About our expansion joint sealing in St George's Hill
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. If you’re dealing with water getting into the wall through a failed joint and debris jammed in movement joints, we can help, whatever the surface. Facilities teams, main contractors and managing agents in St George's Hill tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Small units near places like St George's Hill are often converted farm buildings with new concrete floors. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.
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.

Floors, slabs and movement joints in St George's Hill
St George's Hill 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 where de-icing salt is spread in winter, open joints let it in. Central London is about 18 miles from St George's Hill. Warehousing clusters around the motorways that ring and radiate from London.
For an estate such as Walton Community Hospital (2.1 miles north-east of St George's Hill), the joints in ramps, decks and long building elevations all need attention over time. Office parks like Wintersells Business Park (to the south-west of St George's Hill) have decks, ramps and clad elevations whose joints take movement every day.

St George's Hill: questions and answers
Will you take on work at estates like Wintersells Business Park, close to St George's Hill?
Yes, sites like Wintersells Business Park are within our area, along with the rest of St George's Hill. A few photographs and the unit address let us price the work.
Is St George's Hill too small for you to travel to?
Not at all. St George's Hill is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can you seal joints in cold or wet weather?
Weather matters for any external joint because a damp or frozen joint won’t take a proper bond. Indoor joints can typically carry on regardless.
Why do our movement joints keep failing?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Signs you need expansion joint sealing in St George's Hill
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks.
It’s worth sending us details if you spot any of the following:
- Water getting into the wall through a failed joint
- Debris jammed in movement joints
- Torn sealant in brick or block movement joints
- Previous reseals laid over old sealant
Schools such as Manby Lodge Infant School have movement joints in their walls and floors that are easy to overlook.

How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Work in places the size of St George's Hill is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- 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.
- Where areas have to stay open, we agree a phased sequence before starting.
- 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.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Tell staff and tenants when we will be in
- Tell us your opening times and when work is allowed

Related advice
Different surfaces, different methods
Podium joints
Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Plan racking layouts so feet don’t land on a joint
- Treat a small split as a warning, not a cosmetic issue
- Clear dirt from joint lines during routine cleaning
- Keep scrapers and ploughs from dragging across joint sealant
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.
On a multi-storey car park, a failed joint usually shows up as a leak onto the deck underneath. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Resealing early limits the damage.
Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
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.
What happens if it’s left?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. Tell us what has to stay open and we’ll plan around it. For buildings in places like St George's Hill, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
