Mastic sealing in Alverstone
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you are dealing with old repairs sealed over failed mastic and draughts at frames across a block, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Alverstone, that means joint design, primers and backing rod as standard.
Owners and agents with buildings around smaller places such as Alverstone tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Maintenance after handover
To get the most from the new sealant:
- Plan resealing building by building rather than complaint by complaint
- List the paperwork your organisation requires when you send details
- Include mastic in your cyclical inspections
- Have the asbestos survey to hand for older buildings
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.
Surface by surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
Window and door perimeters on blocks
We usually work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
Common questions from Alverstone clients
Does the sea air around Alverstone change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
Is Alverstone off your patch?
No. Places such as Alverstone are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Do you do block-wide mastic programmes?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Misted or failed double-glazed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Water coming in from the roof or rainwater goods
If in doubt, call 01277 525 020 or send photos by email and we will say what we think.

What else we do in Alverstone
Block-wide mastic in Alverstone
With the shore within about 2 miles, Alverstone counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you look after a block within reach of Sandown station, 1.1 miles to the south-east of Alverstone, frame and balcony mastic can be renewed on one programme. With historic buildings such as Haseley Manor (1.8 miles west of Alverstone) in the wider area, owners of older properties around Alverstone should expect mastic to need a product that suits old masonry. For a school such as Newchurch Primary School, perimeter mastic on windows and doors is a holiday job.
