Common questions from Cross Gate clients
Is a hospital such as Arundel and District Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you take on work at estates like Quell Farm Industrial Estate, close to Cross Gate?
Yes. Our area takes in Cross Gate and its surroundings, with estates and business parks such as Quell Farm Industrial Estate included. Photos and a short description are enough for a first look.
Can you work to our specification?
We follow the specified sealant, and we’ll raise it if something in it doesn’t suit the joint. Specifications often reference BS EN 15651 or BS 6213.
Does weather affect external mastic work?
Weather matters for external sealing: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
Can you clear a mastic snag list before handover?
Yes. Damaged, missed or untidy joints are stripped and done again properly, working to your handover date.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do your applicators hold CSCS cards?
Our applicators hold CSCS cards, and we are CHAS accredited and a Constructionline member. We are also fully insured, with five million pounds of public liability cover.
How we handle construction mastic in Cross Gate
Site managers want applicators who turn up with the right cards and paperwork. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card, and we’re fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. Site teams most often ask us about sealant knocked or painted over by other trades and failed sealant in an existing building being refurbished, on brick and block movement joints, window and door perimeters and floor and skirting junctions. Most enquiries from Cross Gate start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Around smaller places like Cross Gate, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Leave it or put it right?
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. Snagging can be priced as a separate stage. Around Cross Gate, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
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’ll explain how it’s made up.
Why appoint us
- A fixed quote before work starts
- Old sealant cut out, never sealed over
- Colours confirmed for the specified product
- Coloured sealants to suit the setting, where available

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Common problems we fix in Cross Gate
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. Better to raise it at the start than seal a joint that’s bound to fail.
Common reasons buildings call us in:
- Snag items on joints that need redoing before handover
- Cracks opening in caulked internal joints
- Early adhesion failures on new external joints
- Window and door perimeters that won’t pass inspection
Hospital estates such as Arundel and District Hospital (to the south-west of Cross Gate) 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.

New build and refits around Cross Gate
Rainfall across the South East, Cross Gate included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.

How the job changes by surface
Window and door perimeters
Internal perimeters are normally sealed with a paintable product where decorating follows. The specification decides which.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. Snagging can be included or priced separately, depending on what suits the programme.
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and we clear our waste as we work. Jobs in and around smaller places like Cross Gate are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site
- Flag any permit to work we’ll need
- Tell us which areas need to stay in use
