Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
About our mastic sealing in Oakwood
Across Oakwood and the rest of Greater London, we work the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. The enquiries we see most involve movement joints with sealant missing and brittle perimeter mastic across a building, on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Oakwood, that means joint design, primers and backing rod as standard.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For a block or estate, it helps to know where we can park and stage materials.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a few days for most blocks, with larger programmes scheduled building by building, and we clear our waste as we work. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we look at the mastic on each building and note what needs replacing.
- 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.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Tell us your opening times and when work is allowed
- Warn occupants and staff about the work
- Clear stock, furniture or equipment away from the joints

Why deal with it now?
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Signs you need mastic sealing in Oakwood
Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
Look out for the following:
- Mastic failing across several blocks on an estate
- A mix of products and colours from past repairs
- Worn sealant at communal door frames
- Cracked, hardened mastic round windows on a block
Historic properties like Forty Hall, 3.1 miles to the north-east of Oakwood, show the age of some local stock, where frame mastic must suit soft brick or stone.
What to look for in a quote
- The named product and why it was chosen
- Their approach to joint depth and backing
- What level of public liability insurance do they hold?
- Do they follow the manufacturer’s priming guidance?
Your questions answered
Can you work in a care home near Oakwood with residents in?
Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.
Do you cover business parks and estates near Oakwood, such as North London Business Park?
Yes. We cover Oakwood and the area around it, including industrial estates, business parks and retail parks such as North London Business Park. Photos and a short description are enough for a first look.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
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.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Is asbestos a concern with old mastic?
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.
Quoting for work in Oakwood
Each job is priced on its own details. The things that drive the figure:
- Induction, permit and paperwork requirements
- Joint width, depth and condition
- How accessible the joints are
- Whether old sealant has to be cut out first
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
However big the job, the same details help:
- The type of building and who uses it
- The product your specification calls for
- Approximate linear metres or a joint schedule
- How the joints are reached, and at what height

Different surfaces, different methods
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.
