Expansion joint sealing in New Barn
Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. We work on brickwork movement joints, car park decks and ramps and podiums and floor movement joints, and the usual reasons a site gets in touch are rain penetration at brick or block movement joints and spalled or broken joint edges in floors and decks. A specialist sealant contractor works differently from a general builder: on jobs in New Barn, preparation and product choice get the time they need.
In a smaller place such as New Barn, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in New Barn, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- The failed seal is removed and both faces are cleaned until sound and dry, 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 sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Proprietary pre-formed expansion joint systems
- A joint that has to be widened or re-detailed before it can work
If you are not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer before you book.

What else we do in New Barn
What affects the price in New Barn
Each job is priced on its own details. The main factors are:
- The size and state of each joint
- Quantities, in metres or numbers
- The product specified
- Site requirements such as inductions and permits
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
- The postcode of the building
- The type of building and who uses it
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Questions we’re asked in New Barn
Does your area include sites such as Fawkham Business Park, near New Barn?
Yes. Our area takes in New Barn and its surroundings, with estates and business parks such as Fawkham Business Park included. A few photos and the unit address let us price the work.
Is New Barn off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it.
Is movement joint sealing guaranteed?
The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What the job involves on each surface
Car park decks and ramps
Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again, and we will tell you if any edges need repairing first.
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. They take a low-modulus sealant with a movement class to suit.
Do you need expansion joint sealing in New Barn?
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’s common on joints sealed in a hurry.
Clients normally get in touch after noticing one or more of the following:
- Layers of sealant in a movement joint
- Joints where the bead has lost adhesion
- Joints packed with grit and debris
- Water dripping through deck or ramp joints
Across sites such as Bowes Industrial Centre, 2.7 miles south-east of New Barn, floor and movement joints can be sealed in phases so units keep working.
What your quote should include
- Their pre-qualification and accreditations
- How they handle RAMS and site documents
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether primer will be used where the manufacturer specifies it
Maintenance after handover
Regular inspection catches problems early. In particular:
- Keep racking legs and heavy point loads off floor joints
- Report split or peeling joint sealant early
- Check joints after long freezing spells
- Inspect movement joints alongside other routine building checks
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. Should you spot a problem, you can phone 01277 525 020 or email drawings and photos and send a picture.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.
