Expansion joint sealing for commercial buildings in Egham
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. We work on blockwork control joints, podiums and floor movement joints and precast concrete panel joints, and the failures we’re asked to look at most are new sealant over old, now failing and joints packed with grit and debris. Looking for mastic applicators who cover Egham? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In Egham, as in most towns, brickwork and panel movement joints on public and commercial buildings age quietly. A split or hardened joint lets rain into the wall, and it can no longer take up the movement.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Cracking or settlement that calls for an engineer’s assessment
- Changing the joint layout or spacing of a structure
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.

Questions about Egham
Do we have to stop operations in Egham while the joints are sealed?
Typically not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.
Is hospital work, at somewhere like Ashford Hospital, something you do?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does the weather affect the work?
Outside, 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.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Can you seal joints in cold or wet weather?
A wet joint can’t be sealed properly, so external work waits for suitable conditions. We agree a revised date with you.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
When to call us in Egham
Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way.
If one of these sounds familiar, it’s time for a closer look:
- New sealant over old, now failing
- Damp inside where a wall movement joint has failed
- Weathered movement joint sealant that no longer flexes
- Expansion joints filled with dirt and stones
University campuses such as Royal Holloway University (0.8 miles west of Egham) have car parks, paved walkways and building elevations with movement joints.
What your quote should include
- Is the sealant right for the movement and the substrate?
- Whether their applicators hold CSCS cards
- Will failed sealant be removed rather than covered?
- Whether primer will be used where the manufacturer specifies it
What the job involves on each surface
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. They take a low-modulus sealant with a movement class to suit, with backing rod setting the depth.
General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Traffic, movement and joints around Egham
Egham sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in. At least three named trading, business or retail sites lie within about 3 miles of Egham. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
Another example is Hawthorne Trade Park, which lies north-east of Egham, where floors and yards would be done in stages around the occupiers. A healthcare site such as Ashford Hospital, 3.5 miles to the east of Egham, depends on car parks, ramps and service yards whose joints take traffic all day.

Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit. 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. Town-centre premises in Egham may have limited parking, so tell us what’s nearby. On estates and business parks it’s usually simpler.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- 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.
Preparing the site
- For older buildings, check the asbestos register before work
- Tell staff and tenants when we will be in
- Clear stock, furniture or equipment away from the joints
