Expansion joint sealing in Cold Harbour: the local picture
Cold Harbour is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint. Cold Harbour is about 30 miles from central London. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.
On a site such as Maidenhead Business Park, 1.1 miles east of Cold Harbour, the movement joints are in car park slabs, paving and building elevations. Hospital campuses such as St Mark's Hospital, 2.9 miles north-east of Cold Harbour, grow in stages, leaving movement joints wherever new blocks meet old. Across sites such as Grove Business Park, 1.5 miles south-east of Cold Harbour, floor and movement joints can be sealed in phases so units keep working.
Cold Harbour is about 3 miles west of Maidenhead, in Windsor and Maidenhead. If you’re looking for expansion joint sealing in Cold Harbour, we can help. We work across 60 places in Windsor and Maidenhead. Reading is covered too, around 9 miles from Cold Harbour.

Questions we’re asked in Cold Harbour
Is Cold Harbour too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work on a hospital site such as St Mark's Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you guarantee expansion joint work?
Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Cold Harbour. Several sites can go on one quote, which keeps the paperwork simple.
On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Cold Harbour need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What we need from you
- Let us know about inductions and permits
- Share the asbestos register for older buildings
- Make sure the joints can be reached

Advice
When to bring in a 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 typically costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Honest limits
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Waterproofing layers buried beneath the sealant
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Damaged metal nosings or cover plates over a joint
If you’re not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Record the sealant used and the date in the O&M file
- Act on the first tear or lifting edge rather than waiting
- Keep racking legs and heavy point loads off floor joints
- Inspect exposed joints once the cold weather has passed
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.

How the quote is worked out
The price varies from site to site. Expect it to depend on:
- The site’s rules and procedures
- Whether the work must be split into stages
- Distance, for remote addresses
- How much existing material needs removing
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- Your programme or deadline
- The product your specification calls for
- Drawings or a marked-up plan, if available
- Whether an asbestos survey exists
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email the details over.
