Site staff or a sealant 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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Leave it or put it right?
Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we’ll tell you honestly. One visit to deal with every failing joint makes more sense than several trips to a place like St Mary in the Marsh, rather than one at a time. Send photographs of each area and we will quote for the lot.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Why us?
- Old sealant cut out, never sealed over
- RAL and finish matching where the product range allows
- Our applicators hold CSCS cards
- One contact handling all your sites
When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- A joint that has to be widened or re-detailed before it can work
- Concrete or masonry repairs along the arrises
- Movement on a scale no sealant is meant to absorb
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Where floor joints take the most wear near St Mary in the Marsh
St Mary in the Marsh sits close to the coast, within about 2 miles. Open joints in coastal car parks and yards let in salt-laden water as well as grit, which is why split joints are worth sealing before the edges deteriorate. Rainfall across the South East, St Mary in the Marsh included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.
Around St Mary in the Marsh, each joint gets a filler or sealant matched to what crosses it and how much it moves. Schools such as The Marsh Academy have movement joints in their walls and floors that are easy to overlook.

What else we do in St Mary in the Marsh
Questions we are asked in St Mary in the Marsh
Must our site in St Mary in the Marsh stop work while the joints are done?
In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.
Does a coastal location like St Mary in the Marsh affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What exactly is a movement joint?
The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped, and the sealing method is much the same.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Can you work on car park ramps and decks?
Yes. We use a sealant designed for wheel loads and the expected movement.
Why do our movement joints keep failing?
The way it has failed normally tells us why: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.
Surface by surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors, with a flexible sealant where movement is larger.
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.
