About our mastic sealing in East Cowes
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Resealed mastic joints in East Cowes carry our 12-month guarantee. If you have estate-wide sealant that is simply worn out and worn sealant at communal door frames, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in East Cowes it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a smaller place such as East Cowes, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Masonry that has broken away beside the joint
- Water coming in from the roof or rainwater goods
- Failed window or door frames, which need a window contractor
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.
Joints and surfaces we work on
- Window and door perimeters on blocks
- Balcony and threshold joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- External wall and movement joints
- Communal entrances and stairwells
What affects the price in East Cowes
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- The site’s rules and procedures
- Quantities, in metres or numbers
- The size and state of each joint
- How accessible the joints are
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- The site address and postcode
- Approximate linear metres or a joint schedule
- How the joints are reached, and at what height
- Any dates the work must fit around
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, ring 01277 525 020 or send photos by email.

East Cowes: questions and answers
Is Island Technology Park, near East Cowes, within your area?
Yes. Estates, retail parks and business parks around East Cowes, Island Technology Park among them, are all within reach. Photos and a short description are enough for a first look.
Is East Cowes too far out for you?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Related advice
Looking after the joints
After handover, these steps help:
- Prioritise elevations facing the weather
- Protect low-level joints in entrances
- Ask residents or tenants to report leaks and draughts early
- Plan resealing building by building rather than complaint by complaint
Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.
One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
