Why act early in Upper Hardres
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects. Where an alternative is genuinely suitable, we’ll say so. Around Upper Hardres, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
A quote for mastic packages depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.
Why appoint us

Construction mastic in Upper Hardres
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. If you have internal caulk splitting as the building dries out and failed sealant in an existing building being refurbished, we can help, whatever the surface. Searching for sealant specialists in Upper Hardres? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Sites around smaller places like Upper Hardres can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Common problems we fix in Upper Hardres
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.
Common reasons buildings call us in:
- Window and door perimeters that won’t pass inspection
- Failed sealant in an existing building being refurbished
- Inconsistent sealant finishes from plot to plot
- A long mastic snag list close to completion
New wings at hospitals like Kent and Canterbury Hospital, 3.5 miles to the north of Upper Hardres, bring long runs of window and panel joints to seal.

Building and refurbishing in Upper Hardres
Central London is about 54 miles from Upper Hardres. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. Rainfall across the South East, Upper Hardres 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 external mastic is timed for workable conditions and agreed with the site manager.
University estates such as University for the Creative Arts (to the north of Upper Hardres) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Looking after the joints
After handover, these steps help:
- Ask installers to correct oversized gaps first
- Use the product the specification names
- Don’t schedule sealing before decorators and flooring are done
- Keep scrapers and abrasive pads off new beads
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby.
One unsealed frame can let water into finished internal areas. That typically means redoing finishes in a completed area, and a delay to handover. Checking perimeters before internal finishes go on avoids it.

Common questions from Upper Hardres clients
Would you work within a site like Kent and Canterbury Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Upper Hardres off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Will you stick to the specified products?
The specification decides the product. Specifications often reference BS EN 15651 or BS 6213.
How do you work with the site programme?
We work to your programme. Share the release dates and we will match our work to them.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you seal external joints in wet or cold weather?
External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work.
