How we handle facade sealing in Daws Heath

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. Most enquiries involve staining on stone next to old sealant and cladding panel joints that have opened up, on cladding panel joints, perimeter joints where frames meet the structure and shopfront frames. Searching for sealant specialists in Daws Heath? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Around smaller places like Daws Heath, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Daws Heath: questions and answers

Will you take on work at estates like Brook Road Industrial Estate, close to Daws Heath?

Yes. We cover Daws Heath and the area around it, including industrial estates, business parks and retail parks such as Brook Road Industrial Estate. A few photographs and the unit address let us price the work.

Could you schedule work at a campus like University of Essex for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you work on upper floors?

Access is planned with you before we quote. Let us know what access is in place or planned, and we will price the work around it.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Can you work while the building is occupied?

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

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Damaged frames that need replacing
  • Specialist high-level access methods
  • Movement beyond what any sealant can handle

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.

Surfaces we seal

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

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Access and working height
  • Whether old sealant has to be cut out first
  • Travel to remote or island sites
  • Whether the work must be split into stages

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Before you send an enquiry

However big the job, these details speed things up:

  • Whether the building will be occupied during the work
  • The postcode of the building
  • Rough lengths or quantities, or drawings if you have them
  • How the joints are reached, and at what height

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email drawings and photos.

Common problems we fix in Daws Heath

Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

Most enquiries start with one or more of the following:

  • Cladding panel joints that have opened up
  • Hard, chalky sealant that no longer flexes
  • Discoloured or dirty facade joints
  • Perimeter joints where frames meet the structure

Hotel extensions and refits, at places such as Barnabys Hotel, 1.2 miles to the north of Daws Heath, normally run between busy periods, so the sealing is squeezed into short windows.

What to look for in a quote

  • Proof of insurance
  • How they handle RAMS and site documents
  • The terms of the workmanship guarantee
  • Do they follow the manufacturer’s priming guidance?

How to choose a sealant contractor

From enquiry to sign-off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. Jobs in and around smaller places like Daws Heath are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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. Failed beads are removed in full and the joint faces cleaned.
  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

  • Have the specification and drawings to hand
  • For older buildings, check the asbestos register before work
  • Make sure the joints can be reached

Facade sealing in Daws Heath: the local picture

The sea is no more than about 3 miles from Daws Heath. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. The South East is one of the drier parts of the UK. 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.

When a college such as South Essex College Stephenson Road Campus, 1.4 miles east of Daws Heath, builds or refurbishes, the mastic package typically has to fit around students and staff. Building work at universities like University of Essex, 4.7 miles to the south-east of Daws Heath, is often timed for the summer, mastic included.

What the job involves on each 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, primed where the maker specifies.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.
