How we handle facade sealing in Stubbings

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around. If you’re dealing with patch repairs that keep failing and perimeter joints where frames meet the structure, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Stubbings is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Stubbings, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we will quote to suit.

Facades, frames and programmes in Stubbings

Stubbings lies roughly 29 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

When a school such as Burchetts Green CofE Infants' School is extended or refurbished, the mastic package is often squeezed into the holidays. When units on a site such as Rashleighs Business Centre, 0.5 miles north-east of Stubbings, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Stubbings is about 2 miles west of Maidenhead, in Windsor and Maidenhead. We cover commercial sites throughout Stubbings, whether it’s a single job or part of a planned programme. Stubbings is one of 60 places in Windsor and Maidenhead on our list for facade joints. Reading is covered too, some 10 miles away.

On site: what to expect

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Stubbings need work, visits can be combined. A fixed quote is given before anything 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 is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Let us know about inductions and permits
  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000

Advice

Why act early in Stubbings

Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. For buildings around smaller places like Stubbings, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

FAQs: Stubbings

Is hospital work, at somewhere like St Mark's Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you plan work around the academic year at somewhere like Berkshire College of Agriculture?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you just add new sealant on top?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.

How much does the work cost?

There isn’t a price list, as every site differs. Send photos or drawings and we will price it at a fixed figure.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Is old mastic on our building likely to contain asbestos?

It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.

What the job involves on each surface

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint rather than the system it surrounds.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end to the correct depth.

What we’re called out for in Stubbings

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.

Typical triggers for a call:

  • Failed seals around shopfront and entrance frames
  • Air leaks through failed facade joints
  • Weathered facade joints that have lost their grip
  • Unsightly perimeter sealant on a visible elevation

For contractors at a college like Berkshire College of Agriculture, which lies west of Stubbings, perimeters and internal sealant are timed for the holidays.

Before you book anyone

  • Who will actually carry out the work
  • Is the sealant right for the movement and the substrate?
  • Can the work be phased to keep areas open?
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
