From enquiry to sign-off

Facade sealing for commercial buildings in Halnaker
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. We work on shopfront frames, perimeter joints where frames meet the structure and window and door perimeters, and the failures we are asked to look at most are perimeter sealant that has split or peeled away and damp patches beside frames after rain. Most enquiries from Halnaker start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in and around smaller places such as Halnaker is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Maintenance after handover
To get the most from the new sealant:
- Share access with other external trades
- Keep pressure washers away from fresh sealant
- Note when each elevation was last resealed
- Ask about asbestos in pre-2000 mastic
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.
FAQs: Halnaker
Can you work on a hospital site such as St Richard's Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Mastic packages on Halnaker sites
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 external mastic is timed for workable conditions and agreed with the site manager. Halnaker has several hotels close by, all within 2 miles. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
For contractors refurbishing units at places like Chichester Business Park., 0.9 miles south of Halnaker, the mastic covers cladding panels, roller-door and window perimeters. For a contractor at a hotel such as The Richmond Arms Hotel, which lies west of Halnaker, the mastic often has to be finished before a reopening date.
Halnaker is about 3 miles north-east of Chichester, in West Sussex. Anywhere in PO18, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our West Sussex coverage takes in 373 places, from busy centres to rural villages. We also cover Portsmouth, around 16 miles from Halnaker.

Local landmarks in Halnaker

Common problems we fix in Halnaker
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.
Most enquiries start with one or more of the following:
- Water coming in around window frames
- Failed sealant on precast panel joints
- Perimeter sealant that has split or peeled away
- Weathered facade joints that have lost their grip
For contractors on a campus like University of Chichester, 3 miles to the south-west of Halnaker, facade and perimeter sealing has to fit around students and term dates.

How the job changes by surface
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification.
Precast concrete panels
Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.

What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Joints whose design needs changing by the specifier
- Specialist high-level access methods
- Work on the window or framing system itself
If in doubt, phone 01277 525 020 or send photos by email and we’ll say what we think before you book.
Surfaces we seal
- Stone and brick facade joints
- Cladding panel joints
- Coping and flashing joints
- Shopfront frames
- Window and door perimeters
- Perimeter joints where frames meet the structure
General trades versus a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
