When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Proprietary pre-formed expansion joint systems
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly before you book.

Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Raise snow-clearing blades over deck joints where possible
- Keep racking legs and heavy point loads off floor joints
- Record the sealant used and the date in the O&M file
- Reopen bays and walkways only after the stated cure time
Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. A sound seal keeps the joint working.

Our process
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- For older buildings, check the asbestos register before work
- Tell us what induction or permit system the site runs
- Move anything stored against the joints

FAQs: Hampstead Garden Suburb
Can you take on a job at a hospital such as Nuffield Health Highgate Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you take on work at estates like Brent Cross Shopping Park, close to Hampstead Garden Suburb?
Yes, sites like Brent Cross Shopping Park are within our area, along with the rest of Hampstead Garden Suburb. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Does the weather affect joint sealing?
A wet joint can’t be sealed properly, so external work waits for suitable conditions. We agree a revised date with you.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Can the building stay open while you work?
Typically, yes. We phase the work so most of the building stays in use.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.
Owners, agents and contractors
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
