Frontages, fit-outs and joints in Northfleet Green
Northfleet Green has at least three named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it. Northfleet Green has several hotels close by, all within 2 miles. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, and the work can be phased so the rest of the hotel keeps trading.
For tenants and agents on sites such as Imperial Business Park, which lies north-east of Northfleet Green, office fit-outs, reception joints and window perimeters are the usual sealant work. Occupiers with premises at both Imperial Business Park and Imperial Retail Park could have the sealant at each handled under one quote. Offices and shops close to stations such as Ebbsfleet International station, 2 miles north of Northfleet Green, tend to be busy all day, so sealant work is planned around opening hours.

Sealant applicators in Northfleet Green
Most of the buildings we seal stay open while we’re there. Work is scheduled around the site hours and access windows you give us; phasing keeps some washrooms, kitchens or entrances available while others are done. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. If you’re dealing with wall and floor joints that have lost their seal and shrunken sealant along kitchen worktops and splashbacks, we can help, on movement joints in walls and floors, floor and threshold joints and washrooms and tea points alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Northfleet Green, that means joint design, primers and backing rod as standard.
Occupied buildings in Northfleet Green need the work phased: we agree the order with you and hand back each area with its cure time.
Business units in the countryside around places like Northfleet 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, and a sealant colour that suits the building’s character is often part of the brief.
Work we carry out in Kent comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email the details over and we will come back to it.

Northfleet Green: questions and answers
Will our hotel in Northfleet Green need to close for the work?
Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.
Do you cover business parks and estates near Northfleet Green, such as Imperial Business Park?
Yes. Our area takes in Northfleet Green and its surroundings, with estates and business parks such as Imperial Business Park included. A few photos and the unit address let us price the work.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you work directly for building managers?
Yes. You can send details through our quote form.
How long does a job like this take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
When something else is needed
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Water from a services leak rather than a joint
- Roof leaks that only look like a joint problem
- Old mastic that tests positive for asbestos
If in doubt, call the office on 01277 525 020 or email us and we will say what we think.
Where we work in Northfleet Green
- Floor and threshold joints

Building owners, agents and FMs in Northfleet Green
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
How a job runs
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a few hours to several days on most single sites, depending on joint lengths and access. Rural sites near Northfleet Green may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We start with the evidence: photographs, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- Completed areas are signed off with you under our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Flag any permit to work we’ll need
- Share your working hours and any access restrictions

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
Advice
How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Which sealant the job calls for
- Whether the work must be split into stages
- Induction, permit and paperwork requirements
- The size and state of each joint
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- A wide shot and a close-up of the area
- The site address and postcode
- Any dates the work must fit around
- How the joints are reached, and at what height
Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, call the office on 01277 525 020 or use the quote form.
Should maintenance staff do it?
Paperwork matters too. 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.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Don’t let cleaning or traffic back on before the cure time is up
- Note dates and locations of sealant work for future planning
- Check joints after other trades have worked nearby
- On pre-2000 buildings, share the asbestos information before work starts
Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.
