What affects the price in Pin Green
A fixed quote reflects the actual work. It allows for:
- Whether old sealant has to be cut out first
- The product specified
- The total length or number of joints
- Backing rod, priming and other preparation
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.
Details that help us quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Approximate linear metres or a joint schedule
- What the building is and how it’s used
- Your programme or deadline
- Any specification or named product
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Honest limits
Honesty saves time and money. New sealant won’t cure:
- Changing the joint layout or spacing of a structure
- Leaks coming from the membrane rather than the joint seal
- Broken or spalled joint edges, which need repairing before any sealant goes in
If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think before you book.
What we seal
- Brickwork movement joints
- Blockwork control joints
- Car park decks and ramps
- Podiums and floor movement joints
- Precast concrete panel joints
- Cladding panel joints
Do you need expansion joint sealing in Pin Green?
The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.
It’s worth sending us details if you spot any of the following:
- Debris jammed in movement joints
- Car park joints leaking onto vehicles below
- Layers of sealant in a movement joint
- Movement joints with split or torn sealant
In a school such as Trotts Hill Primary and Nursery School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
What your quote should include
- Which product they’ll use, and why it suits the joint
- How the existing material will be dealt with
- Their public liability cover
- Their pre-qualification and accreditations
Surface by surface
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.
Joints between different materials
Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement.
From enquiry to sign-off
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Several jobs near Pin Green can be grouped on one trip. Mention the building’s opening times and we will work within them.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- 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.
- 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.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Preparing the site
- Tell us which areas need to stay in use
- Have the specification and drawings to hand

Keeping the joints sound
After handover, these steps help:
- Inspect exposed joints once the cold weather has passed
- Note which joints were done, when, and with what
- Treat a small split as a warning, not a cosmetic issue
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load and the reseal becomes an edge repair as well. A sound seal keeps the joint working.

Pin Green: questions and answers
Can you work at a site such as Monkswood Retail Park, by Pin Green?
Yes. Estates, retail parks and business parks around Pin Green, Monkswood Retail Park among them, are all within reach. To start, just call the office on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Is Pin Green too small for you to travel to?
No. Places such as Pin Green 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 seal car park deck joints?
Yes. Tell us how the car park is used and which areas must stay open and we’ll plan around them.
What timescale should we allow for resealing expansion joints?
It normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Timings are set out in the quote along with the phasing plan.
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.
Can you work while the building is occupied?
Typically, yes. We phase the work so most of the building stays in use.
Which product is best for expansion joints?
It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints, and the specification has the final say.
