Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Our process
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. Rural sites near Whempstead may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Send your site hours and access windows
- Make sure the joints can be reached
- Flag any permit to work we’ll need

Halls, schools and small commercial buildings near places like Whempstead have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Common questions from Whempstead clients
Is Astonbury Farm & Business Park, near Whempstead, within your area?
Yes. Estates, retail parks and business parks around Whempstead, Astonbury Farm & Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Is Whempstead off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
What guarantee do you give on joint sealing?
It’s backed by our 12-month guarantee. Tell us straight away if a joint we sealed gives trouble in that time.
Do you need expansion joint sealing in Whempstead?
Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.
Look out for the following:
- Water getting into the wall through a failed joint
- Brittle, chalky sealant on external joints
- Previous reseals laid over old sealant
- Arrises breaking up along floor joints
At places like Warrenwood Industrial Estate, 2.9 miles south of Whempstead, joints are sealed a section at a time so operations carry on.

Cost factors for movement joints
These are the things that shape the price:
- Travel to remote or island sites
- How much existing material needs removing
- The size and state of each joint
- The product specified
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
Before you send an enquiry
However big the job, the same details help:
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
- Clear photographs of the problem areas
- Whether an asbestos survey exists

What happens if it’s left?
Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s typically not far behind. We can price a patch and a full reseal side by side. Converted and older buildings near places like Whempstead tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you’re ready.

When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Joints too narrow for the movement, which need redesigning by the engineer
- Crumbling edges that would give a new bead nothing sound to grip
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If you are not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer.
What we seal
- Blockwork control joints
- Cladding panel joints
- Brickwork movement joints
- Precast concrete panel joints
- Car park decks and ramps
- Podiums and floor movement joints
How the job changes by 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.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces, with primer where specified.
