How we handle facade sealing in Wennington
External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, so frosty or damp mornings can hold work back. We build that into the programme and tell you if the forecast changes the plan. If you have water coming in around window frames and hard, chalky sealant that no longer flexes, we can put it right, on cladding panel joints, perimeter joints where frames meet the structure and coping and flashing joints alike. Most enquiries from Wennington 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.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Wennington must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
The 12-month guarantee is for workmanship rather than 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.

How the job changes by surface
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. All of Greater London is in the ULEZ, and kerbside space in Wennington can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Let building users know which areas are affected
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Replacing glass or failed glazing units
- Arranging specialist high-level access, which is planned with the client
- Joints too narrow for the movement they take, which need redesign
If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think before you book.
Surfaces we seal
- Coping and flashing joints
- Stone and brick facade joints
- Shopfront frames
- Window and door perimeters
- Perimeter joints where frames meet the structure
- Cladding panel joints
Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Brief window cleaners about newly sealed joints
- Don’t wait for a second leak before calling
- Never let anyone seal over old sealant
- Share access with other external trades
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.
Facade sealing in Wennington: the local picture
Wennington has several hotels close by, all within 2 miles. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. As part of Greater London, Wennington 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.
For contractors at a college like New City College, which lies north-west of Wennington, perimeters and internal sealant are timed for the holidays. Hotel extensions and refits, at places such as The Manor Hotel & Restaurant, 1.5 miles north of Wennington, typically run between busy periods, so the sealing is squeezed into short windows. Recladding or extending a unit at a site like Purfleet Industrial Park (0.8 miles south-east of Wennington) brings panel joints and frame perimeters into the programme.
Wennington is about 4 miles south of Hornchurch, in Greater London. Across the RM13 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Common questions from Wennington clients
Will you plan work around the academic year at somewhere like New City College?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
What do you charge?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
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.
Cost factors for facade joints
Before we quote, we look at:
- Working within restricted access windows
- Induction, permit and paperwork requirements
- Which sealant the job calls for
- Quantities, in metres or numbers
Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
What to include in your enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Any specification or named product
- The asbestos register, for older buildings
- Any dates the work must fit around
- Drawings or a marked-up plan, if available
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email a schedule or drawings with what you know.
