Commercial mastic work in Hanwell
Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us; phasing keeps some washrooms, kitchens or entrances available while others are done. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. If you have smeared sealant across finishes from a rushed job and layers of sealant, all of them failing, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hanwell is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In Hanwell, as anywhere, the first joints to go are typically the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.
Buildings in a London area such as Hanwell rarely close for maintenance: occupied offices, ground-floor retail under residential floors and busy shared entrances. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.
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.

After the work
A few simple habits keep the new joints working:
- Note dates and locations of sealant work for future planning
- Have extract fans checked so wet areas dry out
- Keep barriers up until the new sealant has cured
- Add sealant to the planned maintenance inspection list
Later works are the usual way new joints get damaged. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. If that happens, phone 01277 525 020 or send details through our quote form and we will price putting it right.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.
From enquiry to sign-off
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

How the job changes by surface
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t, in a shade that suits the frame.
Shop fronts and retail fit-outs
Retail work normally has to fit around trading. Tell us your trading hours and access windows and we’ll plan around them.
Common questions from Hanwell clients
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method.
Do you cover business parks and estates near Hanwell, such as Chadha Industrial Estate?
Yes. Our area takes in Hanwell and its surroundings, with estates and business parks such as Chadha Industrial Estate included. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
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 do we get a quote?
The main factors are metres of joint, removal, access, the product and how many phases there are. For a fixed quote, send details through our quote form.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you cover Hanwell?
Yes. Sites across Hanwell are covered.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Broken glass or blown double-glazed units
- Walls or slabs moving more than any sealant can take
- Suspect materials that need testing and specialist removal
If in doubt, phone 01277 525 020 or email us and we’ll say what we think before you book.
What we seal
- Movement joints in walls and floors
- Window and door perimeters
- Floor and threshold joints
- External facade joints
- Washrooms and tea points
- Kitchen worktops and splashbacks
What sets the cost
We price every job individually. The main factors are:
- Access and working height
- The product specified
- Distance, for remote addresses
- Joint width, depth and condition
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
Sending details for a quote
A few photographs plus some basic facts will normally do. Please tell us:
- The type of building and who uses it
- Asbestos survey details if the building is older
- A wide shot and a close-up of the area
- Where the site is, with the postcode

General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
