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

Owners, agents and contractors

Building owners and managing agents use us on everything from one building to a spread of sites around Halfway Houses. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Construction mastic for commercial buildings in Halfway Houses

Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work, so we plan elevations with the forecast and the programme in mind. Internal sealing often fills those days. We work on sanitary and kitchen joints, brick and block movement joints and window and door perimeters, and the usual reasons a site gets in touch are different trades sealing to different standards and mastic snags holding up handover. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Halfway Houses, preparation and product choice get the time they need.

Around places like Halfway Houses, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Diagnose, treat, sign off

At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. If neighbouring businesses or buildings around Halfway Houses need work too, visits can be combined. Tell us your site hours and we’ll plan around them.

  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. The package is closed out, snags cleared and backed by our 12-month guarantee.

What we need from you

  • Flag any permit to work we will need
  • Have the specification and drawings to hand
  • Tell staff and tenants when we will be in

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Maintenance after handover

Once the work is signed off, these steps help:

  • Don’t force external sealing on a damp or frosty day
  • Brief following trades on areas that have been sealed
  • Put any product change through the designer first
  • Note which sealant went where at handover

The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.

A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating, and a delay to handover. A check of every frame before decorators start is worth the time.

Should maintenance staff do it?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Leave it or put it right?

Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. Damaged joints are removed and resealed from clean faces. For buildings in places like Halfway Houses, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

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 you’ll have a fixed figure to work with.

Why us?

  • Fully insured, including public liability cover
  • One number for every site we cover
  • Our applicators hold CSCS cards
  • A Constructionline member, so easy to vet

Halfway Houses: questions and answers

Is Halfway Houses too far out for you?

Not at all. Halfway Houses is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Our building in Halfway Houses 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. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Can you seal external joints in wet or cold weather?

External sealing goes ahead only with a dry joint inside the product’s temperature range. Wet or cold joints cause adhesion problems so it’s better to wait.

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes a day or two on a small fit-out and several weeks on a large multi-storey package. Larger or phased jobs take longer, and we will give you a timescale with the quote.

What site paperwork can you supply?

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

Is any job too small?

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

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Glazing units that are cracked or misted
  • Specifying the product where the designer hasn’t
  • Damage to finishes by other trades after we have sealed

If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

What we seal

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

Sites and facades in and around Halfway Houses

Halfway Houses lies within about 2 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Rainfall across the South East, Halfway Houses included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.

Hospital estates such as Sheppey Community Hospital (0.9 miles east of Halfway Houses) 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. For contractors at a school such as Halfway Houses Primary School, sealing has to be finished before term starts. When units on a site such as Walbrook Business Park, 0.8 miles to the south-west of Halfway Houses, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Halfway Houses is about 1 mile west of Minster, in Kent. We send applicators to Halfway Houses for mastic packages, handled exactly as we handle every other area. Across Kent, 931 places are covered, Halfway Houses among them. For work in that direction, see our London page (38 miles or so).
