Expansion joint sealing near Little Hadham
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Surface by surface
Joints between different materials
Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces, with primer where specified.
Car park decks and ramps
Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again flagging broken edges along the way.
How we handle expansion joint sealing in Little Hadham
Buildings and slabs are never completely still: 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, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. We work on podiums and floor movement joints, car park decks and ramps and cladding panel joints, and the usual reasons a site gets in touch are damp inside where a wall movement joint has failed and debris jammed in movement joints. A single leaking joint is often how a building in Little Hadham first comes to us: we look at the rest while we’re there and tell you what we find.
Jobs around smaller places like Little Hadham are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

FAQs: Little Hadham
Is Little Hadham too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can you take on a job at a hospital such as Herts and Essex Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you seal car park deck joints?
Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement with bays phased so the car park keeps operating.
Can a joint be sealed if the edges are broken?
The edges have to be sound. Where they’ve broken up, we’ll tell you they need repairing first, so the new seal has something to grip.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
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 it all comes out first.

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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, which is what makes a joint last.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Little Hadham, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Tell us your opening times and when work is allowed
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints

- Cracking or settlement that calls for an engineer’s assessment
- Waterproofing layers buried beneath the sealant
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.

Why it’s worth doing now in Little Hadham
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we will tell you honestly. Around Little Hadham, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
