How we handle expansion joint sealing in Hatchet Green
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. We work on brickwork movement joints, blockwork control joints and cladding panel joints, and the failures we’re asked to look at most are expansion joints filled with dirt and stones and water getting into the wall through a failed joint. Searching for sealant specialists in Hatchet Green? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
In and around smaller places like Hatchet Green, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Hatchet Green: questions and answers
Is a smaller place like Hatchet Green outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work at a site such as Downton Business Centre, by Hatchet Green?
Yes. Estates, retail parks and business parks around Hatchet Green, Downton Business Centre among them, are all within reach. Photos and a short description are enough for a first look.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
What if there’s asbestos in the old mastic?
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. Removing asbestos is a job for asbestos specialists, not us.
What guarantee do you give on joint sealing?
The workmanship is guaranteed for 12 months from sign-off. Regular sweeping and inspection help the joints last.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Waterproofing layers buried beneath the sealant
- Joints too narrow for the movement, which need redesigning by the engineer
- Crumbling edges that would give a new bead nothing sound to grip
If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
What we seal
- Cladding panel joints
- Precast concrete panel joints
- Car park decks and ramps
- Brickwork movement joints
- Blockwork control joints
- Podiums and floor movement joints
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Quoting for work in Hatchet Green
To price the job, we consider:
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
- How much there is to seal
- Distance, for remote addresses
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What we need to price the job
It doesn’t need to be a full survey. These details are enough to start:
- Whether an asbestos survey exists
- Any specification or named product
- Clear photos of the problem areas
- The site address and postcode
To get a fixed quote, call 01277 525 020 or use the quote form, telling us the site location and the nature of the job. Our quote form is another easy route.
On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and we clear our waste as we work. Jobs in and around smaller places like Hatchet Green are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Share your working hours and any access restrictions
- Share the asbestos register for older buildings
- Tell staff and tenants when we’ll be in
Getting a fixed quote
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.

Office parks like Downton Business Centre (2.2 miles north-west of Hatchet Green) have decks, ramps and clad elevations whose joints take movement every day. For a school such as Hale Primary School, playground and building joints can be done in the holidays.

How the job changes by surface
Joints between different materials
Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement, with primer where specified.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing and flag any joint that seems undersized.
