Mastic sealing in Connaught Village, done properly
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. We work on window and door perimeters on blocks, shopfronts below residential blocks and communal kitchens and washrooms, and what we’re called in for most is old repairs sealed over failed mastic and estate-wide sealant that is simply worn out. Whoever orders the work in Connaught Village, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. We work to the agent’s notice and access plan, so residents know what’s happening.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to bring in 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. A poor seal in places like these tends to cost more to put right later.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Your questions answered
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Will you take on a block within reach of London Paddington station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure.
Do you work in Connaught Village?
Yes. Connaught Village falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or email us.
Can you seal joints high up on a block?
Every block is different. We agree access with you at quote stage so there are no surprises.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.

When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Misted or failed double-glazed units
- Materials that need asbestos testing before work
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
What we seal
- Balcony and threshold joints
- Communal entrances and stairwells
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Window and door perimeters on blocks
Why it’s worth doing now in Connaught Village
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- How much there is to seal
- Any access equipment needed
- Backing rod, priming and other preparation
- Travel to remote or island sites
A quote for mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- Clear photos of the problem areas
- The product your specification calls for
- How the joints are reached, and at what height
- The postcode of the building
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Do you need mastic sealing in Connaught Village?
Buildings move with temperature and moisture, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
If one of these sounds familiar, it’s time for a closer look:
- Estate-wide sealant that is simply worn out
- Window mastic that has split and shrunk
- Patchy repairs in mismatched sealant
- Damp patches beside frames
Buildings close to stations like London Paddington station, 0.5 miles to the west of Connaught Village, are often flats over shops, with frame mastic to keep sound.
Before you book anyone
- Whether their applicators hold CSCS cards
- How the joint faces will be prepared and primed
- What level of public liability insurance do they hold?
- Is the sealant right for the movement and the substrate?
