Facade sealing for Howe Green sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Facade sealing in Howe Green, done properly

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, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. If you are dealing with air leaks through failed facade joints and facade joints cracked through the middle, we can help, whatever the surface. Most enquiries from Howe Green start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Conversions of older rural buildings near smaller places such as Howe Green bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

How the job changes by surface

Brick and stone facades

Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair before sealing.

FAQs: Howe Green

Is Howe Green off your patch?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you work around term dates at a campus such as Anglia Ruskin University?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can the building stay open while you work?

Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Do you guarantee your work?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Which sealant do you use on facades?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.

Will rain stop the work?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, and we build that into the programme.

What we can’t put right

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Movement beyond what any sealant can handle
  • Water getting in through cracked render or porous masonry
  • Work on the window or framing system itself

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

What we seal

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

When to bring in a specialist

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Facade sealing in Howe Green: the local picture

Central London is about 30 miles from Howe Green. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. Howe 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 the external programme keeps a little slack.

When a college such as Chelmsford College Princes Road Campus (to the north-west of Howe Green) builds or refurbishes, the mastic package typically has to fit around students and staff. When units on a site such as Beehive Business Centre, 2.3 miles north-west of Howe Green, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Howe Green is about 3 miles south-east of Chelmsford, in Essex. Howe Green sits inside our coverage and the rest of Essex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

Signs you need facade sealing in Howe Green

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Look out for the following:

  • Hard, chalky sealant that no longer flexes
  • Failed sealant on precast panel joints
  • Facade joints cracked through the middle
  • Unsightly perimeter sealant on a visible elevation

Extensions at sites like Phoenix Hospital, 1.2 miles to the north-west of Howe Green, usually sit beside working departments, and the mastic follows strict access rules.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • What site paperwork they can supply
  • Is the sealant right for the movement and the substrate?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

Diagnose, treat, sign off

On arrival, 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 usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Smaller jobs around Howe Green can be grouped with others nearby. You will have a fixed quote before work starts.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed 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. We go over the completed work with you before leaving.

Preparing the site

  • Explain the parking and delivery arrangements
  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification
