About our expansion joint sealing in Stanborough
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on car park decks and ramps, blockwork control joints and cladding panel joints, and the failures we are asked to look at most are torn sealant in brick or block movement joints and spalled or broken joint edges in floors and decks. Searching for sealant specialists in Stanborough? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Halls, schools and small commercial buildings near places like Stanborough have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Your questions answered
Is Stanborough too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Are the floor joints in an older unit in Hatfield worth resealing?
In most cases it is, if the edges haven’t broken up too far. We will look at the joints, recommend a product for the traffic and movement, and say if any edges need repair before sealing.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Which sealant will you use?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How do we ask for a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
What affects the price in Stanborough
A fixed quote reflects the actual work. It takes account of:
- How much existing material needs removing
- Induction, permit and paperwork requirements
- Whether the work must be split into stages
- The total length or number of joints
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
Details that help us quote
However big the job, these details speed things up:
- Drawings or a marked-up plan, if available
- A wide shot and a close-up of the area
- Where the site is, with the postcode
- The product your specification calls for
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
Surface by surface
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it.
Joints between different materials
Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement, and confirm it in the quote.
For managing agents and facilities managers
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Common problems we fix in Stanborough
Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.
If one of these sounds familiar, it’s time for a closer look:
- New sealant over old, now failing
- Chipped joint edges on forklift routes
- Sealant peeling off one face of the joint
- Rain penetration at brick or block movement joints
At a retail site such as Oldings Corner Retail Park, 0.8 miles to the south of Stanborough, joints in car parks, service yards and sales floors carry cars, cages and trolleys every day.
What to look for in a quote
- Whether their applicators hold CSCS cards
- What the guarantee covers, and for how long
- Proof of insurance
- Their plan for phasing and protecting the area
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Smaller jobs around Stanborough can be grouped with others nearby. You will have a fixed quote before work starts.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- 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.
Before we start on site
- Tell us what induction or permit system the site runs
- Tell us which areas need to stay in use
- Arrange parking or a loading space
Getting a fixed quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

After the work
For the best life from the joints:
- Put movement joints on the planned maintenance inspection round
- Reopen bays and walkways only after the stated cure time
- Record the sealant used and the date in the O&M file
- Clear dirt from joint lines during routine cleaning
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in. Should you spot a problem, you can call the office on 01277 525 020 or email drawings and photos and send a picture.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.
