How we handle mastic sealing in Heathrow
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. If you’re dealing with old repairs sealed over failed mastic and no planned programme for sealant, we can help, whatever the surface. Searching for sealant specialists in Heathrow? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
For managing agents in Heathrow, resident access, notice periods and the building’s rules shape the job. Work is planned with the agent so residents get notice and access is arranged in advance.
Every job we finish is backed by a 12-month workmanship guarantee, in Heathrow as everywhere else we work. If our installation lets you down in that time, we return and fix it.

For owners and agents in Heathrow
Blocks in London are typically run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We fit the programme to your notice periods.
Student blocks close to universities like Brunel University of London, 4.6 miles to the north of Heathrow, are easiest to work on between tenancies. If your remit includes a building such as Bedfont Primary School, frame and door mastic can be programmed for the holidays. If you look after a block within reach of Heathrow Terminals 2 & 3 Rail station, under half a mile to the north of Heathrow, frame and balcony mastic can be renewed on one programme.
Heathrow is about 2 miles north-west of Feltham, in Greater London. We cover commercial sites throughout Heathrow, for single jobs and planned programmes alike. Heathrow is one of 764 places in Greater London on our list for mastic joints. Sites around London have their own page, about 16 miles away.
We take on mastic joints across the TW6 postcode area. We also cover West Bedfont (1 mile south-west), Hatton (1 mile east), Bedfont (1 mile south-east), Stanwell (1 mile south-west) and Harlington (1 mile north-east). Further afield, our area takes in City of Westminster (13 miles east), Marylebone (14 miles east), Kensington (11 miles east), St Pancras (15 miles east), Hampstead (13 miles north-east) and Ruislip (8 miles north).
Landmarks near Heathrow
Locally, jobs take us to sites close to The Queen's Arms and Space Studio West London and the streets around them. Heathrow has its own railway station: Heathrow Terminals 2 & 3 Rail station. Nearby you’ll also find Treaty Centre (3.8 miles east) and Harlington (1.6 miles north). The countryside around Heathrow includes Staines Reservoirs and Crane Meadows.
Common questions from Heathrow clients
Will you take on a block within reach of Heathrow Terminals 2 & 3 Rail station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Is Heathrow in your area?
Yes. Sites across Heathrow are covered, and the same phone number covers every area.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Do you supply RAMS and insurance details?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
What the job involves on each surface
Planned maintenance
Planned resealing replaces emergency callouts and keeps budgets predictable.
Communal areas
Low-level communal joints get damaged more than most and tend to fail first.
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal 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.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
What we need from you
- Let building users know which areas are affected
- Agree which areas must stay open
- Flag any permit to work we will need

Work for main contractors and building owners
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Reduce knocks to communal area joints
- Make mastic part of routine maintenance checks
- Keep a record of when each building was resealed
- Share your contractor requirements early
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.
