Common problems we fix in Paddington Green
Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.
What tends to prompt an enquiry:
- Cold air coming in at window perimeters
- Patch repairs that keep failing
- Hard, chalky sealant that no longer flexes
- Perimeter sealant that has split or peeled away
Further education sites such as City of Westminster College (0.9 miles north-west of Paddington Green) are extended and refurbished from time to time, with mastic often programmed into the summer break.
Before you book anyone
- Do they follow the manufacturer’s priming guidance?
- What level of public liability insurance do they hold?
- How the existing material will be dealt with
- Can the work be phased to keep areas open?
About our facade sealing in Paddington Green
Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. If you are dealing with facade joints cracked through the middle and gaps between rainscreen or cladding panels, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Paddington Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Paddington Green, 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.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Building and refurbishing in Paddington Green
Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Paddington Green. Deliveries are booked and storage is tight, so mastic materials come in as needed. The area within 2 miles of Paddington Green holds plenty of hotels. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
Extensions at sites like St Mary's Hospital (to the south of Paddington Green) usually sit beside working departments, and the mastic follows strict access rules. Units on estates such as Brompton Cross District Shopping Centre., 1.8 miles south of Paddington Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

What else we do in Paddington Green
Building owners, agents and FMs in Paddington Green
We work for building owners and managing agents on everything from one building to a spread of sites around Paddington Green. Several sites can go on one quote, which keeps the paperwork simple.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Brief window cleaners about newly sealed joints
- Add perimeter sealant to planned maintenance checks
- Confirm the survey covers external sealants in older buildings
- Keep sills, gutters and drainage paths clear
Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.
Questions about Paddington Green
Is Brompton Cross District Shopping Centre., near Paddington Green, within your area?
Yes. Estates, retail parks and business parks around Paddington Green, Brompton Cross District Shopping Centre. Among them, are all within reach. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Could you schedule work at a campus like Imperial College London for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Do we need an asbestos check before resealing?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, and we’ll ask to see it. If asbestos is suspected, work stops until it is tested.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
How many days will you need on site?
That varies with the scale of the job, though a typical visit typically 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 will give you a timescale with the quote.
What we can’t put right
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Render or concrete edges that have broken away
- Work on the window or framing system itself
- Joints whose design needs changing by the specifier
If you are not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
Surfaces we seal
- Cladding panel joints
- Stone and brick facade joints
- Shopfront frames
- Window and door perimeters
- Coping and flashing joints
- Perimeter joints where frames meet the structure
Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Before we start on site
- Send your site hours and access windows
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints
