What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Deciding which fire-stopping product a penetration needs
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Oversized gaps that need packing or adjustment by others
If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Joints and surfaces we work on

Construction mastic in Gillette Corner, done properly
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, and we are fully insured. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. If you are dealing with failed sealant in an existing building being refurbished and inconsistent sealant finishes from plot to plot, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Gillette Corner is the same: the right product in a properly prepared joint.
Around Gillette Corner, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Cost factors for mastic packages
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Which sealant the job calls for
- Distance, for remote addresses
- Whether the work must be split into stages
- The size and state of each joint
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- Whether an asbestos survey exists
- What the building is and how it’s used
- When you need the work done
- Where the site is, with the postcode
Every quote starts with the facts: 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.
Your questions answered
Is West Cross Industrial Park, near Gillette Corner, within your area?
Yes. We cover Gillette Corner and the area around it, including industrial estates, business parks and retail parks such as West Cross Industrial Park. A few photos and the unit address let us price the work.
Could you schedule work at a campus like University of West London (Brentford Campus) for the vacation?
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.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Is colour matching possible?
It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Surface by surface
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product and hygienic or food-safe grades wherever food contact is possible.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly.

Our process
On arrival, 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 usually taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. Planning a London job such as one in Gillette Corner starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- 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.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site
- Tell us what induction or permit system the site runs
- Move anything stored against the joints
- Arrange parking or a loading space

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Building and refurbishing in Gillette Corner
Site traffic in Gillette Corner falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. A good number of hotels sit less than 2 miles from Gillette Corner. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
When a college such as West Thames College, 0.8 miles south-west of Gillette Corner, builds or refurbishes, the mastic package usually has to fit around students and staff. New wings at hospitals like West Middlesex Hospital, 0.8 miles to the south of Gillette Corner, bring long runs of window and panel joints to seal. New units and refits on sites such as West Cross Industrial Park (less than half a mile north-east of Gillette Corner) need their panel and perimeter joints sealed to the specification.
Gillette Corner is about 2 miles north-east of Hounslow, in Greater London. Any commercial site in Gillette Corner is covered. We work across 764 places in Greater London, from busy centres to rural villages. For work in that direction, see our London page.
We take on mastic packages across the TW7 and TW8 postcode area, whatever the building. If your site is on Wood Lane, Syon Lane and Darcy Road or close by, we can quote for mastic packages. We also cover Brentford End (1 mile east), Spring Grove (1 mile west), Isleworth (1 mile south), Osterley (1 mile west) and Brentford (1 mile east) for mastic packages. A short drive away, we cover London (10 miles east), City of Westminster (8 miles east), Marylebone (8 miles east), Kensington (6 miles east), St Pancras (9 miles east) and Shoreditch (11 miles east).
Around Gillette Corner
We work on buildings around The Green School, Coach and Horses pub and Boston Manor Park and the streets around them. There’s a railway station in Gillette Corner itself: Syon Lane station. Nearby you’ll also find West Middlesex University Hospital (0.7 miles south) and Musical Museum (1.5 miles east). Open spaces near Gillette Corner include Long Wood and Garden Lake.
Why deal with it now?
It helps to bring the mastic subcontractor in before the package is urgent. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification, which avoids last-minute problems. Called in at the end, the same issues surface during handover. In Gillette Corner, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Why us?
- Old sealant cut out, never sealed over
- Constructionline member for supplier checks
- CHAS accredited contractor
- A range of standard colours, depending on the product
