How we handle mastic sealing in Bonchurch
Across Bonchurch and the rest of the Isle of Wight, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. If you have communal area joints that look neglected and estate-wide sealant that is simply worn out, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Bonchurch, preparation and product choice get the time they need.
In and around smaller places like Bonchurch, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Block-wide mastic in Bonchurch
The sea is no more than about 1 mile from Bonchurch. On buildings near the shore, the side facing the weather usually needs its mastic renewed first. Bonchurch sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
With historic buildings such as Rylstone Manor (1.8 miles north of Bonchurch) in the wider area, owners of older properties around Bonchurch should expect mastic to need a product that suits old masonry. If you look after a block within reach of Shanklin station, which lies north of Bonchurch, frame and balcony mastic can be renewed on one programme.
Bonchurch is about 2 miles south of Shanklin, in the Isle of Wight. Looking for mastic sealing in Bonchurch?

Signs you need mastic sealing in Bonchurch
Buildings move with temperature and moisture, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
It’s worth sending us details if you spot any of the following:
- Estate-wide sealant that is simply worn out
- A mix of products and colours from past repairs
- No planned programme for sealant
- Communal area joints that look neglected
Trustees of buildings like Old St. Boniface Church can bring frame and external mastic into a planned maintenance list.

From enquiry to sign-off

What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Masonry that has broken away beside the joint
- Misted or failed double-glazed units
- Materials that need asbestos testing before work
If in doubt, call the office on 01277 525 020 or use the quote form and we’ll say what we think.
Joints and surfaces we work on
- External wall and movement joints
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Balcony and threshold joints
When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Questions we are asked in Bonchurch
Do you work for managing agents with blocks near Shanklin station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Does a coastal location like Bonchurch affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
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.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Do you work for managing agents and housing associations?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.
Do you do block-wide mastic programmes?
Yes. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.
How the job changes by surface
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. We quote building by building and work through them in turn.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
After the work
Once the work is signed off, these steps help:
- Keep a record of when each building was resealed
- Ask residents or tenants to report leaks and draughts early
- Look at the sunniest and most exposed elevations first
- List the paperwork your organisation requires when you send details
If a joint we sealed fails within 12 months, tell us and we will look at it. After that, regular inspection keeps the programme on track.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.
