Commercial sealant contractors in Basted, done properly
We’ve applied sealant on commercial sites for over 20 years: 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. We work on external facade joints, movement joints in walls and floors and washrooms and tea points, and the usual reasons a site gets in touch are mouldy silicone around WCs, urinals and vanity tops and gaps behind commercial kitchen worktops and sinks. Looking for mastic applicators who cover Basted? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
A lot of what we do in Basted is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
A job in a smaller place like Basted is normally a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Quoting for work in Basted
Your fixed quote is built from the real scope. It allows for:
- The product specified
- Whether old sealant has to be cut out first
- How accessible the joints are
- Working within restricted access windows
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.
What to include in your enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- The postcode of the building
- The asbestos register, for older buildings
- Access details, including height
- A wide shot and a close-up of the area
To get a fixed quote, give us a call on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Structural cracks or movement the joints weren’t designed for
- Leaks from pipework, wastes or valves (that’s plumbing)
Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly before you book.
What we seal
- Floor and threshold joints
- Window and door perimeters
- External facade joints
- Movement joints in walls and floors
- Kitchen worktops and splashbacks
- Washrooms and tea points
Common problems we fix in Basted
The wrong sealant in the wrong place is a common cause of early failure. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants.
It’s worth sending us details if you spot any of the following:
- Frame sealant that has cracked, shrunk or pulled away
- Earlier reseals applied straight onto the failed bead
- Water staining near frames, panels or ceilings
- Smeared sealant across finishes from a rushed job
Offices at parks like Bourne Enterprise Centre, 1 mile to the north of Basted, have receptions, kitchens and glazed partitions where a tidy joint matters.
Before you book anyone
- Who will actually carry out the work
- Health and safety accreditation such as CHAS
- What level of public liability insurance do they hold?
- Will failed sealant be removed rather than covered?
Frontages, fit-outs and joints in Basted
Rainfall across the South East, Basted included, is lower than in many parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. The 3 miles around Basted take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal.
Premises within reach of Borough Green & Wrotham station, 0.9 miles north of Basted, often have busy frontages where joints are seen by everyone passing. A business with units at Bourne Enterprise Centre and Invicta Business Park needn’t use two contractors for its sealant.
Basted is about 5 miles east of Sevenoaks, in Kent. Businesses, contractors and managing agents in Basted can call on us for sealant joints. We work across 931 places in Kent, from busy centres to rural villages. Our London page has more on work in that area.

Our process

With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If others near Basted need work, visits can be combined. A fixed quote is given before anything starts.
- First, details come to us: photographs, drawings or a schedule of the areas, or we arrange a site visit.
- Next comes a diagnosis and a fixed quote.
- Site hours, access windows and the order of areas are agreed before we start.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
Getting the site ready
- For older buildings, check the asbestos register before work
- Warn occupants and staff about the work
- Arrange parking or a loading space

Questions about Basted
Is Basted off your patch?
Not at all. Basted is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you offer colour-matched sealant for buildings in Basted?
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.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
What do you need from us to quote?
Send photographs, drawings or a list of locations. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you work directly for building managers?
Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.

Site staff or a sealant specialist?
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Deal with small splits before they become leaks
- Make sure ventilation in wet areas is switched on and working
- Check sealant as part of routine building inspections
- Respect the cure time before reopening an area
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.
Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.
