FAQs: Sweethaws
Is hospital work, at somewhere like Crowborough War Memorial Hospital, something you do?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Is Sweethaws off your patch?
No. Places such as Sweethaws are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Should we check old sealant for asbestos?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register. Suspect material is left alone until it has been tested.
Can the building stay open while you work?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. Most enquiries involve cladding panel joints that have opened up and weathered joints at frame-to-structure perimeters, on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure.

Mastic packages on Sweethaws sites
Sweethaws sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Sweethaws lies roughly 34 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
For a contractor working at a hospital such as Crowborough War Memorial Hospital, which lies north-east of Sweethaws, perimeter and facade sealing is planned around patients and deliveries. Projects at schools like Beacon Academy work to term dates, so mastic is programmed tightly.
Sweethaws is about 2 miles south-west of Crowborough, in East Sussex. Businesses, contractors and managing agents in Sweethaws can call on us for facade joints. Sweethaws is one of 308 places we cover in East Sussex. Sites around Brighton have their own page, about 18 miles away.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Render or concrete edges that have broken away
- Work on the window or framing system itself
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
Surfaces we seal
- Cladding panel joints
- Coping and flashing joints
- Shopfront frames
- Perimeter joints where frames meet the structure
- Stone and brick facade joints
- Window and door perimeters
On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. If others near Sweethaws need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Let us know about inductions and permits
- Let building users know which areas are affected
- Have the specification and drawings to hand

When to bring in a 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: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Avoid harsh cleaners on facade sealant
- Combine resealing with other works that need access
- Keep the sealant details on the building file
- Report water ingress at frames as soon as it shows
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.
Cost factors for facade joints
What shapes the price:
- How much existing material needs removing
- How accessible the joints are
- Site requirements such as inductions and permits
- How much there is to seal
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Where the site is, with the postcode
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
- When you need the work done
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or email the details over.
What we are called out for in Sweethaws
The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Clients normally get in touch after noticing one or more of the following:
- Weathered joints at frame-to-structure perimeters
- Leaks at window and door perimeters
- Unsightly perimeter sealant on a visible elevation
- Gaps between rainscreen or cladding panels
When units on a site such as Windsor Business Park, 2 miles to the east of Sweethaws, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
What your quote should include
- Will failed sealant be removed rather than covered?
- How the joint faces will be prepared and primed
- How they handle RAMS and site documents
- Can the work be phased to keep areas open?
