FAQs: Radfield
Can you work on a hospital site such as Sittingbourne Memorial Hospital?
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.
Is Kent Science Park, near Radfield, within your area?
Yes. Our area takes in Radfield and its surroundings, with estates and business parks such as Kent Science Park included. A few photographs and the unit address let us price the work.
Are you insured?
Yes. We’re fully insured, including public liability cover.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you do fire-rated sealing on new builds?
We install fire-rated sealant where it is the specified product. We’ll flag if the detail needs a different product.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Can you work plot by plot or floor by floor?
Working to your programme, we seal each area as it’s handed over. The sequence is settled with your site team.
Construction mastic in Radfield, done properly
Mastic tends to be one of the final packages before handover, which puts it right on the critical path. We work as a mastic subcontractor to main contractors and developers with projects in Radfield, following the trades through the building as rooms and elevations become ready. If you’re dealing with snag items on joints that need redoing before handover and bath and shower joints scraped during the final clean, we can put it right, on sanitary and kitchen joints, window and door perimeters and internal decorators’ caulk alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Radfield, preparation and product choice get the time they need.
Conversions of older rural buildings near smaller places such as Radfield bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Radfield need work, visits can be combined. A fixed quote is given before anything starts.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Preparing the site

Advice
What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Designing joint widths or choosing the specification (that sits with the designer)
- Faulty frames rather than failed sealant
- Damage to finishes by other trades after we’ve sealed
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly before you book.
Surfaces we seal
- Brick and block movement joints
- Window and door perimeters
- Cladding and panel joints
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Floor and skirting junctions

Facades, frames and programmes in Radfield
Radfield lies within about 3 miles of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Radfield lies roughly 40 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
Further education sites such as KITE College, 1.9 miles north-west of Radfield, are extended and refurbished from time to time, with mastic often programmed into the summer break. School extensions, at buildings such as Teynham Parochial Church of England Primary School, usually run to the summer holidays, mastic included.

Why it’s worth doing now in Radfield
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. One mastic subcontractor for the lot keeps it simple. Around Radfield, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
A quote for 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 choose Mastic Doctor in Radfield
- A range of standard colours, depending on the product
- Work to your specification and the manufacturer’s guidance
- Joints cleaned back to sound surfaces
- Colours chosen to suit frames, cladding or finishes where possible
What we’re called out for in Radfield
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink. Picking a flexible sealant where there’s movement keeps snags down.
Things that normally lead to an enquiry:
- Frame perimeters left unsealed or poorly sealed
- Frame gaps too wide for sealant alone
- Early adhesion failures on new external joints
- Sanitary sealant damaged by following trades
For a contractor working at a hospital such as Sittingbourne Memorial Hospital, 2.1 miles to the west of Radfield, perimeter and facade sealing is planned around patients and deliveries.
What to look for in a quote
- How they’ll work around occupants

Cost factors for mastic packages
Your fixed quote is built from the real scope. It takes account of:
- Phasing around occupants
- Induction, permit and paperwork requirements
- How much there is to seal
- Distance, for remote addresses
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- When you need the work done
- Photos of the joints, close up and from further back
- The site address and postcode
- How the joints are reached, and at what height
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or email a schedule or drawings.
Surface by surface
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.
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere, plot by plot or floor by floor.
