Your questions answered
Will you take on work at estates like The Station Shopping Park, close to Chalkhouse Green?
Yes. Our area takes in Chalkhouse Green and its surroundings, with estates and business parks such as The Station Shopping Park included. A few photographs and the unit address let us price the work.
Can you take on a job at a hospital such as Battle 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.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Can weather delay the job?
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. Internal work is far less affected.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Expansion joint sealing in Chalkhouse Green, done properly
Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. 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, primed where the manufacturer specifies. We work on blockwork control joints, cladding panel joints and car park decks and ramps, and what we are called in for most is chipped joint edges on forklift routes and sealant pulling off the joint face. A single leaking joint is often how a building in Chalkhouse Green first comes to us: we look at the rest while we’re there and tell you what we find.
Halls, schools and small commercial buildings near places like Chalkhouse Green have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Signs you need expansion joint sealing in Chalkhouse Green
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears, which is why depth control matters.
Most enquiries start with one or more of the following:
- Spalled or broken joint edges in floors and decks
- Previous reseals laid over old sealant
- Brittle, chalky sealant on external joints
- Torn sealant in brick or block movement joints
Large sites such as Battle Hospital (2.8 miles south of Chalkhouse Green) have car parks, service roads and long elevations with movement joints in brick and panels.
What your quote should include
- Their plan for phasing and protecting the area
- Is the sealant right for the movement and the substrate?
- Their public liability cover
- The terms of the workmanship guarantee
Why it’s worth doing now in Chalkhouse Green
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. Around Chalkhouse Green, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

How the quote is worked out
Quotes vary with the job. It mainly depends on:
- Whether old sealant has to be cut out first
- How much there is to seal
- Access and working height
- Working within restricted access windows
A quote for movement joints depends on quantities, condition and access. Ask us for a fixed quote.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- The product your specification calls for
- How the joints are reached, and at what height
- The type of building and who uses it
- Where the site is, with the postcode
To get a fixed quote, ring 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. Our quote form is another easy route.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep racking legs and heavy point loads off floor joints
- Keep traffic off new joints until the cure time is up
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Check joints after long freezing spells
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 the next reseal starts with the facts.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors, well after the seal first opened. Resealing promptly prevents internal damage.
Our process
Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Chalkhouse Green are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First the joints are inspected, widths measured and the type of failure noted.
- 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.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Tell us what induction or permit system the site runs
- Share your working hours and any access restrictions
- Agree which areas must stay open
