From enquiry to sign-off
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 usually takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. If others near Haultwick need work, visits can be combined. You’ll have a fixed quote before work starts.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Confirm the product named in the specification

Advice
How the quote is worked out
These are the things that shape the price:
- How much there is to seal
- Joint width, depth and condition
- Location, for remote and island sites
- The site’s rules and procedures
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- When you need the work done
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older
- Access details, including height
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or send photos by email.
What we are called out for in Haultwick
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.
Common reasons buildings call us in:
- Water dripping through deck or ramp joints
- Hardened, cracked sealant on exposed facades
- Sealant pulling off the joint face
- Spalled or broken joint edges in floors and decks
Schools such as Munden Church of England Voluntary Controlled Primary School have movement joints in their walls and floors that are easy to overlook.

Your questions answered
Is Haultwick off your patch?
Not at all. Haultwick is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
What documents will you need to give us for a job in Haultwick?
RAMS, insurance certificate, CSCS details: list what the site needs and we will confirm it with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Why has the sealant in our expansion joints split?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first since each needs a different fix.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:
- Changing the joint layout or spacing of a structure
- Cracking or settlement that calls for an engineer’s assessment
- Leaks coming from the membrane rather than the joint seal
If in doubt, ring 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
Surfaces we seal
- Cladding panel joints
- Car park decks and ramps
- Brickwork movement joints
- Podiums and floor movement joints
- Blockwork control joints
- Precast concrete panel joints
Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Leave barriers in place until fresh joint sealant has cured
- Avoid parking heavy plant or pallets on joint lines
- Keep stones and debris out of open joint lines
- Raise snow-clearing blades over deck joints where possible
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file so future maintenance isn’t guesswork.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it and it can affect the structure over time. Resealing early limits the damage.
Expansion joint sealing in Haultwick: the local picture
The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint. Central London is about 27 miles from Haultwick. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift.
In and around Haultwick, the right filler or sealant for each joint depends on the traffic and the movement it takes.
Haultwick is about 5 miles east of Stevenage, in Hertfordshire. Haultwick sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else.

When to bring in a specialist
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.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
