Facade sealing across West Sussex: what to expect

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. If the evidence points away from the sealant, we say so before quoting. The enquiries we see most involve old perimeter mastic that has dried out and leaks at window and door perimeters, on perimeter joints where frames meet the structure, stone and brick facade joints and coping and flashing joints.

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in.

Photos, drawings or a visit tell us about the joints and the access.
We confirm the joint type, movement and the specified product.
The existing bead comes out in full and both faces cleaned back.
Primer goes on where the product data asks for it.
Rod goes in to fix the depth, then the joint is sealed and tooled.
The finished joints are checked with you.

What you will pay

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Facade sealing across West Sussex: the area picture

From Crawley, Horsham and Worthing to smaller places across West Sussex, main contractors and developers need mastic packages for new build and refurbishment. Window and door perimeters, facade and cladding joints and internal sealant are sealed to the specification and the programme.

London and the South East are among the drier parts of the UK, but external sealing in West Sussex still needs a dry joint and the right temperature, and damp or frosty mornings can hold it up. West Sussex includes coastal places, where facades, frames and external slabs take more weather than inland. Product choice and joint preparation matter more there.

Crawley: Further education sites such as Crawley College, 0.5 miles to the north-east of Crawley, are extended and refurbished from time to time, with mastic often programmed into the summer break. Hospital estates such as Crawley Hospital (0.5 miles north-west of Crawley) 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.

Aftercare for building managers

To get the most from the new sealant:

Insist on a full cut-out when joints are renewed
Add perimeter sealant to planned maintenance checks
Keep sills, gutters and drainage paths clear
Share access with other external trades

Following storms, look inside for damp or staining near frames. An early report usually means a small reseal rather than a bigger repair.

Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading behind the facade.

Why act early?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak.

How long is the guarantee, and what does it include?
Health and safety accreditation such as CHAS
Whether old or failed sealant will be cut out, not overlaid
What site paperwork they can supply

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Signs you need facade sealing

Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.

Most enquiries start with one or more of the following:

Air leaks through failed facade joints
Weathered joints at frame-to-structure perimeters
Old perimeter mastic that has dried out
Sealant pulling away from frames or panels

Surface by surface

Render and coated surfaces

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

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported.

Questions we’re asked in West Sussex

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Can you work on upper floors?

That varies with the building and the access on offer. When you ring 01277 525 020 or send photos by email, describe the access, and we’ll plan the work with you.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
