What the job involves on each surface
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and areas needing repair are flagged.
Precast concrete panels
Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.
Facade sealing for commercial buildings in Falconwood
Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. We work on window and door perimeters, cladding panel joints and coping and flashing joints, and the usual reasons a site gets in touch are air leaks through failed facade joints and hard, chalky sealant that no longer flexes. Whoever orders the work in Falconwood, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Sites and facades in and around Falconwood
A number of hotels sit less than 2 miles from Falconwood. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Falconwood. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
Extensions at sites like Memorial Hospital, 1.5 miles west of Falconwood, usually sit beside working departments, and the mastic follows strict access rules. New units and refits on sites such as Green Lane Business Park, 2.2 miles south-west of Falconwood, need their panel and perimeter joints sealed to the specification.

When to call us in Falconwood
Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.
Any of the following is a good reason to get the joints checked over:
- Weathered facade joints that have lost their grip
- Air leaks through failed facade joints
- New sealant peeling off old mastic
- Weathered joints at frame-to-structure perimeters
Further education sites such as Rose Bruford College, 1.5 miles to the south of Falconwood, are extended and refurbished from time to time, with mastic often programmed into the summer break.
What your quote should include
- Proof of insurance
- Will CSCS-carded applicators be on site?
- Is the sealant right for the movement and the substrate?
- Health and safety accreditation such as CHAS
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. In Falconwood, 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.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Before we start on site
- Tell staff and tenants when we will be in
- Arrange parking or a loading space
- For older buildings, check the asbestos register before work

What we can’t put right
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Providing access systems for the work
- Water getting in through cracked render or porous masonry
- Work on the window or framing system itself
If you’re not sure, just ring 01277 525 020 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Window and door perimeters
- Shopfront frames
- Stone and brick facade joints
- Cladding panel joints
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Common questions from Falconwood clients
Is hospital work, at somewhere like Memorial Hospital, something you do?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you plan work around the academic year at somewhere like University of Greenwich Avery Hill Campus?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
How many days will you need on site?
That varies with the scale of the job, but the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you look at water coming in around a frame?
Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Can you work in cold or wet weather?
Rain and frost can pause external sealing. The programme allows for it and we tell you if the forecast changes things throughout the job.
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.
Do you run new sealant over the existing bead?
No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
What happens if it’s left?
The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Failed sealant in a building in Falconwood can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.
