About our mastic sealing in Hunters Forstal

Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on external wall and movement joints, window and door perimeters on blocks and balcony and threshold joints, and the failures we are asked to look at most are the same joint failures repeated across a portfolio and brittle perimeter mastic across a building. One point of contact handles commercial sealant work in Hunters Forstal from the first photos to the final walk-round, whether it’s one building or several.

For buildings around smaller places like Hunters Forstal, we group work so one trip covers it. Photos of each elevation help us quote accurately.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Keep a record of when each building was resealed
  • Check sealant joints during planned building inspections
  • Make it easy for occupiers to report draughts
  • 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.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

When to call us in Hunters Forstal

Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.

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

  • Failed external movement joints
  • Leaks at window and door perimeters
  • Communal area joints that look neglected
  • Brittle perimeter mastic across a building

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

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Failed window or door frames, which need a window contractor

If you are not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

What we seal

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

Common questions from Hunters Forstal clients

Our building in Hunters Forstal is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Do you cover business parks and estates near Hunters Forstal, such as Eddington Business Park?

Yes. We cover Hunters Forstal and the area around it, including industrial estates, business parks and retail parks such as Eddington Business Park. A few photographs and the unit address let us price the work.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

How much does the work cost?

Every job gets its own fixed quote. For yours, call 01277 525 020 or email drawings and photos.

What if the old mastic contains asbestos?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

Do you work in Hunters Forstal?

Yes. Hunters Forstal falls within our area, and you can call 01277 525 020 or send details through our quote form to get started.

How do you reach windows on upper floors?

We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.

Different surfaces, different methods

Planned maintenance

Resealing can be scheduled alongside other planned works on a timetable you set.

Communal areas

We keep entrances and stairs open throughout. Work is planned in sections.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Hunters Forstal need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. A building-by-building inspection lists the failed joints.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint 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.

Getting the site ready

  • Have the specification and drawings to hand
  • Tell us what induction or permit system the site runs
  • Explain the parking and delivery arrangements

Blocks and managed buildings in Hunters Forstal

With the shore within about 2 miles, Hunters Forstal counts as a coastal location. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, so it’s worth inspecting those sides more often. Hunters Forstal sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.

Churches, halls and community buildings such as Church of St Bartholomew are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. For a school such as Herne Church of England Infant School, perimeter mastic on windows and doors is a holiday job.
