Expansion joint sealing in Hersden
Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels. If the arrises are already broken, we will say so before sealing and phasing can keep areas working. We work on precast concrete panel joints, blockwork control joints and cladding panel joints, and the failures we’re asked to look at most are leaks through car park deck joints onto the level below and joints packed with grit and debris. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Hersden, that means joint design, primers and backing rod as standard.
Around Hersden, most floor and movement joint jobs are single buildings or yards, so we gather photographs and measurements first. That way the right materials come on the day and the job is done in one visit where possible.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

FAQs: Hersden
Is Hersden too far out for you?
No. Places such as Hersden are covered as much as the big towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Can you take on a job at a hospital such as St Martins Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
What will the job cost?
We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.
What site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
Surface by surface
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them, and tell you if edges need repairing first.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.
Do you need expansion joint sealing in Hersden?
Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Site and facilities staff are often the first to spot these:
- Movement joints with split or torn sealant
- Spalled or broken joint edges in floors and decks
- Debris jammed in movement joints
- Car park joints leaking onto vehicles below
Estates like Canterbury Industrial Park (0.6 miles east of Hersden) combine warehouse slabs, yards and loading bays, all with joints under wheels.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Who will actually carry out the work
- The named product and why it was chosen
- Health and safety accreditation such as CHAS
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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.
Cost factors for movement joints
Your fixed quote is built from the real scope. It takes account of:
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
- Whether the work must be split into stages
- How accessible the joints are
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- What the building is and how it’s used
- Drawings or a marked-up plan, if available
- When you need the work done
- The postcode of the building
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email the details over with what you know.
How a job runs
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. If neighbouring businesses or buildings around Hersden need work too, visits can be combined. Tell us your site hours and we will plan around them.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- 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.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand
- Share your working hours and any access restrictions
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

What we can’t put right
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Cracking or settlement that calls for an engineer’s assessment
- Damaged metal nosings or cover plates over a joint
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If you’re not sure, just call 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
