About our facade sealing in Sidlesham

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. If you have cladding panel joints that have opened up and perimeter joints where frames meet the structure, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Sidlesham, preparation and product choice get the time they need.

For a site near Sidlesham, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or send photos by email and we’ll arrange a return visit.

Aftercare for building managers

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Insist on a full cut-out when joints are renewed
  • Report water ingress at frames as soon as it shows
  • Walk the elevations once or twice a year
  • Avoid harsh cleaners on facade sealant

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.

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.

Our process

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 anything is cut or cleaned, with the work itself typically taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Jobs in and around smaller places like Sidlesham are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Point out any areas we must not close
  • Arrange parking or a loading space

Ask for a quote

Advice

Different surfaces, different methods

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint.

Questions about Sidlesham

Could you schedule work at a campus like University of Chichester for the vacation?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Sidlesham too small for you to travel to?

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

Can you work on upper floors?

Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Will rain stop the work?

Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.

Is any job too small?

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

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.

Site staff or a sealant specialist?

Some joints are best left to specialists: 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.

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.

Quoting for work in Sidlesham

To price the job, we consider:

  • Backing rod, priming and other preparation
  • Site requirements such as inductions and permits
  • Working within restricted access windows
  • How accessible the joints are

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

However big the job, these details speed things up:

  • Whether the building will be occupied during the work
  • Clear photographs of the problem areas
  • The site address and postcode
  • Your programme or deadline

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Common problems we fix in Sidlesham

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back.

Typical triggers for a call:

  • Perimeter sealant that has split or peeled away
  • Failed seals around shopfront and entrance frames
  • Hard, chalky sealant that no longer flexes
  • Patch repairs that keep failing

Projects at schools like Sidlesham Primary School work to term dates, so mastic is programmed tightly.

Questions to ask before you book

  • Can the work be phased to keep areas open?
  • Who will actually carry out the work
  • What site paperwork they can supply
  • Their approach to joint depth and backing

Questions to ask before you appoint anyone

Mastic packages on Sidlesham sites

With the shore within about 1 mile, Sidlesham counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Sidlesham is about 58 miles from central London. 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.

Building work at universities like University of Chichester, 4.1 miles north-east of Sidlesham, is often timed for the summer, mastic included. When units on a site such as Enborne Business Park, 0.8 miles to the south of Sidlesham, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
