Facade sealing in Cranford
A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. Site teams most often ask us about draughts around frames and panels and failed seals around shopfront and entrance frames, across perimeter joints where frames meet the structure, cladding panel joints and window and door perimeters. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Cranford it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Cranford, 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, so tidy, well-planned work matters.

Facade sealing around Cranford: points for this area
The ULEZ covers the whole of Greater London, Cranford included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. Plenty of hotels sit less than 2 miles from Cranford. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
New units and refits on sites such as Heathrow International Trading Estate (0.5 miles south of Cranford) need their panel and perimeter joints sealed to the specification. On a healthcare site such as Hounslow Hospital, 1.6 miles to the east of Cranford, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Work at a hotel such as Atrium Hotel Heathrow (to the south-west of Cranford) tends to be programmed around bookings, mastic included.

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. All of Greater London is in the ULEZ, and kerbside space in Cranford can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Before we start on site
- Point out any areas we must not close
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand

Your questions answered
Will you plan work around the academic year at somewhere like University of London?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you take on a job at a hospital such as Hounslow Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
What type of sealant goes on window perimeters?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.
Do you cover Cranford?
Yes. Sites across Cranford are covered, with one number for every area we cover.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Different surfaces, different methods
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.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather, so preparation and product choice matter.
When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Avoid patch repairs on failed facade joints
- Check the asbestos register before old mastic is disturbed
- Keep the sealant details on the building file
- 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. Ask the installer to reseal it properly.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down.
