FAQs: Capel Cross

Is a smaller place like Capel Cross outside your area?

No. Places such as Capel Cross are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

What paperwork can you provide for a job in Capel Cross?

RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

About our construction mastic in Capel Cross

Site managers want applicators who turn up with the right cards and paperwork. We’re a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. Most enquiries involve inconsistent sealant finishes from plot to plot and mastic snags holding up handover, on window and door perimeters, internal decorators’ caulk and brick and block movement joints. One point of contact handles commercial sealant work in Capel Cross from the first photographs to the final walk-round, whether it’s one building or several.

Around smaller places like Capel Cross, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

How the quote is worked out

What shapes the price:

  • Whether old sealant has to be cut out first
  • How much there is to seal
  • Site requirements such as inductions and permits
  • Specialist products, such as fire-rated or hygienic sealants

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • A wide shot and a close-up of the area
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them
  • Access details, including height

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Different surfaces, different methods

Snagging before handover

The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area, cutting out damaged joints and resealing them properly.

External facade and movement joints

Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.

When something else is needed

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Defective windows, doors or glazing units (the supplier or installer’s job)
  • Designing joint widths or choosing the specification (that sits with the designer)
  • Oversized gaps that need packing or adjustment by others

Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly.

Surfaces we seal

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

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For a building around Capel Cross, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. Drawings, specification and programme come to us.
  2. Quantities are measured and a fixed price returned.
  3. We agree with the site team which areas come first.
  4. Plots or floors are sealed as they’re handed over.
  5. Joints are prepared, backed and sealed to the specification.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Preparing the site

  • Send your site hours and access windows
  • Agree which areas must stay open
  • Explain the parking and delivery arrangements

Quotes

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Advice

When to call us in Capel Cross

Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. We flag them early rather than filling them with sealant that won’t last.

Site and facilities staff are often the first to spot these:

  • Caulk cracking where joints are moving more than expected
  • A long mastic snag list close to completion
  • Inconsistent sealant finishes from plot to plot
  • Early adhesion failures on new external joints

Older buildings in the area around Capel Cross, such as Scotney Castle (3.4 miles south-west of Capel Cross), need care when sealed: the product has to suit soft or historic materials.

What your quote should include

  • The terms of the workmanship guarantee
  • Will failed sealant be removed rather than covered?
  • The named product and why it was chosen
  • Their plan for phasing and protecting the area

Choosing a commercial sealant contractor

Why act early in Capel Cross

On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal, which is a much smaller cost. If the frame is life-expired, we’ll tell you. Older rural buildings around Capel Cross move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Why appoint us

  • Products installed to the manufacturer’s instructions
  • Over 20 years of commercial sealing
  • CSCS-carded applicators
  • One number for every site we cover

Construction mastic in Capel Cross: the local picture

At about 34 miles from central London, Capel Cross is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. Capel Cross sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager.

Projects at schools like Horsmonden Primary School work to term dates, so mastic is programmed tightly.
