Expansion joint sealing near Chipping
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Leaks coming from the membrane rather than the joint seal
- Damaged metal nosings or cover plates over a joint
- Changing the joint layout or spacing of a structure
If in doubt, speak to us on 01277 525 020 or email us and we will say what we think.

Across sites such as Buntingford Business Park, 1.3 miles to the south of Chipping, floor and movement joints can be sealed in phases so units keep working.

Different surfaces, different methods
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces priming where the maker calls for it.
Diagnose, treat, sign off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For a building around Chipping, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- 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
- Make sure the joints can be reached
- For older buildings, check the asbestos register before work
- Tell us what induction or permit system the site runs
Quotes
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Related advice
Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Brief car park operatives to protect joint lines during winter clearance
- Keep racking legs and heavy point loads off floor joints
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Leave barriers in place until fresh joint sealant has cured
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. Should you spot a problem, you can give us a call on 01277 525 020 or email a schedule or drawings and send a picture.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster. Sealing early protects the edges.
How the quote is worked out
The price varies from site to site. Expect it to depend on:
- Travel to remote or island sites
- Any access equipment needed
- The site’s rules and procedures
- Working within restricted access windows
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Details that help us quote
To price the job accurately, we need a clear picture of the site. Useful things to include:
- When you need the work done
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
To get a fixed quote, give us a call on 01277 525 020 or email the details over, telling us the site location and the nature of the job. You can also send details through our quote form.
Questions we’re asked in Chipping
Will you take on work at estates like Park Farm Industrial Estate, close to Chipping?
Yes. Our area takes in Chipping and its surroundings, with estates and business parks such as Park Farm Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is Chipping too far out for you?
No. Places such as Chipping are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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. Removing asbestos is a job for asbestos specialists, not us.
Can you work while the building is occupied?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
What will the job cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
