Our process
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. All of Greater London is in the ULEZ, and kerbside space in Herne Hill can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Preparing the site
- Have the specification and drawings to hand
- Tell staff and tenants when we will be in
- Share the asbestos register for older buildings

Advice
How we handle facade sealing in Herne Hill
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around Herne Hill. Where sealant is the specified fix, we also take on coping and flashing joints. If you’re dealing with cold air coming in at window perimeters and patch repairs that keep failing, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Herne Hill, that means joint design, primers and backing rod as standard.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Herne Hill must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
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.

Facade sealing around Herne Hill: what changes locally
As part of Greater London, Herne Hill is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. There are plenty of hotels within about 2 miles of Herne Hill. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Building work at universities like King's College London, 1 mile north of Herne Hill, is often timed for the summer, mastic included. Units on estates such as Bessemer Park Industrial Estate (0.5 miles north-west of Herne Hill) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Work at a hotel such as London Hotel, 1 mile north-west of Herne Hill, tends to be programmed around bookings, mastic included.
Herne Hill is about 3 miles south of London, in Greater London. If you’re looking for facade sealing in Herne Hill, we can help, as we do across Greater London. Across Greater London, 764 places are covered, Herne Hill among them.

Herne Hill: questions and answers
Will you plan work around the academic year at somewhere like King's College London?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Would you work within a site like King's College Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work in cold or wet weather?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start, so we plan around the forecast.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you install glazing systems?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Different surfaces, different methods
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.
Window and door perimeters
Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus neutral-cure product, chosen for the frame and wall, goes in finished to throw water off the joint.
When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Working within restricted access windows
- Whether old sealant has to be cut out first
- How much there is to seal
- The size and state of each joint
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Sending details for a quote
To price the job accurately, we need a clear picture of the site. Useful things to include:
- The site address and postcode
- Rough lengths or quantities, or drawings if you have them
- How the joints are reached, and at what height
- Any specification or named product
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call the office on 01277 525 020 or send details through our quote form with what you know.
When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Cracked or spalling substrates that need repair before sealing
- Specialist high-level access methods
- Replacing glass or failed glazing units
If you’re not sure, just give us a call on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
