Commercial mastic work in Chatham Green
Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed. Anything suspect is left alone until it has been tested (removing asbestos-containing materials isn’t something we do). We work on floor and threshold joints, external facade joints and movement joints in walls and floors, and the usual reasons a site gets in touch are sanitary sealant that has gone black and patchy and greasy, split joints in a kitchen or tea point. Most enquiries from Chatham Green start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Multi-site clients with buildings in and around Chatham Green can put several sites on one programme, so standards and paperwork match across every site.
Business units in the countryside around places like Chatham Green are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Our process
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For work around Chatham Green, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- 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.
Getting the site ready
- Make sure the joints can be reached
- Arrange parking or a loading space
- Tell us which areas need to stay in use

Common questions from Chatham Green clients
Do you offer colour-matched sealant for buildings in Chatham Green?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.
Is a smaller place like Chatham Green outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
What site paperwork can you provide?
We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- A dripping trap, valve or pipe behind a fitting
- A failed roof covering or waterproofing membrane
- Misted, cracked or failed glazing units (a glazier’s job)
If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Window and door perimeters
- External facade joints
- Washrooms and tea points
- Movement joints in walls and floors
- Kitchen worktops and splashbacks
- Floor and threshold joints
Commercial sealant contractors around Chatham Green: how the place shapes the job
The South East is one of the drier parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Two named trading, business or retail sites lie within about 3 miles of Chatham Green. Each new occupier on a park like these tends to refit, from reception to staff kitchen.
Premises within reach of Beaulieu Park station, 4.1 miles to the south of Chatham Green, often have busy frontages where joints are seen by everyone passing. If you run an office at a site such as Banters Lane Business Park, 1.8 miles north-east of Chatham Green, the sealant at reception desks, tea points and frames ages with each fit-out. Sites a few miles apart, such as Banters Lane Business Park and Regiment Business Park, can share one programme and one point of contact.
Chatham Green is about 5 miles north of Chelmsford, in Essex. We cover Chatham Green, with the same fixed quotes and 12-month guarantee as everywhere else. Our Essex coverage takes in 644 places, large and small. Sites around London have their own page, about 33 miles away.

Aftercare for building managers
For the best life from the joints:
- Keep washroom and kitchen extraction working
- Keep barriers up until the new sealant has cured
- Ask fit-out and M&E contractors to report any sealant they disturb
- Act on the first lifting edges rather than waiting
Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, with external elevations and wet areas first in line. If anything looks wrong, call 01277 525 020 or send details through our quote form with a photo.
Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.
When to bring in a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
What happens if it’s left?
Some managers wait for a fit-out before touching the mastic. That’s reasonable for internal joints that are just tired-looking, 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. One visit to deal with every failing joint makes more sense than several trips to a place like Chatham Green, rather than one at a time. Photos of every joint help us quote for the whole job.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you are ready.
