Sealant applicators in Cooper's Green
Most of the buildings we seal stay open while we are there. Tell us your site hours and access windows and we will plan around them. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. We work on window and door perimeters, movement joints in walls and floors and washrooms and tea points, and the usual reasons a site gets in touch are movement joints packed with grit and debris and water staining near frames, panels or ceilings. Most enquiries from Cooper's Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Occupied buildings in Cooper's Green need the work phased: washrooms in turn, floors in sections and entrances kept open.
Rural business units near smaller places such as Cooper's Green are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Add sealant to the planned maintenance inspection list
- Ask fit-out and M&E contractors to report any sealant they disturb
- Brief cleaning contractors to avoid scourers and blades on sealant
- Act on the first lifting edges rather than waiting
Keep an eye out for other trades after we’ve gone. Shop refits, new services and replaced fittings often break the seal around them and the joint gets left open. If that happens, ring 01277 525 020 or use the quote form and we’ll price putting it right.
Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.
Leave it or put it right?
A cheaper quote sometimes means the old bead stays in. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation. Halls, stores and units around places like Cooper's Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
How the quote is worked out
A fixed quote reflects the actual work. It allows for:
- Whether the work must be split into stages
- Induction, permit and paperwork requirements
- Any access equipment needed
- Location, for remote and island sites
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
Sending details for a quote
A few photos plus some basic facts will normally do. It helps to include:
- Clear photographs of the problem areas
- The asbestos register, for older buildings
- When you need the work done
- Whether the building will be occupied during the work
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or email the details over.

Questions about Cooper's Green
Will you take on work at estates like Oldings Corner Retail Park, close to Cooper's Green?
Yes, sites like Oldings Corner Retail Park are within our area, along with the rest of Cooper's Green. Send details of the unit and the work through our quote form for a quick quote.
Is Cooper's Green off your patch?
Not at all. Cooper's Green is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.
Is failed sealant stripped out, or sealed over?
Every scrap of failed sealant is removed before the new bead goes on. Sealing over traps water and lifts once the joint moves and isn’t worth paying for.
Can one contractor look after sealant on all our buildings?
Yes, we can. Send a list of addresses and what’s needed at each, and fixed prices follow, with a suggested sequence.
Is your work guaranteed?
Our workmanship is guaranteed for 12 months. Public liability insurance is in place too.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Our process
Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. If others near Cooper's Green need work, visits can be combined. You’ll have a fixed quote before work starts.
- You send photographs, drawings or a list of the joints and areas involved.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- 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.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Before we start on site
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work
- Move anything stored against the joints

Advice
Surface 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.
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead.
