From enquiry to sign-off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a job in Petts Wood, access comes first. Send the building rules and access times with your enquiry.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- 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, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Share your working hours and any access restrictions
- Have the specification and drawings to hand

How we handle expansion joint sealing in Petts Wood
Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. Site teams most often ask us about sealant pulling off the joint face and weathered movement joint sealant that no longer flexes, across precast concrete panel joints, podiums and floor movement joints and blockwork control joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Petts Wood, preparation and product choice get the time they need.
Areas such as a loading bay or car park deck in Petts Wood normally have to stay in use. We work through joints a section at a time, closing small areas in turn.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we will tell you they need repairing first. Failed sealant in a building in Petts Wood can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Quoting for work in Petts Wood
The price varies from site to site. It mainly depends on:
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Anything awkward about access or site hours
- A wide shot and a close-up of the area
- The product your specification calls for
- When you need the work done
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or email the details over with what you know.
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. 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.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Check joints after long freezing spells
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Note which joints were done, when, and with what
- Avoid parking heavy plant or pallets on joint lines
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in. Should you spot a problem, you can speak to us on 01277 525 020 or email the details over and send a picture.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it and it can affect the structure over time. Sealing the joint promptly stops it at source.
When to call us in Petts Wood
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again, so we check width and movement before quoting.
Clients usually get in touch after noticing one or more of the following:
- Hardened, cracked sealant on exposed facades
- Sealant peeling off one face of the joint
- Layers of sealant in a movement joint
- Leaks through car park deck joints onto the level below
In a school such as Crofton Junior School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
What your quote should include
- Their plan for phasing and protecting the area
- Their approach to joint depth and backing
- Which product they’ll use, and why it suits the joint
- Will CSCS-carded applicators be on site?

Your questions answered
Will you take on work at estates like Halo Business Park, close to Petts Wood?

How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How do I request a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.
What happens if it rains on the day?
A wet joint can’t be sealed properly so we’d rather rearrange than seal in the rain. We agree a revised date with you.
