Facade sealing for Wyddial sites

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

Aftercare for building managers

Problems stay small when the joints are checked regularly. In particular:

  • Keep sills, gutters and drainage paths clear
  • Note when each elevation was last resealed
  • Plan facade sealing alongside redecoration
  • Don’t wait for a second leak before calling

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading behind the facade.

How we handle facade sealing in Wyddial

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, and we will fit the work around it. If you have failed seals around shopfront and entrance frames and unsightly perimeter sealant on a visible elevation, we can help. Most enquiries from Wyddial start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In the countryside around places like Wyddial, 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 usually what’s needed.

Our 12-month guarantee is about workmanship, not 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.

What the job involves on each surface

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, not the framing or glazing itself.

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod.

Questions about Wyddial

Is Wyddial too small for you to travel to?

Not at all. Wyddial is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Will you fit the mastic around our build programme in Wyddial?

Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Do we need an asbestos check before resealing?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can the building stay open while you work?

In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Can you work in cold or wet weather?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, so we plan around the forecast.

Facades, frames and programmes in Wyddial

Rainfall across the South East, Wyddial included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. Wyddial is about 32 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.

School extensions, at buildings such as Layston Church of England First School, usually run to the summer holidays, mastic included. Recladding or extending a unit at a site like Park Farm Industrial Estate, 1.3 miles south-west of Wyddial, brings panel joints and frame perimeters into the programme.

Wyddial is in Hertfordshire. Any commercial site in Wyddial is covered. Wyddial is one of 371 places in Hertfordshire on our list for facade joints. For work in that direction, see our London page (32 miles or so).

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

From enquiry to sign-off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. Rural sites near Wyddial may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  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. 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.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification

How the quote is worked out

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

  • Access and working height
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants
  • Removal of failed or old sealant

Pricing facade joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Sending details for a quote

Diagnosis starts before we arrive. Let us know:

  • Photos of the joints, close up and from further back
  • Where the site is, with the postcode
  • Whether the building will be occupied during the work
  • Anything awkward about access or site hours

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or send photos by email to discuss it first.

Leave it or put it right?

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer and avoids repeat call-outs. Halls, stores and units around places like Wyddial may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
