Mastic sealing in Horseport, done properly

In buildings from before 2000, some old mastics contain 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 communal kitchens and washrooms, external wall and movement joints and communal entrances and stairwells, and the usual reasons a site gets in touch are repeated reactive repairs to the same buildings and water getting in round frames after rain. Most enquiries from Horseport start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Horseport, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

How a job runs

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Horseport may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

What we need from you

  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints
  • Point out any areas we must not close

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Advice

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • The total length or number of joints
  • Access and working height
  • Induction, permit and paperwork requirements
  • The size and state of each joint

A quote for mastic joints depends on quantities, condition and access. Ask us for a fixed quote.

What we need to price the job

To price the job accurately, we need to understand the site. Send us:

  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • The type of building and who uses it
  • Access details, including height

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or send photos by email.

Why deal with it now?

Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish and one 12-month guarantee. Halls, stores and units around places like Horseport may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Mastic sealing in Horseport: the local picture

The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.

If you’re responsible for a building such as St Mary's Church, frame and door mastic needs the same attention as any other property. Landlords with units on estates such as Arch Farm Industrial Estate, 0.8 miles to the north-west of Horseport, can bring frame, door and external mastic across several units into one programme. Site managers at schools like Fordingbridge Infant School can fit frame mastic into the summer works.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Protect low-level joints in entrances
  • Mention RAMS, insurance or CSCS requirements up front
  • Have the asbestos survey to hand for older buildings
  • Avoid piecemeal callouts where you can

Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.

Horseport: questions and answers

Does your area include sites such as Arch Farm Industrial Estate, near Horseport?

Yes. We cover Horseport and the area around it, including industrial estates, business parks and retail parks such as Arch Farm Industrial Estate. Photos and a short description are enough for a first look.

Is a smaller place like Horseport outside your area?

No. Places such as Horseport are covered as much as the big towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you do block-wide mastic programmes?

We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Can you seal joints high up on a block?

It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.

What’s the quickest route to a quote?

There are 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.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
