How we handle expansion joint sealing in Waltham Cross
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied. Most enquiries involve sealant pulling off the joint face and rain penetration at brick or block movement joints, on precast concrete panel joints, podiums and floor movement joints and cladding panel joints. Searching for sealant specialists in Waltham Cross? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Around places the size of Waltham Cross, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Raise snow-clearing blades over deck joints where possible
- Note which joints were done, when, and with what
- Put movement joints on the planned maintenance inspection round
- Keep traffic off new joints until the cure time is up
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file so future maintenance isn’t guesswork.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.

What happens if it’s left?
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too. We can price a patch and a full reseal side by side. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Work in places the size of Waltham Cross is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, 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.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Tell us what induction or permit system the site runs
- Let building users know which areas are affected
- Send asbestos survey details if the building is pre-2000

Common questions from Waltham Cross clients
Would you work within a site like Cheshunt Community Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Is a smaller place like Waltham Cross outside your area?
No. Places such as Waltham Cross are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work while the building is occupied?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Cost factors for movement joints
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Whether the work must be split into stages
- Joint width, depth and condition
- The total length or number of joints
- Whether old sealant has to be cut out first
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Before you send an enquiry
We can often quote from photos and a few details. It helps to include:
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
- Any specification or named product
- Whether the building will be occupied during the work
To get a fixed quote, speak to us on 01277 525 020 or send photos by email. Our quote form is another easy route.
What we’re called out for in Waltham Cross
Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way, so we check width and movement before quoting.
Most enquiries start with one or more of the following:
- Sealant peeling off one face of the joint
- Water dripping through deck or ramp joints
- Layers of sealant in a movement joint
- Spalled or broken joint edges in floors and decks
Schools such as Four Swannes Primary School have movement joints in their walls and floors that are easy to overlook.
What to look for in a quote
- Whether their applicators hold CSCS cards
- What level of public liability insurance do they hold?
- How joint depth will be controlled
- What the guarantee covers, and for how long
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
