What sets the cost
The price varies from site to site. Expect it to depend on:
- The site’s rules and procedures
- Phasing around occupants
- Location, for remote and island sites
- Access and working height
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- The site address and postcode
- Whether an asbestos survey exists
- Access details, including height
- The type of building and who uses it
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or use the quote form.
Commercial sealant contractors in Southfields, done properly
A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. We work on washrooms and tea points, window and door perimeters and movement joints in walls and floors, and what we’re called in for most is earlier reseals applied straight onto the failed bead and water staining near frames, panels or ceilings. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Southfields is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
On a typical commercial building in Southfields, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Around Southfields, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. The right product goes on each, in a colour chosen to suit where the joint is seen.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Check the asbestos register before anyone disturbs old sealant in an older building
- Respect the cure time before reopening an area
- Have extract fans checked so wet areas dry out
- Note dates and locations of sealant work for future planning
Give fresh sealant time to cure before it’s cleaned, wetted or walked past. Cure time varies with the product, conditions and depth of the joint, so we confirm it for each area at handover. Keeping signs or barriers up until then protects the finish.
Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.
Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Shops, offices and hotels in and around Southfields
At least three named trading, business or retail sites lie within about 3 miles of Southfields. Each new occupier on a park like these tends to refit, from reception to staff kitchen. In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We work within them, one zone at a time.
If you have premises on more than one site, say at Rufus Business Centre and Garratt Business Park, one contractor and one quote can cover both. For tenants and agents on sites such as Rufus Business Centre, 0.5 miles to the south of Southfields, office fit-outs, reception joints and window perimeters are the usual sealant work.
Southfields is about 2 miles north-east of Wimbledon, in Greater London. We send applicators to Southfields for sealant joints. 764 places across Greater London fall within our area, including Southfields. There’s a separate page for London, roughly 6 miles from Southfields.

We also cover Earlsfield (1 mile south-east), Wandsworth (1 mile north), Summerstown (1 mile south), Battersea (2 miles north-east) and Clapham Junction (2 miles north-east).

FAQs: Southfields
Do you take on jobs in Southfields where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Do hotels near Southfields have to close for sealant work?
In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
Is it OK to apply fresh sealant over existing beads?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can one contractor look after sealant on all our buildings?
Yes. We take on runs of jobs across portfolios as well as single sites, quoted per building or as a package.
What we are called out for in Southfields
Outside, sunlight and rain wear sealant down year after year. UV hardens the surface while wind and rain work at the edges. Once it stiffens, the joint opens up at the next big temperature swing.
Things that typically lead to an enquiry:
- Window and door perimeter joints that have cracked open
- Smeared sealant across finishes from a rushed job
- Shrunken sealant along kitchen worktops and splashbacks
- Weathered facade sealant that no longer flexes
In a retail centre such as Priory Retail Park, 2.2 miles south of Southfields, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.
Questions to ask before you book
- Is the sealant right for the movement and the substrate?
- What site paperwork they can supply
- How they’ll work around occupants
- Do they follow the manufacturer’s priming guidance?
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before we move to the next. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
Preparing the site
- Have the specification and drawings to hand
- Let building users know which areas are affected
- Send your site hours and access windows
