Facade sealing for Cripp's Corner sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

About our facade sealing in Cripp's Corner

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. We work on shopfront frames, window and door perimeters and coping and flashing joints, and the usual reasons a site gets in touch are failed sealant on precast panel joints and perimeter sealant that has split or peeled away. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Cripp's Corner, that means joint design, primers and backing rod as standard.

Conversions of older rural buildings near smaller places such as Cripp's Corner bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Surface by surface

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair before sealing.

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex.

Cripp's Corner: questions and answers

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

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Cripp's Corner too far out for you?

Not at all. Cripp's Corner 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.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

How much does the work cost?

There isn’t a price list, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Aftercare for building managers

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

  • Brief window cleaners about newly sealed joints
  • Plan facade sealing alongside redecoration
  • Clear debris that holds water against joints
  • Keep the sealant details on the building file

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

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Arranging specialist high-level access, which is planned with the client
  • Movement beyond what any sealant can handle
  • Damaged frames that need replacing

If you are not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Where we work in Cripp's Corner

  • Perimeter joints where frames meet the structure
  • Shopfront frames
  • Window and door perimeters
  • Stone and brick facade joints
  • Cladding panel joints
  • Coping and flashing joints

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

How a job runs

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. Then we strip out anything that has failed, prepare every joint and seal it. If others near Cripp's Corner need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work 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. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready

  • Tell us your opening times and when work is allowed
  • Warn occupants and staff about the work
  • Send any specification or drawings in advance

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Building and refurbishing in Cripp's Corner

Cripp's Corner is about 46 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Cripp's Corner is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.

With historic properties like Durhamford Manor, 1.5 miles to the south of Cripp's Corner, in the area, refurbishment work often meets old masonry that needs compatible sealants. Extensions at sites like Conquest Hospital, 5.6 miles south of Cripp's Corner, typically sit beside working departments, and the mastic follows strict access rules.

Cripp's Corner is about 7 miles north of Hastings, in East Sussex.

Do you need facade sealing in Cripp's Corner?

Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.

Most enquiries start with one or more of the following:

  • Sealant pulling away from frames or panels
  • Staining on stone next to old sealant
  • Previous reseals run over old sealant
  • Perimeter joints where frames meet the structure

When units on a site such as Vinehall Business Centre, 1.3 miles south-west of Cripp's Corner, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Before you book anyone

  • Will CSCS-carded applicators be on site?
  • What level of public liability insurance do they hold?
  • Whether old or failed sealant will be cut out, not overlaid
  • What the guarantee covers, and for how long
