Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Avoid harsh cleaners on facade sealant
- Insist on a full cut-out when joints are renewed
- Check that rainwater leaves the facade the way it was designed to
- Record the product and colour used on each elevation
Keep a note of which product went in and when. Future work can then match the product and colour.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.
How we handle facade sealing in Brunswick Park
Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. The enquiries we see most involve leaks at window and door perimeters and previous reseals run over old sealant, on stone and brick facade joints, window and door perimeters and coping and flashing joints. Facilities teams, main contractors and managing agents in Brunswick Park tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. 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.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Why act early in Brunswick Park
The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Distance, for remote addresses
- The total length or number of joints
- Any access equipment needed
- Which sealant the job calls for
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
A few photos plus some basic facts will normally do. Please tell us:
- Whether an asbestos survey exists
- Approximate linear metres or a joint schedule
- The type of building and who uses it
- Specification clauses that apply
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
How a job runs
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Brunswick Park can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- 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.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
Before we start on site
- Point out parking and an unloading spot
- Share your working hours and any access restrictions
- Tell us what induction or permit system the site runs

Advice
Common problems we fix in Brunswick Park
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building, then it splits or peels.
Clients typically get in touch after noticing one or more of the following:
- Old perimeter mastic that has dried out
- Weathered joints at frame-to-structure perimeters
- Cladding panel joints that have opened up
- Unsightly perimeter sealant on a visible elevation
For contractors refurbishing units at places like North London Business Park, less than half a mile west of Brunswick Park, the mastic covers cladding panels, roller-door and window perimeters.
What to look for in a quote
- Are they CHAS accredited or on Constructionline?
- Do they follow the manufacturer’s priming guidance?
- Their plan for phasing and protecting the area
- What the guarantee covers, and for how long
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.
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and we will mention any edges that need repair.

Your questions answered
Can you work on a hospital site such as Priory 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.
Can you work at a site such as North London Business Park, by Brunswick Park?
Yes. We cover Brunswick Park and the area around it, including industrial estates, business parks and retail parks such as North London Business Park. A few photos and the unit address let us price the work.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
What type of sealant goes on window perimeters?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.
Do you run new sealant over the existing bead?
No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Building and refurbishing in Brunswick Park
The area within 2 miles of Brunswick Park holds plenty of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. The ULEZ covers the whole of Greater London, Brunswick Park 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.
On a healthcare site such as Priory Hospital (1.3 miles east of Brunswick Park), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. When a college such as Oak Hill College, 1 mile to the north of Brunswick Park, builds or refurbishes, the mastic package typically has to fit around students and staff.
