How the job changes by surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area and damaged joints are redone rather than patched.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. We use the specified perimeter sealant, usually a low-modulus neutral-cure silicone, with backing rod in deeper gaps.
About our construction mastic in Chilham
Perimeter sealing outside needs a dry joint and the right temperature. 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 areas can normally carry on while the outside waits. We work on brick and block movement joints, sanitary and kitchen joints and floor and skirting junctions, and the failures we’re asked to look at most are sanitary sealant damaged by following trades and old sealant on a refurbishment that needs stripping before new work. Whether you call it commercial sealant work, mastic application or joint sealing, in Chilham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In the countryside around places like Chilham, 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 usually what’s needed.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

If others near Chilham need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

Questions we’re asked in Chilham
Is a smaller place like Chilham outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Does your area include sites such as CMA Industrial Park, near Chilham?
Yes. We cover Chilham and the area around it, including industrial estates, business parks and retail parks such as CMA Industrial Park. A few photos and the unit address let us price the work.
Do your applicators hold CSCS cards?
We are CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. We are fully insured for public liability.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you guarantee new-build sealant work?
Our workmanship carries a 12-month guarantee from sign-off. Damage by others after we’ve finished isn’t covered.
Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Don’t force external sealing on a damp or frosty day
- Bring the mastic contractor in after the last trades are through
- Keep finished joints away from paint, plaster and scrapers
- Brief the final clean team to avoid blades near sealant
Record which products went where in the handover file. That helps the building owner maintain the joints later and avoids guesswork when joints are renewed. Tell us what records you need and we will confirm with the quote.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work, so we plan external work with that in mind.
Do you need construction mastic in Chilham?
Dust is the enemy of adhesion on a construction site. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
What tends to prompt an enquiry:
- Sealant knocked or painted over by other trades
- Mastic snags holding up handover
- Different trades sealing to different standards
- Window and door perimeters that won’t pass inspection
Extensions at sites like Kent and Canterbury Hospital, 5.3 miles to the east of Chilham, normally sit beside working departments, and the mastic follows strict access rules.

For managing agents and facilities managers

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we’ve sealed
- Frames fitted out of tolerance
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly.

Construction mastic in Chilham: the local picture
Rainfall across the South East, Chilham included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Chilham is about 49 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
When units on a site such as CMA Industrial Park, 2.8 miles north-east of Chilham, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Chilham is about 5 miles south-west of Canterbury, in Kent. Across the CT4 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 931 places in Kent, large and small. We also cover London, some 49 miles away.
