Facade sealing for commercial buildings in Portfield
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. If you have hard, chalky sealant that no longer flexes and discoloured or dirty facade joints, we can put it right, on coping and flashing joints, cladding panel joints and shopfront frames alike. One point of contact handles commercial sealant work in Portfield from the first photos to the final walk-round, for single jobs and planned programmes alike.
Around places like Portfield, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.

Different surfaces, different methods
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod, primed where the maker specifies.
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, and mask the edges carefully.
What we can’t put right
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Providing access systems for the work
- Movement beyond what any sealant can handle
- Render or concrete edges that have broken away
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Sites and facades in and around Portfield
The area within 2 miles of Portfield holds several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. Portfield is about 54 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.
Recladding or extending a unit at a site like St James Industrial Estate., less than half a mile north of Portfield, brings panel joints and frame perimeters into the programme. Hospital estates such as St Richard's Hospital, 0.6 miles to the north-west of Portfield, 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.

Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Diagnose, treat, sign off
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. For a site in Portfield, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We start with photographs, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full.
- 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.
Getting the site ready
- Tell us what induction or permit system the site runs
- Tell staff and tenants when we will be in
- Arrange parking or a loading space

Advice
When to call us in Portfield
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.
Look out for the following:
- Discoloured or dirty facade joints
- Perimeter joints where frames meet the structure
- Leaks at window and door perimeters
- Hard, chalky sealant that no longer flexes
For contractors at a college like Chichester College, 1.2 miles west of Portfield, perimeters and internal sealant are timed for the holidays.

Questions we are asked in Portfield
Is Portfield too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can work at a site such as University of Chichester fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What hours do you work?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Can you work on upper floors?
Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we’ll price the work around it.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Record the product and colour used on each elevation
- Inspect facade joints on a regular cycle
- Keep pressure washers away from fresh sealant
- Share access with other external trades
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
