Mastic sealing in Pitshanger
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 and backing rod used wherever a joint is deep. If you are dealing with worn sealant at communal door frames and draught complaints from residents or tenants, we can put it right, whatever the surface. A single leaking joint is often how a building in Pitshanger first comes to us: we look at the rest while we’re there and tell you what we find.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000
- Tell us what induction or permit system the site runs
Getting a fixed quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email a schedule or drawings.

Quoting for work in Pitshanger
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Working within restricted access windows
- Site requirements such as inductions and permits
- Quantities, in metres or numbers
- The size and state of each joint
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
Good information means a firmer quote. When you get in touch, include:
- The asbestos register, for older buildings
- Clear photographs of the problem areas
- Anything awkward about access or site hours
- Specification clauses that apply
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email the details over with what you know.
When to call us in Pitshanger

- Cracked, hardened mastic round windows on a block
- A mix of products and colours from past repairs
- Open joints in brickwork or panels
- Damp patches beside frames

Planned mastic for Pitshanger portfolios
Blocks in London are normally run by managing agents, landlords or housing associations, with residents to notify and access to arrange. Our programme follows the access you agree with residents. There are two care or nursing homes within about 2 miles of Pitshanger. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.
Student blocks close to universities like University of West London (1 mile south of Pitshanger) are easiest to work on between tenancies. For a school such as North Ealing Primary School, perimeter mastic on windows and doors is a holiday job.

Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
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.
What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Misted or failed double-glazed units
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
Joints and surfaces we work on
- Communal entrances and stairwells
- Communal kitchens and washrooms
- External wall and movement joints
- Balcony and threshold joints
- Window and door perimeters on blocks
- Shopfronts below residential blocks
Questions about Pitshanger
Can work in a care setting near Pitshanger go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
How much does the work cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
Is it fine to apply new sealant on top of old?
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.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
