Mastic sealing in Margate

Across Margate and the rest of Kent, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on external wall and movement joints, communal kitchens and washrooms and window and door perimeters on blocks, and the usual reasons a site gets in touch are window mastic that has split and shrunk and estate-wide sealant that is simply worn out. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Margate it comes down to the same thing: the right product in a properly prepared joint.

Older buildings in towns like Margate have often had replacement windows fitted at different times, so mastic around them can be of mixed age and quality. A look at the whole building shows which joints need doing now.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Frames, entrances and external joints in Margate

With the shore within about 1 mile, Margate counts as a coastal location. On buildings near the shore, the side facing the weather usually needs its mastic renewed first. Margate is about 64 miles from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.

Trustees of buildings like Parish Church of St John the Baptist can bring frame and external mastic into a planned maintenance list. If your remit includes a building such as Salmestone Primary School, frame and door mastic can be programmed for the holidays. For agents with blocks near Margate station, which lies north-west of Margate, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Maintenance after handover

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Have the asbestos survey to hand for older buildings
  • List the paperwork your organisation requires when you send details
  • Track which buildings were done and when
  • Prioritise elevations facing the weather

Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.

One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.

Quoting for work in Margate

These are the things that shape the price:

  • Specialist products, such as fire-rated or hygienic sealants
  • The total length or number of joints
  • Whether old sealant has to be cut out first
  • Induction, permit and paperwork requirements

A quote for mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • A wide shot and a close-up of the area
  • Access details, including height
  • The type of building and who uses it
  • The postcode of the building

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to phone 01277 525 020 or send photos by email.

Leave it or put it right?

A bead run over old mastic can look like a repair. It doesn’t bond and typically fails within a short time. Cutting out and resealing properly does it once. A failed joint is easier to put right before damp shows inside. After a leak, there’s drying, repairs and redecoration on top.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why us?

  • Failed material removed, not covered up
  • CHAS accredited
  • Colours confirmed for the specified product
  • One phone line for London, the South East and Scotland

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a town like Margate, we try to group jobs for the same client into one visit. Give us your access times and we will fit the work in.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the 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.

Preparing the site

  • Confirm the product named in the specification
  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits

Request a quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Questions about Margate

Can you work at a site such as All Saints Industrial Estate, by Margate?

Yes. Estates, retail parks and business parks around Margate, All Saints Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Our building in Margate 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 work in Margate?

Yes. We cover Margate, and the simplest way to start is to speak to us on 01277 525 020 or use the quote form.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.

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 entrances stay in use.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Do you do block-wide mastic programmes?

Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Should maintenance staff do it?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
