About our facade sealing in Broadfields Estate
We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. Site teams most often ask us about weathered joints at frame-to-structure perimeters and hard, chalky sealant that no longer flexes, across perimeter joints where frames meet the structure, cladding panel joints and shopfront frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Broadfields Estate, that means joint design, primers and backing rod as standard.
Around Broadfields Estate, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Providing access systems for the work
- Joints whose design needs changing by the specifier
- Render or concrete edges that have broken away
If you are not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer.
Joints and surfaces we work on
- Window and door perimeters
- Stone and brick facade joints
- Cladding panel joints
- Coping and flashing joints
- Shopfront frames
- Perimeter joints where frames meet the structure
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Clear debris that holds water against joints
- Walk the elevations once or twice a year
- Keep pressure washers away from fresh sealant
- Combine resealing with other works that need access
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards with a compatible product.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in instead of after the damage.

Signs you need facade sealing in Broadfields Estate
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
Any of the following is a good reason to get the joints checked over:
- Perimeter joints where frames meet the structure
- Leaks at window and door perimeters
- Previous reseals run over old sealant
- Hard, chalky sealant that no longer flexes
New units and refits on sites such as Mill Yard Industrial Estate (1.6 miles south of Broadfields Estate) need their panel and perimeter joints sealed to the specification.

Sites and facades in and around Broadfields Estate
Site traffic in Broadfields Estate falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. The area within 2 miles of Broadfields Estate holds a number of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
On a campus such as Middlesex University, 2.5 miles south-east of Broadfields Estate, new teaching buildings and residences are typically built and refurbished around the academic year. Hotels like Railway Hotel, 1.1 miles to the south of Broadfields Estate, rarely close for long, so refurbishment mastic is phased floor by floor.

Broadfields Estate: questions and answers
Can you work on a hospital site such as Edgware Community Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Could you schedule work at a campus like Middlesex University for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Which sealant do you use on facades?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email the details over. Include photos or drawings if you have them.
Can you work on upper floors?
That comes down to the access arranged for the job. Share what access exists or is planned when you send details.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
Our process
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We start with photographs, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- 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.
- We go over the completed work with you before leaving.
Before we start on site
- Send any specification or drawings in advance
- Move anything stored against the joints
- Share your working hours and any access restrictions
