Need facade sealing in Hightown?

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

Common problems we fix in Hightown

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.

Most enquiries start with something like this:

  • Leaks at window and door perimeters
  • Hard, chalky sealant that no longer flexes
  • Perimeter joints where frames meet the structure
  • Air leaks through failed facade joints

When a school such as Ringwood Junior School is extended or refurbished, the mastic package is often squeezed into the holidays.

What your quote should include

  • How they’ll work around occupants
  • Proof of insurance
  • How they handle RAMS and site documents
  • Will failed sealant be removed rather than covered?

Questions to ask before you appoint anyone

How we handle facade sealing in Hightown

Managing agents and owners in Hightown ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. If you have damp patches beside frames after rain and draughts around frames and panels, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Hightown, preparation and product choice get the time they need.

For a site near Hightown, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Different surfaces, different methods

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building and need a durable external sealant.

Cladding panel joints

Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a day or two for a few elevations, and longer where access has to be moved around the building. If others near Hightown need work, visits can be combined. A fixed quote is given before anything starts.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  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.

Preparing the site

  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot
  • Share the asbestos register for older buildings

Advice

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

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.

Hightown: questions and answers

Can you work at a site such as Platinum Jubilee Business Park, by Hightown?

Yes, sites like Platinum Jubilee Business Park are within our area, along with the rest of Hightown. Send details of the unit and the work through our quote form for a quick quote.

Is a smaller place like Hightown outside your area?

Not at all. Hightown is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you seal facades in winter?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, and we build that into the programme.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

How long does a job like this take?

It depends on the scope, but the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we’ll set out a timescale with the quote.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Facades, frames and programmes in Hightown

Hightown 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, which is why external dates are agreed with the site manager. Several hotels sit less than 2 miles from Hightown. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

For a contractor at a hotel such as The Crown Hotel, which lies west of Hightown, the mastic often has to be finished before a reopening date. On a healthcare site such as St Leonard's Hospital, which lies south-west of Hightown, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Aftercare for building managers

Problems stay small when the joints are checked regularly. In particular:

  • Check the asbestos register before old mastic is disturbed
  • Brief window cleaners about newly sealed joints
  • Clear debris that holds water against joints
  • Insist on a full cut-out when joints are renewed

Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.

Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.
