Expansion joint sealing near Selhurst
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Diagnose, treat, sign off
Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. In Selhurst, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Getting the site ready
- Send your site hours and access windows
- For older buildings, check the asbestos register before work
- Move anything stored against the joints

About our expansion joint sealing in Selhurst
For movement joints in Selhurst, photos and approximate lengths are the best start. Send them through our quote form, and we’ll arrange a site visit if needed, then send a fixed quote that names the sealant. You can also speak to us on 01277 525 020 or use the quote form to talk the joints through. Site teams most often ask us about damp inside where a wall movement joint has failed and joints where the bead has lost adhesion, across car park decks and ramps, brickwork movement joints and cladding panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Selhurst is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
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, so it pays to act early.
Every job we finish is backed by a 12-month workmanship guarantee, in Selhurst as everywhere else we work. If our installation lets you down in that time, we return and fix it.

When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Damaged metal nosings or cover plates over a joint
- Concrete or masonry repairs along the arrises
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we will tell you honestly.

Selhurst: questions and answers
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them.
Does your area include sites such as Chaffinch Business Park, near Selhurst?
Yes. Estates, retail parks and business parks around Selhurst, Chaffinch Business Park among them, are all within reach. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
What happens if it rains on the day?
The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
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.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Site staff or a sealant specialist?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
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.
Surface by surface
Joints between different materials
Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement, and tell you if edges need repairing first.
Where floor joints take the most wear near Selhurst
Less than 3 miles from Selhurst there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Few London car parks or loading bays can be taken out of use for more than a short spell, so joints are sealed in sections with each area handed back once cured.
Large sites such as Shirley Oaks Hospital (to the south-east of Selhurst) have car parks, service roads and long elevations with movement joints in brick and panels. Campuses like King's College London, 4.8 miles north of Selhurst, mix old and new buildings, with movement joints wherever they meet. On a site such as Chaffinch Business Park, which lies east of Selhurst, the movement joints are in car park slabs, paving and building elevations.

Why deal with it now?
Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex and soon lets go. We cut out the old seal and prepare the faces every time. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
