About our mastic sealing in Ventnor
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on window and door perimeters on blocks, balcony and threshold joints and shopfronts below residential blocks, and the usual reasons a site gets in touch are old repairs sealed over failed mastic and damaged joints in communal entrances and corridors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Ventnor it comes down to the same thing: the right product in a properly prepared joint.
In a smaller place such as Ventnor, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common problems we fix in Ventnor
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
Common reasons buildings call us in:
- Draughts at frames across a block
- Brittle perimeter mastic across a building
- Complaints coming in block by block
- Patchy repairs in mismatched sealant
Historic properties like Rylstone Manor (to the north-east of Ventnor) show the age of some local stock, where frame mastic must suit soft brick or stone.
Questions to ask before you book
- How they’ll work around occupants
- Who will actually carry out the work
- How the joint faces will be prepared and primed
- Is the sealant right for the movement and the substrate?
When something else is needed
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Leaks from above rather than through a joint
- Failed window or door frames, which need a window contractor
- Materials that need asbestos testing before work
If you are not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer.

Owners, agents and contractors
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
FAQs: Ventnor
Does a coastal location like Ventnor affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Can you quote for a block close to Shanklin station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Can you seal joints high up on a block?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How many days will you need on site?
It depends on the scope, though a typical visit normally takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. What matters most for a job in Ventnor is a clear list of what needs doing. You’ll then get a fixed price for the work.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.

Block-wide mastic in Ventnor
The sea is no more than about 1 mile from Ventnor. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, so it’s worth inspecting those sides more often. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building typically need attention first.
Buildings close to stations like Shanklin station, 3 miles to the north-east of Ventnor, are often flats over shops, with frame mastic to keep sound. For owners of several units at places like Ventnor Industrial Estate, which lies north of Ventnor, one programme can deal with frame and external mastic across the lot.

What else we do in Ventnor
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
