Need facade sealing in Dragons Green?

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

Building owners, agents and FMs in Dragons Green

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Facade sealing in Dragons Green

Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. If you have hard, chalky sealant that no longer flexes and staining on stone next to old sealant, we can help, on perimeter joints where frames meet the structure, window and door perimeters and stone and brick facade joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Dragons Green, preparation and product choice get the time they need.

Conversions of older rural buildings near smaller places such as Dragons Green 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 typically what’s needed.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or email the details over and we will arrange a return visit.

Dragons Green: questions and answers

Is Pondtail Farm (Business Park), near Dragons Green, within your area?

Yes. Estates, retail parks and business parks around Dragons Green, Pondtail Farm (Business Park) among them, are all within reach. A few photographs and the unit address let us price the work.

Is Dragons Green too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How do you choose the sealant?

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.

When can you be on site?

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

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Is it okay to overlay old mastic?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.

How much does the work cost?

We don’t publish prices, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For work around Dragons Green, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Let building users know which areas are affected
  • Tell us what induction or permit system the site runs
  • Point out parking and an unloading spot

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send photos by email.

Building and refurbishing in Dragons Green

Dragons Green is in the South East, one of the UK’s drier regions. 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. Dragons Green is about 37 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

Hospital estates such as Horsham Hospital, 5.4 miles north-east of Dragons Green, 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 Shipley CofE Primary School, typically run to the summer holidays, mastic included. Recladding or extending a unit at a site like Pondtail Farm (Business Park) (1.3 miles east of Dragons Green) brings panel joints and frame perimeters into the programme.

Dragons Green is about 5 miles south-west of Horsham, in West Sussex. We cover Dragons Green, with the same fixed quotes and 12-month guarantee as everywhere else. Across West Sussex, 373 places are covered, including Dragons Green. Sites around Brighton have their own page, roughly 16 miles from Dragons Green.

Business premises anywhere in RH13 are within our area. If your site is on Dragons Lane and Dragons Green Road or close by, we can quote for facade joints. If your building is just outside Dragons Green, we cover Shipley (1 mile south), Whitehall (1 mile south), Broomer's Corner (2 miles south-west), Dial Post (3 miles south) and West Grinstead (3 miles south-east). Bigger towns within reach include Crawley (11 miles north-east), Horsham (5 miles north-east), Worthing (12 miles south), Haywards Heath (12 miles east), Burgess Hill (11 miles east) and Littlehampton (15 miles south-west).

Why deal with it now?

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Older rural buildings around Dragons Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Why us?

  • Old sealant cut out, never sealed over
  • 12-month guarantee on workmanship
  • Specification-led, product-correct work
  • A fixed quote before work starts

Different surfaces, different methods

Cladding panel joints

Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.

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.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • The total length or number of joints
  • How much existing material needs removing
  • Whether the work must be split into stages
  • Which sealant the job calls for

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.

What to include in your enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • The type of building and who uses it
  • Any dates the work must fit around
  • Approximate linear metres or a joint schedule
  • Access details, including height

For a fixed quote, ring 01277 525 020 or email the details over with the site address and an outline of the work. You can also send details through our quote form.

When something else is needed

We check first that sealant really is the fix. It isn’t the answer for:

  • Water getting in through cracked render or porous masonry
  • Providing access systems for the work
  • Joints whose design needs changing by the specifier

If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
