Contractors’ notes for Avisford
Avisford is about 50 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. Several hotels sit less than 2 miles from Avisford. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
University estates such as University of Chichester (Bognor Campus) (4.7 miles south-west of Avisford) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Recladding or extending a unit at a site like Tokar Industrial Park, 0.8 miles south of Avisford, brings panel joints and frame perimeters into the programme.

Construction mastic in Avisford
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal areas can typically carry on while the outside waits. Most enquiries involve frame gaps too wide for sealant alone and caulk cracking where joints are moving more than expected, on brick and block movement joints, internal decorators’ caulk and floor and skirting junctions. Facilities teams, main contractors and managing agents in Avisford tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions of older rural buildings near smaller places such as Avisford bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Allow flexibility for external sealing in damp or cold weather
- Share drawings and the specification as soon as possible
- Brief following trades on areas that have been sealed
- Keep scrapers and abrasive pads off new beads
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, 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, so the installer needs to correct it first. We flag them as soon as we see them.
When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Deciding which fire-stopping product a penetration needs
- Damage to finishes by other trades after we’ve sealed
- Glazing units that are cracked or misted
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Common problems we fix in Avisford
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Any of the following is a good reason to get the joints checked over:
- Frame perimeters left unsealed or poorly sealed
- Early adhesion failures on new external joints
- Frame gaps too wide for sealant alone
- Internal caulk splitting as the building dries out
Extensions at sites like Arundel & District Community Hospital, 2.1 miles east of Avisford, usually sit beside working departments, and the mastic follows strict access rules.

Advice
Avisford: questions and answers
Can you work around term dates at a campus such as University of Chichester (Bognor Campus)?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you cover business parks and estates near Avisford, such as Tokar Industrial Park?
Yes. Our area takes in Avisford and its surroundings, with estates and business parks such as Tokar Industrial Park included. Photos and a short description are enough for a first look.
What joints do you seal on a new build?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging in one fixed quote.
What happens if the weather stops external sealing?
Weather matters for external sealing: the joint needs to be dry and within the product’s temperature range. External work is sequenced with some flexibility.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
What accreditations do you hold?
Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. We’re also fully insured, with five million pounds of public liability cover.
Why deal with it now?
When a package runs over budget, downgrading the product is a common first thought. A failed joint in the defects period costs far more than the product difference and external joints are where it shows first. Where an alternative is genuinely suitable, we’ll say so. One visit to deal with every failing joint makes more sense than several trips to a place like Avisford. Photos of every joint help us quote for the whole job.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What you get with us
- Old sealant cut out, never sealed over
- A range of standard colours, depending on the product
- Colours confirmed for the specified product
- One phone line for London, the South East and Scotland
Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
