Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Building owners, agents and FMs in Southwater
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Southwater. One quote can cover more than one site, so there’s one set of paperwork to deal with.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
How we handle facade sealing in Southwater
Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. We work on perimeter joints where frames meet the structure, cladding panel joints and shopfront frames, and the failures we are asked to look at most are failed sealant on precast panel joints and discoloured or dirty facade joints. Most enquiries from Southwater start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Conversions around smaller places like Southwater often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.
Work we carry out in West Sussex comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we’ll come back to it.

FAQs: Southwater
Is Southwater Business Park, near Southwater, within your area?
Yes, sites like Southwater Business Park are within our area, along with the rest of Southwater. Photos and a short description are enough for a first look.
Can you take on a job at a hospital such as Horsham Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Is old mastic on our building likely to contain asbestos?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, so ask for it before we start. Suspect material is left alone until it has been tested.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
Can you find out why a window is leaking?
Yes. We look at the perimeter sealant and tell you whether it has failed. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
When something else is needed
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Providing access systems for the work
- Cracked or spalling substrates that need repair before sealing
- Water getting in through cracked render or porous masonry
If you are not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.
What we seal
- Cladding panel joints
- Stone and brick facade joints
- Shopfront frames
- Window and door perimeters
- Coping and flashing joints
- Perimeter joints where frames meet the structure
Signs you need facade sealing in Southwater
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.
Any of the following is a good reason to get the joints checked over:
- Discoloured or dirty facade joints
- Damp patches beside frames after rain
- Weathered facade joints that have lost their grip
- Previous reseals run over old sealant
Extensions at sites like Horsham Hospital (to the north of Southwater) normally sit beside working departments, and the mastic follows strict access rules.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Their public liability cover
- Who will actually carry out the work
- Which product they’ll use, and why it suits the joint
Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Inspect facade joints on a regular cycle
- Never let anyone seal over old sealant
- Brief window cleaners about newly sealed joints
- Keep the sealant details on the building file
Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.
How a job runs
The first thing on site is a walk round with your contact, 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 neighbouring businesses or buildings around Southwater need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- 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.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- 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
- Confirm the product named in the specification
- Warn occupants and staff about the work
- For older buildings, check the asbestos register before work

Advice
Why act early in Southwater
The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Mastic packages on Southwater sites
Southwater lies roughly 34 miles out 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. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
When units on a site such as Southwater Business Park (less than half a mile south-west of Southwater) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For contractors at a school such as Southwater Infant Academy, sealing has to be finished before term starts.
