How we handle facade sealing in Upper Walthamstow
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have old perimeter mastic that has dried out and staining on stone next to old sealant, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Upper Walthamstow it comes down to the same thing: the right product in a properly prepared joint.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Upper Walthamstow: questions and answers
Can you take on a job at a hospital such as Whipps Cross University Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Do you offer coloured sealant?
It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Diagnose, treat, sign off
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Planning a London job such as one in Upper Walthamstow starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. 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.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Flag any permit to work we will need
- Tell staff and tenants when we’ll be in

Aftercare for building managers
For the best life from the joints:
- Insist on a full cut-out when joints are renewed
- Keep sills, gutters and drainage paths clear
- Inspect facade joints on a regular cycle
- Report water ingress at frames as soon as it shows
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading.
Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Joints whose design needs changing by the specifier
- Work on the window or framing system itself
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think.
What we seal
- Shopfront frames
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Window and door perimeters
- Coping and flashing joints
- Stone and brick facade joints
Why deal with it now?
Topping up a failed joint usually buys very little time. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

The ULEZ covers the whole of Greater London, Upper Walthamstow included, so site vehicles need to meet its standards or pay the daily charge. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Extensions at sites like Whipps Cross University Hospital, 0.7 miles to the south of Upper Walthamstow, usually sit beside working departments, and the mastic follows strict access rules.

Hotel extensions and refits, at places such as The Woodford Hotel, 0.8 miles to the north-east of Upper Walthamstow, typically run between busy periods, so the sealing is squeezed into short windows.
