Construction mastic for Radfall sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Owners, agents and contractors
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
How we handle construction mastic in Radfall
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place. If you’re dealing with early adhesion failures on new external joints and perimeter gaps outside the sealant’s range, we can help, on internal decorators’ caulk, brick and block movement joints and cladding and panel joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Radfall, preparation and product choice get the time they need.
In the countryside around places like Radfall, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Facades, frames and programmes in Radfall
Radfall is within about 2 miles of the coast. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. Central London is about 51 miles from Radfall. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.
Recladding or extending a unit at a site like Joseph Wilson Industrial Park, 1.2 miles north-west of Radfall, brings panel joints and frame perimeters into the programme. Hospital estates such as Whitstable and Tankerton Hospital (1.7 miles north-west of Radfall) 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.
Radfall is about 2 miles south-east of Whitstable, in Kent. Across the CT5 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

- Joint design decisions that belong to the architect or engineer
- Approving fire stopping as compliant
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Should maintenance staff do it?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Common questions from Radfall clients
Is hospital work, at somewhere like Whitstable and Tankerton Hospital, something you do?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can work at a site such as University of Kent fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Are you CHAS accredited?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. We confirm any paperwork you need with the quote.
Can you work plot by plot or floor by floor?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready, and we will raise anything that holds the work up.
Do you use the sealant named in the specification?
The specified product is what goes in. If we think an alternative would suit better, we put it to you first.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
When to call us in Radfall
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.
Site and facilities staff are often the first to spot these:
- Internal caulk splitting as the building dries out
- Window and door perimeters that won’t pass inspection
- Mastic snags holding up handover
- Perimeter gaps outside the sealant’s range
When a school such as The Whitstable School is extended or refurbished, the mastic package is often squeezed into the holidays.
Questions to ask before you book
- Their public liability cover
- How the existing material will be dealt with
- How they’ll work around occupants
- How long is the guarantee, and what does it include?
What happens if it’s left?
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. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Halls, stores and units around places like Radfall may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
