Expansion joint sealing for commercial buildings in Haverstock
Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it, and we will confirm the choice in the quote. If you are dealing with arrises breaking up along floor joints and leaks through car park deck joints onto the level below, we can put it right, on blockwork control joints, cladding panel joints and podiums and floor movement joints alike. Looking for mastic applicators who cover Haverstock? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around Haverstock, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up.
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 spell out the cover before we begin.

Your questions answered
Do you take on jobs in Haverstock where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry.
Does your area include sites such as Regis Road Business Park, near Haverstock?
Yes. Our area takes in Haverstock and its surroundings, with estates and business parks such as Regis Road Business Park included. A few photographs and the unit address let us price the work.
What guarantee do you give on joint sealing?
The 12-month guarantee applies to the workmanship. Tell us right away if a joint we sealed gives trouble in that time.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
What sealant do you use in movement joints?
It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane, and the specification has the final say.
On site: what to expect
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Each joint is inspected and handed over with our 12-month guarantee.
Preparing the site
- Flag any permit to work we’ll need
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand
Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

How the job changes by surface
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability, and we’ll confirm the colours available for the specified product.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Leaks coming from the membrane rather than the joint seal
- Joints too narrow for the movement, which need redesigning by the engineer
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly before you book.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Report split or peeling joint sealant early
- Inspect exposed joints once the cold weather has passed
- Keep scrapers and ploughs from dragging across joint sealant
- Keep product details with the building records for the next reseal
Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint and we will tell you when each bay or area can reopen. Barriers left in place until then protect the finish.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.
Floors, slabs and movement joints in Haverstock
In London, decks, bays and service yards usually have to keep running, so we seal in sections and hand areas back as each cures.

Another example is Bush Industrial Estate, 1.7 miles to the north-east of Haverstock, where floors and yards would be done in stages around the occupiers. Hospitals like Royal Free Hospital (0.6 miles north of Haverstock) have multi-storey or surface car parks whose joints carry vehicles round the clock.
