Mastic sealing in Holloway
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. We work on communal kitchens and washrooms, window and door perimeters on blocks and shopfronts below residential blocks, and what we’re called in for most is old repairs sealed over failed mastic and movement joints with sealant missing. Most enquiries from Holloway start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For managing agents in Holloway, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Questions about Holloway
Can you work at a site such as Hannover Industrial Estate, by Holloway?
Yes. Our area takes in Holloway and its surroundings, with estates and business parks such as Hannover Industrial Estate included. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Will you work in a care home in Holloway without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
How much does the work cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you work to architects’ specifications?
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.
How many days will you need on site?
It depends on the scope, though a typical visit usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we’ll set out a timescale with the quote.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Glazing that needs replacing
- Masonry that has broken away beside the joint
- Materials that need asbestos testing before work
If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

What else we do in Holloway
What we are called out for in Holloway
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Most enquiries start with something like this:
- Water getting in round frames after rain
- Damaged joints in communal entrances and corridors
- Occupiers reporting cold air round windows
- A mix of products and colours from past repairs
Schools and community buildings such as Grafton Primary School need frame and external mastic kept sound like any building.
Before you book anyone

- Whether their applicators hold CSCS cards
- Their pre-qualification and accreditations

Surface by surface
Tenement and older buildings
Natural stone can be marked by the wrong sealant, so we pick a grade that won’t mark it.
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Inspecting joints regularly keeps programmes on track.
Blocks and managed buildings in Holloway
There are three care or nursing homes within about 2 miles of Holloway. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We work to your notice and access plan.
If you manage student housing near a university such as American University in London, less than half a mile north-east of Holloway, the summer turnaround is the time for mastic. For owners of several units at places like Hannover Industrial Estate, 0.5 miles to the south of Holloway, one programme can deal with frame and external mastic across the lot.

What affects the price in Holloway
Your fixed quote is built from the real scope. It allows for:
- Distance, for remote addresses
- How much there is to seal
- The site’s rules and procedures
- Any access equipment needed
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- Any specification or named product
- Photos of the joints, close up and from further back
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email drawings and photos with what you know.
Looking after the joints
Once the work is signed off, these steps help:
- List the paperwork your organisation requires when you send details
- Log resealing dates block by block
- Ask residents or tenants to report leaks and draughts early
- Start inspections with the most exposed faces
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Let building users know which areas are affected
- Share the asbestos register for older buildings
