When to call us in Hampstead Norreys
Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.
What tends to prompt an enquiry:
- Expansion joints split through the centre of the bead
- Rain penetration at brick or block movement joints
- Layers of sealant in a movement joint
- Hardened, cracked sealant on exposed facades
Large sites such as West Berkshire Community Hospital, 5.8 miles south-west of Hampstead Norreys, have car parks, service roads and long elevations with movement joints in brick and panels.

Expansion joint sealing for commercial buildings in Hampstead Norreys
Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load so the product has to suit both the traffic and the movement. We’ll tell you if the edges need repairing before sealing, and phased work keeps areas in use. We work on brickwork movement joints, precast concrete panel joints and car park decks and ramps, and what we are called in for most is water getting into the wall through a failed joint and sealant pulling off the joint face. For commercial sealant work in Hampstead Norreys, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places such as Hampstead Norreys, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
How a job runs
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. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Hampstead Norreys can be grouped with others nearby. You will have a fixed quote before work starts.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- Send any specification or drawings in advance
- Move anything stored against the joints
- Share the asbestos register for older buildings

Advice
Warehouse floors and decks around Hampstead Norreys
Hampstead Norreys is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in. At about 49 miles from central London, Hampstead Norreys is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London.
Schools such as Hampstead Norreys C.E. Primary School have movement joints in their walls and floors that are easy to overlook.

Hampstead Norreys: questions and answers
Is hospital work, at somewhere like West Berkshire Community Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does a site in Hampstead Norreys have to shut while its joints are sealed?
Typically not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, which many sites require.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Is movement joint sealing guaranteed?
Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.
Different surfaces, different methods
Concrete and precast panel joints
Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.
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 in a colour confirmed for that product.
What we can’t put right
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Leaks coming from the membrane rather than the joint seal
- Broken or spalled joint edges, which need repairing before any sealant goes in
Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.
