Mastic sealing in Acton Green
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. Site teams most often ask us about repeated reactive repairs to the same buildings and old repairs sealed over failed mastic, across communal entrances and stairwells, external wall and movement joints and window and door perimeters on blocks. Looking for mastic applicators who cover Acton Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Across Greater London, Acton Green included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.
A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or send details through our quote form and we’ll come back to it.

Leave it or put it right?
Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Quoting for work in Acton Green
We price every job individually. The things that drive the figure:
- Travel to remote or island sites
- The size and state of each joint
- Whether the work must be split into stages
- How much existing material needs removing
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Sending details for a quote
A few photographs plus some basic facts will normally do. Please tell us:
- Approximate linear metres or a joint schedule
- Access details, including height
- A wide shot and a close-up of the area
- The site address and postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Asbestos-containing sealant, which we don’t remove
- Misted or failed double-glazed units
- Substrate edges that need repairing first
If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.
Surfaces we seal
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Balcony and threshold joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- External wall and movement joints
Looking after buildings in and around Acton Green
Blocks in London are normally run by managing agents, landlords or housing associations, with residents to notify and access to arrange. We plan around the notices and access you arrange.
Blocks of flats and mixed-use buildings often cluster around stations such as South Acton station (under half a mile west of Acton Green) and their window and balcony mastic tends to age at the same rate across a building. For a school such as Ark Priory Primary Academy, perimeter mastic on windows and doors is a holiday job. If you manage student housing near a university such as Richmond American University London, 0.6 miles to the south-west of Acton Green, the summer turnaround is the time for mastic.

How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. All of Greater London is in the ULEZ, and kerbside space in Acton Green can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Share your working hours and any access restrictions
- Point out parking and an unloading spot
- Tell staff and tenants when we’ll be in
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Common questions from Acton Green clients
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Do you work for managing agents with blocks near South Acton station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
How long does a typical visit take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.

What else we do in Acton Green
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
