When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Waterproofing layers buried beneath the sealant
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Proprietary pre-formed expansion joint systems
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Expansion joint sealing in Tyttenhanger
If you need expansion joint sealing in Tyttenhanger, start with photos and joint lengths. We will come and look where photographs don’t show enough, then send a fixed quote that names the sealant. You can also phone 01277 525 020 or send details through our quote form to talk the joints through. We work on podiums and floor movement joints, precast concrete panel joints and blockwork control joints, and what we’re called in for most is expansion joints split through the centre of the bead and weathered movement joint sealant that no longer flexes. A specialist sealant contractor works differently from a general builder: in Tyttenhanger, that means joint design, primers and backing rod as standard.
Smaller community and commercial buildings around Tyttenhanger have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Places near Tyttenhanger
Also in Tyttenhanger
Surface by surface
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it.
Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.
Questions we are asked in Tyttenhanger
Do you take on work at healthcare sites like Kingsley Green Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is Tyttenhanger too small for you to travel to?
Not at all. Tyttenhanger is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
Do you reseal car park expansion joints?
Yes. We use a sealant designed for wheel loads and the expected movement.
Quoting for work in Tyttenhanger
Your fixed quote is built from the real scope. It allows for:
- Travel to remote or island sites
- Whether old sealant has to be cut out first
- The total length or number of joints
- Site requirements such as inductions and permits
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
What to include in your enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- A wide shot and a close-up of the area
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
- How the joints are reached, and at what height
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, call 01277 525 020 or use the quote form.
From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. For a building around Tyttenhanger, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Make sure the joints can be reached
- Tell us which areas need to stay in use
- Warn occupants and staff about the work

Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Inspect movement joints alongside other routine building checks
- Raise snow-clearing blades over deck joints where possible
- Act on the first tear or lifting edge rather than waiting
- Avoid parking heavy plant or pallets on joint lines
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.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.
Expansion joint sealing in Tyttenhanger: the local picture
Less than 3 miles from Tyttenhanger there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Rainfall across the South East, Tyttenhanger included, is lower than in many parts of the UK. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.
Another example is North Orbital Commercial Park, 1.1 miles to the west of Tyttenhanger, where floors and yards would be done in stages around the occupiers. For a store at a site such as The Albert Bygrave Retail Park, 0.8 miles to the south-west of Tyttenhanger, the service yard and goods-in area are where joints break down first. In a school such as Nicholas Breakspear School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
