How the job changes by surface
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.
Perimeter joints at frames and structure
Perimeter joints at frames often show their age first. We cut them out, prepare both faces and reseal to the specification with a product suited to glazing perimeters.
Facade sealing for commercial buildings in Brent Park
We don’t install glazing systems or replace glass. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. Site teams most often ask us about water coming in around window frames and cladding panel joints that have opened up, across coping and flashing joints, perimeter joints where frames meet the structure and cladding panel joints. One point of contact handles commercial sealant work in Brent Park from the first photographs to the final walk-round, whether it’s one building or several.
Around Brent Park, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

When to call us in Brent Park
Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.
What tends to prompt an enquiry:
- Sealant pulling away from frames or panels
- Patch repairs that keep failing
- Air leaks through failed facade joints
- Hard, chalky sealant that no longer flexes
University estates such as Imperial College London (to the south-east of Brent Park) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
What to look for in a quote
- How the joint faces will be prepared and primed
- Whether their applicators hold CSCS cards
- Will RAMS and insurance details be available?
- Their approach to joint depth and backing
Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Report water ingress at frames as soon as it shows
- Walk the elevations once or twice a year
- Insist on a full cut-out when joints are renewed
- Record the product and colour used on each elevation
After heavy weather, check vulnerable elevations for signs of water inside. An early report usually means a small reseal rather than a bigger repair.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading inside the building.
Our process
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and the joint faces cleaned.
- Primer is applied where the maker specifies 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.
Preparing the site
- Send any specification or drawings in advance
- Tell us what induction or permit system the site runs
- Send your site hours and access windows

Related advice
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Replacing glass or failed glazing units
- Joints too narrow for the movement they take, which need redesign
- Providing access systems for the work
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think before you book.
Surfaces we seal

Brent Park: questions and answers
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. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Will you take on work at estates like North Circular Business Park, close to Brent Park?
Yes. Our area takes in Brent Park and its surroundings, with estates and business parks such as North Circular Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Do you replace failed glazing units?
No. A glazing contractor handles that. What we seal are the joints around frames and panels across the facade.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
Places near Brent Park

Facade sealing around Brent Park: points for this area
There are a good number of hotels within about 2 miles of Brent Park. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. The ULEZ covers the whole of Greater London, Brent Park included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
Hotels like Bridge Park Hotel, 0.7 miles to the south of Brent Park, rarely close for long, so refurbishment mastic is phased floor by floor. For contractors refurbishing units at places like North Circular Business Park (under half a mile east of Brent Park), the mastic covers cladding panels, roller-door and window perimeters.
