Coloured sealant across Dial Post

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Coloured sealant in Dial Post

A colour-matched bead still has to work as a seal. Faces are prepared, depth is fixed with rod and the bead is tooled onto two sides only, exactly as for a standard colour. Careful masking keeps the edges crisp. We work on natural stone and brick, shop-fit joinery and counters and powder-coated and anodised frames, and the failures we’re asked to look at most are smeared sealant on stone or joinery and standard-colour sealant spoiling a high-end finish. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Dial Post, that means joint design, primers and backing rod as standard.

Work in smaller places such as Dial Post tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What affects the price in Dial Post

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Whether old sealant has to be cut out first
  • Phasing around occupants
  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Details that help us quote

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

  • Clear photos of the problem areas
  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • The postcode of the building

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Different surfaces, different methods

Office fit-outs

Office joinery and frames usually follow a colour scheme. We choose sealant colours to suit.

Shop-fit and joinery finishes

Counters, display units and wall linings are seen close up. A sharp, even bead is as important as the colour.

Commercial premises in Dial Post

Central London is about 39 miles from Dial Post. This part of the South East is dense with business parks and out-of-town offices. Occupiers with several premises in the region tend to prefer one contractor and one point of contact. Less than 3 miles from Dial Post there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it.

If you run an office at a site such as Pondtail Farm (Business Park), 2.2 miles to the north of Dial Post, the sealant at reception desks, tea points and frames ages with each fit-out.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Questions about Dial Post

Do you cover business parks and estates near Dial Post, such as Pondtail Farm (Business Park)?

Yes. Our area takes in Dial Post and its surroundings, with estates and business parks such as Pondtail Farm (Business Park) included. To start, just phone 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Is a smaller place like Dial Post outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you do a sample bead?

Yes. We can fit a sample into the programme.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Dial Post can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we agree which sealant type the joint needs.
  2. We compare the target colour with the colours available.
  3. You approve the colour, on site if it’s critical.
  4. We cut out the existing bead, clean and set the depth.
  5. Edges are masked and the coloured sealant applied and tooled.
  6. We remove the masking and walk the finished joints with you.

Preparing the site

  • Have the specification and drawings to hand
  • Make sure the joints can be reached
  • Tell us your opening times and when work is allowed

Ask for a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, phone 01277 525 020 or send details through our quote form.

Advice

When to call us in Dial Post

A coloured joint can fail like any other: splits, adhesion loss and hardening all happen. We cut out and reseal in the agreed colour.

Any of the following is a good reason to get the joints checked over:

  • Old colour-matched joints lifting at the edges
  • Shop fits that need consistent sealant colours across sites
  • Weathered sealant that no longer matches
  • Marked sealant in hotel bathrooms

Sites a few miles apart, such as Pondtail Farm (Business Park) and Huffwood Trading Estate, can share one programme and one point of contact.

What to look for in a quote

  • Their approach to joint depth and backing
  • Their public liability cover
  • Who will actually carry out the work
  • Will failed sealant be removed rather than covered?

Questions to ask before you appoint anyone

Leave it or put it right?

A failed joint lets in water and dirt, whatever colour it is. Behind the bead, moisture can damage substrates and finishes. Halls, stores and units around places like Dial Post 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.

Pricing colour-matched joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
