Facade sealing for commercial buildings in Rayleigh

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. If you are dealing with draughts around frames and panels and hard, chalky sealant that no longer flexes, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Rayleigh it comes down to the same thing: the right product in a properly prepared joint.

Many towns of Rayleigh’s size have older buildings being converted or extended, so new windows and cladding meet old masonry. Those junctions need a sealant and primer that suit both surfaces.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

How the job changes by surface

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone, and primers go on where specified.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints.

After the work

For the best life from the joints:

  • Brief window cleaners about newly sealed joints
  • Confirm the survey covers external sealants in older buildings
  • Never let anyone seal over old sealant
  • Plan facade sealing alongside redecoration

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.

What affects the price in Rayleigh

These are the things that shape the price:

  • How much existing material needs removing
  • Working within restricted access windows
  • The size and state of each joint
  • Quantities, in metres or numbers

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Before you send an enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Any dates the work must fit around
  • The product your specification calls for
  • Access details, including height
  • The postcode of the building

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or email drawings and photos with what you know.

Why deal with it now?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. In a town like Rayleigh, a split, stained or mouldy joint is often the first thing visitors notice. Renewing it keeps the building looking cared for.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why appoint us

  • Colours chosen to suit frames, cladding or finishes where possible
  • Work carried out by CSCS-carded applicators
  • Standard and matched colours in many product ranges
  • Failed material removed, not covered up

Rayleigh: questions and answers

Does your area include sites such as Imperial Park Industrial estate, near Rayleigh?

Yes. Our area takes in Rayleigh and its surroundings, with estates and business parks such as Imperial Park Industrial estate included. Photos and a short description are enough for a first look.

Do you take on work at healthcare sites like Chartwell Private Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you replace windows or glass?

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

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do you run new sealant over the existing bead?

No. New sealant won’t hold on old sealant, so the old bead is cut away and the faces are cleaned before resealing. Nothing else gives a bond that lasts.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we will send them with the quote.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. If you have more than one building in Rayleigh, they can often be done on the same visit. Give us your access times and we’ll fit the work in.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Send your site hours and access windows
  • Tell staff and tenants when we’ll be in
  • Flag any permit to work we will need

Related advice

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Mastic packages on Rayleigh sites

Rayleigh is about 31 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. A 2-mile radius around Rayleigh takes in a number of hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.

Extensions at sites like Chartwell Private Hospital, 3.2 miles to the south-east of Rayleigh, usually sit beside working departments, and the mastic follows strict access rules. When a college such as South Essex College Stephenson Road Campus, 2.3 miles to the south-east of Rayleigh, builds or refurbishes, the mastic package normally has to fit around students and staff. Projects at schools like Glebe Primary School work to term dates, so mastic is programmed tightly.

Rayleigh is about 5 miles north-west of Southend-on-Sea, in Essex. Businesses, contractors and managing agents in Rayleigh use us for work on facade joints. Across Essex, 644 places are covered, Rayleigh among them. London is covered too, around 31 miles from Rayleigh.

Access to Rayleigh is via the A127 and A129. Nearby places we also cover include Daws Heath (2 miles south), Hadleigh (3 miles south), Hawkwell (3 miles east), Eastwood (3 miles south-east) and Stroud Green (3 miles east) for facade joints.
