How we handle expansion joint sealing in Gunville
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. If you have layers of sealant in a movement joint and water getting into the wall through a failed joint, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Gunville is the same: the right product in a properly prepared joint.
Around smaller places such as Gunville, 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 we finish is backed by a 12-month workmanship guarantee, in Gunville as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Slabs, ramps and loading bays in Gunville
Gunville is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open. At least three named trading, business or retail sites lie within about 3 miles of Gunville. Their warehouses, yards and car parks are exactly where joints take the most punishment.
In a school such as Carisbrooke College, movement joints in brick, block and hall floors tend to be forgotten until they leak. Phasing is what makes joint work possible on busy sites such as Mountjoy Industrial Estate (1 mile south-east of Gunville): one bay, aisle or car park row at a time. For an estate such as Laidlaw Day Hospital, which lies north-east of Gunville, the joints in ramps, decks and long building elevations all need attention over time.
Gunville is about 1 mile west of Newport, in the Isle of Wight. Anywhere in PO30, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 125 places across the Isle of Wight fall within our area, Gunville among them. Sites around Portsmouth have their own page, about 13 miles away.

General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Movement on a scale no sealant is meant to absorb
- Leaks coming from the membrane rather than the joint seal
- Broken or spalled joint edges, which need repairing before any sealant goes in
Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Common questions from Gunville clients
Does your area include sites such as Carisbrooke Retail Park, near Gunville?
Yes. We cover Gunville and the area around it, including industrial estates, business parks and retail parks such as Carisbrooke Retail Park. Photos and a short description are enough for a first look.
Would you work within a site like Laidlaw Day 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.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Who decides which product is used?
The specification comes first, if there is one. 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 long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. For work around Gunville, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Before we start on site
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
- Tell us which areas need to stay in use

Why act early in Gunville
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach, and we will say so before quoting. One visit to deal with every failing joint makes more sense than several trips to a place like Gunville. Photos of every joint help us quote for the whole job.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
