For managing agents and facilities managers
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Facade sealing in Balham
Facade sealants sit in the sun, rain and frost every day, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. If you’re dealing with new sealant peeling off old mastic and gaps between rainscreen or cladding panels, we can help, whatever the surface. Looking for mastic applicators who cover Balham? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Construction in a London area such as Balham means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Mastic packages on Balham sites
Balham has plenty of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Balham. Deliveries are booked and storage is tight, so mastic materials come in as needed.
For contractors on a campus like University of the Arts London, which lies north of Balham, facade and perimeter sealing has to fit around students and term dates. On a healthcare site such as Springfield University Hospital, 0.9 miles south-west of Balham, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Hotels like Gateway Hotel (0.6 miles north of Balham) rarely close for long, so refurbishment mastic is phased floor by floor.
Balham is about 2 miles south-west of Stockwell, in Greater London. Balham sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Across Greater London, 764 places are covered, including Balham.

FAQs: Balham
Do you take on jobs in Balham where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Do you cover business parks and estates near Balham, such as Zennor Road Industrial Estate?
Yes. Our area takes in Balham and its surroundings, with estates and business parks such as Zennor Road Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you work in cold or wet weather?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start, and we build that into the programme.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

From enquiry to sign-off
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. All of Greater London is in the ULEZ, and kerbside space in Balham can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work
- Agree which areas must stay open

Related advice
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Whether the work must be split into stages
- How accessible the joints are
- Whether old sealant has to be cut out first
- The total length or number of joints
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Clear photos of the problem areas
- Access details, including height
- Approximate linear metres or a joint schedule
- Any specification or named product

Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Water getting in through cracked render or porous masonry
- Damaged frames that need replacing
- Providing access systems for the work
Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
Surfaces we seal
- Coping and flashing joints
- Perimeter joints where frames meet the structure
- Stone and brick facade joints
- Window and door perimeters
- Cladding panel joints
- Shopfront frames
Different surfaces, different methods
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, with masked edges for a clean line.
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Note when each elevation was last resealed
- Keep pressure washers away from fresh sealant
- Plan facade sealing alongside redecoration
- Add perimeter sealant to planned maintenance checks
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.
