About commercial sealant contractors in SE27
We’ve applied sealant on commercial sites for over 20 years, and the paperwork side is in order: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. Site teams most often ask us about earlier reseals applied straight onto the failed bead and external beads that have gone brittle and cracked, across external facade joints, washrooms and tea points and kitchen worktops and splashbacks.
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
How we quote

Shops, offices and hotels in SE27
The commercial stock in SE27 mixes older town-centre buildings with newer offices and units, in places such as West Norwood, Upper Norwood and Norwood New Town and beyond. Surfaces decide the sealant, from masonry to powder-coated frames and shop-fit panels.
We work across Greater London and the South East counties, so jobs in SE27 are planned with access, loading and parking in mind.
West Norwood: Occupiers with premises at both Hamilton Road Industrial Estate and Parkhall Business Centre could have the sealant at each handled under one quote. A hotel such as Astra Palace Hotel (0.9 miles east of West Norwood) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.
Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- A failed roof covering or waterproofing membrane
- Suspect materials that need testing and specialist removal
- Faulty windows rather than failed perimeter sealant
What we are called out for in SE27
Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. On a busy commercial site several of those pile up at once, which is why regular inspection pays.
Look out for the following:
- Earlier reseals applied straight onto the failed bead
- Messy, uneven beads from earlier work that let the building down
- External beads that have gone brittle and cracked
- Wall and floor joints that have lost their seal
Surface by surface
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services and gaps, so we’ll flag it if the detail needs a different product.
Shop fronts and retail fit-outs
Retail work typically has to fit around trading. We plan around the access windows the store gives us, phasing areas so the shop floor stays usable.
How the quote is worked out
To price the job, we consider:
- Joint width, depth and condition
- Working within restricted access windows
- How much there is to seal
- How accessible the joints are
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 we need to price the job
A few photos plus some basic facts will normally do. Please tell us:
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
- Clear photos of the problem areas
- The postcode of the building
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Questions about SE27
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Can you supply RAMS and insurance details?
We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Our applicators are CSCS-carded.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Is SE27 in your area?
Yes. We take on work across SE27, with one number for every area we cover.
What about asbestos in old mastic?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.
How do you keep disruption to occupiers down?
That comes down to planning: we agree access windows, phase the work and keep enough facilities open. Let us know what can’t close and we’ll work around it.
