How the job changes by surface
Render and coated surfaces
Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone.
How we handle facade sealing in Wandsworth
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. Most enquiries involve weathered joints at frame-to-structure perimeters and water coming in around window frames, on shopfront frames, window and door perimeters and cladding panel joints. Searching for sealant specialists in Wandsworth? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around Wandsworth, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or email drawings and photos and we’ll come back to it.

Sites and facades in and around Wandsworth
A 2-mile radius around Wandsworth takes in plenty of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. As part of Greater London, Wandsworth is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in.
Further education sites such as South Thames College Wandsworth Campus, less than half a mile to the north-east of Wandsworth, are extended and refurbished from time to time, with mastic often programmed into the summer break. University estates such as BIMM University (to the north of Wandsworth) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
Wandsworth is about 3 miles south-west of Brompton, in Greater London. Businesses, contractors and managing agents in Wandsworth use us for work on facade joints, as part of our coverage of Greater London. Wandsworth is one of 764 places in Greater London on our list for facade joints.

Cost factors for facade joints
To price the job, we consider:
- Distance, for remote addresses
- Phasing around occupants
- Induction, permit and paperwork requirements
- Backing rod, priming and other preparation
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- The site address and postcode
- Whether the building will be occupied during the work
- Rough lengths or quantities, or drawings if you have them
- How the joints are reached, and at what height
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Common questions from Wandsworth clients
Can you work at a site such as Chartwell Business Park, by Wandsworth?
Yes. Estates, retail parks and business parks around Wandsworth, Chartwell Business Park among them, are all within reach. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
Do you provide access for facade work?
That comes down to the access arranged for the job. When you call the office on 01277 525 020 or email the details over, describe the access, and we will plan the work with you.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited and a Constructionline member.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Specialist high-level access methods
- Replacing glass or failed glazing units
- Damaged frames that need replacing
Not sure which it is? You can phone 01277 525 020 or email the details over and we will tell you honestly before you book.
Surfaces we seal
- Shopfront frames
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Stone and brick facade joints
- Window and door perimeters
- Coping and flashing joints
Do you need facade sealing in Wandsworth?
Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back.
Site and facilities staff are often the first to spot these:
- Staining on stone next to old sealant
- Perimeter sealant that has split or peeled away
- Gaps between rainscreen or cladding panels
- Cold air coming in at window perimeters
On a healthcare site such as Royal Hospital for Neuro-Disability, which lies west of Wandsworth, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What your quote should include
- Whether their applicators hold CSCS cards
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their pre-qualification and accreditations
- Whether old or failed sealant will be cut out, not overlaid
On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. 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.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
- Tell us which areas need to stay in use
