How we handle construction mastic in Arundel
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 it helps to sequence elevations with some flexibility. Internal sealing often fills those days. We work on sanitary and kitchen joints, cladding and panel joints and internal decorators’ caulk, and what we’re called in for most is missed perimeter joints on a new elevation and bath and shower joints scraped during the final clean. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Arundel it comes down to the same thing: the right product in a properly prepared joint.
Building work in places the size of Arundel is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we’ll come back to it.

Commercial clients in Arundel
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Why it’s worth doing now in Arundel
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go and saves applicators coming back again and again. Snagging can be priced as a separate stage. Small buildings around Arundel suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Rework caused by others damaging completed areas
- Frame gaps too wide for sealant, which the installer needs to correct
- Joint design decisions that belong to the architect or engineer
Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Surfaces we seal
- Cladding and panel joints

- Floor and skirting junctions
- Brick and block movement joints
Common problems we fix in Arundel
Most mastic snags on new buildings come from sequencing rather than product. 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:
- Window and door perimeters that won’t pass inspection
- External joints sealed in damp or cold conditions that are now failing
- Frame gaps too wide for sealant alone
- Sealant knocked or painted over by other trades
For a contractor working at a hospital such as Arundel & District Community Hospital (less than half a mile north-west of Arundel), perimeter and facade sealing is planned around patients and deliveries.
What your quote should include

Your questions answered
Can you work at a site such as The Vinery Industrial Estate, by Arundel?
Yes. Estates, retail parks and business parks around Arundel, The Vinery Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Would you work within a site like Arundel & District Community Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
What does a mastic package normally include?
Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. The scope follows your specification.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What accreditations do you hold?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. Tell us what site paperwork you need and we will confirm with the quote.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact.
Construction mastic in Arundel: the local picture
Central London is about 49 miles from Arundel. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Arundel sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
Hotel extensions and refits, at places such as The Norfolk Hotel, less than half a mile east of Arundel, typically run between busy periods, so the sealing is squeezed into short windows. Projects at schools like St Philip's Catholic Primary School work to term dates, so mastic is programmed tightly.

Advice
Maintenance after handover
After handover, these steps help:
- Release areas for mastic once other trades have finished in them
- Put any product change through the designer first
- Note which sealant went where at handover
- Allow flexibility for external sealing in damp or cold weather
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
