About our expansion joint sealing in Perivale
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors. Site teams most often ask us about torn sealant in brick or block movement joints and layers of sealant in a movement joint, on precast concrete panel joints, car park decks and ramps and blockwork control joints. One point of contact handles commercial sealant work in Perivale from the first photos to the final walk-round, whether it’s one building or several.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up.
The 12-month guarantee covers our workmanship: 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.

What we are called out for in Perivale
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way, so we check width and movement before quoting.
These are often picked up first by site or facilities staff:
- Sealant peeling off one face of the joint
- Previous reseals laid over old sealant
- Debris jammed in movement joints
- Water getting into the wall through a failed joint
Campuses like University of West London, 1.9 miles to the south of Perivale, mix old and new buildings, with movement joints wherever they meet.
Questions to ask before you book
- The named product and why it was chosen
- Are they CHAS accredited or on Constructionline?
- What site paperwork they can supply
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Where floor joints take the most wear near Perivale
Perivale has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Basement car parks and service yards in London tend to be in use all working day, so the work is broken into short sections agreed with the building manager.
Estates like Phoenix Trading Estate (to the east of Perivale) combine warehouse slabs, yards and loading bays, all with joints under wheels. For a centre such as Westway Shopping Park, which lies west of Perivale, the service yard and car park joints typically need attention first.
Perivale is about 1 mile east of Greenford, in Greater London. Across the UB6 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Perivale is one of 764 places in Greater London on our list. Sites around London have their own page, roughly 10 miles from Perivale.
We cover the UB6, HA0 and W5 postcode districts for movement joints. Buildings on Lee Road, Wicket Road and Bilton Road are within our area. If your building is just outside Perivale, we cover Pitshanger (1 mile south), Brentham Garden Suburb (1 mile south-east), Sudbury Hill (1 mile north), Sudbury (1 mile north) and Greenford (1 mile west). Further afield, our area takes in London (10 miles east), City of Westminster (7 miles east), Marylebone (8 miles east), Kensington (6 miles south-east), St Pancras (9 miles east) and Shoreditch (10 miles east).
Local landmarks in Perivale
In Perivale, that means premises near Alperton Community School, Castle Bar Park and Brentham Clubhouse pub, among other places. Perivale’s nearest station is South Greenford station, about 0.8 miles south-west of the centre. A little further out are London Transport Museum Depot (2.8 miles south-east) and London Designer Outlet (1.9 miles north-east). For a walk, there’s Middle Lake and Castlebar Hill.
What happens if it’s left?
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Failed sealant in a building in Perivale can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
How a job runs
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. All of Greater London is in the ULEZ, and kerbside space in Perivale can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Warn occupants and staff about the work
- Point out parking and an unloading spot

Advice
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Crumbling edges that would give a new bead nothing sound to grip
- Movement on a scale no sealant is meant to absorb
- Damaged metal nosings or cover plates over a joint
If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
Joints and surfaces we work on
- Car park decks and ramps
- Brickwork movement joints
- Podiums and floor movement joints
- Precast concrete panel joints
- Cladding panel joints
- Blockwork control joints
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Your questions answered
Is a hospital such as Cygnet Hospital Ealing somewhere you can work?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you take on jobs in Perivale where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Do you reseal car park expansion joints?
Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed, and we’ll tell you if any edges need repairing first.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do the joint edges need to be sound before sealing?
Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we’ll say so when we quote.
Is movement joint sealing guaranteed?
The 12-month guarantee applies to the workmanship. Tell us right away if a joint we sealed gives trouble in that time.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
