How we handle mastic sealing in Wisborough Green

For blocks and buildings in Wisborough Green and across West Sussex, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. Site teams most often ask us about the same joint failures repeated across a portfolio and communal area joints that look neglected, across balcony and threshold joints, communal kitchens and washrooms and communal entrances and stairwells. Whoever orders the work in Wisborough Green, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Owners and agents with buildings around smaller places such as Wisborough 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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Blocks and managed buildings in Wisborough Green

Wisborough Green is about 37 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Rainfall across the South East, Wisborough Green included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

If you own or manage units on a site such as Gillman's Industrial Estate, which lies east of Wisborough Green, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Blocks of flats and mixed-use buildings often cluster around stations such as Billingshurst station, 2.5 miles east of Wisborough Green, and their window and balcony mastic tends to age at the same rate across a building. Churches, halls and community buildings such as The Parish Church of St Peter Ad Vincula are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Wisborough Green need work, visits can be combined. A fixed quote is given before anything starts.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Getting the site ready

  • Flag any permit to work we will need
  • Move anything stored against the joints
  • Send asbestos survey details if the building is pre-2000

Request a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Different surfaces, different methods

Tenement and older buildings

Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.

Planned maintenance

Adding mastic to planned maintenance avoids reactive repairs and keeps budgets predictable.

Building owners, agents and FMs in Wisborough Green

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Looking after the joints

For the best life from the joints:

  • Start inspections with the most exposed faces
  • Mention RAMS, insurance or CSCS requirements up front
  • Ask residents or tenants to report leaks and draughts early
  • Check sealant joints during planned building inspections

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.

One failed perimeter normally means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Asbestos-containing sealant, which we don’t remove
  • Leaks through the frame itself rather than the perimeter
  • Broken glass or failed sealed units

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Joints and surfaces we work on

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

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you cover business parks and estates near Wisborough Green, such as Gillman's Industrial Estate?

Can you plan resealing across several buildings?

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

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Can you take on resealing for a block portfolio?

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

Do you work to architects’ specifications?

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
