Mastic sealing around Ashley Heath: points for this area

Rainfall across the South East, Ashley Heath included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.

For a school such as St Ives Primary & Nursery School, perimeter mastic on windows and doors is a holiday job. If you are responsible for a building such as All Saints, frame and door mastic needs the same attention as any other property.

Ashley Heath is in Hampshire. We cover Ashley Heath, with the same fixed quotes and 12-month guarantee as everywhere else. Ashley Heath is one of 723 places we cover in Hampshire. There’s a separate page for Southampton, about 20 miles away.

Mastic sealing for commercial buildings in Ashley Heath

Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow along with complaints. Most enquiries involve brittle perimeter mastic across a building and complaints coming in block by block, on communal kitchens and washrooms, balcony and threshold joints and external wall and movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Ashley Heath it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Places the size of Ashley Heath usually have some housing association stock, small blocks and mixed-use buildings. Their window perimeters and external joints need renewing as the mastic ages.

Our workmanship is guaranteed for 12 months, in Ashley Heath as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Signs you need mastic sealing in Ashley Heath

Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Regular cleaning wears them further.

It’s worth sending us details if you spot any of the following:

  • Damaged joints in communal entrances and corridors
  • Failed external movement joints
  • Water getting in round frames after rain
  • Repeated reactive repairs to the same buildings

If you own or manage units on a site such as Ashley Heath Industrial Estate, which lies north-west of Ashley Heath, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

What your quote should include

  • How long is the guarantee, and what does it include?
  • Their pre-qualification and accreditations
  • Which product they’ll use, and why it suits the joint
  • What site paperwork they can supply

Choosing a commercial sealant contractor

What the job involves on each surface

Planned maintenance

How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.

Tenement and older buildings

Older mastic can contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.

Maintenance after handover

A few simple habits keep the new joints working:

  • Keep a record of when each building was resealed
  • Protect low-level joints in entrances
  • Plan resealing building by building rather than complaint by complaint
  • Mention RAMS, insurance or CSCS requirements up front

Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.

Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.

Common questions from Ashley Heath clients

Will you take on work at estates like Ashley Heath Industrial Estate, close to Ashley Heath?

Yes, sites like Ashley Heath Industrial Estate are within our area, along with the rest of Ashley Heath. Send details of the unit and the work through our quote form for a quick quote.

Do you take on block-wide or estate-wide mastic work in Ashley Heath?

Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

What if the old mastic contains asbestos?

We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you work with property factors and landlords?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

How a job runs

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Several jobs near Ashley Heath can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. First we look at the mastic on each building and note what needs replacing.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Preparing the site

  • Move anything stored against the joints
  • Send your site hours and access windows
  • Point out any areas we must not close

Related advice

Site staff or a sealant specialist?

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.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
