Expansion joint sealing for Maple Cross sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Should maintenance staff do it?
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.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
About our expansion joint sealing in Maple Cross
Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. If you have debris jammed in movement joints and water dripping through deck or ramp joints, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Maple Cross tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Halls, schools and small commercial buildings near places like Maple Cross have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

On site: what to expect
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Maple Cross can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- 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.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Before we start on site
- Tell us your opening times and when work is allowed
- Explain the parking and delivery arrangements

FAQs: Maple Cross
Will you take on work at estates like Woodcock Hill Industrial Estate, close to Maple Cross?

Is hospital work, at somewhere like Harefield Hospital, something you do?
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.
Can one quote cover more than one building?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Do you use silicone or polyurethane in movement joints?
Whatever suits the joint and the specification. The quote states the sealant and its movement class so there are no surprises.
Why it’s worth doing now in Maple Cross
A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Older rural buildings around Maple Cross move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why us?
- One phone line for London, the South East and Scotland
- Over 20 years of commercial sealing
- Colour agreed before work starts

Common problems we fix in Maple Cross
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes, and it’s common on joints sealed in a hurry.
Clients normally get in touch after noticing one or more of the following:
- Rain penetration at brick or block movement joints
- Expansion joints split through the centre of the bead
- Leaks through car park deck joints onto the level below
- Sealant peeling off one face of the joint
A healthcare site such as Harefield Hospital (1.6 miles south-east of Maple Cross) depends on car parks, ramps and service yards whose joints take traffic all day.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- Whether primer will be used where the manufacturer specifies it
- What site paperwork they can supply
- Which product they’ll use, and why it suits the joint
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Keep scrapers and ploughs from dragging across joint sealant
- Plan racking layouts so feet don’t land on a joint
- Reopen bays and walkways only after the stated cure time
- Put movement joints on the planned maintenance inspection round
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- Whether old sealant has to be cut out first
- Site requirements such as inductions and permits
- Access and working height
- Distance, for remote addresses
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- Any dates the work must fit around
- Any specification or named product
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email drawings and photos.
