Facade sealing for Riddlesdown sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Your questions answered
Can you work around term dates at a campus such as Purley Language College?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Do you run new sealant over the existing bead?
No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.
How much does the work cost?
Every job gets its own fixed quote. For yours, call 01277 525 020 or email us with a description of the work.
Can you look at water coming in around a frame?
Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we’ll tell you which.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Can one quote cover more than one building?
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 we handle facade sealing in Riddlesdown
Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. We work on stone and brick facade joints, shopfront frames and window and door perimeters, and what we are called in for most is sealant pulling away from frames or panels and air leaks through failed facade joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Riddlesdown, that means joint design, primers and backing rod as standard.
Around Riddlesdown, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What else we do in Riddlesdown
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- The product specified
- Quantities, in metres or numbers
- Location, for remote and island sites
- Removal of failed or old sealant
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Photos of the joints, close up and from further back
- How the joints are reached, and at what height
- Any specification or named product
- Approximate linear metres or a joint schedule
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or send details through our quote form.
Site staff or a sealant specialist?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Mastic packages on Riddlesdown sites
As part of Greater London, Riddlesdown is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around Riddlesdown takes in a number of hotels. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
When units on a site such as Capital Business Centre, 1.5 miles to the north of Riddlesdown, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. When a school such as Harris Primary Academy Kenley is extended or refurbished, the mastic package is often squeezed into the holidays.

How a job runs
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. In Riddlesdown, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
What we need from you
- Share your working hours and any access restrictions
- Confirm the product named in the specification
- Move anything stored against the joints

Advice
What the job involves on each surface
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch.
When something else is needed
We check first that sealant really is the fix. It isn’t the answer for:
- Joints whose design needs changing by the specifier
- Providing access systems for the work
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Where we work in Riddlesdown
- Window and door perimeters
- Stone and brick facade joints
- Shopfront frames
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Coping and flashing joints
What we’re called out for in Riddlesdown
When the sealant tears down its centre, it has typically been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Typical triggers for a call:
- Gaps between rainscreen or cladding panels
- Old perimeter mastic that has dried out
- Failed seals around shopfront and entrance frames
- Leaks at window and door perimeters
When a college such as Purley Language College (1.1 miles west of Riddlesdown) builds or refurbishes, the mastic package typically has to fit around students and staff.
