About our commercial sealant contractors in Hersden
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and on a working site that usually surfaces as a leak, a stain or a complaint from occupiers. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in Hersden. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. The enquiries we see most involve smeared sealant across finishes from a rushed job and weathered facade sealant that no longer flexes, across floor and threshold joints, movement joints in walls and floors and washrooms and tea points. A specialist sealant contractor works differently from a general builder: on jobs in Hersden, preparation and product choice get the time they need.
Quotes for commercial sealant in Hersden can come from photos and a joint schedule, or from a walk-round, and the scope is set out in writing.
Places like Hersden tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. They’re not big jobs one by one, but their joints need the same preparation as anywhere.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Doing it in-house
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Shops, offices and hotels in and around Hersden
Hersden is in the South East, one of the UK’s drier regions. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Less than 3 miles from Hersden there are at least three named estates and business parks. Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it.
If you run a unit on an estate such as Canterbury Industrial Park, 0.6 miles east of Hersden, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. Sites a few miles apart, such as Canterbury Industrial Park and Chislet Business Park, can share one programme and one point of contact.

From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes a few hours to several days on most single sites, depending on joint lengths and access. Several jobs near Hersden can be grouped on one trip. Tell us your site hours and we will plan around them.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.

Common questions from Hersden clients
Is Hersden off your patch?
Not at all. Hersden 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.
Can the sealant on our Hersden premises match the finishes?
Yes, we can normally get close to most finishes from the product’s colour range. Send colour references or photographs and we will confirm what’s available for the product.
Does commercial sealant work come with a guarantee?
Our workmanship on each job is backed by a 12-month guarantee. We’re fully insured for public liability as well.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
When to call us in Hersden
If only one face has lost its grip, that’s an adhesion failure. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.
Look out for the following:
- Untidy joints in a reception, shop floor or lobby
- Sanitary sealant that has gone black and patchy
- Window and door perimeter joints that have cracked open
- Greasy, split joints in a kitchen or tea point
Offices and shops close to stations such as Sturry station, 1.9 miles south-west of Hersden, tend to be busy all day, so sealant work is planned around opening hours.

What we can’t put right
Before quoting, we check that sealant is the right answer. It won’t put right:
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Broken glass or blown double-glazed units
- Leaks from pipework, wastes or valves (that’s plumbing)
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Surfaces we seal
- Movement joints in walls and floors
- External facade joints
- Window and door perimeters
- Washrooms and tea points
- Kitchen worktops and splashbacks
- Floor and threshold joints

Why deal with it now?
A cheaper quote sometimes means the old bead stays in. Sealing over looks tidy at handover, then lifts once the joint starts moving. Our prices always include removal of the failed bead and full joint preparation, which is where the lasting value is. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
