What the job involves on each surface
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer; we work to the specification and the manufacturer’s installation guidance.
Window and door perimeters
Internal perimeters are normally sealed with a paintable product where decorating follows. We follow what’s specified, and colour-matched products can be used where the frame is on show.
About our construction mastic in West Ealing
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. The enquiries we see most involve inconsistent sealant finishes from plot to plot and bath and shower joints scraped during the final clean, on internal decorators’ caulk, cladding and panel joints and window and door perimeters. Whether you call it commercial sealant work, mastic application or joint sealing, in West Ealing it comes down to the same thing: the right product in a properly prepared joint.
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, so tidy, well-planned work matters.
Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email the details over and we’ll come back to it.

Common problems we fix in West Ealing
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.
Most enquiries start with one or more of the following:
- A mastic package split between trades with no clear owner
- Mastic snags holding up handover
- Old sealant on a refurbishment that needs stripping before new work
- Frame gaps too wide for sealant alone
Units on estates such as Chadha Industrial Estate (0.6 miles south of West Ealing) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What your quote should include
- Their public liability cover
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
- Is the sealant right for the movement and the substrate?
Facades, frames and programmes in West Ealing

Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in West Ealing. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.

When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Frames fitted out of tolerance
- Joint design decisions that belong to the architect or engineer
- Damage to finishes by other trades after we’ve sealed

- Floor and skirting junctions
- Brick and block movement joints
- Window and door perimeters
On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes whatever the programme allows, since the work follows the trades as areas are released, and our waste is bagged and taken away as we go. In West Ealing, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Tell us which areas need to stay in use
- Share the asbestos register for older buildings
- Warn occupants and staff about the work

Advice
Questions about West Ealing
Can you work on a hospital site such as Ealing Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work around term dates at a campus such as University of West London?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you work plot by plot or floor by floor?
Working to your programme, we seal each area as it’s handed over. The sequence is settled with your site team and adjusted as things change.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What do you charge?
There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.
Maintenance after handover
To get the most from the new sealant:
- Check frame gaps are within the sealant’s range before sealing
- Keep finished joints away from paint, plaster and scrapers
- Record the products used in the O&M file
- Brief the final clean team to avoid blades near sealant
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known. Tell us what records you need and we’ll confirm with the quote.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
Doing it in-house
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.
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.
