Questions we are asked in Boxgrove
Can you work in a care home near Boxgrove with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Do you work for managing agents with blocks near Chichester station?
Yes, and several blocks can go on one quote. We work to your notice and access arrangements.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
Mastic sealing for commercial buildings in Boxgrove
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. If you’re dealing with water getting in round frames after rain and brittle perimeter mastic across a building, we can put it right, on external wall and movement joints, window and door perimeters on blocks and communal kitchens and washrooms alike. For commercial sealant work in Boxgrove, you deal with one contact from quote to sign-off, whether it’s one building or several.
In and around smaller places like Boxgrove, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Whoever the client is, the cover is the same: 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.

- Working within restricted access windows
- Which sealant the job calls for
- Any access equipment needed
- The site’s rules and procedures
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you’re ready.
Sending details for a quote
To price the job accurately, we need to understand the site. Send us:
- Drawings or a marked-up plan, if available

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or use the quote form to discuss it first.
Mastic sealing around Boxgrove: points for this area
Two care or nursing homes sit less than 2 miles from Boxgrove. Care home owners need frame and external mastic kept sound without unsettling residents. Boxgrove is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you look after a block within reach of Chichester station, 3.5 miles south-west of Boxgrove, frame and balcony mastic can be renewed on one programme. Churches, halls and community buildings such as The Priory Church of St Mary and St Blaize are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Boxgrove is about 3 miles north-east of Chichester, in West Sussex. Businesses, contractors and managing agents in Boxgrove can call on us for mastic joints. 373 places across West Sussex fall within our area, Boxgrove among them. Sites around Portsmouth have their own page, about 16 miles away.

What’s near Boxgrove
Locally, jobs take us to sites close to Ormiston Six Villages Academy and The Winterton Arms Public House, among other places. The closest station to Boxgrove is Chichester station, roughly 3.5 miles south-west of the centre. A little further out are Chichester Centre (2.7 miles west) and Tote Copse Castle (1.9 miles south-east). Green spaces nearby include Levin Down.
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Reduce knocks to communal area joints
- Ask residents or tenants to report leaks and draughts early
- Prioritise elevations facing the weather
- List the paperwork your organisation requires when you send details
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
One failed perimeter normally means others on the same building are close, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

Advice
Why it’s worth doing now in Boxgrove
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee. One visit to deal with every failing joint makes more sense than several trips to a place like Boxgrove, rather than one at a time. Send photographs of each area and we will quote for the lot.
Pricing mastic joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Different surfaces, different methods
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.
Do you need mastic sealing in Boxgrove?
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We’ll tell you if the joint edges need repairing before resealing.
Clients typically get in touch after noticing one or more of the following:
- Window mastic that has split and shrunk
- Patchy repairs in mismatched sealant
- Leaks at window and door perimeters
- Damaged joints in communal entrances and corridors
For owners of several units at places like Chichester Business Park., 0.5 miles south of Boxgrove, one programme can deal with frame and external mastic across the lot.
