Expansion joint sealing in Cheshunt, done properly
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Cheshunt. Most enquiries involve weathered movement joint sealant that no longer flexes and expansion joints split through the centre of the bead, across car park decks and ramps, precast concrete panel joints and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Cheshunt it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Towns such as Cheshunt usually have an industrial estate or a few business units, with warehouse floors and loading areas. Smaller units can’t stop work for long, so we plan around the occupier’s hours.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered
Must our site in Cheshunt 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. The phasing plan comes with the quote.
Do you take on work at healthcare sites like Cheshunt Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you reseal car park expansion joints?
Yes. We use a sealant designed for wheel loads and the expected movement, and phased work can be planned so parts of the car park stay in use.
How long will the joint resealing take?
The metres of joint, the access and the amount of removal decide it. Typically it takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Do you need expansion joint sealing in Cheshunt?
Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.
What tends to prompt an enquiry:
- Torn sealant in brick or block movement joints
- Previous reseals laid over old sealant
- Spalled or broken joint edges in floors and decks
- Sealant pulling off the joint face
Large sites such as Cheshunt Community Hospital (1.1 miles south-east of Cheshunt) have car parks, service roads and long elevations with movement joints in brick and panels.

Diagnose, treat, sign off

Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If you have more than one building in Cheshunt, they can often be done on the same visit, with one quote covering them. Tell us when the building is open and we will plan to suit.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.

Advice
What sets the cost
What shapes the price:
- How accessible the joints are
- Whether the work must be split into stages
- Removal of failed or old sealant
- Site requirements such as inductions and permits
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.
What to include in your enquiry
We can often quote from photographs and a few details. Please tell us:
- Where the site is, with the postcode
- Photos of the joints, close up and from further back
- Access details, including height
- Your programme or deadline
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or phone 01277 525 020 or use the quote form if you’d rather talk the job through.
Leave it or put it right?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.
Access often affects the price as much as the sealing: 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.

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.
Joints between different materials
Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces.
