Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Faulty windows rather than failed perimeter sealant
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
If you are not sure, just phone 01277 525 020 or email us and we’ll give you a straight answer.
What we seal
- Window and door perimeters
- Washrooms and tea points
- External facade joints
- Movement joints in walls and floors
- Floor and threshold joints
- Kitchen worktops and splashbacks
Sealant specialists in Copse Hill
If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Copse Hill, ring 01277 525 020 or email a schedule or drawings with the site addresses. The enquiries we see most involve a top-up bead over failed sealant, now lifting and smeared sealant across finishes from a rushed job, across kitchen worktops and splashbacks, floor and threshold joints and washrooms and tea points. A specialist sealant contractor works differently from a general builder: on jobs in Copse Hill, preparation and product choice get the time they need.
On a typical commercial building in Copse Hill, the joints that fail first are the hardest-worked ones: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. The right product goes on each, in a colour chosen to suit where the joint is seen.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

When to call us in Copse Hill
The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade. BS 6213 gives guidance on choosing construction sealants.
Look out for the following:
- Movement joints packed with grit and debris
- Mouldy silicone around WCs, urinals and vanity tops
- Frame sealant that has cracked, shrunk or pulled away
- Earlier reseals applied straight onto the failed bead
Units at places like Priory Retail Park (to the east of Copse Hill) are refitted as brands change, and the joints have to suit each new scheme.
Before you book anyone
- How long is the guarantee, and what does it include?
- Their approach to joint depth and backing
- How the joint faces will be prepared and primed
- Whether old or failed sealant will be cut out, not overlaid

Questions about Copse Hill
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.
Can you work at a site such as Rainbow Industrial Estate, by Copse Hill?
Yes. We cover Copse Hill and the area around it, including industrial estates, business parks and retail parks such as Rainbow Industrial Estate. Photos and a short description are enough for a first look.
Do you check for asbestos before removing sealant?
It’s possible in older buildings, especially those built before 2000. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
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 products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards.

Why it’s worth doing now in Copse Hill
Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but a joint letting water in now keeps doing damage until the refurb arrives. We can seal the urgent joints now and leave the rest for the programme. Getting scaffold, permits or access booked in Copse Hill takes effort, so it makes sense to deal with every failing joint while access is in place.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Take a look at how commercial sealant jobs are priced and how we’re accredited.
Surface by surface
Movement joints in walls and floors
Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. Failed seals let grit and water in, and the edges start to suffer. The new sealant is chosen for the movement and, on floors, the traffic.
Shop fronts and retail fit-outs
Retail work typically has to fit around trading. Tell us your trading hours and access windows and we’ll plan around them.
On site: what to expect
Inspect, seal, 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. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

- We agree the order of work, access windows and site hours with you.
