Our commercial sealant contractors service in SE23
We’ve applied sealant on commercial sites for over 20 years, and the paperwork side is in order: we’re CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. The enquiries we see most involve frame mastic that has hardened and come away from the wall and greasy, split joints in a kitchen or tea point, across kitchen worktops and splashbacks, external facade joints and movement joints in walls and floors.
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly.
- First, details come to us: photographs, drawings or a schedule of the areas, or we arrange a site visit.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Finished joints are checked with you and handed over with our 12-month guarantee.

Around Perry Vale
Around Perry Vale, our work takes us to commercial buildings near Mayow Park, Christ Church and Allenby Tutorial Trust and the streets around them. Also close by are Perrymount Primary School (under half a mile north-west), Capitol Cinema pub (0.6 miles north-west) and Forest Hill School (under half a mile south-west). The nearest railway station is Forest Hill station, roughly 0.5 miles north-west of the centre. Nearby you will also find Lewisham Shopping Centre (2.3 miles north-east) and Greenwich Castle (3.5 miles north-east). The countryside around Perry Vale includes Dacres Wood and Knight's Hill.
Commercial premises across SE23
From Sydenham, Perry Vale and Crofton Park outwards, SE23 has a broad spread of commercial premises: shops, offices, hotels, restaurants and units. Because we cover all of it, multi-site occupiers can bring every building under one quote, with colours matched site to site where the brand needs it.
The South East is one of the UK’s drier regions, but external sealing in SE23 still needs a dry joint and the right temperature, and damp or frosty mornings can hold it up.
Perry Vale: In hotels such as Astra Palace Hotel (1.4 miles south-west of Perry Vale), refurbishments normally 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 Forest Hill station (0.5 miles north-west of Perry Vale) tend to be busy all day, so sealant work is planned around opening hours.
Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Walls or slabs moving more than any sealant can take
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Leaks from pipework, wastes or valves (that’s plumbing)
Why act early?
Leaving a failed joint rarely saves money. Once water gets behind the seal, finishes and ceilings underneath are next. Resealing while only the sealant has failed keeps the job small.
What your quote should include
- Which product they’ll use, and why it suits the joint
- Whether primer will be used where the manufacturer specifies it
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How they’ll work around occupants
Signs you need commercial sealant contractors
In wet areas the enemy is normally mould rather than movement. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant. The fix is a new bead of anti-mould sanitary silicone.
Typical triggers for a call:
- Damp patches where an external joint has failed
- Shrunken sealant along kitchen worktops and splashbacks
- Mouldy silicone around WCs, urinals and vanity tops
- Layers of sealant, all of them failing
After the work
To get the most from the new sealant:
- Make sure ventilation in wet areas is switched on and working
- Ask fit-out and M&E contractors to report any sealant they disturb
- Check sealant as part of routine building inspections
- Deal with small splits before they become leaks
We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.
Sealant installed at the same time usually fails in sequence. A few splits this year typically mean more next year, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.
How the job changes by surface
Facade and cladding joints
Panel joints on cladding and rendered facades open and close with the temperature. They need a sealant with the right movement capability, laid at the right depth. We confirm the access in place before we quote.
Shop fronts and retail fit-outs
In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line. We will confirm the colours available for the specified product.
Your questions answered
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators.
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.
Can areas stay open during the work?
Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.
Do you work directly for building managers?
Yes. FMs, managing agents and landlords are among our regular clients, alongside main contractors. We can work to your instruction process and site rules.
What do you need from us to quote?
Start with whatever information is to hand. Questions or a site visit follow where needed, then a fixed quote.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Do you cover SE23?
Yes. We take on work across SE23, with one number for every area we cover.
