What sealant work can’t fix
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Changing the joint layout or spacing of a structure
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Questions about Newport
Can you work at a site such as Towngate Retail Park, by Newport?
Yes. We cover Newport and the area around it, including industrial estates, business parks and retail parks such as Towngate Retail Park. A few photos and the unit address let us price the work.
Must our site in Newport stop work while the joints are done?
Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.
What site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.
Joints that move: notes for Newport
Newport has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint.
A healthcare site such as Laidlaw Day Hospital, 0.7 miles to the north of Newport, depends on car parks, ramps and service yards whose joints take traffic all day. For a school such as Nine Acres Primary School, playground and building joints can be done in the holidays.
Newport is about 10 miles south-west of Gosport, in the Isle of Wight. Anywhere in PO30, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across the Isle of Wight, 125 places are covered, including Newport. We also cover Portsmouth, around 12 miles from Newport.
Postcode districts covered here: PO30 for movement joints. If your site is on High Street, Red Fox Square and Drill Hall Road or close by, send details and we’ll quote for movement joints. Access to Newport is via the A3020 and A3054, so getting applicators and materials to site is simple. If your building is just outside Newport, we cover Shide (1 mile south-east), Blackwater (2 miles south), Downend (2 miles east), Merstone (3 miles south-east) and Rookley (3 miles south). Further afield, our area takes in Ryde (6 miles east), Cowes (4 miles north), Sandown (7 miles south-east), Shanklin (7 miles south-east), Ventnor (8 miles south-east) and East Cowes (4 miles north). Newport is one of the busier places in the Isle of Wight, and we take on movement joints for its commercial and public buildings. For island and remote sites, travel and materials need planning ahead.
Local landmarks in Newport
Recent enquiries here include premises near Seaclose Park, Castle Inn and Christ The King College. Nearby you’ll also find Carisbrooke Castle (1 mile south-west) and St Mary's Hospital (0.8 miles north). For a walk, there’s Briddlesford Nature Reserve and Mill Hill.
How a job runs
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most work in Newport is one building at a time: a school, a unit, an office or a block. Your photographs, drawings or a site visit come first, followed by a fixed quote.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- 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.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready
- Tell us what induction or permit system the site runs
- Send your site hours and access windows
- Point out any areas we must not close
Ask for a quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

What the job involves on each surface
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces priming where the maker calls for it.
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors, with a flexible sealant where movement is larger.
What we’re called out for in Newport
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way, so we check width and movement before quoting.
These are often picked up first by site or facilities staff:
- Movement joints with split or torn sealant
- Water dripping through deck or ramp joints
- Sealant peeling off one face of the joint
- Expansion joints filled with dirt and stones
Another example is Wakes Retail Park (0.5 miles north-east of Newport), where floors and yards would be done in stages around the occupiers.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- What level of public liability insurance do they hold?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
Leave it or put it right?
Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too, and a second visit means paying for access again. Where it helps, we quote both options. In a town like Newport, a split, stained or mouldy joint is often the first thing visitors notice. Fresh sealant makes a building look maintained.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
