High Leigh: questions and answers
Would you work within a site like Hertford County Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Is Hilgrove Business Park, near High Leigh, within your area?
Yes. Estates, retail parks and business parks around High Leigh, Hilgrove Business Park among them, are all within reach. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Do you offer coloured sealant?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Mastic Doctor has sealed movement joints since 2005 for contractors, facilities managers and owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. The enquiries we see most involve brittle, chalky sealant on external joints and expansion joints split through the centre of the bead, across blockwork control joints, podiums and floor movement joints and car park decks and ramps. Searching for sealant specialists in High Leigh? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around smaller places such as High Leigh, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

- Clear photos of the problem areas

- What the building is and how it’s used
- Access details, including height
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call 01277 525 020 or email a schedule or drawings to discuss it first.
Where floor joints take the most wear near High Leigh
High Leigh sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. Central London is about 18 miles from High Leigh. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
Schools like Westfield Community Primary School often have long brick elevations with movement joints that age quietly. For an estate such as Hertford County Hospital (3.5 miles north-west of High Leigh), the joints in ramps, decks and long building elevations all need attention over time. For buildings at a park such as Hilgrove Business Park, 2.2 miles to the south-east of High Leigh, brick and panel movement joints are easy to forget until one leaks.
High Leigh is about 1 mile north-west of Hoddesdon, in Hertfordshire. Commercial clients in High Leigh use us for work on movement joints. 371 places across Hertfordshire fall within our area, High Leigh among them. London is covered too, some 18 miles away.

Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. 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. Older rural buildings around High Leigh move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Diagnose, treat, sign off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. Jobs in and around smaller places like High Leigh are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- 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.
- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- Tell staff and tenants when we will be in
- Confirm the product named in the specification
- Make sure the joints can be reached

Different surfaces, different methods
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. They take a low-modulus sealant with a movement class to suit, with backing rod setting the depth.
