Our process

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If neighbouring businesses or buildings around Pease Pottage need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. Access, site rules and timing are settled with the client up front.
  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. 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

  • Clear stock, furniture or equipment away from the joints
  • Tell us which areas need to stay in use

Facade sealing in Pease Pottage

Facade sealants sit in the sun, rain and frost every day, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. If you’re dealing with old perimeter mastic that has dried out and perimeter sealant that has split or peeled away, we can put it right, on stone and brick facade joints, window and door perimeters and coping and flashing joints alike. Whoever orders the work in Pease Pottage, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Building work in places the size of Pease Pottage is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

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

What the job involves on each surface

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.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.

Facade sealing in Pease Pottage: the local picture

Pease Pottage sits in or beside Crawley, a twentieth-century planned town. Many of its original buildings are reaching the age for recladding and new windows, with mastic packages to match. Central London is about 29 miles from Pease Pottage. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.

When a college such as Crawley College, 2.3 miles north of Pease Pottage, builds or refurbishes, the mastic package normally has to fit around students and staff. With historic properties like Tyes Place (3.4 miles south of Pease Pottage) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Pease Pottage is about 2 miles south of Crawley, in West Sussex. Our applicators travel to Pease Pottage for work on facade joints, handled exactly as we handle every other area.

Honest limits

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Movement beyond what any sealant can handle
  • Providing access systems for the work
  • Cracked or spalling substrates that need repair before sealing

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What we seal

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

What we are called out for in Pease Pottage

Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Any of the following is a good reason to get the joints checked over:

  • Hard, chalky sealant that no longer flexes
  • Unsightly perimeter sealant on a visible elevation
  • Draughts around frames and panels
  • Leaks at window and door perimeters

Hospital estates such as Crawley Hospital, 2.3 miles to the north of Pease Pottage, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Questions to ask before you book

  • How the existing material will be dealt with
  • Who will actually carry out the work
  • Whether primer will be used where the manufacturer specifies it
  • Their approach to joint depth and backing

Questions about Pease Pottage

Can you take on a job at a hospital such as Crawley Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Can work at a site such as Crawley College fit around teaching?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you install glazing systems?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.

Can you look at water coming in around a frame?

Yes. We check the sealant joints and report what we find. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Do you use silicone for external joints?

The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.

How is access to upper-level joints handled?

That comes down to the access arranged for the job. When you call the office on 01277 525 020 or email us, describe the access, and we’ll plan the work with you.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Check the asbestos register before old mastic is disturbed
  • Keep sills, gutters and drainage paths clear
  • Don’t wait for a second leak before calling
  • Avoid harsh cleaners on facade sealant

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly using a matching sealant.

Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail.
