Owners, agents and contractors
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Sompting can sit alongside others in a wider programme.
How we handle construction mastic in Sompting
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal areas can typically carry on while the outside waits. We work on floor and skirting junctions, sanitary and kitchen joints and cladding and panel joints, and the usual reasons a site gets in touch are a long mastic snag list close to completion and internal caulk splitting as the building dries out. A single leaking joint is often how a building in Sompting first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
On a small site around Sompting, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

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:
- Faulty frames rather than failed sealant
- Designing joint widths or choosing the specification (that sits with the designer)
- Deciding which fire-stopping product a penetration needs
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Cladding and panel joints
- Window and door perimeters
- Sanitary and kitchen joints
- Floor and skirting junctions
- Internal decorators’ caulk
- Brick and block movement joints
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Brief the final clean team to avoid blades near sealant
- Flag uneven or tapered frame gaps early
- Keep finished joints away from paint, plaster and scrapers
- Plan external elevations with the weather in mind
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We raise them during our first walk of the area.

Mastic packages on Sompting sites
Sompting sits close to the coast, within about 2 miles. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. A 2-mile radius around Sompting takes in several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
For contractors at a school such as Sompting Village Primary School, sealing has to be finished before term starts. Projects at colleges like Northbrook College (1.7 miles west of Sompting) tend to run to term dates, so the mastic is planned tightly.

Your questions answered
Is hospital work, at somewhere like Worthing Hospital, something you do?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does a coastal location like Sompting affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Can you quote from photographs?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Can you work plot by plot or floor by floor?
Our work is sequenced around the programme. Areas are sealed as they’re released by the site team.
Can you seal external joints in wet or cold weather?
External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work.
What we’re called out for in Sompting
On construction sites, joints usually fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
Most enquiries start with one or more of the following:
- A mastic package split between trades with no clear owner
- Caulk cracking where joints are moving more than expected
- Window and door perimeters that won’t pass inspection
- New external sealant already peeling away
On a healthcare site such as Worthing Hospital (1.6 miles south-west of Sompting), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What to look for in a quote
- Whether primer will be used where the manufacturer specifies it

- Their public liability cover
- Is the sealant right for the movement and the substrate?

Why it’s worth doing now in Sompting
Sealing over damaged or contaminated new joints might save a day, but it won’t last. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. We cut out and redo the joint properly. For buildings in places like Sompting, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
