About our expansion joint sealing in Downton
Long runs of brick or block have movement joints built in, 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 with primer where the maker calls for it. The enquiries we see most involve joints where the bead has lost adhesion and weathered movement joint sealant that no longer flexes, on car park decks and ramps, cladding panel joints and podiums and floor movement joints. One point of contact handles commercial sealant work in Downton from the first photos to the final walk-round, whether it’s one building or several.
Halls, schools and small commercial buildings near places like Downton have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Downton, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- 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.

Questions we are asked in Downton
Can you take on a job at a hospital such as Lymington New Forest 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.
Is Downton off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
How long will the joint resealing take?
The metres of joint, the access and the amount of removal decide it. Typically it takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
What happens if it rains on the day?
Weather matters for any external joint. Indoor joints can usually carry on regardless.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Concrete or masonry repairs along the arrises
- A joint that has to be widened or re-detailed before it can work
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Not sure which it is? You can give us a call on 01277 525 020 or email us and we will tell you honestly.

Signs you need expansion joint sealing in Downton
Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability.
It’s worth sending us details if you spot any of the following:
- Previous reseals laid over old sealant
- Sealant peeling off one face of the joint
- Car park joints leaking onto vehicles below
- Spalled or broken joint edges in floors and decks
Estates like Gore Road Industrial Estate (2.4 miles west of Downton) combine warehouse slabs, yards and loading bays, all with joints under wheels.

Traffic, movement and joints around Downton
Downton lies within about 1 mile of the sea. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so it pays to keep them sealed. Downton is in the South East, one of the UK’s drier regions. 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.
For an estate such as Lymington New Forest Hospital (3.7 miles north-east of Downton), the joints in ramps, decks and long building elevations all need attention over time. Schools such as Hordle CofE (VA) Primary School have movement joints in their walls and floors that are easy to overlook.
Downton is about 3 miles west of Lymington, in Hampshire. Across the SO41 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Downton is one of 723 places we cover in Hampshire. We also cover Southampton, around 16 miles from Downton.
We cover the SO41 postcode districts. Buildings on Hordle Lane and Shorefield Road are within our area for movement joints.

Bigger towns within reach include Totton (13 miles north), Lymington (3 miles east), Hythe (13 miles north-east), Ringwood (10 miles north-west), Dibden Purlieu (12 miles north-east) and Marchwood (13 miles north-east).

What the job involves on each surface
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in and flag any joint that seems undersized.
Podium joints
Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.

What else we do in Downton
Doing it in-house
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 where general trades tend to cut corners.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
For managing agents and facilities managers
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
