Mastic sealing for commercial buildings in Watermill
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. Most enquiries involve mastic failing across several blocks on an estate and failed external movement joints, across balcony and threshold joints, communal entrances and stairwells and shopfronts below residential blocks. Searching for sealant specialists in Watermill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In and around smaller places like Watermill, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Log resealing dates block by block
- Start inspections with the most exposed faces
- Reduce knocks to communal area joints
- Plan resealing building by building rather than complaint by complaint
Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.
Why it’s worth doing now in Watermill
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. Resealing the perimeters is often the simpler fix when the frames themselves are sound. For buildings around smaller places like Watermill, 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.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Watermill can form part of a wider programme.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
When something else is needed
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Frames that are rotten, warped or broken
- Broken glass or failed sealed units
- Masonry that has broken away beside the joint
Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Mastic sealing around Watermill: how the place shapes the job
Watermill is within about 3 miles of the coast. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. Watermill sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.
Buildings close to stations like Crowhurst station, 1.9 miles north-east of Watermill, are often flats over shops, with frame mastic to keep sound. Site managers at schools like Bexhill High Academy can fit frame mastic into the summer works. If you own or manage units on a site such as Bexhill Enterprise Park, 1.5 miles south-east of Watermill, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Our process
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. Jobs in and around smaller places like Watermill are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Each building is checked on completion and the work carries our 12-month guarantee.
Before we start on site
