FAQs: Riddlesdown
Can you work around term dates at a campus such as Purley Language College?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is colour matching possible?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
How long does a job like this take?
That varies with the scale of the job, but the work normally takes whatever the programme allows, since the work follows the trades as areas are released. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
Construction mastic for commercial buildings in Riddlesdown
Since 2005 we have worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. For construction mastic on a scheme in Riddlesdown, send drawings through our quote form, or phone or email us to talk it through. If you are dealing with oversized or tapered gaps around new frames and mastic snags holding up handover, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Riddlesdown, preparation and product choice get the time they need.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Riddlesdown must meet its standards or pay the daily charge. Alongside that, sites normally need booked deliveries and a plan for where materials go.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

What the job involves on each surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room.
External facade and movement joints
Many facade substrates need a primer before sealing. We prime where the manufacturer specifies.
From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. 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.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.

Advice
Why act early in Riddlesdown
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. We can run snagging as its own phase before handover. Getting scaffold, permits or access booked in Riddlesdown takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Mastic packages on Riddlesdown sites
There are a number of hotels within about 2 miles of Riddlesdown. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Riddlesdown. Deliveries are booked and storage is tight, so mastic materials come in as needed.
For contractors at a college like Purley Language College, 1.1 miles to the west of Riddlesdown, perimeters and internal sealant are timed for the holidays. For a contractor working at a hospital such as Purley War Memorial Hospital (1 mile north-west of Riddlesdown), perimeter and facade sealing is planned around patients and deliveries. Units on estates such as Capital Business Centre, 1.5 miles to the north of Riddlesdown, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Site requirements such as inductions and permits
- Which sealant the job calls for
- Whether the work must be split into stages
- How much existing material needs removing
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- A wide shot and a close-up of the area
- Access details, including height
- The site address and postcode
- What the building is and how it’s used
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos to discuss it first.
When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Frames fitted out of tolerance
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer.
