About our facade sealing in Marylebone
Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on perimeter joints where frames meet the structure, window and door perimeters and shopfront frames, and the usual reasons a site gets in touch are old perimeter mastic that has dried out and facade joints cracked through the middle. Looking for mastic applicators who cover Marylebone? We have been sealing commercial buildings since 2005.
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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Questions about Marylebone
Does your area include sites such as Brompton Cross District Shopping Centre., near Marylebone?
Yes. We cover Marylebone and the area around it, including industrial estates, business parks and retail parks such as Brompton Cross District Shopping Centre.. Photos and a short description are enough for a first look.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How much does the work cost?
We don’t publish prices, as every site differs. Send photos or drawings and we will price it at a fixed figure.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Building owners, agents and FMs in Marylebone
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Building owners and managing agents use us on everything from one building to a spread of sites around Marylebone. Several sites can go on one quote, which keeps the paperwork simple.
Common problems we fix in Marylebone
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Look out for the following:
- Water coming in around window frames
- Weathered joints at frame-to-structure perimeters
- Gaps between rainscreen or cladding panels
- Patch repairs that keep failing
University estates such as University of Westminster, under half a mile north-east of Marylebone, 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 they’ll work around occupants
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a job in Marylebone, access comes first. 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.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close
- Share your working hours and any access restrictions

Surface by surface
Perimeter joints at frames and structure
Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint, not the framing or glazing itself.
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.
When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Maintenance after handover
Regular inspection catches problems early. In particular:
- Report water ingress at frames as soon as it shows
- Walk the elevations once or twice a year
- Plan facade sealing alongside redecoration
- Confirm the survey covers external sealants in older buildings
Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed instead of soaking the joints.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading behind the facade.

Marylebone has plenty of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
