Mastic sealing in Kilburn
Across Kilburn and the rest of Greater London, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on communal entrances and stairwells, balcony and threshold joints and external wall and movement joints, and the failures we’re asked to look at most are no planned programme for sealant and leaks at window and door perimeters. One point of contact handles commercial sealant work in Kilburn from the first photos to the final walk-round, whether it’s one building or several.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building, which is why block-wide programmes make sense.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we are called out for in Kilburn
Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Regular cleaning wears them further.
Most enquiries start with something like this:
- Leaks at window and door perimeters
- Brittle perimeter mastic across a building
- Old repairs sealed over failed mastic
- Draughts at frames across a block
Property owners at sites such as The Quadrant Business Centre (to the north-west of Kilburn) can have mastic renewed between lettings.
What your quote should include
- Will RAMS and insurance details be available?
- What the guarantee covers, and for how long
- How they’ll work around occupants
- Their pre-qualification and accreditations
From enquiry to sign-off
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a job in Kilburn, access comes first. Give us the hours we can be on site and we’ll schedule to suit.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
What we need from you
- Make sure the joints can be reached
- Let us know about inductions and permits
- Point out any areas we must not close
Quotes
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email drawings and photos.
Advice
Common questions from Kilburn clients
Do you take on jobs in Kilburn where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Does your area include sites such as The Quadrant Business Centre, near Kilburn?
Yes, sites like The Quadrant Business Centre are within our area, along with the rest of Kilburn. A few photographs and the unit address let us price the work.
Can you plan resealing across several buildings?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
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 entrances stay in use.
What paperwork can you provide?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Asbestos-containing sealant, which we don’t remove
- Leaks through the frame itself rather than the perimeter
- Broken glass or failed sealed units
Not sure which it is? You can call 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Quoting for work in Kilburn
There’s no standard rate for sealant work, because every site is different. What we look at:
- How much existing material needs removing
- Any access equipment needed
- Site requirements such as inductions and permits
- The size and state of each joint
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.
What to include in your enquiry
However big the job, the same details help:
- A wide shot and a close-up of the area
- The postcode of the building
- Whether the building will be occupied during the work
- The asbestos register, for older buildings
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or email drawings and photos.
What the job involves on each surface
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above the programme has to suit everyone. We plan around the site hours and access windows you give us.
Estate-wide resealing programmes
A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.
