About our expansion joint sealing in Keynor Estate
Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. We work on brickwork movement joints, precast concrete panel joints and podiums and floor movement joints, and what we’re called in for most is expansion joints filled with dirt and stones and expansion joints split through the centre of the bead. Whoever orders the work in Keynor Estate, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places such as Keynor Estate, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

When to call us in Keynor Estate
When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.
Common reasons buildings call us in:
- Torn sealant in brick or block movement joints
- Water dripping through deck or ramp joints
- Weathered movement joint sealant that no longer flexes
- Sealant peeling off one face of the joint
On a site such as Enborne Business Park (0.5 miles south-east of Keynor Estate), the movement joints are in car park slabs, paving and building elevations.

What else we do in Keynor Estate
Why act early in Keynor Estate
Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Older rural buildings around Keynor Estate move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Joints that move: notes for Keynor Estate
With the shore within about 1 mile, Keynor Estate counts as a coastal location. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. Keynor Estate sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.
A healthcare site such as St Richard's Hospital, 5.2 miles to the north of Keynor Estate, depends on car parks, ramps and service yards whose joints take traffic all day. University campuses such as University of Chichester (to the north-east of Keynor Estate) have car parks, paved walkways and building elevations with movement joints.
Keynor Estate is about 2 miles north of Selsey, in West Sussex. We cover Keynor Estate, with the same fixed quotes and 12-month guarantee as everywhere else. Our West Sussex coverage takes in 373 places. Sites around Portsmouth have their own page, roughly 13 miles from Keynor Estate.

Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
How the quote is worked out
We price every job individually. The main factors are:
- Quantities, in metres or numbers
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
Whether it’s one area or a whole building, the same details help:
- When you need the work done
- Anything awkward about access or site hours
- Drawings or a marked-up plan, if available
- Where the site is, with the postcode
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email a schedule or drawings.
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.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Common questions from Keynor Estate clients
Can you work on a hospital site such as St Richard's Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Does the sea air around Keynor Estate change the choice of sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you use silicone or polyurethane in movement joints?
We choose a sealant with a movement capability that suits the joint. Where two different materials meet, a hybrid sealant can be the better choice.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
How do you choose the sealant?
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.
