Mastic sealing in Sheet Hill
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. If you’re dealing with the same joint failures repeated across a portfolio and brittle perimeter mastic across a building, we can put it right, on window and door perimeters on blocks, balcony and threshold joints and communal kitchens and washrooms alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Sheet Hill is the same: the right product in a properly prepared joint.
In and around smaller places like Sheet Hill, 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.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

For a school such as Plaxtol Primary School, perimeter mastic on windows and doors is a holiday job. For agents with blocks near Borough Green & Wrotham station, 1.7 miles to the north of Sheet Hill, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Common problems we fix in Sheet Hill
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
These are often picked up first by site or facilities staff:
- Complaints coming in block by block
- Worn sealant at communal door frames
- Water getting in round frames after rain
- Cracked, hardened mastic round windows on a block
If you are responsible for a building such as Plaxtol Church, frame and door mastic needs the same attention as any other property.

FAQs: Sheet Hill
Is Sheet Hill too small for you to travel to?
No. Places such as Sheet Hill are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you quote for a block close to Borough Green & Wrotham station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Can you plan resealing across several buildings?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the building height and any access already in place and we will confirm the approach in the quote.
Will residents or tenants be disturbed?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
How long does a typical visit take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Broken glass or failed sealed units
- Materials that need asbestos testing before work
- Substrate edges that need repairing first
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we will tell you honestly.
What we seal
- Balcony and threshold joints
- External wall and movement joints
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Shopfronts below residential blocks
- Communal entrances and stairwells
Leave it or put it right?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Converted and older buildings near places like Sheet Hill tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
There’s no price list, since every building and every scope is different. Call for a quote.

General trades versus a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
