Commercial sealant contractors in Cotman's Ash, done properly
Getting a price for commercial sealant contractors in Cotman's Ash doesn’t need to be drawn out. Send photos, drawings or a schedule of the joints through our quote form; you can also call the office on 01277 525 020 or send photos by email with the details. Where the photographs don’t tell the full story, we arrange a site visit, followed by a fixed quote rather than an estimate that drifts. We work on movement joints in walls and floors, kitchen worktops and splashbacks and washrooms and tea points, and what we are called in for most is damp patches where an external joint has failed and window and door perimeter joints that have cracked open. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Cotman's Ash it comes down to the same thing: the right product in a properly prepared joint.
Occupied buildings in Cotman's Ash need the work phased: washrooms in turn, floors in sections and entrances kept open.
Business units in the countryside around places like Cotman's Ash are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Check joints after other trades have worked nearby
- Keep abrasive pads and scrapers off resealed joints
- Put external and wet-area joints on a regular inspection round
- Don’t let cleaning or traffic back on before the cure time is up
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.
Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.

Your questions answered
Is Cotman's Ash too small for you to travel to?
Not at all. Cotman's Ash is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can the sealant on our Cotman's Ash premises match the finishes?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.
How do we get a quote?
The main factors are metres of joint, removal, access, the product and how many phases there are. To get a fixed price, send details through our quote form, or phone or email us.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What about asbestos in old mastic?
It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.
What guarantee do you give on resealing?
Each job sits under our 12-month guarantee from handover. Looking after the joints as we advise helps them last.
How many days will you need on site?
It depends on the scope, though a typical visit usually takes a few hours for one area, or a planned series of visits across a bigger building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
What Cotman's Ash’s businesses ask us to seal
Cotman's Ash has at least three named business or industrial parks inside a 3-mile radius. Each new occupier on a park like these tends to refit, from reception to staff kitchen, often in a colour the occupier specifies. At about 19 miles from central London, Cotman's Ash is within reach of the capital. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site.
A business with units at Chaucer Business Park and West Kingsdown Industrial Estate needn’t use two contractors for its sealant. For premises near Kemsing station, 1.4 miles south of Cotman's Ash, footfall is part of the plan: work is phased so shops and offices keep trading. Offices at parks like Chaucer Business Park, 1.3 miles south of Cotman's Ash, have receptions, kitchens and glazed partitions where a tidy joint matters.

How a job runs
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Cotman's Ash are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First, details reach us through the quote form or a site visit.
- We diagnose the cause of failure and price a fixed scope.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.

What affects the price in Cotman's Ash
What shapes the price:
- Induction, permit and paperwork requirements
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- Working within restricted access windows
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
Before you send an enquiry
Whether it’s one area or a whole building, the same details help:
- Any dates the work must fit around
- The asbestos register, for older buildings
- Any specification or named product
- The site address and postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
What the job involves on each 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 joints are resealed using a sealant matched to the movement and any traffic.
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t, matched to the frame colour where colour matters.
Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Broken glass or blown double-glazed units
- Cracking that needs a structural engineer to look at it
- Suspect materials that need testing and specialist removal
If in doubt, call 01277 525 020 or email us and we will say what we think before you book.
