Your questions answered
Is Latimer off your patch?
Not at all. Latimer is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Can you work on a hospital site such as Amersham Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
What guarantee do you give on joint sealing?
The 12-month guarantee applies to the workmanship. Tell us straight away if a joint we sealed gives trouble in that time.
What if the joint edges are damaged?
A bond is only as strong as the material behind it, so we’ll tell you if the edges need repairing before sealing. We flag it at the quote stage where we can see it.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Does the weather affect joint sealing?
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, so we plan with the forecast in mind.
How we handle expansion joint sealing in Latimer
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on blockwork control joints, precast concrete panel joints and podiums and floor movement joints, and the failures we’re asked to look at most are torn sealant in brick or block movement joints and new sealant over old, now failing. Whoever orders the work in Latimer, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places such as Latimer, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Looking after the joints
Keep the joints in good shape with a few simple steps:
- Raise snow-clearing blades over deck joints where possible
- Clear dirt from joint lines during routine cleaning
- Look over external and deck joints after a hard winter
- Include every elevation and deck joint in periodic inspections
Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth. Keeping the area coned off until then avoids tyre marks and damage.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.
Leave it or put it right?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. Tell us what has to stay open and we’ll plan around it. One visit to deal with every failing joint makes more sense than several trips to a place like Latimer. Photos of every joint help us quote for the whole job.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Doing it in-house
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
How a job runs
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Latimer, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- 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.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Share your working hours and any access restrictions
- Point out any areas we must not close
- Flag any permit to work we’ll need

Common problems we fix in Latimer
Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears, which is why depth control matters.
Clients normally get in touch after noticing something like this:
- Expansion joints split through the centre of the bead
- Sealant peeling off one face of the joint
- Car park joints leaking onto vehicles below
- Previous reseals laid over old sealant
For a school such as Little Chalfont Primary School, playground and building joints can be done in the holidays.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
- Their public liability cover
- Whether old or failed sealant will be cut out, not overlaid
