Why deal with it now?
It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification, which avoids last-minute problems. Leave it late and they turn up on the snag list. Around Avon Castle, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
Pricing mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Why appoint us
- CSCS-carded applicators
- Standard and matched colours in many product ranges
- Products installed to the manufacturer’s instructions
- Colours confirmed for the specified product
About our construction mastic in Avon Castle
Mastic is often where a new building first shows its quality to the client. Untidy or missed joints are among the commonest snag items and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, area by area through the programme. If you have sealant knocked or painted over by other trades and internal caulk splitting as the building dries out, we can help, whatever the surface. A single leaking joint is often how a building in Avon Castle 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.
For a site near Avon Castle, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Maintenance after handover
To get the most from the new sealant:
- Keep finished joints away from paint, plaster and scrapers
- Stick to the specified sealant rather than a generic substitute
- Flag uneven or tapered frame gaps early
- Plan external elevations with the weather in mind
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known, and tells you what to reseal with. Tell us what records you need and we will confirm with the quote.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels. Getting the product and preparation right first time avoids that.
Diagnose, treat, sign off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Smaller jobs around Avon Castle can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

Surface by surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services, and we will tell you if the detail calls for something else. Tell us what records you need and we’ll confirm with the quote.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.

What else we do in Avon Castle
When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Rework caused by others damaging completed areas
- Faulty frames rather than failed sealant
- Frame gaps too wide for sealant, which the installer needs to correct
If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
What we seal
- Brick and block movement joints
- Cladding and panel joints
- Floor and skirting junctions
- Window and door perimeters
- Sanitary and kitchen joints
- Internal decorators’ caulk
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Mastic packages on Avon Castle sites
Rainfall across the South East, Avon Castle included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. A number of hotels sit less than 2 miles from Avon Castle. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
For contractors refurbishing units at places like Millstream Trading Estate, 1.2 miles to the north-east of Avon Castle, the mastic covers cladding panels, roller-door and window perimeters. When a college such as Sheiling College (0.9 miles north of Avon Castle) builds or refurbishes, the mastic package usually has to fit around students and staff. Work at a hotel such as St Leonards Hotel (to the west of Avon Castle) tends to be programmed around bookings, mastic included.

Your questions answered
Is hospital work, at somewhere like St Leonards Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work around term dates at a campus such as Sheiling College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can staff carry on working while you’re here?
In most cases, yes. Phased work can be planned so areas stay in use.
Can you work plot by plot or floor by floor?
We seal plot by plot or floor by floor as areas are released. The sequence is settled with your site team.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
