How we handle mastic sealing in Acton Vale
Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. We work on shopfronts below residential blocks, window and door perimeters on blocks and communal kitchens and washrooms, and the usual reasons a site gets in touch are old repairs sealed over failed mastic and occupiers reporting cold air round windows. For commercial sealant work in Acton Vale, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In a London area such as Acton Vale, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

How the quote is worked out
The price varies from site to site. Expect it to depend on:
- Access and working height
- Phasing around occupants
- Location, for remote and island sites
- Quantities, in metres or numbers
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

A good diagnosis starts with the right details. Tell us:
- A wide shot and a close-up of the area
- Whether the building will be occupied during the work

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Questions about Acton Vale
Do you work for managing agents with blocks near Acton Central station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we will confirm the approach in the quote.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in Acton Vale can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Preparing the site
- Flag any permit to work we will need
- Send asbestos survey details if the building is pre-2000
- Make sure the joints can be reached
