Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
What the job involves on each surface
Commercial and mixed-use buildings
Where retail and residential share a building, so phasing has to suit both. We plan around the site hours and access windows you give us.
Planned maintenance
Resealing can be scheduled alongside other planned works on a timetable you set.
Mastic sealing in Benhilton, done properly
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. If you are dealing with no planned programme for sealant and cracked, hardened mastic round windows on a block, we can put it right. For commercial sealant work in Benhilton, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. Work is planned with the agent so residents get notice and access is arranged in advance.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What else we do in Benhilton
Why deal with it now?
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Failed window or door frames, which need a window contractor
- Broken glass or failed sealed units
- Masonry that has broken away beside the joint
If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer.
Surfaces we seal

From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and we clear our waste as we work. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We inspect each building and record the joints that have failed.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Preparing the site
- Point out any areas we must not close
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space
Quotes
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.
Advice
Questions we’re asked in Benhilton
We manage a building near Sutton Common station. Can you help?
Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Can you work at a site such as Kimpton Industrial Park, by Benhilton?
Yes. Our area takes in Benhilton and its surroundings, with estates and business parks such as Kimpton Industrial Park included. A few photos and the unit address let us price the work.
How long before the joints can be used?
The product and site conditions decide that. 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, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned, and we’ll tell you how we’d approach it.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

We plan the time on site around your programme and access. You will have an expected duration with the quote.
