How we handle facade sealing in Well End

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Most enquiries involve sealant pulling away from frames or panels and perimeter joints where frames meet the structure, across stone and brick facade joints, shopfront frames and cladding panel joints. Whoever orders the work in Well End, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Conversions of older rural buildings near smaller places such as Well End bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What we are called out for in Well End

Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.

Look out for the following:

  • Facade joints cracked through the middle
  • Air leaks through failed facade joints
  • Previous reseals run over old sealant
  • Leaks at window and door perimeters

Historic houses such as Cliveden (2.2 miles south-east of Well End) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • Whether old or failed sealant will be cut out, not overlaid
  • What level of public liability insurance do they hold?
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

Leave it or put it right?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Halls, stores and units around places like Well End may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Common questions from Well End clients

Is Well End too small for you to travel to?

No. Places such as Well End are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Do you take on work at healthcare sites like Marlow Community 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.

Can you work in cold or wet weather?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

How long does a typical visit take?

It depends on the scope, though a typical visit typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Do you run new sealant over the existing bead?

No. New sealant won’t hold on old sealant, so the old bead is cut away. Nothing else gives a bond that lasts.

Our process

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and we clear our waste as we work. If others near Well End need work, visits can be combined. A fixed quote is given before anything starts.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  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.

Preparing the site

  • Point out any areas we must not close
  • Have the specification and drawings to hand
  • Arrange parking or a loading space

Get a fixed quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or email drawings and photos.

Advice

Cost factors for facade joints

To price the job, we consider:

  • Whether old sealant has to be cut out first
  • Working within restricted access windows
  • Any access equipment needed
  • How much there is to seal

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

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Specification clauses that apply
  • What the building is and how it’s used
  • Clear photos of the problem areas
  • Asbestos survey details if the building is older

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Facade sealing around Well End: what changes locally

At about 27 miles from central London, Well End is within reach of the capital. 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. Well End 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 external mastic is timed for workable conditions and agreed with the site manager.

Projects at schools like Claytons Primary School work to term dates, so mastic is programmed tightly. Recladding or extending a unit at a site like Soho Mills Industrial Estate, 1.1 miles east of Well End, brings panel joints and frame perimeters into the programme.
