Facade sealing in Duckett's Green
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. We work on perimeter joints where frames meet the structure, window and door perimeters and stone and brick facade joints, and the usual reasons a site gets in touch are hard, chalky sealant that no longer flexes and draughts around frames and panels. Most enquiries from Duckett's Green start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Construction in a London area such as Duckett's Green means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What we’re called out for in Duckett's Green
Overlaying old sealant is a common shortcut that fails quickly. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
Things that usually lead to an enquiry:
- Failed sealant on precast panel joints
- Leaks at window and door perimeters
- Staining on stone next to old sealant
- Patch repairs that keep failing
Units on estates such as Crusader Industrial Park, 0.8 miles to the south of Duckett's Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Questions to ask before you book
- Will failed sealant be removed rather than covered?
- Will CSCS-carded applicators be on site?
- What site paperwork they can supply
- Whether primer will be used where the manufacturer specifies it

Diagnose, treat, sign off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. For a job in Duckett's Green, access comes first. Send the building rules and access times with your enquiry.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- 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.
What we need from you
- Let us know about inductions and permits
- Tell us your opening times and when work is allowed

Duckett's Green: questions and answers
Do you cover business parks and estates near Duckett's Green, such as Crusader Industrial Park?
Yes. We cover Duckett's Green and the area around it, including industrial estates, business parks and retail parks such as Crusader Industrial Park. Photos and a short description are enough for a first look.
Can you work on a hospital site such as St Ann's Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What type of sealant goes on window perimeters?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Can you quote from photographs?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Looking after the joints
After handover, these steps help:
- Keep pressure washers away from fresh sealant
- Insist on a full cut-out when joints are renewed
- Share access with other external trades
- Add perimeter sealant to planned maintenance checks
Following storms, look inside for damp or staining near frames. An early report normally means a small reseal rather than a bigger repair.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.
Building and refurbishing in Duckett's Green
As part of Greater London, Duckett's Green is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed. The area within 2 miles of Duckett's Green holds a good number of hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
Further education sites such as The College of Haringey, 1 mile east of Duckett's Green, are extended and refurbished from time to time, with mastic often programmed into the summer break. Hotels like Haringey Hotel, 0.8 miles south of Duckett's Green, rarely close for long, so refurbishment mastic is phased floor by floor.

Quoting for work in Duckett's Green
What shapes the price:
- The size and state of each joint
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
- The product specified
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.
Sending details for a quote
To price the job accurately, we need a clear picture of the site. Send us:
- Where the site is, with the postcode
- Whether an asbestos survey exists
- Any dates the work must fit around
- Drawings or a marked-up plan, if available
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Why it’s worth doing now in Duckett's Green
Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
