Commercial mastic work in Hawthorn
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 looking after property in Hawthorn. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. If you have gaps behind commercial kitchen worktops and sinks and window and door perimeter joints that have cracked open, we can put it right, whatever the surface. For commercial sealant work in Hawthorn, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Occupied buildings in Hawthorn 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 Hawthorn are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.
A 12-month guarantee applies to all our work. If an installation problem shows up, ring 01277 525 020 or email us and we’ll arrange a return visit.

Our process
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Hawthorn are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- 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.
- We hand back each area with its cure time and our 12-month guarantee.
Before we start on site
- Flag any permit to work we will need
- Move anything stored against the joints
- Tell staff and tenants when we will be in

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Advice
General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Commercial clients in Hawthorn
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Note dates and locations of sealant work for future planning
- Check the asbestos register before anyone disturbs old sealant in an older building
- Make sure ventilation in wet areas is switched on and working
- Ask cleaners to use a soft cloth and mild cleaner on sealant
We stand behind the workmanship with a 12-month guarantee. File the handover note with the building records.
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. At that point it’s a repair job rather than a reseal.

Hawthorn: questions and answers
Is a smaller place like Hawthorn outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Our building in Hawthorn is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can one contractor look after sealant on all our buildings?
Yes, within the areas we cover: South East England, Greater London and Scotland. One contact and one process for every building makes a portfolio easier to manage.
Is failed sealant stripped out, or sealed over?
Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away, so it isn’t something we do.
How is commercial sealant work priced?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.
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 anything suspect is left until it has been tested.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Misted, cracked or failed glazing units (a glazier’s job)
- Walls or slabs moving more than any sealant can take
- Old mastic that tests positive for asbestos
Not sure which it is? You can call 01277 525 020 or send details through our quote form and we’ll tell you honestly.
What we seal
- Movement joints in walls and floors

What Hawthorn’s businesses ask us to seal
Hawthorn sits close to the coast, within about 2 miles. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. A matched colour is only half the brief on an exposed frontage. Two care or nursing homes sit less than 2 miles from Hawthorn. Care homes need tidy, cleanable joints in kitchens, corridors and communal rooms.
Occupiers with premises at both Eddington Business Park and Chislet Business Park could have the sealant at each handled under one quote. Offices at parks like Eddington Business Park (2.2 miles west of Hawthorn) have receptions, kitchens and glazed partitions where a tidy joint matters. Shops and cafés around stations like Herne Bay station (2.4 miles west of Hawthorn) trade from early, so work is timed around them.
Hawthorn is about 2 miles east of Herne Bay, in Kent. We send applicators to Hawthorn for sealant joints, handled exactly as we handle every other area. Hawthorn is one of 931 places we cover in Kent. Our London page has more on work in that area (56 miles or so).
Commercial sites across CT6 and CT3 are covered. We cover commercial and managed buildings on Campion Avenue, Sweechbridge Road and Heart in Hand Road. Main routes into Hawthorn include the A299, which helps when planning parking and deliveries for the job. We also cover Hillborough (1 mile north-west), Highstead (1 mile south), Bishopstone (1 mile north), Broomfield (1 mile west) and Beltinge (1 mile north-west) for sealant joints. Further afield, our area takes in Canterbury (7 miles south-west), Margate (9 miles east), Ramsgate (10 miles east), Broadstairs (11 miles east), Whitstable (6 miles west) and Deal (14 miles south-east).
Landmarks near Hawthorn
We work on buildings around The Huntsman And Horn Public House and Bishopstone Cliffs, among other places. The nearest railway station is Herne Bay station, about 2.4 miles west. Nearby you’ll also find Whitstable and Tankerton Hospital (5.4 miles west). For a walk, there’s West Blean and Thornden Woods.
Leave it or put it right?
It can be tempting to hold sealant work back until the next refurbishment. That’s reasonable for internal joints that are just tired-looking, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. For buildings around smaller places like Hawthorn, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.
