Facade sealing near Dunsfold

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

What happens if it’s left?

Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Halls, stores and units around places like Dunsfold may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Why appoint us

  • A fixed quote before work starts
  • Our applicators hold CSCS cards

About our facade sealing in Dunsfold

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters. We work on shopfront frames, perimeter joints where frames meet the structure and stone and brick facade joints, and the failures we are asked to look at most are gaps between rainscreen or cladding panels and patch repairs that keep failing. Most enquiries from Dunsfold 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.

Sites around smaller places like Dunsfold can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we will quote to suit.

Work we carry out in Surrey comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or send details through our quote form and we’ll come back to it.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Report water ingress at frames as soon as it shows
  • Check that rainwater leaves the facade the way it was designed to
  • Note when each elevation was last resealed
  • Inspect facade joints on a regular cycle

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal across the elevation.

Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

FAQs: Dunsfold

Would you work within a site like Milford Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Dunsfold too small for you to travel to?

No. Places such as Dunsfold are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Do we need an asbestos check before resealing?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, and we will ask to see it. Suspect material is left alone until it has been tested.

Who decides which product is used?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

How do we ask for a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email the details over. Include photographs or drawings if you have them.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Dunsfold, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Make sure the joints can be reached
  • Tell staff and tenants when we’ll be in
  • Send any specification or drawings in advance

What affects the price in Dunsfold

To price the job, we consider:

  • How much existing material needs removing
  • Travel to remote or island sites
  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation

There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.

What to include in your enquiry

However big the job, the same details help:

  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available
  • When you need the work done
  • How the joints are reached, and at what height

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email a schedule or drawings.

Different surfaces, different methods

Brick and stone facades

Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use, with masked edges for a clean line.

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.

Owners, agents and contractors

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Dunsfold can sit alongside others in a wider programme across Surrey.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Sites and facades in and around Dunsfold

Dunsfold lies roughly 33 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. Dunsfold 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 we time external mastic for dry faces and agree it with the site team.

New units and refits on sites such as Littlemead Industrial Estate, 3 miles north-east of Dunsfold, need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as Milford Hospital, 4.3 miles north-west of Dunsfold, perimeter and facade sealing is planned around patients and deliveries.
