Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Mastic sealing for commercial buildings in North Aston
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you have draughts at frames across a block and brittle perimeter mastic across a building, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in North Aston it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Rural conversions near places like North Aston often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.
A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or email drawings and photos and we’ll come back to it.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Glazing that needs replacing
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly.
Surfaces we seal
- External wall and movement joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Balcony and threshold joints
- Window and door perimeters on blocks
- Shopfronts below residential blocks
Signs you need mastic sealing in North Aston
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.
Any of the following is a good reason to get the joints checked over:
- A mix of products and colours from past repairs
- Draught complaints from residents or tenants
- Complaints coming in block by block
- Brittle perimeter mastic across a building
If you’re responsible for a building such as Church of St Mary, frame and door mastic needs the same attention as any other property.

How a job runs
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. Rural sites near North Aston may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We inspect the joints, building by building, and record what has failed and why.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Point out any areas we must not close

Advice
Questions about North Aston
Is North Aston too small for you to travel to?
No. Places such as North Aston 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.
Does your area include sites such as Hatch End Old Industrial Estate, near North Aston?
Yes. Estates, retail parks and business parks around North Aston, Hatch End Old Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.
What do you charge?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
How do you reach windows on upper floors?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Track which buildings were done and when
- Protect low-level joints in entrances
- Group repairs into a planned programme
- Share your contractor requirements early
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.
What the job involves on each surface
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
Blocks and managed buildings in North Aston
North Aston is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.

Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.
