Mastic sealing for Highstead sites

Mastic sealing in Highstead, done properly

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded and we hold public liability insurance. Resealed mastic joints in Highstead carry our 12-month guarantee. The enquiries we see most involve complaints coming in block by block and worn sealant at communal door frames, on external wall and movement joints, balcony and threshold joints and shopfronts below residential blocks. Whether you call it commercial sealant work, mastic application or joint sealing, in Highstead it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In and around smaller places like Highstead, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

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

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Broken glass or failed sealed units
  • Asbestos-containing sealant, which we don’t remove

If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think before you book.

Building owners, agents and FMs in Highstead

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Highstead need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Looking after the joints

Regular inspection catches problems early. In particular:

  • Start inspections with the most exposed faces
  • Log resealing dates block by block
  • Encourage occupiers to report problems at frames
  • Keep bins and bikes away from communal door frames

Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.

Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.

Trustees of buildings like Church of St Mary the Virgin can bring frame and external mastic into a planned maintenance list.

Leave it or put it right?

A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Around Highstead, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

FAQs: Highstead

Is Highstead too far out for you?

No. Places such as Highstead are covered as much as the big towns. We cover Greater London and the counties of 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 cover business parks and estates near Highstead, such as Chislet Business Park?

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

Can you take on resealing for a block portfolio?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Will residents or tenants be disturbed?

The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
