Construction mastic in Pitshanger, done properly
On a new build, the mastic package is one of the last trades through each area, so it lands at exactly the point the programme is tightest. Mastic Doctor takes on mastic packages for main contractors and developers on schemes in Pitshanger, following the trades through the building as rooms and elevations become ready. If you have sanitary sealant damaged by following trades and mastic snags holding up handover, we can help, 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 are there and tell you what we find.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Cost factors for mastic packages
The price varies from site to site. Expect it to depend on:
- Access and working height
- Backing rod, priming and other preparation
- Which sealant the job calls for
- How much there is to seal
A quote for mastic packages depends on how many there are, their condition and the access. Call for a quote.

- Access details, including height
- Drawings or a marked-up plan, if available
- Clear photographs of the problem areas
- The site address and postcode
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call 01277 525 020 or email drawings and photos with what you know.
Pitshanger: questions and answers
Will you plan work around the academic year at somewhere like University of West London?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Would you work within a site like Cygnet Hospital Ealing?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
What does a mastic package usually include?
Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. We price to the specification and drawings.
Do you work in Pitshanger?
Yes. We cover Pitshanger and the rest of Greater London. To discuss a job, call the office on 01277 525 020 or email drawings and photos.
Is the mastic package guaranteed?
Each package is signed off with a 12-month workmanship guarantee. Damage by others after we’ve finished isn’t covered.
What site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually 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 works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
When to call us in Pitshanger
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
Most enquiries start with something like this:
- Window and door perimeters that won’t pass inspection
- Snag items on joints that need redoing before handover
- Bath and shower joints scraped during the final clean
- Different trades sealing to different standards
For contractors at a college like Alexander Cromwell College, which lies north-east of Pitshanger, perimeters and internal sealant are timed for the holidays.
What your quote should include
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
- Their public liability cover
- Who will actually carry out the work
How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. 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.
- We price from the drawings, specification and programme you send.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
What we need from you
- Share your working hours and any access restrictions
- Agree which areas must stay open
- Send any specification or drawings in advance

What the job involves on each surface
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move, and we use a flexible sealant where there’s movement.
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies and work only when conditions suit.
