Mastic packages on Laverstoke sites

Laverstoke is about 55 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. Laverstoke is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

Projects at schools like Testbourne Community School work to term dates, so mastic is programmed tightly.

How we handle facade sealing in Laverstoke

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. The enquiries we see most involve gaps between rainscreen or cladding panels and perimeter sealant that has split or peeled away, on perimeter joints where frames meet the structure, shopfront frames and coping and flashing joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Laverstoke, preparation and product choice get the time they need.

Construction in and around smaller places such as Laverstoke is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

A short, simple internal joint is often within reach of a maintenance team. 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.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Avoid harsh cleaners on facade sealant
  • Report water ingress at frames as soon as it shows
  • Plan facade sealing alongside redecoration
  • Add perimeter sealant to planned maintenance checks

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade instead of soaking the joints.

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Laverstoke: questions and answers

Will you take on work at estates like Ardglen Industrial Estate, close to Laverstoke?

Yes. Our area takes in Laverstoke and its surroundings, with estates and business parks such as Ardglen Industrial Estate included. A few photos and the unit address let us price the work.

Is Laverstoke too far out for you?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Laverstoke are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand

How the job changes by surface

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Perimeter joints at frames and structure

Perimeter joints at frames often show their age first. They are cut out, cleaned, backed and resealed.

Common problems we fix in Laverstoke

Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.

Look out for the following:

  • Sealant pulling away from frames or panels
  • Draughts around frames and panels
  • Patch repairs that keep failing
  • Cladding panel joints that have opened up

New units and refits on sites such as Ardglen Industrial Estate, 1.9 miles west of Laverstoke, need their panel and perimeter joints sealed to the specification.

Questions to ask before you book

  • Are they CHAS accredited or on Constructionline?
  • Whether primer will be used where the manufacturer specifies it
  • How they’ll work around occupants
  • Their public liability cover
