Facade sealing for Passfield sites

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

General trades versus a specialist

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Facade sealing in Passfield, done properly

Facade sealants sit in the sun, rain and frost every day. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. If you are dealing with water coming in around window frames and sealant pulling away from frames or panels, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Passfield, that means joint design, primers and backing rod as standard.

Around smaller places like Passfield, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Work we carry out in Hampshire comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email a schedule or drawings and we’ll come back to it.

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.

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, and mask the edges carefully.

Facade sealing around Passfield: what changes locally

At about 42 miles from central London, Passfield is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

When units on a site such as Passfield Industrial Estate (to the north of Passfield) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Projects at schools like Mill Chase Academy work to term dates, so mastic is programmed tightly.

Passfield is about 7 miles south-east of Alton, in Hampshire. Looking for facade sealing in Passfield? We can help. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. Portsmouth is covered too, some 23 miles away.

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Insist on a full cut-out when joints are renewed
  • Check the asbestos register before old mastic is disturbed
  • Check that rainwater leaves the facade the way it was designed to
  • Plan facade sealing alongside redecoration

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Passfield, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Have the specification and drawings to hand
  • Tell staff and tenants when we’ll be in
  • Point out parking and an unloading spot

Advice

What we are called out for in Passfield

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.

If one of these sounds familiar, it’s time for a closer look:

  • Sealant pulling away from frames or panels
  • Old perimeter mastic that has dried out
  • Water coming in around window frames
  • New sealant peeling off old mastic

New wings at hospitals like Chase Hospital, 1.5 miles north-west of Passfield, bring long runs of window and panel joints to seal.

  • Their pre-qualification and accreditations
  • Will failed sealant be removed rather than covered?
  • The named product and why it was chosen

Our contractor checklist

Why deal with it now?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Older rural buildings around Passfield move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why appoint us

  • A fixed quote before work starts
  • Constructionline member
  • Work to your specification and the manufacturer’s guidance
  • Fully insured, including public liability cover

Your questions answered

Is a hospital such as Chase Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Is Passfield too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

What site paperwork can you supply?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Will rain stop the work?

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.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
