Facade sealing in Sherington

Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. If you have weathered facade joints that have lost their grip and damp patches beside frames after rain, we can help. A single leaking joint is often how a building in Sherington first comes to us: we look at the rest while we are there and tell you what we find.

Construction in and around smaller places such as Sherington is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Different surfaces, different methods

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and areas needing repair are flagged.

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone.

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Share access with other external trades
  • Keep pressure washers away from fresh sealant
  • Keep the sealant details on the building file
  • Investigate damp beside windows promptly

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade.

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

When something else is needed

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

  • Joints too narrow for the movement they take, which need redesign
  • Water getting in through cracked render or porous masonry
  • Providing access systems for the work

Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

What we seal

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

For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Facades, frames and programmes in Sherington

A 2-mile radius around Sherington takes in a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. At about 50 miles from central London, Sherington is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

Older buildings in the area around Sherington, such as Linford Manor, 3.6 miles to the south-west of Sherington, need care when sealed: the product has to suit soft or historic materials. Projects at schools like Sherington Church of England School work to term dates, so mastic is programmed tightly. University estates such as Cranfield University (to the south-east of Sherington) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Sherington is about 2 miles north-east of Newport Pagnell, in Milton Keynes. We cover commercial sites throughout Sherington, for single jobs and planned programmes alike.

Common questions from Sherington clients

Is Sherington off your patch?

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

Will you take on work at estates like Cromwell Business Park, close to Sherington?

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

Can the building stay open while you work?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

How is access to upper-level joints handled?

That comes down to the access arranged for the job. Share what access exists or is planned when you send details.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Should we check old sealant for asbestos?

In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. We don’t remove asbestos-containing materials.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Sherington are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First we review photos, 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. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work
  • Let us know about inductions and permits

Cost factors for facade joints

To price the job, we consider:

  • The site’s rules and procedures
  • Access and working height
  • Quantities, in metres or numbers
  • Which sealant the job calls for

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Details that help us quote

To price the job accurately, we need a clear picture of the site. Send us:

  • Asbestos survey details if the building is older
  • The product your specification calls for
  • A wide shot and a close-up of the area
  • Any dates the work must fit around
