Your questions answered
Can you work at a site such as Capital Business Centre, by Selsdon?
Yes, sites like Capital Business Centre are within our area, along with the rest of Selsdon. A few photos and the unit address let us price the work.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
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, because fresh silicone will not bond with aged silicone.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them, and we work to what is specified.
About our facade sealing in Selsdon
A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. The enquiries we see most involve weathered joints at frame-to-structure perimeters and air leaks through failed facade joints, on window and door perimeters, perimeter joints where frames meet the structure and cladding panel joints. Most enquiries from Selsdon start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Construction in a London area such as Selsdon means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Maintenance after handover
To get the most from the new sealant:
- Clear debris that holds water against joints
- Avoid patch repairs on failed facade joints
- Keep the sealant details on the building file
- Investigate damp beside windows promptly
Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal across the elevation.
Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and cuts time on site.

What else we do in Selsdon
Doing it in-house
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Our process
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. In Selsdon, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We start with photos, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
What we need from you
- Tell staff and tenants when we’ll be in
- Tell us which areas need to stay in use
- Clear stock, furniture or equipment away from the joints

Advice
Facade sealing in Selsdon: the local picture
There are several hotels within about 2 miles of Selsdon. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Site traffic in Selsdon falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
For a contractor at a hotel such as Selsdon Park Hotel, 0.6 miles to the south-west of Selsdon, the mastic often has to be finished before a reopening date. Projects at colleges like John Ruskin College (to the north-east of Selsdon) tend to run to term dates, so the mastic is planned tightly. Recladding or extending a unit at a site like Capital Business Centre, 1.8 miles west of Selsdon, brings panel joints and frame perimeters into the programme.

What happens if it’s left?
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts. Getting scaffold, permits or access booked in Selsdon takes effort, so it makes sense to deal with every failing joint while access is in place.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Cracked or spalling substrates that need repair before sealing
- Work on the window or framing system itself

What sets the cost
Quotes vary with the job. It mainly depends on:
- Whether the work must be split into stages
- The product specified
- Quantities, in metres or numbers
- The size and state of each joint
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
What we need to price the job
There’s no need for a formal survey. These details are enough to start:
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
- The product your specification calls for
- How the joints are reached, and at what height
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
