Facade sealing for Four Throws sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Damp caused by condensation inside the building
  • Render or concrete edges that have broken away
  • Joints too narrow for the movement they take, which need redesign

If you’re not sure, just phone 01277 525 020 or email us and we will give you a straight answer before you book.

Surfaces we seal

  • Coping and flashing joints
  • Window and door perimeters
  • Stone and brick facade joints
  • Cladding panel joints
  • Shopfront frames
  • Perimeter joints where frames meet the structure

How we handle facade sealing in Four Throws

External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. The enquiries we see most involve draughts around frames and panels and staining on stone next to old sealant, across window and door perimeters, coping and flashing joints and perimeter joints where frames meet the structure. A specialist sealant contractor works differently from a general builder: in Four Throws, that means joint design, primers and backing rod as standard.

In the countryside around places like Four Throws, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Mastic packages on Four Throws sites

Central London is about 42 miles from Four Throws. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.

When a school such as Hawkhurst Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. New units and refits on sites such as Hawkhurst Station Business Park (2 miles north-west of Four Throws) need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as Hawkhurst Community Hospital, 2.1 miles west of Four Throws, perimeter and facade sealing is planned around patients and deliveries.

Four Throws is about 12 miles north of Hastings, in Kent. Four Throws sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Four Throws is one of 931 places in Kent on our list for facade joints. We also cover Brighton, around 32 miles from Four Throws.

Business premises anywhere in TN18 are within our area for facade joints. For a building on Rye Road, Foxhole Lane and Conghurst Lane or nearby, send details and we will quote for facade joints. Just outside Four Throws, we also work in Little Conghurst (1 mile south-west), Pipsden (1 mile north-west), Hawkhurst (1 mile north-west), The Moor (1 mile west) and Sandhurst Cross (1 mile south-east). Nearby towns on our patch include Royal Tunbridge Wells (13 miles north-west), Paddock Wood (11 miles north-west), Tenterden (7 miles east), Southborough (14 miles north-west), Park Wood (14 miles north) and Staplehurst (9 miles north).

Doing it in-house

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Smaller jobs around Four Throws can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we will be in
  • Confirm the product named in the specification

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Advice

What happens if it’s left?

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure, often turning up far from the joint. For buildings around smaller places like Four Throws, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Why appoint us

  • RAL and finish matching where the product range allows
  • Coloured sealants to suit the setting, where available
  • Products installed to the manufacturer’s instructions
  • Public liability insurance in place

Quoting for work in Four Throws

These are the things that shape the price:

  • Phasing around occupants
  • How accessible the joints are
  • Induction, permit and paperwork requirements
  • Travel to remote or island sites

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Sending details for a quote

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

  • What the building is and how it’s used
  • The asbestos register, for older buildings
  • Rough lengths or quantities, or drawings if you have them
  • The site address and postcode

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

FAQs: Four Throws

Do you take on work at healthcare sites like Hawkhurst Community Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How many days will you need on site?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

Do you replace windows or glass?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

Are you CHAS accredited?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

How is access to upper-level joints handled?

That varies with the building and the access on offer. When you call the office on 01277 525 020 or email the details over, describe the access, and we’ll agree the approach together.

How the job changes by surface

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod.

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each surface.
