FAQs: South Mundham
Can work at a site such as University of Chichester fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Is South Mundham off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How is access to upper-level joints handled?
We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.
About our facade sealing in South Mundham
We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. We work on coping and flashing joints, cladding panel joints and window and door perimeters, and the failures we are asked to look at most are staining on stone next to old sealant and leaks at window and door perimeters. Whether you call it commercial sealant work, mastic application or joint sealing, the work in South Mundham is the same: the right product in a properly prepared joint.
For a site near South Mundham, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Facade sealing around South Mundham: how the place shapes the job
With the shore within about 2 miles, South Mundham counts as a coastal location. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. South Mundham sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.
When a college such as West Sussex Alternative Provision College, 1 mile north of South Mundham, builds or refurbishes, the mastic package typically has to fit around students and staff. On a campus such as University of Chichester, 2.1 miles to the north-east of South Mundham, new teaching buildings and residences are typically built and refurbished around the academic year.

What’s near South Mundham
We work on buildings around Chichester High School For Girls and Avisford and the streets around them. The nearest railway station is Chichester station, roughly 2.5 miles north-west of the centre. Other landmarks nearby include Chichester Castle (3 miles north) and Chichester Cathedral Treasury (2.7 miles north-west).
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Check the asbestos register before old mastic is disturbed
- Don’t wait for a second leak before calling
- Combine resealing with other works that need access
- Walk the elevations once or twice a year
Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.
How the job changes by surface
Cladding panel joints
On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them to the correct depth.
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Building owners, agents and FMs in South Mundham
When you manage a building on behalf of an owner, 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.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

What we’re called out for in South Mundham
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.
These are often picked up first by site or facilities staff:
- Staining on stone next to old sealant
- Sealant pulling away from frames or panels
- New sealant peeling off old mastic
- Gaps between rainscreen or cladding panels
Extensions at sites like St Richard's Hospital (3.1 miles north of South Mundham) typically sit beside working departments, and the mastic follows strict access rules.
Before you book anyone
- How the existing material will be dealt with
- Which product they’ll use, and why it suits the joint
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern.
