Work for main contractors and building owners
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in East Malling can sit alongside others in a wider programme.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
How we handle mastic sealing in East Malling
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. We work on shopfronts below residential blocks, communal kitchens and washrooms and communal entrances and stairwells, and what we are called in for most is damaged joints in communal entrances and corridors and a mix of products and colours from past repairs. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in East Malling, that means joint design, primers and backing rod as standard.
Converted and older buildings in and around East Malling often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

From enquiry to sign-off
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. What matters most for a job in East Malling is a clear list of what needs doing, so send photographs of each area. You’ll then get a fixed price for the work.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready

Questions we are asked in East Malling
Will you work in a care home in East Malling without moving residents out?
Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.
Can you quote for a block close to East Malling station?
Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you cover East Malling?
Yes. Sites across East Malling are covered, with one number for every area we cover.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Backing rod, priming and other preparation
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- Access details, including height
- Asbestos survey details if the building is older
- Clear photographs of the problem areas
- The type of building and who uses it
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to ring 01277 525 020 or use the quote form.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Share the asbestos register when you send details
- Ask residents or tenants to report leaks and draughts early
- Track which buildings were done and when
- Include mastic in your cyclical inspections
Keep records of when each building was resealed. 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. Once that happens, repairs come before resealing.
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
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 where general trades tend to cut corners.
Planned mastic for East Malling portfolios
There are two care or nursing homes within about 2 miles of East Malling. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings. East Malling is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
