Advice
Mastic sealing in Owlsmoor, done properly
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. We work on communal kitchens and washrooms, shopfronts below residential blocks and communal entrances and stairwells, and the usual reasons a site gets in touch are water getting in round frames after rain and no planned programme for sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Owlsmoor, preparation and product choice get the time they need.
Older buildings and conversions around places like Owlsmoor mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Signs you need mastic sealing in Owlsmoor
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified it comes away from one face.
It’s worth sending us details if you spot any of the following:
- The same joint failures repeated across a portfolio
- Failed external movement joints
- Brittle perimeter mastic across a building
- Damp patches beside frames
If you’re responsible for a building such as St George's Church, frame and door mastic needs the same attention as any other property.
What your quote should include
- Who will actually carry out the work
- Their public liability cover
- Whether old or failed sealant will be cut out, not overlaid
- The named product and why it was chosen
Questions about Owlsmoor
Is Wellington Business Park, near Owlsmoor, within your area?
Yes. We cover Owlsmoor and the area around it, including industrial estates, business parks and retail parks such as Wellington Business Park. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.
Can you quote for a block close to Sandhurst 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’ll quote and plan to suit.
Do you do block-wide mastic programmes?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
When is resealing likely to be due?
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.
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Keep a record of when each building was resealed
- Share the asbestos register when you send details
- Plan resealing building by building rather than complaint by complaint
- Prioritise elevations facing the weather
Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.

Mastic sealing in Owlsmoor: the local picture
Owlsmoor sits in one of the drier corners of the country, the South East.

Within reach of London, blocks run by agents and associations are common around stations.
For owners of several units at places like Wellington Business Park, 1.5 miles to the west of Owlsmoor, one programme can deal with frame and external mastic across the lot. If your remit includes a building such as Owlsmoor Primary School, frame and door mastic can be programmed for the holidays.

Why act early in Owlsmoor
Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure and less choice about when. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
