Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Keep barriers up until the new sealant has cured
- Deal with small splits before they become leaks
- Keep washroom and kitchen extraction working
- Look at the sealant around anything that has been moved or replaced
Add the resealed joints to your planned maintenance inspections. Regular checks pick up small failures before they become leaks, with external elevations and wet areas first in line. Should something look amiss, you can phone 01277 525 020 or send details through our quote form and send a picture.
Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.
Commercial mastic work in Northney
Commercial occupiers rarely want a floor out of action for sealant work. Tell us your site hours and access windows and we will plan around them. That applies whether the building is an office, a shop, a hotel, a college or a care home. We work on window and door perimeters, kitchen worktops and splashbacks and movement joints in walls and floors, and the usual reasons a site gets in touch are sanitary sealant that has gone black and patchy and movement joints packed with grit and debris. One point of contact handles commercial sealant work in Northney from the first photographs to the final walk-round, whether it’s one building or several.
A lot of what we do in Northney is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.
Rural business units near smaller places such as Northney are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Doing it in-house
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
FAQs: Northney
Is Northney off your patch?
Not at all. Northney is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Our building in Northney is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
How is commercial sealant work priced?
Send what you have, even a few photographs and rough lengths. We follow up with questions or a visit where needed, then a fixed quote.
Can one contractor look after sealant on all our buildings?
Yes, across South East England, Greater London and all of Scotland. Each site gets the same process and a single contact.
Can you take on work for an FM or managing agent?
Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
Are you CHAS accredited?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes a few hours to several days on most single sites, depending on joint lengths and access, and we clear our waste as we work. Jobs in and around smaller places like Northney are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First, details come to us: photos, drawings or a schedule of the areas.
- Next comes a diagnosis and a fixed quote.
- Site hours, access windows and the order of areas are agreed before we start.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
Before we start on site
- Share your working hours and any access restrictions
- For older buildings, check the asbestos register before work
- Point out parking and an unloading spot
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
When something else is needed
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- A dripping trap, valve or pipe behind a fitting
- Structural cracks or movement the joints weren’t designed for
- Roof leaks that only look like a joint problem
If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think before you book.
What we seal
- External facade joints
- Floor and threshold joints
- Washrooms and tea points
- Kitchen worktops and splashbacks
- Movement joints in walls and floors
- Window and door perimeters
Surface by surface
Fire-rated seals where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps, so we will flag it if the detail needs a different product.
Washrooms and toilets
Mould that has grown into washroom sealant can’t typically be cleaned out. Replacement is the fix: strip, clean, dry and reseal, planned so the building keeps enough facilities in use.

What Northney’s businesses ask us to seal
The sea is no more than about 1 mile from Northney. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Sea-facing elevations are usually where failed joints show first. Rainfall across the South East, Northney included, is lower than in many parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it.
Refits at hotels like Ropemaker Hotel (to the north of Northney) bring joints at vanity tops, bars and reception desks that guests see every day. A unit on an estate like Finchwood Farm Industrial Estate (1 mile south of Northney) typically has an office front, a trade counter and staff facilities with joints of their own. If you have premises on more than one site, say at Finchwood Farm Industrial Estate and Solent Retail Park, one contractor and one quote can cover both.

What sets the cost
We price every job individually. The things that drive the figure:
- How much existing material needs removing
- Phasing around occupants
- Access and working height
- Location, for remote and island sites
Access can matter as much as the joints themselves: 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 to include in your enquiry
A few photos plus some basic facts will normally do. Please tell us:
- Any specification or named product
- The asbestos register, for older buildings
- Clear photographs of the problem areas
- The site address and postcode
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call 01277 525 020 or email the details over.
