About our mastic sealing in Well Street
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. Site teams most often ask us about communal area joints that look neglected and draught complaints from residents or tenants, on communal entrances and stairwells, balcony and threshold joints and communal kitchens and washrooms. Looking for mastic applicators who cover Well Street? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Around smaller places like Well Street, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Why deal with it now?
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Converted and older buildings near places like Well Street tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

How the quote is worked out
What shapes the price:
- How much there is to seal
- Backing rod, priming and other preparation
- Which sealant the job calls for
- Induction, permit and paperwork requirements
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What to include in your enquiry
However big the job, the same details help:
- When you need the work done
- Whether the building will be occupied during the work
- The asbestos register, for older buildings
- Anything awkward about access or site hours
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email the details over if you’d rather talk the job through.
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Some joints are best left to specialists: 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.

Mastic sealing around Well Street: what changes locally
Well Street sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

If you manage student housing near a university such as University for the Creative Arts - Maidstone, 3.2 miles east of Well Street, the summer turnaround is the time for mastic. Buildings close to stations like East Malling station (to the east of Well Street) are often flats over shops, with frame mastic to keep sound.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Keep a record of when each building was resealed
- Keep bins and bikes away from communal door frames
- Share the asbestos register when you send details
- Make mastic part of routine maintenance checks
If paintable sealant was used, decoration can follow once it has cured. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
What we’re called out for in Well Street
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
If one of these sounds familiar, it’s time for a closer look:
- Brittle perimeter mastic across a building
- Repeated reactive repairs to the same buildings
- Leaks at window and door perimeters
- Old repairs sealed over failed mastic
Site managers at schools like The Malling School can fit frame mastic into the summer works.

Common questions from Well Street clients
Do you work for managing agents with blocks near East Malling station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Is a smaller place like Well Street outside your area?
No. Places such as Well Street are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Can you take on resealing for a block portfolio?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
