Construction mastic across Balls Cross

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle construction mastic in Balls Cross

Getting a subcontractor through site induction should be simple. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. Most enquiries involve external joints sealed in damp or cold conditions that are now failing and snag items on joints that need redoing before handover, across brick and block movement joints, window and door perimeters and sanitary and kitchen joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Balls Cross, preparation and product choice get the time they need.

Conversions of older rural buildings near smaller places such as Balls Cross bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What sets the cost

We price every job individually. The main factors are:

  • Working within restricted access windows
  • Specialist products, such as fire-rated or hygienic sealants
  • How much there is to seal
  • How much existing material needs removing

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Asbestos survey details if the building is older
  • Access details, including height
  • Specification clauses that apply
  • Clear photos of the problem areas

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email a schedule or drawings.

Why deal with it now?

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility and a consistent finish. Converted and older buildings near places like Balls Cross tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What you get with us

  • Colours chosen to suit frames, cladding or finishes where possible
  • Constructionline member
  • Public liability insurance in place
  • A fixed quote before work starts

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Surface by surface

Fire-rated sealant where specified

Not every penetration suits a sealant. Other products are used for some services and gaps. Record requirements are agreed with the quote.

External facade and movement joints

Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it and work only when conditions suit.

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

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, with each stage agreed with your site contact.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If others near Balls Cross need work, visits can be combined. You will have a fixed quote before work starts.

  1. We start with the drawings, specification and programme.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  4. Plots or floors are sealed as they’re handed over.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Preparing the site

  • Have the specification and drawings to hand
  • Send your site hours and access windows
  • Clear stock, furniture or equipment away from the joints

Getting a fixed quote

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send photos by email.

Facades, frames and programmes in Balls Cross

At about 39 miles from central London, Balls Cross is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Rainfall across the South East, Balls Cross included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

Older buildings in the area around Balls Cross, such as Petworth House, 2.9 miles to the south of Balls Cross, need care when sealed: the product has to suit soft or historic materials. Recladding or extending a unit at a site like Colhook Industrial Park., 1.4 miles west of Balls Cross, brings panel joints and frame perimeters into the programme.

Your questions answered

Is Balls Cross too small for you to travel to?

Not at all. Balls Cross is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work to our programme on a site in or near Balls Cross?

Yes. The mastic is planned around your key stages. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Do you guarantee new-build sealant work?

Each package is backed by a 12-month guarantee. We are also fully insured for public liability.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Can you clear a mastic snag list before handover?

Yes. We can work through a mastic snag list area by area before handover, cutting out damaged or poor joints and resealing them.
