Your questions answered
Will you take on work at estates like Chadha Industrial Estate, close to Hanwell?
Yes. Estates, retail parks and business parks around Hanwell, Chadha Industrial Estate among them, are all within reach. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Can you work around term dates at a campus such as University of West London?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
Can staff carry on working while you’re here?
Normally, yes. We phase the work so most of the building stays in use.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Facade sealing in Hanwell
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. If you have failed seals around shopfront and entrance frames and perimeter sealant that has split or peeled away, we can put it right, on shopfront frames, coping and flashing joints and cladding panel joints alike. Searching for sealant specialists in Hanwell? We’ve been sealing commercial buildings since 2005.
Construction in a London area such as Hanwell means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to bring in a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

- Access and working height

Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Facades, frames and programmes in Hanwell
As part of Greater London, Hanwell is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed. The area within 2 miles of Hanwell holds a good number of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
When a college such as Ealing and West London College (1.3 miles east of Hanwell) builds or refurbishes, the mastic package normally has to fit around students and staff. On a campus such as University of West London (1.2 miles east of Hanwell), new teaching buildings and residences are normally built and refurbished around the academic year. Units on estates such as Chadha Industrial Estate (0.6 miles south of Hanwell) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

From enquiry to sign-off
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 longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Send any specification or drawings in advance
- Agree which areas must stay open
- Tell us your opening times and when work is allowed

What the job involves on each surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building, so preparation and product choice matter.
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.
Looking after the joints
A few simple habits keep the new joints working:
- Clear debris that holds water against joints
- Ask about asbestos in pre-2000 mastic
- Don’t wait for a second leak before calling
- Add perimeter sealant to planned maintenance checks
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.
Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
