Construction mastic in Yelsted

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Specifying the product where the designer hasn’t
  • Approving fire stopping as compliant
  • Faulty frames rather than failed sealant

If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think before you book.

Where we work in Yelsted

  • Window and door perimeters
  • Brick and block movement joints
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Floor and skirting junctions
  • Sanitary and kitchen joints

Construction mastic in Yelsted

The specification and the programme set the job. Where the specification names a product, we use it. Backing, primer and depth follow what the sealant maker sets out, so the joints perform as the designer intended. Site teams most often ask us about failed sealant in an existing building being refurbished and frame perimeters left unsealed or poorly sealed, across internal decorators’ caulk, sanitary and kitchen joints and floor and skirting junctions. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Yelsted is the same: the right product in a properly prepared joint.

For a site near Yelsted, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Your questions answered

Can you work at a site such as Parkwood Shopping Centre, by Yelsted?

Yes. Estates, retail parks and business parks around Yelsted, Parkwood Shopping Centre among them, are all within reach. Photos and a short description are enough for a first look.

Is hospital work, at somewhere like KIMS hospital, something you do?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Do you do fire-rated sealing on new builds?

Where it’s specified, yes. If the detail calls for collars, wraps or batts instead, we’ll tell you.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Contractors’ notes for Yelsted

Yelsted is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. At about 33 miles from central London, Yelsted is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

Hospital estates such as KIMS hospital, 4 miles to the south-west of Yelsted, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. School extensions, at buildings such as St Augustine of Canterbury Catholic Primary School, typically run to the summer holidays, mastic included. For contractors refurbishing units at places like Parkwood Shopping Centre, which lies north-west of Yelsted, the mastic covers cladding panels, roller-door and window perimeters.

Yelsted is about 3 miles south-east of Gillingham, in Kent. Any commercial site in Yelsted is covered, whether it’s a single job or part of a planned programme. Yelsted is one of 931 places we cover in Kent. Our London page has more on work in that area.

Why deal with it now?

Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal and that’s a far smaller job. We’ll say so if a frame itself is the problem. For buildings around smaller places like Yelsted, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

What sets the cost

What shapes the price:

  • How much existing material needs removing
  • Phasing around occupants
  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

What we need to price the job

The more we know, the firmer the quote. Helpful details to send:

  • The type of building and who uses it
  • Access details, including height
  • Any specification or named product
  • A wide shot and a close-up of the area

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Yelsted. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Yelsted, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. First we look at the scope on site or from drawings.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Paperwork is agreed and applicators are inducted on site.
  4. Sealing follows the programme as areas are released.
  5. Problems we find, such as oversized gaps, are raised straight away.
  6. Final snagging is completed and the 12-month guarantee applies.

Advice

How the job changes by surface

External facade and movement joints

External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it.

Kitchens and utility areas

On commercial kitchen fit-outs, hygienic sealants are often specified. We follow the specification and seal to a smooth, cleanable finish.
