Facade sealing for Perry Green sites

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

How the quote is worked out

We price every job individually. The main factors are:

  • Access and working height
  • Which sealant the job calls for
  • Removal of failed or old sealant
  • Quantities, in metres or numbers

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Drawings or a marked-up plan, if available
  • The asbestos register, for older buildings
  • Clear photos of the problem areas
  • Your programme or deadline

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, phone 01277 525 020 or send photos by email.

Facade sealing in Perry Green, done properly

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip. If the evidence points away from the sealant, we say so before quoting. Most enquiries involve hard, chalky sealant that no longer flexes and discoloured or dirty facade joints, across shopfront frames, stone and brick facade joints and window and door perimeters. Facilities teams, main contractors and managing agents in Perry Green tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In the countryside around places like Perry Green, 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.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. If others near Perry Green need work, visits can be combined. A fixed quote is given before anything starts.

  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. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Agree which areas must stay open
  • Share the asbestos register for older buildings
  • Move anything stored against the joints

Keeping the joints sound

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Inspect facade joints on a regular cycle
  • Never let anyone seal over old sealant
  • Combine resealing with other works that need access
  • Record the product and colour used on each elevation

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.

Building and refurbishing in Perry Green

At about 40 miles from central London, Perry Green is within reach of the capital. 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. Perry Green 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, so we time external mastic for dry faces and agree it with the site team.

Units on estates such as Lanham Business Park, 1 mile west of Perry Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Projects at schools like Alec Hunter Academy work to term dates, so mastic is programmed tightly. For a contractor working at a hospital such as William Julien Courtauld Hospital, which lies west of Perry Green, perimeter and facade sealing is planned around patients and deliveries.

Perry Green is about 3 miles south-east of Braintree, in Essex. We cover Perry Green, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Perry Green is one of 644 places we cover in Essex for facade joints. We also cover London, around 40 miles from Perry Green.

What we can’t put right

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

  • Specialist high-level access methods
  • Movement beyond what any sealant can handle
  • Installing or repairing glazing systems

Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.

Joints and surfaces we work on

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

Why deal with it now?

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. Older rural buildings around Perry Green 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.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

How the job changes by surface

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.

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.

Your questions answered

Would you work within a site like William Julien Courtauld 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.

Do you cover business parks and estates near Perry Green, such as Lanham Business Park?

Yes. We cover Perry Green and the area around it, including industrial estates, business parks and retail parks such as Lanham Business Park. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we’ll set out a timescale with the quote.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you hold CHAS accreditation?

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

What type of sealant goes on window perimeters?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
