About commercial sealant contractors in SE13
If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in SE13, the quickest start is to ring 01277 525 020 or send photos by email with a list of addresses. We work on window and door perimeters, washrooms and tea points and floor and threshold joints, and the failures we’re asked to look at most are black mould through washroom sealant that won’t clean off and window and door perimeter joints that have cracked open.
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- Completed areas are signed off with you under our 12-month guarantee.
What affects the price in SE13
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Near you in St Johns
Around St Johns, our work takes us to commercial buildings near Brookmill Park, Church of St John and Wickham Arms. Also close by are St. Paul's (0.7 miles north), Addey and Stanhope School (under half a mile north-west), Ashmead Primary School (less than half a mile west) and Laban Centre (0.8 miles north). There’s a railway station in St Johns itself: St Johns station. Well-known places in the area include Fan Museum (0.9 miles north-east) and Lewisham Shopping Centre (0.7 miles south-east). Not far away are Brookmill Road Local Nature Reserve and Tower Hill.
Shops, offices and hotels in SE13
From St Johns, Lewisham and Hither Green outwards, SE13 has a broad spread of commercial premises: shops, offices, hotels, restaurants and units. We cover the whole area, so occupiers with several sites can use one contractor and one point of contact.
London and the South East are among the drier parts of the UK, though outside work in SE13 still waits for dry faces, and cold mornings bring frost and condensation on steel and glass.
St Johns: Shops and cafés around stations like St Johns station (less than half a mile south of St Johns) trade from early, so work is timed around them. Units at places like Lewisham Shopping Centre (0.7 miles south-east of St Johns) are refitted as brands change, and the joints have to suit each new scheme.
What we are called out for in SE13
Plenty of failed joints were never sealed with the right product. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade will all fail early. BS 6213 gives guidance on choosing construction sealants.
If one of these sounds familiar, it’s time for a closer look:
- Damp patches where an external joint has failed
- Movement joints packed with grit and debris
- Mouldy silicone around WCs, urinals and vanity tops
- External beads that have gone brittle and cracked
Surface by surface
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead, planned so the building keeps enough facilities in use.
Fire-rated seals where specified
Not every penetration suits a sealant. Other products, such as collars, wraps and batts, are specified for different services, so we’ll flag it if the detail needs a different product.
Commercial clients in SE13
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Don’t let cleaning or traffic back on before the cure time is up
- Check sealant as part of routine building inspections
- Keep washroom and kitchen extraction working
- Keep abrasive pads and scrapers off resealed joints
Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just call the office on 01277 525 020 or use the quote form for a quote.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are.
SE13: questions and answers
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What about asbestos in old mastic?
Some older mastics did contain asbestos. 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.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators.
Is it OK to apply fresh sealant over existing beads?
Full removal is part of every quote. Sealing over traps water and lifts once the joint moves.
Do you work directly for building managers?
Yes. A large share of our work comes through facilities managers, managing agents and landlords, alongside main contractors. Tell us how you issue work and we’ll fit in.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do you cover SE13?
Yes. We cover SE13, and you can phone 01277 525 020 or use the quote form to get started.
