiam Business Park, which lies south-west of Sandhurst Cross, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

How to choose a sealant contractor

Questions we are asked in Sandhurst Cross

Can you quote for a block close to Robertsbridge station?

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

Is Sandhurst Cross too far out for you?

Not at all. Sandhurst Cross is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can people stay in the building while you reseal?

Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so it can be arranged.

Do you guarantee the mastic work?

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

Do you supply RAMS and insurance details?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

How long does a job like this take?

That varies with the scale of the job, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. For work around Sandhurst Cross, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  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. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Preparing the site

  • Point out any areas we must not close
  • Confirm the product named in the specification
  • Arrange parking or a loading space

How the quote is worked out

What shapes the price:

  • Joint width, depth and condition
  • The site’s rules and procedures
  • Which sealant the job calls for
  • Removal of failed or old sealant

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

What to include in your enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours
  • The product your specification calls for
  • The asbestos register, for older buildings

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
