About our commercial sealant contractors in Wandsworth
Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey. Anything suspect is left alone until it has been tested. If you have untidy joints in a reception, shop floor or lobby and layers of sealant, all of them failing, we can put it right, on external facade joints, floor and threshold joints and window and door perimeters alike. For commercial sealant work in Wandsworth, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In an occupied building in Wandsworth, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.
Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.
A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, phone 01277 525 020 or send photos by email and we will come back to it.

Different surfaces, different methods
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, room by room if that suits the building.
Window and door perimeters
Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. The product depends on whether the joint will be painted.
Cost factors for sealant joints
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- The product specified
- Whether the work must be split into stages
- How much there is to seal
- The size and state of each joint
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
Details that help us quote
We can often quote from photographs and a few details. It helps to include:
- The product your specification calls for
- The asbestos register, for older buildings
- What the building is and how it’s used
- Anything awkward about access or site hours
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Common questions from Wandsworth clients
Does a hotel in Wandsworth need to shut while its sealant is renewed?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What about asbestos in old mastic?
It can, on some older buildings. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can you take on work for an FM or managing agent?
Yes. You send the details, we return a fixed quote, and the job is done and signed off.
Does commercial sealant work come with a guarantee?
A 12-month guarantee covers the workmanship, starting at sign-off. Keeping joints clean and inspected helps them last well beyond that.
Commercial sealant contractors in Wandsworth: the local picture
London premises usually come with a building manager, booked loading and house rules for contractors. We plan around them and agree phasing so tenants and customers aren’t disrupted. A good number of hotels sit less than 2 miles from Wandsworth. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet, and the work can be phased so the rest of the hotel keeps trading.
In hotels such as The Alma Hotel, less than half a mile north-east of Wandsworth, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Offices and shops close to stations such as Wandsworth Town station (less than half a mile north-east of Wandsworth) tend to be busy all day, so sealant work is planned around opening hours. If you have premises on more than one site, say at Chartwell Business Park and Hurlingham Business Park, one contractor and one quote can cover both.
Wandsworth is about 3 miles south-west of Brompton, in Greater London. Across the SW18 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Wandsworth is one of 764 places we cover in Greater London for sealant joints.
Commercial sites across SW18, SW15 and SW11 are covered. Among the streets we cover are Alma Road, Marl Road and Knoll Road, and sites on any of them can send details for a fixed quote. Just outside Wandsworth, we also work in Southfields (1 mile south), Earlsfield (1 mile south), Hurlingham (1 mile north), Clapham Junction (1 mile north-east) and Battersea (1 mile north-east). Bigger towns within reach include London (5 miles north-east), City of Westminster (4 miles north), Marylebone (5 miles north-east), Kensington (3 miles north), St Pancras (6 miles north-east) and Shoreditch (7 miles north-east).
Local landmarks in Wandsworth
We work on buildings around Ashcroft Technology Academy, Emanuel School and Spread Eagle pub, among other places. There’s a railway station in Wandsworth itself: Wandsworth Town station. Well-known places in the area include Southside Wandsworth (under half a mile west) and Antique Breadboard Museum (1.4 miles north-west). Open spaces near Wandsworth include Battersea Park Lake and Henman Hill.
Leave it or put it right?
Spot repairs have their place. Where the remaining sealant is just as old, it tends to fail soon after. We can price both options so you can decide on the facts. Failed sealant in a building in Wandsworth can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Suspect materials that need testing and specialist removal
- Faulty windows rather than failed perimeter sealant
- A failed roof covering or waterproofing membrane
Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly.
Where we work in Wandsworth
- External facade joints
- Movement joints in walls and floors
- Kitchen worktops and splashbacks
- Window and door perimeters
- Washrooms and tea points
- Floor and threshold joints
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
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 easy to get wrong without experience.
Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. In Wandsworth, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First, details come to us: photographs, drawings or a schedule of the areas.
- Next comes a diagnosis and a fixed quote.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- We strip the failed bead and prepare both faces of the joint.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
What we need from you
- Point out parking and an unloading spot
- Flag any permit to work we’ll need
- Let building users know which areas are affected
