About our expansion joint sealing in Crowborough
We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it. We work on cladding panel joints, brickwork movement joints and blockwork control joints, and the usual reasons a site gets in touch are joints packed with grit and debris and layers of sealant in a movement joint. Looking for mastic applicators who cover Crowborough? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In a town the size of Crowborough, floor joints are mostly in industrial and trade units, supermarkets and car parks. Small units are often busy, so joints are done at times that suit the occupier.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common problems we fix in Crowborough
Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability.
Most enquiries start with something like this:
- Damp inside where a wall movement joint has failed
- Debris jammed in movement joints
- Hardened, cracked sealant on exposed facades
- New sealant over old, now failing
Parks like Crowborough Business Park, 0.6 miles north of Crowborough, combine paved areas, car parks and building elevations, each with joints that move.
What to look for in a quote

- Their approach to joint depth and backing
- Will CSCS-carded applicators be on site?
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Proprietary pre-formed expansion joint systems
- Cracking or settlement that calls for an engineer’s assessment
- A joint that has to be widened or re-detailed before it can work
If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we will give you a straight answer.

Why it’s worth doing now in Crowborough
Resealing is usually the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we’ll tell you they need repairing first. Many buildings in towns like Crowborough have been extended or altered, and joints where old meets new tend to fail first. Resealing them early protects the building behind.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Why clients in Crowborough choose us
- Old sealant cut out, never sealed over
- Work to your specification and the manufacturer’s guidance
- A range of standard colours, depending on the product
- Workmanship guaranteed for 12 months

Floors, slabs and movement joints in Crowborough
Less than 3 miles from Crowborough there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Crowborough is about 33 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Questions about Crowborough
Will you take on work at estates like Crowborough Business Park, close to Crowborough?
Yes, sites like Crowborough Business Park are within our area, along with the rest of Crowborough. A few photographs and the unit address let us price the work.
Must our site in Crowborough stop work while the joints are done?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Can you work while the building is occupied?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
Why do our movement joints keep failing?
Normally the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.
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.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Town-centre premises in Crowborough may have limited parking, so tell us what’s nearby. Industrial and business units normally have yard or car park space.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- The failed seal is removed and both faces are cleaned until sound and dry, 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.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Tell us what induction or permit system the site runs
- Tell us which areas need to stay in use
